Greenhouse Inside Shading System for Cooling Down

Greenhouse Inside Shading System for Cooling Down

Function: energy-saving insulation;reflective shading;control light

Features: aluminum foil + polyester film closed

The shading and heat preservation screen is made of special aluminum foil and polyester film woven by high-strength polyester yarn.With excellent radiation reflection and transmission function, it can make room temperature lower in the daytime, therefore creating ideal energy saving effect. The temperature of crops at night is basically the same as that of the surrounding environment.Good indoor climate conditions avoid leaf dew, reduce pests and diseases and reduce energy costs.It is soft and easy to be folded to be small size so as to ensure the maximum light transmittance

The braided structure is convenient for water vapor to pass through, and can effectively prevent the bottom surface of the curtain from dewing and forming moss. It can stay clean after using for many years

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.
