Summary

This article presents the description and operation of a simple structure, low cost solar-powered adsorption refrigeration module with the solid adsorption pair of local domestic type charcoal and methanol. The module consists of: a) a modified glass tube with a generator (sorption bed) at one end and a combined evaporator and condenser at the other end and, b) a simple arrangement of plane reflectors to heat the generator. The testing of the module was mainly focused on the sorption bed, therefore, four types (1-4) of bed techniques and four reflector arrangements (A-D) to heat the sorption bed were proposed and tested under the climatic conditions encountered in Cairo (30° latitude). The angles of inclination of the reflectors are varied every month to receive maximum solar energy at noon. A glass shell is used to cover the beds in winter. Test results show that the module composed of the bed technique Type 4 and reflector arrangement Type C gave best performance.
