Selection method:
1. Calculate the amount of air delivery: According to the ventilation calculation, determine the required air supply volume.This usually includes the calculation of air volume calculation and air gas replacement.The air volume is usually calculated in volume flow or standard volume flow, and the unit is M3/H or M3/S.At the same time, the number of air replacement needs to be considered, that is, the frequency of the air in the room during the unit time and outdoor air is usually 6-12 times/hour.
2. Evaluation pressure: When choosing a bleach, you also need to evaluate the pressure required by the fan.This can be completed through a variety of channels. Detailed calculation before the measured measurement is performed to determine the air duct resistance required and caused the pressure drop.Factors that need to be considered include external pressure, pipeline resistance, diversion, and resistance of mixed gases, and to make up for the effects of outdoor wind pressure and vertical ventilation.
3. Consider the conveying volume and conveying pressure of the gas or liquid: According to the production or operating needs, select the model and parameters of the mixed fan to ensure that it can meet the needs of the gas or liquid transportation and pressure of the required gas.
4. Consider the requirements of environmental noise: According to the noise restrictions of the workplace, choose a low -noise and lightweight bleach, and take measures such as noise reduction equipment and sound insulation materials to reduce noise interference.
5. Consider the installation space and environment: The mixed ventilator needs to be installed in a relatively stable environment, and a bracket and shock absorption measures are set in key parts to ensure stable and safe operation.At the same time, the size and shape of the installation space should be considered to ensure that the fan can be installed and running normally.
6. Considering the reliability and operating cost of equipment: Selecting and reliable and stable flow fans can reduce operating shutdown rate and maintenance costs, and save energy overhead.
7. Consider the reliability and safety of the applicable environment: You need to choose a mixed fans that meet the environmental safety norms, and perform strict quality testing and trial operation before installation to ensure that it can operate within the expected safety range.
By following the above selection methods, it can ensure the efficient and stable operation of the blealing fan, and meet actual needs.
The above is the selection of a mixed fans
