One of the characteristics of modern agricultural development is the high efficiency of the greenhouse, but the greenhouse is a closed planting mode, it needs the help of auxiliary tools to achieve the greenhouse ventilation, moisture-proof and odor proof, the auxiliary tool is dutch fan.
The air convection inside and outside the greenhouse is realized by using the fan to adjust the humidity and temperature in the greenhouse.
The dutch fans in the greenhouse are generally installed in the middle of the south facade of the multi span greenhouse. The number of dutch fans can be determined according to the area of the greenhouse. Basically, it is ideal that the ventilation rate in the greenhouse can reach about 60 times an hour.
