2, and the remaining refrigerant flows in parallel to the indoor heat exchanger 3 provided in parallel with the floor radiator 6. Then, they merge at the outlet of the two, and the electromagnetic on-off valve 8,
A refrigeration cycle is constructed in which the refrigerant is heated by the refrigerant heater 7 and returned to the compressor 1. Note that the indoor heat exchanger 3 radiates heat into the room by the blower 9.
