Understanding the Connection Between Greenhouse Shading Systems and Shade net

Shade Net plays an essential role in greenhouse shading systems, which can be divided into two types based on their location: exterior and interior shading systems. The choice of shading materials and their functions depends on the system`s location.

1. External Sunshade Series
Exterior shading systems are set up outside the greenhouse on the roof, blocking excess sunlight and preventing it from raising the indoor temperature. This method offers the most effective cooling. Since the shade cloth is outdoors, it doesn`t directly influence other environmental factors within the greenhouse, focusing primarily on temperature reduction and light regulation.

2. Inner Sunshade Series
Interior shading systems involve installing shade cloth inside the greenhouse to manage excess sunlight. When sunlight enters the greenhouse, it is partially reflected and absorbed by the shade cloth. The reflected sunlight bounces back into the greenhouse, while the absorbed portion heats the shade cloth, which in turn transfers heat to the indoor air. Consequently, interior shading`s cooling effect is slightly less effective than exterior shading. However, when used with a wet curtain and fan cooling system, interior shading considerably boosts cooling efficiency, improving airflow and reducing the need for cooling and ventilation.

In modern greenhouses, selecting the right shade cloth material can provide additional benefits like thermal insulation, humidity control, and drip prevention. Aluminum foil shade cloth is popular due to its airtightness and ability to absorb and reflect far-infrared radiation, offering excellent thermal insulation. Made from moisture-absorbing polyester fibers, this shade cloth can also regulate humidity. Moreover, its higher temperature prevents condensation, and its fibers can absorb and support dripping condensation from the greenhouse covering material, significantly reducing dripping problems.

Given its many functions, interior shading is more cost-effective and practical than exterior shading, making it a more common choice for modern greenhouses.

Conclusion

Choosing the best shade cloth for your greenhouse involves considering factors such as plant requirements, climate conditions, shading effectiveness, cooling efficiency, and durability. Additionally, when selecting a shade cloth, it`s important to determine whether it will be used for interior or exterior shading to ensure optimal shading and cooling effects in different application scenarios, ultimately promoting plant growth and yield within the greenhouse.
