HUIJING ONE-STOP GREENHOUSE SOLUTION

1. Frame Structure

Hot dip galvanized steel frame has excellent performance of high strength, strong resistance to wind and snow, and good anti-corrosion. The quality is guaranteed for 20 years.

2. Covering Material
PO / PE film: 80-200 micron, anti-drip, anti-UV, quality assurance for 3-5 years.

Polycarbonate sheet: 6mm/8mm/10mm thickness, double layer hollow, anti-UV, anti-drip, good light transmittance performance, good thermal insulation performance, excellent strength, rigidity, hardness, toughness and crack resistance, quality assurance for 10 years.

Hollow glass: beautiful appearance, good light transmittance performance, thermal insulation performance is equivalent to polycarbonate sheet, quality assurance for 10 years.

Single-layer glass: beautiful appearance, excellent light transmittance performance, thermal insulation performance is not as good as polycarbonate sheet, quality assurance for 10 years.



3. Ventilation System

Roofing & Wall Ventilation



4. Shading System
(1) Outside Shading System: The main function of the system is to cool and shade in the summer, so that the sunlight diffuses into the greenhouse to ensure that the crop is protected from glare of the sun. Because it blocks a large amount of light, it effectively reduces the accumulation of heat inside the greenhouse, which generally reduces the greenhouse temperature by 4 °C to 6 °C.

(2) Inside Shading and Insulation System: When the inside shading net is closed, two separate spaces are formed in the greenhouse, which can effectively prevent the formation of mist and dripping in the greenhouse. In the winter and night, the inside shading net can effectively prevent the heat inside the greenhouse from overflowing through radiation or heat exchange, thus reducing energy consumption and reducing greenhouse operating costs.



5. Cooling System

Cooling pad + Exaust fans: The cooling is achieved by the principle of evaporation and cooling of water. The special wet cooling pad can ensure that the water evenly wets the entire wet curtain wall. When the air penetrates the wet curtain medium, it exchanges heat with the water vapor on the surface of the wet medium to achieve humidification and cooling of the air.


6. Heating System

Optional:(1) Coal-fired or gas-fired boiler + Spiral finned tube 
(2) Coal-fired or gas-fired boiler + heating fans
(3) Electric heating fans



7. Bench System
Moving bench: The bench bracket is made of hot-dip galvanized steel pipes. The bench frame is made of angle steel and aluminum alloy.
