A desiccant dehumidifier regenerated by direct absorption of solar radiation was investigated using a simplified numerical model (DESSIM) of the adsorpotion and desorption processes. This paper presents estimates of the performance of an air conditioning system in the ventilation mode using direct solar radiation regeneration. The effects of dehumidifier NTUs, heat exchanger performance, and insolation levels were also analyzed. The direct radiation regeneration system was found to have a COP less than that of other types of regeneration schemes.
