Title:
ELEVATOR PRESSURIZATION
Document Type and Number:
WIPO Patent Application WO/2016/085722
Kind Code:
A3
Abstract:
A method of pressurizing an elevator (112) includes pressurizing a lobby (102) to a pressure (P2) different from ambient pressure (P1) at the elevation of the lobby (102). Pressurizing the lobby (102) can generally include pressurizing the lobby (102) to a pressure (P2) between the ambient pressure (P1) at the elevation of the lobby (102) and an ambient pressure (P6) at a destination elevation. This can allow for at least some equalization of the inner ears of passengers to take place while passengers are waiting to pass from the lobby (102) into the elevator cab (112), or waiting to pass from the lobby (102) into the ambient pressure (P1) of the building outside the lobby (102).
