How Geothermal Cooling Works

If you’re investing in air conditioning, you may want to consider a geothermal heat pump for your geothermal cooling needs.

When people hear the word “geothermal,” they might think of how the heat from the earth is used to offer warmth. It’s not crazy for people to think this since that’s exactly what a word like geothermal would suggest. Geothermal pumps are also a wonderful way to give warmth to your home.

However, geothermal heat pumps, like any other heat pump, provides cooling too. Seeing as how we’re at the start of summer, this may be an ideal time to set up the air conditioning. If you’re investing in air conditioning, you may want to consider a geothermal heat pump for your geothermal cooling needs.

How Do Geothermal Heat Pumps Offer Cooling?

The interior of the heat pump is similar to an air-source heat pump. It has a refrigerant coil that condenses or vaporizes the refrigerant, and a blower fan sends the air inside of the ventilation system. Air-source heat pumps have outdoor coils that run the heat exchange. However, a geothermal heat pump has loops that are safely contained underground.

The coils go as deep as ten feet beneath the earth’s surface, which makes it easier to maintain a stable temperature. Now we start the geothermal cooling process. Any time the heat pump switches to cooling mode, the refrigerant absorbs inside heat and transfers it to a water/anti-freeze mixture going through the coils. The heat gets stored underground, away from the house. This is how geothermal cooling works, by removing the heat from the house and storing that heat in the earth. Geothermal cooling can be reversed when the pump is in heating mode. This brings the underground heat back into the house.

Benefits Of Geothermal Cooling

So what are the perks to owning a geothermal heat pump? Why pick geothermal cooling over other options? Considering how big a task it is to install the ground loops, you want to be sure it’s worth your while.

Fortunately, there are advantages to geothermal cooling. Geothermal heat pumps are much more energy efficient and are incredibly reliable. The U.S. Department of Energy has stated that geothermal heat pumps work between three and six times more efficiently than air pumps. So while you pay noticeable costs up front, you will quickly make up the difference in the energy that you save. Since the earth has a fairly stable temperature, the heat pump has an enormous heating/cooling source, making it very dependable. As a bonus, geothermal systems are environmentally-friendly.
