Summary

Measurements show an almost identical COP for R407C and for the R125-R134a-R600 (46-50-4) mixture with values approximately 6% lower for these 2 refrigerants compared with R22. Nevertheless, it is clear that this mixture, under each of the 3 conditions, is based on the evaluation of refrigerant capacity, on one hand, and on the need to reuse the mineral oil, on the other hand.
