<p>[Problem] To reduce pressure loss for the cooling medium while suppressing an increase in cost. [Solution] An air conditioner (100) having a compressor (201), radiators (204 (301)), a throttling device (302) and evaporators (301 (204)), with these being connected by cooling medium pipes to form a refrigeration cycle, wherein at least a portion of the cooling medium pipes (207, 208, 209, 210, 211, 212) forming the connection from the suction side of the compressor (201) to the evaporators (301 (204)) comprises multiple pipes connected in parallel, and the cooling medium flowing in the refrigeration cycle is a tetra-fluoropropene series cooling medium or a mixed cooling medium the main component of which is tetra-fluoropropene.</p> |
