A solar powered desiccant cooling system using two fixed bed silica gel dehumidifiers has been designed, built and is being tested. The dehumidifiers, 0.6 x 0.6 x 0.6 m each, are constructed of 80 channels lined with 64 m/sup 2/ of 1.5 mm thick silica gel sheets. The bed is cooled by air flowing in an equal number of perpendicular channels. Both sets of channels are two mm wide, the dehumidifiers undergo adsorption, preheating, desorption and precooling in a cyclic fashion. The cooling capacity of the experimental system is one ton at ARI design conditions. The system has a high cooling capacity, high COP, low parasitic power consumption and requires low regeneration temperatures.
