A comparative analysis of refrigerating agents of the heat pump installation of the greenhouse heat supply system did not allow us to identify which of the considered working bodies is the most effective. In this regard, the energy efficiency of refrigerating agents was evaluated using a multicriteria method. The methodology and initial data for calculations are presented. As a result of the research, it was found that the best perfor-mance of a heat pump unit is obtained when using a working fluid from a group of hydro-fluorocarbons.
