ABSTRACT:
An apparatus for dehumidification and cooling of moist air for use in ventilation and air - conditioning applications comprises two fixed bed sorption dehumidification-heat recovery units equipped with a valving system permitting continuous countercurrent cyclic operation removing moisture and sorption heat from the treated moist outdoor air to provide dehumidified and cool fresh air. Additional cooling of the treated fresh air if desired may be achieved in a conventional direct evaporative cooler. Released sorption heat is recovered and used in reactivation of the spent sorbent material with the required additional heat being provided by fossil fuel, solar or waste heat energy sources. Small amount of electric power is used for operation of two air blowers that provide also balanced ventilation of the air conditioned space. Cooling COP of the apparatus is higher than that of the prior art systems.
