Abstract

A method of cooling buildings with solar energy is presented that incorporates a fixed desiccant bed, an evaporative cooler, associated controls and dampers, and conventional components and controls of a solar air heating system. All components are commercially available items and the three heating modes (direct heating with solar, solar heat to storage, and heating from storage) remain unchanged. The three additional operating modes pertaining to cooling (air conditioning, solar regeneration of the desiccant, and night regeneration of the rock bed) have been added. To investigate the thermal performance of the system under typical weather and insolation conditions, a transient simulation model was constructed using TRNSYS. The operating parameters assumed in the model are representative of the building and solar heating system of Solar House II at Colorado State University. The hourly weather values assumed were for a summer season in Washington, D.C. The predicted operating characteristics, thermal coefficient of performance and electrical Energy Efficiency Ratio (EEF) are discussed. (A)
