Experimental Study on the Design of Pressurization System in High-Rise Buildings

By experimental study, a design for pressurization system in a multiple injection system with upper injection is discussed and the velocity distribution in a shaft is educed by the approach method. This velocity has a relation with volume flux from pressurization fan, section area of pressurization shaft and height of shaft. In factual situation, there is an important assistant meaning on researching the design of pressurization system in high-rise buildings.
