ABSTRACT:
The present invention discloses that outside air flows into an APU room by using a difference in pressure of the inside and the outside of the APU room during driving of a bus to induct a natural convection in the APU room and thus cool an air drier provided in the APU room, and is discharged from the APU room. Accordingly, an increase in temperature of air drier is prevented and the high temperature compressed air generated in compressor is subjected to active heat exchanging in respects to the outside while passing through air drier, thereby preventing formation of moisture according to a change in temperature of the compressed air.
