Summary

In commercial refrigeration, high GWP refrigerants such as R134a and R404A are huge contributors of release of HFC’s to the environment. Because of increasing concerns about climate change, various environmental regulations have been proposed to phase out these refrigerants. The transition to new age environmentally friendly low GWP refrigerants R471A, requires an understanding of refrigerant/lubricant properties and material compatibility with refrigerants. In this paper, the solubility and miscibility of R471A with polyol ester-based oil (POE32) is experimentally investigated at over a temperature range of -30°C to 110°C. Further this paper also presents the compatibility results of new refrigerants and common materials used in refrigeration and air-conditioning systems.
