Geothermal systems are specifically designed to take full advantage of all of the energy stored under the ground. There seems to be a lot of confusion in Rincon around about how exactly geothermal systems work. We thought it would be helpful for our customers if we put together a quick explanation. Below are some of the main components in geothermal systems and how they work together.
The Sun and the Earth
As the sun beats down on the earth every day, that energy gets stored in the ground. If you were to dig down about 10 feet into the ground, the temperature there would be about 55° F—and it stays that way all year long. No matter what the temperature of the air is above, the ground is consistently the same temperature. Geothermal systems take advantage of that consistency to heat and cool your home.
The way that geothermal systems are able to harness the energy in the ground is through a series of buried pipes. The pipes can be laid out horizontally if your property has the space for them. They can also be installed vertically in deep holes drilled out of the ground. The pipes are basically one big loop that is connected to a heat pump in your home. The refrigerant enters the heat pump and is then returned out into the ground.
After the pipes are buried in the ground, a refrigerant is pumped through them. This refrigerant is very sensitive to heat and is an environmentally friendly version of other refrigerants like Freon. The refrigerant’s job is to carry heat. A pump is used to move the refrigerant through the pipes.
The Heat Pump
At the heart of a geothermal system is the heat pump. The heat pump is what actually heats and cools your home using an evaporator coil in the air handler. Here’s how it works: in heating mode, the refrigerant will extract heat out of the ground. The heated refrigerant is pumped into the heat pump and through the evaporator coils. A fan blows air over the coils. The newly heated air is then distributed to your home via your ductwork. In cooling mode, the opposite occurs.
