置。 It is equipped with a refrigerant circuit consisting of a compressor 1, a four-way switching valve 2, a heat source side coil 3, a heating pressure reducing device 4, a cooling pressure reducing device 5, and a user side coil 6, and an electrical component box 11 containing electrical heating components. In a heat pump air-conditioning system, a bypass circuit 10 having an expansion valve 8 and an auxiliary cooler 9 connected in series is connected between a high-pressure liquid pipe and a low-pressure gas pipe of the refrigerant circuit. A portion of the refrigerant is depressurized by the expansion valve 8 so that it can flow to the auxiliary cooler 9, while the auxiliary cooler 9 is connected to the electrical component box 1.
The expansion valve 8 is attached to the expansion valve 8 in a heat exchangeable manner so that the reference refrigerant temperature of the auxiliary cooler 9 is maintained at a set value, and the auxiliary cooler 9 is attached during defrost operation. 1. A heat pump air-conditioning and heating system characterized in that an expansion valve control mechanism 12 is attached to the expansion valve 8 for forcibly changing the set value of the refrigerant reference temperature to a lower temperature side within a range where no condensation occurs.
