      According to relevant persons, the main principles for the use of variable frequency fans are as follows:
      1. Reasonable design and layout are the basis for the use of variable frequency fans. Generally, the smaller ventilation fan units are designed as variable frequency fan units.
      2. The premise of the need to be equipped with a relatively environmental controller is that it can be adjusted automatically or step by step through instructions to avoid the cumbersome and lag caused by manual operation.
      3. Understand the type, number and operating parameters of each environmental control device on site. Easy to control accurately.
      4. Be familiar with the ventilation goals required for the house.
      5. Before using the variable frequency fan, the equipment parameters must be measured in advance. The efficiency of different frequencies, the negative pressure that should be achieved after the corresponding number of dampers and small windows reach the required opening, etc.
