 In order to reduce energy consumption of ventilation and air conditioning system in underground railway stations, proposes an energy saving reform scheme for the ventilation and air conditioning system and the ventilation system of environmental control room in the public area of an underground railway station in line 1 of a city. Through analysis and calculation, concludes that the air conditioning system in the small-end public area of the station can be transformed into a single fan system to reduce the operation energy consumption of the return and exhaust fan and the small outdoor air handling unit, the energy consumption of the existing two-speed fan in the ventilation system of the station environmental control room is high when running at low speed, so replacing with a two-speed fan equipped with YDT special motor can reduce the operation energy consumption obviously.
