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. |
Through these methods, even at night when there is no solar radiation, the temperature in the solar greenhouse can be kept relatively stable, providing a more comfortable growth environment for plants.
Solar greenhouses are classified primarily based on their use and indoor temperature requirements.The following is the classification of solar greenhouses according to these two criteria:
| 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.
External shading system
It main function of the system is to shade and cool down in summer, so that the sun diffuses into the greenhouse, ensuring that the crops are not burned by strong light, and effectively reduces the accumulation of heat inside the greenhouse because it blocks the entry of a large amount of light. Anti-ultraviolet, anti-hail, reduce the damage to the top of the greenhouse. According to the different planting crops, the selection of different shading rates of the curtain to meet the needs of different crops for sunlight.

Inner shading system
Anti-fog and anti-drip: When the inner sunshade system is closed, two independent Spaces are formed in the greenhouse, which can effectively prevent the formation of fog and drip dew in the greenhouse. Energy-saving insulation: in winter and at night, it can effectively prevent the internal heat of the greenhouse from spilling out through radiation or heat exchange, thereby reducing energy consumption and reducing the operating cost of the greenhouse.
