There are methods to reduce the temperature in summer, the most common and at the same time the cheapest of which is the pad and fan method.Therefore, in humid areas, because the air has high humidity, evaporation is difficult. How to run this system is that cellulose pads are installed on one side of the greenhouse and suction fans are located on the opposite side.
This distance should not be more than 45 and less than 35 meters. With the circulation of the fans, hot air from outside the greenhouse penetrates into the pads and while passing through the pads, it loses its temperature and flows in the greenhouse space to leave the fans.
