；厨房是一家餐厅的核心，而排油烟系统的核心就是风机，故风机对一家餐厅是极其重要的，但是，风机的品类非常多，我们该如何选择适合的风机给厨房排油烟呢？ People take food as the sky, so China ’s catering industry is very developed, but while we are enjoying the food, countless restaurants produce a large amount of oil fume. These oil fume are exhausted to the building's public flue or directly after purification. Discharge outdoors ; the kitchen is the core of a restaurant, and the core of the fume exhaust system is the fan. Therefore, the fan is extremely important for a restaurant. However, there are many types of fans. How do we choose a suitable fan to exhaust the kitchen with fume ? The following is an introduction by the kitchen exhaust fume expert "Green Island Wind".
：首先我们应该选型，选择合适风量的风机决定实际排烟效果，一般厨房应设置排油烟风机及补风机； I. Air volume selection : First of all, we should choose the type and select the appropriate air volume fan to determine the actual smoke exhaust effect. Generally, the kitchen should be equipped with exhaust fan and make-up fan;
1. Exhaust volume: Generally, the exhaust volume is calculated at 2000 air volume per meter of fume hood. In actual selection, the air volume should be appropriately enlarged or reduced according to the type of restaurant and the actual exhaust volume; meanwhile, the air volume should be considered in the pipeline. The loss during transportation, such as the pipeline is too long, the curve is particularly large, and the resistance in the public flue should be based on these factors, and then according to the manufacturer's parameter table (recommended to choose a regular well-known brand, the current parameter in the industry is more common) The most suitable air volume, so that the least money is spent, the smoke exhaust effect is guaranteed, and energy is saved;
2. Air supply volume: It is recommended to design the air supply volume according to 80% -90% of the exhaust air volume to ensure proper negative pressure in the kitchen and ensure that the smell of the kitchen does not spread to the dining room. At the same time, the negative pressure is controlled within 5pa to avoid the furnace from falling down. wind;
： Selection of fan type :
There are many types of fans, and the following factors should be considered in actual selection:
1. External motor: The fan for exhausting oil fume must use an external motor, so as to avoid oil fume from entering the motor and causing damage to the fan; as shown in the figure below, it can be seen that the motor is outside the fan;
2. Centrifugal type: Because a large suction power is required to exhaust the oil fume when exhausting the oil fume, there is a certain requirement on the pressure of the exhaust fan, so a centrifugal fan should be used; the centrifugal fans suitable for exhaust fume mainly have the following types:
① Cabinet-type centrifugal fan: Take the Green Island Wind DKT wind box as an example, with large air volume and low noise; it is suitable for places with high noise requirements and large smoke exhaust; (see the figure below)
② 11-62 centrifugal fan : Lvdaofeng 11-62 centrifugal fan has large air volume, high pressure, small volume and low cost; (see the figure below)
③ CF centrifugal fan : Lvdaofeng CF fan has high pressure, small size and low cost, and is suitable for restaurants with high pressure requirements; (see the figure below)
风11-62(E式)及13-48式也常见于排油烟系统； In addition, Green Island Wind 11-62 (E type) and 13-48 type are also common in fume exhaust systems;
Some small restaurants use axial flow fans due to cost considerations and short pipes, but axial flow pipe fans are easily damaged by oil fume corrosion, and have high noise and low pressure. They are not recommended; (see the figure below)
Third, the situation
1. When selecting a model, we must consider the situation on the site. Is it discharged through the public flue or discharged on the street? Corresponding measures: if it is discharged from the street, a centrifugal fan with large air volume and relatively low pressure (such as Lvdaofeng 11-62 centrifugal fan and wind cabinet) can be used; if it is discharged through a public flue and the restaurant uses the same flue When there are many, it is recommended to use a centrifugal fan with high pressure (such as Lvdaofeng CF fan);
2. Is the site installation location sufficient?
Corresponding measures: If the installation location is wide, you can choose a machine with a relatively large machine size to reduce noise and improve the comfort of the working environment of the kitchen staff; if the location is limited, use a machine with a smaller machine size and a higher speed and power;
3. How to choose the fan rotation direction?
Corresponding measures: As the centrifugal fan has left-handed and right-handed rotation, it is recommended to confirm the fan's rotation direction based on the site location (when the fan manufacturers leave the factory, most of the air outlets face upwards; that is, the default is 90 degrees right or 90 degrees left; facing the fan Suction port, the air outlet is to the right, that is, right-handed; facing toward the fan intake, the air outlet is to the left, that is, left-handed; the other rotation direction is divided into 0 degrees, 90 degrees, and 180 degrees, which can be adjusted by yourself)
Fourth, the owner's appeal
The owner's request is also a factor that must be considered in the design and selection. For example, if the owner requires low noise, it is recommended to use the Green Island Wind DKT series of centrifugal air cabinets ;
In summary, kitchen exhaust fume has a lot of attention to the choice of fan. At the same time, pay attention to the size of the pipeline, reasonable design, selection of fume purifiers, control box selection, and subsequent maintenance. These exhaust fume for a restaurant The effect plays a vital role. The above hopes to help you.
