What are the similarities and differences between internal shading systems and external shading systems in smart greenhouses?

There are some similarities and differences in the functions and functions of the internal shading system and the external shading system in the smart greenhouse.

Same point: 

1.Shade and cooling: Whether it is an internal shading system or an external shading system, one of their main functions is to block sunlight and prevent crops from being burned by strong light. By blocking a large amount of light from entering, it effectively reduces the accumulation of heat inside the greenhouse, thus having a cooling effect. 

2.Protect crops: Whether it is an internal shading system or an external shading system, they can protect crops from being burned by strong light, thereby benefiting crop growth and yield.

difference:

1.Location and design: The location and design of the internal shading system and the external shading system in the greenhouse are different. The external shading system is located outside the greenhouse and usually consists of brackets and screens to block sunlight. The internal shading system is located in the greenhouse and usually consists of a hanger and a curtain to block sunlight from entering the greenhouse through the windows. 

2.Ventilation: The ventilation of external shading systems is usually better than that of internal shading systems. The curtains of the external sunshade system can be opened to facilitate ventilation. The ventilation of the internal shading system is relatively poor because it is located inside the greenhouse and blocks part of the air circulation. 

3.Windproof performance: The windproof performance of external shading systems is usually better than that of internal shading systems. The curtain of the external sunshade system can block the invasion of wind and rain and play a windproof role. The windproof performance of the internal shading system is relatively poor because it is located inside the greenhouse and cannot block external wind and rain.

4. Installation method: The installation method of external shading system is usually simpler than that of internal shading system. The installation of the external shading system is generally carried out outside the greenhouse without entering the greenhouse, which is convenient for construction and maintenance. The installation of the internal shading system needs to be carried out inside the greenhouse, and requires the erection of hangers and other equipment, making the installation more complicated. In summary, there are certain differences between the internal and external shading systems in smart greenhouses in terms of location and design, ventilation, windproof performance, and installation methods. Choose a suitable shading system based on specific needs and actual conditions.
