Experimental results of two drop-in replacement refrigerants for HCFC-22.

Author(s) : JUDGE J. F., HWANG Y., RADERMACHER R.

Summary

Future risk of stratospheric ozone depletion will eventually lead to the phaseout of HCFC-22. To date, no acceptable pure component has been identified as a drop-in substitute for HCFC-22. However, several binary and ternary mixtures of hydrofluorocarbons (HFCs) are currently being promoted by refrigerant manufacturers. The paper investigates the feasibility of three mixtures as replacements for HCFC-22. Two of which are composed of HCFC-32/HFC-125/HFC-134a with the mass compositions 30-10-60% and 23-25-52%. The third mixture is composed of HFC-23/HFC-32/HFC-134a with the mass composition of 4.5-21.5-74.0%. Steady state cooling and heating tests following ASHRAE Standard 116-1983 were carried out for two off-the-shelf air-conditioning/heat pump units with cooling capacities of 2 and 3 tons (7 and 10.5 kilowatts). The results obtained during the tests are presented here and compared to the baseline data measured with HCFC-22.
