In order to eliminate the problem that the temperature of the surface of a radiant heat exchanger does not drop, the present invention is provided with a refrigerant circuit configured so that the refrigerant circuit can be switched between the mode of radiant heating operation in which radiant heating and heating by warm air are performed by causing a high-temperature refrigerant to flow to the radiant heat exchanger (34) of a radiant panel (30) and to an indoor heat exchanger, and the mode of heating operation using warm air in which heating by warm air is performed by causing a high-temperature refrigerant to flow to the indoor heat exchanger without causing the high-temperature refrigerant to flow to the radiant heat exchanger (34) of the radiant panel (30). The present invention is also provided with a trap section (36e) which, during the mode of heating operation using warm air, prevents the outflow of the liquid refrigerant within the radiant heat exchanger (34) of the radiant panel (30). |
