Résumé

Due to the awareness of the negative environmental effects caused by the usage of R134a, a new refrigerant R1234yf has been introduced with the intention to replace R134a. This paper looks into the detailed effects on the compressor performance when using R1234yf, as compared to R134a. Firstly, the detailed 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.
