Description

本発明は、空調対象室を冷房又は暖房する空調機と、空調対象室の計測室内温度に基づいて前記空調機の出力を調整することで空調対象室の室内温度を設定室内温度に調整する制御手段とを備える空調制御システムに関する。 The present invention provides an air conditioner that cools or heats an air-conditioning target room, and a control that adjusts the room temperature of the air-conditioning target room to a set room temperature by adjusting the output of the air conditioner based on the measured indoor temperature of the air-conditioning target room. And an air conditioning control system.

従来、この種の空調制御システムでは、空調機の出力を調整する制御手段に対して設定する設定室内温度を空調対象室の室内者や管理者等が設定器により適宜に設定変更することで、空調対象室の室内空調状態を調整（略言すれば、空調の強弱を調整）するようにしていた。 Conventionally, in this type of air conditioning control system, an indoor person or an administrator of the air-conditioning target room appropriately sets and changes the setting room temperature set for the control means for adjusting the output of the air conditioner, The indoor air-conditioning state of the air-conditioning target room is adjusted (in short, the strength of the air-conditioning is adjusted).

しかし、空調対象室における室内者の体感温度は、放射温度、室内温度、室内気流速度等々の種々の要因によって変化することから、室内者の体感温度と空調対象室の室内温度とは一致せず、この為、設定室内温度を人為的に設定変更する上記システムでは、所望の体感温度が得られる良好な室内空調状態を得ようとすると、設定室内温度を試行錯誤的に設定変更しなければならず、この点で室内空調状態の調整が難しく、また、煩わしい問題があった。 However, the sensible temperature of the indoor person in the air conditioned room varies depending on various factors such as the radiation temperature, the room temperature, the indoor air velocity, etc., so the sensible temperature of the indoor person does not match the room temperature of the air conditioned room. For this reason, in the above-described system for artificially changing the set room temperature, the set room temperature must be changed by trial and error in order to obtain a favorable indoor air-conditioning state in which the desired temperature can be obtained. In this respect, it is difficult to adjust the indoor air-conditioning state, and there is a troublesome problem.

そして、この問題を解消するのに、下記の特許文献１では、体感温度＝（室内温度＋床や壁からの輻射温度）／２という簡易な体感温度相関式に着目して、この体感温度相関式に輻射センサにより計測される床や壁からの輻射温度と所望の体感温度とを代入する演算形態で、所望の体感温度が得られる室内温度を演算し、この演算室内温度を設定室内温度として設定することで、所望の体感温度を得るようにした体感温度基準の空調制御システムが提案されている（特に、特許文献１における[００３２]〜［００３４］の実施の形態５を参照）。 In order to solve this problem, in the following Patent Document 1, paying attention to a simple sensory temperature correlation equation: sensory temperature = (indoor temperature + radiation temperature from floor or wall) / 2, this sensory temperature correlation formula The calculation is made by substituting the radiation temperature from the floor or wall measured by the radiation sensor and the desired sensory temperature, and the indoor temperature at which the desired sensory temperature is obtained is calculated, and this calculated indoor temperature is set as the set indoor temperature. Thus, an air temperature control system based on the temperature of sensation that can obtain a desired temperature of sensation has been proposed (in particular, refer to Embodiment 5 of [0032] to [0034] in Patent Document 1).

特開２００４−２８４５０JP2004-28450

しかし、特許文献１の上記提案システムでは、室内温度を計測する室内温度センサに加えて、床や壁からの輻射温度を計測する輻射センサ（あるいは床や各壁の温度夫々を計測する温度センサ）が必要になり、この為、システム構成が複雑になるとともにシステムコストが嵩む問題がある。 However, in the proposed system of Patent Document 1, in addition to the indoor temperature sensor that measures the indoor temperature, a radiation sensor that measures the radiation temperature from the floor and walls (or a temperature sensor that measures the temperature of each floor and each wall) is required. Therefore, there is a problem that the system configuration becomes complicated and the system cost increases.

この実情に鑑み、本発明の主たる課題は、所望の体感温度を得る体感温度基準の室内空調を簡易なシステム構成で安価に実現する点にある。 In view of this situation, the main object of the present invention is to realize low-temperature indoor air-conditioning based on a sensible temperature to obtain a desired sensible temperature with a simple system configuration.

本発明の第１特徴構成は、空調制御システムに係り、その特徴は、
空調対象室を冷房又は暖房する空調機と、空調対象室の計測室内温度に基づいて前記空調機の出力を調整することで空調対象室の室内温度を設定室内温度に調整する制御手段とを備える空調制御システムであって、
前記制御手段は、平均放射温度を演算する放射温度演算式のパラメータである室内表面温度として空調対象室の計測室内温度を前記放射温度演算式に代入する演算形態で、空調対象室の平均放射温度を演算する放射温度演算ステップと、
室内温度と平均放射温度と体感温度との相関を表す体感温度相関式のパラメータである平均放射温度及び体感温度として、前記放射温度演算ステップで演算した演算平均放射温度及び設定手段により設定された設定体感温度を、前記体感温度相関式に代入する演算形態で、前記体感温度相関式のパラメータである室内温度を演算する室内温度演算ステップと、
この室内温度演算ステップで演算した演算室内温度を、空調対象室において前記設定体感温度を得るための前記設定室内温度として設定する設定ステップとを実行する構成にしてあり、
前記制御手段は、前記放射温度演算ステップにおいて、空調対象室の計測室内温度を壁用の前記室内表面温度として前記放射温度演算式に代入し、かつ、計測外気温度を窓用の前記室内表面温度として前記放射温度演算式に代入する演算形態で、空調対象室の平均放射温度を演算する構成にしてある点にある。 The first characteristic configuration of the present invention relates to an air conditioning control system,
An air conditioner that cools or heats the air-conditioning target room, and a control unit that adjusts the room temperature of the air-conditioning target room to the set room temperature by adjusting the output of the air-conditioning unit based on the measured indoor temperature of the air-conditioning target room. An air conditioning control system,
The control means is an arithmetic mode in which the measured room temperature of the air-conditioning target room is substituted into the radiation temperature calculating formula as the indoor surface temperature that is a parameter of the radiation temperature calculating formula for calculating the average radiation temperature. Radiation temperature calculation step for calculating
The average radiant temperature and the sensation temperature, which are parameters of the sensation temperature correlation equation representing the correlation between the room temperature, the average radiant temperature, and the sensation temperature, are the average radiant temperature calculated in the radiant temperature calculation step and the setting set by the setting means An indoor temperature calculation step of calculating a room temperature that is a parameter of the body temperature correlation equation in a calculation form that substitutes the body temperature with the body temperature correlation equation;
The operation room temperature computed in this room temperature operational step, Ri Thea a configuration for executing a setting step of setting as the setting indoor temperature to obtain the set effective temperature in the air-conditioning target chamber,
In the radiation temperature calculation step, the control means substitutes the measured indoor temperature of the air-conditioning target room as the indoor surface temperature for the wall into the radiation temperature calculation formula, and the measured outside air temperature as the indoor surface temperature for the window. In the calculation form substituted for the radiation temperature calculation formula, the average radiation temperature of the air-conditioning target room is calculated .

この構成では、放射温度演算ステップで演算した演算平均放射温度、及び、設定手段により設定された設定体感温度を体感温度相関式に代入する演算形態で、体感温度相関式のパラメータである室内温度を演算し、この演算室内温度を設定室内温度として設定することにより、計測室内温度に基づき空調機出力を調整して室内温度を設定室内温度に調整する元々の室内温度制御を利用して、設定体感温度が得られる室内空調状態を現出する。 In this configuration, the calculation average radiation temperature calculated in the radiation temperature calculation step and the set sensory temperature set by the setting means are substituted into the sensory temperature correlation equation, and the room temperature, which is a parameter of the sensory temperature correlation equation, is calculated. By calculating and setting this calculated room temperature as the set room temperature, the setting experience is adjusted using the original room temperature control that adjusts the air conditioner output based on the measured room temperature and adjusts the room temperature to the set room temperature. Appears indoor air-conditioning conditions where temperature can be obtained.

そして、放射温度演算ステップでは、上記の室内温度制御に元々必要な空調対象室の計測室内温度を放射温度演算式のパラメータである室内表面温度として放射温度演算式に代入する演算形態で、空調対象室の平均放射温度を演算するから、室内表面からの輻射温度を計測する輻射センサや、各室内表面の温度夫々を計測する温度センサの装備が不要になる。 In the radiation temperature calculation step, the measured room temperature of the air conditioning target room originally required for the indoor temperature control is substituted into the radiation temperature calculation formula as the room surface temperature that is a parameter of the radiation temperature calculation formula. Since the average radiation temperature of the room is calculated, it is not necessary to provide a radiation sensor for measuring the radiation temperature from the indoor surface and a temperature sensor for measuring the temperature of each indoor surface.

したがって、上記構成によれば、設定室内温度を人為的に設定していた前述の従来システムに比べ、所望の体感温度が安定的に得られる快適性に優れた体感温度基準の室内空調を簡便に実現することができる。 Therefore, according to the above-described configuration, compared with the above-described conventional system in which the set room temperature is set artificially, the room temperature air conditioning based on the sensory temperature reference, which is excellent in comfort and can stably obtain a desired sensory temperature, can be easily performed. Can be realized.

また、前述の特許文献１の提案システムに比べれば、室内表面からの輻射温度を計測する輻射センサや、各室内表面の温度夫々を計測する温度センサの追加装備が不要になることで、その分、システム構成を簡易にするとともにシステムコストを安価にしながら、体感温度基準の空調を実現することができる。 Further, compared with the proposed system of Patent Document 1 described above, additional equipment such as a radiation sensor for measuring the radiation temperature from the indoor surface and a temperature sensor for measuring the temperature of each indoor surface is not required. Therefore, it is possible to realize air conditioning based on the sensible temperature while simplifying the system configuration and reducing the system cost.

なお、この構成の実施において、平均放射温度を演算する放射温度演算式としては、例えば、次の式１に代表されるような一般的な放射温度演算式を採用すればよい。 In the implementation of this configuration, as a radiation temperature calculation expression for calculating the average radiation temperature, for example, a general radiation temperature calculation expression represented by the following Expression 1 may be adopted.

また、室内温度と平均放射温度と体感温度との相関を表す体感温度相関式としては、例えば、次の式２（べドフォードの等価温度算出式）に代表されるような一般的な体感温度相関式を採用すればよい。 In addition, as a body temperature correlation expression representing the correlation between the room temperature, the average radiation temperature, and the body temperature, for example, a general body temperature represented by the following formula 2 (Bedford's equivalent temperature calculation formula) A correlation equation may be employed.

さらに、放射温度演算ステップにおいて、空調対象室の計測室内温度を室内表面温度として放射温度演算式（例えば、式１）に代入する演算形態で、空調対象室の平均放射温度を演算するにあたっては、計測室内温度をそのまま室内表面温度として放射温度演算式に代入する演算形態に限らず、計測室内温度に種々の補正を施した補正室内温度を室内表面温度として放射温度演算式に代入する演算形態を採用してもよい。 Further, in the radiation temperature calculation step, in calculating the average radiation temperature of the air-conditioning target room in a calculation form in which the measured room temperature of the air-conditioning target room is substituted into the radiation temperature calculation formula (for example, Formula 1) as the room surface temperature, The calculation mode is not limited to the calculation mode in which the measured room temperature is directly substituted into the radiation temperature calculation formula as the room surface temperature, but the calculation mode in which the corrected room temperature obtained by performing various corrections on the measurement room temperature is substituted into the radiation temperature calculation formula as the room surface temperature. It may be adopted.

例えば、計測室内温度と実際の室内表面温度との温度差を検証し、この温度差分だけ計測室内温度を補正した差分補正室内温度を室内表面温度として放射温度演算式に代入する演算形態を採るなどしてもよい。 For example, the temperature difference between the measured indoor temperature and the actual indoor surface temperature is verified, and a calculation form is adopted in which the difference corrected indoor temperature obtained by correcting the measured indoor temperature by this temperature difference is substituted into the radiation temperature calculation formula as the indoor surface temperature. May be.

また、本発明の第１特徴構成では、
前記制御手段は、前記放射温度演算ステップにおいて、空調対象室の計測室内温度を壁用の前記室内表面温度として前記放射温度演算式に代入し、かつ、計測外気温度を窓用の前記室内表面温度として前記放射温度演算式に代入する演算形態で、空調対象室の平均放射温度を演算する構成にしてある。 In the first characteristic configuration of the present invention,
In the radiation temperature calculation step, the control means substitutes the measured indoor temperature of the air-conditioning target room as the indoor surface temperature for the wall into the radiation temperature calculation formula, and the measured outside air temperature as the indoor surface temperature for the window. wherein the arithmetic form by substituting the radiation temperature arithmetic expression, are a configuration that calculates the average radiation temperature of the air-conditioning target chamber as.

つまり、窓以外（例えば非冷却・非加熱の壁や床）の室内表面温度は室内温度に依存する傾向が強いが、窓の室内表面温度については、一般的に、室内温度に依存するよりも外気温度に依存する傾向の方が強い。 In other words, the indoor surface temperature of windows other than windows (for example, non-cooled / non-heated walls and floors) tends to depend on the indoor temperature, but the indoor surface temperature of windows generally does not depend on the indoor temperature. The tendency to depend on the outside temperature is stronger.

したがって、放射温度演算ステップにおいて、計測室内温度を壁用の室内表面温度として放射温度演算式に代入し、かつ、計測外気温度を窓用の室内表面温度として放射温度演算式に代入する演算形態で空調対象室の平均放射温度を演算する上記構成によれば、空調対象室の平均放射温度として、実際の平均放射温度により近い一層正確な平均放射温度を演算することができ、これにより、室内温度演算ステップで演算する室内温度も一層正確なものにすることができて、実際に得られる体感温度と設定体感温度との誤差がより小さい一層優れた体感温度基準の室内空調を実現することができる。 Therefore, in the radiation temperature calculation step, the measurement room temperature is substituted into the radiation temperature calculation formula as the wall indoor surface temperature, and the measurement outside air temperature is substituted into the radiation temperature calculation formula as the window indoor surface temperature. According to the above configuration for calculating the average radiation temperature of the air-conditioning target room, it is possible to calculate a more accurate average radiation temperature closer to the actual average radiation temperature as the average radiation temperature of the air-conditioning target room. The room temperature calculated in the calculation step can also be made more accurate, and it is possible to realize an even better room temperature air conditioning with a smaller error between the actually obtained temperature and the set temperature. .

なお、この構成の実施において、空調対象室の計測室内温度を壁用の室内表面温度として放射温度演算式に代入し、かつ、計測外気温度を窓用の室内表面温度として放射温度演算式に代入する演算形態で、空調対象室の平均放射温度を演算するにあたっては、計測室内温度をそのまま壁用の室内表面温度として放射温度演算式に代入し、かつ、計測外気温度をそのまま窓用の室内表面温度として放射温度演算式に代入する演算形態に限らず、計測室内温度に種々の補正を施した補正室内温度を壁用の室内表面温度として放射温度演算式に代入したり、計測外気温度に種々の補正を施した補正外気温度を窓用の室内表面温度として放射温度演算式に代入する演算形態を採用してもよい。 In the implementation of this configuration, the measured room temperature of the air-conditioning target room is substituted into the radiation temperature calculation formula as the wall surface temperature for the wall, and the measured outside air temperature is substituted into the radiation temperature calculation formula as the room temperature for the window. When calculating the average radiant temperature of the air-conditioned room in this calculation mode, the measured room temperature is directly substituted into the radiation temperature calculation formula as the wall surface temperature for the wall, and the measured outside air temperature is directly used as the indoor surface for the window. Not only the calculation form that substitutes into the radiation temperature calculation formula as the temperature, but also the corrected indoor temperature obtained by performing various corrections on the measurement room temperature is substituted into the radiation temperature calculation formula as the indoor surface temperature for the wall, A calculation form may be adopted in which the corrected outside air temperature subjected to the correction is substituted into the radiation temperature calculation formula as the indoor surface temperature for the window.

例えば、計測室内温度と実際の壁部室内表面温度との温度差を検証し、この温度差分だけ計測室内温度を補正した差分補正室内温度を壁用の室内表面温度として放射温度演算式に代入したり、計測外気温度と実際の窓部室内表面温度との温度差を検証し、この温度差分だけ計測外気温度を補正した差分補正外気温度を窓用の室内表面温度として放射温度演算式に代入する演算形態を採るなどしてもよい。 For example, the temperature difference between the measured room temperature and the actual wall interior surface temperature is verified, and the difference-corrected room temperature obtained by correcting the measured room temperature by this temperature difference is substituted into the radiation temperature equation as the wall interior surface temperature. Or verifying the temperature difference between the measured outside air temperature and the actual indoor surface temperature of the window, and substituting the corrected outside air temperature by correcting the measured outside air temperature by this temperature difference into the radiation temperature calculation formula as the indoor surface temperature for the window. An arithmetic form may be adopted.

本発明の第２特徴構成は、第１特徴構成の実施に好適な実施形態を採るものであり、その特徴は、
前記制御手段は、前記放射温度演算ステップにおいて、空調対象室の計測室内温度を室内表面の材質に応じて補正した材質補正室内温度を演算し、
この演算で求めた演算材質補正室内温度を前記室内表面温度として前記放射温度演算式に代入する演算形態で空調対象室の平均放射温度を演算する構成にしてある点にある。 The second characteristic configuration of the present invention, which take the preferred embodiment in the practice of the first feature structure, its features,
In the radiation temperature calculation step, the control means calculates a material correction room temperature obtained by correcting the measurement room temperature of the air-conditioning target room according to the material of the room surface,
The average radiation temperature of the air-conditioning target room is calculated in a calculation form in which the calculated material correction room temperature obtained by this calculation is substituted into the radiation temperature calculation formula as the room surface temperature.

つまり、室内温度に対する室内表面温度の依存度は、その室内表面の材質によって異なり、例えば、金属製の室内表面における表面温度は、木製や樹脂製などの室内表面における表面温度に比べて室内放射温度に対する依存度の方が高い場合もある。 In other words, the dependence of the indoor surface temperature on the indoor temperature varies depending on the material of the indoor surface. For example, the surface temperature of a metal indoor surface is higher than the surface temperature of the indoor surface of wood or resin. In some cases, the dependence on is higher.

特に、放射冷房や放射暖房を行う場合、天井面などの放射面からの放射冷熱や放射温熱が照射される箇所の室内表面からは、その箇所における室内表面の材質によっては、二次的な冷熱放射や温熱放射が生じることもあり、このことから、空調対象室の平均放射温度を演算する上で室内表面の材質は重要な影響因子である。 In particular, when performing radiant cooling or radiant heating, from the indoor surface of a location irradiated with radiant cold or radiant heat from a radiant surface such as a ceiling surface, depending on the material of the indoor surface at that location, secondary cooling Radiation and thermal radiation may occur, and for this reason, the material of the indoor surface is an important influencing factor in calculating the average radiation temperature of the air-conditioning target room.

したがって、放射温度演算ステップにおいて、計測室内温度を室内表面の材質に応じて補正した材質補正室内温度を室内表面温度として放射温度演算式に代入する演算形態で空調対象室の平均放射温度を演算する上記構成によれば、空調対象室の平均放射温度として、実際の平均放射温度により近い一層正確な平均放射温度を演算することができ、これにより、室内温度演算ステップで演算する室内温度も一層正確なものにすることができて、実際に得られる体感温度と設定体感温度との誤差がより小さい一層優れた体感温度基準の室内空調を実現することができる。 Therefore, in the radiation temperature calculation step, the average radiation temperature of the air-conditioning target room is calculated in a calculation form in which the material-corrected room temperature obtained by correcting the measured room temperature according to the material of the indoor surface is substituted into the radiation temperature calculation formula as the room surface temperature. According to the above configuration, it is possible to calculate a more accurate average radiation temperature that is closer to the actual average radiation temperature as the average radiation temperature of the air-conditioning target room, thereby further accurately calculating the indoor temperature calculated in the indoor temperature calculation step. Therefore, it is possible to realize a more excellent room temperature-based air conditioning with a smaller error between the actually obtained temperature and the set temperature.

なお、この構成の実施においては、計測室内温度を室内表面の材質に応じて補正する材質補正のみを計測室内温度に施すのに限らず、材質補正と他の補正とを計測室内温度に施した複式補正室内温度を演算し、この演算複式補正室内温度を室内表面温度として放射温度演算式に代入する演算形態で空調対象室の平均放射温度を演算するようにしてもよい。 In the implementation of this configuration, not only the material correction for correcting the measurement room temperature according to the material of the indoor surface is performed on the measurement room temperature, but also the material correction and other corrections are performed on the measurement room temperature. The average radiant temperature of the air-conditioning target room may be calculated in a calculation form in which the compound correction indoor temperature is calculated and the calculated compound correction room temperature is substituted into the radiation temperature calculation expression as the room surface temperature.

例えば、空調対象室の計測室内温度を室内表面の材質に応じて補正する材質補正と、計測室内温度と実際の室内表面温度との温度差分だけ計測室内温度を補正する前述の差分補正とを夫々、重み付けした状態で計測室内温度に施した複式補正室内温度を演算し、この演算複式補正室内温度を室内表面温度として放射温度演算式に代入する演算形態で空調対象室の平均放射温度を演算するようにしてもよい。 For example, the material correction for correcting the measured indoor temperature of the air-conditioning target room according to the material of the indoor surface and the above-described difference correction for correcting the measured indoor temperature by the temperature difference between the measured indoor temperature and the actual indoor surface temperature, respectively. Calculating the double-corrected room temperature applied to the measured room temperature in a weighted state, and calculating the average radiant temperature of the air-conditioning target room in a calculation form that substitutes the calculated double-corrected room temperature as the room surface temperature in the radiation temperature calculation formula You may do it.

図１は天井放射空調設備の設備構成を示し、同図１に示すように、空調対象室１（１ａ，１ｂ）の天井裏空間２には、ヒートポンプ式の空調機３（具体的にはその室内器）を設置してある。 FIG. 1 shows the equipment configuration of a ceiling radiant air conditioner. As shown in FIG. 1, a heat pump type air conditioner 3 (specifically, a heat pump type air conditioner 3 is installed in the ceiling back space 2 of the air conditioning target room 1 (1a, 1b). An indoor unit) is installed.

この空調機３には、室外器側に装備した室外熱交換器、圧縮機、膨張弁とともに冷凍回路を構成する室内熱交換器３ａを装備するとともに、室内ファン３ｂを装備してある。 The air conditioner 3 is equipped with an indoor heat exchanger 3a that constitutes a refrigeration circuit together with an outdoor heat exchanger, a compressor, and an expansion valve provided on the outdoor unit side, and an indoor fan 3b.

なお、４ａ，４ｂは空調機３（室内器）とその室外器とを接続する高圧側及び低圧側の２本の冷媒配管である。 Reference numerals 4a and 4b are two refrigerant pipes on the high-pressure side and the low-pressure side that connect the air conditioner 3 (indoor unit) and the outdoor unit.

空調機３の空気導入口３ｉと空調対象室１の天井板５に装備した還気口６とは、天井裏空間２に施設した還気ダクト７により接続してあり、また、空調機３の空気送出口３ｏには天井裏空間２に施設した給気ダクト８を接続してある。 The air introduction port 3i of the air conditioner 3 and the return air port 6 provided in the ceiling plate 5 of the air conditioning target room 1 are connected by a return air duct 7 installed in the ceiling space 2. An air supply duct 8 provided in the ceiling space 2 is connected to the air outlet 3o.

そして、空調対象室１の天井裏空間２において、給気ダクト８の先端部には、空調機３の空気送出口３ｏから給気ダクト８を通じて送られる温度調整空気ＳＡを天井裏空間２に拡散させる多孔金属板製の錐状の拡散器９を装備してある。 In the ceiling back space 2 of the air conditioning target room 1, the temperature adjustment air SA sent from the air outlet 3 o of the air conditioner 3 through the air supply duct 8 is diffused into the ceiling back space 2 at the tip of the air supply duct 8. It is equipped with a conical diffuser 9 made of a perforated metal plate.

空調対象室１の天井板５は多孔金属板により形成してあり、拡散器９から天井裏空間２に拡散された温度調整空気ＳＡは、天井裏空間２に充満した状態で多孔金属板製の天井板５と熱交換した後、天井板５における多数の孔５ａを通じて空調対象室１に供給される。 The ceiling plate 5 of the air conditioning target room 1 is formed of a porous metal plate, and the temperature-adjusted air SA diffused from the diffuser 9 to the ceiling back space 2 is made of a porous metal plate in a state where the ceiling back space 2 is filled. After exchanging heat with the ceiling plate 5, the air is supplied to the air-conditioned room 1 through a number of holes 5 a in the ceiling plate 5.

つまり、冷房運転では、室内ファン３ｂにより還気口６から還気ダクト７を通じて空調機３に導入した空調対象室１の室内空気ＲＡを、冷凍回路における蒸発器として機能する状態にある室内熱交換器３ａにより冷却し、この冷却空気を温度調整空気ＳＡとして室内ファン３ｂにより給気ダクト８を通じて拡散器９から天井裏空間２に拡散させる。 That is, in the cooling operation, the indoor air RA in the air-conditioning target room 1 introduced into the air conditioner 3 from the return air port 6 through the return air duct 7 by the indoor fan 3b is in a state of functioning as an evaporator in the refrigeration circuit. Cooling is performed by the apparatus 3a, and this cooling air is diffused from the diffuser 9 to the ceiling back space 2 through the air supply duct 8 by the indoor fan 3b as the temperature adjustment air SA.

そして、この冷却空気ＳＡを天井裏空間２に充満させた状態で多孔金属板製の天井板５と熱交換させて天井板５を冷却することで、多孔金属板製の天井板５から空調対象室１に対して放射冷房を施し、また、最終的に天井板５における多数の孔５ａを通じて空調対象室１に供給する熱交換後の冷却空気ＳＡにより、空調対象室１に対して補助的な対流冷房を施す。 Then, the ceiling plate 5 is cooled by exchanging heat with the ceiling plate 5 made of a porous metal plate in a state in which the ceiling air space 2 is filled with the cooling air SA, so that the ceiling plate 5 made of the porous metal plate is cooled. The room 1 is radiatively cooled, and is finally supplemented to the air-conditioning target room 1 by the cooling air SA after heat exchange supplied to the air-conditioning target room 1 through the numerous holes 5a in the ceiling plate 5. Apply convection cooling.

The heated air is diffused from the diffuser 9 to the ceiling space 2 through the air supply duct 8 by the indoor fan 3b as the temperature adjusted air SA.

そして、この加熱空気ＳＡを天井裏空間２に充満させた状態で多孔金属板製の天井板５と熱交換させて天井板５を加熱することで、多孔金属板製の天井板５から空調対象室１に対して放射暖房を施し、また、最終的に天井板５における多数の孔５ａを通じて空調対象室１に供給する熱交換後の加熱空気ＳＡにより、空調対象室１に対して補助的な対流暖房を施す。 Then, the ceiling plate 5 is heated by exchanging heat with the ceiling plate 5 made of a porous metal plate in a state where the ceiling air space 2 is filled with the heated air SA, so that the ceiling plate 5 made of the porous metal plate is subject to air conditioning. The room 1 is radiantly heated, and is finally supplemented to the air-conditioning target room 1 by the heated air SA after heat exchange supplied to the air-conditioning target room 1 through the numerous holes 5a in the ceiling plate 5.

図２に示すように、空調対象施設Ｋにおける２室の空調対象室１（１ａ，１ｂ）夫々の天井裏空間２には、上記の如き還気口６及び拡散器９を備える空調機３を二台ずつ配備するとともに外気調整機１０を配備してある。 As shown in FIG. 2, an air conditioner 3 provided with the return air port 6 and the diffuser 9 as described above is installed in the ceiling space 2 of each of the two air-conditioning target rooms 1 (1a, 1b) in the air-conditioning target facility K. Two units are deployed, and the outside air adjuster 10 is deployed.

この外気調整機１０の外気導入口１０ａと屋外に臨ませた外気取入口１１とは、天井裏空間２に施設した外気導入ダクト１２により接続し、外気調整機１０の調整外気送出口１０ｂと空調対象室１の天井板５に装備した給気口１３とは、同じく天井裏空間２に施設した調整外気供給ダクト１４により接続してある。 The outside air inlet 10a of the outside air adjuster 10 and the outside air inlet 11 exposed outdoors are connected by an outside air introduction duct 12 provided in the ceiling space 2, and the adjusted outside air outlet 10b of the outside air adjuster 10 and the air conditioning are connected. The air supply port 13 provided in the ceiling plate 5 of the target room 1 is connected by the adjusted outside air supply duct 14 provided in the ceiling back space 2.

また、外気調整機１０の排気導入口１０ｃと空調対象室１の天井板５に装備した排気口１５とは、天井裏空間２に施設した排気ダクト１６により接続し、外気調整機１０の排気送出口１０ｄと屋外に臨ませた排気放出口１７とは、同じく天井裏空間２に施設した排気送出ダクト１８により接続してある。 Further, the exhaust air inlet 10c of the outside air adjuster 10 and the exhaust port 15 provided in the ceiling plate 5 of the air-conditioning target room 1 are connected by the exhaust duct 16 provided in the ceiling back space 2, and the exhaust air supply of the outside air adjuster 10 is performed.

By transferring to the outside air OA introduced into the outside air adjuster 10 through the introduction duct 12, the introduction outside air OA is heated and humidified.

そして、このように加熱及び加湿した調整外気ＯＡを内装ファンにより調整外気供給ダクト１４及び給気口１３を通じて空調対象室１に供給することで、空調対象室１の暖房状態を安定的に保ちながら、空調対象室１を調整外気ＯＡにより換気し、一方、保有熱及び保有水分を導入外気ＯＡに受け渡した排出空気ＥＡは、内装ファンにより排気送出ダクト１８を通じて排気放出口１７から屋外に放出する。 Then, the heated and humidified adjusted outside air OA is supplied to the air-conditioning target room 1 through the adjusted outside air supply duct 14 and the air supply port 13 by the internal fan, so that the heating state of the air-conditioned target room 1 is stably maintained. The air-conditioning target room 1 is ventilated with the adjusted outside air OA, and the exhaust air EA that has transferred the retained heat and the retained moisture to the introduced outside air OA is discharged from the exhaust discharge port 17 to the outside through the exhaust delivery duct 18 by the internal fan.

By doing so, the sensible temperature teq obtained in each air-conditioning target room 1a, 1b is automatically adjusted to the set sensible temperature (specifically, the set values teq1 to teq3 for each seasonal mode).
