Refrigeration unit

摘要

In a refrigeration unit 4 disposed in a machine room 3 of a refrigerator or the like, an expansion valve cover 11 and a pressure switch mounting plate 12 are disposed in the side of a refrigerant compressor 8 placed behind a fan motor 6, and at positions which are in a lateral side of the refrigerant compressor 8 and separated therefrom by a gap, and which are deviated from the direction along which cooling air from the fan motor 6 is ejected. The cover and the plate are disposed so as to elongate in substantially parallel with a side face of the refrigerant compressor 8. A cooling air passage 20 is formed in each of both the sides of the refrigerant compressor 8.
