ABSTRACT:
A desiccant assisted system for dehumidification and cooling of an enclosed space comprising a rotatable desiccant wheel and a rotatable heat exchange wheel. A first path for process air extends from an exit of the enclosed space to be conditioned in series through a first zone of the rotatable desiccant wheel, a first zone of the rotatable heat exchange wheel and an entrance to the enclosed space. A second path for regenerative air extends from an entrance to ambient air outside the enclosed space in series through a second zone of the rotatable heat exchange wheel, a second zone of the rotatable desiccant wheel and an exit back to ambient air outside the enclosed space. Condenser coil(s) are provided along the second, regeneration air path between the rotatable wheels. A compressor is provided and a first process evaporator is coupled with the compressor and located along the first path. A second process evaporator located in series along the first path between the first process evaporator and the entrance to the enclosed space. A condenser is coupled with the compressor and located along the second path between the rotatable wheels. A recovery evaporator is also coupled with the compressor and located in series along the second path.
