Currently, the gradual adoption of automatic ventilation fans has played a crucial role in the growth of vegetables. Do you know the ventilation principle of greenhouse intelligent ventilation fans? Let's take a look at the following content:

The intelligent greenhouse exhaust fan can draw out some indoor air, causing the indoor air pressure to be less than atmospheric pressure or below normal levels. At this point, there is an intake port on the opposite side of the intelligent greenhouse ventilation fan, where external air enters the space under atmospheric pressure automatically. Consequently, a directional and stable airflow band is formed within the space. This type of ventilation is commonly referred to as negative pressure ventilation. The characteristics of negative pressure ventilation include directional and stable airflow, connecting with the outside rather than circulating within the space. If a cooling water curtain is installed on the opposite side of the intelligent greenhouse ventilation fan, the external air exchanges heat with the water as it passes through the wet curtain, resulting in a temperature drop and achieving the goal of cooling the greenhouse.

Testing Method for Automatic Ventilation Fan

When connecting power, prevent the loss of single-phase power. If one phase of power is missing, the motor may burn out.

2. The main drive components (such as reducers, transmission bearings, etc.) should be lubricated annually, and the gearboxes should be filled with antifreeze oil.

During installation, ensure that the length (tightness) of the roller cord is adjusted uniformly to keep the rolled-up bamboo curtains in a straight line. During use, frequently adjust the roller cord. Uneven cord length or inconsistent tightness of the bamboo curtains can result in curved shapes, increasing the torque force on the smart fan and roller, which may affect performance or damage the fan and roller.

4. The bottom of the bamboo mat (where it connects to the roller) should not be overly wet, as it makes the mat too heavy and difficult to roll up. When in use, cover the bamboo mat with plastic sheeting to prevent moisture from rain and snow, and it also facilitates snow removal.

5. Parts are coated with anti-rust paint annually.
