How Geothermal Cooling Works

If you dig a 10-foot hole in the ground and go down inside it, you’ll find that no matter how hot or cold it is on the surface, the temperature in the ground will feel the same. What you are feeling is the heat coming from the core of the Earth; regardless of the temperature on the surface—whether a blazing 95°F or frigid 10°F—the area underground will remain around 55°F.

This temperature stability is the secret behind geothermal cooling through the use of a geothermal heat pump. These comfort systems can bring reliable heating and cooling to a home that is both environmentally friendly and energy-saving.

The Operation of Geothermal Cooling

Since people usually connect the word “geothermal” with “heat” (not much of a surprise since the word contains the root “-thermal”), they rarely make the connection with cooling. But geothermal energy works exceptionally well for providing air conditioning.

A geothermal system works as a type of heat pump. Instead of using the air as its medium for heat exchange (drawing heat from the outside air in heating mode, depositing heat in the outside air in cooling mode), it uses the earth down at a stable temperature level. Plastic loops buried in the ground carry water with antifreeze as a refrigerant, and this water either absorbs or releases heat, depending on the mode the heat pump is in.

During a hot summer in North Carolina, a geothermal heat pump absorbs heat from inside a home along with an evaporator coil, just as a standard air conditioner does. It then moves that heat to the cool temperature in the earth and deposits it there. This works more efficiently than trying to release that same heat into the already hot outside air.

Geothermal heat pumps will help you save money on utility bills both in summer and in winter. And, unlike standard heat pumps, a geothermal heat pump will never struggle in weather extremes thanks to the Earth’s reliably constant temperature.

Geothermal systems can work in many places; thanks to vertical loop configurations, they can even run effectively in locations with limited ground space.
