Geothermal systems represent a viable alternative to more traditional heating and cooling systems, tapping into the ambient temperature of the earth itself to do its job. When you get down below about five or six feet, the temperature under the ground remains at a constant regardless of what the weather is like upstairs. Geothermal systems run a series of tubes under the earth and then pump some form of refrigerant (usually a mixture of water and antifreeze) through them to facilitate a heat exchange with the ground. Here in Atlanta, geothermal systems have proven quite popular, particularly on property with a lot of square footage. Here’s a quick breakdown of how geothermal systems cool your home.
It starts inside your home, where warm or hot refrigerant is pumped through the central system and into the coils beneath the ground. The temperature under the ground stays set at about 55 degrees or so, which means that the heat from the refrigerant bleeds into the ground as it passes through. By the time it completes its cycle and returns to the house, it’s usually the same temperature as the earth. That, in turn, pulls heat from the air in the in-house portion of the system, cooling it and allowing it to be dispersed through your home with a fan. The process warms the refrigerant up again, just in time to send it back into the coils and start the process anew.
This is very efficient because you’re not expending any energy to warm or cool the refrigerant. The earth is doing that for you, meaning you only need enough power to circulate the liquid and run the fan blowing the cool air into your home. As a result, geothermal systems cost much less to run month-to-month than more traditional forms of air conditioning, saving you a great deal of money in the process.
