Effects of lubricant on carbon dioxide heat transfer in transcritical refrigerating cycles.

Author(s) : ZILIO C., MANCIN S.

Summary

The working fluid in refrigerating or heat pump units consists of a zeotropic mixture including the refrigerant (pure or mixture) and a blend of several molecules constituting the lubricant (oil). The analysis of the actual behaviour of the mentioned oil + refrigerant mixture inside each circuit component is rather complicated, since the presence of the lubricant strongly affects the thermophysical properties of the flowing fluid and thus plays a key role in the heat transfer process. The impact of lubricant on both gas-cooling and evaporation processes is reported in this paper, with reference to research work appeared in the open literature.
