PROBLEM TO BE SOLVED: To save the space around an expansion valve. SOLUTION: By corresponding to the mounting position of an expansion valve 4 for an evaporator 5, the position relationship between the expansion valve 4, a compressor, and a condenser, or the like, the axial direction of a channel communicating with the evaporator 5, and that of a channel communicating with the compressor and the condenser cross each other, thus eliminating the need for the bending of piping near the expansion valve 4, and saving space around the expansion valve 4 by length from the end part of the piping due to the bending to a bending part.
