ABSTRACT:
An air conditioning system comprises an air conditioning unit, a blower for blowing conditioned air, a polygonal branch chamber of prescribed volume, a main duct with damper for delivering conditioned air from the blower to the polygonal branch chamber and branch ducts with dampers for delivering the conditioned air from the polygonal branch chamber to a plurality of discrete spaces. The polygonal branch chamber ensures quiet operation. An electrical circuit board is mounted on the bottom of the polygonal branch chamber and all wiring required for control of the dampers and other components of the system are connected with this board to enable maintenance work to be conducted at a signal location. A circular inspection hole with removable cover is formed in the bottom of the polygonal branch chamber to provide easy access to its interior. The dampers are integrated into damper pipe units including actuators, opening degree regulators and other components required for damper operation, further simplifying installation and maintenance work.
