Summary

In recent years, there has been much discussion on how to respond to climate change within an international framework. The "Kigali Accord" of the Montreal Protocol, for example, implements phase-down regulations for CFC and HCFC refrigerants from the perspective of global warming and greenhouse gas emission control. In particular, GWP regulations are being discussed in Europe ahead of other countries. For example, if GWP is regulated below 150, HFO refrigerants R1234yf and R454C are candidates as low-GWP refrigerants. HFO mixed refrigerant, which is a mixture of HFC and HFO, is also a candidate, and propane and CO2 are candidates as natural refrigerants. In this paper, we report the effect of R1234yf refrigerant on the performance of a swing and scroll compressor with R32 refrigerant. R1234yf refrigerant has the largest impact on compressor performance due to its low mass density.
