R407C/R410A: an analysis of the two prominent candidates for the replacement of R22 in refrigeration applications-heat pump systems, energy efficiency, and global warming.

Author(s) : PAULUS-LANCKRIET M., BUYLE O.

Summary

In the context of the phase-out of R22, HFCs are efficient substitutes that optimize the TEWI of installations. These fluids are already used in several existing equipments. Among these alternatives, R410A and R407C are the prominent options. The first one is a nearly azeotropic mixture having a glide of below 0.1 K; on the other hand, R407C is totally zeotropic, with a glide of 7 K. This fundamental difference makes it very important to compare them in applications related to refrigeration, heat pumps and air conditioning. The performances of R407C and R410A have been checked in typical refrigeration conditions. Furthermore, the fractionation of R407C and R410A in the same refrigeration equipment has been measured and compared.
