Experimental evaluation of R22 alternative refrigerants in typical split-system heat pump.
Author(s) : SPATZ M. W., HUGHES H. M., ZHENG J.
Summary
The paper will focus on the experimental evaluation of zero ozone depletion potential alternative refrigerants in a residential split-system heat pump. Tests were conducted on a nominal 10 seasonal energy efficiency ratio, as defined by US standards, 10,500 watt (cooling capacity) heat pump. Refrigerants evaluated included HCFC-22 (as the baseline), an azeotropic mixture, R410A, and a blend, R407C. Necessary modifications (compressor, thermostatic expansion valve, heat exchangers) were made, according to the new refrigerant. Results showed a 3 to 5% improved in efficiency for R410A relative to R22 and generally showed lower efficiency for R407C (typically 4 to 9% lower).
