This article analyzes the methodology of calculation of the thermodynamic cycle of a vapor compression heat pump installation with a subcooler for heating and hot water supply. As a result of this, the temperature change in the heat pump was analyzed and the process of hot exchange in the device was calculated. As a result of the research, the hotline change coefficient of the device was obtained.
Keywords: Heat Pump, condenser, evaporator temperature, heating coefficient, low-potential heat, regulating valve
