PROBLEM TO BE SOLVED: To provide a refrigerant circuit unit with which a foam insulation material can be filled completely in clearances inside of a main case and in corners of the main case and deformation of the main case can be prevented while attaining a compact size of the refrigerant circuit.SOLUTION: A switching unit is provided with a main case 10 formed in a box shape comprising at least an upper case and a lower case storing a refrigerant piping unit. Cylinder parts 402, 412, ... which are included in a valve body of an on-off valve are guided from the front face of the main case 10, and electromagnetic coils are attached to the cylinder parts 402, 412, .... Refrigerant piping 33, 34 connected to the piping extended from an indoor unit are guided from a back face of the main case. The upper case and the lower case each includes the same number of partition plates 17, 18. The partition plates 17, 18 overlap to each other and partition inside the main case 10 in a manner to form a plurality of spaces in the right and left direction of the main case 10. |
