Ground mass temperature analysis with the slinky type horizontal ground heat exchanger.

Summary

This article deals with the specification of ground mass temperatures and the analysis of their changes in the area of the Slinky type horizontal heat exchanger during the heating season as well as during the stagnation period of the heat exchanger. The heat exchanger consists of polyethylene piping 32 x 2.9 mm, resistant to point load and the occurrence of cracks. Heat exchanger piping with the total length of 200 m is installed at a depth of 1.5 m. Ground mass temperatures were measured in the area of the heat exchanger and at a depth of 0.2 m below the ground mass level. Parametric equations of changes in ground mass temperatures in the individual operation phases of the heat exchanger are determined herein. The energy potential of the ground mass is assessed by the ground mass temperature difference in the area of the heat exchanger at the beginning and end of the heating season. The specific heat output of the ground heat exchanger is determined and the impacts of the coefficient of heat transfer between the inner wall of heat exchanger tube and the heat transfer fluid on the heat output supplied by the ground mass are analysed. The verification results show that the Slinky type horizontal ground heat exchangers may be deemed to be stable sources of energy for heat pumps.
