According to the characteristics of local natural environmental factors and the conditions of business and residential areas in the subway route, our company selects high-temperature resistant axial flow fans in station sections and public areas of the station to undertake the exhaust of half a station and reduce the impact of train heat on the station section. . At the same time, it works in conjunction with the combined air-conditioning unit, which operates at a low frequency during air conditioning and ventilation, which saves energy and saves electricity. A reversible high-temperature jet fan is installed in the tunnel section. When the train runs normally, the fan does not operate. When the train is blocked or fired in the relevant section Under the working conditions, it can cooperate with the tunnel high-temperature resistant axial fan to ventilate the area, eliminate smoke, and realize the safe evacuation of personnel.
