Abstract: 본 발명은 공기 순환 기능을 갖는 복층식 열차에 관한 것으로; 1층 객실과 2층 객실을 갖는 공기 순환 기능을 갖는 복층식 열차에 있어서, 상기 1층 객실의 천장에서 창측 하부로 정화된 공기를 공급하고 상기 2층 객실의 바닥에서 창측 상부로 정화된 공기를 공급하는 환기장치가 구비되는 것을 특징으로 한다.
본 발명에 따른 열차는 복층식으로 형성하여 많은 승객을 효율적으로 수용하면서도 실내에서 공기가 순환할 수 있는 공조 기능을 통해 객실 내 환기를 효율적으로 수행할 수 있다. 특히 본 발명은 2층 객실은 좌석식으로 하고 1층 객실은 입석을 허용할 수 있는 구조로 좌석을 배치하여 승객의 수용 효율을 높임은 물론 1층 및 2층 객실의 공기순환 구조를 다르게 형성하여 구조가 단순하면서도 전체적인 열차 내 공기 순환 효율이 높다.
