Varmekjøling

Varmekjøling, a term originating from Norwegian, translates directly to "heat cooling" or "warm cooling". It refers to a specific type of passive cooling system that utilizes the natural temperature difference between the earth and the air to regulate indoor temperatures. This method is often implemented in buildings, particularly in warmer climates, to reduce reliance on active air conditioning systems.

The fundamental principle behind varmekjøling involves directing warmer air from inside a building into a subterranean loop. As the air passes through these underground pipes or channels, it is cooled by the relatively stable and cooler temperature of the earth. Once cooled, this air is then recirculated back into the building, thereby lowering the overall indoor temperature. The effectiveness of this system is dependent on factors such as the depth of the underground installation, the length of the pipes, and the thermal properties of the surrounding soil.

Varmekjøling offers several advantages, including energy savings and a reduced carbon footprint due to its minimal electricity consumption compared to conventional cooling methods. It can also contribute to improved indoor air quality by pre-filtering the air before it enters the building. While its initial installation can involve a higher upfront cost, the long-term operational savings and environmental benefits make it an attractive sustainable building solution. The concept is a practical application of geothermal principles for thermal comfort.
