ECONOMIZING CYCLE VENTILATION SYSTEM FOR CLIMATED AND CONFINED RACK

摘要

This is a duct ventilation system with accessories, which includes an inlet duct (33) located just before the return of the air conditioning machine (3), and a discharge duct (34) just after the air has passed through the rack. , which expels the heated air from the return to the external environment and admits external air to the return of the air conditioning machine (3) and the air flow from the enclosure of the hot plenum (32) to the ventilation ducts by dampers (35) of overpressure or motorized, and air flow at the inlet (33) will be sucked in by the air conditioning machine (3) while the heated air is discharged into the discharge duct (34).
