The greenhouse external shading system is a shading device installed on the exterior roof of a greenhouse, primarily used to regulate light intensity and temperature inside the greenhouse. Its key functions include:
-
Light Regulation: By blocking a portion of sunlight, it prevents excessive light from damaging plants, especially those sensitive to light.
-
Temperature Reduction: It reduces solar radiation entering the greenhouse, effectively lowering the internal temperature and avoiding adverse effects on plant growth caused by high temperatures.
-
Energy Saving: It decreases the cooling load of the greenhouse, reducing energy consumption of air conditioning or ventilation systems.
-
Crop Protection: It prevents crop scorching or poor growth caused by excessive ultraviolet radiation.
-
Extended Cover Material Lifespan: It minimizes the aging effect of direct sunlight on greenhouse covering materials (such as glass or plastic).
The external shading system typically consists of shading nets, drive mechanisms, and control systems. It can automatically adjust the shading rate based on light intensity, temperature, or time, enabling intelligent management.
