VENT TRUNK OF AIR CONDITIONER

摘要

PURPOSE: A vent trunk of an air conditioning device is provided not to be put under back pressure through a fan off even if a portion of fans are off, thereby to restrain the backflow of air on the inside and to heighten the supply efficiency of air. CONSTITUTION: A vent trunk of an air conditioning device contains a main body(10) offering a route for air flow, many fan housings(20) installed to the inside of the main body to be parallel with the main body, a fan(30) installed to each fan housing to offer blowing force for air flow, a damper(40) installed to the inside of each fan housing to be rotatable to open and shut the air flow, a damper driving unit(50) rotating each damper, and a control unit detecting the operation of each fan to cut off the air flow through the fan housing with the fan off.
