Abstract (en)

[origin: EP2565459A1] A rotary compressor contains, as a refrigerant, a single-component refrigerant comprising hydrofluoroolefin having a carbon-carbon double bond or a mixture refrigerant comprising this hydrofluoroolefin and hydrofluorocarbon having no double bond. The rotary compressor includes a compression mechanism 3 having a compression chamber 39 for increasing a pressure of the refrigerant inhaled through the suction port, a discharge port 38 for discharging the refrigerant, the pressure of which has been increased in the compression chamber, and a discharge muffler 37 to cover the discharge port. A spatial volume of the discharge muffler is determined depending on a density of the refrigerant, thereby making it possible to provide a rotary compressor capable of positively reducing a pressure loss associated with an increase in flow rate of the refrigerant, preventing a rise in discharge temperature, and restraining a reduction in reliability or durability that may be caused by decomposition of the refrigerant.
