在加拿大国家研究委员会（National Research Council of Canada）的实验消防塔中进行了测试，以研究大型火灾引起的通过电梯井的烟雾运动，并确定机械增压在保持电梯井和大厅可供残疾人疏散和消防员使用方面的有效性。测试表明，需要进行压力控制应对由于开门而导致的增压损失。开发方程式是为了帮助设计压力控制系统，该系统涉及带有反馈控制的可变送风量或电梯井或大堂壁上的减压阀。在塔中进行的试验表明，对于这两种压力控制方法，送风量和压差的测量值和计算值的比较是一致的。 单位:双引文:研讨会，ASHRAE交易，1987年，第93卷，第。田纳西州纳什维尔2号

Tests were conducted in the experimental fire tower at the National Research Council of Canada to study smoke movement through elevator shafts caused by a large fire and to determine the effectiveness of mechanical pressurization in keeping the elevator shaft and lobbies tenable for evacuation of the handicapped and for use by firefighterso The tests indicated that pressure control is required to cope with loss of pressurization due to open doors° Equations were developed to assist in designing pressure control systems involving either a variable supply air rate with feedback control or relief dampers in the walls of the elevator shaft or lobbies. Tests conducted in the tower indicated that for both methods of pressure control, comparison of measured and calculated values of supply air rates and pressure differences are in good agreement.Units: Dual
