本文将讨论消防部门在建筑排烟方面的困难，并描述一项显著改进了处理该问题方法的创新。在过去的四分之一个世纪或更长的时间里，通常的做法是使用负压通风进行排烟。使用正压法的实验和经验证明，这是大多数情况下的首选方法。已开发了大容量空气流动系统，以便于用结构外部的新鲜空气替换污染空气。单位:I-PCITION:研讨会，ASHRAE交易，1988年，第94卷，pt。德克萨斯州达拉斯1号

This paper will address the difficulties that fire departments have in smoke removal from buildings and descriDe an innovation that has significantly improved the methodology of handling the problem. Common practice over the past quarter century or more has been to use negative pressure ventilation for smoke removal. Experiments and experience using positive pressure methodology have proved this to be the method of choice in most cases. A high volume air movement system has been developed to facilitate replacement of the contaminated air with fresh air from outside the structure.Units: I-P
