ABSTRACT:
The present invention pertains to an air processing system for an enclosed area having a plenum. The system includes an air processing means in communication with the plenum and responsive to a temperature sensing means, air-passing light fixtures for lighting the enclosed area, return air means through which the air processing means receives return air via two separate paths, one being in heat exchange relationship with the light fixtures, damper means for controlling the passage of air through the return air means, power exhaust means and ventilation means for exhausting air from the plenum and enclosure to achieve volume balance. The damper means is constructed and arranged so as to maximize the use of heat from the light fixtures whenever heating is required in the enclosed area and to discharge heat from the light fixtures to the atmosphere whenever cooling is required to reduce the cooling requirement.
