There is more to solar thermal units than hot water generation and heating purposes. When combined with adsorption chiller systems the excess heat energy serves as a source to generate environmentally friendly and efficient cold for the solar cooling of buildings and processes. The pay-off is especially attractive during the summer, when the demand for air-conditioning is high and the sun generates heat in abundance.

Thanks to adsorption refrigeration technology the components of a solar unit (storage and collectors) can now be better utilized and protected from overheating and overload. In turn, this extends the lifespan of the system and increases its economic efficiency.

Another benefit of adsorption chiller technology is the very low supply temperature a solar system would have to deliver to sustain the cooling process and to maximize the usage of the solar heat.

Last but not least: this intelligent technology can function as a heat pump during the winter heating period. With this alternative option even low solar collector temperatures can generate additional usable thermal heat.
