Embodiment Construction

[0016] FIG. 1 schematically shows an elevator system 20 within a building 22 . In this example, the building 22 is a high-rise building that includes a first lobby level 24 and a lower level 26 that include access (ie, doorways) 28 and 30 that enable individual passengers to enter or exit the building 22, respectively. In one example, passageways 28 and 30 provide openings for potential airflow communication between interior spaces on building floors 24 and 26 and the exterior of the building.

[0017] A first shaft 32 , in one example an elevator shaft, extends between the building floor 24 and at least one second floor 36 located above the building floor 24 . In this example, another shaft 34 extends between the same building floors. Shafts 32 and 34 allow individual passengers entering building 22 to building floor 36 where they can then pass through one or more shafts 40 to higher floors within the building. In one example, multiple elevator shafts are provided and one s...

Abstract

An elevator system (20) includes at least one vertical shaft (32) extending between at least two levels (24, 36) of a building (22). One of the levels (24) includes at least one passageway (28) between an interior of the building and the outside environment. At least one second shaft (40) extends between the other building level (36) and at least one other level within the building. The interior of the second shaft (40) is isolated from airflow on the building level (24) that includes the passageway (28) to the outside environment. Disclosed examples include enclosures (52) for isolating the first shaft (32) from airflow on at least one of the levels to which the first shaft provides access.

Description

technical field [0001] The present invention is primarily concerned with controlling airflow within a building so as to minimize the stack effect potentially associated with shafts within the building. Background technique [0002] There are a variety of situations where airflow management and air pressure management within buildings is desired and necessary. Various building configurations, for example, require the control of airflow between the interior and exterior of a building to prevent undesirably large airflows through pathways (eg, doorways) that provide access to the building. In some cases, the temperature difference between the inside and outside of the building and the construction of the building itself can cause a pressure difference between the inside and the outside of the building, which may create different pressure differences between the inside and outside of the building. Large air currents or even gusts are desired. This problem can be exacerbated by...
