ABSTRACT:
A compact apparatus for dehumidification and cooling of air for use in air conditioning of buildings comprises a container with stationary matrices, air fans, water pumps and a solid state processor, with the stationary matrices providing a periodic flow type energy efficient transfer of heat, dehumidification and evaporative cooling of air. Dehumidification of air and reactivation of the spent desiccant is achieved by the energy of the outdoor air and results in a cooling energy efficiency ratio of the apparatus (EER) 10 to 20 times larger than that of the most energy efficient vapor compression systems. Only a small amount of electric power is used to operate air fans providing alternate, periodic and countercurrent flow of the primary and the secondary air streams through the apparatus, and to operate water pumps used in evaporative cooling of the air. Operation of the apparatus is automatic and is controlled by a solid state processor. The apparatus intended for use in air conditioning and ventilation of buildings can be easily adapted for use in numerous industrial dehumidifying and cooling operations.
