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

摘要

The present invention relates to a device for reducing the pressure difference between a common part and an exclusive part in a building generated by a stack effect, and the present invention relates to a user of a building in order to open and close the entrance of the exclusive part where the user of the building enters and exits the exclusive part and the common part on the same floor a motion sensor for detecting an approach to the entrance; 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 the user approaches the entrance through the motion sensor, a pressure difference between the exclusive unit and the common unit is calculated and compared with a pressure set value (Pa) for opening the window of the common unit, the When the calculated pressure difference between the exclusive unit and the common unit is equal to or greater than the pressure set value (Pa) for opening the common unit window, the common unit window is opened through the window opening and closing device to allow air to flow into or out of the building. , It provides an apparatus for reducing the pressure difference between the common part and the exclusive part in a building generated by the stack effect including a control device for reducing the pressure difference between the exclusive part and the common part. According to the present invention, by resolving the excessive pressure difference due to the stack effect by opening the individual windows of each floor, it is possible to reduce the continuous pressure difference due to the design change of the building and reduce the intermittent pressure difference, By opening the windows and allowing outside air to flow in, the excessive pressure difference due to the stack effect can be eliminated without using the air conditioning system in the building, and the pressure difference due to the stack effect, which increases as the distance from the neutral zone increases, can be reduced in each floor. By individually controlling the windows of the common area, it includes the effect of more timely and easier maintenance and management.
