The lubricant, which is considered as the necessary part inside the compressor, not only affects the operating efficiency of the compressor but also has interaction with refrigerant. To study the effect of lubricants on the improvement of heat pump performance, this paper investigated the types and the viscosities of lubricants that are chosen to apply in the heat pump cycle. The influence of lubricants was explained from three aspects: the interaction with refrigerants, the effect on the compressor, and the impact on the system performance, which may make some contribution to the development of new lubricant oils.
