ABSTRACT

To improve the efficiency of using an air heat pump (AHP), it is important to analyze the thermodynamic parameters of the vapor-compression freon loop cycle. To evaluate all thermodynamic processes in the heat recovery system of the air heat pump and to make calculations, experts frequently use heat charts developed by the manufacturers. The authors propose to use tables on saturation line and superheated vapor line of working refrigerant for approximate calculation of vapor-compression freon loop. As a result of calculation of a theoretical vapor -compression cycle, the authors obtained heat energy values taken by the working body during its continuous phase change: boiling, evaporation, condensation, which were determined by the enthalpy state points at the corresponding sections of operation of AHP elements (evaporator, compressor, condenser). Calculations showed that at creating thermal power at the heat pump output, its determining parameter is the phase change of latent heat of vaporization at boiling and condensation of working body in the closed compression cycle system.
