摘　　要：R32制冷剂与R410A制冷剂的主要物性参数接近,是R410A的热门替代物,但是R32压缩机的排气温度较高,通常采用压缩机吸气带液的方式来降低排气温度。本文研究了不同吸气干度下R32压缩机的排气温度和润滑油粘度的变化趋势,为R32压缩机的开发和应用提供了指导。R32 is a good alternative refrigerant of R410A,since R32 has the similar property of R410A, but the discharge temperature of R32 compressor is higher.Usually the wet suction is used to lower the discharge temperature.We tested the discharge temperature and oil viscosity at different suction vapor quality.The results can provide guidance for design and application of R32 compressor.
