Solar Cooling for Cold-Storage Applications Using Solid Desiccants and Adsorbents
Refrigeration plays an important role in the preservation of perishable foods. Many rural areas of the world produce ample food supplies but there are considerable losses due to lack of preservation facilities like refrigeration. In most places where there is no electricity the concept of solar refrigeration seems attractive because of rough coincidence of energy supply and cooling demand. Broadly speaking, solar operated refrigerators are of two types: compression refrigerators powered by photovoltaic cells and absorption refrigerators powered by solar heat. In this paper we discuss possibilities for using solid desiccants and adsorbents in the thermal solar refrigeration systems.
