油烟净化的目的是为了排放，因此严格地说，选择风机的目的就是要确保风量的排放。工程现场中风机的选择是个，存在很多误区。
The purpose of lampblack purification is to discharge, so strictly speaking, the purpose of fan selection is to ensure the discharge of air volume. The selection of wind turbine in the project site is a key point, and there are many misunderstandings.
风机的作用就是要把经过油烟净化器净化后的烟气排到室外去，但是要保证风量，先要确保风机的压力能够克服通风系统的阻力，否则无论风机标多少风量，*终都达不到理想的抽风效果。选择风机时,光是看风机的风量是不够的。
The function of the fan is to discharge the smoke purified by the lampblack purifier to the outside, but to ensure the air volume, first ensure that the pressure of the fan can overcome the resistance of the ventilation system, otherwise, no matter how much air volume the fan is marked, * will not achieve the ideal ventilation effect. When selecting a fan, it is not enough to just look at the air volume of the fan.
典型的风机参数图如下：
Typical fan parameter diagram is as follows:
可知，不同的风机特性位于坐标不同的位置，使用者根据厨房炉头的数量确定风量的大小，然后再根据管道的大小确定风速（厨房排烟管道的风速一般选择在10-13米/秒），再由风速根据管道的长度、弯头的数量、净化器的阻力，算出推算系统的总阻力，然后从“Y”坐标选择风机的全压，再从“X”坐标选择风量参数，两条线的交错点附近确定一条风机曲线，对应一个风机型号，这个就是适合的风机。
It can be seen that different fan characteristics are located at different locations in different coordinates. The user determines the air volume according to the number of kitchen burners, and then determines the wind speed according to the size of the duct (the wind speed of kitchen smoke exhaust duct is generally 10-13 m/s). Then, the total resistance of the system is calculated according to the length of the duct, the number of elbows, and the resistance of the purifier. Then, the full pressure of the fan is selected from the "Y" coordinate, Then select the air volume parameter from the "X" coordinate, and determine a fan curve near the intersection point of the two lines, corresponding to a fan model, which is the appropriate fan.
那么如何确定系统的阻力呢？按照理论计算比较复杂，简单的经验依据就是：
So how to determine the resistance of the system? The theoretical calculation is relatively complicated, and the simple empirical basis is:
直管压损：5pa/米
Pressure loss of straight pipe: 5pa/m
弯头或变径压损：30pa/个
Pressure loss of elbow or reducer: 30pa/piece
静电油烟净化器压损：200pa/台
Pressure loss of electrostatic lampblack purifier: 200pa/set
烟罩的抽风口压损：200pa/个
Pressure loss at exhaust port of smoke hood: 200pa/piece
炉头数：8个
Number of furnace heads: 8
如果20米风管，弯头变径5个，加上烟罩的压损200pa和科蓝油烟净化器的压损200pa，保持动压200pa，总压损耗约为：
If 20 meters of air duct, 5 elbows are reduced, the pressure loss of smoke hood is 200pa, and the pressure loss of Kelan oil smoke purifier is 200pa, the dynamic pressure is maintained at 200pa, and the total pressure loss is about:
20*5+5*30+200+200+200=850pa，取风机的压力为1000pa。
20 * 5+5 * 30+200+200+200=850pa, and the pressure of the intake fan is 1000pa.
8个炉头风量为1600立方米，取风机的风量为1800立方米。
The air volume of 8 burners is 1600 m3, and the air volume of air intake fan is 1800 m3.
那么根据的纵横坐标，可选6.3H和5.6H（两者的性能有重叠部分）。假设选用6.3H，再看，根据全压和风量，选择800转比较合适。
According to the vertical and horizontal coordinates of, 6.3H and 5.6H can be selected (their performance overlaps). Assuming 6.3H is selected, 800 rpm is appropriate according to the total pressure and air volume.
看重油烟净化,当代餐饮厨房都少不了油烟净化器,具高品质的油烟净化器,采取适宜的圆筒蜂巢电场,净化效用高达98%,
Pay attention to oil smoke purification. Modern catering kitchens can't do without oil smoke purifiers. They are equipped with high quality oil smoke purifiers. With appropriate cylindrical honeycomb electric fields, the purification effect is up to 98%,
