Solar Refrigeration

Solar refrigeration technologies harness the energy of the sun and use it to run a cooling system. This type of solar application is an attractive option for the preservation of food and the refrigeration of vaccines and medicines in areas with a high intensity of solar radiation and no electricity supply (or only an unreliable supply).

Solar refrigeration first received a great deal of attention a few decades ago during the 1970s oil crisis1. To date, several solar cooling technologies have been developed and some are technically mature, but they are not yet competitive on the global cooling market. The different types of solar cooling appliances that exist today can be divided in two categories: the solar electric and the solar thermal refrigerators2.
