Résumé

Due to distillation, lots of designers are concerned by the use of zeotropic refrigerant blends. The main issue comes from the well-known composition difference between the liquid and vapour phases in a zeotropic mixture. In this paper, the impact of such effects was discussed based on experiments performed on a domestic R407C heat pump operating in the heating mode as well as in the cooling mode. The unit has been designed for R407C and experiments have been carried out not only with R407C but also with other mixtures: 33% R32-25% R125-42% R134a and 13% R32-25% R125-62% R134. Thermodynamic analyses (capacity, COP, EER, different compressor efficiencies) confirm globally the theoretical results: degradation of machine performances remains limited, even for such composition variation of mixture. The maximum reduction was registered of COP for the mixture whose mass fraction of R32 is higher.
