在室内通风体系中，经常会使用到通风管道，在不同的建筑体系中需要的风管功能是不同的，因此使用到的风管类型也是不同的，比如通风管道与消防排烟管道在多个方面都存在着差异。那么通风管道与排烟管道有什么不同之处？各自的特点有哪些？如何区分呢？

　　In indoor ventilation systems, ventilation ducts are often used, and the required duct functions vary in different building systems, so the types of ducts used are also different. For example, there are differences between ventilation ducts and fire smoke exhaust ducts in multiple aspects. So what are the differences between ventilation ducts and smoke exhaust ducts? What are their respective characteristics? How to distinguish?

　　定义

　　通风管道：主要用于提供室内空气的流通和通风，以改善室内空气质量。通风管道的功能是通过自然通风或机械通风系统，将室外新鲜空气引入建筑物内部，同时将室内的污浊空气排出去，从而保持室内空气清新，有利于人们的健康。通风管道广泛应用于工业、建筑工程和城市基础建设中，是保证室内空气质量的重要设施。

　　Ventilation duct: mainly used to provide indoor air circulation and ventilation to improve indoor air quality. The function of ventilation ducts is to introduce fresh outdoor air into the interior of buildings through natural ventilation or mechanical ventilation systems, while discharging polluted indoor air, thereby maintaining fresh indoor air and promoting people's health. Ventilation ducts are widely used in industry, construction engineering, and urban infrastructure, and are important facilities for ensuring indoor air quality.

　　排烟管道：排除建筑物内部可能产生的烟雾和有毒气体，以保障人员生命安全和财产安全。排烟管道的功能是在火灾等紧急情况下，将烟雾和有毒气体快速排出建筑物，减少人员伤亡和财产损失，减少烟尘对建筑物结构和设备的腐蚀和损坏。

　　Smoke exhaust duct: to eliminate smoke and toxic gases that may be generated inside the building, in order to ensure the safety of personnel and property. The function of smoke exhaust pipes is to quickly exhaust smoke and toxic gases from buildings in emergency situations such as fires, reducing casualties and property damage, and minimizing the corrosion and damage of smoke and dust to building structures and equipment.

　　功能

　　通风管道：通风管道是工业与民用建筑的通风与空调工程用金属或复合管道，是为了使空气流通，降低有害气体浓度的一种工业及市政基础设施；通常应用于商业、办公、工业和住宅等建筑物中，以提供舒适的室内环境。通风管道的用途是通过良好的通风系统，调节室内温度和湿度，排除有害气体和异味，保持室内空气清新。此外，通风管道通常使用阻燃材料制造，具备一定的防火功能。

　　Ventilation duct: A ventilation duct is a metal or composite duct used for ventilation and air conditioning engineering in industrial and civil buildings. It is an industrial and municipal infrastructure designed to circulate air and reduce the concentration of harmful gases; Usually used in commercial, office, industrial, and residential buildings to provide a comfortable indoor environment. The purpose of ventilation ducts is to regulate indoor temperature and humidity, eliminate harmful gases and odors, and maintain fresh indoor air through a good ventilation system. In addition, ventilation ducts are usually made of flame-retardant materials, which have certain fire prevention functions.

　　排烟管道：排烟管道是为了避免设施在生产的时候产生的有害物质，对车间的空气造成污染，它通常都是从排风扇或吸风口将有害的物体收集，再通过管道送到净化设备处理，达到标准之后才能够排放或者是再利用；为了减少排风机的噪音对周围环境的影响，排烟管道上还会设置消音器。此外排烟管道上通常会设置排烟防火阀，在高层建筑、地下车库、酒店、餐厅、医院等场所的消防安全系统中，其主要用途是在火灾发生时，排除烟雾和有毒气体，确保人员安全疏散和消防人员的救援工作。

　　Smoke exhaust duct: Smoke exhaust ducts are designed to prevent harmful substances generated by facilities during production from polluting the air in the workshop. They usually collect harmful objects from exhaust fans or suction ports, and then send them to purification equipment for treatment through the duct. Only after meeting standards can they be discharged or reused; In order to reduce the impact of exhaust fan noise on the surrounding environment, silencers will also be installed on the smoke exhaust ducts. In addition, smoke exhaust fire dampers are usually installed on smoke exhaust ducts. In the fire safety systems of high-rise buildings, underground garages, hotels, restaurants, hospitals and other places, their main purpose is to eliminate smoke and toxic gases in the event of a fire, ensuring the safe evacuation of personnel and the rescue work of firefighters.
