An air conditioner provided with a heat-pump system refrigerating cycle including a compressor, an outdoor heat exchanger, an expansion valve, an indoor heat exchanger installed within a room, and a radiation type heat exchanger connected in a circuit. An indoor unit includes the indoor heat exchanger, the radiation type heat exchanger displaced in a state exposed to the room and an indoor fan. A selector is provided to select between a warm-air heating during which the indoor fan is turned on and a radiant heating during which the indoor fan is turned off. The capacity of the compressor during the radiant heating mode is adjusted below the capacity during the warm-air heating mode.
