Greenhouses Ventilation System Detail
Natural ventilation of single tunnel greenhouse including Plastic film tunnel greenhouses, solar tunnel greenhouses, etc. belong to single tunnel greenhouses. Single greenhouses have natural ventilation systems. The type of vents in a single greenhouse mainly depends on the type of greenhouse covering material. The plastic film is rolled up to form a ventilation window.
In order to obtain a larger ventilation window area, the natural ventilation of the multi-span greenhouse mostly adopts a joint structure for the side windows and roof ventilation. The location and opening direction of the ventilation windows depend on the greenhouse roof structure and the local wind direction. The opening and closing mode of the side windows and roof is mainly determined by factors such as the type of greenhouse covering materials, the degree of greenhouse automation requirements, and the cost of greenhouse construction.
The Venlo roof greenhouse is usually covered with glass or polycarbonate hollow board materials. The Venlo greenhouse is the most typical Venlo roof greenhouse. The side windows of the greenhouse can be top-hung or sliding windows, and the top windows can be top-hung full-length windows or top-hung segmented windows. The full-opening roof window is the latest greenhouse style. The natural ventilation airflow mode is side window air intake and top window air outlet.
The roof of the dome film greenhouse is an arched circle type, usually composed of two semicircular arcs, and the covering material is a plastic film. The greenhouse ventilation window is generally a full-length opening, with roll film opening windows and top hanging windows.
