Patent ID: 7044851

Claim:
An air handling system for a specialized environment in a facility, the air handling system comprising: (a) a facility air handling system which comprises (i) an air handler connected to the outside air for exhausting return air from the specialized environment and for drawing outside air into the specialized environment; (ii) an air handler diffuser operatively connected to the specialized environment for providing air from the air handler to the specialized environment; (iii) an air return register through which air is provided from the specialized environment to the air handler; (iv) a first set of air handler ductwork for providing a pathway for air traveling from the specialized environment to the air handler; and (v) a second set of air handler ductwork for providing a pathway for air traveling from the air handler to the air handler diffuser; (b) an air recirculation system which comprises (i) a blower for drawing air from the specialized environment for recirculation; (ii) a recirculation diffuser operatively connected to the specialized environment for recirculating air back to the specialized environment by action of the blower; and (iii) recirculation ductwork providing a pathway for air traveling from the blower to the recirculation diffuser, wherein the air recirculation system is permanently isolated from the outside air and is independent from the facility air handling system so that all air drawn from the specialized environment by the blower is returned to the specialized environment; wherein said air recirculation system includes a first corner ductwork located in a first corner of the specialized environment and extending from floor to ceiling; and wherein said first set of air handler ductwork of said facility air handling system includes a second corner ductwork located in a second corner of the specialized environment and extending from floor to ceiling, said first and second corners being located at a common end of said specialized environment.
