The outside air introduction grill inducted natural convection inside air influx room

摘要

The present invention is traveling with an external differential pressure between the APU room (1) during the running of the bus interior style entering the room in APU (1) therein, which is the outside air introduced APU room (1) as the natural convection cooling of the APU within the room ( 1) an air dryer (3) is installed in the inside , and then flows into the APU room (1) as with the series of processes for discharging air out again made to prevent the temperature increase of the air dryer (3) , the high-temperature compressed air generated in the compressor (A) and the external active heat exchange while passing through the air dryer (3) this feature made it is possible to avoid most of the water formed as a function of temperature of the compressed air .
