Geothermal heat pump is a high efficient and energy saving air conditioning system that provides cooling or heating by using the shallow layer geothermal source(also refers as ground energy source, including soil, groundwater, surface water etc.). The ground source temperature is relatively stable in the whole year, it’s higher than ambient temp. in winter, and lower than ambient temp. in summer, that characteristic makes its energy efficiency is much more than the traditional system. With little premium energy (Electric energy) input, heat pump transfers low temperature thermal energy into high temperature thermal. That is to say, Get the heat from ground and increase its temperature to supply heating to indoor space in winter, and get the heat from indoor space and release it into ground. The ground source heat pump usually gives 5KW cooling or heating capacity by using 1KW electricity.
Comparing with boiler (electricity or fuel) system, heat pump saves 2/3 electricity, or 1/2 fuel energy; as the source temperature is relatively stable, it’s around 10 to 25℃, and it’s cooling, heating coefficient up to 4.8 to 5.5, it’s 40% higher than traditional air source heat pump, and its operation cost is 50% to 60% of the common central air conditioner.
