The greenhouse mesh has a simple structure, beautiful appearance, and cost-saving. It does not stand upright in the greenhouse cover. The insect barrier net relies on sunlight to meet the needs of plant growth. Even if it is cold, there is no need for a heating system. The walls on the three sides keep warm and have excellent thermal insulation properties. The greenhouse mesh is hard and durable, bears load or strongly resists the pressure of wind or snow. It can be used for planting flowers and vegetables all year round. What are the structures and systems of greenhouse insect net?
1. Steel structure
Main galvanized frame (main column according to wind load and snow load).
2. Roof cover
Greenhouse films (PE, PVC, EVA, PO) have different thicknesses (from 80 microns to 200 microns).
3. Insulation system
In cold weather, it uses pads to keep warm.
4. Ventilation system
There is a ventilation device on the top of the greenhouse mesh.
5. Cooling and heating system
(1) The cooling system is composed of cooling fans and cooling pads, which can keep the greenhouse temperature at 26-30℃ in summer
(2) There are two kinds of heating temperature, one is using boiler and the other is using electricity. The boiler fuel can be coal, oil, natural gas and biofuels. The boiler needs to lay pipes and fill the blower with water for heating.
If you use electricity, you need to use an electric heater.
6. Shading system
Usually, there are outdoor shading systems in such greenhouses.
7. Irrigation system
There are drip irrigation and spray systems to choose from.
