In major farming industries, the use of fan equipment will change the indoor environment. For example, the indoor environment of cattle and sheep breeding will have a lot of odors. In summer, it can not only increase the indoor temperature, but also change the airflow in the environment and purify the odor.

In recent years, in the practical engineering application of animal husbandry fans, for the variable speed use of speed regulating fans, the application of voltage regulation and variable speed of single-phase asynchronous motors has gradually changed to the application of variable frequency speed regulation of three-phase asynchronous motors.

The material of air supply duct, glass fiber reinforced plastic and plastic air duct is generally galvanized sheet, and can also be used

It is more important in the debugging process, and the number of people participating in the debugging of the cooling fan is not less than two. One person needs to control the power supply of the cooling fan, and the other person needs to observe the operation of the cooling fan
