Recently, the cooling market has witnessed a significant growth resulting in a considerable
increase in the demand for electricity. Demand peaks during the hottest days and has
become a serious problem in terms of power network stability. This can be seen during
summer in Poland, where electricity demand over those few days, is greater than compared
to winter. In general, the summer peak in electrical demand due to space cooling installations
is a common problem in European countries. Fortunately, the high availability of solar
energy is correlated with the cooling demands of buildings. A condition that creates
an opportunity for the application of solar cooling systems. Thus, solar energy may reduce
the consumption of power produced from conventional energy sources and at the same time
reduce the peak of electrical energy demand. The available solar thermal collectors with
sufficient and insufficient temperature output to drive the solar cooling process are presented.
In the case of insufficient temperature output, auxiliary units have been considered.
The absorption technology has been reviewed. Some simulation and experimental results of
systems presented in literature are discussed in the paper. Finally, an example simulation of
a hybrid solar system of heat generation, including flat plate collectors, a solar concentrator
and an absorption chiller, is presented.
