Patent ID: 7373786

Claim:
A desiccant dehumidification system comprising: a housing partitioned into a first and second air chamber each for passing air therethrough, each said air chamber having an inlet for intake of air and an outlet for exhausting air; a rotating desiccant wheel positioned inside said housing and across said air chambers; an air transmitting means positioned within said first air chamber for drawings return air from a structure into said first air chamber and passing said air across said desiccant wheel to remove moisture from said return air and exhausting into the structure as conditioned air; an air transmitting means positioned within said second air chamber for drawing a source air into said second air chamber, across said desiccant wheel to remove moisture from said desiccant wheel and exhausting from said second air chamber; an air heating means positioned in said second air chamber upstream of said desiccant wheel for heating said source air to be passed over said desiccant wheel; and a conduit being operationally connectable between said air transmitting means in said first air chamber and said air heating means for passing pressurized return air to said air heating means, said conduit also being operationally connectable between said air transmitting means in said second air chamber and said air heating means for passing pressurized source air to said air heating means.
