Comparison of Tribological Characteristics of Vane-piston Interface between R290 and R410A in Rotary Compressor
R290 has been considered for use in air-conditioning systems as a low global warming potential (GWP) refrigerant. This paper describes the tribological characteristic of the vane-piston tribopair in a R290 rotary compressor. For the purpose of simulating the tribopair working conditions, the vanes a...

| description | R290 has been considered for use in air-conditioning systems as a low global warming potential (GWP) refrigerant. This paper describes the tribological characteristic of the vane-piston tribopair in a R290 rotary compressor. For the purpose of simulating the tribopair working conditions, the vanes and rolling pistons of a compressor were directly adopted as test specimens. All of the tribological tests were performed under sealed high-pressure conditions, with test conditions such as the relative sliding speed, loads, and temperatures set based on actual operating conditions of a compressor, and the friction coefficients, scuffing resistances, and wear depths were measured. Furthermore, the morphological changes were investigated using a scanning electron microscope after the tests. As a comparison benchmark, tests were also conducted using R410A/polyolester oil. From these tests, it was evident that the friction coefficients and scuffing load of the vane-piston interface in the presence of R290/mineral oil were respectively 0.05–0.1 and 300 N higher than those of R410A/polyolester. On the other hand, the wear resistance ability with R290/mineral oil was better than that with R410A/polyolester. |
