The use of refrigeration is increasing day by day for providing thermal comfort in industrial and residential areas. This technology requires energy consumption and is responsible for the emission of CO2 and other greenhouse gases (GHGs), such as chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFCs), which are considered major ozone depleting gases. Adsorption cooling systems are promising for providing a safe alternative to CFC-based refrigeration devices. Solar adsorption refrigerators are a particular type of refrigerator in which compression is avoided and, in a sense, replaced by adsorption. This type of refrigeration is one of the best applications of solar energy because of the greater demand for cooling and for the stronger solar incidence. However, the low coefficient of performance and low specific cooling power, and long cycle time limit the wide–spread application of this kind of system. To improve the performances, some advanced cycles have been proposed and investigated, such as the continuous cycle with double adsorber, which uses a heat recovery process. In this chapter, a heat recovery cycle is studied, based on a numerical model to describe a solar cooling machine. The obtained results demonstrated that the performance of machine using the heat recovery process is better than that without this process. A parametric study is effected and main factors affecting the efficiency of the machine where the performance of the cycle and a heat recovery coefficient are used as a criteria.
