Controlling the air pressure at each of a plurality of levels (A, B, C, D) within the useable or occupied space of a building (20) allows for controlling a pressure differential between the useable or occupied space and an interior of the shaft (40). Maintaining appropriate pressure differential levels allows for minimizing or avoiding the stack effect that otherwise results in undesirably large drafts between the building interior and the outside, surrounding environment.

Abstract: In an elevator system having an elevator control unit and an atmospheric pressure control unit, an elevator operation state monitor monitors the operation state of the elevator control unit, and an atmospheric pressure control state monitor monitors the operation state of the atmospheric pressure control unit. When a trouble in the elevator operation or atmospheric pressure control is detected, a minor/major trouble judgment unit judges the seriousness level of the trouble, and a rescue mode selector selects a rescue mode. In this case, when the atmospheric pressure control is abnormal, it is judged a major trouble, and a mode to ensure ventilation in an elevator car is selected. This enhances the safety in a highly airtight elevator such as a superhigh-speed high-rise elevator.

The inventive device includes a seat having a plurality of air nozzles, an exhaust fan, and a pair of side members removably attachable between the seat and the exhaust fan.

The welding fumes are thereafter drawn into an intake manifold of the exhaust fan and then released a safe distance away from the welder through an exhaust tube. Flange about the intake manifold reduces the amount of fresh air drawn into the intake manifold.

Abstract: A system and method for maintaining elevator use during a fire includes a blower and a damper at opposite ends of an elevator shaft to create a full volume current of fresh air that engulfs a conventional elevator car traveling between floors. The unidirectional airflow provides a curtain of air that "washes" any smoke away from the exterior of the elevator car. When the car stops at a floor, the damper closes to force the fresh airflow onto that floor. Fresh air is chosen from one of several fresh air supplies by sensing the quality of the air at the supplies.

The reinforcing plate has rows of apertures formed in generally V-shaped grooves aligned with the ventilation slots. The grooves space the apertures from the carrier.

Abstract: An apparatus for ventilating high speed elevator cars during the travel with closed doors includes upper and lower ventilation systems having primary air openings formed in troughs located in the upper and lower portions of the car body. The pressure of the incoming air is relieved and the air is smoothed in steps in air chambers and air channels such that the air flows free of drafts and noiselessly into the interior of the car. The ventilation of the elevator car takes place through the ventilation apparatus in the direction of travel of the car, since both the ventilation systems provide flow through in both directions of travel of the car.
