Introduction of Water Source Heat Pump System

Living reference work entry


A Ground Source Heat Pump (GSHP) system is a type of energy system that usually consumes electricity to provide cooling and heating in buildings. Its most outstanding feature is the use of ground resources, which distinguishes GSHPs from other heat pump systems. A GSHP may be considered as a “green” system, mainly because of its use of geothermal energy that, as a type of renewable energy, has enormous potential for reducing CO2 emissions and fossil fuel consumption. In general, a higher system performance may be achieved by using a GSHP system compared with an air source heat pump system because of the relatively small temperature variation of the ground compared with the ambient air. In a typical GSHP system there are several main components, including indoor distribution systems and ground source heat exchangers using the ground as a heat sink/source. The role of indoor distribution systems is to handle building cooling and heating loads by absorbing room heat gains or providing heat to rooms through indoor heat pump units. The thermal energy carried by heat pumps is distributed to the ground through ground source heat exchangers buried underground or to the building through pipes/ducts.

In this chapter, in-depth discussions regarding GSHP systems are presented, including the topics of geothermal resources, ground source heat exchangers, indoor distribution systems, heat storage technologies of GSHP systems, and the associated economics and environmental impacts. Additionally, the latest concepts, designs, and technologies for GSHPs are covered.
