Summary

For the R22 and R407C performance tests the only change made to the heat pump was the installation of electronic expansion valves in place of the factory supplied fixed orifice. R410A required changing the original reciprocal compressor to a smaller displacement scroll compressor (approximately 66% of R22 capacity) to maintain about the same unit cooling capacity as R22. The relative cooling and heating capacities of R407C with the original indoor coil supplied with the heat pump ranged from 0.92 to 1.01. Operating the indoor coil in the inverted configuration improved the cooling capacity, but had a detrimental effect on the heating capacity. Compared to R22, the relative cooling and heating capacity of R410A, with a compressor correction factor applied, ranged from 0.98 to 1.06. The relative energy efficiency ratio (EER) and COP of R410A with a compressor correction factor applied ranged from 1.01. to 1.07 compared to R22.
