Description

空気調和装置Air conditioner
　この発明は空気調和装置に関し、特に、設定された目標時刻に室温が目標温度になるように、目標時刻よりも早い時刻から冷房または暖房を行なう空気調和装置に関する。 The present invention relates to an air conditioner, and more particularly to an air conditioner that performs cooling or heating from a time earlier than the target time so that the room temperature becomes the target temperature at the set target time.
　従来より、設定された目標時刻に室温が目標温度になるように、目標時刻よりも予備運転時間だけ早い時刻に室内機を起動させる空気調和装置がある（たとえば、特許文献１参照）。このような空気調和装置では、室内機の起動時における室温と目標温度との温度差ΔＴと、室内機の運転時間ｔＤとの関係に基づいてゲイン（ｔＤ／ΔＴ）を学習し、室温を目標温度にするために必要な予備運転時間ｔＤを求める。 Conventionally, there is an air conditioner that starts an indoor unit at a time earlier than the target time by a preliminary operation time so that the room temperature becomes the target temperature at the set target time (see, for example, Patent Document 1). In such an air conditioner, the gain (tD / ΔT) is learned based on the relationship between the temperature difference ΔT between the room temperature and the target temperature when the indoor unit is started, and the operation time tD of the indoor unit, and the room temperature is targeted. A preliminary operation time tD necessary for obtaining the temperature is obtained.
特開２０１４－２０７２０号公報JP 2014-20720 A
　しかし、温度差ΔＴと運転時間ｔＤとの関係は一般的には線形でないので、１つのゲインのみを用いて学習すると、予備運転時間ｔＤの精度が低下するという問題がある（図４、図９参照）。予備運転時間ｔＤが長過ぎると、目標時刻ｔｓよりも早い時刻に目標温度Ｔｓに到達してしまい、電力が無駄に消費される。逆に、予備運転時間ｔＤが短か過ぎると、目標時刻ｔｓになっても室温Ｔｒが目標温度Ｔｓにならず、快適性が低下してしまう。 However, since the relationship between the temperature difference ΔT and the operation time tD is generally not linear, there is a problem that if the learning is performed using only one gain, the accuracy of the preliminary operation time tD decreases (FIGS. 4 and 9). reference). If the preliminary operation time tD is too long, the target temperature Ts is reached at a time earlier than the target time ts, and power is wasted. On the other hand, if the preliminary operation time tD is too short, the room temperature Tr does not become the target temperature Ts even when the target time ts is reached, and comfort is reduced.
　それゆえに、この発明の主たる目的は、室内機の予備運転時間を高精度で求めることが可能な空気調和装置を提供することである。 Therefore, a main object of the present invention is to provide an air conditioner capable of obtaining the preliminary operation time of the indoor unit with high accuracy.
　この発明に係る空気調和装置は、室温を調整する室内機と、室温を検出する温度検出器と、目標温度を設定するための温度設定部と、目標時刻を設定するための時刻設定部と、目標時刻に室温が目標温度に到達するように、目標時刻よりも予備運転時間だけ早い時刻に室内機を起動させる制御装置とを備えたものである。制御装置は、室内機の過去の運転データに基づいて、室内機の起動時における室温と目標温度との温度差と、室内機の運転時間との関係を学習する学習部と、学習部の学習結果に基づいて、室温を目標温度にするために必要な予備運転時間を求める演算部とを含む。学習部は、温度差と室内機の運転時間との関係を温度差の大きさに応じて第１～第Ｎの学習領域に分割し、各学習領域毎に温度差と室内機の運転時間との関係を学習する。Ｎは２以上の整数である。 An air conditioner according to the present invention includes an indoor unit that adjusts a room temperature, a temperature detector that detects the room temperature, a temperature setting unit that sets a target temperature, a time setting unit that sets a target time, And a controller that activates the indoor unit at a time earlier than the target time by a preliminary operation time so that the room temperature reaches the target temperature at the target time. The control device has a learning unit that learns a relationship between a temperature difference between a room temperature and a target temperature at the time of starting the indoor unit and an operation time of the indoor unit based on past operation data of the indoor unit, and learning of the learning unit And a calculation unit that obtains a preliminary operation time necessary for setting the room temperature to the target temperature based on the result. The learning unit divides the relationship between the temperature difference and the operation time of the indoor unit into first to Nth learning regions according to the magnitude of the temperature difference, and for each learning region, the temperature difference and the operation time of the indoor unit To learn the relationship. N is an integer of 2 or more.
　この発明に係る空気調和装置では、室内機の起動時における室温と目標温度との温度差と、室内機の運転時間との関係を温度差の大きさに応じて複数の学習領域に分割し、各学習領域毎に温度差と室内機の運転時間との関係を学習し、その学習結果に基づいて予備運転時間を求める。したがって、温度差が小さな学習領域においても、温度差が大きな学習領域においても、温度差と室内機の運転時間との関係を高精度で学習することができ、その結果、室内機の予備運転時間を高精度で求めることができる。 In the air conditioner according to the present invention, the relationship between the temperature difference between the room temperature and the target temperature at the start of the indoor unit and the operation time of the indoor unit is divided into a plurality of learning regions according to the magnitude of the temperature difference, The relationship between the temperature difference and the operation time of the indoor unit is learned for each learning region, and the preliminary operation time is obtained based on the learning result. Therefore, it is possible to learn the relationship between the temperature difference and the operation time of the indoor unit with high accuracy both in the learning region where the temperature difference is small and in the learning region where the temperature difference is large. Can be obtained with high accuracy.

　[実施の形態１]
　図１は、この発明の実施の形態１による空気調和装置の構成を示すブロック図である。図１において、この空気調和装置は、室内機１、操作部３、および制御装置６を備える。室内機１は、図２に示すように、室内９の壁の上部、あるいは天井に取り付けられ、冷房時には冷風を吹き出し、暖房時には温風を吹き出し、室内温度を調整するものである。 [Embodiment 1]
1 is a block diagram showing a configuration of an air-conditioning apparatus according to Embodiment 1 of the present invention. In FIG. 1, the air conditioner includes an indoor unit 1, an operation unit 3, and a control device 6. As shown in FIG. 2, the indoor unit 1 is attached to the upper part of the wall or the ceiling of the room 9, and blows out cool air during cooling and blows out warm air during heating to adjust the room temperature.
　図１に戻って、室内機１は、制御装置６によって制御される。室内機１は、冷房時には、室内空気を吸い込み、吸い込んだ室内空気を冷やして吹き出し、室内温度Ｔｒを目標温度Ｔｓに下げる。室内機１は、暖房時には、室内空気を吸い込み、吸い込んだ室内空気を暖めて吹き出し、室内温度Ｔｒを目標温度Ｔｓに上げる。室内機１には、温度検出器２が設けられている。温度検出器２は、室温（室内空気の温度）Ｔｒを検出し、検出値を示す信号を制御装置６に出力する。 Referring back to FIG. 1, the indoor unit 1 is controlled by the control device 6. During cooling, the indoor unit 1 sucks room air, cools and sucks out the sucked room air, and lowers the room temperature Tr to the target temperature Ts. During heating, the indoor unit 1 sucks indoor air, warms and sucks out the sucked indoor air, and raises the indoor temperature Tr to the target temperature Ts. The indoor unit 1 is provided with a temperature detector 2. The temperature detector 2 detects a room temperature (room air temperature) Tr and outputs a signal indicating the detected value to the control device 6.
　操作部３は、目標温度設定部４および目標時刻設定部５を含む。目標温度設定部４は、目標温度Ｔｓを設定するために、空気調和装置のユーザによって操作される。目標時刻設定部５は、目標時刻ｔｓを設定するために、空気調和装置のユーザによって操作される。目標時刻ｔｓは、ユーザにとって室内温度Ｔｒが目標温度Ｔｓになっていて欲しい時刻である。たとえば、ユーザが帰宅する時刻を目標時刻ｔｓとして設定すると、その目標時刻ｔｓよりも予備運転時間ｔＤだけ早い時刻に室内機１が起動され、ユーザが帰宅した時刻（すなわち目標時刻ｔｓ）に室内９が目標温度Ｔｓに調整される。 The operation unit 3 includes a target temperature setting unit 4 and a target time setting unit 5. The target temperature setting unit 4 is operated by the user of the air conditioner in order to set the target temperature Ts. The target time setting unit 5 is operated by the user of the air conditioner in order to set the target time ts. The target time ts is a time at which the user wants the room temperature Tr to become the target temperature Ts. For example, when the time when the user returns home is set as the target time ts, the indoor unit 1 is activated at a time earlier than the target time ts by the preliminary operation time tD, and the indoor 9 Is adjusted to the target temperature Ts.
　操作部３は、たとえば、ユーザによって操作されるリモートコントロール装置であり、電源のオン／オフ、冷房と暖房の切り換え、目標温度Ｔｓの設定、目標時刻ｔｓの設定などを行なうための複数のボタン、設定された目標温度Ｔｓ、目標時刻ｔｓなどを表示する液晶表示装置、時刻を示す時計、設定された目標温度Ｔｓ、目標時刻ｔｓなどを示す信号を制御装置６に送信する送信機などを含む。 The operation unit 3 is, for example, a remote control device operated by a user, and includes a plurality of buttons for performing power on / off, switching between cooling and heating, setting a target temperature Ts, setting a target time ts, A liquid crystal display device that displays the set target temperature Ts, the target time ts, and the like, a clock that indicates the time, a transmitter that transmits a signal indicating the set target temperature Ts, the target time ts, and the like to the control device 6 are included.
　制御装置６は、室内機１の筐体内に設けられていてもよいし、筐体外に設けられていても構わない。制御装置６は、操作部３および温度検出器２からの信号に従って室内機１を制御する。制御装置６は、目標時刻ｔｓに室温Ｔｒが目標温度Ｔｓに到達するように、目標時刻ｔｓよりも予備運転時間ｔＤだけ前の起動時刻ｔｘに室内機１を起動させる。制御装置６は、学習部７および演算部８を含む。 The control device 6 may be provided in the housing of the indoor unit 1 or may be provided outside the housing. The control device 6 controls the indoor unit 1 in accordance with signals from the operation unit 3 and the temperature detector 2. The control device 6 activates the indoor unit 1 at the activation time tx that is the preliminary operation time tD before the target time ts so that the room temperature Tr reaches the target temperature Ts at the target time ts. The control device 6 includes a learning unit 7 and a calculation unit 8.
　学習部７は、室内機１が運転される度に、操作部３の時計(図示せず)からの時刻を示す信号、室内機１の温度検出器２からの信号などに基づいて、運転時間ｔＤと室温Ｔｒの関係（室内機１の運転データ）を取得し、内蔵メモリ(図示せず)に記録する。学習部７は、記録した過去の運転データに基づいて、室内機１の起動時における室温Ｔｒと目標温度Ｔｓとの温度差ΔＴと、室内機１の運転時間ｔＤとの関係を学習する。学習部７は、温度差ΔＴと室内機１の運転時間ｔＤとの関係を第１～第Ｎの学習領域に分割し、各学習領域毎に温度差ΔＴと室内機１の運転時間ｔＤとの関係を学習する。Ｎは２以上の整数である。ここでは、Ｎ＝２の場合について説明する。第１の学習領域における温度差ΔＴは、第２の学習領域における温度差ΔＴよりも小さい。 Each time the indoor unit 1 is operated, the learning unit 7 operates based on a signal indicating a time from a clock (not shown) of the operation unit 3, a signal from the temperature detector 2 of the indoor unit 1, and the like. The relationship between tD and room temperature Tr (operation data of indoor unit 1) is acquired and recorded in a built-in memory (not shown). The learning unit 7 learns the relationship between the temperature difference ΔT between the room temperature Tr and the target temperature Ts when the indoor unit 1 is started, and the operation time tD of the indoor unit 1 based on the recorded past operation data. The learning unit 7 divides the relationship between the temperature difference ΔT and the operation time tD of the indoor unit 1 into first to Nth learning regions, and the temperature difference ΔT and the operation time tD of the indoor unit 1 for each learning region. Learn relationships. N is an integer of 2 or more. Here, a case where N = 2 is described. The temperature difference ΔT in the first learning region is smaller than the temperature difference ΔT in the second learning region.
　学習部７は、各学習領域毎に温度差ΔＴと運転時間ｔＤとの関係を直線で近似する。学習部７は、冷房時における温度差ΔＴｃ＝Ｔｒ－Ｔｓと運転時間ｔＤｃとの関係を学習するとともに、暖房時における温度差ΔＴｈ＝Ｔｓ－Ｔｒと運転時間ｔＤｈとの関係を学習する。 The learning unit 7 approximates the relationship between the temperature difference ΔT and the operation time tD with a straight line for each learning region. The learning unit 7 learns the relationship between the temperature difference ΔTc = Tr−Ts during cooling and the operation time tDc, and learns the relationship between the temperature difference ΔTh = Ts−Tr during heating and the operation time tDh.
　演算部８は、学習部７の学習結果に基づいて、室温Ｔｒを温度差ΔＴ分だけ変更するために必要な室内機１の予備運転時間ｔＤを求める。演算部８は、冷房時には、室温Ｔｒを温度差ΔＴｃ分だけ低下させるために必要な室内機１の予備運転時間（予冷時間）ｔＤｃを求める。演算部８は、暖房時には、室温Ｔｒを温度差ΔＴｈ分だけ上昇させるために必要な室内機１の予備運転時間（予暖時間）ｔＤｈを求める。 The calculation unit 8 obtains the preliminary operation time tD of the indoor unit 1 necessary for changing the room temperature Tr by the temperature difference ΔT based on the learning result of the learning unit 7. The arithmetic unit 8 obtains a preliminary operation time (precooling time) tDc of the indoor unit 1 necessary for lowering the room temperature Tr by the temperature difference ΔTc during cooling. The arithmetic unit 8 obtains a preliminary operation time (pre-warming time) tDh of the indoor unit 1 necessary for raising the room temperature Tr by the temperature difference ΔTh during heating.
　制御装置６は、目標時刻設定部５を用いて設定された目標時刻ｔｓと現在時刻ｔｎとの差Δｔ＝ｔｓ－ｔｎと、演算部８によって求められた予備運転時間ｔＤとを比較し、ｔＤ≦Δｔとなったことに応じて室内機１を起動させる。 The control device 6 compares the difference Δt = ts−tn between the target time ts set by using the target time setting unit 5 and the current time tn with the preliminary operation time tD obtained by the calculation unit 8, and tD The indoor unit 1 is activated in response to ≦ Δt.
　次に、冷房時における空気調和装置の動作についてより詳細に説明する。図３は、冷房時における室内機１の運転時間ｔＤｃと室温Ｔｒとの関係を示す図である。図３において、室内機１を起動させると、室温Ｔｒは徐々に低下する。冷房開始時には室温Ｔｒは速く低下するが、時間が経過して室温Ｔｒが低くなると、室温Ｔｒの低下速度が遅くなる。これは、時間が経過して外気温度と室温Ｔｒの差が大きくなるに従って、室外から室内９に進入する熱が増大するからである。学習部７は、操作部３の時計(図示せず)からの時刻を示す信号、室内機１の温度検出器２からの信号などに基づいて、図３に示した運転時間ｔＤと室温Ｔｒの関係（室内機１の運転データ）を取得し、内蔵メモリ(図示せず)に記録する。 Next, the operation of the air conditioner during cooling will be described in more detail. FIG. 3 is a diagram illustrating the relationship between the operation time tDc of the indoor unit 1 and the room temperature Tr during cooling. In FIG. 3, when the indoor unit 1 is started, the room temperature Tr gradually decreases. At the start of cooling, the room temperature Tr decreases rapidly, but when the room temperature Tr decreases with time, the rate of decrease of the room temperature Tr decreases. This is because the heat entering the room 9 from the outside increases as the difference between the outside temperature and the room temperature Tr increases with time. The learning unit 7 determines the operation time tD and the room temperature Tr shown in FIG. 3 based on a signal indicating a time from a clock (not shown) of the operation unit 3 and a signal from the temperature detector 2 of the indoor unit 1. The relationship (operation data of the indoor unit 1) is acquired and recorded in a built-in memory (not shown).
　図４は、冷房時における温度差ΔＴｃと室内機１の運転時間ｔＤｃとの関係を示す図である。温度差ΔＴｃは、室内機１の起動時の室温Ｔｒと目標温度Ｔｓとの差ΔＴｃ＝Ｔｒ－Ｔｓである。すなわち冷房時における温度差ΔＴｃは、室温Ｔｒから目標温度Ｔｓを減算した値である。図４に示すように、温度差ΔＴｃが小さい場合は曲線Ｃ１の接線の傾きｔＤｃ／ΔＴｃは小さく、温度差ΔＴｃが大きくなる程に曲線Ｃ１の接線の傾きｔＤｃ／ΔＴｃが大きくなる。学習部７は、室内機１の過去の運転データに基づいて、温度差ΔＴｃと室内機１の運転時間ｔＤｃとの関係を示す曲線Ｃ１を得る。 FIG. 4 is a diagram showing the relationship between the temperature difference ΔTc during cooling and the operation time tDc of the indoor unit 1. The temperature difference ΔTc is a difference ΔTc = Tr−Ts between the room temperature Tr and the target temperature Ts when the indoor unit 1 is started. That is, the temperature difference ΔTc during cooling is a value obtained by subtracting the target temperature Ts from the room temperature Tr. As shown in FIG. 4, when the temperature difference ΔTc is small, the tangent slope tDc / ΔTc of the curve C1 is small, and as the temperature difference ΔTc increases, the tangential slope tDc / ΔTc of the curve C1 increases. The learning unit 7 obtains a curve C1 indicating the relationship between the temperature difference ΔTc and the operation time tDc of the indoor unit 1 based on past operation data of the indoor unit 1.
　このように、温度差ΔＴｃと室内機１の運転時間ｔＤｃとの関係は、一般的には直線ではなく曲線Ｃ１で表される。この特性を１本の直線（たとえばＬ０）を用いて近似しようとすると、ｔＤｃ／ΔＴｃの誤差が大きくなる。そこで、本実施の形態１では、学習部７は、図５に示すように、温度差ΔＴｃと運転時間ｔＤｃの関係を温度差ΔＴｃの大きさに応じて第１の学習領域Ａ１と第２の学習領域Ａ２とに分割し、第１および第２の学習領域Ａ１，Ａ２の各々において温度差ΔＴｃと室内機１の運転時間ｔＤｃとの関係を学習する。第１の学習領域Ａ１はΔＴｃ＜Ｔ１の領域であり、第２の学習領域Ａ２はＴ１＜ΔＴｃの領域である。 Thus, the relationship between the temperature difference ΔTc and the operation time tDc of the indoor unit 1 is generally represented by a curve C1 instead of a straight line. If this characteristic is approximated using one straight line (for example, L0), the error of tDc / ΔTc increases. Therefore, in the first embodiment, the learning unit 7 changes the relationship between the temperature difference ΔTc and the operation time tDc according to the magnitude of the temperature difference ΔTc, as shown in FIG. The learning area A2 is divided, and the relationship between the temperature difference ΔTc and the operation time tDc of the indoor unit 1 is learned in each of the first and second learning areas A1 and A2. The first learning area A1 is an area where ΔTc <T1, and the second learning area A2 is an area where T1 <ΔTc.
　学習部７は、第１の学習領域Ａ１における温度差ΔＴｃと運転時間ｔＤｃとの関係を直線Ｌ１で近似し、第２の学習領域Ａ２における温度差ΔＴｃと運転時間ｔＤｃとの関係を直線Ｌ２で近似する。その際、最小二乗法を用いて近似してもよいし、他の方法を用いて近似してもよい。第１および第２の学習領域Ａ１，Ａ２の境界値ΔＴｃ＝Ｔ１は、予め決めておいてもよいし、温度差ΔＴｃと運転時間ｔＤｃとの関係を直線Ｌ１，Ｌ２で近似しながら決定してもかまわない。たとえば、直線Ｌ１は数式ｔＤｃ＝Ａ×ΔＴｃで表されて学習部７に記憶され、直線Ｌ２は数式ｔＤｃ＝Ｂ×ΔＴｃ－Ｃで表されて学習部７に記憶される。Ａ，Ｂ，Ｃの各々は正の実数であり、Ａ＜Ｂである。 The learning unit 7 approximates the relationship between the temperature difference ΔTc and the operation time tDc in the first learning region A1 with a straight line L1, and the relationship between the temperature difference ΔTc and the operation time tDc in the second learning region A2 with a straight line L2. Approximate. In that case, you may approximate using the least squares method, and you may approximate using another method. The boundary value ΔTc = T1 between the first and second learning regions A1 and A2 may be determined in advance, or determined by approximating the relationship between the temperature difference ΔTc and the operation time tDc with the straight lines L1 and L2. It doesn't matter. For example, the straight line L1 is expressed by the mathematical expression tDc = A × ΔTc and stored in the learning unit 7, and the straight line L2 is expressed by the mathematical expression tDc = B × ΔTc−C and stored in the learning unit 7. Each of A, B, and C is a positive real number, and A <B.
　演算部８は、温度検出器２によって検出された室温Ｔｒと、目標温度設定部４を用いて設定された目標温度Ｔｓとに基づいて温度差ΔＴｃ＝Ｔｒ－Ｔｓを求める。演算部８は、学習部７によって学習された温度差ΔＴｃと運転時間ｔＤｃとの関係に基づき、室温Ｔｒを温度差ΔＴｃだけ低下させるために必要な予備運転時間ｔＤｃを求める。 The calculation unit 8 obtains a temperature difference ΔTc = Tr−Ts based on the room temperature Tr detected by the temperature detector 2 and the target temperature Ts set using the target temperature setting unit 4. Based on the relationship between the temperature difference ΔTc learned by the learning unit 7 and the operation time tDc, the calculation unit 8 obtains the preliminary operation time tDc necessary for reducing the room temperature Tr by the temperature difference ΔTc.

　図６は、冷房時における制御装置６の動作を示すフローチャートである。学習部７によって温度差ΔＴｃと運転時間ｔＤｃとの関係が直線Ｌ１，Ｌ２によって近似され、目標温度設定部４を用いて目標温度Ｔｓが設定され、目標時刻設定部５を用いて目標時刻ｔｓが設定されたものとする。 [Control during cooling]
FIG. 6 is a flowchart showing the operation of the control device 6 during cooling. The learning unit 7 approximates the relationship between the temperature difference ΔTc and the operation time tDc by straight lines L1 and L2, sets the target temperature Ts using the target temperature setting unit 4, and sets the target time ts using the target time setting unit 5. It shall be set.
　ステップＳ１において制御装置６の演算部８は、温度検出器２によって検出された室温Ｔｒと目標温度設定部４を用いて設定された目標温度Ｔｓとの温度差ΔＴｃ＝Ｔｒ－Ｔｓを求める。ステップＳ２において演算部８は、学習部７によって学習された温度差ΔＴｃと運転時間ｔＤｃとの関係（図５の直線Ｌ１，Ｌ２）に基づいて、ステップＳ１で求めた温度差ΔＴｃ分だけ室温Ｔｒを低下させるのに必要な予備運転時間ｔＤｃを求める。 In step S1, the calculation unit 8 of the control device 6 obtains a temperature difference ΔTc = Tr−Ts between the room temperature Tr detected by the temperature detector 2 and the target temperature Ts set using the target temperature setting unit 4. In step S2, the calculation unit 8 calculates the room temperature Tr by the temperature difference ΔTc obtained in step S1 based on the relationship between the temperature difference ΔTc learned by the learning unit 7 and the operation time tDc (straight lines L1, L2 in FIG. 5). The preliminary operation time tDc required to reduce the value is obtained.
　ステップＳ３において制御装置６は、目標時刻設定部５を用いて設定された目標時刻ｔｓと現在時刻ｔｎとの差Δｔ＝ｔｓ－ｔｎを求める。ステップＳ４において制御装置６は、ｔＤｃ≦Δｔであるか否かを判別し、ｔＤｃ≦Δｔでない場合はステップＳ３に戻り、ｔＤｃ≦Δｔである場合はステップＳ５において室内機１を起動させる。したがって、室内機１は、目標時刻ｔｓよりも予備運転時間ｔＤｃだけ早い時刻ｔｘ＝ｔｓ－ｔＤｃに起動される。 In step S3, the control device 6 obtains a difference Δt = ts−tn between the target time ts set using the target time setting unit 5 and the current time tn. In step S4, the control device 6 determines whether or not tDc ≦ Δt. If tDc ≦ Δt is not satisfied, the process returns to step S3, and if tDc ≦ Δt, the indoor unit 1 is activated in step S5. Therefore, the indoor unit 1 is activated at time tx = ts−tDc, which is earlier than the target time ts by the preliminary operation time tDc.
　図７は、冷房時における室温Ｔｒの時間変化を例示する図である。図７に示すように、目標時刻ｔｓよりも予備運転時間ｔＤｃだけ早い時刻ｔｘに室内機１の運転が開始され、室温Ｔｒが低下し、目標時刻ｔｓにおいて室温Ｔｒが目標温度Ｔｓに到達する。 FIG. 7 is a diagram illustrating the time change of the room temperature Tr during cooling. As shown in FIG. 7, the operation of the indoor unit 1 is started at time tx that is earlier than the target time ts by the preliminary operation time tDc, the room temperature Tr is lowered, and the room temperature Tr reaches the target temperature Ts at the target time ts.

　次に、暖房時における空気調和装置の動作について詳細に説明する。図８は、暖房時における室内機１の運転時間ｔＤｃと室温Ｔｒとの関係を示す図である。図８において、室内機１を起動させると、室温Ｔｒは徐々に上昇する。暖房開始時には室温Ｔｒは速く上昇するが、時間が経過して室温Ｔｒが高くなると、室温Ｔｒの上昇速度が遅くなる。これは、時間が経過して外気温度と室温Ｔｒの差が大きくなるに従って、室外から室内９に進入する熱が増大するからである。学習部７は、室内機１が暖房運転される度に、操作部３の時計(図示せず)からの時刻を示す信号、室内機１の温度検出器２からの信号などに基づいて、図８に示した運転時間ｔＤと室温Ｔｒの関係（室内機１の運転データ）を取得し、内蔵メモリ(図示せず)に記録する。 [Control during heating]
Next, the operation of the air conditioner during heating will be described in detail. FIG. 8 is a diagram illustrating a relationship between the operation time tDc of the indoor unit 1 during heating and the room temperature Tr. In FIG. 8, when the indoor unit 1 is activated, the room temperature Tr gradually increases. At the start of heating, the room temperature Tr rises rapidly, but when the room temperature Tr increases with time, the room temperature Tr rises slowly. This is because the heat entering the room 9 from the outside increases as the difference between the outside temperature and the room temperature Tr increases with time. Each time the indoor unit 1 is operated for heating, the learning unit 7 displays a signal based on a signal indicating a time from a clock (not shown) of the operation unit 3 and a signal from the temperature detector 2 of the indoor unit 1. 8 is acquired (operation data of the indoor unit 1) and recorded in a built-in memory (not shown).
　図９は、暖房時における温度差ΔＴｈと室内機１の運転時間ｔＤｈとの関係を示す図である。温度差ΔＴｈは、目標温度Ｔｓと室内機１の起動時の室温Ｔｒとの差ΔＴｈ＝Ｔｓ－Ｔｒである。すなわち暖房時における温度差ΔＴｈは、目標温度Ｔｓから室温Ｔｒを減算した値である。図９に示すように、温度差ΔＴｈが小さい場合は曲線Ｃ１１の接線の傾きｔＤｈ／ΔＴｈは小さく、温度差ΔＴｈが大きくなる程に曲線Ｃ１１の接線の傾きｔＤｈ／ΔＴｈが大きくなる。学習部７は、内蔵メモリ(図示せず)に記録した過去の運転データに基づいて、温度差ΔＴｈと室内機１の運転時間ｔＤｈとの関係を示す曲線Ｃ１１を得る。 FIG. 9 is a diagram showing the relationship between the temperature difference ΔTh during heating and the operation time tDh of the indoor unit 1. The temperature difference ΔTh is a difference ΔTh = Ts−Tr between the target temperature Ts and the room temperature Tr when the indoor unit 1 is started. That is, the temperature difference ΔTh during heating is a value obtained by subtracting the room temperature Tr from the target temperature Ts. As shown in FIG. 9, when the temperature difference ΔTh is small, the tangent slope tDh / ΔTh of the curve C11 is small, and as the temperature difference ΔTh increases, the tangential slope tDh / ΔTh of the curve C11 increases. The learning unit 7 obtains a curve C11 indicating the relationship between the temperature difference ΔTh and the operation time tDh of the indoor unit 1 based on past operation data recorded in a built-in memory (not shown).
　このように、温度差ΔＴｈと室内機１の運転時間ｔＤｈとの関係は、一般的には直線ではなく曲線Ｃ１１で表される。この特性を１本の直線（たとえばＬ１０）を用いて近似しようとすると、ｔＤｈ／ΔＴｈの誤差が大きくなる。そこで、本実施の形態１では、学習部７は、図１０に示すように、温度差ΔＴｈと室内機１の運転時間ｔＤｈとの関係を温度差ΔＴｈの大きさに応じて第１の学習領域Ａ１１と第２の学習領域Ａ１２とに分割し、第１および第２の学習領域Ａ１１，Ａ１２の各々において温度差ΔＴｈと室内機１の運転時間ｔＤｈとの関係を学習する。第１の学習領域Ａ１１はΔＴｈ＜Ｔ１１の領域であり、第２の学習領域Ａ１２はＴ１１＜ΔＴｈの領域である。 Thus, the relationship between the temperature difference ΔTh and the operation time tDh of the indoor unit 1 is generally represented not by a straight line but by a curve C11. If this characteristic is approximated using a single straight line (for example, L10), the error of tDh / ΔTh increases. Therefore, in the first embodiment, as shown in FIG. 10, the learning unit 7 determines the relationship between the temperature difference ΔTh and the operation time tDh of the indoor unit 1 in the first learning region according to the magnitude of the temperature difference ΔTh. Dividing into A11 and the second learning area A12, the relationship between the temperature difference ΔTh and the operating time tDh of the indoor unit 1 is learned in each of the first and second learning areas A11, A12. The first learning region A11 is a region where ΔTh <T11, and the second learning region A12 is a region where T11 <ΔTh.
　学習部７は、第１の学習領域Ａ１１における温度差ΔＴｈと運転時間ｔＤｈとの関係を直線Ｌ１１で近似し、第２の学習領域Ａ１２における温度差ΔＴｈと運転時間ｔＤｈとの関係を直線Ｌ１２で近似する。その際、最小二乗法を用いて近似してもよいし、他の方法を用いて近似してもよい。第１および第２の学習領域Ａ１１，Ａ１２の境界値ΔＴｃ＝Ｔ１１は、予め決めておいてもよいし、温度差ΔＴｈと運転時間ｔＤｈとの関係を直線Ｌ１，Ｌ２で近似しながら決定してもかまわない。たとえば、直線Ｌ１１は数式ｔＤｃ＝Ｅ×ΔＴｃで表されて学習部７に記憶され、直線Ｌ１２は数式ｔＤｃ＝Ｆ×ΔＴｃ－Ｇで表されて学習部７に記憶される。Ｅ，Ｆ，Ｇの各々は正の実数であり、Ｅ＜Ｆである。 The learning unit 7 approximates the relationship between the temperature difference ΔTh and the operation time tDh in the first learning region A11 with a straight line L11, and the relationship between the temperature difference ΔTh and the operation time tDh in the second learning region A12 with a straight line L12. Approximate. In that case, you may approximate using the least squares method, and you may approximate using another method. The boundary value ΔTc = T11 between the first and second learning areas A11, A12 may be determined in advance, or determined by approximating the relationship between the temperature difference ΔTh and the operation time tDh with the straight lines L1, L2. It doesn't matter. For example, the straight line L11 is expressed by the mathematical expression tDc = E × ΔTc and stored in the learning unit 7, and the straight line L12 is expressed by the mathematical expression tDc = F × ΔTc−G and stored in the learning unit 7. Each of E, F, and G is a positive real number, and E <F.
　演算部８は、温度検出器２によって検出された室温Ｔｒと、目標温度設定部４を用いて設定された目標温度Ｔｓとに基づいて温度差ΔＴｈ＝Ｔｓ－Ｔｒを求める。演算部８は、学習部７によって学習された温度差ΔＴｈと運転時間ｔＤｈとの関係（図５の直線Ｌ１１，Ｌ１２）に基づき、室温Ｔｒを温度差ΔＴｈだけ上昇させるために必要な予備運転時間ｔＤｈを求める。 The calculation unit 8 obtains a temperature difference ΔTh = Ts−Tr based on the room temperature Tr detected by the temperature detector 2 and the target temperature Ts set using the target temperature setting unit 4. The calculation unit 8 is based on the relationship between the temperature difference ΔTh learned by the learning unit 7 and the operation time tDh (straight lines L11 and L12 in FIG. 5), and the preliminary operation time necessary for increasing the room temperature Tr by the temperature difference ΔTh. tDh is obtained.
　図１１は、暖房時における制御装置６の動作を示すフローチャートである。学習部７によって温度差ΔＴｈと運転時間ｔＤｈとの関係が学習され、目標温度設定部４を用いて目標温度Ｔｓが設定され、目標時刻設定部５を用いて目標時刻ｔｓが設定されたものとする。 FIG. 11 is a flowchart showing the operation of the control device 6 during heating. The learning unit 7 learns the relationship between the temperature difference ΔTh and the operation time tDh, the target temperature Ts is set using the target temperature setting unit 4, and the target time ts is set using the target time setting unit 5. To do.
　ステップＳ１１において制御装置６の演算部８は、目標温度設定部４を用いて設定された目標温度Ｔｓと温度検出器２によって検出された室温Ｔｒとの温度差ΔＴｈ＝Ｔｓ－Ｔｒを求める。ステップＳ１２において演算部８は、学習部７によって学習された温度差ΔＴｈと運転時間ｔＤｈとの関係（図１０の直線Ｌ１１，Ｌ１２）に基づいて、ステップＳ１１で求めた温度差ΔＴｈ分だけ室温Ｔｒを上昇させるのに必要な予備運転時間ｔＤｈを求める。 In step S11, the calculation unit 8 of the control device 6 obtains a temperature difference ΔTh = Ts−Tr between the target temperature Ts set using the target temperature setting unit 4 and the room temperature Tr detected by the temperature detector 2. In step S12, the arithmetic unit 8 calculates the room temperature Tr by the temperature difference ΔTh obtained in step S11 based on the relationship between the temperature difference ΔTh learned by the learning unit 7 and the operation time tDh (straight lines L11, L12 in FIG. 10). The preliminary operation time tDh required to raise the value is obtained.
　ステップＳ１３において制御装置６は、目標時刻設定部５を用いて設定された目標時刻ｔｓと現在時刻ｔｎとの差Δｔを求める。ステップＳ１４において制御装置６は、ｔＤｈ≦Δｔであるか否かを判別し、ｔＤｈ≦Δｔでない場合はステップＳ１３に戻り、ｔＤｈ≦Δｔである場合はステップＳ１５において室内機１を起動させる。したがって、室内機１は、目標時刻ｔｓよりも予備運転時間ｔＤｈだけ早い時刻ｔｘ＝ｔｓ－ｔＤｈに起動される。 In step S13, the control device 6 obtains a difference Δt between the target time ts set using the target time setting unit 5 and the current time tn. In step S14, the control device 6 determines whether or not tDh ≦ Δt. If tDh ≦ Δt is not satisfied, the process returns to step S13, and if tDh ≦ Δt, the indoor unit 1 is activated in step S15. Therefore, the indoor unit 1 is activated at time tx = ts−tDh that is earlier than the target time ts by the preliminary operation time tDh.
　図１２は、暖房時における室温Ｔｒの時間変化を例示する図である。図１２示すように、目標時刻ｔｓよりも予備運転時間ｔＤｈだけ早い時刻ｔｘに室内機１の運転が開始され、室温Ｔｒが上昇し、目標時刻ｔｓにおいて室温Ｔｒが目標温度Ｔｓに到達する。 FIG. 12 is a diagram illustrating the time change of the room temperature Tr during heating. As shown in FIG. 12, the operation of the indoor unit 1 is started at time tx that is earlier than the target time ts by the preliminary operation time tDh, the room temperature Tr rises, and the room temperature Tr reaches the target temperature Ts at the target time ts.
　以上のように、この実施の形態１では、室内機１の起動時における室温Ｔｒと目標温度Ｔｓとの温度差ΔＴｃ（またはΔＴｈ）と、室内機１の運転時間ｔＤｃ（またはｔＤｈ）との関係を温度差ΔＴｃ（またはΔＴｈ）の大きさに応じて複数の学習領域Ａ１，Ａ２（またはＡ１１，Ａ１２）に分割し、各学習領域毎に温度差ΔＴｃ（またはΔＴｈ）と室内機１の運転時間ｔＤｃ（またはｔＤｈ）との関係を学習し、その学習結果に基づいて室内機１の予備運転時間ｔＤｃ（またはｔＤｈ）を求める。 As described above, in the first embodiment, the relationship between the temperature difference ΔTc (or ΔTh) between the room temperature Tr and the target temperature Ts when the indoor unit 1 is started and the operation time tDc (or tDh) of the indoor unit 1. Is divided into a plurality of learning areas A1, A2 (or A11, A12) according to the magnitude of the temperature difference ΔTc (or ΔTh), and the temperature difference ΔTc (or ΔTh) and the operation time of the indoor unit 1 are determined for each learning area. The relationship with tDc (or tDh) is learned, and the preliminary operation time tDc (or tDh) of the indoor unit 1 is obtained based on the learning result.
　したがって、温度差ΔＴｃ（またはΔＴｈ）が小さな学習領域においても、温度差ΔＴｃ（またはΔＴｈ）が大きな学習領域においても、温度差ΔＴｃ（またはΔＴｈ）と室内機１の運転時間ｔＤｃ（またはｔＤｈ）との関係を高精度で求めることができ、その結果、室内機１の予備運転時間ｔＤｃ（またはｔＤｈ）を高精度で求めることができる。このため、目標時刻ｔｓよりも早い時刻に室温Ｔｒが目標温度Ｔｓに到達して消費電力が増大したり、目標時刻ｔｓよりも遅い時刻に室温Ｔｒが目標温度Ｔｓに到達して快適性が低下することを防止することができ、省エネ性と快適性を両立した最適な起動制御を実現することができる。 Therefore, the temperature difference ΔTc (or ΔTh) and the operation time tDc (or tDh) of the indoor unit 1 are also obtained in the learning region where the temperature difference ΔTc (or ΔTh) is small and in the learning region where the temperature difference ΔTc (or ΔTh) is large. Can be obtained with high accuracy, and as a result, the preliminary operation time tDc (or tDh) of the indoor unit 1 can be obtained with high accuracy. For this reason, the room temperature Tr reaches the target temperature Ts at a time earlier than the target time ts and power consumption increases, or the room temperature Tr reaches the target temperature Ts at a time later than the target time ts, resulting in a decrease in comfort. This makes it possible to realize optimal start-up control that achieves both energy saving and comfort.
　[実施の形態２]
　実施の形態１では、図５（または図１０）で示したように、温度差ΔＴｃ（またはΔＴｈ）と運転時間ｔＤｃ（またはｔＤｈ）の関係を２つの直線Ｌ１，Ｌ２（またはＬ１１，Ｌ１２）によって近似し、室内機１の予備運転時間ｔＤｃ（またはｔＤｈ）を求め、目標時刻ｔｓよりも予備運転時間ｔＤｃ（またはｔＤｈ）だけ早い時刻ｔｘに室内機１を起動させた。しかし、温度差ΔＴｃ（またはΔＴｈ）が小さい場合は、室温Ｔｒから目標温度Ｔｓに変化させる時間が短くなり、室温Ｔｒがオーバーシュートする場合がある。 [Embodiment 2]
In the first embodiment, as shown in FIG. 5 (or FIG. 10), the relationship between the temperature difference ΔTc (or ΔTh) and the operation time tDc (or tDh) is represented by two straight lines L1, L2 (or L11, L12). The preliminary operation time tDc (or tDh) of the indoor unit 1 is obtained by approximation, and the indoor unit 1 is started at a time tx that is earlier than the target time ts by the preliminary operation time tDc (or tDh). However, when the temperature difference ΔTc (or ΔTh) is small, the time for changing from the room temperature Tr to the target temperature Ts is shortened, and the room temperature Tr may overshoot.
　図１３は、冷房時における室温Ｔｒの時間変化を例示する図であって、図７と対比される図である。図１３に示すように、室温Ｔｒと目標温度Ｔｓとの温度差ΔＴｃ＝Ｔｒ－Ｔｓが小さい場合は、室内機１の予備運転時間ｔＤｃが短くなり、室温Ｔｒが目標温度Ｔｓよりも低下してしまう場合がある。このように、室温Ｔｒがオーバーシュートしてしまうと、オーバーシュートした分だけ電力が無駄に消費される。 FIG. 13 is a diagram illustrating the time change of the room temperature Tr during cooling, and is a diagram contrasted with FIG. As shown in FIG. 13, when the temperature difference ΔTc = Tr−Ts between the room temperature Tr and the target temperature Ts is small, the preliminary operation time tDc of the indoor unit 1 becomes short, and the room temperature Tr decreases below the target temperature Ts. May end up. As described above, when the room temperature Tr overshoots, power is wasted as much as the overshoot.
　この問題は、暖房時でも同様である。目標温度Ｔｓと室温Ｔｒとの温度差ΔＴｈ＝Ｔｓ－Ｔｒが小さい場合は、室内機１の予備運転時間ｔＤｈが短くなり、室温Ｔｒが目標温度Ｔｓを超えてしまう場合がある。この場合も、オーバーシュート分だけ電力が無駄に消費される。本実施の形態２では、この問題の解決が図られる。 This problem is the same even when heating. When the temperature difference ΔTh = Ts−Tr between the target temperature Ts and the room temperature Tr is small, the preliminary operation time tDh of the indoor unit 1 is shortened, and the room temperature Tr may exceed the target temperature Ts. In this case, too much power is wasted for the overshoot. In the second embodiment, this problem can be solved.

The heat exchanger 12 performs heat exchange between cold water (or hot water) supplied from the heat source device 10 and room air. The room air is cooled by cold water during cooling, and the room air is warmed by hot water during heating. The cooling capacity increases according to the flow rate of cold water, and the heating capacity increases according to the flow rate of hot water.
　送風機１３は、制御装置６Ａによって制御され、室内空気を吸い込んで熱交換器１２に供給する。冷房時は、熱交換器１２において冷やされた空気が室内９に吹き出される。暖房時は、熱交換器１２において温められた空気が室内９に吹き出される。送風機１３によって生成される風量は制御可能になっている。冷房能力および暖房能力はともに、送風機１３の風量に応じて増大する。 The blower 13 is controlled by the control device 6 </ b> A, sucks room air, and supplies it to the heat exchanger 12.

The amount of air generated by the blower 13 can be controlled. Both the cooling capacity and the heating capacity increase according to the air volume of the blower 13.
　温度検出器２は、室温Ｔｒを検出し、検出値を示す信号を制御装置６Ａに出力する。温度検出器１４は、配管１７を通過する冷水（または温水）の温度を検出し、検出値を示す信号を制御装置６Ａに出力する。 The temperature detector 2 detects the room temperature Tr and outputs a signal indicating the detected value to the control device 6A. The temperature detector 14 detects the temperature of cold water (or hot water) passing through the pipe 17 and outputs a signal indicating the detected value to the control device 6A.
　操作部３は、図１で示したものであり、目標温度Ｔｓおよび目標時刻ｔｓの設定などを行なうためにユーザによって使用される。制御装置６Ａは、図１で示した学習、演算機能に加え、操作部３からの信号、温度検出器２，１４の出力信号に基づいて、熱源機１０、流量調整弁１１、および送風機１３を制御する。制御装置６Ａは、室内機１Ａの筐体内に設けられていてもよいし、室内機１Ａの筐体外に設けられていても構わない。 The operation unit 3 is the one shown in FIG. 1, and is used by the user to set the target temperature Ts and the target time ts. In addition to the learning and calculation functions shown in FIG. 1, the control device 6 </ b> A controls the heat source device 10, the flow rate adjustment valve 11, and the blower 13 based on signals from the operation unit 3 and output signals from the temperature detectors 2 and 14.

　次に、この空気調和装置の動作について説明する。冷房時には、室内熱交換器２５で室内空気と熱交換された冷媒が四方弁２２を介して圧縮機２１の吸込口２１ａに供給され、圧縮機２１によって圧縮される。圧縮機２１の吐出口２１ｂから吐出された高温で高圧の冷媒は、四方弁２２を介して室外熱交換器２３に供給され、室外熱交換器２３で外気と熱交換される。室外熱交換器２３で熱交換された冷媒は、膨張弁２４によって膨張されて低温になる。膨張した低温の冷媒は、室内熱交換器２５で室内空気と熱交換した後、四方弁２２を介して圧縮機２１の吸込口２１ａに戻る。室内空気は、送風機２６によって吸い込まれ、室内熱交換器２５で冷やされた後に、室内９に吹き出される。 Next, the operation of this air conditioner will be described. At the time of cooling, the refrigerant heat-exchanged with indoor air by the indoor heat exchanger 25 is supplied to the suction port 21a of the compressor 21 through the four-way valve 22 and is compressed by the compressor 21. The high-temperature and high-pressure refrigerant discharged from the discharge port 21 b of the compressor 21 is supplied to the outdoor heat exchanger 23 via the four-way valve 22, and heat is exchanged with the outside air in the outdoor heat exchanger 23. The refrigerant heat-exchanged by the outdoor heat exchanger 23 is expanded by the expansion valve 24 and becomes a low temperature. The expanded low-temperature refrigerant exchanges heat with indoor air in the indoor heat exchanger 25, and then returns to the suction port 21a of the compressor 21 via the four-way valve 22. The room air is sucked by the blower 26 and cooled by the indoor heat exchanger 25 and then blown out into the room 9.
　目標時刻ｔｓが設定された場合、制御装置６Ｂは、図１５で示したように、室温Ｔｒと目標温度Ｔｓの温度差ΔＴｃがＴ１よりも小さな第１の学習領域Ａ１にあり、直線Ｌ１に基づいて冷房を開始する場合は、送風機２６の送風能力を低レベルに設定する。これにより、室内機１Ｂの冷房能力を小さくして室温Ｔｒのオーバーシュートを抑制し、消費電力を低減化することができる。 When the target time ts is set, as shown in FIG. 15, the control device 6B is in the first learning region A1 where the temperature difference ΔTc between the room temperature Tr and the target temperature Ts is smaller than T1, and is based on the straight line L1. When the cooling is started, the blowing capacity of the blower 26 is set to a low level. Thereby, the cooling capability of the indoor unit 1B can be reduced, the overshoot of the room temperature Tr can be suppressed, and the power consumption can be reduced.
　制御装置６Ｂは、室温Ｔｒと目標温度Ｔｓの温度差ΔＴｃがＴ１よりも大きな第２の学習領域Ａ２にあり、直線Ｌ２に基づいて冷房を開始する場合は、送風機２６の送風能力を高レベルに設定する。これにより、室内機１Ｂの冷房能力を大きくして室温Ｔｒを迅速に目標温度Ｔｓにすることが可能となる。 When the temperature difference ΔTc between the room temperature Tr and the target temperature Ts is in the second learning region A2 where the control device 6B is larger than T1, and the cooling is started based on the straight line L2, the air blowing capacity of the blower 26 is set to a high level. Set. As a result, the cooling capacity of the indoor unit 1B can be increased, and the room temperature Tr can be quickly set to the target temperature Ts.
　暖房時には、室外熱交換器２３で外気と熱交換された冷媒が四方弁２２を介して圧縮機２１の吸込口２１ａに供給され、圧縮機２１によって圧縮される。圧縮機２１の吐出口２１ｂから吐出された高温で高圧の冷媒は、四方弁２２を介して室内熱交換器２５に供給され、室内熱交換器２５で室内空気と熱交換される。室内空気は、送風機２６によって吸い込まれ、室内熱交換器２５で温められた後に、室内９に吹き出される。室内熱交換器２５で熱交換された冷媒は、膨張弁２４によって膨張されて低温になる。膨張した低温の冷媒は、室内熱交換器２５で室内空気と熱交換した後、四方弁２２を介して圧縮機２１の吸込口２１ａに戻る。 During heating, the refrigerant heat-exchanged with the outside air by the outdoor heat exchanger 23 is supplied to the suction port 21 a of the compressor 21 through the four-way valve 22 and is compressed by the compressor 21. The high-temperature and high-pressure refrigerant discharged from the discharge port 21 b of the compressor 21 is supplied to the indoor heat exchanger 25 through the four-way valve 22, and is heat-exchanged with indoor air in the indoor heat exchanger 25. The room air is sucked by the blower 26 and heated by the indoor heat exchanger 25 and then blown into the room 9. The refrigerant heat-exchanged by the indoor heat exchanger 25 is expanded by the expansion valve 24 and becomes a low temperature. The expanded low-temperature refrigerant exchanges heat with indoor air in the indoor heat exchanger 25, and then returns to the suction port 21a of the compressor 21 via the four-way valve 22.
　制御装置６Ｂは、図１６で示したように、目標温度Ｔｓと室温Ｔｒの温度差ΔＴｈがＴ１１よりも小さな第１の学習領域Ａ１１にあり、直線Ｌ１１に基づいて暖房を開始する場合は、送風機２６の送風能力を低レベルに設定する。これにより、室内機１Ｂの暖房能力を小さくして室温Ｔｒのオーバーシュートを抑制し、消費電力を低減化することができる。 As shown in FIG. 16, the control device 6B is in the first learning region A11 where the temperature difference ΔTh between the target temperature Ts and the room temperature Tr is smaller than T11, and when the heating starts based on the straight line L11, 26 blowing capacity is set to a low level. Thereby, the heating capability of the indoor unit 1B can be reduced, the overshoot of the room temperature Tr can be suppressed, and the power consumption can be reduced.
　制御装置６Ｂは、目標温度Ｔｓと室温Ｔｒの温度差ΔＴｈがＴ１１よりも大きな第２の学習領域Ａ１２にあり、直線Ｌ１２に基づいて暖房を開始する場合は、送風機２６の送風能力を高レベルに設定する。これにより、室内機１Ｂの暖房能力を大きくして室温Ｔｒを迅速に目標温度Ｔｓにすることが可能となる。 The control device 6B is in the second learning area A12 where the temperature difference ΔTh between the target temperature Ts and the room temperature Tr is larger than T11, and when the heating is started based on the straight line L12, the blowing capacity of the blower 26 is set to a high level. Set. Thereby, the heating capability of the indoor unit 1B can be increased, and the room temperature Tr can be quickly set to the target temperature Ts.
　なお、この実施の形態３では、温度差ΔＴｃ（またはΔＴｈ）が第１の学習領域Ａ１（またはＡ１１）である場合における送風機２６の送風能力を、温度差ΔＴｃ（またはΔＴｈ）が第２の学習領域Ａ２（またはＡ１２）である場合における送風機２６の送風能力よりも低くしたが、これに限るものではなく、温度差ΔＴｃ（またはΔＴｈ）が第１の学習領域Ａ１（またはＡ１１）である場合における空調能力を、温度差ΔＴｃ（またはΔＴｈ）が第２の学習領域Ａ２（またはＡ１２）である場合における空調能力よりも低くすれば同じ効果が得られる。 In the third embodiment, the blowing capacity of the blower 26 when the temperature difference ΔTc (or ΔTh) is in the first learning region A1 (or A11), and the temperature difference ΔTc (or ΔTh) is the second learning. Although it was lower than the blowing capacity of the blower 26 in the case of the region A2 (or A12), the present invention is not limited to this, and the temperature difference ΔTc (or ΔTh) is the first learning region A1 (or A11). The same effect can be obtained if the air conditioning capacity is made lower than the air conditioning capacity when the temperature difference ΔTc (or ΔTh) is in the second learning region A2 (or A12).
　空調能力を下げる方法としては、圧縮機２１の運転周波数を下げる方法がある。圧縮機２１の運転周波数を下げると、圧縮機２１から吐出される冷媒の温度および圧力が低下し、冷媒の流量が小さくなる。膨張弁２４の開度は、圧縮機２１の運転周波数に応じて設定される。圧縮機２１および膨張弁２４は、共同して、冷媒（熱媒体）の流量を調整する流量調整部と、冷媒（熱媒体）の温度を調整する温度調整部との両方を構成する。 As a method of reducing the air conditioning capacity, there is a method of reducing the operating frequency of the compressor 21. When the operating frequency of the compressor 21 is lowered, the temperature and pressure of the refrigerant discharged from the compressor 21 are lowered, and the flow rate of the refrigerant is reduced. The opening degree of the expansion valve 24 is set according to the operating frequency of the compressor 21. The compressor 21 and the expansion valve 24 jointly constitute both a flow rate adjusting unit that adjusts the flow rate of the refrigerant (heat medium) and a temperature adjusting unit that adjusts the temperature of the refrigerant (heat medium).
