| Abstract: | The models described in this article simulate the solid-adsorption cycles of a solar refrigerator. They are used for calculating the performances of the refrigerator as a function of the climatic conditions, and thus optimizing its operation and sizing. The results show that for the same season the performances of the refrigerator are different for the climates of Rabat and Marrakesh. The study of the cold storage shows that, although the annual mean cold production is similar for both sites, the distribution of cooling-shortage days is totally different. In contrast with Rabat, where the problem of cold storage is due to sequences of successive days with low incident solar energy, the problem in Marrakesh is due to high values of ambient temperature during quite a long period of the year, which reduce significantly the refrigerator performances. |
