Numerical study of horizontal ground heat exchanger for high energy demand applications

This article proposes a method for designing a horizontal ground heat exchanger for high energy demand applications, as the role of ground heat exchangers on the performance of the ground source heat pumps (GSHP) is very critical. A parametric study is performed to identify the important factors affecting the thermal performance of the ground heat exchanger. A new configuration is proposed which is a combination of horizontal and vertical ground heat exchanger for high energy-demand applications. The figure shows the soil temperature of the centre point between two layers of double layer helical geometry ground heat exchangers over a year that indicates the possibility of using a ground heat exchanger in continuous operation for years.
