　上記換気用熱交換器４２の水入口は、上記第３の熱動弁２６３に接続され、換気用熱交換器４２の水出口は、上記戻りヘッダ２５に接続されている。つまり、上記第１、上記第２の床暖房パネル３１，３２と上記換気用熱交換器４２とは、上記水熱交換器２１に並列に接続されている。 The water inlet of the ventilation heat exchanger 42 is connected to the third thermal valve 263, and the water outlet of the ventilation heat exchanger 42 is connected to the return header 25. That is, the first and second floor heating panels 31 and 32 and the ventilation heat exchanger 42 are connected in parallel to the water heat exchanger 21.
　上記圧縮機１と、上記四路弁２と、上記室外熱交換器３と、上記膨張弁５と、上記水熱交換器２１とは、環状に接続されて、熱媒回路（ヒートポンプ）を構成している。圧縮機１の運転により、この熱媒回路内を、熱媒が循環する。熱媒としては、例えば、冷媒である。室外熱交換器３は、室外ファン４からの空気と熱媒との間で、熱交換を行う。 The compressor 1, the four-way valve 2, the outdoor heat exchanger 3, the expansion valve 5, and the water heat exchanger 21 are connected in a ring to form a heat medium circuit (heat pump). is doing. The heat medium circulates in the heat medium circuit by the operation of the compressor 1. An example of the heat medium is a refrigerant. The outdoor heat exchanger 3 performs heat exchange between the air from the outdoor fan 4 and the heat medium.
　上水熱交換器２１と、上記ポンプ２３と、上記第１、上記第２の床暖房パネル３１，３２および上記換気用熱交換器４２とは、環状に接続されて、水回路を構成している。ポンプ２３の運転により、この水回路内を、水が循環する。つまり、ポンプ２３は、第１、第２の床暖房パネル３１，３２および換気用熱交換器４２に、水を供給する。 The water heat exchanger 21, the pump 23, the first and second floor heating panels 31 and 32, and the ventilation heat exchanger 42 are annularly connected to form a water circuit. Yes. Water is circulated in the water circuit by the operation of the pump 23. That is, the pump 23 supplies water to the first and second floor heating panels 31 and 32 and the ventilation heat exchanger 42.
　上記水熱交換器２１は、熱媒と水との間で、熱交換を行う。例えば、水熱交換器２１は、水を熱媒で加熱して、温水を生成する。上記換気用熱交換器４２は、水と吸入外気との間で、熱交換を行う。例えば、換気用熱交換器４２は、吸入外気を温水で加熱し、上記換気装置４１の凍結を防止する。 The water heat exchanger 21 performs heat exchange between the heat medium and water. For example, the water heat exchanger 21 heats water with a heat medium to generate hot water. The ventilation heat exchanger 42 exchanges heat between water and the intake outside air. For example, the ventilation heat exchanger 42 heats the intake outside air with warm water to prevent the ventilation device 41 from freezing.
　上記制御装置５０は、凍結防止制御部５１と第１の水温変更部５２とを有する。第１の水温変更部５２は、第１の液温変更部の一例である。 The control device 50 includes a freeze prevention control unit 51 and a first water temperature changing unit 52. The first water temperature changing unit 52 is an example of a first liquid temperature changing unit.
　上記凍結防止制御部５１は、上記換気ファン４１２が運転され、かつ、上記換気用熱交換器４２に供給される前の吸入外気の温度が、予め定められた設定値以下のときに、換気用熱交換器４２に温水を供給するように制御する。上記設定値は、換気装置４１の凍結を防止できる温度とし、例えば、－１５℃である。 The freeze prevention control unit 51 is used for ventilation when the ventilation fan 412 is operated and the temperature of the intake outside air before being supplied to the ventilation heat exchanger 42 is equal to or lower than a predetermined set value. Control is performed to supply hot water to the heat exchanger 42. The set value is a temperature at which the ventilation device 41 can be prevented from freezing, and is, for example, −15 ° C.
　上記第１の水温変更部５２は、上記換気用熱交換器４２に供給される前の吸入外気の温度に応じて、換気用熱交換器４２に供給される水の温度を変更する。具体的に述べると、第１の水温変更部５２は、吸入外気の温度が低くなるにつれて、水温を高くする。 The first water temperature changing unit 52 changes the temperature of the water supplied to the ventilation heat exchanger 42 according to the temperature of the intake outside air before being supplied to the ventilation heat exchanger 42. Specifically, the first water temperature changing unit 52 increases the water temperature as the temperature of the intake outside air decreases.
　次に、上記温調システムの動作について説明する。 Next, the operation of the temperature control system will be described.
　上記第１の床暖房パネル３１で床暖房運転を行う場合、ユーザが図示しない運転スイッチをオンすることで、制御装置５０の制御により、第１の熱動弁２６１を開き、ポンプ２３を運転して、水回路の水を循環する。圧縮機１から吐出した高温高圧の熱媒は、実線の矢印に示すように流れて、水熱交換器２１で二次側を流れる水と熱交換される。これにより、温水ユニット２００の水は、加熱され、室外ユニット１００の熱媒は、凝縮する。水熱交換器２１の一次側からの熱媒は、膨張弁５で減圧された後、室外熱交換器３で外気との熱交換により蒸発し、圧縮機１の吸入側に戻る。同様に、上記第２の床暖房パネル３２で床暖房運転を行う場合、ユーザが図示しない運転スイッチをオンする。 When the floor heating operation is performed with the first floor heating panel 31, the user turns on an operation switch (not shown) to open the first thermal valve 261 and operate the pump 23 under the control of the control device 50. Circulate the water in the water circuit. The high-temperature and high-pressure heat medium discharged from the compressor 1 flows as indicated by solid arrows, and is heat-exchanged with water flowing on the secondary side by the water heat exchanger 21. Thereby, the water of the hot water unit 200 is heated, and the heat medium of the outdoor unit 100 is condensed. The heat medium from the primary side of the water heat exchanger 21 is depressurized by the expansion valve 5, evaporates by heat exchange with the outside air in the outdoor heat exchanger 3, and returns to the suction side of the compressor 1. Similarly, when the floor heating operation is performed by the second floor heating panel 32, the user turns on an operation switch (not shown).
　一方、上記換気用熱交換器４２の凍結防止運転は、上記凍結防止制御部５１の制御により、行われる。つまり、図２に示すように、換気ファン４１２が運転され（ステップＳ１）、上記第１の温度センサ６２によって測定された換気用熱交換器４２の上流の吸入外気の温度が、上記設定値（－１５℃）以下であると（ステップＳ２）、凍結防止制御部５１は、換気用熱交換器４２に温水を供給するように制御する（ステップＳ３）。具体的に述べると、凍結防止制御部５１は、第３の熱動弁２６３を開けて、換気用熱交換器４２に温水を供給する。 On the other hand, the freeze prevention operation of the ventilation heat exchanger 42 is performed under the control of the freeze prevention control unit 51. That is, as shown in FIG. 2, the ventilation fan 412 is operated (step S1), and the temperature of the intake outside air upstream of the ventilation heat exchanger 42 measured by the first temperature sensor 62 is the set value ( If it is not higher than −15 ° C. (step S2), the freeze prevention control unit 51 controls to supply hot water to the ventilation heat exchanger 42 (step S3). Specifically, the freeze prevention control unit 51 opens the third thermal valve 263 and supplies hot water to the ventilation heat exchanger 42.
　これにより、－１５℃の吸入外気は、上記換気用熱交換器４２によって温められて、０℃となり、その後、上記換気本体部４１１で、この０℃の吸入外気と１８℃の排出室内空気とが熱交換を行う。そして、室内には、１３℃の外気が吸入され、室外には、５℃の室内空気が排出される。このように、換気本体部４１１から排出される室内空気は、５℃であるため、換気装置４１で吸入外気と排出室内空気との熱交換の際に生じる凍結を防止することができる。 As a result, the intake outdoor air at −15 ° C. is heated to 0 ° C. by the ventilation heat exchanger 42, and then the intake air at 0 ° C. and the exhaust indoor air at 18 ° C. Performs heat exchange. Then, outside air at 13 ° C. is sucked into the room, and room air at 5 ° C. is discharged outside the room. Thus, since the room air discharged from the ventilation main body 411 is 5 ° C., freezing that occurs when the ventilation device 41 exchanges heat between the intake outside air and the discharge room air can be prevented.
　このとき、上記換気用熱交換器４２に供給される水の温度は、上記換気用熱交換器４２に吸入される吸入外気の温度に応じて、上記第１の水温変更部５２によって、変更される。つまり、第１の水温変更部５２は、吸入外気の温度が低くなると、第３の熱動弁２６３の開度等が大きくなるように制御して、水の温度を高くする。 At this time, the temperature of the water supplied to the ventilation heat exchanger 42 is changed by the first water temperature changing unit 52 according to the temperature of the outside air sucked into the ventilation heat exchanger 42. The That is, the first water temperature changing unit 52 increases the temperature of the water by controlling the opening degree of the third thermal valve 263 to increase when the temperature of the intake outside air decreases.
　なお、上記換気用熱交換器４２に要求される水温が、第１、第２の床暖房パネル３１，３２に要求される水温よりも高い場合、上記第１の水温変更部５２は、上記圧縮機１の図示しないインバータを制御して、熱媒の温度を高くして、換気用熱交換器４２の水温を高くするようにしてもよい。 When the water temperature required for the ventilation heat exchanger 42 is higher than the water temperature required for the first and second floor heating panels 31 and 32, the first water temperature changing unit 52 performs the compression. The inverter (not shown) of the machine 1 may be controlled to increase the temperature of the heat medium so that the water temperature of the ventilation heat exchanger 42 is increased.
　なお、上記室外ユニット１００の上記四路弁２を切り換えて、熱媒が、上記熱媒回路内を、矢印に示す暖房流れとは、反対向きに流れるようにして、上記水熱交換器２１において、上記水回路内の水を、冷却するようにしてもよい。 In the water heat exchanger 21, the four-way valve 2 of the outdoor unit 100 is switched so that the heat medium flows in the heat medium circuit in the direction opposite to the heating flow indicated by the arrow. The water in the water circuit may be cooled.
　上記構成の温調システムによれば、上記第１、上記第２の床暖房パネル３１，３２と上記換気用熱交換器４２とは、上記水熱交換器２１に並列に接続されている。 According to the temperature control system having the above-described configuration, the first and second floor heating panels 31 and 32 and the ventilation heat exchanger 42 are connected in parallel to the water heat exchanger 21.
　これにより、上記第１、上記第２の床暖房パネル３１，３２に温水を供給しながら、上記換気用熱交換器４２へ温水を供給するか否かを選択できて、上記換気装置４１の凍結防止の運転のオンとオフを選択できる。したがって、上記換気用熱交換器４２において、温水の不必要な熱損失を防止できる。 Accordingly, it is possible to select whether or not to supply hot water to the ventilation heat exchanger 42 while supplying hot water to the first and second floor heating panels 31 and 32, and to freeze the ventilation device 41. You can choose on or off prevention driving. Therefore, in the ventilation heat exchanger 42, unnecessary heat loss of hot water can be prevented.
　また、上記第１、上記第２の床暖房パネル３１，３２に温水を供給しなくても、上記換気用熱交換器４２に温水を供給できて、第１、第２の床暖房パネル３１，３２を運転しなくても、上記換気装置４１の凍結を防止できる。したがって、第１、第２の床暖房パネル３１，３２において、温水の不必要な熱損失を防止できる。 Further, even if hot water is not supplied to the first and second floor heating panels 31 and 32, the hot water can be supplied to the ventilation heat exchanger 42, and the first and second floor heating panels 31 and 32 can be supplied. Even if 32 is not operated, the ventilation device 41 can be prevented from freezing. Therefore, unnecessary heat loss of hot water can be prevented in the first and second floor heating panels 31 and 32.
　また、上記水熱交換器２１で熱媒と熱交換された温水を、上記換気用熱交換器４２に直接に供給できて、上記換気装置４１の凍結を防止するために、高い温度の温水を使用できる。したがって、換気装置４１の凍結を確実に防止することができる。 Moreover, the hot water heat-exchanged with the heat medium in the water heat exchanger 21 can be directly supplied to the ventilation heat exchanger 42, and in order to prevent the ventilation device 41 from freezing, hot water having a high temperature is used. Can be used. Therefore, freezing of the ventilation device 41 can be reliably prevented.
　上記構成の温調システムによれば、上記凍結防止制御部５１は、上記換気装置４１の換気ファンが運転され、かつ、上記換気用熱交換器４２に供給される前の吸入外気の温度が、予め定められた設定値以下のときに、上記換気用熱交換器４２に温水を供給するように制御する。これにより、換気装置４１が凍結する可能性がある場合に、換気用熱交換器４２に温水を供給できて、省エネに優れたものとなる。 According to the temperature control system configured as described above, the antifreezing control unit 51 is configured so that the temperature of the intake outside air before the ventilation fan of the ventilation device 41 is operated and supplied to the ventilation heat exchanger 42 is Control is performed so that hot water is supplied to the ventilation heat exchanger 42 when it is equal to or less than a predetermined set value. Thereby, when there exists a possibility that the ventilation apparatus 41 may freeze, warm water can be supplied to the heat exchanger 42 for ventilation, and it becomes the thing excellent in energy saving.
　上記構成の温調システムによれば、上記第１の水温変更部５２は、上記換気用熱交換器４２に供給される前の吸入外気の温度に応じて、上記換気用熱交換器４２に供給される水の温度を変更する。これにより、換気装置４１に供給される吸入外気の温度が、換気装置４１が凍結しない温度になるように、換気用熱交換器４２に供給される水の温度を変更できて、水温を上げすぎず、省エネに優れたものとなる。 According to the temperature control system having the above configuration, the first water temperature changing unit 52 supplies the ventilation heat exchanger 42 according to the temperature of the intake outside air before being supplied to the ventilation heat exchanger 42. Change the temperature of the water to be used. Thereby, the temperature of the water supplied to the ventilation heat exchanger 42 can be changed so that the temperature of the intake outside air supplied to the ventilation device 41 becomes a temperature at which the ventilation device 41 does not freeze, and the water temperature is raised too high. It will be excellent in energy saving.
　（第２の実施形態）
　図１の仮想線は、この発明の第２実施形態の温調システムを示す。この第２の実施形態では、換気ユニット４０に、第２の温度センサ６３が設けられ、制御装置５０に、第２の水温変更部５３が設けられる。第２の水温変更部５３は、第２の液温変更部の一例である。その他の構造は、上記第１の実施形態と同じであるため、その説明を省略する。 (Second Embodiment)
The phantom line of FIG. 1 shows the temperature control system of 2nd Embodiment of this invention. In the second embodiment, the ventilation unit 40 is provided with a second temperature sensor 63, and the control device 50 is provided with a second water temperature changing unit 53. The second water temperature changing unit 53 is an example of a second liquid temperature changing unit. Since other structures are the same as those of the first embodiment, description thereof is omitted.
　図１の仮想線に示すように、上記第２の温度センサ６３は、上記第１の温度センサ６２（上記第１実施形態）の代わりに設けられ、上記換気用熱交換器４２と上記換気装置４１との間の吸入外気の流路に、配置されている。第２の温度センサ６３は、換気用熱交換器４２で水と熱交換された後で、換気装置４１で排出室内空気と熱交換される前の吸入外気の温度を検出する。 As shown by the phantom line in FIG. 1, the second temperature sensor 63 is provided instead of the first temperature sensor 62 (the first embodiment), and the ventilation heat exchanger 42 and the ventilation device. 41 is arranged in the flow path of the intake outside air between 41. The second temperature sensor 63 detects the temperature of the intake outside air after the heat exchange with water by the ventilation heat exchanger 42 and before the heat exchange with the discharge room air by the ventilation device 41.
　上記第２の水温変更部５３は、上記第１の水温変更部５２（上記第１実施形態）の代わりに設けられ、上記第２の温度センサ６３によって検出された吸入外気の温度に応じて、上記換気用熱交換器４２に供給される水の温度を変更する。つまり、第２の水温変更部５３は、第１の水温変更部５２と同様に、吸入外気の温度が低くなると、上記第３の熱動弁２６３や上記圧縮機１のインバータを制御して、換気用熱交換器４２の水温を高くする。 The second water temperature changing unit 53 is provided in place of the first water temperature changing unit 52 (the first embodiment), and according to the temperature of the intake outside air detected by the second temperature sensor 63, The temperature of the water supplied to the ventilation heat exchanger 42 is changed. That is, as with the first water temperature changing unit 52, the second water temperature changing unit 53 controls the third thermal valve 263 and the inverter of the compressor 1 when the temperature of the intake outside air decreases, The water temperature of the ventilation heat exchanger 42 is increased.
　したがって、上記第２の水温変更部５３によって、上記換気装置４１に供給される吸入外気の温度が、換気装置４１が凍結しない温度になるように、換気用熱交換器４２に供給される水の温度を正確に制御できて、水温を上げすぎず、省エネに一層優れたものとなる。 Accordingly, the water supplied to the ventilation heat exchanger 42 is adjusted so that the temperature of the intake outside air supplied to the ventilation device 41 by the second water temperature changing unit 53 becomes a temperature at which the ventilation device 41 does not freeze. The temperature can be accurately controlled, the water temperature is not raised too much, and energy saving is further improved.
　なお、上記第２の温度センサ６３を、上記第１の温度センサ６２とともに設け、上記第２の水温変更部５３を、上記第１の水温変更部５２とともに設けるようにしてもよい。 The second temperature sensor 63 may be provided together with the first temperature sensor 62, and the second water temperature changing unit 53 may be provided together with the first water temperature changing unit 52.
　（第３の実施形態）
　図３Ａと図３Ｂは、この発明の第３実施形態の温調システムを示す。この第３の実施形態は、上記第１の実施形態とは、換気装置の構成が相違する。この相違する構成を以下に説明する。 (Third embodiment)
3A and 3B show a temperature control system according to a third embodiment of the present invention. The third embodiment is different from the first embodiment in the configuration of the ventilation device. This different configuration will be described below.
　図３Ａに示すように、換気装置４１Ａの換気本体部４１１Ａは、通常換気モードＭ１と熱交換換気モードＭ２とを有する。通常換気モードＭ１は、吸入外気と排出室内空気との間で熱交換を行わない。熱交換換気モードＭ２は、吸入外気と排出室内空気との間で熱交換を行う。このモードＭ１，Ｍ２の切換は、例えばダンパーの切換によって、行われる。 As shown in FIG. 3A, the ventilation main body 411A of the ventilation device 41A has a normal ventilation mode M1 and a heat exchange ventilation mode M2. In the normal ventilation mode M1, heat exchange is not performed between the intake outside air and the discharge room air. In the heat exchange ventilation mode M2, heat exchange is performed between the intake outside air and the discharge room air. Switching between the modes M1 and M2 is performed, for example, by switching a damper.
　さらに、この換気装置４１ＡのモードＭ１，Ｍ２に応じて、上記換気用熱交換器４２（図１参照）への水の供給を制御する水供給切換部５４を設けている。水供給切換部５４は、液供給切換部の一例である。水供給切換部５４は、図３Ａに示すように、換気装置４１Ａが通常換気モードＭ１であるとき、換気用熱交換器４２に水を供給しないように制御する。一方、水供給切換部５４は、図３Ｂに示すように、換気装置４１Ａが熱交換換気モードＭ２であるとき、換気用熱交換器４２に水を供給するように制御する。 Furthermore, a water supply switching unit 54 for controlling the supply of water to the ventilation heat exchanger 42 (see FIG. 1) is provided according to the modes M1 and M2 of the ventilation device 41A. The water supply switching unit 54 is an example of a liquid supply switching unit. As shown in FIG. 3A, the water supply switching unit 54 performs control so that water is not supplied to the ventilation heat exchanger 42 when the ventilation device 41A is in the normal ventilation mode M1. On the other hand, as shown in FIG. 3B, the water supply switching unit 54 controls to supply water to the ventilation heat exchanger 42 when the ventilation device 41A is in the heat exchange ventilation mode M2.
　具体的に述べると、上記水供給切換部５４は、上記第３の熱動弁２６３（図１参照）の開閉を切り換えたり、上記ポンプ２３（図１参照）のオンオフを切り換えることで、換気用熱交換器４２への水の供給を制御する。 More specifically, the water supply switching unit 54 switches the opening and closing of the third thermal valve 263 (see FIG. 1) and switches the pump 23 (see FIG. 1) on and off, thereby ventilating. The supply of water to the heat exchanger 42 is controlled.
　したがって、上記水供給切換部５４によって、上記換気装置４１Ａが凍結する可能性がある熱交換換気モードＭ２のみで、上記換気用熱交換器４２に温水を供給できて、省エネに優れたものとなる。 Therefore, the water supply switching unit 54 can supply hot water to the ventilation heat exchanger 42 only in the heat exchange ventilation mode M2 in which the ventilation device 41A may be frozen, and is excellent in energy saving. .
　（第４の実施形態）
　図４は、この発明の第４実施形態の温調システムを示す。この第４の実施形態は、上記第１の実施形態とは、制御装置の構成のみが相違する。この相違する構成のみを以下に説明する。 (Fourth embodiment)
FIG. 4 shows a temperature control system according to a fourth embodiment of the present invention. The fourth embodiment is different from the first embodiment only in the configuration of the control device. Only this different configuration will be described below.
　図４に示すように、制御装置５０Ａは、モード選択部５５と外気温判定値設定部５６とモード別水供給制御部５７とを有する。モード別水供給制御部５７は、モード別液供給制御部の一例である。なお、図示しないが、上記制御装置５０Ａは、上記第１実施形態の上記第１の水温変更部５２を有するようにしてもよい。 As shown in FIG. 4, the control device 50A includes a mode selection unit 55, an outside air temperature determination value setting unit 56, and a mode-specific water supply control unit 57. The mode-specific water supply control unit 57 is an example of a mode-specific liquid supply control unit. Although not shown, the control device 50A may include the first water temperature changing unit 52 of the first embodiment.
　上記モード選択部５５は、凍結防止モードと暖房モードとを選択できる。上記凍結防止モードでは、上記換気装置４１（図１参照）が凍結しないように上記換気用熱交換器４２（図１参照）に供給される水を制御する。上記暖房モードでは、上記換気装置４１から室内へ吹き出される空気の温度が、上記凍結防止モードで上記換気装置４１から室内へ吹き出される空気の温度よりも高くなるように、上記換気用熱交換器４２に供給される水を制御する。 The mode selection unit 55 can select a freeze prevention mode and a heating mode. In the freeze prevention mode, the water supplied to the ventilation heat exchanger 42 (see FIG. 1) is controlled so that the ventilation device 41 (see FIG. 1) does not freeze. In the heating mode, the heat exchange for ventilation is performed such that the temperature of air blown into the room from the ventilator 41 is higher than the temperature of air blown into the room from the ventilator 41 in the freeze prevention mode. The water supplied to the vessel 42 is controlled.
　上記外気温判定値設定部５６は、上記暖房モードにおける、上記換気用熱交換器４２に供給される前の吸入外気の温度を判定するための第１の判定値を、上記凍結防止モードにおける、上記換気用熱交換器４２に供給される前の吸入外気の温度を判定するための第２の判定値よりも、大きく設定する。例えば、上記第１の判定値は、０℃であり、上記第２の判定値は、－１５℃である。 The outside air temperature determination value setting unit 56 determines a first determination value for determining the temperature of the intake outside air before being supplied to the ventilation heat exchanger 42 in the heating mode, in the freeze prevention mode. It is set to be larger than the second determination value for determining the temperature of the intake outside air before being supplied to the ventilation heat exchanger 42. For example, the first determination value is 0 ° C., and the second determination value is −15 ° C.
　上記モード別水供給制御部５７は、上記暖房モードにおいて、上記換気用熱交換器４２に供給される前の吸入外気の温度が、上記第１の判定値以下のとき、または、上記凍結防止モードにおいて、上記換気用熱交換器４２に供給される前の吸入外気の温度が、上記第２の判定値以下のときに、上記換気用熱交換器４２に水を供給するように制御する。具体的に述べると、モード別水供給制御部５７は、上記第３の熱動弁２６３（図１参照）を開けて、換気用熱交換器４２に温水を供給する。なお、モード別水供給制御部５７は、上記凍結防止制御部５１（図１参照）と同様に、上記換気ファン４１２が運転されたときの要件を追加するようにしてもよい。 The mode-specific water supply control unit 57 is configured such that, in the heating mode, the temperature of the intake outside air before being supplied to the ventilation heat exchanger 42 is equal to or lower than the first determination value, or the freeze prevention mode. Then, when the temperature of the outside intake air before being supplied to the ventilation heat exchanger 42 is equal to or lower than the second determination value, control is performed so that water is supplied to the ventilation heat exchanger 42. More specifically, the mode-specific water supply control unit 57 opens the third thermal valve 263 (see FIG. 1) and supplies hot water to the ventilation heat exchanger 42. The mode-specific water supply control unit 57 may add a requirement when the ventilation fan 412 is operated, similarly to the anti-freezing control unit 51 (see FIG. 1).
　したがって、ユーザは、上記モード選択部５５によって、換気装置４１の凍結防止の運転と、補助暖房の運転とを、選択できる。また、上記暖房モードでの換気装置４１から室内へ吹き出す空気の温度を、上記凍結防止モードでの換気装置４１から室内へ吹き出す空気の温度よりも、高くできて、ユーザが暖房モードを選択したとき、ユーザが冷たい風にあたる可能性をなくして、快適性を向上できる。 Therefore, the user can select the operation for preventing freezing of the ventilation device 41 and the operation for auxiliary heating by the mode selection unit 55. Further, when the temperature of the air blown into the room from the ventilator 41 in the heating mode can be higher than the temperature of the air blown into the room from the ventilator 41 in the anti-freezing mode, and the user selects the heating mode. The comfort of the user can be improved by eliminating the possibility of the user hitting a cold wind.
　（第５の実施形態）
　図５は、この発明の第５実施形態の温調システムを示す。この第５の実施形態は、上記第１の実施形態とは、制御装置の構成のみが相違する。この相違する構成のみを以下に説明する。 (Fifth embodiment)
FIG. 5 shows a temperature control system according to a fifth embodiment of the present invention. The fifth embodiment is different from the first embodiment only in the configuration of the control device. Only this different configuration will be described below.
　図５に示すように、制御装置５０Ｂは、モード選択部５５と水温設定部５８とモード別水供給制御部５９とを有する。水温設定部５８は、液温設定部の一例である。モード別水供給制御部５９は、モード別液供給制御部の一例である。なお、図示しないが、上記制御装置５０Ｂは、上記第１実施形態の上記第１の水温変更部５２を有するようにしてもよい。 As shown in FIG. 5, the control device 50B includes a mode selection unit 55, a water temperature setting unit 58, and a mode-specific water supply control unit 59. The water temperature setting unit 58 is an example of a liquid temperature setting unit. The mode-specific water supply control unit 59 is an example of a mode-specific liquid supply control unit. Although not shown, the control device 50B may include the first water temperature changing unit 52 of the first embodiment.
　上記モード選択部５５は、凍結防止モードと暖房モードとを選択できる。上記凍結防止モードでは、上記換気装置４１（図１参照）が凍結しないように上記換気用熱交換器４２（図１参照）に供給される水を制御する。上記暖房モードでは、上記換気装置４１から室内へ吹き出される空気の温度が、上記凍結防止モードで上記換気装置４１から室内へ吹き出される空気の温度よりも高くなるように、上記換気用熱交換器４２に供給される水を制御する。 The mode selection unit 55 can select a freeze prevention mode and a heating mode. In the freeze prevention mode, the water supplied to the ventilation heat exchanger 42 (see FIG. 1) is controlled so that the ventilation device 41 (see FIG. 1) does not freeze. In the heating mode, the heat exchange for ventilation is performed such that the temperature of air blown into the room from the ventilator 41 is higher than the temperature of air blown into the room from the ventilator 41 in the freeze prevention mode. The water supplied to the vessel 42 is controlled.
　上記水温設定部５８は、上記暖房モードでの上記換気用熱交換器４２に供給される水の第１の温度を、上記凍結防止モードでの上記換気用熱交換器４２に供給される水の第２の温度よりも、大きく設定する。 The water temperature setting unit 58 sets the first temperature of the water supplied to the ventilation heat exchanger 42 in the heating mode to the water supplied to the ventilation heat exchanger 42 in the freeze prevention mode. It is set larger than the second temperature.
　上記モード別水供給制御部５９は、上記暖房モードにおいて、上記換気用熱交換器４２に、上記第１の温度の水を供給し、または、上記凍結防止モードにおいて、上記換気用熱交換器４２に、上記第２の温度の水を供給するように制御する。具体的に述べると、モード別水供給制御部５９は、上記第３の熱動弁２６３（図１参照）の開度等が大きくなるように制御して、水の温度を高くする。なお、モード別水供給制御部５９は、上記凍結防止制御部５１（図１参照）と同様に、上記換気ファン４１２が運転されたときの要件を追加するようにしてもよい。 The mode-specific water supply control unit 59 supplies water at the first temperature to the ventilation heat exchanger 42 in the heating mode, or the ventilation heat exchanger 42 in the freeze prevention mode. Then, control is performed so that the water having the second temperature is supplied. Specifically, the mode-specific water supply control unit 59 increases the temperature of the water by controlling the opening degree of the third thermal valve 263 (see FIG. 1) to be large. The mode-specific water supply control unit 59 may add a requirement when the ventilation fan 412 is operated, similarly to the anti-freezing control unit 51 (see FIG. 1).
　したがって、ユーザは、上記モード選択部５５によって、換気装置４１の凍結防止の運転と、補助暖房の運転とを、選択できる。また、上記暖房モードでの換気装置４１から室内へ吹き出す空気の温度を、上記凍結防止モードでの換気装置４１から室内へ吹き出す空気の温度よりも、高くできて、ユーザが暖房モードを選択したとき、ユーザが冷たい風にあたる可能性をなくして、快適性を向上できる。 Therefore, the user can select the operation for preventing freezing of the ventilation device 41 and the operation for auxiliary heating by the mode selection unit 55. Further, when the temperature of the air blown into the room from the ventilator 41 in the heating mode can be higher than the temperature of the air blown into the room from the ventilator 41 in the anti-freezing mode, and the user selects the heating mode. The comfort of the user can be improved by eliminating the possibility of the user hitting a cold wind.

The hot water may be supplied based only on the hot water, or the hot water may be supplied according to a user instruction. Moreover, in the said embodiment, although the said 1st water temperature change part was provided, this may be abbreviate | omitted.
　また、上記二次側熱交換端末、上記換気装置および上記換気用熱交換器の数量を増減してもよく、この場合、二次側熱交換端末と換気用熱交換器とは、水熱交換器に並列に接続され、換気用熱交換器は、換気装置よりも吸入外気の上流側に、配置されていればよい。 In addition, the number of the secondary side heat exchange terminal, the ventilator, and the ventilation heat exchanger may be increased or decreased.
