Ventilation and smoke exhaustion method of underground stereo parking garage
The invention discloses a ventilation and smoke exhaustion method of an underground stereo parking garage. The ventilation and smoke exhaustion method is characterized in that an underground bottom channel is arranged at the bottom of the underground stereo parking garage; an underground exhaust duct is arranged on each of the two sides of the underground stereo parking garage; the lower parts of the underground exhaust ducts are communicated with the underground bottom channel; an annular exhaust duct is arranged on the outer side of the top of an underground parking place structure in each layer; a parking place air outlet is formed in the outer wall of the underground parking place structure in each layer; the underground exhaust ducts are communicated with all the annular exhaust ducts; a ground exhaust duct is arranged on each of the two sides of a ground parking room; the lower part of each ground exhaust duct is communicated with the corresponding underground exhaust duct; the upper parts of the two ground exhaust ducts are connected through a horizontal air duct; two top exhaust fans are arranged on the horizontal air duct; a smoke vent electric valve and a temperature-gas detector are arranged on each parking place air outlet. According to the invention, under the pumping action of the top exhaust fans, harmful gases of the underground stereo parking garage can be removed, and the temperature of the underground stereo parking garage is decreased.
