In conclusion, R32 is an excellent alternative to replace R410A in terms of performance, but different system components need to be optimized to better fit R32 use. The main design issue of R32 is the high compressor discharge temperature at extreme cooling and heating conditions. Properly sizing the compressor appropriate to R32 properties could be one option. Furthermore, two-phase injection to the compressor at extreme conditions can also be utilized to reduce the compressor discharge temperature.
