III. Covering Materials: Heat Insulation, UV Resistance, Anti-Dew, Blocking Heat from the Source

1. High Light Transmission UV-Resistant PO Film
   1. Exclusive 5-layer co-extrusion process, adding triple additives of anti-ultraviolet, heat insulation and anti-dew, the light transmittance reaches 88%-90%, and at the same time blocks more than 90% of harmful ultraviolet rays to avoid rapid aging of materials;
   2. Surface anti-fog and anti-dew coating, the condensed water inside the shed flows down along the film without dripping on crops, greatly reducing humidity and reducing diseases, suitable for tropical high-humidity environment;
   3. Service life is 3-5 years, resistant to pulling and heavy rain impact, more than twice as durable as ordinary PE film.
2. Polycarbonate (PC) Sun Panel (High-End Model)
   1. Double-layer/four-layer hollow structure, the heat insulation performance is 40% higher than that of glass, and it can reduce the temperature inside the shed by 3-5℃ in summer;
   2. The impact strength is 200 times that of glass, which can resist typhoons and hail, with a 10-year warranty and a service life of more than 15 years;
   3. Diffused light design, uniform light without direct light spots, avoiding local burns of crops, suitable for high-value flower and seedling planting.
3. Sunshade and Cooling Combination Materials
   1. Equipped with aluminum foil sunshade net with 60%-80% shading rate, which can quickly reduce the temperature by 5-8℃ in summer, and can be electrically opened and closed to adjust the light on demand;
   2. Optional roof heat insulation coating, sprayed on the surface of covering materials, reflects more than 80% of solar radiation and enhances the cooling effect.

IV. Ventilation and Cooling System: Efficient Heat Discharge, Balanced Humidity Control, Adapt to Tropical High Temperature and High Humidity

• Natural Ventilation as the Main: Adopt top continuous butterfly window opening + side wall film rolling ventilation. The total ventilation area is ≥25% of the shed area (higher than the temperate standard). Using the principle of hot air rising, a “wind pulling effect” is formed, with 15-20 air exchanges per hour, quickly discharging hot and humid air.
• Mechanical Ventilation as Auxiliary: In hot and stuffy weather, configure a combination of high-power negative pressure fans + wet curtains. The fans are installed at the south end, and the wet curtains are installed at the north end to form negative pressure ventilation. The high-temperature air is cooled by evaporation through the wet curtains, which can stabilize the temperature inside the shed at 25-30℃ (still applicable when the outdoor temperature exceeds 40℃).

Internal Circulation Fans: Install circulation fans inside the shed to break the stagnant air area, ensure uniform temperature and humidity, avoid local high temperature and high humidity, and reduce the difference in crop growth.

V. Full-Scenario Adaptation: From Growers to Enterprises, Covering Diverse Tropical Planting Needs

• Small-Scale Growers: Recommend simple multi-span film greenhouses with controllable cost and easy installation, combined with basic ventilation + sunshade systems to meet the basic planting of leafy vegetables and tropical fruits.
• Large-Scale Bases: Choose zigzag multi-span greenhouses with a multi-ridge roof design, which increases ventilation efficiency by 30%, suitable for high-value crops such as tomatoes, cucumbers and flowers.
• High-End Planting/Seedling Raising: Adopt PC board greenhouses + intelligent temperature control systems to automatically control ventilation, sunshade and wet curtains, accurately adjust temperature and humidity, and realize efficient year-round planting.
