Description Unlike conventional HVAC systems, sorptionUnlike conventional HVAC systems, sorption cooling systems do not require an external cooling source for cooling and dehumidification of the air. Conventional HVAC systems are systems that supply mechanical energy (compression cooling) whereas sorption cooling machines use heat as energy source. The efficiency of both systems is comparable. Traditionally, the technology is used in the process industry (e.g. in breweries or for food production) to ensure the refrigeration supply in the production. Five main components are necessary to run a sorption cooling system. Condensor, evaporator, expeller (also named reactor or generator), absorber and pump. Depending on the mode of binding the water vapor – there is a distinction between absorption (continuous cooling is possible) and adsorption (nearly continuous cooling possible). In both cases the air is dehumidified and cooled by the release of latent heat. The technology is available with solid (adsorption cooling) and fluid (absorption cooling) absorbers. Both are hygroscopic materials. The water vapor contained in the air is removed from the air stream due to the difference in the partial pressure. In parallel the temperature of the air and thereby the room temperature is reduced.d thereby the room temperature is reduced.  +
