The present invention lessens the cost and the space used by a conventional air conditioning apparatus that is capable of both cooling and heating operations and can have an increased degree of supercooling for refrigerant flowing out from a condenser. The air conditioning apparatus (100) is provided with: a refrigeration cycle circuit (1) capable of both cooling and heating operations; and an internal heat exchanger (20) that has a first flow channel (21) through which refrigerant between an evaporator and a compressor (2) flows, a second flow channel (22) through which refrigerant between an outdoor heat exchanger (4) and an expansion unit (5) flows, and a third flow channel (23) through which refrigerant between the expansion unit (5) and an indoor heat exchanger (6) flows, and that is configured such that refrigerant flowing through the first flow channel (21) and refrigerant flowing through the second flow channel (22) are heat-exchanged during the cooling operation, and refrigerant flowing through the first flow channel (21) and refrigerant flowing through the third flow channel (23) are heat-exchanged during the heating operation. |
