3.Outside Shading System
Characteristics:
· Anti-UV, anti-hail
· Shading net with different shading rates (60%, 70%, 75%)
· Cooling and shading
Specification of outside shading system
The main function of the system is shading and cooling in summer and making sunshine diffuse in greenhouse and preventing crops from strong light. It can reduce internal heat accumulation of greenhouse effectively. Generally, it can reduce greenhouse temperature for 4-6ºC.
Outside shading system consists of outside shading structure, shade curtain, transmission mechanism and power device, system support and other fixed parts. It adopts A type rack and pinion screen type.
Outside shade system can improve the inside ecological environment by adapting sunlight strength. In summer, the shading screen can block the sunlight according to different shading rate, and diffuse sunlight into the interior part. Meantime, it can reduce the temperature in greenhouse.

4.Inside Shading System
Characteristics:
· Anti-fog and anti-drip
· Energy-saving and insulation
· Water-saving
· Double shading systems
· Curtain: permeable & insulating curtain
Specification of inside shading system
Double layer inside screen system can be used to increase indoor moisture retention effect.
The curtain is divided into permeability and moisture retention tow different types. Select the curtain of different types and shading rates according to the client's need.
5.Ventilation System
Specification of ventilation system:
Greenhouse ventilation system can be divided into two kinds of ventilation systems. One is continuous ventilation system. The other is interlacing ventilation system. Both of these two kinds of ventilation systems are now widely used in agricultural planting, sightseeing and entertainment and other fields.

Interlacing Ventilation System |
Characteristics of Greenhouse Ventilation Systems:
1. Staggered windowing design is used for the top-vent so as to strengthen convection effect of the air. Opening angle can reach 30°. Apply different opening according to climate difference inside and outside. Ventilated area can take up more than 20% of top surface area of greenhouse.
2. Overall mechanical transmission mode is used for side-vent. It is matched with the top-vent for cooling. Use evasion type or push-pull type side window.
3. The unique window opening outer fly net design can prevent the insect and sundries entering greenhouse and reduce infection on greenhouse crop. Gear and rack transmission mode and electric control are used for the top-vent or side window
6.Cooling System
Specification of the cooling system:
Use evaporation cooling principle of water to realize cooling. There is a specially-made hydrophobic wet pad wall. When the air penetrates wet curtain medium, it conducts heat exchange with vapor on moist medium surface so as to realize humidification and cooling for the air.
Facilities of the cooling system:
1) Wet Pad:Wet pad, aluminum alloy frame and wet pad water supply system.
2) Fan Size:1380×1380mm, 1000×1000mm,750×750mm
7.Heating System
Heating facilities:
Boiler
a.Gas-fired boiler
b. Coal-fried boiler
c. Bio combustion boiler
Heating pipe
Gardening heater fan
Radiator
5.HFW Radiating pipe
8.Irrigation System
1. Irrigation and fertilization water treatment system with reasonable design improves absorption function of crops toward fertilizer. Meanwhile, it improves crop quality.
2. It is especially suitable for the area with poor water quality and crop greenhouse which has high requirements for planting water quality.
3. The advanced treatment process is combined with greenhouse production process effectively.
9.Automatic control system.
The greenhouse need to configure a set of electric control system. The control system can be used to realize the centralized control of the inside shading system, the fan and wet pad cooling system.
All main power lines in the greenhouse are placed in the metal wire slot.
Into the line using three-phase five wire system, the main body of the greenhouse to do ground treatment.
Electric control cabinet adopts GB products. Indoor wiring uses metal bridge, wire made of RVV plastic sheath wire.
Distribution box
Simple description
1. The electric control box is placed in the indoor temperature, which is convenient for the installation and debugging and maintenance of the equipment in the greenhouse.
2. The lead in the greenhouse is damp proof insulated wire.
3. Temperature indoor use TN-S grounding system; with leakage switch.
4. Users will three-phase five wire power into the indoor temperature control box, the power fluctuation of less than ±10%, the electrical equipment using ambient temperature -10ºC to 40 ºC.
5. Main parts of the layout of the line, the extension of the tube.
10. Greenhouse Aluminum Profile
Special used for PC sheet Aluminum Profile installation.
