The cooling and heating of spaces are among the largest sources for householdâ??s\nenergy demand. Ground Source Heat Pump (GSHP) is a promising\ntechnology to reduce the energy for cooling and heating purposes. However,\nthe major obstacle hindering the utilization of this technology is the high initial\ncost, especially for the installation of ground coupled heat exchanger. The\nhorizontal closed-loop system offers lower installation cost, as it requires no\nvertical borehole construction. Instead, the heat exchangers can be installed\nin shallow trenches that may be excavated, by small excavator or even by human\nlabor. This paper presents the comparison of two different heat exchangers,\nnamely, the capillary mat and the widely used slinky pipe. Both heat exchangers\nare connected to a heat pump, where continuous heating tests were\ncarried out for 165 hours (APPROX..7 days) for each configuration. The purpose of\nthis research is to show the performance of capillary mat in comparison to\nslinky pipe. Despite during the entire test for capillary mat required 6% higher\nelectricity consumption, compared to slinky heat exchanger, the results still\nsuggest the potential use of capillary mat as alternative to slinky heat exchanger.\nAdditionally, the results also highlight the high hydraulic resistance\nof installed capillary mat heat exchangers may become the major disadvantage\nof the capillary mat.
