防排烟系统与通风空调系统兼用的相关技术措施 【英文篇名】 Technical measures related to a system for both smoke control and ventilation 【作者中文名】 严治军; 白雪莲; 【作者英文名】 By Yan Zhijun ★ and Bai Xuelian; 【作者单位】 重庆建筑大学; 【文献出处】 暖通空调, HV 通风空调; 兼用系统; 防烟分区; 管网阻力; 漏风量; 【英文关键词】 smoke control and extraction; ventilation and air conditioning; dual purpose system; smoke control zoning; resistance of pipe system; air infiltration rate; 【摘要】 为实现风机的兼用，提出通过划分防烟分区，使排烟风量与通风风量保持一致的方法。强调排烟工况下管网总阻力、漏风量均远大于通风空调工况，必须严格认真地计算。 【英文摘要】 Presents a method to make the smoke exhaust rate equal to the ventilation rate by smoke control zoning for the usage of the dual purpose fan. Emphasizes that the resistance of the pipe system and the air infiltration rate under smoke exhausting are far more than those under ventilation, so as to need a careful calculation. 【基金】 国家自然科学基金
