2 is a heat exchanger for hot water supply, and a heat exchange coil 3 for hot water supply is provided in the vessel. 4 is an air-side heat exchanger provided downstream of the hot water supply heat exchanger 2 and has a blower 5; 6 is an air-side heat exchanger provided in the piping between the hot water supply heat exchanger 2 and the refrigerant temperature on the outlet side of the hot water supply heat exchange coil 3; Alternatively, a detector 7 detects pressure and controls the blower 5, and 7 is an expansion device that expands the refrigerant. Reference numeral 8 denotes an air conditioning heat exchanger, and an air conditioning heat exchange coil 9 is provided in the vessel. 10 is a hot water supply tank; 11 is a hot water supply pump that supplies water in the hot water supply tank to the hot water heat exchanger 2;
2 is a hot water faucet installed in the hot water tank 10; 13 is a tank for supplying water to the hot water tank; 14 is a water pipe;
15 is an auxiliary electric heater provided in the hot water supply tank 10, 16 is an air conditioning pump that supplies cooling water from the air conditioning heat exchanger 8 to the indoor heat exchanger 17, and 18 is an air conditioning expansion tank. . In this configuration, the high temperature, high pressure gas discharged from the compressor 1 is heat exchanged by the hot water supply heat exchange coil 3, and the water in the hot water supply heat exchanger 2 is heated. This heated water is circulated between the hot water supply tank 10 and the hot water supply heat exchanger 2 by the hot water supply pump 11.

機５の運転により凝縮作用は空気側熱交換器４内
でなされるので、凝縮圧力は正常に戻る。 When the water temperature in the hot water supply tank 10 is low, the hot water supply heat exchange coil 3 acts as a condenser, and the condensed refrigerant passes through the downstream air side heat exchanger 4 because the blower 5 is stopped and expands. It reaches the device 7, where it expands under reduced pressure, reaches the air conditioning heat exchange coil 9, and evaporates. At this time, the water in the air conditioning heat exchanger 8 is cooled. This cooled water is sent to the indoor heat exchanger 17 by the air conditioning pump 16 and is used to cool the room. In this way, the hot water supply heat exchange coil 3 is used as a condenser to cool the room, but if this operation continues,
As the temperature of the hot water supply water increases, the temperature or condensation pressure of the refrigerant in the hot water supply heat exchange coil increases, so this is detected by the detector 6 and the temperature is Controls the blower 5. By operating the blower 5, the condensing action is performed within the air side heat exchanger 4, so that the condensing pressure returns to normal.
一方給湯用熱交換コイル３では、吐出冷媒ガス
の温度の高い部分（約120〜160℃）のみが熱交換
されるので、温水温度の上昇は凝縮温度を上昇さ
せることなく得られる。更に高い温水を必要とす

ヒータ１５によつて得られる。 On the other hand, in the hot water supply heat exchange coil 3, only the high temperature portion (approximately 120 to 160° C.) of the discharged refrigerant gas is heat exchanged, so that the hot water temperature can be increased without increasing the condensation temperature. If even higher hot water is required, it can be obtained by an auxiliary electric heater 15 provided in the hot water tank 1.
