What are the similarities and differences between the internal and external shading systems in intelligent greenhouses?
There are some similarities and differences in the function and function of the inner and outer sunshade systems in intelligent polytunnel greenhouse.
Similarities:
1. Shading and cooling: Whether it is an internal shading system or an external shading system, one of their main functions is to shield the sun and prevent crops from being burned by strong light. By blocking the entry of a large amount of light, it effectively reduces the accumulation of heat inside the greenhouse, thus having a cooling effect.
2. Protect crops: Whether it is an internal sunshade system or an external sunshade system, they can protect crops from strong light burns, which is conducive to the growth and yield of crops.
The difference:
1. Location and design: The location and design of the inner sunshade system and the outer sunshade system are different in the polytunnel greenhouse. The outer sunshade system is located outside the polytunnel greenhouse and usually consists of a bracket and curtain to block out the sun. The internal sunshade system is located in the greenhouse and is usually composed of hangers and curtains to block sunlight from entering the greenhouse through the window.
2. Ventilation: The ventilation of the external shading system is usually better than that of the internal shading system. The curtain of the external sunshade system can be opened to facilitate ventilation. The internal sunshade system is relatively poor in ventilation, because it is located inside the greenhouse and blocks part of the air circulation.
3. Wind performance: The wind performance of the external shading system is usually better than that of the internal shading system. The curtain of the outer sunshade system can block the invasion of wind and rain and play a windproof role. The wind performance of the internal sunshade system is relatively poor, because it is located inside the polytunnel greenhouse and cannot block the outside wind and rain.
4. Installation method: The installation method of the external sunshade system is usually easier than the internal sunshade system. The installation of the external sunshade system is generally carried out outside the polytunnel greenhouse, and there is no need to enter the inside of the greenhouse, which is convenient for construction and maintenance. The installation of the internal sunshade system needs to be carried out inside the polytunnel greenhouse, and equipment such as hangers need to be set up, and the installation is more complicated.
To sum up, there are certain differences between the internal and external shading systems in the intelligent greenhouse in terms of location and design, ventilation, wind performance, and installation mode, and the appropriate shading system is selected according to the specific needs and actual conditions.
