SYSTEM POWERED DAMPER BLADE ASSEMBLY FOR USE IN AN AIR CONDITIONING SYSTEM

摘要

SYSTEM POWERED DAMPER BLADE ASSEMBLY FOR USE IN AN AIR CONDITIONING SYSTEM Many multiroom structures, such as office buildings and schools, constructed during the past several years, include air conditioning systems to deliver either relatively warm or cool conditioned air from a central source thereof to each of the enclosures or rooms in the building. Typically, one or more ducts are employed to deliver the air to each enclosure. Very often, a damper blade assembly or similar mechanism is installed in the duct to regulate the flow of air to one or more diffusers or discharge outlets located in the enclosure being conditioned by the discharge of air thereinto. The movement of the damper blade assembly may be responsive to changes in the conditioned air supply pressure and/or changes in the temperature of the enclosure.
