摘　　要：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PHOEN ICS,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;分析火灾后空调、防排烟兼用系统对单室空调房间火灾发展,以及对室内人员疏散产生的影响.模拟计算的结果证明了兼用系统火灾后在排烟、降温、减压、增加疏散时间等方面的实用性和可行性.Selecting a separate room under the air- conditioning system in a tall building as the study object, and using the computational fluid mechanics software PHOENICS, the author achieves numerical simulations of the fire process in different air- condition system working conditions, which include the system of air - condition, smoke control and the dual function. The influences of the dual function system on the fire process and influences on evacuation of people from the fire room are analyzed. The results of the simulations prove in theory the practicability and the feasibility of the dual function system in smoke control, temperature decreasing, decompression, delaying the evacuating time and so on.
