Abstract
The energy demand application to thermal comfort is increasing spontaneously in the world. Low-grade energies are promising potential to alleviate fossil fuels use. In the present system, 40% by mass solution of calcium chloride (CaCl2) absorb moist air directly from the process air to reduce the moisture before supply to indoor. This solution is regenerated at a relatively low-temperature heat source by a marquise-shaped channeled flat plate solar collector. The desiccant regeneration is higher for the first one hour and then it is stable. Also, the desiccants solution temperature supplied into the plate heat exchanger (PHE) is also increasing for the first one hour and then almost stable. The relative humidity (RH %) of air leaving the dehumidifier is lower as compared to that of entering.
