The prod Multi-span greenhouse introduction uction cost of the film multi-span greenhouse is relatively low, and it is an economical greenhouse, which is suitable for most parts of my country. In northern regions, double-film greenhouses are mostly used, and single-film greenhouses are mostly used in southern regions. After the double-layer membrane is inflated, a thick air bag can be formed, which can effectively prevent heat loss and prevent the intrusion of cold air, with good thermal insulation effect and low operating cost in winter. The top of the covering material is covered with polyethylene non-drip longevity film, the outer layer is anti-ultraviolet, and the inner layer is anti-condensation; the surrounding can be covered with polyethylene non-drip longevity film or polycarbonate hollow board according to user needs.
Film multi-span greenhouse can be equipped with internal and external shading system, fan water curtain forced cooling system, internal thermal insulation system, heating equipment, spray or sprinkler irrigation equipment, pure water treatment equipment and intelligent control system according to the requirements of users.
1. Shade inside and outside the multi-span greenhouse: use the transmission mechanism to push and pull the switch of the shading net. In summer, the inner and outer shading is turned on. The outer shading can filter out most of the strong light so that the plants in the shed are not burned, and the inner shading can evenly scatter the light through diffuse reflection.
2. Film multi-span greenhouse fan water curtain: The negative pressure is formed by the fan sucking air outward, forcing the airflow to pass through the water curtain to cool down and enter the greenhouse, thus playing a role in cooling. In the hot summer, the outdoor temperature is thirty-five or six degrees, and it can quickly drop to twenty-six or seven degrees after cooling through the wet curtain.
