The natural refrigerant CO2 has attracted attention as an alternative to R134a currently used in automotive airconditioning, which has high global warming potential. A scroll compressor was developed for CO2 automotive airconditioning. The pressure of CO2 is much higher than that of R134a, resulting in low CO2 scroll compressor thrust bearing reliability and efficiency because of the large gas thrust. The static pressure assist bearing being developed was confirmed experimentally and analytically to be feasible in CO2 scroll compressor use. Also studied were elastomer, shaft-seal, and refrigerant oil for CO2 refrigerant.
