Audited Supplier solar greenhouse
| A solar greenhouse is a multi-functional building that combines a photovoltaic power generation system with a greenhouse.It uses the space on the top of the greenhouse to install photovoltaic panels, which can absorb solar energy and convert it into electricity, while providing the required light and temperature for crops in the greenhouse.This design not only conserves land resources but also enables the bidirectional utilization of energy. Its main principle is to use the greenhouse effect, that is, sunlight shines through transparent glass or plastic film into the greenhouse, which is absorbed by plants and soil and converted into heat energy, so that the temperature in the greenhouse rises. At the same time, long wave radiation can block heat or little heat is lost to the outside through glass or plastic film, so that the greenhouse can maintain a higher temperature. |
In order to reduce heat loss, people can take the following measures:
| 1.Sealing: Ensure that the doors, windows and vents of the greenhouse are well sealed to prevent heat loss through air convection. |
2.Thermal insulation: add thermal insulation materials to the walls, roofs and other parts of the greenhouse, such as double-layer glass, foam board, etc., to reduce heat loss through heat conduction.
|
3.sunshade: a sunshade net or a sunshade shed is arrange outside that greenhouse to shade part of sunlight and prevent the temperature in the greenhouse from being too high. |
4.Ventilation: Set up ventilation openings reasonably, use natural wind or fans for ventilation, and reduce the temperature and humidity in the greenhouse.
|
5.Water source: set up water source in the greenhouse, such as pool, spraying equipment, etc., to reduce the temperature in the greenhouse through evaporation and heat absorption of water.
|
6.Plant selection: select plants suitable for high temperature environment to improve the ecological benefits in the greenhouse.
|
Through the above measures, the heat loss of solar greenhouse can be effectively reduced, the energy utilization rate in the greenhouse can be improved, and a good growth environment can be provided for plants.
If a heat storage device is installed indoors, this excess heat can be stored. Solar greenhouses do cool down at night because of heat loss, so some measures need to be taken to reduce heat loss and ensure that the temperature in the greenhouse remains at a suitable level.
Here are some common practices:
|
1* * Insulation * *: The use of efficient insulation in the walls and roofs of greenhouses can significantly reduce the loss of heat through conduction. These materials include foam board, glass wool, rock wool and so on.
|
|
2 * * Thermal insulation quilt * *: Covering the outside of the greenhouse with thermal insulation quilt or mobile thermal insulation curtain can provide additional thermal insulation effect at night. These insulation materials are usually turned on during the day to allow sunlight in and turned off at night to retain heat.
|
|
3 * Multi-layer covering * *: Use double-layer or three-layer covering materials (such as double-layer plastic film or glass) to form air insulation layers, which can provide better thermal insulation effect.
|
|
4* * Heat storage device * *: As mentioned earlier, heat storage devices can store excess heat during the day and release it at night to help maintain the temperature of the greenhouse. This may be a hot water system, a bed of rock, or a phase change material, etc.
|
|
5* * Ventilation control * *: Proper ventilation can help regulate the humidity and temperature in the greenhouse, but too much ventilation can lead to heat loss. Therefore, automatic vents or wet curtains can be used to control the amount of ventilation to reduce heat loss.
|
|
6* * Ground heating * *: The ground is an important heat source inside the greenhouse. With a floor heating system, such as a geothermal wire or hot water pipe, the floor can be kept warm, reducing overall heat loss.

| According to the use: |
| -Exhibition greenhouse: It is mainly used to display plants, and usually needs good visual effect and suitable environmental conditions to attract visitors. -Cultivation and production greenhouses: used for large-scale cultivation and production of plants, with emphasis on improving crop yield and quality. -Propagation greenhouse: specialized for plant propagation, such as breeding, tissue culture, etc., requiring fine control of environmental conditions. |
| According to the indoor temperature: |
| -High temperature greenhouse: suitable for tropical and subtropical crops, the indoor temperature is maintained at 18-36 ºC in winter. -Moderate temperature greenhouse: suitable for temperate crops, the indoor temperature is maintained at 12-25 ºC in winter. -Low temperature greenhouse: It is suitable for cold zone crops or cold-resistant plants, and the indoor temperature is maintained at 5-20 ºC in winter. -Cold room: used to store and handle plants or products that need to be kept at a lower temperature. In winter, the indoor temperature is maintained at 0-15 ºC. |
1) Internal sunshade: Install a sunshade net inside the greenhouse. Rack and pinion drive, smooth running, high control accuracy, long service life, easy maintenance.
2) External sunshade: Install a sunshade net on the top of the greenhouse to prevent indoor crops from being burned by strong light in summer, reducing the indoor temperature by 4-6 ° C.
3) Cooling fan: moisture ventilation to ensure crop growth.
4) Cooling pad: The principle of evaporation cooling is used to achieve the purpose of cooling.
5) Drip irrigation system: has a high water-saving and yieldincreasing effect, can be combined with fertilization, fertilizer efficiency increased by more than double.
6) Mobile sprinkler irrigation: sprinkler irrigation is not only a water-saving, yield-increasing, efficient irrigation method, but also a high energy consumption irrigation method.
7) Fertilization system: save fertilizer, improve water use efficiency, reduce pests and diseases, improve crop yield and improve quality.
8) Heating system: uniform heat dissipation, good insulation effect.
9) Mobile seedbed: manual drive, simple operation, simple movement, moisture-proof.
10) Growth light :LED growth lights control plant growth by adjusting light.
Heating system
Fully avoid the positive pressure combustion brought about by the furnace wet uneven, opaque combustion, flue gas overflow, local burning loss and other defects. Positive pressure multistage circulation heat transfer technology, so that the heat transfer in every corner, so that the heat exchange more complete, more adequate. Fresh air, uniform temperature, controllable: comfortable and warm breeding environment. Unique dual fan forward-looking design (energy saving + backup).
Cooling system
The wet curtain and the fan constitute a cooling device, and the working principle of the wet curtain is "water evaporation absorbs heat", so as to achieve the purpose of cooling. The fan frame adopts advanced automatic processing technology with high precision. Extra thick galvanized layer, strong corrosion resistance, to further achieve the purpose of cooling
