COMPRESSOR FOR REFRIGERATION MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/021442
Kind Code:
A1
Abstract:
A compressor (5A) comprising a casing (10), a compression mechanism (40), and a motor (20). The casing (10) is configured so as to cover an internal space (70). The internal space (70) includes a first space (71) and a second space (72) larger than the first space (71). The casing (10) has: a first casing section (10a) covering a first space (71); and a second casing section (10b) covering a second space (72). The compression mechanism (40) generates a high-pressure fluid by compressing a low-pressure fluid. The motor (20) drives the compression mechanism (40). Both the first space (71) and the second space (72) are high-pressure spaces configured so as to house high-pressure fluid or, alternatively, the second space (72) is a high-pressure space and the first space (71) is a low-pressure space configured so as to house low-pressure fluid. A metal coating (50A) is formed on at least the outer surface of the first casing section (10a).
