How do Geothermal heating and cooling systems work?
Geothermal systems use technology known as ground source heat pumps to make the transfer of hot and cool air more efficient. A Geothermal Ground Source Heat Pump is the single most efficient way to heat and cool a space such as a home or office. A Geothermal system removes heat from the space and rejects it into the ground during the cooling periods and then pulls heat out of the ground and puts it back into the space during the heating periods.
Geothermal systems are extremely efficient because they are able to work with a consistent ground temperature as opposed to a conventional air source heat pump, or air conditioner that is trying to work against outside temperatures that often vary greatly from the desired comfort level inside.
The simple explanation is this: During the cooling period, heat is absorbed into the refrigerant. That heat is then transferred from the refrigerant through a heat exchanger into the water. The water is then pumped through a series of pipes through the ground using a loop water circulator pump and the heat is absorbed into the ground. After the ground absorbs heat from the water, the cooler water is returned to the house ready to absorb more heat.
