Title:
ROTARY COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2011/135817
Kind Code:
A1
Abstract:
Disclosed is a rotary compressor provided with a compression chamber (39) wherein a single refrigerant of hydrofluoroolefin having double bonds between carbons, or a working refrigerant which at least essentially contains the hydrofluoroolefin mixed with hydrofluorocarbon having no double bonds, is enclosed, and a compression mechanism unit (3) suctions the working refrigerant, and increases the pressure of the working refrigerant; a discharge port (38) for discharging the working refrigerant compressed in the compression chamber; and a discharge valve (36) having a tip portion which covers the discharge port. The entire sectional area of the opening of the discharge port is set in accordance with the density of the working refrigerant. Thus, pressure loss can be reliably reduced, a high efficiency can be obtained, and the reliability and durability can be improved.
