Solarthermische Gebäudeklimatisierung in trocken-heissen Regionen

Global warming and rising societal demands are increasingly leading to air-conditioned buildings worldwide. Conventional air conditioning systems are powered by electrical energy, resulting in a significant increase in electricity consumption. Since about two-thirds of the world's electrical energy is generated from the combustion of fossil fuels, this leads to a sharp rise in carbon dioxide emissions. Increasing emissions exacerbate global warming and heighten the use of air conditioning. A harmful cycle is created, pushing the global goal of reducing carbon dioxide emissions further out of reach.

The solar air conditioning systems that have so far been available as the only alternative to electrically powered air conditioners generally have a high water consumption or cannot be used at all in arid-hot regions, where air conditioning is most urgently needed, due to the necessary water-consuming system cooling.

Bernhard Lenz has developed a novel air conditioning system specifically for dry-hot regions, based on the use of thermal solar energy, which operates without carbon dioxide emissions and is also primary energy neutral and water-free—thus suitable for breaking the harmful cycle of increasing carbon dioxide emissions.

In this study, Lenz presents his patented system in detail and explains its functionality. The book can also serve as a valuable planning aid for the implementation of such an air conditioning system.
