An air conditioning apparatus includes a supercooling heat exchanger configured to exchange heat between a high-pressure refrigerant and a low-pressure refrigerant. A high-pressure liquid refrigerant pipe is wound around an external periphery of a low-pressure refrigerant suction pipe. Preferably, the supercooling heat exchanger is disposed inside the indoor unit at a position below an evaporator. Drain water from the evaporator is dispersed over the supercooling heat exchanger or a drain pipe leading from a drain pan of the evaporator is wound together with the high-pressure liquid refrigerant pipe around the low-pressure refrigerant suction pipe. In either case, cold energy of the drain water is made to effectively acts on the high-pressure liquid refrigerant pipe to exchange heat. The supercooling heat exchanger operates with improved efficiency without any increase in the volume of the heat exchanger so that the evaporator can be made as small and compact as possible.
