0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; In addition to the greenhouse framework and covering materials, a standard multi-span greenhouse usually contains the followingGreenhouse supporting facilities, Customers can choose to install according to their own needs.

1. External shading system

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Installed on the top of the greenhouse, pulled by the motor, to adjust the sunlight regulation, shading, and cooling The role. The system adopts rack and pinion transmission. Press the switch button, the motor starts, and the sunshade net slowly unfolds. The external shading system in the supporting facilities of the greenhouse generally needs to be installed according to the needs of production management to control the shading rate.

2. Internal shading system

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; a layer of shade curtain system installed in the greenhouse. In the southern region of China, it generally only plays a role of shading, similar to the role of external shading systems. In the northern region of China, the greenhouse we built will replace the shade curtain of this system with a shade insulation curtain, which has both thermal insulation and shade fruit. This will not only reduce the cost of the greenhouse, but also have better performance.

3. Fan and wet curtain forced cooling equipment

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; The fan starts to exhaust air on one side to create a negative pressure in the greenhouse. On its corresponding side, the outdoor hot air becomes wet and cold air through the wet curtain and enters the greenhouse, thereby achieving the purpose of cooling.

4. Fan-wet curtain cooling system

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; The cooling is relatively fast, and it has become the most used supporting system for ventilation and cooling in the current greenhouse supporting facilities. The side window of the multi-span greenhouse is ventilated, the top window ventilation system is driven by a motor, and the window is automatically opened, which can open the window of the greenhouse.

5. Irrigation machine for greenhouse supporting facilities

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; adopt mobile spraying or drip irrigation equipment. If cultivation requires the use of a seedbed, a seedbed can be equipped. The nursery bed equipment is used for the nursery and planting of vegetables and flowers. The quality of the nursery bed net will affect the life of the mobile nursery bed. The seedbed net should have the characteristics of good corrosion resistance, acid and alkali resistance, friction resistance, strong support ability, and strong reflection ability.

6. The multi-span greenhouse is equipped with heating equipment

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Generally, round-wing greenhouse radiators or water heaters are used for heating. If conditions permit, you can use ground source heat pumps or solar photovoltaic panels for heating. These are the basic supporting systems required for a multi-span greenhouse, and can be selected according to the specific application. For some other requirements, you need to equip additional greenhouse supporting facilities, you can choose to add.
