摘要： A scroll compressor employs therein a refrigerant having a small global warming potential and a small ozone depletion potential and mainly comprising hydrofluoroolefin having a carbon-carbon double bond. A stationary scroll has and end plate and a discharge port defined in the end plate at a central portion thereof so as to open into a discharge chamber. The stationary scroll also has a bypass hole defined in the end plate to allow a plurality of compression chambers to communicate with the discharge chamber before the compression chambers communicate with the discharge port. A check valve is provided on the bypass hole to allow the refrigerant to flow from the compression chambers to the discharge chamber. This construction can restrain a baneful influence on the global environment, reduce a temperature increase caused by excessive compression, and restrain decomposition of the refrigerant even in long-term use.

摘要： A refrigerant being low in both ODP and GWP and containing at least hydrofluoroolefin having a double bond of carbon is used. By providing a first compression-chamber oil feed path for feeding refrigerating machine oil to a compression chamber 15 after the refrigerant has been enclosed therein, effects on the global environment can be suppressed and moreover temperature increases of the refrigerant due to re-expansion heating and feeding of high-temperature refrigerating machine oil can be suppressed, i.e., decomposition of the refrigerant can be inhibited.

摘要： In a compressor, a single refrigerant of hydrofluoroolefin having a double bond of carbon or a mixed refrigerant containing hydrofluoroolefin and hydrofluorocarbon having no double bond of carbon is used, and moreover a refrigerating machine oil containing an additive for suppressing deterioration of the refrigerating machine oil and an antiwear agent is used, the compressor including a sliding portion which is exposed to the mixed refrigerant and the refrigerating machine oil and which has a hardness of 47-55 HRC. Thus, decomposition and polymerization of the refrigerant and the refrigerating machine oil can be inhibited (i.e., occurrence of sludge can be inhibited), and antiwear property of sliding portions, e.g. vane and piston, of the compressor can be maintained. As a result, reliability of the compressor and the refrigerating cycle apparatus using the compressor can be ensured.
