摘要

The objective of the present invention is to prevent corrosion of aluminum liquid pipes and aluminum gas pipes extending from an aluminum heat exchanger. An aluminum heat-exchanger-side gas pipe (31) for circulating gaseous refrigerant and an aluminum heat-exchanger-side liquid pipe (32) for circulating liquid refrigerant extend from the side of an aluminum outdoor heat exchanger (20). The heat-exchanger-side liquid pipe (32) extends from the side of the outdoor heat exchanger (20) below the heat-exchanger-side gas pipe (31). The aluminum heat-exchanger-side gas pipe (31) is connected to a copper gaseous refrigerant pipe (41) from above the copper gaseous refrigerant pipe (41). The aluminum heat-exchanger-side liquid pipe (32) is arranged in a region other than the region directly below the connecting part (45) between the heat-exchanger-side gas pipe (31) and the copper gaseous refrigerant pipe (41).
