Title:
TUNNEL AIR-EXCHANGE DEVICE USING A NATURAL AIR-EXCHANGE METHOD
Document Type and Number:
WIPO Patent Application WO/2011/030997
Kind Code:
A1
Abstract:
The present invention relates to a tunnel air-exchange device, and more specifically to one in which: the air inside normal tunnels including tunnels through which vehicles run is cleaned and polluted internal tunnel air is expelled to the outside, to which end cold air, supplied to water tanks of different sizes provided in line at set intervals in the floor inside the tunnel, is used to ensure that the heavy soot and gases in the polluted hot air generated by vehicles, are sucked into the water tanks while the lighter foul air is discharged through chimneys by convection, thereby creating a pleasant tunnel environment by always maintaining clean air inside the tunnel; and which also extinguishes fires by spraying fire-extinguishing water during tunnel fires. Accordingly, the present invention combines a chimney effect with natural convection provided by the water tanks to exchange the air inside the tunnel and naturally expel polluted air, which is in contrast to exhaust fans of the prior art because there is no generation of noise or heat, and expenses can be reduced since there is no electrical consumption.
