Description

Ground Source Heat Pump (GSHP) systems have the potential for achieving high system efficiencies. Various types of in-ground heat exchangers have been developed to optimize the performance of using them with heat pump systems for space heating and cooling. This paper evaluates a new Hyperloop Ground Source Heat Pump (HGSHP) system in a numerical way, where a new type of ground heat exchanger, Hyperloop, is used. It consists of multiple capillary tubes buried horizontally and vertically on edge, as a flat mat, in shallow ground. Different types of engineered fill materials, such as sand, etc., can be used to enhance the heat transfer and energy storage in the in-ground region to optimize the efficiency of a heat pump system used in a residential house. The HGSHP system is expected to have higher efficiency compared to a conventional vertical closed-loop GSHP system. The results of numerical simulations in TRNSYS indicate that for a single-family house located in a cold climate (Bismark, North Dakota), the HGSHP system studied can not only meet the heating and cooling loads but also achieve higher efficiency and lower energy consumption (up to 29% energy savings), compared with a conventional vertical GSHP system.
