プ。 From the compressor to the first three-way switching valve, condenser, expansion valve,
A heat recovery operation flow path for the refrigerant that returns to the compressor via the second three-way switching valve, the evaporator, and the third three-way switching valve, and the condenser via the first three-way switching valve, the air heat exchanger, and the check valve. A heat dissipation flow path for the refrigerant, which shares a portion with both of the flow paths, connects the compressor to the first three-way switching valve, the condenser, the expansion valve, the second three-way switching valve, and the air heat exchanger to the above. A heating operation flow path for refrigerant returning to the compressor via a third three-way switching valve, and a temperature controller provided on the outlet side of the heat exchanger in the condenser,
This temperature controller switches the first three-way switching valve, and when the temperature detected by this temperature controller is lower than the set value, the heat recovery operation flow path is opened, and when the detected temperature is higher than the set value, the heat recovery operation flow path is opened. In some cases, in the heat pump formed to open the heat radiation flow path, a bypass flow path that communicates the inside of the condenser of the heat recovery operation flow path with the suction side of the compressor via an on-off valve; differential pressure detection means for detecting the differential pressure between the pressure in the condenser and the air heat exchanger inlet pressure of the heat radiation flow path; A control means is provided for opening the on-off valve and switching to the first three-way switching valve side only until the differential pressure detection means detects that the pressure in the condenser has become smaller. Features of heat pump.
