Abstract

The article describes the experimental setup for testing a heat pump and the results of its operation at various temperatures at its inlet and outlet. An actually task is to study the operation of a heat pump under various boundary conditions, which are determined from the phase transition temperature in the evaporator and condenser. These temperatures depend on the temperature in the evaporator of a low-potential source of heat (the lower source is water, air, etc.) and the temperature in the condenser of a high-potential source of heat (the upper source is a consumer). The main indicator of the efficiency of the heat pump is the coefficient of performance. To determine the reliable value of the coefficient of performance, tests of compression heat pump were carried out. Refrigerant R-142b was used as a working fluid. Based on the experimental data, the dependences of the coefficient of performance on the temperature of the hot and cold heat source are constructed. Also, the coefficient of performance heat pump decreases when the lower heat source decreases.
