摘　　要：为了研究诱导通风系统对地下停车场火灾烟气控制的影响。文章以某地下停车库为模型,应用FLUENT软件分别模拟不同诱导风机出口风速、不同排烟量时停车场内烟气温度以及CO2浓度的分布情况。模拟结果显示:诱导通风系统可以有效控制火灾烟气任意扩散,加速烟气向排烟口运动;降低火源上游烟气温度和烟气浓度,从而提高能见度,为人员逃生和消防人员进行救援提供一条有效路径。In order to study the influence of induced ventilation system on fire smoke control in underground parking lot. This paper takes an underground parking garage as a model and simulates the distribution of flue gas temperature and CO2 concentration in the parking lot with different induced fan outlet wind speed and different exhaust smoke quantity- respectively by using fluent soft- ware. The simulation results show that the induced ventilation system can effectively control the arbitrary diffusion of fire smoke, ac- celerate the movement of smoke to the flue gas outlet, reduce the smoke temperature and smoke concentration in the upper reaches of the fire source, and thus improve the visibility-, so as to provide an effective path for the personnel escape and rescue fire person- nel.
