It is connected to the top of the hot water storage tank 12.

２７は前記ヒートポンプ側制御装置８とタンク側制御装置２６とを配線接続する通信線、２８は台所用リモートコントローラ、２９は風呂用リモートコントローラであり、これら各リモートコントローラ２８、２９はタンク側制御装置２６に配線接続されている。３０は風呂を示している。 27 is a communication line for wiring connection between the heat pump side control device 8 and the tank side control device 26, 28 is a kitchen remote controller, 29 is a bath remote controller, and these remote controllers 28 and 29 are tank side control devices. 26 is connected by wiring. 30 indicates a bath.

ここで、台所などに設置してある蛇口（図示せず）を開けると、貯湯タンク１２内上部の高温の湯が水道圧で給湯用配管２３へ押し出され、給湯が行われると同時に、貯湯タンク１２内下部には、底部に接続された水道配管１３から水道水が給水される。 Here, when a faucet (not shown) installed in the kitchen or the like is opened, the hot water in the upper part of the hot water storage tank 12 is pushed out to the hot water supply pipe 23 by water pressure, and at the same time as hot water is supplied, Tap water is supplied to the lower part in 12 from a water pipe 13 connected to the bottom.

風呂３０に注湯する湯張りを行う場合は、風呂用リモートコントローラ２９の風呂湯張りスイッチ（図示せず）を押すと、貯湯タンク１２内上部から給湯用配管２３へ押し出された高温の湯が混合弁装置２４へ流れ、ここで分岐給水管１５から給水される水と混合されて、予め設定された温度の湯が風呂３０へ注湯され、所定の湯量が注湯されると湯張りが完了する。この風呂３０の湯張り時にも、湯張り運転の開始と同時に、貯湯タンク１２内下部には、底部に接続された水道配管１３から水道水が給水される。 When filling the bath 30 with hot water, if a bath hot water switch (not shown) of the remote controller 29 for bath is pressed, hot water pushed out from the upper part of the hot water storage tank 12 to the hot water supply pipe 23 is heated.

Even when the bath 30 is filled, tap water is supplied to the lower part of the hot water storage tank 12 from the water pipe 13 connected to the bottom at the same time as the start of the filling operation.

上記したように台所や風呂３０などの利用部への給湯が行われると、貯湯タンク１２内の高温の湯が消費され、貯湯タンク１２内における高温の湯の層が減少し、この高温の湯は貯湯タンク１２内の上部にのみ貯留し、貯湯タンク１２内の中間部や下部は、温度の低い湯或いは水が貯留された状態となる。 As described above, when hot water is supplied to a use section such as the kitchen or the bath 30, the hot water in the hot water storage tank 12 is consumed, and the hot water layer in the hot water storage tank 12 is reduced. Is stored only in the upper part of the hot water storage tank 12, and the intermediate part and the lower part of the hot water storage tank 12 are in a state where hot water or water having a low temperature is stored.

次に、お湯の沸き上げ運転について説明する。ヒートポンプユニット１の運転開始により、ヒートポンプサイクルＸの圧縮機３が起動すると、二酸化炭素の冷媒が圧縮機３によって２段圧縮され、この圧縮機３で圧縮されて吐出した超臨界圧の高温・高圧の液状の冷媒は放熱器４Ａで放熱して受熱器４Ｂを流れる水と熱交換し、その水を加熱する。 Next, hot water boiling operation will be described. When the compressor 3 of the heat pump cycle X is started by starting the operation of the heat pump unit 1, the carbon dioxide refrigerant is compressed in two stages by the compressor 3, and is compressed and discharged by the compressor 3. The liquid refrigerant radiates heat with the radiator 4A, exchanges heat with water flowing through the heat receiver 4B, and heats the water.

前記放熱器４Ａで放熱して温度の低下した冷媒は、減圧装置５で減圧されて低圧となった後、蒸発器６に流れ、蒸発器６で空気から吸熱して蒸発し、低温・低圧のガス状の冷媒となり、アキュームレータ７に流れ、このアキュームレータ７から圧縮機３に吸入され再び圧縮される。 The refrigerant whose temperature has been reduced by releasing heat from the radiator 4A is reduced in pressure by the decompression device 5 and becomes low pressure, and then flows into the evaporator 6 and is evaporated by absorbing heat from the air in the evaporator 6. It becomes a gaseous refrigerant, flows into the accumulator 7, is sucked into the compressor 3 from the accumulator 7, and is compressed again.

上述のヒートポンプユニット１の運転開始に伴い、貯湯タンクユニット２内の貯湯用循環ポンプ１７が起動し、この循環ポンプ１７の運転により、前記貯湯タンク１２内下部の低温或いは常温の水が、貯湯用配管１６の出口部１６Ａから貯湯用配管１６内へ流れ、貯湯用循環ポンプ１７を介して受熱器４Ｂへ流れ、ここで前記放熱器４Ａを流れる高温・高圧の冷媒と熱交換して加熱される。そして、この受熱器４Ｂで加熱された高温の湯は前記入口部１６Ｂから貯湯タンク１２内の上部に流入し、沸き上げ運転の時間の経過に伴って、貯湯タンク１２内には８０℃以上の湯の貯留量が徐々に増加し、この高温の湯の湯層が貯湯タンク１２内の下部に至ると沸き上げ運転が完了する。 With the start of operation of the heat pump unit 1, the hot water circulation pump 17 in the hot water storage tank unit 2 is activated, and the operation of the circulation pump 17 causes the low or normal temperature water in the lower part of the hot water storage tank 12 to be used for hot water storage. It flows into the hot water storage pipe 16 from the outlet 16A of the pipe 16, flows into the heat receiver 4B through the hot water circulation pump 17, and is heated by exchanging heat with the high-temperature and high-pressure refrigerant flowing through the radiator 4A. . And the hot water heated by this heat receiver 4B flows into the upper part of the hot water storage tank 12 from the said inlet part 16B, and 80 degreeC or more is contained in the hot water storage tank 12 with progress of the time of boiling operation. When the hot water storage amount gradually increases and the hot water layer reaches the lower part of the hot water storage tank 12, the boiling operation is completed.
