Abstract: An apparatus and method of conditioning humidity and temperature in the process air stream 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. An air-dehumidifier comprises a dehumidification assembly having a desiccant rotor assembly, a shielded radiant burner assembly, and a control system. The shielded radiant burner assembly is used to regenerate the desiccant rotor by removing moisture from the reactivation quadrant, where high velocity (at least 500 ft/min) air streams are often flowed, by projecting radiant heat onto the rotor, while minimizing the potential for the high velocity air streams interrupting the combustion of air and fuel in the radiant burner.

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.
