Patent ID: 7340906

Claim:
A method of conditioning air for a comfort zone, the method comprising: conveying the air sequentially through an outside air inlet, an intermediate air chamber, an outside air outlet, an upstream air passageway, through a desiccant wheel, through an intermediate air passageway, back through the desiccant wheel, and out through a downstream air passageway; cooling the air as the air passes from the outside air inlet to the intermediate air chamber; heating the air as the air passes from the intermediate air chamber to the outside air outlet; releasing moisture from the desiccant wheel to the air as the air passes from the upstream air passageway to the intermediate air passageway; cooling the air as the air moves from the desiccant wheel to the downstream air passageway; and absorbing moisture from the air as the air moves back from the desiccant wheel upon traveling from the intermediate air passageway to the downstream air passageway.
