Modelling of Heat Transfer in Ground Heat Exchangers

Barbara Larwa, Monika Gwadera, Tadeusz Komorowicz, Krzysztof Kupiec, Mikołaj Teper


The results of the numerical simulation of heat conduction in ground with a horizontal, tubular (parallel pipes) heat exchanger installed are presented in this paper. On the basis of analysis of courses of temperature isolines in the ground, a simplified mathematical heat transfer model in a horizontal ground exchanger was developed. The ground thermal diffusivity was assumed to be a variable of location. On the basis of the model, the temperature profiles in the ground with a heat exchanger installed were determined.
