貯湯タンク23に貯湯を行う場合、循環ポンプ24が運転し、第1温水循環路C1では、貯湯タンク23→循環ポンプ24→水冷媒熱交換器14の水流路14B→流量調整弁25→貯湯タンク23の順に貯湯用の温水が流れ、貯湯タンク23に貯湯される。 If the hot water storage tank 23 performs the hot-water storage, circulation pump 24 is operated, the first hot-water circulation path C1, the hot water storage tank 23 → circulation pump 24 → water passage 14B of the water-refrigerant heat exchanger 14 → flow control valve 25 → hot water storage tank 23 hot water flows sequentially for the hot water storage of the hot water storage in the hot water storage tank 23.
【0029】 [0029]
ヒートポンプユニットAでは圧縮機13が運転すると共に第2開閉弁18が開き、冷媒回路Rでは、圧縮機13→水冷媒熱交換器14の一次流路14A→開閉弁18→第2膨張弁19→空気熱交換器20→内部熱交換器15の二次流路15B→アキュムレーター21→圧縮機13の順に冷媒が流れる。 Second on-off valve 18 with the heat pump unit A, the compressor 13 is operating is opened, the refrigerant circuit R, the compressor 13 → the primary flow path 14A of the water-refrigerant heat exchanger 14 → off valve 18 → the second expansion valve 19 → refrigerant flows in the order of the air heat exchanger 20 → the internal heat exchanger 15 the secondary flow path 15B → accumulator 21 → compressor 13. このとき、暖房は行われないので、第1開閉弁16及び第1膨張弁17は閉じており、第1分岐路P1には冷媒は流れない。 At this time, since the heating is not performed, the first on-off valve 16 and the first expansion valve 17 is closed, the first branch passage P1 refrigerant does not flow. また、内部熱交換器15の二次流路15Bでは冷媒がただ通過するだけで、他に影響を及ぼすことはない。 Also, just the refrigerant in the secondary flow path 15B of the internal heat exchanger 15 is only passed, it does not affect the other.
【0030】 [0030]
暖房運転の後などで、貯湯タンク23が一様温度となり、第1温水循環路C1において、水冷媒熱交換器14の二次流路14Bへ供給される温水の温度が仮に40℃以上となる場合には、第2開閉弁18及び第2膨張弁19を閉じ、第1開閉弁16及び第1膨張弁17を開ける。 Etc. After the heating operation, the hot water storage tank 23 becomes uniform temperature in the first hot-water circulation path C1, the temperature of the hot water if 40 ° C. or higher to be supplied to the secondary flow path 14B of the water-refrigerant heat exchanger 14 case, closes the second on-off valve 18 and the second expansion valve 19, opening the first on-off valve 16 and the first expansion valve 17. このとき、冷媒回路Rでは、床暖房運転や浴室暖房運転の場合と同様の冷媒循環経路となる。 At this time, in the refrigerant circuit R, the same refrigerant circulation path in the case of floor heating operation or bathroom heating operation.
【0031】 [0031]
貯湯タンク23へ供給される温水温度は90℃であるが、サーミスタ26が検知する温度がこの温度になるように、圧縮機13の周波数制御、第2膨張弁19(17)の弁開度制御、流量調整弁25の弁開度制御が行われる。 Although the hot water temperature supplied to the hot water storage tank 23 is 90 ° C., so that the temperature of the thermistor 26 detects becomes the temperature, the frequency control of the compressor 13, the valve opening control of the second expansion valve 19 (17) , the valve opening control of the flow rate adjusting valve 25 is performed.
【0032】 [0032]
貯湯タンク23に貯湯された高温水はミキシングバルブ36にて適度な温度に調整され、給湯管35から台所やシャワーへの給湯や浴槽34へのお湯張り等に利用される。 Hot water storage high temperature water in the hot water storage tank 23 is adjusted to appropriate temperature at the mixing valve 36, is available from the hot water supply pipe 35 to the hot water-covered or the like into the hot water supply or the bathtub 34 into the kitchen and showers. そして、給湯が行われると、給水管38から貯湯タンク23に給水が行われる。 When the hot water supply is performed, water is supplied from the water supply pipe 38 to the hot water storage tank 23.
【0033】 [0033]
また、開閉弁28を閉じると共に開閉弁30を開き、また循環ポンプ31、33を運転することにより、第3及び第5温水循環路C3、C5において、貯湯タンク23の高温水と浴槽34の温水を水々熱交換器29で熱交換し、浴槽34の温水の追い焚きを行うことができる。 Also open close valve 30 closes the on-off valve 28, also by operating the circulation pump 31 and 33, in the third and fifth hot water circulation path C3, C5, hot water of the hot water and tub 34 of the hot water storage tank 23 the heat exchange with water people heat exchanger 29, it is possible to perform the reheating of bathtub 34 hot water. この場合、前記第2温水循環路C2及び前記第3温水循環路C3内に温水を循環させる循環ポンプ31を共通のものを使用するから、部品点数も少なく、安価な装置となる。 Since this case uses a circulating pump 31 for circulating the hot water in the second water circulation pipe C2 and the third hot water circulation path C3 common ones, the number of components reduced and a low cost device.
【0034】 [0034]
〈暖房と貯湯の同時運転〉 <Simultaneous operation of heating and hot water storage>
この場合の暖房用温水の循環経路は上述したとおりである。 Circulation path of the heating hot water in this case is as described above. 冷媒回路Rでは、第1開閉弁16が開き、圧縮機13→水冷媒熱交換器14の冷媒流路14A→内部熱交換器15の一次流路15A→第1開閉弁16→第1膨張弁17→空気熱交換器20→内部熱交換器15の二次流路15B→アキュムレーター21→圧縮機13の順に冷媒が流れる。 In the refrigerant circuit R, the first on-off valve 16 is opened, the compressor 13 → the primary flow path 15A → the first on-off valve 16 → the first expansion valve in the refrigerant flow path 14A → the internal heat exchanger 15 of the water-refrigerant heat exchanger 14 17 → refrigerant flows in the order of the air heat exchanger 20 → the internal heat exchanger 15 the secondary flow path 15B → accumulator 21 → compressor 13. このとき、水冷媒熱交換器14及び内部熱交換器15で熱交換が行われるのは言うまでもない。 At this time, heat exchange with water-refrigerant heat exchanger 14 and the internal heat exchanger 15 is of course performed.
【0035】 [0035]
また、サーミスタ8、12、26においてそれぞれ上述した目標温度になるように、圧縮機13の周波数制御、第1膨張弁17の弁開度制御、流量調整弁25の弁開度制御が行われる。 Moreover, so that the target temperature mentioned above, respectively, in the thermistor 8,12,26, frequency control of the compressor 13, the valve opening degree control of the first expansion valve 17, the valve opening control of the flow rate adjusting valve 25 is performed. 同時運転が行われた場合には、圧縮機13は最大能力で運転するようにしてあり、暖房側と貯湯側とで十分な能力が得られるようにしてある。 When the simultaneous operation is performed, the compressor 13 is Yes so as to operate at maximum capacity, are so sufficient capacity can be obtained at the heating side and the hot water storage side.
