The Stack effect reduced system through air current circulating of high-rise building

摘要

The present invention relates to a system to reduce a stack effect through air current circulation in a vertical passage of a high-rise building, capable of reducing a stack effect occurring in a vertical passage of a high-rise building. According to the present invention, when a stack effect due to temperature and pressure differences in a vertical passage, such as a staircase, an elevator shaft, etc., of a high-rise building in winter, a pressure deviation between low and high floors with respect to the vertical passage of the high-rise building is minimized to prevent an air convection effect and remove a temperature deviation, thereby reducing the stack effect. In particular, air conditioned to the vertical passage of the building is able to be circulated inside the building, thereby preventing a heat loss inside the building and reducing heating energy thereby. Moreover, a pressure of a plurality of vertical passages is able to be adjusted in accordance with a pressure control of each compartment of the vertical passage, thereby reducing energy in accordance with operation of equipment. According to the present invention, the system comprises high and low floor pressure sensors (100, 200), a blowing fan (300), and a controller (400).
