The Glass Greenhouse, a marvel of innovation, is primarily designed for optimum plant cultivation. Utilizing the unparalleled light transmission capabilities of glass, it establishes ideal lighting conditions for robust plant growth. With a remarkable transmittance rate exceeding 85%-90%, glass allows a significant portion of the sun's visible light to penetrate, ensuring that plants are bathed in the light necessary for vigorous photosynthesis. This structure not only sustains an optimal indoor temperature, fostering a microclimate distinct from the external natural environment, but also serves multiple functions throughout the seasons. During colder months, it significantly curtails heat loss, acting as an effective insulator. Meanwhile, in warmer periods, through the integration of advanced ventilation, shading, and other supportive systems, the greenhouse adeptly manages internal temperatures, safeguarding plants from potential heat-induced stress.
| 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 relies on both side and top windows to ensure effective ventilation. Side windows, generally positioned on the greenhouse's flanks, can be operated either manually or automatically. The top window is strategically located at the greenhouse's summit and offers various opening mechanisms, including rack and pinion. As the indoor temperature escalates, warm air naturally ascends and escapes through the top window, while cooler exterior air enters via the side windows. This natural exchange remarkably moderates indoor temperature and humidity levels, ensuring an optimal growing environment.
2. Forced Ventilation System: This system is enhanced with exhaust fans, which are strategically installed at one or both ends of the greenhouse. When natural ventilation falls short, particularly during sweltering summer days, the exhaust fans can be activated to expel overheated air efficiently. Simultaneously, fresh air is drawn in from outside, resulting in a swift cooling effect and improved ventilation, thus maintaining the ideal atmosphere for plant cultivation.
Sunshade System
1. External Sunshade System: The external sunshade system features a sunshade net positioned atop the greenhouse. Operated either automatically or manually, it adapts to varying light intensities and indoor temperatures through electric control. This ingenious system effectively diminishes solar influx, curbing heat penetration, and preventing excessive temperature rise during scorching summer days, thereby shielding plants from intense sunlight damage.
2. Internal Sunshade System: Installed inside the greenhouse, this system not only offers shading and cooling advantages but also aids in nocturnal heat retention. By reflecting portions of incoming sunlight, it reduces heat absorption and allows for controlled light distribution within the greenhouse, facilitating a nurturing environment for plant growth.
Irrigation System
1. Drip Irrigation System: Drip irrigation ranks among the most prevalent techniques in glass greenhouses. It efficiently channels water through pipes to individual drippers located near plant roots, ensuring a slow and precise water transfer. This method curtails water evaporation and wastage, while simultaneously allowing fertilizer to be dissolved in the water, thus providing accurate nutrient delivery to plants.
2. Micro-Sprinkler Irrigation System: Featuring sprinkler heads positioned atop the greenhouse or at an elevated height above the plants, this system dispenses water in fine droplets. It significantly enhances air humidity, ideal for plants demanding high moisture levels. Additionally, it covers expansive areas, efficiently irrigating multiple plants simultaneously.
Heating System
1. Hot Water Heating System: Utilizing boilers and allied equipment, this system heats water, which then circulates through pipes laid on the ground or within the greenhouse. The evenly distributed heat elevates indoor temperatures. Moreover, the system allows for easy temperature regulation, with waste heat being repurposed for auxiliary operations, such as hot water irrigation.
2. Hot Air Heating System: This system employs hot air fans to circulate warmed air within the greenhouse, offering rapid heating. Its flexible design permits adjusting the air outlet's position and angle, ensuring a balanced and efficient distribution of warmth throughout the space.
Control System
The intelligent control system is pivotal to a glass greenhouse, seamlessly automating the monitoring and regulation of key environmental parameters, including temperature, humidity, light, and ventilation. Sensors, such as those detecting temperature, humidity, and light, gather comprehensive data, which is relayed to the central controller. This controller, adhering to predefined parameters, autonomously adjusts the operational status of ventilation, shading, irrigation, and heating equipment, thus fostering an optimal environment for plant development.
