Analysis of Ground Massif Temperatures with Slinky Horizontal Heat Exchanger

The article is describing a ground massif with a Slinky heat exchanger as a heat source for a heat pump, which is used for cold water warming and a heating of an administration building. The object of the research is to analyse the influence of the heat exchanger on the ground massif temperature while extracting heat energy at the beginning and during the heating season 2012 - 2013, as well as beyond it. Based on executed measurements the process of the ground massif temperatures near the exchanger is described. Also described is temperature process of the ground massif on a reference lot in a burial depth of the heat exchanger, and also subsurface temperatures in a depth of 0.2 m. The energy potential of the ground massif was evaluated using the difference of temperatures of the ground massif in the area of the Slinky heat exchanger at the beginning and at the end of the heating season.
