2018 Single Span high tunnel agriculture greenhouse

Greenhouse frame

The greenhouse frame is made of the materials of galvanized steel, connected by screws, bolts or suitable connectors. Door, gutters, etc. can be equipped and the roof can be pitched roof (supported by rectangular tubes) or arched roof (supported by circular tubes). The uprights of greenhouse is made by the rectangular tubes.

Covering material

1. Glass is available on the roof or the side of the greenhouse, thickness of which can be 4mm or 5mm. 

2. PC(Poly-carbonate) sheet, hard and durable, anti-ultraviolet, can be available on the roof and the side of greenhouse, thickness of which are, for example, 8mm or 10mm.

3. Film, heat-preserving and durable, can be available on the roof and side of the greenhouse, thickness of which can be 8mm, 10mm, 12mm, 15mm, 20mm, etc. And more layers of the film can be used on the greenhouse.

Plastic film greenhouses have many properti- es that make it one of the most useful and pr- actical greenhouses. Its low cost, large film s- ize, easy to attachment and good light trans- mission are characteristics that have helped to expand its use so that now it is the most c- ommon covering. For people who just want t- o start their first greenhouse business, plastic film greenhouse would definitely be their first best choice.

External Shading System:

The primary function of the system is to cool the heat in summer; the sun would diffuse into the greenhouse to ensure that crops from strong light burns. Due to blocking a significant amount of light into the room, it can effectively reduce the accumulation of heat in the greenhouse, drop 4°C to 6°Cof room temperature.

Features:

Anti-ultraviolet, anti-hail, reduce the damage to the top of the greenhouse.

According to the different crops, use different shade curtains to meet the needs of various plants under the sunlight.

In summer, through the shade curtain can efficiently reflect part of the sunlight, drop room temperature 4 to 6 degrees Celsius.

Internal Shading/Insulation System:

Anti-fog and anti-drip: After close the inner shading system, it will form two separate lower and upper spaces in the greenhouse, this can effectively prevent the formation of the fog in the greenhouse and the dewdrops. To increase the indoor insulation effect, we can use double shade system. The curtain has two types, breathable curtain, and insulated curtain, like waterproof space cotton insulation blanket. According to the need, we choose different light transmission capacity of the shade curtain or insulation curtain.

Energy saving and insulation: In winter and night, it can effectively prevent the heat inside the greenhouse through the radiation or heat exchange spill, thus reducing energy consumption and greenhouse operating costs.

Ventilation System

The way of opening the top window includes one-side top window drove by rack and pinion, two-sides top window drove by rack and pinion, staggered top window drove by rack and pinion, electric roll top window, side window drove by rack and pinion, electrical roll side window, sliding window, etc.

The rack and pinion system has some rack and pinion racks. Under the action of the drive shaft, the greenhouse windows open. Due to conform to the direction of hot air flow, it can be conducive to the flow of air and summer cooling and dehumidification. This system can effectively improve the greenhouse ventilation area, reduce costs, applicable to all types of greenhouse. Ventilation rate is up to 27%.

   Cooling System

Cooling pad and exhauster cooling system is the most cost-effective cooling system for large-scale production facilities. The system has the advantages of simple equipment, low cost, low energy consumption, significant cooling capacity and reliable operation. The cooling pad and exhauster cooling system consist of the specialized paper cooling pad, low pressure and high flow axial fan, water circulation system, and control device. Exhausters were installed on both sides of the gable in the greenhouse or closed houses. When it is working, the negative pressure room caused by exhausters can force the hot air flow outside, water evaporation will absorb a significant amount of latent heat, to achieve reducing indoor temperature and increase the humidity.

Good cooling effect: It has small cooling pad wind resistance, high evaporation efficiency, also can withstand high over-current wind speed, so that the unit area of the cooling pad can make more air through and cooling. Proper maintenance cooling pad of cooling system can guarantee 75% -80% of the cooling efficiency.

Moist air purification: The air through the cooling pad into the greenhouse is more fresh and humid, and more suitable for crop growth.

Smooth operation: The cooling pad and exhauster system provides a simple and cost-effective way to cool down. The mechanical part is only the water pump and exhaust fan, and it has a better cooling effect used with shade system.

Exhausters

Fuer exhauster created the first full plastic exhausters in domestic. Products are CAD / CAM design, with characteristic of strong anti-corrosion, low noise, large volume, smooth operation, long lifetime, high efficiency, and its shutters can automatically open and close, it achieved dust-proof, waterproof, beautiful and other effects. It is the best ventilation choice for the modern workshop, agricultural greenhouse and livestock farm. Compare to regular galvanized steel alloy exhauster; it only causes little noise.

 Heating System

Heating Finned Tube (ø76mm)

The heating finned tube is the standard plumbing heating tool, it has a large heat dissipation area and the temperature increases fast but cooling slow down. It has no side-effect on the crop growth. It also has anti-corrosion, long lifetime and other advantages.

Heating Fan (800*800mm/1000*1000mm)

Equipped with a flame detection device, safe and reliable combustion, fully automatic operation.

Light Compensating System

Vegetables, flowers and other plants usually cultivated in the winter and spring when the sunlight time is short and weak. Illumination is the critical limiting factor in plant growth, so the greenhouse light compensating system has become an indispensable equipment. The use of artificial light source can compensate light for crops intimate sunlight and obtain better product quality and efficiency.
