R32, is increasingly gaining favour as a low temperature refrigerant and as a replacement gas in some R410A applications. R32 has a low GWP, providing a lower carbon footprint than most other HFCs.
R32 has a better system efficiency, and it needs a smaller refrigerant charge. The significant problem is that R32 has a high discharge temperature. Its direct consequence is the oil degradation which can cause various compressor failures like bearing seizure, low system and compressor efficiency. So the discharge temperature should be limited at an acceptable level to make sure that system and compressor could work normally. Usually is to control discharge temperature by refrigerant.
