Experimental research in the condensation performance of three types of glassfiber composite air duct flange

Sums up and designs three kinds of glassfiber composite air duct flanges, Ftype, Ttype and Jtype, tests their temperature and air duct surface temperature of Jtype. Analyses the behavior of Jtype flange temperature changing with ambient temperature and air temperature in duct, presents the temperature distribution pattern of the air duct with Jtype flange. The results show that only Jtype flange can not produce condense water, it is much better than the F and Ttype flange.
