HORIZONTAL GROUND HEAT EXCHANGERS - LOW-TEMPERATURE ENERGY SOURCE

Popis výsledku v původním jazyce

The aim of this paper is to analyse and compare the temperatures of heat carrier fluids, thermal resistances, specific outputs and extracted energies for horizontal ground heat exchangers used in the function of low-temperature energy source for heat pumps. Linear and Slinky type horizontal ground heat exchangers, the most commonly used ones in Europe, were verified. The temperatures of the heat carrier fluids did not reach negative temperatures in the two horizontal exchangers throughout the monitored period. The results of the verification indicated that, in terms of the monitored parameters, the linear horizontal exchanger seemed to be more effective than the Slinky type. The temperatures of the heat carrier fluid were on average higher at the linear exchanger by 1,43 +/- 2,12 K, with a specific output of 5,76 W per 1 m(2) of the heat exchange surface. The thermal resistance was higher at the Slinky than at the linear exchanger by 50%
