Abstract
An apparatus is provided which combines in a single, relatively compact housing the necessary components to efficiently exchange stale room air with fresh outside air. The apparatus includes a single, continuous duct having openings at each end. A heat storing matrix is disposed within the duct. A fan is also placed within the duct. The fan is capable of producing a substantially axial air flow through the duct. The fan is moveable between two positions: a first position wherein air flow is in a direction from the first end to the second end of the duct and a second position wherein air flow is reversed. The apparatus includes means for moving the fan from the first position to the second position such as a solenoid.

Apparatus for exchanging air within an enclosure with outside air, comprising:
- a duct providing air communication between a source of said outside air and said enclosure;
- a heat storing matrix disposed within said duct;
- a single fan disposed within said duct and adapted to produce substantially axial air flow within said duct, said fan being mounted for movement between a first position, wherein air flow is produced from said source of outside air to said enclosure, and a second position, wherein said air flow is reversed;
- and
- means for moving said fan at preset intervals from said first position to said second position.
