Summary

In the paper, the performance of three high pressure HFC refrigerants: R32, R410A, and R410B, is compared to that of R22. R32 has excellent thermophysical properties as compared to R410A, R410B and R22. However, R32 is a flammable refrigerant while R410A and R410B are non-flammable. The performance of these refrigerants is investigated in a residential heat pump. R32 has a cooling seasonal performance that is 5.1% better than R22 and a heating seasonal performance that is 2.5-4% better than R22. R410A and R410B have cooling seasonal performances which are 2-3% better than R22, and heating seasonal performances that are similar to that of R22.
