収運転を行う。(Space below) Table 1 ○ mark; Valve open x mark; Valve closed When starting operation in each operation mode of heating operation, hot water storage/cool storage operation, and cold storage heat recovery operation, the refrigerant power in the refrigerant circuit necessary for operation will be dispersed in the heat exchanger and refrigerant circuit in the refrigerant circuit. If the refrigerant leaks from the solenoid valve while the operation continues in each operation mode, it accumulates in the unused heat exchanger, making it impossible to continue stable operation. Therefore, the present invention provides a method for controlling the operation of a heat pump type air conditioning/heating water heater that solves the above-mentioned problems by performing a refrigerant recovery operation for starting and continuing operation in each operation mode of the heat pump type air conditioning/heating water heater. A heat pump air-conditioning/heating water heater according to the present invention (which performs a refrigerant recovery operation to a compressor at the start of each operation mode and at the time of continuous operation). According to the above configuration, the amount of refrigerant in the refrigerant circuit can be optimally controlled in each operation mode of the heat pump type air-conditioning/heating water heater to ensure stable operation. This is a refrigerant circuit diagram of a heat pump air-conditioning/heating water heater which is also used as an embodiment of the present invention, and the solenoid valve control in each operation mode is shown in the table above. l is a compressor, 2 is a four-way valve, 3 is an indoor heat exchanger, 4 is an expansion valve, 5

When the operation starts, the supply of refrigerant and refrigeration oil to the compressor 1 becomes insufficient, which may cause overheating of the compressor and unstable operation. In addition, when operating continuously in each operation mode, refrigerant gradually leaks from the solenoid valve even when the solenoid valve is closed, and accumulates in the heat exchanger. This causes overheating of the compressor 1 and unstable operation. Therefore, when starting operation in each operation mode, the solenoid valve control shown in Table 2 is performed for a certain predetermined time (＼
A refrigerant recovery operation is performed to recover the refrigerant and refrigeration machine oil into the compressor 1.
