摘要：
The results of experimental studies of the heating system performance of a building located in the area of temperate continental climate with temperatures in the heating period down to -30 degrees C are discussed. The studied heating system comprises an air-liquid heat pump, a liquid-liquid heat pump with a ground circuit, and an electric boiler for peak demands. The paper presents the results of the influence of the ground thermal potential recovery system on the liquid-liquid heat pump performance. Also the influence of the used method of heat load prediction on the system efficiency and indoor air temperature stability is shown. Implementation of the thermal potential recovery system allows to increase the average value of the transformation coefficient for the liquid-liquid heat pump from 2.7 to 2.9 during three years of operation. Heat load prediction leads to stable indoor air temperature in the range of 22 +/- 1 degrees C. Also it allows to level out the dependence of indoor temperature fluctuations on outdoor air temperature fluctuations.
