Abstract: As the alternative of R410A, the amount of R32 compressor will up to 50% of the AC market. The operation presser is similar between R32 and R410A, but the thermal properties are not. As a key component of an air conditioner, R32 compressor needs to be designed according to R32 thermal properties. In this paper, a mathematical model of R32 compressor was built to optimize the main structure parameters, and the leakage, heat transfer and friction of a R32 compressor were discussed. Finally the performance of developed R32 compressor in this paper has been increased by 3% compared with the original R32 compressor.

Key words: R32, Compressor, Performance
