Thermodynamic efficiency of heat pump systems
UDC 621.577
Suhih A. A., Antanenkova I. S.
Abstract
Presented here are the results of the analysis on the efficiency of using a wide range of substances as working media in heat pump systems. The analysis was based on the techniques developed by the authors who suggested equal temperature pressures between a heat transfer agent and working medium in the evaporator and condenser with fixed parameters of heat transfer agents in heat exchangers. Besides, prerequisites and criteria have been formulated and analyzed for regenerative cycles used in such systems with the purpose of increasing their thermodynamic efficiency. The set of substances best suited for this purpose has been identified.
Keywords: thermodynamic efficiency, heat pump systems, refrigerants, working media, regeneration, fluorocarbons.
