Abstract
An air conditioning system that can be driven by solar energy. A solar collector used energy from the sun to evaporate water from a desiccant fluid. The desiccant fluid is then flows into a mass transfer device which removes moisture from an air stream. Calcium chloride is the preferred desiccant material and can serve as an energy-storage medium. Electric or fuel backup can be used with this system to regenerate the desiccant material. In some embodiments an indirect evaporative cooler is added to provide sensible cooling. A new desiccant cooling system that is specially designed to work with the properties of this desiccant and meet comfort requirements of conventional air conditioning.
