How it Works.

. Over the winter the refrigerant absorbs heat from the. Geothermal heat pumps GHPs sometimes referred to as GeoExchange earth-coupled ground-source or water-source heat pumps have been in use. The DOE has a thorough discussion of geothermal heat pump technology.

The ground temperatures range from 7 to 21 degrees. The following image shows how the heat pump relies on a refrigerant cycle to deliver or extract heat from a building. Geothermal heat pumps work by tapping into the renewable solar energy stored in the ground to provide savings of up to 72 on heating and cooling costs.

The geothermal heat pump absorbs heat from indoor air and transmits it to a ground heat exchanger. According to the International Ground Source Heat Pump Association the choice of ground source heat pump systems provides savings in energy. A geothermal heat pump is a kind of central heating or cooling system that is able to transfer heat directly to and from the ground.

Geothermal heat pumps are also called ground-source heat pumps which use underground heat by pumping water through the ground. The heat is dumped into the earth through the heat exchanger. They are the air handling system the heat exchanger and a reversible refrigerant loop.

There are many different types of geothermal. There are three main parts to a geothermal heat pump system. The benefits of geothermal heat pumps.
