Differential pressure reduction device in common part and dedicated part in building caused by stack effect

摘要

The present invention relates to an apparatus for reducing differential pressure between a common part and a private part in a building caused by a stack effect, and the present invention is to open and close the entrance of the private part through which a user of the building enters the private part and the common part of the same floor. A motion sensor that detects approaching the front door; A window opening and closing device for automatically opening and closing the windows of the common part installed to ventilate the common part of the building; And when it is sensed that a user approaches the front door through the motion sensor, a pressure difference between the exclusively oiled portion and the common portion is calculated and compared with a pressure set value (Pa) for opening the common portion of the window, and the When the calculated pressure difference between the exclusively oiled part and the common part is greater than or equal to the pressure set value (Pa) for opening the common part window, the common part window is opened through the window opening and closing device and air is introduced or discharged into the building. It provides a differential pressure reduction device between the shared portion and the exclusive portion of the building generated by the stack effect, including a control device for reducing the pressure difference between the exclusively oiled portion and the shared portion. According to the present invention, the excessive pressure difference due to the stack effect can be resolved by opening individual windows of each floor, thereby reducing the continuous pressure difference due to the design change of the building and reducing the intermittent pressure difference. By opening the windows and introducing outside air, it is possible to resolve the excessive pressure difference due to the stack effect even without using an air conditioning system in the building. By controlling the windows and doors of the common part individually, it includes the effect of enabling more timely and simpler maintenance and management.
