The absorbers available and reliable on the market go from 15 kW to more than one megawatt of cooling capacity. For this reason this type of plant are mainly design for high cubage or for industrial processes.
The absorbers are freeze cycles: hot water from 70° to 95° centigrade produced by solar thermal collectors favours the evaporation.
The evaporation and condensation processes of the solution of salts provide cold water at temperature of 7° centigrade, which will be temporary stocked in a cool storage to supply low temperature radiant systems or fan-coil cooling systems.
To obtain chilled water, absorbers need to dissipate the energy that can be used for the production of hot water, for the heating of a swimming pool, or it can be gave up to the air through a drainage system.
This type of plant, coupled with the existing electric chillers, completes the main part of the energetic needs of cooling of the building or of
the process in which it is integrated. The particular feature of these machines is their low-electricity-consumption.
However, the best way to think at solar cooling is as a global system, that satisfies cooling but also heating needs and the production of hot sanitary water or industrial one during winter.
