Abstract
An air circulation and ventilation system for an enclosure. The system includes a fan assembly subsystem with a housing defining a manifold. The housing has a first intake aperture configured to receive air from within the enclosure, a first outlet aperture configured to emit air from the manifold to outside the enclosure, and a fan configured to draw air in through the first intake aperture. The system includes a pressure equalization subsystem having a port configured to allow additional air into the enclosure. The port includes a damper for selectively opening and closing the port. The system also includes a switching subsystem with a switch operably coupled to the fan and the damper. The switch selects between a first mode where the damper is closed and the fan is off and a second mode where the port damper is open and the fan is on.
