In order to further increase the energy efficiency of the experimental building, field experiments were conducted to maintain the proper thermal regime of its premises when using a heat pump heating system. The paper presents the results of experimental studies of the operating parameters of the heat pump heat supply system of an energy-efficient building of the Institute of Engineering Thermophysics of the National Academy of Sciences of Ukraine. The given analysis of the energy efficiency of the operation of the "soil-water" type heat pump in the nominal mode with the maximum load showed a high value of the energy conversion coefficient.

The description of original technical decision of using heat pump for heating part of administrating building is described. The hydraulic connection scheme has been developed and selection of heat devices was made for it. The energy efficiency for using heat pump in heating season is analyzed. Based on the obtained experimental data, the coefficient of performance of the heat pump was calculated for the above mode of operation of the heat supply system. With such indicators, a significant saving of thermal energy is achieved in comparison with the use of a centralized heat supply system.
