防排烟系统与空调系统火灾后兼用的模拟研究

The Simulation of One System Serving Both Air-conditioning and Smoke Control During a Fire

本文以某高层建筑的单室空调房间为研究对象,利用计算流体软件PHEONICS,分别对空调系统、排烟系统、兼用系统等空调系统的不同运行工况下单室火灾发展过程进行了数值模拟计算。分析兼用系统对空调房间火灾发展,以及对室内人员疏散产生的影响,从理论上证明兼用系统火灾后在排烟、降温、减压等方面的实用性和可行性。研究结果对于单室火灾后人员疏散和空调、防排烟兼用系统的设计都具有重要的指导意义。

Selecting a separate room of an air-conditioned high-rise building as study object, numerical simulations of the fire process in different working conditions were performed with PHEONICS. The working conditions include the system serving as air-conditioning, smoke control and the dual function of both. By analyzing the influences of the dual function system to the fire process and people evacuating from the fired room, the practicability and the feasibility of the dual function system in smoke control and air temperature decreasing during the fire process were proved. The results of the study can be used as reference in design of evacuating system during a fire, and design of the air-conditioning and smoke control dual function system in high-rise buildings.
