A TUNNEL VENTILATOR BY USING NATURAL VENTILATION METHOD

摘要

PURPOSE: A tunnel ventilator using a natural ventilation method is provided to prevent noise and heat and reduce electrical energy due to no consumption of electrical energy, since polluted air is naturally discharged. CONSTITUTION: A tunnel ventilator using a natural ventilation method comprises a water tank intake unit, an external air inflow unit(200), and an air vent(15). The water tank intake unit discharges cold air and absorbs smoke and gas through a smoke gas inlet(4). The external air inflow unit is formed on left and right sides of a tunnel to circulate and supply external air to the inside of a tunnel with cold air. As convection current is generated by the cold air and the external air, the air vent absorbs polluted hot air discharged from vehicles.
