产品使用状况说明：

在地铁、公路隧道、铁路隧道等基础工程建设中，其空气质量标准、安全因素靠风机强制通排风机达到要求。就通风系统而言，

要长期保持良好的空气质量，否则对人体有害，如图说明。

一氧化碳对人体危害程度说明：

车辆连续的穿过隧道，使有毒气体不断增多，隧道内自然空气如不及时充分交换，必然导致对人体的危害（详见对人体影响危害

时间的曲线图）。因此，必须通过强制通风，将足够的新鲜空气输入隧道内，同事排除有害气体。

总之，地铁、铁路、公路隧道通风使用该风机，主要为降低CO的含量到允许值，以防止汽（柴）油发动机的废气污染，如 NO、

NO 、NO 。在紧急状态下，必须按要求控制烟雾排放，目前国际普遍采用WHO世界卫生组织的推荐值，即NO 替代原CO值作为通2 3 2

风控制的主要参数，同时还要保证车辆行驶的能见度和保证隧道内人员的逃避路径。所以，隧道通风系统必须保证事故状态下车辆和

人员的安全。YFTNV/YFTNV(R) 系列射流风机其安全可靠性、正反转、耐高温等特点均考虑了这一方面，特别在耐高温方面，该系

列射流风机已通过国家消防试验检测合格，可耐高温280℃/1h（高于国家标准250℃/1h），并取得了公安部消防产品合格评定中心颁

发的3C认证证书。产品出厂前，对风机进行全性能试验，以确保产品质量。

隧道通风系统设计和产品选型依据：

1、交通隧道原则上可分为三类：即地铁、公路隧道、铁路隧道。

2、常规运行及紧急状态下运行安全性、可靠性的先决条件是安装确保各系统之间协调并充分发挥作用的环控系统。

A 机械系统：通风、消防、排污 B 动力系统：供电、输配电、警急电力

C 灯光系统：通灯照明、局部照明、荧光指示 D 通信系统：电话、无线电、计算机终端

E 交通系统：灯光、信号、标志、监视控制系统：交通状况和设备运行状况的监控 F

3、隧道通风系统可以有如下三种基本方式或可采取混合方式。

① 纵向通风系统：这是最基本的通风方式。新风气流从隧道入口端流向出口端，沿隧道纵向无需安装通风管道。该通风方式一般

选用可逆转射流风机。将风机安装在隧道顶部或侧面，可两个方向全面通风，以达到双向通风或控制烟雾；若隧道较长则必须

加中央送、排风竖井，竖井与大气相联，组成混合通风方式。

② 全横向通风系统：沿隧道方向设置送、排风道，新风集中从风亭采集，排风集中从风塔排除，一般将送风道设置在路面以下，排

风道设置在车道上部，送风道与排风道每隔一定间距设有送、排风口，在事故工况下沿隧道横断面及时排风，由此抽出烟雾。

③ 半横向通风系统：该系统又可区分为送风型半横向通风方式和排风型半横向通风方式，一般采用排风型半横向通风方式，新风

从洞口进入，排风相似全横向通风系统。

4、隧道通风应考虑的因素：

A 工程投资 B 电力容量 C 运行费用

D 空气质量 E 安全因素 F 紧急状态下的保证措施

上述因素经综合后确立最优化方案

5、隧道通风系统通风机数量、机号选择的因素：

A CO、NOx及烟雾浓度 B 车流量（车辆密度、时速）

C 风力负荷（隧道长×宽×高） D 废气排放（车龄、数量）

E 发生火警时的应急措施

6、隧道通风系统推力计算理论依据

① 隧道通风系统推力计算依据

●入口出口阻力损失

●隧道表面及设备等摩擦系数

●车辆摩擦系数（在最劣势的条件下计算车辆运动或活塞风效应）

●最劣势条件下洞外风速对出、入口的影响

●隧道地形、位置（坡度、海拔）

●发生火警时所需的推力（温度、压力、时间）

② 隧道压降（Pa）理论转换为射流风机所需的推力（N）

●射流式通风机的推力是风机进口与出口的动量变化，即风机推力为：

Ns=C1×质量流量×气流速度（N）

式中：Ns=(LSO)N值

C1=经验修正系数

质量流量=空气密度×体积流量

●隧道中使用的射流风机与隧道内气流之间的相对速度、隧道内摩擦系数和同组平行布置影响有关，所以，射流风机

的有效推力为：

Ne=Ns×(1-Vt/Vj)C2×C3

式中：Ne=风机有效推力（N）

Vt=隧道内风速（m/s）

Vj =射流速度（m/s）

C2=隧道内摩擦系数

C3=同组平行布置流向损失

（该损失如风机机组之间相隔风机直径100倍，使射流速度不影响顺气流方向的运行条件可以不考虑）。

Applications:

The air quality and safety inside the metro and tunnel projects rely on the ventilation system. The chart above illustrates the effects of carbon

monoxide on the human body.

How Carbon Monoxide affects the human body:

A constant stream of cars running in the tunnel leads to an accumulation of poisonous gases. If not exchanged with fresh natural air, they will have

harmful effects on health (the chart above shows it in detail). So it is important to send in enough clean air into the tunnel and exhaust the poisonous

gases.

YFTNV/YFTNV(R) fans can be used in the metro, railway and tunnel projects to reduce the CO concentration to the allowable level and prevent the

exhaust pollutions, such as NO, NO2 and NO3. According to the recommendations from the WHO, the amount of Nitrogen oxides (NO2) has

become the indicator in measuring the efficiency of the ventilation system. Minimum visibility is also required inside the tunnel. Emergency exits

have to be well indicated and visible. Thus, the tunnel ventilation system is required to ensure safety in the event of fire or other accidents.

YFTNV/YFTNV(R) fans fit in with the features of reliability, forward and reverse rotations and high temperature resistance. The fans have been

tested and certified to run 1 hour under 280°C (above the national standard of 250°C / 1h) . CCCf (China Compulsory Certification for Fire-fighting

Products) certificate issued by China Certification Centre for Fire Products Ministry of Public Security has also been obtained. Tests have been

performed on fans to ensure their optimum performance before leaving the factory.

1. Tunnels can be categorized into metro, road tunnel and rail tunnel.

2. Reliability and safety under both normal and emergency conditions are vitally important to the tunnel ventilation system. But first a comprehensive environmental control system shall be established to ensure that all subsystems coordinate well and function properly. A. Mechanical System: ventilation, fire protection and drainage B. Power System: power supply, power transmission and distribution and emergency power C. Lighting System: all-area lighting, local lighting and fluorescent indicator D. Communication System: phone, radio and computer terminal E. Transport System: light, signal, sign and monitoring F. Control System: traffic status and equipment status

3. In designing tunnel ventilation system, there are three forms of systems to choose from: I. Longitudinal ventilation system: This is the basic form. The fresh air flows through the tunnel, requiring no ducts. Reversible jet fans are generally used here, mounted at the top or sides of the tunnel for bi-directional ventilation. For a long tunnel, there also shall be vertical shafts for ventilation. II. Transverse ventilation system: Along the tunnel are set up supply ducts that generally are located under the roadway and exhaust ducts that generally are located above the lanes. Fresh air is collected from the ventilation pavilion and air is exhausted through the ventilation tower. Both the supply inlets and exhaust outlets are spaced for exhausting smoke timely. III. Semi- transverse ventilation system: This system can be classified into semi-transverse supply method and semi- transverse exhaust method which is the mainly adopted method. The fresh air is pumped into the tunnel through adits. The way air is exhausted is similar to transverse ventilation system.

4. Factors to be considered in tunnel ventilation:

A) Financial investment B) Power Capacity C) Operational costsD) Air Quality E) Safety factors F) Emergency procedures

5. Factors to be considered in determining the number and size of fans: A) The density of CO, NOx and smoke B) Traffic volume and speedC) Wind load (tunnel width by length by height) D) Vehicular exhaust (number and age of vehicles) E ) Emergency procedures in the event of fire

6. Calculations of thrust required in the tunnel ventilation system: 1. Factors to be considered for thrust calculation:

● Resistance loss at the outlet and inlet

● Friction factor of tunnel surface and equipment

● Friction factor of vehicles (piston effect to be considered under the extreme conditions)

● Airflow velocity outside the entrance/exit under the extreme conditions

● Geographic location of the tunnel(altitude, slope)

● Thrust required in the event of fire (temperature, pressure, time)

2 . Conversion of tunnel pressure drop (Pa) into the thrust required for the jet fan:

● The thrust required for the jet fan is the rate of change of momentum:

Ns=C1 X mass flow X airflow velocity Where, Ns=(LSO)N C1= Empirical correction factor Mass flow= Air Density X Volume

● The thrust is related to the relative airflow velocity, friction factor and layout of fans. Therefore, the effective thrust of the jet fan is:

Ne=Ns X (1-Vt/Vj)C2 X C3 Where, Ne=Fan’s effective thrust (N) Vt=Airflow velocity inside the tunnel (m/s) Vj=Jet Velocity (m/s) C2=Friction factor inside the tunnel C3=Airflow loss due to layout of fans

(This loss can be ignored if the fans are spaced at a minimum of 100 times of the fan diameter in order for the jet velocity not to affect the performance of fans mounted downstream).
