通风、空调系统类管道纵横交错贯穿于现代化建筑物中,成为建筑火灾蔓延的主要途径之一,由其导致的火灾蔓延后果极为严重。同时,通风系统又是燃烧爆炸危险场所的重要防范设施,通风换气是防止可燃气体、粉尘等发生积聚并燃烧爆炸的手段之一,也是保证建筑人员健康安全的手段。《建筑设计防火规范》(GB 50016-2014,以下简称GB 50016)对暖通空调工程防火设计与施工要求进行了规定。广义讲,建筑防排烟系统也属于暖通工程的一部分,在《通风与空调工程施工质量验收规范》(GB50243)将送风、排风、防排烟、除尘和气力输送系统工程均作为通风系统。而GB 50016将有
Ventilation, air-conditioning system tubes criss-crossing in the modern buildings, as the construction of fire one of the main ways to spread the fire caused by the spread of the consequences of extremely serious. At the same time, the ventilation system is an important precautionary measure for burning dangerous place of explosion. Ventilation is one way to prevent combustible gas and dust from buildup and explode. It is also a means to ensure the health and safety of construction personnel. The Code for Fire Prevention of Building Design (GB 50016-2014, hereinafter referred to as GB 50016) stipulates the fire protection design and construction requirements of HVAC works. In a broad sense, the building smoke control system is also part of the HVAC project. Ventilation, exhaust ventilation, smoke control, dust removal and pneumatic conveying systems are all ventilated in the “Code for Construction Quality Acceptance of Ventilation and Air Conditioning Engineering” (GB50243) system. And GB 50016 will have
