Summary

Wet compression versus dry compression in heat pumps working with pure refrigerants or non-azeotropic bionary mixtures is investigated in this paper. In total 34 pure refrigerants as well as 31 non-azeotropic binary mixtures at different concentrations are considered. This resulted in approximately 300 different mixtures being analysed. The pure refrigerants were analysed for three different heating applications found in practice: the heating of swimming pool water, heating air for interior space heating, and the heating of water for domestic use. The investigation was conducted with cycle analyses calculating performances at different wet and dry compressor inlet values. Use was made of thermodynamic refrigerant properties calculated from a computer database. A by-product of this study is that from the vast amount of refrigerant mixtures analysed valuable knowledge was gathered regarding refrigerants not commonly used in the application considered.
