Abstract (en)
[origin: EP2578887A1] A single-component refrigerant mainly comprising hydrofluoroolefin having a carbon-carbon double bond or a mixture refrigerant including this refrigerant is used as a refrigerant. An axial length L of a discharge port 14 is set to be less than a thickness H of a member in which the discharge port 14 is formed, thereby making it possible to reduce a length of the discharge port in a direction of a flow passage to reduce a pressure loss and restrain an unnecessary pressure increase in a compression mechanism 4 to reduce a temperature increase of the refrigerant. At the same time, because a volume of the discharge port 14 filled with a high-pressure gas refrigerant can be made smaller, the high-pressure gas refrigerant remaining in the discharge port 14 after completion of a discharge process in the compression mechanism 4 is restrained from flowing back toward a low-pressure side compression chamber 9. Accordingly, a temperature increase of the refrigerant caused by re-expansion and re-compression can be also restrained.
