What is Solar Cooling?
Solar cooling is based on the idea
to combine solar thermal collectors
with a system which is able to
change solar energy into cold.
The solar thermal driven cooling technologies ca
be divided into three principle technologies:
absorption, adsorption chillers, and open
sorption assisted air conditioning systems
(DEC). Most solar cooling systems use absorption
chillers (60% in Europe, Source: IEA SHC Task
38, Solar Air-conditioning and Refrigeration).
In principle these work like normal electrically
driven, compressor refrigerators. Instead of
electricity the absorption chiller in a solar
cooling system uses hot water from solar thermal
collectors to generate cold , e.g. for the
cooling of a room a whole building.

The chillers provide cold water at temperatures
between 6 degrees Celsius and 18 degrees
Celsius. They can therefore be used for central
air conditioners as well as cooling systems with
decentralised air treatment, such as fan coils
and cooing ceilings. Additionally the heat
source of the solar thermal collectors, could be
used for hot water during the year (swimming
pool, kitchen, shower, etc.) and for the heating
system in winter time.
Harness the plenty hours of sunlight
that bless our Islands, and reap its
many benefits in your everyday
needs. |
