Study on air conditioning process control design issues of underground railway station

Summarizes the problems occurred in the system commissioning of underground railway engineering project, suggests to determine the control body, and convert text description to the logic control relation or formula. Considers that the equipments and valves which do not take part in the fire rescue should be in “closed” status, and interprets the common problems in the process control design based on the engineering cases which can guide the future underground railway design.
