TUNNEL VENTILATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To efficiently exhaust contaminated air from a tunnel and restrict the leakage of the contaminated air from the outlet of the tunnel. SOLUTION: An air blower 1 and an air exhauster 3 for discharging contaminated air from the tunnel are installed near an exist of a road tunnel and also a traffic volume detector 4 measuring the traffic volume in the road tunnel and a tunnel control device 5 determining the air volumes of the air blower 1 and air exhauster 3 based on the measured values of the traffic volume is provided.
