Abstract: When the household air-conditioner is running in the high humidity environment in summer, the condensation and dripping of the wind deflector occurs, which causes significant inconvenience to the user. In order to quantify the evaluation method of wind deflector condensation, proposes a wind deflector condensation simulation method based on dehumidification model, and carries out the wind deflector condensation prediction analysis of a certain model of home empty hang-up machine. The results show that the condensation simulation method used can predict the condensation location well, and the condensation dripping risk at the bottom of the guide plate can be greatly improved by optimizing the contour line at the bottom of the large guide plate and matching the design with the air duct contour line.
