The relationships refer to instantaneous and continuous as well as point and ring heat sources which are discussed. The relationship relating to continuous ring source is the basis for modelling and designing of spiral ground heat exchangers. Heat transfer in the infinite and semi-infinite body was considered. In the latter case, the image method was discussed. Using the results of measurements regarding heat transfer in the ground with a heat exchanger in the form of a single coil installed, a comparison of calculated ground temperatures with measured values was presented.}, type={Article}, title={Principles of modelling of slinky-coil ground heat exchangers}, URL={http://czasopisma.pan.pl/Content/113708/PDF/art01.pdf}, doi={10.24425/cpe.2019.130225}, keywords={slinky-coil ground heat exchangers, analytical model of heat transfer}, }
