The present invention relates to a pressure control system and method for a roof-mounted air conditioner for high-speed rail vehicles. More particularly, the present invention provides a pressure control system and method for a roof-mounted air conditioner for high-speed rail vehicles that protect the health and improves the comfort of passengers in a cabin by continuously supplying fresh air to the air conditioner while the high-speed rail vehicle is traveling in a tunnel section, thereby preventing a decrease in oxygen concentration and an increase in carbon dioxide concentration, as well as enabling more constant and precise control of the air input as the air is supplied to the air conditioner while gradually reducing the pressure if an air tank consists of multiple tanks, as well as enabling more compressed air to be stored at the same time. 본 발명은 고속철도 차량용 지붕탑재형 공기조화기의 압력 조절 시스템 및 방법에 관한 것으로, 고속철도 차량이 터널 구간에서 주행 중 공기조화기에 신선한 공기를 지속적으로 공급함으로써 산소 농도 감소 및 이산화탄소 농도 증가를 방지하여 객실 내 승객의 건강을 보호하고 쾌적성도 향상시킴은 물론 공기탱크를 복수의 탱크로 구성하는 경우 단계적으로 압력을 낮추면서 공기조화기에 공기를 공급함에 따라 공기 투입량을 더욱 일정하고 정밀하게 제어할 수 있을 뿐만 아니라 동시에 더 많은 압축 공기를 보관할 수 있는 고속철도 차량용 지붕탑재형 공기조화기의 압력 조절 시스템 및 방법을 제공한다.
