城市综合管廊通风系统设计
Ventilation system design for urban utility tunnel
摘要：
结合工程实例，探讨了城市综合管廊通风系统功能、设计原则、各舱室的通风量计算方法，以及通风系统的控制与运行策略。通过总结综合管廊内不同管线的散热量计算公式，探讨了各舱室内需要排出的余热量的计算方法，并考虑到电缆的实际最大载流量出现在不同的时间，提出了利用同时使用系数对舱室内电缆总散热量进行修正。

Abstract：
Based on an engineering project, discusses the function, design principle, ventilation calculation methods and the control and operation strategies of ventilation system for urban utility tunnel. Summarizes the heat release calculation formula of the different pipelines in urban utility tunnel, and discusses the waste heat calculation method of each compartment. Considering that the maximum current carrying capacity of each power cable occurs at different times, proposes the coincidence factor to correct the total waste heat for power cables in different compartments.
