What problems will occur in the configuration of axial flow fan

The purpose of using forced draft fans in many places is to achieve the effect of ventilation, and to achieve this effect in places, forced draft fans play an irreplaceable role. However, whether the effect of the axial flow fan can be brought into full play depends on the configuration of the axial flow fan. The configuration of the fan will directly affect the use of the axial flow fan. Therefore, this problem must attract the attention of users? BR.

The power consumption of the forced draft fan with excessive air volume will also increase, and the noise will also increase. Therefore, the wind speed on the windward side is generally 35m/s. In addition, the noise should be considered when configuring the fan. At present, the axial flow fan with large diameter, low speed, and small blade twist angle is generally selected to reduce the fan noise.

The energy regulation mode, frequency conversion speed regulation and slide valve stepless regulation belong to stepless regulation. Stepless regulation has the advantages of energy saving, low noise and vibration, good starting performance and low interference to the power supply system. At present, the commonly used energy regulation methods in air-cooled heat pump units include compressor number control, compressor clearance operation, cylinder unloading regulation (piston type), variable frequency speed regulation (scroll type), slide valve stepless regulation (screw type). From the energy regulation methods, we can see that the number control, fmdw 110818 addjgvldo compressor clearance operation, and cylinder unloading regulation are all classified into staged regulation.

In addition, the wind speed on the windward side of the condenser needs to be greatly guaranteed, because this is related to the frosting speed of the air side heat exchanger during winter operation. The higher the wind speed on the windward side, the less likely it is to frost during winter operation.

In view of the above aspects, if users can do as much as possible, the configuration of axial flow fan can be guaranteed to a large extent, and its role will also improve with the improvement of configuration, so this aspect is also worthy of careful treatment by users.
