COMPRESSOR PERFORMANCE COMPARISON WHEN USING R134AAND R1234YF AS WORKING FLUIDS

摘要

This paper examines the detailed effects on the compressor performance when using R1234yf as compared to R134a. Firstly, the effects on the compressor performance of the existing compressors which was designed for R134a when using the new refrigerant R1234yf will be presented and discussed. Secondly, the design aspects of a new compressor to be designed for R1234yf will also be presented and discussed. In the paper the rolling piston compressor was used to carry out the simulation tests. The detailed comparison of various performance parameters for the compressor are discussed and shown.
