Document Type and Number:
WIPO Patent Application WO/2024/025242
Kind Code:
A1
Abstract:
A constant air volume electric damper and a centralized high-efficiency constant static pressure ventilation system comprising same are disclosed. A constant air volume electric damper according to an embodiment of the present invention comprises: a cylindrical body having a flow channel formed therein; an opening/closing part coupled to the body to open or close the flow channel; a sensing part coupled to the body to be able to measure the air volume passing through the flow channel; and a control part for controlling the opening/closing part on the basis of information, which is transferred from the sensing part, to uniformly maintain air volume, wherein the sensing part comprises: a radial holder coupled to the inner circumferential surface of the body; a generator coupled to the center of the holder to convert rotational energy into electrical energy; a rotating fan coupled to the generator to be rotatable; and a calculation part for measuring an air volume by using electrical energy generated in the generator.
