Abstract: A reverse flow dehumidifier system for dehumidifying a conditioned space is provided. The system includes a housing having: a static desiccant block fixedly coupled to the housing and comprising a desiccant media; a fan configured to direct outside air across the desiccant media during a first operating phase and a second operating phase and configured to direct conditioned air across the desiccant media during a third operating phase. The system further includes a control system operatively coupled to at least one of the fan, and which includes a plurality of sensors selectively positioned inside the housing and inside the conditioned space, the plurality of sensors are configured to measure at least one air parameter of the outside air during the first operating phase and configured to measure the at least one air parameter of the conditioned air during the third operating phase.
