For greenhouse cooling, cooling pad and exhaust fan are the first choice. We make reasonable selection according to the cooling system of cooling pad and exhaust fan.
The cooling system of cooling pad fan generally adopts negative pressure longitudinal ventilation. In the greenhouse, the distance between the fan and the cooling pad is preferably 30-70m, and the channel resistance is about 25-40Pa. The fan must be selected to meet the ventilation volume required under the static pressure of 25.4Pa. The fan selected for the cooling pads exhaust fan cooling system is a low-pressure large flow axial flow energy-saving fan.
When selecting the cooling pad exhaust fan for greenhouse cooling, customers should pay more attention to the installation, because the reasonable installation, which can significantly improve the cooling effect.
The exhaust fan is generally arranged on the gable at one side of the greenhouse, and cooling pad is usually arranged on the gable at the other side.
