The regeneration of silica gel desiccant by a solar air heater for use in an air-conditioning system has been investigated. The hot air is produced by a compound parabolic concentrator collector (CPC), which has aperture and receiver areas 1.44 and 0.48m2, respectively. The regeneration...

A theoretical model of an intermittent solar powered charcoal/methanol refrigerator has been developed to study its performance. The model is used to investigate the heat and mass transfer in a tubular flat-plate collector (adsorber), which is heated by the sun and which contains activated...

A method for measuring the performance parameters of a solar thermal collector under non-steady conditions has been applied to an air heater with a truncated compound parabolic concentrator having an aperture area of 1.44m2 and a flat absorber with concentration ratio three. This type of...

The adsorptive properties of several activated charcoal/methanol combinations were measured in the laboratory. The Dubinin-Astakhov equation is used to analyze the data, and pressure-temperature-concentration diagrams are given. From these results the coefficients of performance of ideal...
