The present invention relates to a method for controlling a ventilation system for railway vehicles and, more specifically, to a method for controlling a ventilation system for railway vehicles, capable of improving indoor air quality and airtightness performance by opening and closing a damper of the ventilation system in accordance with a vehicle speed during tunnel operation. The method for controlling a ventilation system for railway vehicles comprises the steps of: (a) calculating a tunnel specification, a vehicle specification, and a driving diagram as an input value for analyzing a tunnel pressure wave, and calculating an air flow resistance coefficient of the ventilation system; (b) setting an initial speed value of a railway vehicle for controlling a damper of the ventilation system; (c) checking whether airtightness of the railway vehicle is satisfied, and determining a railway vehicle speed reference value for controlling the damper; and (d) reflecting damper operation control logic for improving vehicle airtightness and air quality to the ventilation system.

    본 발명은 철도차량용 환기시스템 제어방법에 관한 것으로서, 특히 터널 운행시 차량속도에 따라 환기시스템의 댐퍼를 개폐 제어함으로써, 실내 공기질 및 기밀성능 향상을 이루도록 하는 철도차량용 환기시스템 제어방법에 관한 것이다. 구성은 철도차량용 환기시스템 제어방법에 있어서, (a) 터널 압력파 해석을 위한 입력값으로 터널 제원, 차량 제원, 주행 선도 산출과, 환기시스템의 공기 유동저항계수를 산출하는 단계; (b) 환기시스템의 댐퍼 제어를 위한 철도차량의 초기 속도 값을 설정하는 단계; (c) 철도차량의 기밀성 만족여부 확인 및 댐퍼 제어를 위한 철도차량 속도 기준 값을 결정하는 단계; (d) 차량기밀성과 공기질 개선을 위한 댐퍼 동작 제어 로직을 환기시스템에 반영하는 단계; 로 이루어지는 것을 특징으로 한다.
