ABSTRACT:
The present invention pertains to an air processing system for an enclosed area that includes a plenum, an air processing unit communicating with the plenum and responsive to a temperature sensing means, air-passing light fixtures for lighting the enclosed area, duct means through which the air processing unit 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 duct means, and exhaust means for exhausting air from the plenum to the atmosphere. The damper means are constructed and arranged so as to maximize the use of heat from the light fixtures whenever heat is required in the enclosed area and to discharge such heat from the light fixtures to the atmosphere in order to reduce the cooling requirement when cooling is required in the enclosed area.
