Abstract |
The paper gives results of investigations of three hydrofluorocarbon (HFC) refrigerants that have been proposed to replace R-22, which is frequently used as a refrigerant in air-conditioning and heat pump systems. The three replacements are: a ternary mixture of HFC-31/125/234a in the composition of 23/25/52 wt.% (Ternary A, R-407 C) and two binary mixtures, HFC-32/125 in the composition of 50/50 wt.% (Binary A, R-410 A) and HFC-32/125 in the composition of 45/55 wt.% (Binary B). The performance of these refrigerants was investigated in a residential heat pump originally designed for R-22 at the test conditions specified in ASHRAE Standard 116. |
