Outer Sunshade System
Function: Outer sunshade systems are installed on the exterior of the greenhouse structure, typically attached to the framework or supported by poles. They consist of shading materials, such as shade cloths or screens, that intercept sunlight before it reaches the greenhouse.
Temperature Regulation: Outer sunshade systems prevent excessive solar radiation from entering the greenhouse, thereby reducing heat buildup inside the structure. By blocking sunlight before it reaches the greenhouse, they effectively lower the ambient temperature.
Protection from Heat Gain: They provide protection from heat gain during periods of intense sunlight, helping to maintain a more stable and comfortable environment for plant growth.
Light Transmission Control: Outer sunshade systems offer greater control over the amount of sunlight entering the greenhouse compared to inner systems. By adjusting the shading level from the outside, growers can fine-tune light transmission based on changing weather conditions and crop requirements.
Differences:
Location: Inner sunshade systems are installed inside the greenhouse, while outer sunshade systems are installed on the exterior.
Direct vs. Indirect Shading: Inner sunshade systems shade the interior of the greenhouse directly, while outer sunshade systems intercept sunlight before it reaches the greenhouse, providing indirect shading.
Light Control: Outer sunshade systems offer more precise control over light transmission, as they can be adjusted from the outside of the greenhouse.
Heat Reduction: Outer sunshade systems may be more effective at reducing heat buildup, as they block sunlight before it enters the greenhouse, whereas inner systems intercept sunlight after it has entered the structure.
Both inner and outer sunshade systems have their advantages and are often used in combination to achieve optimal light and temperature levels in the greenhouse, depending on factors such as climate, crop requirements, and grower preferences.
