A glass greenhouse serves as a state-of-the-art sanctuary for plant cultivation, utilizing the exceptional light transmission properties of glass to establish optimal lighting conditions crucial for robust plant growth. With impressive light transmittance levels of 85%-90%, glass allows the majority of visible sunlight to permeate, fostering an environment where plants thrive on enhanced photosynthesis. Additionally, it adeptly preserves indoor temperatures, creating an isolated microclimate that operates independently from the whims of external natural elements. During the brisk chill of colder seasons, glass greenhouses stand as a bastion of warmth, curbing heat loss and providing essential insulation. Conversely, in the sweltering months, these greenhouses employ advanced ventilation, shading, and supplementary technologies to finely tune the internal temperature, safeguarding plants from excessive heat stress and ensuring their continued prosperity.
A glass greenhouse is a building facility with a specific frame structure. Frames are usually made of metal (such as steel), including columns, beams, trusses and other parts, which are combined to form a solid spatial framework to provide support for the installation of glass. The design of the frame should take into account the weight of the bearing glass and the pressure of resisting natural external forces such as snow and snow to ensure the safety and stability of the greenhouse. |
1. Glass greenhouse is mainly used for plant cultivation. It uses the good light transmission of glass to create suitable lighting conditions for plant growth. The high transmittance of glass (generally more than 85%-90%) can make most of the visible light in the sun pass through, ensuring that plants can fully carry out photosynthesis. At the same time, it can effectively maintain the indoor temperature and form a microclimate that is relatively independent of the external natural environment. In the cold season, the glass greenhouse can reduce the loss of indoor heat and play a role in insulation; In the hot season, the temperature is adjusted through supporting ventilation, shading and other facilities to avoid excessive temperature damage to plants.
2. In addition to plant cultivation, glass greenhouses can also be used for agricultural production activities such as flower planting and vegetable seedling cultivation, and in some cases, it is also used to display rare plants and hold horticultural exhibitions, such as tropical plants in some botanical gardens, flower exhibition greenhouses, etc., to provide people with places of appreciation and popular science education. |
A glasshouse is a semi-permanent or permanent building. Its construction needs to follow certain building codes and standards, and there are corresponding requirements in site selection, infrastructure construction, drainage, etc. Its appearance is usually more structured to adapt to the installation of glass and the use of internal space. And the scale of the glass greenhouse can be flexible according to actual needs, from small single-house greenhouse for home gardening, to large multi-house greenhouse for agricultural industrialization. |
Ventilation system
1. Natural ventilation system: This system primarily harnesses the ingenuity of nature, utilizing side windows and top windows to achieve optimal air circulation. The side windows, typically located on the greenhouse sides, can be manually or electrically operated, providing flexibility and convenience. At the pinnacle of the greenhouse, the top window opens in various sophisticated ways, like rack and pinion mechanisms. As indoor temperatures rise, hot air naturally ascends and exits through the top window, while cool outside air gently flows in through side windows, creating a seamless natural ventilation cycle that harmoniously balances the indoor climate.
2. Forced ventilation system: For those times when natural methods fall short, especially during the scorching summer heat, the forced ventilation system takes the lead with its powerful exhaust fans, strategically placed at one or both greenhouse ends. This system efficiently expels hot, stagnant air, swiftly drawing in fresh, cooler breezes from outside, achieving rapid cooling and revitalizing ventilation with unparalleled efficiency.
Sunshade system
1. External sunshade system: Elegantly positioned atop the greenhouse's exterior, this sunshade net, operable either automatically or manually, adjusts its span in response to the sun's intensity and the indoor climate. Its primary purpose is shielding the greenhouse from excessive solar radiation, effectively diminishing light intensity and heat influx. This system ensures that during the peak summer heat, the greenhouse remains comfortably cool, and plants are safeguarded against intense light-induced stress.
2. Internal sunshade system: Positioned internally, this system serves dual purposes: providing essential shading and cooling during the day, while doubling as a heat-preserving barrier at night. By reflecting sunlight and minimizing heat absorption, it adeptly regulates light distribution, fostering a balanced and conducive environment for plant growth within the greenhouse.
Irrigation system
1. Drip irrigation system: A hallmark of precision in modern irrigation, this method delivers water meticulously to each plant via drip heads positioned near the roots. With its slow, steady release, drip irrigation minimizes evaporation and wastage, allowing for precise water management. Furthermore, it supports nutrient delivery through dissolved fertilizers in the water, ensuring every drop nourishes the plants, making the system a paragon of efficiency and sustainability.
2. Micro-sprinkler irrigation system: This innovative sprinkler system, positioned above plants or at strategic heights, disperses water as fine droplets, enhancing air humidity levels. Ideal for plants with high humidity needs, it covers vast areas, simultaneously nurturing multiple plants, ensuring even and efficient irrigation across the greenhouse.
Heating system
1. Hot water heating system: By channeling heated water through a network of pipes, this system radiates warmth evenly throughout the greenhouse space or floor. Its efficient heat distribution and easy temperature control make it a reliable choice. Additionally, it ingeniously repurposes waste heat for auxiliary tasks like hot water irrigation, underscoring its resourcefulness.
2. Hot air heating system: This system harnesses the power of hot air fans to rapidly elevate greenhouse temperatures. Its adaptable design allows for precise adjustments to air outlet positions and angles, ensuring strategic and even heat distribution, tailored to the needs of the plants and the greenhouse layout.
Control system
This sophisticated intelligent control system serves as the greenhouse's brain, autonomously monitoring and regulating vital environmental parameters such as temperature, humidity, light, and ventilation. A network of sensors-temperature, humidity, light-captures a wealth of data, seamlessly transmitting it to the controller. The system then automatically adjusts the operational state of ventilation, shading, irrigation, and heating equipment based on pre-set values, ensuring precise environmental control and optimal conditions for plant cultivation.
