GEOTHERMAL HEAT PUMP SYSTEMS

A geothermal heat pump (ground source heat pump) is a central heating and/or cooling system which transfers heat to or from the ground. Earth is used as a heat source (in the winter) and a heat sink (in the summer). The shallow ground temperature is more stable than the ambient air. This design takes advantage of the moderate temperatures in the ground to boost efficiency and reduce the operational costs of heating and cooling systems, and may be combined with solar heating to form a geosolar system with even greater efficiency. There is no effect of Geothermal energy on ecology and it won't cause environmental pollution. CO2 emission is also being reduced to high extend. Coefficient of performance (COP) of GSHP system is high i.e. 3 to 6. Installation costs are higher than for conventional systems, but the return on investment (ROI) is less i.e. from 3 to 10 years. The ground source heat pumps are the most energy-efficient, environmentally clean, and cost-effective space conditioning systems. GSHP systems have larger lifespan than that of conventional heating and cooling systems. The geothermal heat pump can be installed in small residential and office buildings, shopping malls and stores etc. In coming years, geothermal heat pump will play an important role in reducing emission of CO2, global warming and saving conventional energy sources.
