Abstract

A dehumidification system for dehumidifying a conditioned space. The system is comprised of a motionless desiccant block for dehumidifying air within the conditioned space. The system is configured to operate in one of two modes. In a first dehumidifying mode the system draws air from the conditioned space, dehumidifies the air, and returns the air to the conditioned space. In a second regeneration mode the system draws air from outside the conditioned space, heats the air, passes the heated air through the desiccant to dry the desiccant, and expels the air back outside the conditioned space. The system is configured with pivoting dampers to select air source and air destination for the two modes of the system. The system includes blowers in order to motivate the flow of air and a regenerative heater for use during regeneration mode. By utilizing a motionless desiccant block the system avoids the expense and maintenance of desiccant wheels and wheel motors.
