通风系统可以实现屋内和屋外的通风了，屋里和屋外的空气就可以得到很好的流通，可以帮助空气进行一个很好的互换的阶段。通风设备该如何设计安装呢？
The ventilation system can be ventilated in the house and outside the house, and the air in the room and outside can be well circulated, which can help the air carry on a very good interchangeability phase. How should the ventilation equipment be designed and installed?
1．送、排风口的距离要适当
The distance between the and the exhaust ports should be appropriate
排风口与送风口少保持3米的距离以防气流短路
At least 3 meters away from the air outlet to prevent air flow short circuit.
2．选用合适的风阀 choose the appropriate wind valve
从原则上讲，系统风压平衡的误差在10％－15％以内，可以不设调节阀，但实际上仅靠调风管尺寸来调风压是很困难的，所以，要设风量调节阀进行调节。
In principle, the system wind pressure balance error is within 10% - 15%, can not set the regulating valve, but in fact, it is very difficult to adjust the wind pressure only by the size of the wind regulating tube, so we should adjust the air volume regulating valve.
风管分支处应设风量调节阀。在三通分支处可设三通调节阀，或在分支处设调节阀。
In the branch of the wind pipe, the air volume regulating valve should be set. A three way regulating valve can be set at three branches, or a regulating valve is arranged at the branch.
明显不利的环路可以不设调节阀，以减少阻力损失。
The obvious disadvantage of the loop can be no control valve to reduce resistance loss.
在需防火阀处可用防火调节阀替代调节阀
The fire control valve can be used instead of the regulating valve at the fire damper.
送风口处的百叶风口宜用带调节阀的送风口，要求不高的可采用双层百叶风口，用调节风口角度调节风量。
The blinds at the outlet of the air outlet should be provided with an air inlet with a regulating valve. A double louver outlet can be used if the requirements are not high, and the air volume can be adjusted by adjusting the air inlet angle.
新风进口处宜装设可严密开关的风阀，严寒地区应装设保温风阀，有自动控制时，应采用电动风阀。
Hot air inlet valve should be installed at the inlet of fresh air, and the insulation air valve should be installed in the cold area. When the automatic control is applied, the electric air valve should be used.
3．风管的布置 The arrangement of wind pipes
要尽量减少局部阻力，即减少弯管、三通、变径的数量
To minimize local resistance, that is to reduce the number of elbow, three, and variable diameters.
弯管的中心曲率半径不要小于其风管直径或边长，一般可用1.25倍直径或边长
The center curvature radius of the elbow should not be less than the diameter or length of the duct. It can generally be used 1.25 times the diameter or side length.
为便于风管系统的调节，在干管分支点前后，应预留测压孔。测压孔距前面的局部管件的距离应大于5b(b为矩形风管的长边或圆形风管的直径)，距后面的局部管件的距离应不小于2b。通风机出口处气流较稳定的管段上宜应预留测压孔。
In order to facilitate the regulation of the air duct system, the pressure hole should be reserved before and after the branch point of the trunk. The distance from the local tube to the front of the pressure measuring hole should be greater than 5B (B is the diameter of the long or circular duct of the rectangular duct), and the distance from the local pipe to the rear should not be less than 2B. The pressure hole should be reserved for the stable pipe section at the outlet of the fan.
4．新风进口位置 new wind import position
进风口宜设在室外空气比较洁净的地方，保证空气质量
The inlet should be located in a cleaner outdoor air to ensure air quality.
宜设在北墙上，避免设在屋顶和西墙上，并宜设在建筑物的背阴处这样可以使夏季吸入的室外空气温度低一些
It should be located on the north wall to avoid being located on the roof and west wall, and should be located at the shady side of the building so that the outdoor air temperature in summer can be reduced.
进风口底部距室外地面不宜小于两米，当进风口布置在绿化地带时，则不宜小于一米
The distance between the bottom of the intake and the outdoor floor should not be less than two meters. When the air inlet is arranged in the greening zone, it should not be less than one meter.
应尽量布置在排风口的上风侧，且低于排风口，并尽量保持不小于10米的间距
As far as possible, the upper side of the exhaust port should be placed below the outlet, and the spacing should be kept as low as 10 meters.
5．新风口的要求 the requirements of the new tuyere
宜采用固定百叶窗
It is advisable to use a fixed shutter
多雨地区宜采用防水百叶窗以防雨水进入
Waterproof louvers should be used in rainy areas to prevent rain from entering.
为防止鸟类进入，百叶窗内宜设金属网
In order to prevent birds from entering, it is advisable to set metal mesh in louvers.
6．排风管的新做法 New practice of 6. row air duct
类似酒店客房的排风系统设计可如下考虑：利用排气扇将室内风排到走廊的吊顶内,在走廊设排风管排风,为有效利用余热,排风机可设置于卫生间。
The design of the ventilation system for similar hotel rooms can be considered as follows: using the exhaust fan to drain the indoor air into the ceiling of the corridor and exhaust the wind pipe in the corridor, in order to use the residual heat effectively, the exhaust fan can be set in the toilet.
