<p>PURPOSE: A static pressure compensation type ventilation device for an underground parking lot and a ventilation method using the same are provided to increase an inducing effect and to reduce noise by preventing backflow and vortex as induced air is guided by a second nozzle or third nozzles. CONSTITUTION: A static pressure compensation type ventilation device for an underground parking lot comprises a casing(10), a blower(20), a blowing fan(30), a second nozzle(40), and multiple third nozzles(50). The blowing fan is installed inside the blower. The inner diameter of the second nozzle is cylindrically tapered forward. The central axis of the second nozzle is positioned on the center axial line of the blower at the center part of a front panel of the casing. A first nozzle(23) whose inner diameter is tapered forward is formed in an exhaust port(22) of the blower. The inner diameter of the third nozzles is tapered forward.</p> |
