The issue of using heat pumps for the needs of autonomous heat supply of private houses, office premises and production premises is considered. The analysis of efficiency of work of the compression heat pump with fan coil for heat supply of buildings is given. The current model of the experimental heat pump system developed and constructed in IVE of NASU is presented. The method of conducting research is described. The characteristics of the measuring equipment installed on the experimental setup, which was used to obtain data in the process of research, are given. The results of scientific work obtained in the course of theoretical calculations and experimental studies of the efficiency of the heat pump system are presented. The conversion factor of the air-to-water heat pump in the heating system of a residential building with an area of ​​up to 100 m is calculated. The dependences of the heat pump transformation coefficient on the type of renewable source of low-potential heat energy are given. The dependences of the efficiency of the heat pump system on the parameters of the primary source of low-potential heat and design features of the heat supply system are substantiated. It has been experimentally confirmed and theoretically substantiated that the fan coil is an effective space heating device when working in conjunction with a heat pump. It is substantiated that further studies of heat pump systems implementation are promising, where low-potential energy of natural surface layers of the Earth and water of open reservoirs and aquifers and improvement of heat extraction systems from low-potential renewable energy sources are used as primary sources.
