環路が形成されている。The evaporator 14 is located in the center of the evaporator unit 11, and is equipped with a condensation water tray 17 and a blower 15 at the bottom.The interior is vertically divided into two by a partition plate 18, with the left side being an outlet passage and the right side being a suction passage. It is a road. In addition, the switching plate 11 is a partition plate 18
A switching plate 18a is provided on the outlet passage side by a shaft 19 passing through the
Further, a switching plate 16b is provided on the suction path side, and the motor 20
It is configured to rotate by. A duct 21 penetrates the wall and communicates with the indoor side, and a blow-off grill 22 is attached to the tip of the duct 21. The inside of the duct 21 is also divided into two parts corresponding to the partition plate 18, and the left side of one outlet grille 18 is an indoor suita port 23, and the right side is an indoor suction port 24. In this way, the first air circulation path is formed.

また、運転中に蒸発器１４に霜がついた時、これを除霜
するためのバイパス弁２８も設けられている。Furthermore, a bypass valve 28 is also provided for defrosting the evaporator 14 when it becomes frosted during operation.
上記構成において、次にその動作を説明する。The operation of the above configuration will now be described.

液冷媒となる。First, to describe the cooling waste heat hot water supply operation in summer, the switching plate 16 of the evaporator unit 11 is switched to the first air circulation path side. When the operation switch 29 is turned to ○, high-temperature and high-pressure refrigerant gas is sent from the compressor 1 to the hot water supply heat exchanger 3, where it exchanges heat with the water sent by the circulation pump 9 and condenses.
It becomes a liquid refrigerant.

を繰り返す。This liquid refrigerant is depressurized through the expansion valve 10, becomes a low-temperature liquid refrigerant, and is sent to the evaporator 14. The evaporator unit 11 sucks air through the indoor suction port 24, sends this air to the evaporator 14 using the blower 15 for cooling, and blows out cold air to the indoor air outlet 23 for cooling. Due to the heat exchange at this time, the liquid refrigerant evaporates in the evaporator 14 and is transferred to the compressor 1 where the circulation is repeated.

熱を外部に放出するようにしている。Then, the water temperature in the hot water supply storage tank 8 is gradually raised. Note that if the cooling operation continues after the set water temperature has been reached, the condensation pressure will become too high, so the water temperature sensor 13
detects this and opens the solenoid valve 12 to drain the hot water from the top. Then, low-temperature water is supplied from the lower part, and when the water temperature sensor 13 detects a predetermined water temperature, the electromagnetic valve 12 is closed to release waste heat from cooling to the outside.

ようにしている。Next, we will discuss heat pump hot water supply operation outside of summer. When the switching plate 16 is rotated to switch to the second air circulation path side, outdoor air is sucked in from the outdoor suction port 26, sent to the evaporator 14 by the blower 15, and then released to the outside from the outdoor Suita port 25. . At this time, the refrigerant in the evaporator 14 is evaporated and absorbed by the heat of the atmosphere, heating the place.
