Patent ID: 8671876

Claim:
An energy management system for a building, said energy management system comprising: an air intake unit adapted to draw air from outside the building into an interior of the building, said air intake unit adapted to condition the air to a target temperature; a paint spray booth in which paint is applied to at least one product, said paint being applied in the presence of the conditioned air; a water wash unit having a water basin configured to hold water, said water wash unit adapted to remove paint particulate from the conditioned air; and a pipe subsystem extending between the water basin and the air intake unit and including a pump, said pump adapted to circulate a liquid through the pipe subsystem between the water basin and the air intake unit wherein the circulated- liquid transfers heat between the water of the water basin and the air intake unit in such a manner so as to assist the air intake unit in conditioning the air drawn from outside the building, wherein the pipe subsystem further includes a first heat exchanger positioned within the water basin and a second heat exchanger positioned inside said air intake unit, said first heat exchanger adapted to transfer heat between the water of said water basin and the liquid inside said pipe subsystem and said second heat exchanger adapted to transfer heat between the liquid inside said pipe subsystem and the air drawn from outside the building into the air intake unit.
