The paper deals with assessment of thermal fields and temperature changesin ground massif with horizontal heat exchanger used as a heat source for a heatpump. Temperatures in the zone of the horizontal ground exchanger are comparedwith temperatures in a reference land. Changes of heat potential of the soil duringthe heating period are also assessed. Possibilities of recovery of thermal potentialof the ground massif when utilizing vertical and horizontal exchangers are analyzedin the opening part of the paper. The results of the first verification indicatedthat average temperatures in the horizontal planes of the ground massif did not differconsiderably with distance from the exchanger tube. Differences in averagetemperatures in reference and experimental lands confirmed sufficient heat potentialof the ground massif even at the peak of the heating period. The differences inaverage temperatures reached up to 6.51 K in the end of the heating period whileat the beginning of the heating period, the differences in average temperaturesdropped to 1.35 K. The differences between maximum and minimum temperaturesin the zone of the ground exchanger reached up to 1.9 K at the peak of the heatingperiod and rose to 3.9 K at the beginning and end of the heating period. The firstresults of our measurements ...
