PROBLEM TO BE SOLVED: To solve the problem that the evaporation temperature difference between evaporation side heat exchangers of two refrigerant circuits is increased, and dew is easily generated in an indoor unit in an air-conditioner of two-refrigerant circuit configuration having a compressor of variable displacement and a constant speed compressor of fixed displacement. SOLUTION: This air conditioner has a bypass circuit having a throttling device which is bypassed to an intake side of the compressor of fixed displacement from a part between a condensation side heat exchanger and the throttling device of a refrigerant circuit on the fixed displacement side, and a supercooling heat exchanger to exchange heat between a refrigerant in the bypass circuit and a refrigerant in a liquid line between a condensation side heat exchanger and a throttling device of a refrigerant circuit on the variable displacement side.
