Abstract:The carbon dioxide (CO2) is investigated as an alternative refrigerant to replace HFC
(hydro fluorocarbon) refrigerants in refrigerators and air conditioning systems due to the
environmental concerns. Because new compressors with the carbon dioxide are going to be
operated under the high pressure, the tribology of sliding surfaces in the compressor becomes very
important. To develop new compressors, especially rotary type, the friction and wear characteristics
of sliding surfaces between a vane and a roller in… Show more
