40は運転制御手段としての制御装置で、この制御装置40は、第１の三方弁22、第２の三方弁26、流量調整弁25、循環ポンプ23、暖房用循環ポンプ38を適宜制御するとともに、ヒートポンプユニット13を動作させ、貯湯槽15の水の沸上制御を行なったり、貯湯槽15内の水の沸き上げを行ないながら暖房運転を行なったり、朝の立ち上がり時に貯湯槽15内の沸き上がった湯水を貯湯槽15の上部より取出し速暖運転を行なったりするようになっている。 Reference numeral 40 denotes a control device as operation control means. The control device 40 appropriately controls the first three-way valve 22, the second three-way valve 26, the flow rate adjusting valve 25, the circulation pump 23, and the heating circulation pump 38. The heat pump unit 13 is operated to control the boiling of the water in the hot water tank 15, the heating operation is performed while boiling the water in the hot water tank 15, or the hot water in the hot water tank 15 is boiled at the start of the morning. The hot water is taken out from the upper part of the hot water storage tank 15, and a rapid heating operation is performed.
そして、このように構成されたヒートポンプ給湯暖房装置は、図４に示されるように貯湯槽15内の水を沸上げる。 And the heat pump hot-water supply / room heating apparatus comprised in this way boils the water in the hot water storage tank 15 as FIG. 4 shows.
すなわち、給水管17から減圧弁16を介して貯湯槽15内に水道水が貯留される。そして、図示しないリモコン等の操作により制御装置40が制御され、第１の三方弁22、第２の三方弁26が沸上用循環路21側に切り換えられるとともに、流量調整弁25が沸上用循環路21側に１００％の水が流れるように調整される。そして、電気料金の安い深夜電力時間帯において、ヒートポンプユニット13の圧縮機28が駆動される。これにより矢印で示すように、冷媒は、圧縮機28、凝縮器として機能する冷媒熱交換器29、膨張弁30、蒸発器31の順に流れる。一方、送風モータ33が駆動され送風ファン32が回転して蒸発器31に大気熱を集熱させ、この集熱された熱により気化された冷媒は圧縮機28に送られ、圧縮機28で圧縮されて出た高温高圧の冷媒ガスは、冷媒熱交換器29で熱交換される。 That is, tap water is stored in the hot water tank 15 from the water supply pipe 17 through the pressure reducing valve 16. Then, the control device 40 is controlled by the operation of a remote controller or the like (not shown), the first three-way valve 22 and the second three-way valve 26 are switched to the boiling circulation path 21 side, and the flow rate adjusting valve 25 is used for boiling. It is adjusted so that 100% of water flows to the circulation path 21 side. Then, the compressor 28 of the heat pump unit 13 is driven in the late-night power hours when the electricity rate is low. As a result, as indicated by arrows, the refrigerant flows in the order of the compressor 28, the refrigerant heat exchanger 29 functioning as a condenser, the expansion valve 30, and the evaporator 31. On the other hand, the blower motor 33 is driven and the blower fan 32 rotates to collect atmospheric heat in the evaporator 31, and the refrigerant vaporized by the collected heat is sent to the compressor 28 and compressed by the compressor 28. The high-temperature and high-pressure refrigerant gas thus produced is heat-exchanged by the refrigerant heat exchanger 29.
一方、循環ポンプ23が駆動され、矢印で示すように貯湯槽15内の水が水熱交換器24に強制的に引き込まれ冷媒熱交換器29との間で熱交換され湯水となって貯湯槽15上部に入り、これを繰返して貯湯槽15の上部から設定温度の約８０℃の湯水が順次積層され貯湯槽15内の水が沸上げられる。そして、このように貯湯槽15内に積層された湯水は給湯管18を通じてミキシングバルブ19に送られ、給水管17からの水と混合され適温となって台所や浴槽の給湯用として用いられる。 On the other hand, the circulation pump 23 is driven, and the water in the hot water storage tank 15 is forcibly drawn into the water heat exchanger 24 as indicated by an arrow, and heat is exchanged with the refrigerant heat exchanger 29 to become hot water. 15. Entering the upper part 15 is repeated, and hot water of a set temperature of about 80 ° C. is sequentially laminated from the upper part of the hot water tank 15 to boil the water in the hot water tank 15. The hot water stacked in the hot water storage tank 15 in this way is sent to the mixing valve 19 through the hot water supply pipe 18, mixed with the water from the water supply pipe 17, and used for hot water supply in the kitchen and bathtub.
また、ヒートポンプ給湯暖房装置は、図５に示されるように貯湯槽15の水を沸上げながら暖房運転が行なわれる。 In addition, the heat pump hot water supply / heating device is heated while boiling water in the hot water storage tank 15 as shown in FIG.
すなわち、図示しないリモコン等の操作により沸上暖房運転が選択され、制御装置40の制御により、第１の三方弁22、第２の三方弁26が沸上用循環路21側に切り換えられるとともに、流量調整弁25が沸上用循環路21側と暖房用循環路34側の両方に水が流れるように制御される。 That is, boiling heating operation is selected by operation of a remote controller (not shown), and the first three-way valve 22 and the second three-way valve 26 are switched to the boiling circulation path 21 side by the control of the control device 40. The flow rate adjustment valve 25 is controlled so that water flows through both the boiling circuit 21 side and the heating circuit 34 side.
そして、ヒートポンプユニット13の圧縮機28が沸上運転時よりも高出力で駆動される。これにより、冷媒は沸上運転と同様に冷媒循環路27内を流通し、蒸発器31で大気熱を集熱し気化された冷媒は圧縮機28に送られ、圧縮機28で圧縮されて出た高温高圧の冷媒ガスは、冷媒熱交換器29で水熱交換器24と熱交換されることになる。 Then, the compressor 28 of the heat pump unit 13 is driven at a higher output than in the boiling operation. As a result, the refrigerant circulates in the refrigerant circulation path 27 in the same manner as the boiling operation, and the vaporized refrigerant that collects atmospheric heat by the evaporator 31 is sent to the compressor 28 and is compressed by the compressor 28. The high-temperature and high-pressure refrigerant gas is heat-exchanged with the water heat exchanger 24 in the refrigerant heat exchanger 29.
一方、沸上用循環路21の循環ポンプ23が駆動され、矢印で示すように貯湯槽15下部から出た水が第１の三方弁22、循環ポンプ23、水熱交換器24と流れ、水熱交換器24と冷媒熱交換器29との間で熱交換され湯水となり、この湯水が流量調整弁25で分流され、その一部が貯湯槽15の上部に入り、これを繰り返して貯湯槽15の上部から設定温度約８０℃の湯水が順次積層され貯湯槽15内の水が沸上げられる。 On the other hand, the circulation pump 23 of the boiling circulation path 21 is driven, and the water discharged from the lower part of the hot water tank 15 flows through the first three-way valve 22, the circulation pump 23, and the water heat exchanger 24 as shown by the arrows, Heat is exchanged between the heat exchanger 24 and the refrigerant heat exchanger 29 to become hot water, and this hot water is divided by the flow rate adjustment valve 25, a part of which enters the upper portion of the hot water tank 15, and this is repeated to make the hot water tank 15 Hot water with a set temperature of about 80 ° C. is sequentially laminated from above the water to boil the water in the hot water storage tank 15.
また、流量調整弁25で分流された他の一部の湯水は暖房用循環路34に流れる。そして、暖房用循環ポンプ38が駆動され暖房用循環路34内の熱媒は暖房用循環路34内を矢印のように循環し、この熱媒は暖房用熱交換器36で熱交換されて暖房パネル37より放熱されて暖房に供される。 Further, some other hot water divided by the flow rate adjusting valve 25 flows into the heating circulation path 34. Then, the heating circulation pump 38 is driven, and the heating medium in the heating circulation path 34 circulates in the heating circulation path 34 as indicated by an arrow, and this heating medium is heat-exchanged by the heating heat exchanger 36 and heated. Heat is radiated from the panel 37 and used for heating.
また、朝方の暖房初期運転は暖房運転の立ち上がりの速さが要求され、そのため、貯湯槽15内上部の沸き上げられた湯水の熱が利用される。すなわち、図６に示されるように図示しないリモコン等の操作により速暖運転が選択されると制御装置40により、第１の三方弁22及び第２の三方弁26が第１の速暖用循環路39側に切り換え制御されるとともに、流量調整弁25が第１の速暖用循環路39側に１００％の量の湯水が流れるように調整され第１の速暖用循環路39が形成される。そして、循環ポンプ23が駆動され貯湯槽15の上部より貯湯槽15内の湯水が第２の三方弁26、第１の三方弁22、水熱交換器24、流量調整弁25、暖房用熱交換器36、貯湯槽15下部へと循環される。 Further, the early heating operation in the morning requires a rapid start-up of the heating operation. For this reason, the heat of the hot water heated in the upper part of the hot water tank 15 is used. That is, as shown in FIG. 6, when the quick warm-up operation is selected by an operation of a remote controller (not shown), the control device 40 causes the first three-way valve 22 and the second three-way valve 26 to circulate in the first quick warm-up cycle. The flow control valve 25 is adjusted so that 100% of hot water flows to the first speed heating circulation path 39 side, and the first speed heating circulation path 39 is formed. The Then, the circulation pump 23 is driven, and the hot water in the hot water tank 15 is supplied from the upper part of the hot water tank 15 to the second three-way valve 26, the first three-way valve 22, the water heat exchanger 24, the flow rate adjusting valve 25, and the heat exchange for heating. It is circulated to the lower part of the vessel 36 and the hot water tank 15.
一方、暖房ユニット14の暖房用循環ポンプ38が駆動され暖房用熱媒循環路35内の熱媒が循環される。そして、第１の速暖用循環路39内を流通する約８０℃の湯水の熱が暖房用熱交換器36ですぐに熱交換され暖房パネル37より放熱されて暖房初期運転が行われる。 On the other hand, the heating circulation pump 38 of the heating unit 14 is driven to circulate the heat medium in the heating medium circulation path 35. Then, the heat of hot water of about 80 ° C. flowing through the first rapid heating circuit 39 is immediately heat-exchanged by the heating heat exchanger 36 and radiated from the heating panel 37, so that the heating initial operation is performed.
このように、従来のヒートポンプ給湯暖房装置では、深夜電力時間帯に貯湯槽内の水を沸き上げながら暖房運転を行なったり、深夜電力時間帯に沸き上げた湯水を使用して朝方の速暖運転を行なうことができた。しかし、深夜電力時間帯に湯水を多量に使用した等貯湯槽内の湯水の量が不足している場合にすぐに速暖運転ができない問題があった。 In this way, in the conventional heat pump hot water heater / heater, heating operation is performed while boiling water in the hot water tank during the late-night power hours, or rapid heating operation in the morning using hot water heated during the late-night power hours Could be done. However, there is a problem that rapid heating operation cannot be performed immediately when the amount of hot water in the hot water storage tank is insufficient, such as when a large amount of hot water is used during the midnight power hours.
本発明は、このような点に鑑みなされたもので、貯湯槽内の湯水の量が不足している場合であっても、貯湯槽内の湯水を使用せずにすぐに速暖運転ができるヒートポンプ給湯暖房装置を提供することを目的とする。 The present invention has been made in view of the above points, and even when the amount of hot water in the hot water tank is insufficient, quick heating operation can be performed immediately without using hot water in the hot water tank. An object of the present invention is to provide a heat pump water heater / heater.

The refrigerant heat exchanger 29 exchanges heat with the water heat exchanger 24.
一方、循環ポンプ23が駆動され、矢印で示すように第２の速暖用循環路41内に滞留している湯水が第２の速暖用循環路41内を循環する。そして、この第２の速暖用循環路41内に循環する湯水は水熱交換器24と冷媒熱交換器29との間で熱交換されて加熱される。 On the other hand, the circulation pump 23 is driven, and hot water staying in the second rapid warming circuit 41 circulates in the second rapid warming circuit 41 as indicated by an arrow. Then, the hot water circulating in the second quick heating circuit 41 is heated by heat exchange between the water heat exchanger 24 and the refrigerant heat exchanger 29.
また、水熱交換器24と冷媒熱交換器29との間で熱交換されて加熱された湯水の熱が暖房用熱交換器36で暖房用熱媒循環路35内の熱媒と熱交換されることとなる。そして、暖房用循環ポンプ38が駆動され暖房用循環路34内の熱媒は暖房用循環路34内を矢印のように循環し、暖房パネル37より放熱されて速暖運転が行われる。 Further, the heat of the hot water heated by the heat exchange between the water heat exchanger 24 and the refrigerant heat exchanger 29 is exchanged with the heat medium in the heating medium circulation path 35 by the heating heat exchanger 36. The Rukoto. Then, the heating circulation pump 38 is driven, and the heat medium in the heating circulation path 34 circulates in the heating circulation path 34 as indicated by an arrow, and is radiated from the heating panel 37 to perform a quick heating operation.
