In data centers using Room-Oriented and Row-Oriented Air Conditioning systems and applying Fully Ducted Hot Air Collection, cooled air should be provided in front of racks. After passing through equipment, warmed air leaves back of racks. Therefore, in racks with high power consumption, in order to facilitate and increase direct air flow rate from front to end of racks, as well as to prevent the hot and cold air interference in the room, Exhausted Doors are used.
Using the Exhausted Door, the hot air generated at the rear of racks is quickly absorbed by fans embedded on, and after moving in hot air channel, exits from the upper part of the door. At this point, if the hot air channel installed above the Exhausted Door the hot air is collected by centralized system and direct back to the cooling system inlet.
