Leakage Research of Split-type Air-conditioner using R290 as Refrigerant

Zhileng xuebao, 2013
The ozone depletion potential (ODP) and global warming potential (GWP) of HCFCs and HFCs are higher than hydrocarbons (HCs). R290 is perfect in environmental protection and energy saving performance.

Comparison of Tribological Characteristics of Vane-piston Interface between R290 and R410A in Rotary Compressor

Zhileng xuebao, 2018
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
