Abstract: The present disclosure relates to a diffuser which is connected to a duct and discharges air that is guided by the duct, and the diffuser according to the exemplary embodiment of the present disclosure includes: a diffuser frame which has a discharge port having a slot or quadrangular shape; a damping bar which is installed in the discharge port of the diffuser frame so as to be movable upward and downward, closes the discharge port of the diffuser frame while being moved upward, and opens the discharge port of the diffuser frame while being moved downward; a motor which is installed in the damping bar, and provides rotational power; and a screw shaft which has one side supported by the diffuser frame, and the other side connected to the motor, and moves the damping bar.

Abstract: Disclosed is a motorized diffuser which is shut when not in use and which reduces energy consumption in a building, eliminates the necessity of a maintenance hole, prevents contamination, has a simple configuration, and enables easy maintenance when applied in a cooling/heating system adopting a proportional air flow control scheme. According to the disclosed diffuser, a diffuser cone includes: a diffuser cone body which forms a fluid passage on the outer surface thereof which is disposed between the diffuser cone body and a diffuser casing when the diffuser cone is opened; a diffuser cone cover fixed to the diffuser cone body such that the diffuser cone cover can be assembled/disassembled to/from the diffuser cone body with a space therebetween; and a motor means fixedly installed in the space.

Abstract: The present invention relates to air conditioning equipment for an air-return area or room by using a damper-diffuser integrated motorized diffuser which has both a damper function to open or interrupt the flow of air and a diffuser function to diffuse air therearound. As the present invention uses a damper-diffuser integrated motorized diffuser in air conditioning equipment for an air-return area or room, in addition to an effect of the damper-diffuser integrated motorized diffuser, each one of an air supply duct and a discharge duct can be configured, such that the present invention can be installed within a narrow ceiling space, and as a result, room-unit air conditioning or area-unit air-conditioning is enabled and further an installation cost thereof can be low.

Abstract: The present disclosure relates to a motorized linear diffuser where an exit passage is installed along a ceiling of an interior while being connected to a duct of the interior for heating and air conditioning or ventilation. The present disclosure has been made in an effort to provide a motorized variable air volume (VAV) linear diffuser for heating and air conditioning or ventilation that can vary air volume by using a motor with a simple structure and at low costs, can be simply assembled and disassembled so that the linear diffuser can be installed or maintained and repaired in a simple way, and can maintain a sealing state when a passage is closed as well.
