Geothermal cooling – an energy-efficient solution for summer heat

A ground source heat pump system can be used to cool buildings during the summer. Geothermal cooling is an environmentally friendly way to maintain a comfortable indoor climate, and many of our customers use their Gebwell heat pump system for this purpose during hot weather.

In a geothermal cooling setup, the building is cooled directly with the natural coolness stored underground. Geothermal cooling can be implemented in properties that already use geothermal heating. The most cost-effective time to install the cooling system is during the heat pump installation.

How does geothermal cooling work?

Geothermal cooling is based on a liquid circulating in a borehole, where the temperature remains around 0–8 °C even in summer. This liquid circulates from the ground source heat pump system through a separate, discreet mini-water circuit to a fan convector or ventilation unit. The cool liquid cools the indoor air through the fan. Excess heat is returned to the borehole, improving its efficiency during the heating season. If the system is connected to a ventilation unit, it must be ensured that the duct work is suitable for managing possible condensate.

Efficient and effortless cooling

Geothermal cooling offers an energy-efficient and convenient way to improve indoor comfort during the summer. The cooperation between the heat pump and the cooling system increases overall efficiency, usability, and energy savings.

Gebwell heat pumps are designed for easy integration with a geothermal cooling system. Cooling can also be added later, but it is most convenient to install it alongside the heat pump system.

Read how our customers use geothermal cooling:

• Geothermal cooling is utilized in a semi-detached house in Tampere heated with a Gebwell Aries heat pump.
• Jospak Ltd., a manufacturer of renewable packaging, uses geothermal cooling for both passive and active cooling in its facilities.

Double the savings with geothermal cooling

Geothermal cooling is suitable for large buildings, office spaces, detached houses, and holiday homes. It also benefits wine cellars and food storage areas. Its advantages include a pleasant indoor climate and very low investment and operating costs compared to traditional air conditioning systems.

Because geothermal cooling uses a fluid naturally cooled by the ground, it is nearly cost-free. Only the circulation pump and the fan motor of the indoor unit consume electricity, making the operating costs less than 20 % of those of conventional cooling systems.

Geothermal cooling also increases the value of your investment in a ground source heat pump system.
