An overview of ground-source heat pump technology

Abstract

Ground-source heat pumps (GSHPs) are renewable and environment-friendly systems that utilize the shallow ground energy to achieve space heating and cooling for the purpose of thermal comfort. The system works by circulating water-based solution in energy loops made from high-density polyethylene (HDPE) pipes, to transfer heat energy between superstructures (buildings) and the ground. This chapter presents an overview of the GSHP technology including different components of the system and their respective working principle, design considerations, and factors affecting the system performance. Lastly, few case studies are presented to give the reader an insight into GSHP systems currently operating in the UK.
