By setting the second and third switches 13 and 14 to the "closed" position, the high-temperature refrigerant discharged from the compressor 1 flows in the order of the radiant panel 3, the first pressure reducer 4, and the indoor heat exchanger 6. At the same time, a portion of the high temperature refrigerant discharged from the compressor 1 is passed through the bypass circuit 13.
a, flows to the second pressure reducer 8 via the outdoor heat exchanger 10, and is depressurized. Then, this depressurized refrigerant joins the refrigerant from the indoor heat exchanger 6 and enters the bypass circuit 14.
The air is sucked into the compressor 1 via a. therefore,
The radiant panel 3 and the outdoor heat exchanger 10 can be used as a condenser, and the indoor heat exchanger 6 can be used as an evaporator.
It is possible to balance heat radiation and heat absorption, and the reliability of the refrigeration cycle can be improved.
