Abstract
Description
上下方向に風向を制御する上下風向板を備えた空気調和機に関する。 The present invention relates to an air conditioner including an up / down wind direction plate that controls the wind direction in the up / down direction.
壁掛型の空気調和機は、天井付近に設置され、空調空気の上下方向の吹出方向を調整する風向調整板（上下風向板）を備える。上下風向板を連続的にスイングさせて空調空気の吹出方向を上下方向に連続的に変更したり、上下風向板を略水平方向に向けて室内空間の温度分布を均一にしたりするなど、上下風向板により室内の気流分布を調整する。 The wall-mounted air conditioner is provided near the ceiling and includes a wind direction adjusting plate (up and down wind direction plate) that adjusts the vertical blowing direction of the conditioned air. Up and down wind direction, such as continuously swinging the up and down air direction plate to change the blowing direction of the conditioned air continuously in the up and down direction, or making the up and down wind direction plate in a substantially horizontal direction to make the temperature distribution in the indoor space uniform The airflow distribution in the room is adjusted by the board.
冷房運転時に上下風向板が略水平方向に固定されると、天井付近から水平に吹き出された空調空気は、部屋の空間の下側略半分の生活空間（天井高さ２.７ｍ、身長１.７ｍの場合床から約６３％の高さまでの空間）には直接的には届かず、壁などにぶつかる。その後、壁などにぶつかった空調空気は、風速が落ち、密度の高さにより下方向へ移動して、生活空間に届く。ユーザは、空調空気の温度により涼しさを感じることができるが、風速の落ちた空調空気からは気流による涼しさを得られない。これは、以下の式で説明することができる。
Ｑ＝α（ＴＳ−ＴＡ） …（式１）
Ｑ＝放熱量［Ｗ／ｍ2］
α＝対流熱伝達率［Ｗ／ｍ2℃］
ＴＳ＝皮膚温［℃］
ＴＡ＝空気温度［℃］
If the up-and-down wind direction plate is fixed in the horizontal direction during cooling operation, the conditioned air blown horizontally from the vicinity of the ceiling is approximately half the living space below the room space (ceiling height 2.7m, height 1. In the case of 7m, the space from the floor to a height of about 63% does not reach directly, but hits a wall. After that, the air-conditioned air that hits the walls, etc., decreases in wind speed, moves downward due to its high density, and reaches the living space. The user can feel coolness by the temperature of the conditioned air, but cannot obtain the coolness of the airflow from the conditioned air whose wind speed has dropped. This can be explained by the following equation.
Q = α (TS−TA) (Formula 1)
Q = heat dissipation [W / m 2 ]
α = Convective heat transfer coefficient [W / m 2 ° C]
TS = skin temperature [° C]
TA = air temperature [° C]
ただし、人体からの放熱の経路は対流、放射、蒸発、伝導の４種類あり、（式１）はこの４種類の中の対流のみについての放熱量を示している。本来は、
Ｑ総合＝Ｑ対流＋Ｑ放射＋Ｑ蒸発＋Ｑ伝導 …（式２）
であり、Ｑ総合が大きいほど涼しさを感じられる。ここでは簡単のため特別に記載しない限り対流による放熱量であるＱ対流をＱと記載する。
However, there are four types of heat dissipation paths from the human body: convection, radiation, evaporation, and conduction. (Equation 1) indicates the heat dissipation amount for only the convection among these four types. initially,
Q total = Q convection + Q radiation + Q evaporation + Q conduction (Formula 2)
And the bigger the Q synthesis, the cooler you feel. For simplicity, Q convection, which is the amount of heat released by convection, is described as Q unless otherwise specified.
放熱量Ｑが大きいほどより大きな涼しさを感じられる。（式１）における空調空気による涼しさは、空気温度ＴＡが小さくなることにより、（ＴＳ−ＴＡ）が大きくなり、放熱量Ｑが大きくなることによる。（式１）における気流による涼しさは、対流熱伝達率αにより表される。気流速度が大きいほど対流熱伝達率αは大きくなる。その結果放熱量Ｑも大きくなり、より涼しさを感じることができる。 The greater the heat dissipation amount Q, the greater the coolness. The coolness of the conditioned air in (Expression 1) is due to the fact that (TS-TA) increases and the heat dissipation amount Q increases as the air temperature TA decreases. The coolness due to the airflow in (Expression 1) is represented by the convective heat transfer coefficient α. The larger the air velocity, the greater the convective heat transfer coefficient α. As a result, the heat dissipation amount Q is also increased, and a cooler feeling can be felt.
しかしながら、従来の空気調和機では、気流速度が大きくなり、その結果、放熱量Ｑが大きくなり過ぎることによる寒さからの不快感を避けるため、冷房時には空調空気を水平方向に吹き出すように制御する。しかしながら、気流速度が小さいことによる放熱量の少なさにより、在室者が暑く不快に感じる場合がある。一方、従来の空気調和機では、上下風向板を上下方向にスイングさせて連続的に気流速度の大きな空調空気を生活空間に送風することで、気流による涼しさを提供する。しかしながら、連続的に放熱量が多いため、在室者が寒く不快に感じる場合がある。 However, in the conventional air conditioner, the air flow speed is increased, and as a result, in order to avoid the discomfort from the cold caused by the excessive heat dissipation amount Q, control is performed so that the conditioned air is blown out horizontally during cooling. However, the occupants may feel hot and uncomfortable due to the small amount of heat release due to the low air velocity. On the other hand, in the conventional air conditioner, the cooling by airflow is provided by swinging the vertical airflow direction plate in the vertical direction and continuously blowing conditioned air having a large airflow velocity into the living space. However, since the heat radiation amount is continuously large, the occupant may feel cold and uncomfortable.
これに対して、特許文献１は、室内の空気に対して空気調和処理を行う空気調和機構と、空気調和された空気の吹出方向を調整する風向調整板と、空気調和機構の処理能力を一時的に上昇させるパワフル運転を行うことが可能である制御部と、人が居る方向に空気が吹き出すように決定されている風向調整板の向きの設定値を記憶する記憶部と、を備え、制御部は、パワフル運転の指示入力がなされると、設定値に従って風向調整板の向きを制御する第１制御に切り替える空気調和機を開示する。室内のユーザに向けて空調空気を吹き出すことにより、放熱量を増大させ涼しさを感じられる空調状態とする。 On the other hand, Patent Document 1 temporarily describes an air conditioning mechanism that performs an air conditioning process on indoor air, a wind direction adjusting plate that adjusts a blowing direction of the air that has been conditioned, and a processing capacity of the air conditioning mechanism. And a control unit capable of performing powerful driving to raise automatically and a storage unit for storing a setting value of the direction of the wind direction adjusting plate determined so that air blows in the direction in which the person is present The section discloses an air conditioner that switches to a first control that controls the direction of the wind direction adjusting plate according to a set value when an instruction input for a powerful operation is made. By blowing air-conditioned air toward the user in the room, the heat radiation amount is increased and the air-conditioning state can be felt cool.
特許文献２は、室内の空気に対して空気調和処理を行う空気調和機構と、空気調和された空気の吹出方向を調整する風向調整板と、空気調和機構の処理能力を一時的に上昇させるパワフル運転を行うことが可能である制御部と、人感知センサとを備え、制御部は、冷房運転時において、通常運転時には風向調整板を略水平方向付近でスイングさせ、パワフル運転の指示入力がなされると、人感知センサからの情報に基づいて人が居る方向を含むように風向調整板のスイング範囲を変更する空気調和機を開示する。ユーザに向けて空調空気を吹き出すことにより、放熱量を増大させ涼しさを感じられる空調状態とする。 Patent Document 2 discloses an air conditioning mechanism that performs an air conditioning process on indoor air, a wind direction adjusting plate that adjusts the blowing direction of the air that has been conditioned, and a powerful system that temporarily increases the processing capacity of the air conditioning mechanism. A control unit capable of operation and a human sensor are provided, and during the cooling operation, the control unit swings the wind direction adjusting plate in the vicinity of the substantially horizontal direction during normal operation, and an instruction for powerful operation is input. Then, the air conditioner which changes the swing range of a wind direction adjustment board so that the direction where a person exists based on the information from a person detection sensor is included is disclosed. By blowing the conditioned air toward the user, the heat radiation amount is increased, and the air-conditioning state in which coolness can be felt is obtained.
しかしながら、スイング運転であっても、それが連続することで、連続的に放熱量Ｑが増大する。放熱量Ｑの連続的な増大は、寒さによる不快感となる。特許文献１，２では、空調空気の吹出方向にユーザを含むようにスイングの方向を調整するが、ユーザは連続して空調空気に曝されるため、Ｑの増大により寒さによる不快を感じる可能性がある。 However, even in the swing operation, the heat dissipation amount Q continuously increases due to the continuous operation. The continuous increase in the heat dissipation amount Q causes discomfort due to cold. In Patent Documents 1 and 2, the swing direction is adjusted so as to include the user in the conditioned air blowing direction. However, since the user is continuously exposed to the conditioned air, there is a possibility that the increase in Q may cause discomfort due to cold. There is.

以下、本発明を実施するための形態について、図面を用い説明する。まず、空気調和機の全体構成について図１を用いて説明する。図１は空気調和機の外観構成図である。 Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. First, the whole structure of an air conditioner is demonstrated using FIG. FIG. 1 is an external configuration diagram of an air conditioner.
室内を空気調和する空気調和機は、室内に設置される室内機と、室外に設置される室外機と、空気調和機の運転様態を設定する空調設定装置（リモコン）と、室内機と室外機とを繋ぐ接続配管とを備える。 An air conditioner that harmonizes the air in the room includes an indoor unit installed indoors, an outdoor unit installed outdoors, an air conditioning setting device (remote control) that sets the operation mode of the air conditioner, an indoor unit, and an outdoor unit. And a connecting pipe that connects the two.
室外機は、圧縮機、室外送風機、室外熱交換器等を備える。室外機の圧縮機と室外熱交換器は、接続配管の２本の冷媒配管により、後述する室内機の熱交換器（図２参照）と接続され、冷媒を循環させることにより冷凍サイクルを構成する。 The outdoor unit includes a compressor, an outdoor blower, an outdoor heat exchanger, and the like. The compressor of the outdoor unit and the outdoor heat exchanger are connected to a heat exchanger (see FIG. 2) of the indoor unit, which will be described later, by two refrigerant pipes of the connection pipe, and constitute a refrigeration cycle by circulating the refrigerant. .
次に、空気調和機を構成する室内機について図２を用いて説明する。図２は室内機の側断面図である。室内機は、筐体ベースの中央部に室内熱交換器と、室内熱交換器の下流側に室内熱交換器の幅と略等しい長さの横流ファン方式の送風ファンと、室内熱交換器で結露した凝縮水を受ける露受皿とを備える。 Next, the indoor unit which comprises an air conditioner is demonstrated using FIG. FIG. 2 is a side sectional view of the indoor unit. The indoor unit is composed of an indoor heat exchanger at the center of the casing base, a cross-flow fan blower fan having a length substantially equal to the width of the indoor heat exchanger downstream of the indoor heat exchanger, and an indoor heat exchanger. A dew receiving tray for receiving condensed condensed water.
また、室内機の筐体ベースには、フィルタ、上下風向板、左右風向板等の基本的な内部構造体が取り付けられる。これらを化粧枠で覆い、化粧枠の前面に前面パネルを取り付けることにより、筐体ベース、化粧枠、前面パネルからなる筐体に内包され室内機を構成する。 In addition, basic internal structures such as a filter, an up / down wind direction plate, and a left / right wind direction plate are attached to the housing base of the indoor unit. These are covered with a decorative frame, and a front panel is attached to the front surface of the decorative frame, so that the indoor unit is included in a casing composed of a casing base, a decorative frame, and a front panel.
空気吸込口は、室内機の上部に設けられた上側空気吸込部と、室内機の前面に設けられた前側空気吸込部とで構成される。ここで、前面パネルは、下端部に設けた回動軸を支点として駆動モータにより回動され、空気調和機の運転時に前側空気吸込部を開くように構成される。これにより、室内空気は、空気調和機の運転時に前側空気吸込部からも室内機内に吸引される。なお、空気調和機の運転停止時には、前面パネルを回動し、前側空気吸込部を閉じるように制御される。化粧枠の下面に形成される空気吹出口は、前面パネルと化粧枠との分割部に隣接して配置され、室内機の内部の吹出風路に連通する。 The air suction port is composed of an upper air suction part provided at the upper part of the indoor unit and a front air suction part provided at the front surface of the indoor unit. Here, the front panel is rotated by a drive motor with a rotation shaft provided at the lower end as a fulcrum, and is configured to open the front air suction portion when the air conditioner is in operation. Thereby, indoor air is also attracted | sucked in an indoor unit also from the front side air suction part at the time of driving | running of an air conditioner. When the operation of the air conditioner is stopped, the front panel is rotated so that the front air suction part is closed. The air blower outlet formed in the lower surface of the decorative frame is disposed adjacent to the divided portion of the front panel and the decorative frame, and communicates with the blowout air path inside the indoor unit.
フィルタは室内熱交換器の吸込側を覆うように配置される。フィルタにより、空気吸込口（上側空気吸込部、前側空気吸込部）から吸い込まれた室内空気中に含まれる塵埃が取り除かれる。また、露受皿は室内熱交換器の前後両側の下端部下方に配置され、冷房運転時や除湿運転時に室内熱交換器に発生する凝縮水を受ける。露受皿にて集められた凝縮水は、接続配管の内部に設けられたドレン配管を通して室外に排出される。 The filter is disposed so as to cover the suction side of the indoor heat exchanger. The filter removes dust contained in the indoor air sucked from the air suction port (upper air suction part, front air suction part). The dew tray is disposed below the lower ends of the front and rear sides of the indoor heat exchanger and receives condensed water generated in the indoor heat exchanger during cooling operation and dehumidifying operation. The condensed water collected in the dew tray is discharged out of the room through a drain pipe provided inside the connection pipe.
送風ファンが回転すると、室内空気が空気吸込口から室内熱交換器へ流れる。そして、室内熱交換器にて温度調整、湿度調整された空調空気は、送風ファンを通って送風ファンの長さに略等しい幅の吹出風路に流れる。その後、空調空気は、吹出風路に位置する左右風向板で左右方向を偏向されるとともに、空気吹出口に位置する上下風向板で上下方向を偏向されて、室内に吹き出す。 When the blower fan rotates, room air flows from the air inlet to the indoor heat exchanger. Then, the conditioned air whose temperature is adjusted and humidity-adjusted by the indoor heat exchanger flows through the blower fan to the blowout air passage having a width substantially equal to the length of the blower fan. Thereafter, the conditioned air is deflected in the left-right direction by the left and right wind direction plates located in the blow-out air passage, and is deflected in the up-down direction by the up-and-down air direction plate located in the air outlet, and blows out into the room.
２枚の上下風向板は、両端部に設けた回動軸を支点にして、リモコンの指示等に応じて、駆動モータにより空気調和機の運転時に所要の角度まで回動されて空気吹出口を開き、その状態に保持される。空気調和機の運転停止時には、上下風向板を回動し、空気吹出口を閉じるように制御される。上下風向板は、閉鎖状態で、吹出風路をほぼ隠蔽して室内機の底面に連続するように構成されている。 The two up and down wind direction plates are pivoted to the required angle when the air conditioner is operated by the drive motor according to instructions from the remote controller, etc., with the pivot shafts provided at both ends as fulcrums. Open and hold in that state. When the operation of the air conditioner is stopped, control is performed so that the vertical air direction plate is rotated and the air outlet is closed. The up-and-down wind direction plate is configured to be confined to the bottom surface of the indoor unit in a closed state, substantially concealing the blowing air path.
左右風向板は、下端部に設けた回動軸を支点にして、リモコンからの指示等に応じて、駆動モータにより所要の角度まで回動され、その状態に保持される。 The left and right wind direction plates are rotated to a required angle by a drive motor in response to an instruction from a remote controller or the like with a rotation shaft provided at the lower end as a fulcrum, and are held in that state.
このように、空気調和機の室内機は、リモコンからの指示に応じて、上下風向板、左右風向板を所要の角度まで回動して、空調空気を空気吹出口から上下左右に偏向し所望の方向に吹き出す。 As described above, the indoor unit of the air conditioner rotates the vertical wind direction plate and the left and right wind direction plates to a required angle in accordance with an instruction from the remote controller, and deflects the conditioned air from the air outlet to the desired direction. Blow out in the direction of
なお、リモコンからの指示等により、空気調和機の運転中に上下風向板、左右風向板を周期的に揺動させ、室内の広範囲に周期的に空調空気を吹き出すこともできる。 In addition, according to an instruction from a remote controller or the like, it is possible to periodically oscillate the conditioned air over a wide range in the room by periodically swinging the vertical and horizontal wind direction plates during operation of the air conditioner.
室内機は、前側空気吸込部の近くに、室内機へ吸い込まれる室内空気の温度（以下「吸込み空気温度」という。）を検出する室内機サーミスタを備える。また、室内機は、室内機へ吸い込まれる室内空気の湿度を検出する室内湿度センサを備える。 The indoor unit includes an indoor unit thermistor that detects the temperature of indoor air sucked into the indoor unit (hereinafter referred to as “suction air temperature”) near the front air suction unit. The indoor unit includes an indoor humidity sensor that detects the humidity of the indoor air sucked into the indoor unit.
ここで、室内機送受光部の構成について説明する。室内機の化粧枠の下部には、室内機とリモコンとの間で赤外線信号を送受信するための室内機送受光部と、空気調和機の運転状況を表示する表示装置とが配置される。室内機送受光部は、リモコンからの赤外線信号を受信するＩＲレシーバと、室内機が設置された室内の中央に向けて赤外線信号を送信する中央送信素子と、室内機が設置された室内の左側に向けて赤外線信号を送信する左送信素子と、室内機が設置された室内の右側に向けて赤外線信号を送信する右送信素子とを備える。 Here, the configuration of the indoor unit transmission / reception unit will be described. Below the decorative frame of the indoor unit, an indoor unit transmission / reception unit for transmitting and receiving infrared signals between the indoor unit and the remote controller, and a display device for displaying the operating status of the air conditioner are arranged. The indoor unit transmission / reception unit includes an IR receiver that receives an infrared signal from a remote controller, a central transmission element that transmits an infrared signal toward the center of the room where the indoor unit is installed, and a left side of the room where the indoor unit is installed A left transmission element that transmits an infrared signal toward the right side, and a right transmission element that transmits an infrared signal toward the right side of the room in which the indoor unit is installed.
また、室内機は、内部の電装品ボックスに制御基板を備え、この制御基板にマイコンと記憶装置が設けられる。マイコンは、室内機サーミスタ、室内湿度センサ等の各種のセンサからの信号を受け取ると共に、室内機送受光部（ＩＲレシーバ）を介してリモコンからの赤外線信号を受け取る。マイコンは、これらの信号に基づいて、送風ファンの駆動モータ、前面パネルの駆動モータ、上下風向板の駆動モータ、左右風向板の駆動モータ等を制御すると共に、接続配管の電線を介して室外機（圧縮機、室外送風機等）との通信を司り、室内機および室外機を統括して制御する。また、マイコンは、室内機送受光部（中央送信素子、左送信素子、右送信素子）を介して、リモコンに赤外線信号を送信することができる。 The indoor unit includes a control board in an internal electrical component box, and a microcomputer and a storage device are provided on the control board. The microcomputer receives signals from various sensors such as an indoor unit thermistor and an indoor humidity sensor, and also receives an infrared signal from a remote controller via an indoor unit transmission / reception unit (IR receiver). Based on these signals, the microcomputer controls the drive motor for the blower fan, the drive motor for the front panel, the drive motor for the up / down air direction plate, the drive motor for the left / right air direction plate, and the outdoor unit via the wires of the connecting pipe. Controls communication with (compressor, outdoor blower, etc.) and controls the indoor unit and outdoor unit in an integrated manner. Further, the microcomputer can transmit an infrared signal to the remote controller via the indoor unit transmission / reception unit (center transmission element, left transmission element, right transmission element).
次に、本実施例の上下風向板の運転制御について図３から図６を用いて説明する。本実施例の空気調和機は、空気吸込口及び空気吹出口と、空気吸込口から室内空気を吸い込み、空気調和された室内空気を空気吹出口から吹き出す送風ファンと、空気調和された調和空気を上下方向に偏向する上下風向板と、上下風向板の上下方向位置を制御する制御装置と、を備え、上下風向板により在室者が位置しない方向に調和空気を向ける第１状態と、第１状態から上下風向板をスイングさせて在室者を含む方向に一時的に調和空気を向ける第２状態と、を繰り返すように、上下風向板を制御する。尚、図３に示すような上下風向板により在室者が位置しない方向に調和空気を向ける第１状態と、図４に示すような第１状態から上下風向板をスイングさせて在室者を含む方向に一時的に調和空気を向ける第２状態とを繰り返すことを、以下「断続スイング運転」という。尚、本実施例では、特に、冷房運転時の第１状態においては上下風向板を略水平方向の定位置に固定し、暖房運転時の第１状態においては上下風向板を在室者が存在する位置よりも手前下方の定位置に固定する。両状態を合わせて以下「定位置吹き出し」という。 Next, the operation control of the up-and-down wind direction plate of a present Example is demonstrated using FIGS. 3-6. The air conditioner of the present embodiment includes an air inlet and an air outlet, a blower fan that sucks room air from the air inlet and blows out air-conditioned room air from the air outlet, and air-conditioned air. A first state in which an up-and-down air direction plate that deflects in an up-and-down direction and a control device that controls a vertical position of the up-and-down air direction plate and directs conditioned air in a direction in which no occupant is located by the up-and-down air direction plate; The vertical wind direction plate is controlled to repeat the second state in which the vertical wind direction plate is swung from the state and the conditioned air is temporarily directed in the direction including the occupant. In addition, the up-and-down wind direction plate as shown in FIG. 3 causes the conditioned air to be directed in a direction where the resident person is not located, and the up-and-down wind direction plate is swung from the first state as shown in FIG. Repeating the second state in which the conditioned air is temporarily directed in the including direction is hereinafter referred to as “intermittent swing operation”. In this embodiment, in particular, in the first state during the cooling operation, the up-and-down air direction plate is fixed at a fixed position in a substantially horizontal direction, and in the first state during the heating operation, there are persons in the room. Fix it at a fixed position in front of you. Together, both states are referred to as “in-place balloons”.
断続スイング制御の指示入力を受けた場合、定位置吹き出し（図３）とスイング吹き出し（図４）とを交互に行う（図５、図６）。定位置吹き出しの状態では、例えば冷房運転では、略水平方向へ上下風向板を向け、空調空気を略水平方向に吹き出す。一方、暖房運転では、在室者が存在する位置よりも手前下方に上下風向板を向け、空調空気を空気調和機下方に吹き出す。 When an instruction input for intermittent swing control is received, a fixed position balloon (FIG. 3) and a swing balloon (FIG. 4) are alternately performed (FIGS. 5 and 6). In the state of blowing out at a fixed position, for example, in the cooling operation, the up / down air direction plates are directed in the substantially horizontal direction, and the conditioned air is blown out in the substantially horizontal direction. On the other hand, in the heating operation, the up-and-down wind direction plate is directed toward the front and lower than the position where the occupant is present, and the conditioned air is blown out below the air conditioner.
ここで、例えば冷房運転時に、断続スイング制御の指示入力を受けると、上下風向板を所定の回数スイングさせるスイング吹き出しと、上下風向板を略水平方向に位置させ所定時間吹き出す定位置吹き出しを繰り返す。具体的には、例えば、断続スイング制御の指示入力を受けると、上下風向板を１回スイングさせ、その５分間は水平方向へ上下風向板を向けて固定し定位置吹き出しを行う。さらに定位置吹き出しを５分間行った後には再び上下風向板を１回スイングさせる。 Here, for example, when an instruction input for intermittent swing control is received during the cooling operation, a swing balloon that swings the vertical wind direction plate a predetermined number of times and a fixed position balloon that positions the vertical wind direction plate in a substantially horizontal direction and blows out for a predetermined time are repeated. Specifically, for example, when an instruction input for intermittent swing control is received, the vertical wind direction plate is swung once, and the vertical wind direction plate is fixed in the horizontal direction for 5 minutes and then blown out at a fixed position. Further, after blowing out at a fixed position for 5 minutes, the up / down wind direction plate is swung once again.
これにより、連続して上下風向板をスイングさせる場合に生じる寒さによる不快感を防ぐことができるとともに、上下風向板を略水平方向に向け続けた場合に生じる気流の無い暑さによる不快感も防ぐことができる。従って、気流による涼しさを感じつつ寒さによる不快感を抑制した快適な温熱環境を提供することができる。 As a result, it is possible to prevent the discomfort due to the cold that occurs when the up-and-down wind direction plate is swung continuously, and also to prevent the discomfort due to the heat without airflow that occurs when the up-and-down wind direction plate is kept oriented substantially in the horizontal direction. be able to. Therefore, it is possible to provide a comfortable thermal environment in which the discomfort due to the cold is suppressed while feeling the coolness due to the airflow.
ここで、上下風向板のスイング回数を１回としたのは、複数回スイングすることにより、気流による放熱の増大で寒さを感じる危険性を考慮したからであり、室温が高い場合など放熱量を増大させたい場合には、複数回スイングすることにより、放熱量を増大させより涼しさを感じさせることができる。 Here, the reason why the number of swings of the up-and-down wind direction plate is set to one time is to consider the danger of feeling cold due to the increase in heat dissipation due to the airflow by swinging multiple times. When it is desired to increase, the amount of heat radiation can be increased and the cooler can be felt by swinging a plurality of times.
以上説明したように、本実施例においては、上下風向板により在室者が位置しない方向に調和空気を向ける第１状態（例えば、冷房時では略水平方向）と、第１状態から上下風向板をスイングさせて在室者を含む方向に一時的に調和空気を向ける第２状態と、を繰り返すように上下風向板を制御する。従来の空気調和機でも、上下風向板を一定位置で固定して吹き出す制御も、上下風向板をスイングさせる制御も行われていた。しかし、上下風向板を定位置で固定して吹き出す制御の場合には、上下風向板が略水平方向に向けられているため、生活空間には気流速度の低下した空調空気が生活空間の上部から沈んでくるのみで、速度の低下した空調空気から気流による体からの放熱量を増大させることはできず、気流による涼しさを感じることはできなかった。また上下風向板をスイングさせる制御の場合には、室内機から吹き出された気流速度の高い空調空気は数秒に一回生活空間に供給されるため、数秒に一回皮膚からの放熱量が増大することによる寒さを感じる危険性があった。そこで、本発明の空気調和機では、上下風向板により在室者が位置しない方向に調和空気を向ける第１状態（例えば、冷房時では略水平方向）と、第１状態から上下風向板をスイングさせて在室者を含む方向に一時的に調和空気を向ける第２状態と、を繰り返すように上下風向板を制御することで、気流による涼しさを感じつつ寒さによる不快感の無い快適な温熱環境を提供することを可能とした。 As described above, in the present embodiment, the first state (for example, the substantially horizontal direction during cooling) in which conditioned air is directed by the up-and-down air direction plate in the direction where the occupant is not located, and the up-and-down air direction plate from the first state. The vertical wind direction plate is controlled to repeat the second state in which the conditioned air is temporarily directed in the direction including the occupant by swinging the occupant. Even in a conventional air conditioner, control for blowing the vertical wind direction plate fixed at a fixed position and control for swinging the vertical wind direction plate have been performed. However, in the case of control in which the vertical wind direction plate is fixed and blown out at a fixed position, the vertical wind direction plate is directed in a substantially horizontal direction. The amount of heat released from the body due to the airflow could not be increased from the conditioned air whose speed decreased, and the coolness due to the airflow could not be felt. In the case of control for swinging the vertical wind direction plate, the conditioned air blown out from the indoor unit is supplied to the living space once every few seconds, so the amount of heat released from the skin increases once every few seconds. There was a danger of feeling the cold due to things. Therefore, in the air conditioner of the present invention, the upper and lower wind direction plates swing the conditioned air in a direction in which no occupants are located (for example, the substantially horizontal direction during cooling), and swing the upper and lower wind direction plates from the first state. By controlling the up-and-down wind direction plate to repeat the second state in which the conditioned air is temporarily directed in the direction including the occupants, comfortable heat without feeling of discomfort due to cold while feeling cool by the airflow It was possible to provide an environment.
尚、本実施例においては、冷房運転時を例にして説明したが、本発明の断続スイング制御は、暖房運転時にも適用することができる。 In the present embodiment, the cooling operation is described as an example, but the intermittent swing control of the present invention can be applied also during the heating operation.
また、本実施例では、冷房運転時又は暖房運転時に係らず、断続スイング制御を行うように指示入力された場合には、上下風向板をスイングさせるスイング吹き出しと、上下風向板を固定して吹き出す定位置吹き出しとを交互に行う例を説明した。しかしながら、冷房時に断続スイングの指示入力がある場合のみ、スイング吹き出しと定位置吹き出しとを交互に行うよう上下風向板の向きを制御してもよい。これにより、冷房運転時の気流による涼しさの向上と寒さによる不快感の回避とを実感させることができる。 Further, in this embodiment, when an instruction is input to perform intermittent swing control regardless of the cooling operation or the heating operation, the swing blowout for swinging the vertical wind direction plate and the vertical wind direction plate are fixed and blown out. An example of alternately performing fixed position balloons has been described. However, the direction of the up-and-down airflow direction plate may be controlled so that the swing blowout and the fixed-position blowout are alternately performed only when there is an intermittent swing instruction input during cooling. Thereby, the improvement of the coolness by the airflow at the time of air_conditionaing | cooling operation and the avoidance of the discomfort by cold can be actualized.
また、本実施例においては、在室者が位置しない方向に調和空気を向ける第１状態として、具体的には、例えば冷房運転時では、上下風向板を略水平方向に固定させる状態としたが、例えば暖房運転時では、在室者が存在する位置よりも手前下方に上下風向板を向け、空調空気を空気調和機下方に吹き出すようにする。これにより、在室者が位置しない方向に調和空気を向ける第１状態において、冷風又は温風を確実に在室者に向けないように制御することができる。 In the present embodiment, the first state in which the conditioned air is directed in the direction in which no occupant is located, specifically, for example, in the cooling operation, the vertical wind direction plate is fixed in a substantially horizontal direction. For example, at the time of heating operation, the up-and-down wind direction plate is directed toward the front and lower than the position where the occupant is present, and the conditioned air is blown out below the air conditioner. Thereby, in the 1st state which directs conditioned air in the direction where a occupant is not located, it can control so that cold air or warm air may not be directed to an occupant reliably.
また、本実施例においては、在室者が位置しない方向に調和空気を向ける第１状態として、具体的には、例えば冷房運転時では上下風向板を略水平方向に固定させる状態としたが、在室者が位置しない範囲で上下風向板をスイングさせるようにしてもよい。具体的には、冷房運転時であれば、水平方向周辺で上下風向板をスイングさせてもよいし、水平方向よりも上方の範囲内での上下風向板をスイングさせてもよい。このような運転により、在室者が位置しない方向に調和空気を向ける第１状態であっても、室内に気流の変化を生じさせ、室内の温度をより早く均一化することができる。 Further, in the present embodiment, as the first state in which the conditioned air is directed in the direction in which the occupant is not located, specifically, for example, in the cooling operation, the upper and lower wind direction plates are fixed in a substantially horizontal direction. You may make it swing an up-and-down wind direction board in the range in which a resident is not located. Specifically, during the cooling operation, the vertical wind direction plate may be swung around the horizontal direction, or the vertical wind direction plate in a range above the horizontal direction may be swung. By such an operation, even in the first state in which conditioned air is directed in a direction in which no occupants are located, a change in the airflow can be generated in the room, and the room temperature can be equalized more quickly.
また、本実施例においては、上下風向板をスイングさせて在室者を含む方向に一時的に調和空気を向けるようにしたが、この場合、人検知手段等により在室者の位置情報を入手している場合は、この在室者の位置情報等を利用して、在室者を含む方向に一時的に調和空気を向けることができる。一方、人検知手段等を備えずに在室者の位置情報を入手できない場合であっても、上下風向板が最大限可働する範囲で上下風向板をスイングさせることにより、冷風又は温風を在室者に向けて確実に送風させることができる。 Further, in this embodiment, the conditioned air is temporarily directed in the direction including the occupant by swinging the vertical wind direction plate. In this case, the position information of the occupant is obtained by the human detection means or the like. If it is, the conditioned air can be temporarily directed in the direction including the occupant using the position information of the occupant. On the other hand, even if the position information of the occupants cannot be obtained without providing human detection means etc., it is possible to cool or warm air by swinging the vertical wind direction plate within the range where the vertical wind direction plate can operate to the maximum extent. The air can be reliably blown toward the occupants.
次に、本発明の第２の実施例について図面を用いて説明する。本実施例においては、上下風向板により在室者が位置しない方向に調和空気を向ける第１状態の運転時間（ＴＴ）よりも、上下風向板をスイングさせて在室者を含む方向に一時的に調和空気を向ける第２状態の運転時間（ＴＳ）のほうが短くなるように上下風向板を制御する（図７）。つまり、ＴＳ＜ＴＴとなるようにそれぞれの運転時間を設定する。 Next, a second embodiment of the present invention will be described with reference to the drawings. In the present embodiment, the upper and lower wind direction plates are temporarily moved in the direction including the occupants by swinging the upper and lower wind direction plates than the operating time (TT) in the first state in which the conditioned air is directed in the direction in which the occupants are not located. The up-and-down wind direction plate is controlled so that the operation time (TS) in the second state in which the conditioned air is directed to becomes shorter (FIG. 7). That is, each operation time is set so that TS <TT.
これにより、スイング吹き出しにより空調空気を生活空間に供給することによる温度と気流による人体からの放熱量が増大（（式１）におけるＴＳの低下とαの増大によるＱの増大）する時間に対し、定位置吹き出しにより温度のみによる人体からの放熱量のみが増大する時間を長くすることで、例えば冷房運転時であれば寒さによる不快感をより確実に回避することができる。 As a result, the amount of heat released from the human body due to the temperature and airflow due to the supply of conditioned air to the living space by swing blowout increases (the decrease in TS in (Equation 1) and the increase in Q due to the increase in α), By lengthening the time during which only the amount of heat released from the human body due to temperature alone is increased by blowing out at a fixed position, for example, during cooling operation, discomfort due to cold can be avoided more reliably.
具体的には、例えば、一回スイングする時間がおよそ１０秒である場合に、スイング吹き出しの時間をスイング１回分の１０秒とする。また定位置吹き出しの時間を、人が温熱的な快適さに慣れるまでの時間である５分とする。この場合、スイング吹き出しの時間は定位置吹き出しの時間より短く、スイング吹き出しによる気流の増大に伴う放熱量の増加で寒さによる不快を感じる前にスイング吹き出しから定位置吹き出しに切り替えることができ、寒さによる不快を感じることを抑制することができる。また、定位置吹き出しにより低下した気流速度により放熱量が低下したことによる暑さによる不快を感じる前に、スイング吹き出しに切り替えることで、暑さによる不快を感じることを抑制することができる。尚、定位置吹き出しの時間を５分間として例えたのは、人は快適と感じるような空間に入ってからおよそ５分間でその快適さに慣れるため、スイングによる放熱量の増大で快適さを感じてからおよそ５分後にスイングすることで、快適さに慣れたころに再び快適さを提供することができるためである。 Specifically, for example, when the time for one swing is approximately 10 seconds, the swing balloon time is set to 10 seconds for one swing. In addition, the time for blowing out the fixed position is set to 5 minutes, which is the time until the person gets used to the thermal comfort. In this case, the swing balloon time is shorter than the fixed position balloon time, and the swing balloon can be switched to the fixed position balloon before feeling uncomfortable due to the cold due to the increase in the heat radiation accompanying the increase in the air flow due to the swing balloon. Feeling uncomfortable can be suppressed. Moreover, it is possible to suppress the discomfort due to the heat by switching to the swing air balloon before the discomfort due to the heat due to the decrease in the heat radiation amount due to the airflow velocity decreased due to the in-situ air balloon. In addition, the time for blowing out at a fixed position was set as 5 minutes because people get used to the comfort in about 5 minutes after entering a space where they feel comfortable. This is because, by swinging about 5 minutes later, comfort can be provided again when the user gets used to comfort.
（式１）の通り、対流による放熱量は、人体周囲の空気温度と対流熱伝達率に大きく依存する。また、対流熱伝達率は、気流速度に大きく依存する。すなわち、冷房や暖房による空調空気が人体周囲に供給されることにより、人体からの放熱量は、冷房時には急増し、暖房時には急減する。人体からの放熱量が急増または急減する頻度、すなわち断続スイングの頻度は１分から１０分に１回の連続した１スイングから５スイングであると、例えば冷房時には積極的な快適性を得やすい。より好ましくは、５分に１回の１スイング程度であると、より大きな積極的な快適性を得やすく、また気流が度々体に当たることによる喧騒さも感じにくい。 As shown in (Formula 1), the amount of heat released by convection greatly depends on the air temperature around the human body and the convective heat transfer coefficient. Moreover, the convective heat transfer coefficient greatly depends on the airflow velocity. That is, by supplying air-conditioned air by cooling or heating around the human body, the amount of heat released from the human body increases rapidly during cooling and decreases rapidly during heating. When the amount of heat released from the human body suddenly increases or decreases, that is, the frequency of the intermittent swing is from 1 to 5 consecutive swings every 1 to 10 minutes, it is easy to obtain positive comfort during cooling, for example. More preferably, if it is about one swing per 5 minutes, it is easy to obtain greater positive comfort, and it is difficult to feel the noise caused by airflow hitting the body frequently.
本発明の第３の実施例について図面を用いて説明する。本実施例は、在室者からの放熱量が大きいほど在室者からの放熱量が小さくなるように（在室者からの放熱量が小さいほど在室者からの放熱量が大きくなるように）、上下風向板により在室者が位置しない方向に調和空気を向ける第１状態の運転時間に対する上下風向板をスイングさせて在室者を含む方向に一時的に調和空気を向ける第２状態の運転時間を制御する。 A third embodiment of the present invention will be described with reference to the drawings. In this embodiment, the greater the amount of heat radiated from the occupant, the smaller the amount of heat radiated from the occupant (the smaller the amount of heat radiated from the occupant, the greater the amount of heat radiated from the occupant. ), The conditioned air is directed in the direction in which the occupant is not located by the up-and-down wind direction plate, and the conditioned air is temporarily directed in the direction including the occupant by swinging the up-and-down wind direction plate with respect to the operation time in the first state. Control the running time.
具体的には、在室者からの放熱量が大きいほど、在室者からの放熱量が小さくなるように、上下風向板により在室者が位置しない方向に調和空気を向ける第１状態の運転時間に対する上下風向板をスイングさせて在室者を含む方向に一時的に調和空気を向ける第２状態の運転時間を制御する。 Specifically, the operation in the first state in which conditioned air is directed in a direction in which the occupant is not located by the vertical wind direction plate so that the radiant heat from the occupant becomes smaller as the radiant amount from the occupant increases. The operation time in the second state in which the conditioned air is temporarily directed in the direction including the occupants by swinging the vertical wind direction plate with respect to time is controlled.
この場合、設定室温と室温との差が大きいほどスイング吹き出し（第２状態）の時間を長くすることができる（図８）。例えば、設定室温が２７度で室温が２９度の場合ではスイング吹き出しの時間を短くし（例えばスイング１回分の１０秒）、設定室温が２７度で室温が３５度の場合ではスイング吹き出しの時間を長くする（例えばスイング３回分の３０秒）ことで、ユーザが求めている放熱量（（式１）におけるＱ）に対し、生活空間の温度と設定室温との差が小さく放熱量が大きい（ＴＳの低さによるＱの増大）場合には気流による放熱量の増大を減らし（αを小さくしてＱの増大を低くする）、生活空間の温度と設定室温との差が大きく放熱量が小さい（ＴＳの高さによるＱの低減）場合には気流による放熱量を増やす。これにより、室温と設定室温との差が小さい場合には気流による放熱量の増大による寒さの不快感を避けることができ、また室温と設定室温との差が大きい場合には気流による放熱量の増大で涼しさを得ることができる。 In this case, the longer the difference between the set room temperature and the room temperature, the longer the swing balloon (second state) time can be (FIG. 8). For example, when the set room temperature is 27 degrees and the room temperature is 29 degrees, the swing balloon time is shortened (for example, 10 seconds for one swing), and when the set room temperature is 27 degrees and the room temperature is 35 degrees, the swing balloon time is decreased. By increasing the length (for example, 30 seconds for three swings), the difference between the temperature of the living space and the set room temperature is small with respect to the amount of heat released by the user (Q in (Expression 1)) (TS is large) In the case of Q increase due to low air flow), the increase in heat release due to airflow is reduced (α is reduced to reduce the increase in Q), and the difference between the living space temperature and the set room temperature is large and the heat release is small ( In the case of reduction of Q due to the height of TS), the heat radiation amount due to the airflow is increased. As a result, when the difference between the room temperature and the set room temperature is small, the discomfort of the cold caused by the increase in the heat dissipation due to the airflow can be avoided, and when the difference between the room temperature and the set room temperature is large, the heat dissipation due to the airflow can be avoided. Increased coolness can be obtained.
一方、設定室温と室温との差が大きいほど定位置吹き出し（第１状態）の時間を短くすることができる（図９）。例えば設定室温が２７度で室温が２９度の場合では定位置吹き出し時間を長くし（例えば人が快適さに慣れる時間の２倍の１０分）、設定室温が２７度で室温が３５度の場合では定位置吹き出し時間を短くする（例えば人が快適さに慣れる時間の５分）ことで、ユーザが求めている放熱量（（式１）におけるＱ）に対し、生活空間の温度と設定室温との差が小さく放熱量が大きい（ＴＳの低さによるＱの増大）場合には気流による放熱量の増大を減らし（αを小さくしてＱの増大を低くする）、生活空間の温度と設定室温との差が大きく放熱量が小さい（ＴＳの高さによるＱの低減）場合には気流による放熱量の増大を増やす。これにより、室温と設定室温との差が小さい場合には気流による放熱量の増大による寒さの不快感を避けることができ、また室温と設定室温との差が大きい場合には気流による放熱量の増大で涼しさを得ることができる。 On the other hand, as the difference between the set room temperature and the room temperature is larger, the time required for blowing out the fixed position (first state) can be shortened (FIG. 9). For example, when the set room temperature is 27 ° C and the room temperature is 29 ° C, the fixed position blowing time is lengthened (for example, 10 minutes which is twice as long as the time when a person gets used to comfort), and the set room temperature is 27 ° C and the room temperature is 35 ° C. Then, by shortening the home position blowing time (for example, 5 minutes of time when a person gets used to comfort), the temperature of the living space and the set room temperature with respect to the amount of heat released by the user (Q in (Equation 1)) If the difference between the two is small and the heat dissipation is large (Q increases due to the low TS), the increase in the heat dissipation due to the airflow is reduced (α is decreased by decreasing α), the living space temperature and the set room temperature Is large and the amount of heat released is small (reduction of Q due to the height of TS), the increase in the amount of heat released by the airflow is increased. As a result, when the difference between the room temperature and the set room temperature is small, the discomfort of the cold caused by the increase in the heat dissipation due to the airflow can be avoided, and when the difference between the room temperature and the set room temperature is large, the heat dissipation due to the airflow can be avoided. Increased coolness can be obtained.
本発明の第４の実施例について図面を用いて説明する。本実施例は、在室者からの放熱量が大きいほど在室者からの放熱量が小さくなるように（在室者からの放熱量が小さいほど在室者からの放熱量が大きくなるように）、上下風向板により在室者が位置しない方向に調和空気を向ける第１状態の運転時間に対する上下風向板をスイングさせて在室者を含む方向に一時的に調和空気を向ける第２状態の運転時間を制御するものであり、特に、運転開始からの経過時間が短いほど、第１状態の運転時間に対する第２状態の運転時間を長くする。 A fourth embodiment of the present invention will be described with reference to the drawings. In this embodiment, the greater the amount of heat radiated from the occupant, the smaller the amount of heat radiated from the occupant (the smaller the amount of heat radiated from the occupant, the greater the amount of heat radiated from the occupant. ), The conditioned air is directed in the direction in which the occupant is not located by the up-and-down wind direction plate, and the conditioned air is temporarily directed in the direction including the occupant by swinging the up-and-down wind direction plate with respect to the operation time in the first state. The operation time is controlled. In particular, the shorter the elapsed time from the start of operation, the longer the operation time in the second state relative to the operation time in the first state.
この場合、運転開始からの経過時間が短いほどスイング吹き出しの時間を長くすることができる（図１０）。例えば運転開始からの時間が１０分（例えば人が快適さに慣れる時間の２倍の１０分）以内の場合スイング吹き出しの時間を長くし（例えばスイング３回分の３０秒）、それ以降はスイング吹き出しの時間を短くする（例えばスイング１回分の１０秒）。これにより、運転開始から１０分までに十分大きな放熱量の増大により十分大きな快適感を得たあと、スイング吹き出しの時間を短くすることで寒さによる不快感の発生を防ぐことができる。 In this case, as the elapsed time from the start of operation is shorter, the swing balloon time can be lengthened (FIG. 10). For example, if the time from the start of driving is within 10 minutes (for example, 10 minutes, which is twice the time that people get used to comfort), the swing balloon time is increased (for example, 30 seconds for three swings), and thereafter the swing balloon (For example, 10 seconds for one swing). Thereby, after obtaining a sufficiently large comfort by increasing a sufficiently large heat radiation amount from the start of operation to 10 minutes, it is possible to prevent unpleasant sensation due to cold by shortening the swing blowing time.
一方、運転開始からの経過時間が短いほど定位置吹き出しの時間を短くすることができる（図１１）。例えば運転開始からの時間が１０分（例えば人が快適さに慣れる時間の２倍の１０分）以内の場合定位置吹き出しの時間を短くし（例えば人が快適さに慣れるまでの時間の５分）、それ以降は定位置吹き出しの時間を長くする（例えば人が快適さに慣れる時間の２倍の１０分）。これにより、運転開始から１０分までに十分大きな放熱量の増大により十分大きな快適感を得たあと、定位置吹き出しの時間を長くすることで寒さによる不快感の発生を防ぐことができる。 On the other hand, the shorter the elapsed time from the start of operation, the shorter the time for blowing out the fixed position (FIG. 11). For example, when the time from the start of driving is within 10 minutes (for example, 10 minutes which is twice as long as the person gets used to comfort), the time for blowing out the fixed position is shortened (for example, 5 minutes before the person gets used to comfort) After that, the time for blowing out the fixed position is lengthened (for example, 10 minutes which is twice the time when the person gets used to comfort). Thereby, after obtaining a sufficiently large comfort by increasing the heat radiation amount sufficiently large by 10 minutes from the start of operation, it is possible to prevent the discomfort caused by the cold by lengthening the time for blowing out the fixed position.
尚、本実施例における「運転開始からの経過時間」とは、空気調和機の運転開始からの経過時間であっても、暖房、冷房、除湿などの各々の運転モードでの運転開始からの経過時間であっても、断続スイング運転での運転開始からの経過時間であってもよい。 Note that the “elapsed time from the start of operation” in this embodiment is the elapsed time from the start of operation in each operation mode such as heating, cooling, and dehumidification, even if it is the elapsed time from the start of operation of the air conditioner. Even the time may be an elapsed time from the start of operation in the intermittent swing operation.
本発明の第５の実施例について図面を用いて説明する。本実施例は、在室者からの放熱量が大きいほど在室者からの放熱量が小さくなるように（在室者からの放熱量が小さいほど在室者からの放熱量が大きくなるように）、上下風向板により在室者が位置しない方向に調和空気を向ける第１状態の運転時間に対する上下風向板をスイングさせて在室者を含む方向に一時的に調和空気を向ける第２状態の運転時間を制御するものであり、特に、室内の床、壁、又は、天井からの放射温度が高いほど、第１状態の運転時間に対する前記第２状態の運転時間を長くする。 A fifth embodiment of the present invention will be described with reference to the drawings. In this embodiment, the greater the amount of heat radiated from the occupant, the smaller the amount of heat radiated from the occupant (the smaller the amount of heat radiated from the occupant, the greater the amount of heat radiated from the occupant. ), The conditioned air is directed in the direction in which the occupant is not located by the up-and-down wind direction plate, and the conditioned air is temporarily directed in the direction including the occupant by swinging the up-and-down wind direction plate with respect to the operation time in the first state. The operation time is controlled, and in particular, the higher the radiation temperature from the indoor floor, wall, or ceiling, the longer the operation time in the second state with respect to the operation time in the first state.
この場合、赤外線センサにより室内の床や壁や天井の温度を測定し、その温度が高いほどスイング吹き出しの時間を長くすることができる（図１２）。例えば、壁や床や天井の温度が４０度で、壁や床や天井から人体へ放射により熱が供給される場合（（式２）におけるＱ放射、皮膚の温度はおよそ３２度）、スイング吹き出しの時間を長くし（例えばスイング３回分の３０秒）、壁や床や天井の温度が２７度で人体から壁や床や天井へ熱が供給される場合、スイング吹き出しの時間を短くする（例えばスイング１回分の１０秒）。これにより、放射温度が高い場合には放熱量の増大によりより大きな快適感を得ることができ、放射温度が低い場合にはスイング吹き出しの時間を短くすることで寒さによる不快感の発生を防ぐことができる。 In this case, the temperature of the indoor floor, wall, or ceiling is measured by the infrared sensor, and the swing blowing time can be increased as the temperature increases (FIG. 12). For example, when the temperature of a wall, floor, or ceiling is 40 degrees, and heat is supplied from the wall, floor, or ceiling to the human body by radiation (Q radiation in (Equation 2), skin temperature is about 32 degrees), swing blowing time If the temperature of the wall, floor, or ceiling is 27 degrees and heat is supplied from the human body to the wall, floor, or ceiling, shorten the swing blowout time (for example, one swing) 10 seconds). As a result, when the radiation temperature is high, a greater comfort can be obtained by increasing the amount of heat dissipation, and when the radiation temperature is low, the swing blowout time is shortened to prevent the occurrence of discomfort due to cold. Can do.
一方、赤外線センサにより室内の床や壁や天井の温度を測定し、その温度が高いほど定位置吹き出しの時間を短くすることができる（図１３）。例えば、壁や床や天井の温度が４０度で、壁や床や天井から人体へ放射により熱が供給される場合（（式２）におけるＱ放射、皮膚の温度はおよそ３２度）、定位置吹き出しの時間を短くし（例えば人が快適さに慣れるまでの時間の５分）、壁や床や天井の温度が２７度で人体から壁や床や天井へ熱が供給される場合、定位置吹き出しの時間を短くする（例えば人が快適さに慣れる時間の２倍の１０分）。これにより、放射温度が高い場合には放熱量の増大により大きな快適感を得ることができ、放射温度が低い場合には定位置吹き出しの時間を長くすることで寒さによる不快感の発生を抑制することができる。 On the other hand, the temperature of the indoor floor, wall, or ceiling is measured by the infrared sensor, and the time for blowing out the fixed position can be shortened as the temperature increases (FIG. 13). For example, when the temperature of a wall, floor, or ceiling is 40 degrees, and heat is supplied to the human body from the wall, floor, or ceiling (Q radiation in (Equation 2), skin temperature is about 32 degrees), If the time is shortened (for example, 5 minutes until the person gets used to comfort), and the temperature of the wall, floor, or ceiling is 27 degrees, and heat is supplied from the human body to the wall, floor, or ceiling, the time for blowing out the fixed position is reduced. Keep it short (eg 10 minutes, twice the time people get used to comfort). As a result, when the radiation temperature is high, a greater comfort can be obtained by increasing the amount of heat radiation, and when the radiation temperature is low, the occurrence of discomfort due to cold is suppressed by extending the time of blowing out the fixed position. be able to.
本発明の第６の実施例について図面を用いて説明する。本実施例は、在室者からの放熱量が大きいほど在室者からの放熱量が小さくなるように（在室者からの放熱量が小さいほど在室者からの放熱量が大きくなるように）、上下風向板により在室者が位置しない方向に調和空気を向ける第１状態の運転時間に対する上下風向板をスイングさせて在室者を含む方向に一時的に調和空気を向ける第２状態の運転時間を制御するものであり、特に、送風ファンの回転数が少ないほど、第１状態の運転時間に対する第２状態の運転時間を長くする。 A sixth embodiment of the present invention will be described with reference to the drawings. In this embodiment, the greater the amount of heat radiated from the occupant, the smaller the amount of heat radiated from the occupant (the smaller the amount of heat radiated from the occupant, the greater the amount of heat radiated from the occupant. ), The conditioned air is directed in the direction in which the occupant is not located by the up-and-down wind direction plate, and the conditioned air is temporarily directed in the direction including the occupant by swinging the up-and-down wind direction plate with respect to the operation time in the first state. The operation time is controlled, and in particular, the operation time in the second state with respect to the operation time in the first state is increased as the rotational speed of the blower fan is decreased.
この場合、室内ファンの回転数が少ないほどスイング吹き出しの時間を長くすることができる（図１４）。例えば、気流速度が微風の設定の場合など室内ファンの回転数が少なく気流による放熱量の少ない場合にはスイング吹き出しの時間を長くし（例えばスイング３回分の３０秒）、気流速度の設定が強風の場合など室内ファンの回転数が多い場合にはスイング吹き出しの時間を短くする（例えばスイング１回分の１０秒）。これにより、設定風速の小さい場合には気流による放熱量の増大によりより大きな快適感を得ることができ、設定風速が大きい場合には気流による放熱の増大に伴う寒さによる不快感の発生を抑制することができる。 In this case, the swing blowing time can be increased as the number of rotations of the indoor fan is reduced (FIG. 14). For example, when the airflow speed is set at a low breeze and the indoor fan is rotating at a low speed and the amount of heat released by the airflow is small, the swing blowout time is increased (for example, 30 seconds for three swings), and the airflow speed is set at a strong wind. When the number of revolutions of the indoor fan is large, such as in the case of, the swing blowing time is shortened (for example, 10 seconds for one swing). As a result, when the set wind speed is low, a greater feeling of comfort can be obtained by increasing the amount of heat released by the airflow, and when the set wind speed is high, the generation of discomfort due to the cold accompanying the increased heat dissipation by the airflow is suppressed. be able to.
一方、室内ファンの回転数が少ないほど定位置吹き出しの時間を短くすることができる（図１５）。例えば、気流速度が微風の設定の場合など室内ファンの回転数が少なく、気流による放熱量の少ない場合には定位置吹き出しの時間を短くし（例えば人が快適さに慣れるまでの時間の５分）、気流速度の設定が強風の場合など室内ファンの回転数が多い場合には定位置吹き出しの時間を長くする（例えば人が快適さに慣れる時間の２倍の１０分）。これにより、設定風速の小さい場合には気流による放熱量の増大によりより大きな快適感を得ることができ、設定風速が大きい場合には気流による放熱の増大に伴う寒さによる不快感の発生を抑制することができる。 On the other hand, as the number of rotations of the indoor fan decreases, the time for blowing out the fixed position can be shortened (FIG. 15). For example, when the rotational speed of the indoor fan is low, such as when the airflow speed is set at a low breeze, and the amount of heat released by the airflow is small, the time for blowing out the fixed position is shortened (for example, 5 minutes until the person gets used to comfort). ) When the rotational speed of the indoor fan is high, such as when the airflow speed is set to a strong wind, the time for blowing out the fixed position is lengthened (for example, 10 minutes which is twice the time when a person gets used to comfort). As a result, when the set wind speed is low, a greater feeling of comfort can be obtained by increasing the amount of heat released by the airflow, and when the set wind speed is high, the generation of discomfort due to the cold accompanying the increased heat dissipation by the airflow is suppressed. be able to.
しかしながら、上記とは反対に、在室者からの放熱量とは関係なく、室内ファンの回転数が多いほどスイング吹き出しの時間を長くしてもよい。これにより、室内ファンの回転数が多くユーザが気流による放熱をより多く求めている場合にはスイング吹き出しの時間を長くし（例えばスイング３回分の３０秒）、室内ファンの回転数が少なくユーザが気流による放熱の促進を求めていない場合にはスイング吹き出しの時間を短くする（例えばスイング１回分の１０秒）ことで、ユーザの要求をより進めた温熱環境を提供することができる。また、同様に、室内ファンの回転数が多いほど定位置吹き出しの時間を長くしてもよい。これにより、室内ファンの回転数が多くユーザが気流による放熱をより多く求めている場合には定位置吹き出しの時間を短くし（例えば人が快適さに慣れるまでの時間の５分）、室内ファンの回転数が少なくユーザが気流による放熱の促進を求めていない場合には定位置吹き出しの時間を長くする（例えば人が快適さに慣れる時間の２倍の１０分）ことで、ユーザの要求をより進めた温熱環境を提供することができる。 However, contrary to the above, regardless of the amount of heat released from the occupants, the swing blowing time may be lengthened as the number of rotations of the indoor fan increases. As a result, when the number of rotations of the indoor fan is large and the user demands more heat radiation by the airflow, the swing blowout time is lengthened (for example, 30 seconds for three swings), and the number of rotations of the indoor fan is small. When the promotion of heat dissipation by the airflow is not required, the thermal environment where the user's request is further advanced can be provided by shortening the swing blowing time (for example, 10 seconds for one swing). Similarly, the time for blowing out the fixed position may be increased as the number of rotations of the indoor fan increases. As a result, when the number of rotations of the indoor fan is large and the user is demanding more heat radiation by the airflow, the time for blowing out the fixed position is shortened (for example, 5 minutes until the person gets used to comfort), and the indoor fan If the number of rotations is low and the user does not seek to promote heat dissipation by airflow, the time required for blowing out the fixed position is increased (for example, 10 minutes, twice the time for people to get used to comfort). A more advanced thermal environment can be provided.
本発明の第７の実施例について図面を用いて説明する。本実施例は、在室者からの放熱量が大きいほど在室者からの放熱量が小さくなるように（在室者からの放熱量が小さいほど在室者からの放熱量が大きくなるように）、上下風向板により在室者が位置しない方向に調和空気を向ける第１状態の運転時間に対する上下風向板をスイングさせて在室者を含む方向に一時的に調和空気を向ける第２状態の運転時間を制御するものであり、特に、室外の気温が高いほど、第１状態の運転時間に対する第２状態の運転時間を長くする。 A seventh embodiment of the present invention will be described with reference to the drawings. In this embodiment, the greater the amount of heat radiated from the occupant, the smaller the amount of heat radiated from the occupant (the smaller the amount of heat radiated from the occupant, the greater the amount of heat radiated from the occupant. ), The conditioned air is directed in the direction in which the occupant is not located by the up-and-down wind direction plate, and the conditioned air is temporarily directed in the direction including the occupant by swinging the up-and-down wind direction plate with respect to the operation time in the first state. The operation time is controlled. In particular, the higher the outdoor temperature, the longer the operation time in the second state with respect to the operation time in the first state.
この場合、外気温度が高いほどスイング吹き出しの時間を長くすることができる（図１６）。例えば、外気温度が４０度の場合ではスイング吹き出しの時間を長くし（例えばスイング３回分の３０秒）、外気温度が３０度の場合ではスイング吹き出しの時間を短くする（例えばスイング１回分の１０秒）。これにより、高い外気温の熱が壁や床や天井を貫通して放射や伝導による人体からの放熱が小さくなる（（式２）におけるＱ放射とＱ伝導が小さくなる）場合に、気流により放熱量を増大させ（（式１）においてαを大きくすることによりＱを大きくさせる）、涼しさによる快適感を得ることができる。また、外気温度が低い場合には、放射や伝導による放熱量が大きいため、対流による放熱を低くすることで寒さによる不快感を防ぐことができる。 In this case, as the outside air temperature is higher, the swing blowing time can be lengthened (FIG. 16). For example, when the outside air temperature is 40 degrees, the swing blowing time is increased (for example, 30 seconds for three swings), and when the outside temperature is 30 degrees, the swing blowing time is shortened (for example, 10 seconds for one swing). ). As a result, when the heat of high outside air temperature penetrates the walls, floors, and ceilings and the heat dissipation from the human body due to radiation and conduction becomes small (Q radiation and Q conduction in (Equation 2) become small), the amount of heat released by the airflow Can be increased (by increasing α in (Equation 1), Q can be increased), and a comfortable feeling due to coolness can be obtained. In addition, when the outside air temperature is low, the amount of heat released by radiation or conduction is large, so that discomfort due to cold can be prevented by reducing the heat released by convection.
一方、外気温度が高いほど定位置吹き出しの時間を短くすることができる（図１７）。例えば、外気温度が４０度の場合では定位置吹き出しの時間を短くし（例えば人が快適さに慣れるまでの時間の５分）、外気温度が３０度の場合では定位置吹き出しの時間を長くする（例えば人が快適さに慣れる時間の２倍の１０分）。これにより、高い外気温の熱が壁や床や天井を貫通して放射や伝導による人体からの放熱が小さくなる（（式２）におけるＱ放射とＱ伝導が小さくなる）場合に気流により放熱量を増大させ（（式１）においてαを大きくすることによりＱを大きくさせる）涼しさによる快適感を得ることができる。また、外気温度が低い場合には、放射や伝導による放熱量が大きいため、対流による放熱を低くすることで寒さによる不快感を防ぐことができる。 On the other hand, the higher the outside air temperature, the shorter the time for blowing out the fixed position (FIG. 17). For example, when the outside air temperature is 40 degrees, the time for blowing out the fixed position is shortened (for example, 5 minutes until the person gets used to comfort), and when the outside temperature is 30 degrees, the time for blowing out the fixed position is lengthened. (For example, 10 minutes, twice the time people get used to comfort). As a result, when the heat of high outside air temperature penetrates the walls, floors and ceilings and the heat radiation from the human body due to radiation and conduction becomes small (Q radiation and Q conduction in (Equation 2) become small), the heat radiation is reduced by the air flow. A feeling of comfort due to coolness can be obtained by increasing (increasing Q by increasing α in (Expression 1)). In addition, when the outside air temperature is low, the amount of heat released by radiation or conduction is large, so that discomfort due to cold can be prevented by reducing the heat released by convection.
本発明の第８の実施例について図面を用いて説明する。本実施例は、在室者からの放熱量が大きいほど在室者からの放熱量が小さくなるように（在室者からの放熱量が小さいほど在室者からの放熱量が大きくなるように）、上下風向板により在室者が位置しない方向に調和空気を向ける第１状態の運転時間に対する上下風向板をスイングさせて在室者を含む方向に一時的に調和空気を向ける第２状態の運転時間を制御するものであり、特に、設定温度が高いほど、第１状態の運転時間に対する第２状態の運転時間を長くする。 An eighth embodiment of the present invention will be described with reference to the drawings. In this embodiment, the greater the amount of heat radiated from the occupant, the smaller the amount of heat radiated from the occupant (the smaller the amount of heat radiated from the occupant, the greater the amount of heat radiated from the occupant. ), The conditioned air is directed in the direction in which the occupant is not located by the up-and-down wind direction plate, and the conditioned air is temporarily directed in the direction including the occupant by swinging the up-and-down wind direction plate with respect to the operation time in the first state. The operation time is controlled. In particular, the higher the set temperature, the longer the operation time in the second state relative to the operation time in the first state.
この場合、設定温度が高いほどスイング吹き出しの時間を長くすることができる（図１８）。例えば、設定温度が２９度の場合ではスイング吹き出の時間を長くし（例えばスイング３回分の３０秒）、設定温度が２５度の場合ではスイング吹き出しの時間を短くする（例えばスイング１回分の１０秒）。これにより、設定室温が高く人体からの放熱が少ない場合には気流により人体からの放熱量を増やし涼しさによる快適を感じることができ、設定室温が低く人体からの放熱が多い場合には気流による放熱の増大を小さくし寒さによる不快感を防ぐことができる。 In this case, the swing blowing time can be lengthened as the set temperature is higher (FIG. 18). For example, when the set temperature is 29 degrees, the swing blowing time is lengthened (for example, 30 seconds for three swings), and when the set temperature is 25 degrees, the swing blowing time is shortened (for example, 10 seconds for one swing). ). As a result, when the set room temperature is high and the heat dissipation from the human body is low, the amount of heat released from the human body can be increased by the airflow, and the comfort due to the coolness can be felt, and when the set room temperature is low and the heat dissipation from the human body is large, the airflow Increase in heat dissipation can be reduced to prevent discomfort due to cold.
一方、設定温度が高いほど定位置吹き出しの時間を短くすることができる（図１９）。例えば、設定温度が２９度の場合では定位置吹き出の時間を短くし（例えば人が快適さに慣れるまでの時間の５分）、設定温度が２５度の場合では定位置吹き出しの時間を長くする（例えば人が快適さに慣れる時間の２倍の１０分）。これにより、設定室温が高く人体からの放熱が少ない場合には気流により人体からの放熱量を増やし涼しさによる快適を感じることが可能となり、設定室温が低く人体からの放熱が多い場合には気流による放熱の増大を小さくし寒さによる不快感を防ぐことができる。 On the other hand, the higher the set temperature, the shorter the time for blowing out the fixed position (FIG. 19). For example, when the set temperature is 29 degrees, the time for blowing out the fixed position is shortened (for example, 5 minutes until the person gets used to comfort), and when the set temperature is 25 degrees, the time for blowing out the fixed position is lengthened. (For example, 10 minutes, twice the time people get used to comfort). As a result, when the set room temperature is high and there is little heat dissipation from the human body, it is possible to feel the comfort due to cooling by increasing the heat dissipation from the human body, and when the set room temperature is low and the heat dissipation from the human body is high It is possible to reduce the increase in heat dissipation due to the cold and to prevent discomfort due to cold.
本発明の第９の実施例について図面を用いて説明する。本実施例は、在室者からの放熱量が大きいほど在室者からの放熱量が小さくなるように（在室者からの放熱量が小さいほど在室者からの放熱量が大きくなるように）、上下風向板により在室者が位置しない方向に調和空気を向ける第１状態の運転時間に対する上下風向板をスイングさせて在室者を含む方向に一時的に調和空気を向ける第２状態の運転時間を制御するものであり、特に、室内の温度が高いほど、第１状態の運転時間に対する第２状態の運転時間を長くする。 A ninth embodiment of the present invention will be described with reference to the drawings. In this embodiment, the greater the amount of heat radiated from the occupant, the smaller the amount of heat radiated from the occupant (the smaller the amount of heat radiated from the occupant, the greater the amount of heat radiated from the occupant. ), The conditioned air is directed in the direction in which the occupant is not located by the up-and-down wind direction plate, and the conditioned air is temporarily directed in the direction including the occupant by swinging the up-and-down wind direction plate with respect to the operation time in the first state. The operation time is controlled. In particular, the higher the indoor temperature, the longer the operation time in the second state with respect to the operation time in the first state.
この場合、室温が高いほどスイング吹き出しの時間を長くすることができる（図２０）。例えば、室温が２９度の場合ではスイング吹き出しの時間を短くし（例えばスイング１回分の１０秒）、室温が３５度の方が、スイング吹き出しの時間を長くする（例えばスイング３回分の３０秒）。これにより、生活空間の温度が低く放熱量が大きい（ＴＳの低さによるＱの増大）場合には気流による放熱量の増大量を減らし（αを小さくしてＱの増大を低くする）、生活空間の温度が高く放熱量が小さい場合には気流による放熱量の増大量を増やすことで、室温が低い場合には気流による放熱量の増大による寒さの不快感を避けることができ、また室温が高い場合には気流による放熱量の増大で涼しさを得ることができる。 In this case, the longer the room temperature, the longer the swing blowing time (FIG. 20). For example, when the room temperature is 29 degrees, the swing balloon time is shortened (for example, 10 seconds for one swing), and when the room temperature is 35 degrees, the swing balloon time is lengthened (for example, 30 seconds for three swings). . As a result, when the living space temperature is low and the amount of heat released is large (increase in Q due to the low TS), the amount of increase in the amount of heat released by the airflow is reduced (by reducing α to reduce the increase in Q), When the temperature of the space is high and the amount of heat released is small, the amount of increase in the amount of heat released by the airflow can be increased, and when the room temperature is low, the discomfort of the cold caused by the increase in the amount of heat released by the airflow can be avoided. When it is high, coolness can be obtained by increasing the amount of heat released by the airflow.
一方、室温が低いほど定位置吹き出しの時間を長くすることができる（図２１）。例えば、室温が２９度の場合では定位置吹き出しの時間を長くし（例えば人が快適さに慣れる時間の２倍の１０分）、室温が３５度の方が、定位置吹き出しの時間を長くする（例えば人が快適さに慣れる時間の５分）。これにより、生活空間の温度が低く放熱量が大きい（ＴＳの低さによるＱの増大）場合には気流による放熱量の増大量を減らし（αを小さくしてＱの増大を低くする）、生活空間の温度が高く放熱量が小さい場合には気流による放熱量の増大量を増やすことで、室温が低い場合には気流による放熱量の増大による寒さの不快感を避けることができ、また室温が高い場合には気流による放熱量の増大で涼しさを得ることができる。 On the other hand, as the room temperature is lower, the time for blowing out the fixed position can be lengthened (FIG. 21). For example, when the room temperature is 29 degrees, the time for blowing out the fixed position is increased (for example, 10 minutes, twice as long as the time when the person gets used to comfort), and when the room temperature is 35 degrees, the time for blowing out the fixed position is increased. (For example, 5 minutes of time for people to get used to comfort). As a result, when the living space temperature is low and the amount of heat released is large (increase in Q due to the low TS), the amount of increase in the amount of heat released by the airflow is reduced (by reducing α to reduce the increase in Q), When the temperature of the space is high and the amount of heat released is small, the amount of increase in the amount of heat released by the airflow can be increased, and when the room temperature is low, the discomfort of the cold caused by the increase in the amount of heat released by the airflow can be avoided. When it is high, coolness can be obtained by increasing the amount of heat released by the airflow.
上記各実施例においては、ユーザがスイング吹き出しの時間に関わらない場合について説明した。しかし、本発明はこれに限定されるものではない。 In each of the above-described embodiments, the case where the user is not involved in the swing balloon time has been described. However, the present invention is not limited to this.
例えば、初期の設定に加え、ユーザがスイング吹き出しの時間をリモコンで設定する制御としてもよい。これにより、スイング吹き出しの時間の初期の設定（例えばスイング１回分の１０秒）での運転時に、ユーザが気流による放熱の増大を求めた場合、スイング吹き出しの時間が長くなるよう（例えばスイング３回分の３０秒）リモコンで設定することができ、ユーザの好みに合わせた温熱環境を提供することができる。また、スイング吹き出しの時間の初期の設定（例えばスイング３回分の３０秒）での運転時にユーザが気流による放熱の増大による寒さを感じた場合、スイング吹き出しの時間を短く（例えばスイング１回分の１０秒）することで、ユーザにとってより快適な温熱環境を提供することができる。 For example, in addition to the initial setting, the user may set the swing balloon time with a remote controller. Thus, when the user requests an increase in heat dissipation due to the airflow during operation with the initial setting of the swing balloon time (for example, 10 seconds for one swing), the swing balloon time is increased (for example, for three swings). 30 seconds) can be set with a remote controller, and a thermal environment can be provided according to the user's preference. In addition, when the user feels cold due to an increase in heat dissipation due to the airflow during operation with the initial setting of the swing blowing time (for example, 30 seconds for three swings), the swing blowing time is shortened (for example, 10 times for one swing). Seconds), it is possible to provide a more comfortable thermal environment for the user.
また、初期の設定に加え、ユーザが定位置吹き出しの時間をリモコンで設定する制御としてもよい。これにより、定位置吹き出しの時間の初期の設定（例えば人が快適さに慣れる時間の２倍の１０分）での運転時に、ユーザが気流による放熱の増大を求めた場合、定位置吹き出しの時間が短くなるよう（例えば人が快適さに慣れる時間の５分）リモコンで設定することができ、ユーザの好みに合わせた温熱環境を提供することができる。また、定位置吹き出しの時間の初期の設定（例えば人が快適さに慣れる時間の５分）での運転時にユーザが気流による放熱の増大による寒さを感じた場合、定位置吹き出しの時間を長く（例えば人が快適さに慣れる時間の２倍の１０分）することで、ユーザにとってより快適な温熱環境を提供することができる。 In addition to the initial setting, the user may set the time for blowing out the fixed position with a remote controller. Thus, when the user asks for an increase in heat dissipation due to the airflow during operation at the initial setting of the time for blowing out the fixed position (for example, 10 minutes which is twice the time when the person gets used to comfort), Can be set with a remote control so that the temperature becomes shorter (for example, 5 minutes when a person gets used to comfort), and a thermal environment according to the user's preference can be provided. Also, if the user feels cold due to an increase in heat dissipation due to the airflow when driving at the initial setting of the fixed position balloon time (for example, 5 minutes when the person gets used to comfort), the fixed position balloon time is increased ( For example, it is possible to provide a more comfortable thermal environment for the user by taking 10 minutes, which is twice the time when a person gets used to comfort.
上記各実施例においては、設定室温と室温との差、運転開始からの時間、床などの物体の表面温度センサ、室内ファンの回転数、外気温度、設定温度、室温を２段階に分けて、スイング吹き出しの時間又は定位置吹き出しの時間が異なる場合について説明した。しかし、本発明はこれに限定されるものではない。例えば、設定室温と室温との差に応じてスイング吹き出しの時間又は定位置吹き出しの時間を変化させる場合には、設定室温と室温との差を１度ピッチでその差に比例して吹き出し時間を増減させてもよい（図２２）。 In each of the above embodiments, the difference between the set room temperature and the room temperature, the time from the start of operation, the surface temperature sensor of the object such as the floor, the rotational speed of the indoor fan, the outside air temperature, the set temperature, and the room temperature are divided into two stages, The case where the swing balloon time or the fixed position balloon time is different has been described. However, the present invention is not limited to this. For example, when changing the swing blowing time or the fixed position blowing time in accordance with the difference between the set room temperature and the room temperature, the difference between the set room temperature and the room temperature is set to a pitch once in proportion to the difference. You may increase / decrease (FIG. 22).
また、設定室温と室温との差と指数関数や対数関数、ｎ次関数のような曲線の関係で吹き出し時間を増減させてもよい（図２３）。 Further, the blowing time may be increased or decreased depending on the relationship between the difference between the set room temperature and the room temperature and a curve such as an exponential function, logarithmic function, or n-order function (FIG. 23).
また、設定室温と室温との差に、ステップ変化で吹き出し時間を増減させてもよい（例えば図１０）。 Further, the blowing time may be increased or decreased by a step change to the difference between the set room temperature and the room temperature (for example, FIG. 10).
また、設定室温と室温との差にランプ変化で吹き出し時間を増減させてもよい（図２４）。 Further, the blowing time may be increased or decreased by changing the lamp to the difference between the set room temperature and room temperature (FIG. 24).
さらに、スイング吹き出しの時間及び定位置吹き出しの時間は、上記各実施例で例として挙げた値に限定されるものではなく、ＳＥＴやＰＭＶといった温熱環境評価指標に基づく値や、実験に基づく値、ウェーバー比、独自の基準で決めた値などであっても良い。 Further, the swing blowing time and the fixed position blowing time are not limited to the values given as examples in each of the above embodiments, but values based on thermal environment evaluation indices such as SET and PMV, values based on experiments, It may be a Weber ratio, a value determined by an original standard, or the like.
さらに、スイング吹き出しの時間及び定位置吹き出しの時間は、上記各実施例で例として挙げた値に限定されるものではなく、経時的に増減しても良い。 Furthermore, the swing balloon time and the fixed position balloon time are not limited to the values given as examples in the above embodiments, and may be increased or decreased over time.
