超高层建筑空调水系统竖向分区分析

Analysis of Vertical Zoning of Air Conditioning Water System of Super-high-rise Buildings

空调水系统设计是超高层建筑空调设计的重点与难点,而空调水系统的竖向分区又是水系统设计的重点与难点。本文介绍了包括设置中间换热器及分区设置冷热源的各种竖向分区形式,分析了各种形式中空调水系统的水压分布和设备承压情况,以及各种分区形式的优缺点和重点要考虑的问题,最后介绍了几个典型超高层水系统分区案例。

The key and difficult point of super-high-rise building design is the designing of its air conditioning water system,whose key and difficult point is the vertical zoning.This paper introduces different vertical zoning patterns including the setup of intermediate heat exchanger and the vertical partition settings of the cold and heat source station,and analyzes the hydraulic pressure distribution and the pressurebearing situation of the equipment of different vertical zoning patterns and their advantages and disadvantages.Some important issues are taken into consideration.At last,a couple of typical cases of vertical zoning of air conditioning water system of super-high-rise buildings are introduced.
