Although the study was carried out in 1991 and the number of experts that answered all the questions were
only 16, the methodology employed and the type of results obtained gave a clear view of the potential of
solar refrigeration technology and what is needed to do in terms of cost and efficiency.
It should be mentioned that desiccant cooling systems were not included in this study and that the experts
consulted provided no information.
In the basis of the aforementioned study, in this paper a recent review was carried out in order to identify
the type of solar cooling and refrigeration technologies that are being development in the world in the last
years.
There is has not been a large amount of work published recently on solar cooling systems.
