Glykolkühlung

Glykolkühlung is a type of passive cooling system commonly used in buildings and structures to reduce the temperature inside the building. This system utilizes the principle of heat transfer through mass convection, where a liquid solution of sugar and water is pumped through a network of pipes embedded in the building's structure.

The sugar solution, typically consisting of a 30-40% sugar content, is cooled to a temperature below the room's internal temperature, usually around 5°C to 15°C. As it flows through the pipes, it absorbs heat from the surrounding air, walls, and furniture, bringing the temperature down. The cooled solution then returns to a central server where it is heated up again by a refrigeration unit, allowing it to circulate back to the pipes and continue the cooling process.

The efficiency of Glykolkühlung is influenced by several factors, including the type and concentration of the sugar solution, the pipe density, the flow rate, and the overall system design. Studies have shown that this cooling method can be effective in reducing summer temperatures by as much as 6-8°C, depending on the specific conditions.

Glykolkühlung is environment-friendly and reduces the need for air conditioning and other cooling equipment, resulting in lower operating costs and less energy consumption. It has been implemented in various settings, such as residential buildings, museums, and historic sites, where its dehumidifying effect also helps to prevent damage from mold and humidity.
