In this research work, the energy efficiency of the introduction of heat pumps into theenergy supply systems of buildings in the conditions of Karshi city was evaluated based on thethermodynamic cycle of the heat pump operating on the basis of a low-temperature source and theexperimental research of its parameters.During the experiments, the energy efficiency of the heat pump was determined at fourtemperatures 5 oC, 10 oC, 15 oC and 20 oC of the low-temperature source. R134a freon, safe forozone, was used as the working fluid.It was observed that the energy conversion coefficient of the heat pump increases with theincrease in the temperature of the low-temperature heat source. During the research, it was foundthat the value of the energy conversion coefficient of the heat pump at different temperatures of thelow-temperature source changed from 2.1 to 3.5. Also, an energy conversion coefficient of 3.5 wasachieved when a heat source with a temperature of 20 oC was used.Based on the results of the conducted experiment, it shows that the use of the heat pump in theheat supply systems is an effective solution, as the value of the energy conversion coefficient of theheat pump is greater than 2 at different temperatures of the low-temperature source in the conditionsof Karshi city.
