Introduction of Sawtooth-shaped Roof Greenhouse
The greenhouse with sawtooth-shaped windows at the top is a specially designed agricultural greenhouse. Its roof features a continuous sawtooth structure (resembling waves or triangles), and there are openable and closable ventilation windows installed at the top or on the sides of each sawtooth. This design forms a natural ventilation channel through the alternating height differences of the sawteeth. In combination with the window opening system, it achieves efficient air circulation and temperature regulation inside and outside the greenhouse.
Features
Excellent ventilation performance: The sawtooth-shaped roof, combined with the openable windows, makes use of the principle of hot air rising to create a stable "chimney effect", rapidly expelling hot and humid air and lowering the temperature inside the greenhouse.
Uniform light distribution: The angle of the sawteeth can optimize the incident direction of sunlight, reducing shadow obstruction and ensuring that crops receive light evenly.
Strong resistance to wind and rain: The sawtooth structure disperses the wind load. Paired with large-diameter hot-dip galvanized columns, it has high stability and is suitable for areas with frequent wind and rain.
Energy conservation and environmental protection: By relying on natural ventilation for cooling, it reduces the energy consumption requirements of mechanical equipment.
Flexible control: The windows can be controlled manually or automatically to adapt to different weather conditions (for example, they can be closed during heavy rain to prevent water from entering).
Rainwater collection function: Equipped with drainage gutters, it can collect and store rainwater during the rainy season for use in the dry season, achieving efficient utilization of water resources and reducing irrigation costs.
Applicable Climate Types
High-temperature and High-humidity Climates: For example, in tropical and subtropical regions, humidity and temperature are reduced through ventilation to prevent crops from getting moldy.
Areas with Abundant Rainfall: The sawtooth design allows for rapid drainage. The combination of insect-proof netting and agricultural film prevents the accumulation of rainwater and pest damage. Meanwhile, the drainage gutters can collect rainwater for use during the dry season.
Areas with Strong Winds: The wind-resistant structural design (such as the hot-dip galvanized steel pipe frame) ensures stability.
Regions with a Large Temperature Difference between Day and Night: Open the windows during the day to dissipate heat and close them at night to keep the heat in, maintaining an appropriate temperature for the growth of crops.
Areas with Seasonal Drought: The rainwater collection system can store water resources during the rainy season, relieving the irrigation pressure during the dry season.
Typical Application Scenarios: Coastal areas with strong winds, areas with seasonal drought, regions with both rainy and dry seasons, tropical areas with high temperatures, etc.
