dc.description.abstractAir-conditioning and heat pumping performance of R32/R152a mixture is measured in the composition range of 20 to 50% R32 with an interval of 10% for the comparison with HCFC22 in a water-source heat pump bench tester. Tests are carried out under the same capacity in the bench tester equipped with a variable speed open type compressor at the evaporation and condensation temperatures of 7/45°C and -7/41°C for summer and winter conditions, respectively. Test results show that the compressor power of R32/R152a mixture is up to 13.7% lower than that of HCFC22 while the coefficient of performance (COP) of R32/R152a mixture is up to 15.8% higher than that of HCFC22. From the view point of energy efficiency, R32/R152a mixture is excellent as compared to HCFC22. Compressor discharge temperatures of R32/R152a mixture are increased up to 15.4°C as compared to those of HCFC22. The amount of charge for R32/R152a mixture is decreased up to 27% as compared to that of HCFC22. Overall, R32/R152a mixture is an excellent long term solution to replace HCFC22 in water-source heat pumps under the similar evaporator and condenser temperatures. The flammability study shows that the mixture is virtually not flammable at the ‘drop-in’ composition of 36%R32/64% R152a.out under the same capacity in the bench tester equipped with a variable speed open type compressor at the evaporation and condensation temperatures of 7/45°C and -7/41°C for summer and winter conditions, respectively.

From the view point of energy efficiency, R32/R152a mixture is excellent as compared to HCFC22.
