REXI greenhouse glass is greenhouse where glass is the main light-transmitting material. It has long service life, suitable for a variety of regions and a variety of climates.
In the China greenhouse glass factory, the construction model is divided into the span size and the opening size, and it is divided into different types: vegetable, flower, nursery, ecological, research, three-dimensional, profiled, leisure, smart glass greenhouses and so on. Its area and usage method can be freely deployed by the holder, the smallest courtyard leisure type, a large height of up to 10 meters, a span of up to 16 meters, opening up to 10 meters, the degree of intelligence can be achieved by a key control. The heating problem of glass greenhouses in winter can use multiple heating methods. The energy consumption costs are in the middle and most of them can be accepted. The higher the greenhouse glass price is, the lower the energy consumption cost is.
The main purpose of ventilation for China greenhouse glass suppliers is to eliminate the residual heat in greenhouses and the moisture in greenhouses, adjust the air content, remove harmful gases, and make the conditions of greenhouse temperature, humidity and air suitable for plant growth.
In the glass greenhouses in northern China, warming is needed in winter. The duration of heating in the greenhouse is different. Planting flowers or growing seedlings in the southern region also requires warming or temporary warming.
The heat loss in greenhouses mainly through the following ways: Conduction of heat through the glass enclosure structure, can account for 70% to 80% of the total heat loss; Radiant to the sky cooling; Ventilation and heat dissipation; Air permeability heat dissipation; Ground heat transfer. Energy conservation is to reduce the amount of heat generated in the greenhouse. An effective method recommended by China greenhouse glass manufacturers is to install insulation screens, which can reduce heat loss at night. Under the premise of meeting the crop illumination, it is better to install double-layer transparent material, and the heat loss can be reduced by 50%. The use of cold-proof ditch, filled with insulation materials to reduce heat transfer in the ground is also very effective.
