Abstract: A dehumidification system is disclosed including a regeneration air flow path, a process air flow path, and a recirculation air flow path. In one embodiment, the regeneration air flow path includes a regeneration fan and a refrigeration system having an evaporator coil upstream of a condenser coil. The system also includes a desiccant wheel partially disposed within the process air flow path and partially disposed in the regeneration air flow path downstream of the refrigeration system. The recirculation air flow path is in fluid communication with the regeneration air flow path downstream of the regeneration fan at an inlet and upstream of the refrigeration system at an outlet. The recirculation air flow path is arranged to allow for an air flow to be recirculated through the refrigeration system and the desiccant wheel by the regeneration fan. A heat exchanger may also be provided in the regeneration air flow path.
