Energy saving analysis of underground railway ventilation in severe cold zone

Analyses the operating energy consumption of different ventilation modes in underground railways in severe cold zone under the conditions of meeting the hot and humid environment and safe operation of stations and sections by using the STESS software. Lists the composition and operation modes of different ventilation systems, and analyses the energy consumption and economic benefits. It is concluded that the total energy consumption of the whole year’s operation modes should be taken into account in the design of underground railway ventilation in severe cold zone, and the relative energy consumption of vehicle air conditioning and heating equipment should not be ignored for the winter closed operation mode.
