Air-conditioning apparatus

摘要

To reduce pressure loss of refrigerant while suppressing a cost increase.;[Solution] In an air-conditioning apparatus 100 having a compressor 201, a radiator 204 (301), an expansion device 302, and an evaporator 301 (204), which are connected by a refrigerant pipe to form a refrigeration cycle, at least a part of the refrigerant pipe (207, 208, 209, 210, 211, 212) that connects from the suction side of the compressor 201 to the evaporator 301 (204) is configured by a plurality of pipes connected in parallel, and a refrigerant that flows through the refrigeration cycle is a tetrafluoropropene-based refrigerant or a refrigerant mixture having tetrafluoropropene as a main component.
