The ventilation systems in our company consist of Roof Ventilation Systems and Side Ventilation Systems according to the difference of the installation position. The Roof Ventilation Systems include the Roof Track-Cross Ventilation System and Roof Row-Rack Ventilation System. The Side Ventilation System refers to the side Cooling-Pad Ventilation System. Moreover, we also supply the Roof or Side Plastic-Film Reeling Ventilation System (Manual or Electric).
Natural ventilation system, including the top of the track push rod, the window drive system uses the domestic quality products.
The greenhouse roof with one side gear rack push window, see the figure below is the top window application, greenhouse skylight size 4*1m, the greenhouse roof window direction single layout, window area accounts for about 10% of the area of the greenhouse. The opening mechanism drive system adopts the special gear rack, the transmission shaft and the push rod for the national standard galvanized steel pipe, which is adopted by the WJN40-2.6 reduction motor and track rod.
The roof window staggered materials refer to table 1, the window rack and pinion gear rack rail rod using special, product technical parameters see Table 2, gear motor using WJN40-2.6 motor speed; roof window interleaving technology parameters see table 3.
The opening and closing of the motor can be realized under the instruction of the operator. The motor comes with working limit and safety switch to achieve safe and reliable action.
The PC-sheet has great characters as light structure, impact resistant, good load performance, and high heat retaining property, also it is durable and economical, saving 40% energy than other covering materials.
Multi-span design, large interior space, high land utilization, very suitable for large-scale planting and mechanized operation.
Multi-span film greenhouse is an econmical greenhouse,popular among the users with its beautiful arc and low cost . The curved roof is beautiful and nice ,quite eye-pleasing . It consumes small amount of structural steel and provides good insulation property.
Greenhouse materials:The main structure of greenhouse adopts hot-dip galvanized pipe ,connected by galvanized bolts , with good corrosion resistance.
Main structure configuration:The inside and outside shading, seedbed, side window ventilation, water curtain , and fan cooling facility can be configured as demand .
Service life :more than 30 years for the main structure ; replace PC sheet every ten years.
Supporting Systems
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.
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.
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.
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
Irrigation system:
For special irrigation water requirements for flowers and plants, we have introduced international advanced water treatment technology, which can fully meet the requirements of irrigation water quality meeting to the standards of drinking water. We also can tailor the most appropriate water treatment system according to the customer's requirements.
