Abstract

An apparatus and method of conditioning humidity and temperature in the process airstream of a desiccant dehumidifier used to dry moisture-laden spaces and structures by replacing moisture-laden air with dehumidified air to increase the rate of water evaporation within the affected areas. A heat-modulating dehumidifier comprises a dehumidification assembly having a desiccant rotor assembly, a post-process pre-reactivation heat exchanger assembly, a reactivation air bypass damper, a reactivation heater, and a control system. The apparatus regulates the temperature level of the dehumidified air exiting the apparatus by extracting heat from the dehumidified air prior to its ejection into an affected area, using a bypass damper that controls the amount of heat transfer from the dehumidified air to a second airstream entering the apparatus.
