The entire external sunshade system is reliable and beautiful.
C. net bracing string
Domestic black poly string, 0.4m between two strings.
D. Control box
The control box can realize the folding and unfolding of the sunshade net by automatic control (stop by lead limit switch) or annual control (stop by pressing stop button).
E. Sunshade net
Color: black, rate of shading: 90%, reliable quality
1.7 Greenhouse ventilation system
One set electrical rolling film skylight will be set on the each side of every arch roof, width: 1.5m, length: 48m, totally 13 sets. 2 set electric rolling film windows will be set on both eastern and western sides, totally 4sets; two sets electric rolling film widows will be set on the northern side behind the wet curtain. The electric rolling film window includes film roller, drive shaft and anti-insect net.
1.8 Greenhouse drainage system
The greenhouse uses gutter to drain, φ110PVC water down pipe and adapting pieces, totally 28 sets.
1.9 Pad-fan cooling system
1.9.1 Designing principle
Pad-fan cooling system uses evaporation related heat absorption principle to realize cooling purpose. Wet pad system selects domestic high quality aluminum alloy frame and pump water circulation system. The core of the cooling system is to let the water evenly go throughout the wet pad. The pad-fan cooling system is now an effective way of cooling largely used in multi-span greenhouses.
When the greenhouse needs to cool, close all the windows and doors, except the window in the back of the wet pad, then start the fans to take out the hot air inside the greenhouse, at this time, negative air pressure forms, then start the pump to let the water go throughout the wet pad, the external air go through the wet pad due to the negative air pressure, and the water in the pad evaporates and absorbs the heat from the external air, then cold air get inside the greenhouse, the greenhouse get cool.
1.9.2 Basic composition of pad-fan cooling system

2.0.2 Electric power system:electric distribution box,motors
2.0.3 Electrical parameters:
External sunshade motor:0.55kw/set*2=1.1kw
Electric rolling film reeler:0.1Kw/set*=0.6kw
Skylight film reeler:0.1kw/set*13=1.3kw
Axial flow fan motor:1.1Kw/set*22=24.2kw
Wet pad water pump motor:2.2Kw/set*2=4.4kw

2.0.6 Installation requirements of electric distribution box and wires:
the electric distribution box needs to be installed inside the greenhouse for the convenience of greenhouse equipment installation and maintenance.
the electric distribution box need to be dry and faraway from the irrigation equipment.
the electric distribution box needs to have good ground connection, the leakage protection switch should be installed.
each wire terminal should be cold-press terminal.
