Ventilation system
The window ventilation system for industrial greenhouses is designed for natural air exchange between the closed volume of the greenhouse and outside air through ventilation openings in the roof section of the translucent enclosure for 4th generation plants.
Opening is automatic and remote. The casement ties are connected to a galvanized tube that slides in clamps along the top rail of the truss. The designs primarily use drives, gearboxes, and chain clutches from RIDDER (Netherlands) or our own production.
The total area of the greenhouse roof ventilation openings is up to 24% of the greenhouse's area. The opening angle of the vents is 41°. This ventilation opening area allows for the supply of the required volume of outside air into the greenhouses to maintain optimal temperature parameters during periods of excessive solar insolation.
The greenhouse's drive-operated vent opening and closing mechanism allows for simultaneous opening and lowering of vents across the entire area of each climate zone, which is assigned to ensure uniform microclimate parameters within a controlled volume. The vent opening system is a rack-and-pinion push-pull system.
The system is fully adapted to standard roofing, made possible by the development of new profiles and vents. This allows for easy installation of cassette-type mosquito nets with various mesh sizes.
The holder is designed as a box, which protects the mosquito net from precipitation and weather conditions when the vent is closed. A new ridge bar has been developed to ensure proper operation of the vents and to adapt to the existing roof.
The use of mosquito nets on the vents of production greenhouses—vegetable, seedling, flower, biogreenhouses, and others—prevents flying insect pests from entering the growing space occupied by the plant community. During the summer, pest populations, particularly whiteflies and aphids, can develop on wild plants. Their entry into greenhouses causes significant damage to cultivated plants, reducing their productivity and marketable yield.
Installing mosquito nets on the vents of greenhouses in industrial biolaboratories that use breeding populations of harmful flying and crawling insects and mites in the production process prevents them from entering the bio-greenhouses through the vents onto the territory of greenhouse enterprises and further into the production greenhouses.
Mosquito nets are also extremely effective on the vents of research, breeding, and demonstration greenhouses, where the production process, due to the specifics of production, must be reliably isolated from the surrounding environment to prevent flying insects from entering or leaving the greenhouses.
Equipping industrial greenhouses with specially designed vents that allow for the installation of cassette-type mosquito nets is a reliable means of protecting plants from harmful flying insects in open ground and isolating the environment from similar pathogenic sources that are a product of technological processes in greenhouses.
