Description

Technical Field

[0001] This invention relates to the field of greenhouse cultivation technology, specifically to an intelligent vacuum glass thermoelectric greenhouse. Background Technology

[0002] Glass greenhouses are a new type of facility for modern seed and seedling cultivation. Compared with traditional greenhouse cultivation, glass greenhouse cultivation is not subject to seasonal and climate changes. By controlling light, temperature and humidity, it can ensure high germination rate, high survival rate and high uniformity.

[0003] Traditional glass greenhouses, while possessing excellent light transmission, resilience to harsh weather, and the capacity to support fully automated systems such as internal and external shading, ventilation, integrated water and fertilizer systems, and supplemental lighting, suffer from inferior insulation performance compared to plastic film. This results in significant energy consumption for heating in winter. To address this energy consumption issue, current technology proposes using vacuum glass as the roof and side covering material. The excellent insulation properties of vacuum glass can drastically reduce greenhouse energy consumption, and when combined with solar photovoltaic panels for power generation, energy savings can be achieved. However, while vacuum glass greenhouses offer significant insulation and energy-saving effects in winter, they can lead to excessively high indoor temperatures and humidity in summer (although a vacuum blocks heat conduction and convection, it lacks...). In some cases, solar panels cannot block solar heat radiation, resulting in slow heat dissipation and further amplification by solar radiation. This necessitates the use of a wet curtain and fan system to expel the heated air from the greenhouse, removing the radiant heat. Simultaneously, an air conditioning system is required to maintain a suitable temperature for seedling cultivation, further increasing energy consumption. Furthermore, to avoid obstructing sunlight within the greenhouse, photovoltaic panels are typically installed only in non-light-transmitting areas of the roof (such as gutters or ridges) or on open ground around the greenhouse. This limited installation area restricts total power generation. In practice, this portion of the electricity generated is primarily used for nighttime temperature maintenance, failing to fully power high-power equipment such as large fans, water pumps, and air conditioning compressors, thus requiring an additional energy storage system.

[0004] In view of the above, in order to overcome the above technical problems, the present invention designs an intelligent vacuum glass thermoelectric greenhouse. Summary of the Invention

[0005] This invention provides an intelligent vacuum glass thermoelectric greenhouse, which solves the problems of high energy consumption for heating and cooling in summer and winter and the inability of traditional solar photovoltaic panels to effectively maintain the temperature control system. By integrating a semi-transparent perovskite solar cell layer on the outer glass substrate, a balance between efficient power generation and crop light transmission is achieved. A Low-E film is set on the vacuum side of the inner glass substrate, and its nano-silver layer serves as an active heat source. Combined with the vacuum layer, efficient unidirectional heating and insulation are achieved. At the same time, microfluidic channels are also opened in the inner glass substrate to use collected rainwater for efficient active cooling and optimized light scattering of the greenhouse, thereby improving the quality of seed and seedling cultivation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An intelligent vacuum glass thermoelectric greenhouse includes an installation frame; it also includes a vacuum glass panel, a collection system, a circulation system, and a control system; the vacuum glass panel is arranged on the top and around the installation frame, and the vacuum glass panel includes an outer glass substrate, an inner glass substrate, and a vacuum layer disposed between the outer and inner glass substrates; the collection system is connected to the vacuum glass panel on top of the installation frame; the circulation system is connected to the collection system and is used to drive rainwater in the collection system to circulate within the vacuum glass panel; the control system is electrically connected to the circulation system and is used to control the start and stop of the circulation system.

[0008] Preferably, a semi-transparent solar cell layer is integrated on the outer glass substrate; the inner glass substrate is provided with a Low-E film on the side facing the outer glass substrate, which has high transmittance for solar radiation with wavelengths in the range of 0.4 to 2.5 micrometers and high reflectivity for long-wave thermal radiation with wavelengths greater than 2.5 micrometers.

[0009] In the above scheme, the semi-transparent solar cell layer integrated on the outer glass substrate can absorb solar energy to generate electricity, while the inner glass substrate is equipped with a Low-E film. On the one hand, the semi-transparent solar cell layer can absorb heat, and the semi-transparent photovoltaic layer can increase the laying area and increase the power generation. On the other hand, the Low-E film on the inner glass substrate can further improve the heat preservation effect of the vacuum glass plate. It has high transmittance for solar radiation with wavelengths in the range of 0.4 to 2.5 micrometers, which can completely cover the visible light (0.4 to 0.7 micrometers) necessary for plant photosynthesis, ensuring that energy and light energy enter the greenhouse to the maximum extent. The wavelength greater than 2.5 micrometers is the long-wave infrared band in which objects at normal earth temperature (such as the ground and plants) emit heat. It has high reflectivity for long-wave thermal radiation with wavelengths greater than 2.5 micrometers, which can lock heat in the greenhouse.

[0010] Preferably, the Low-E film is a multilayer composite structure in which a dielectric layer encapsulates a silver nanolayer; the silver nanolayer is electrically connected to the control system.

[0011] In the above scheme, the middle layer of the Low-E film is a nano-silver layer, which can achieve high infrared reflectivity and high visible light transmittance. By applying voltage to both ends of the nano-silver layer through the control system, Joule heating can be generated by utilizing the conductivity of the silver layer, thus serving as an active heat source. The passive heat insulation and active heating functions are integrated into a single film layer, resulting in a simpler structure, lower cost, and higher reliability. In addition, since the nano-silver layer acts as a heat source, it is located between the vacuum layer and the inner glass substrate. The heat it generates will be forcibly transferred unidirectionally into the greenhouse. Furthermore, its high reflectivity to long-wave heat radiation greater than 2.5 micrometers can effectively lock the heat inside the greenhouse, thereby ensuring heating efficiency.

[0012] Preferably, the inner glass substrate also has microfluidic channels.

[0013] In the above scheme, rainwater collected by the collection system can flow within the inner glass substrate through microfluidic channels. In summer, forced convection heat transfer cools the inner glass substrate, regulating the internal environment of the greenhouse and thus solving the problem of temperature rise caused by short-wave solar radiation in summer. This allows the vacuum glass panel to simultaneously possess active heating and efficient cooling capabilities. Furthermore, when strong direct sunlight in summer passes through the glass substrate and enters the microfluidic channels containing flowing liquid, the light is refracted and reflected at multiple glass-liquid-glass interfaces. This optical scattering effect can transform highly directional collimated beams into more diffused light with a more diffuse angle. This not only effectively avoids strong light scorching of the leaves at the top of the crop canopy, but also allows light to be transmitted more evenly to the middle and lower parts of the plant, significantly improving the light energy utilization efficiency of the entire canopy. This optimizes the light environment for seedlings while achieving cooling, which helps to improve the quality of seedling cultivation. In order to reduce manufacturing costs and improve temperature control efficiency, Low-E films need to be installed on the vacuum glass plates at the top and around the frame, and microfluidic channels are only opened on the top vacuum glass plate.

[0014] Preferably, the semi-transparent solar cell layer is a perovskite solar cell layer.

[0015] In the above scheme, perovskite material is used as the photovoltaic layer. Perovskite cells have adjustable spectral response characteristics and a semi-transparent morphology. They can selectively absorb part of the spectrum (such as ultraviolet light and part of visible light) to generate electricity, while allowing the core spectrum (mainly red and blue light) required for plant photosynthesis to pass through efficiently. This achieves a balance between power generation and ensuring the light needs of plants, solving the problem of traditional crystalline silicon photovoltaic panels causing severe shading and affecting crop yield in greenhouse applications. Furthermore, perovskite still has high power generation efficiency under weak light conditions such as cloudy days or early morning and evening, improving the energy self-sufficiency of greenhouses under undesirable weather conditions.

[0016] Preferably, the collection system includes a top trench, a liquid storage side trench, and a connecting pipe; the top trench is located on the top of the mounting frame and connected to the upper edge of the top vacuum glass plate on both sides, and a guide hole communicating with a microfluidic channel is opened at the connection position between the top trench and the inner glass substrate; the liquid storage side trench is connected to the lower edge of the top vacuum glass plate and the upper edge of the vacuum glass plates around the perimeter; the connecting pipe is connected between the liquid storage side trench and the top trench.

[0017] The above scheme constructs a closed-loop circulation and distribution path for the cooling liquid (rainwater) using gravity assistance. When it rains, rainwater from the top gutter and the surface of the vacuum glass plate will flow to the storage gutter for storage. When the indoor temperature is higher than the cooling threshold, under the control of the circulation and control systems, the rainwater will be pumped from the storage gutter through the connecting pipe to the top gutter, and then flow back to the storage gutter through the microfluidic channel under gravity to complete the heat exchange cycle. In summer, in order to further improve the heat exchange and energy-saving effects, the temperature of the rainwater in the storage gutter can be monitored. When the temperature rises after heat exchange is completed, it is first stored in the storage gutter. When the temperature drops at night, the rainwater with residual heat can be circulated again to enhance the heat preservation effect inside the greenhouse and cool the rainwater back to a low temperature.

[0018] Preferably, the circulation system includes a temperature sensor and a circulation pump; the temperature sensor is disposed inside the vacuum glass plate on the top layer; the circulation pump is disposed at the connection point between the liquid storage ditch and the connecting pipe.

[0019] In the above scheme, when the temperature sensor detects that the temperature inside the greenhouse is higher than the preset cooling threshold, the control system will start the circulation pump, so that the liquid (rainwater) in the storage ditch flows to the top ditch through the connecting pipe, and then flows back to the storage ditch under the action of gravity, completing the circulation. During the circulation process, the liquid can absorb heat and prevent the indoor temperature from continuing to rise.

[0020] Preferably, a heat insulation layer is provided inside the liquid storage trench, and a collection filter port is provided at the connection position between the liquid storage trench and the top vacuum glass plate.

[0021] In the above scheme, by adding a heat insulation layer inside the liquid storage ditch, it is ensured that the collected rainwater will not heat up due to external solar radiation or high ambient temperature, thereby ensuring its cooling efficiency and guaranteeing the cooling performance of the entire greenhouse; at the same time, the set collection filter can effectively filter out impurities such as leaves and dust carried in the rainwater, preventing them from entering the microfluidic channel and causing blockage, thus improving the long-term operational reliability and stability of the system.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. Compared to existing vacuum glass greenhouses, this invention achieves active temperature control by creating microfluidic channels within the vacuum glass panels and linking them with a collection system consisting of top grooves, liquid storage side grooves, and connecting pipes. Rainwater collected in the top and side grooves is used as a cooling medium, circulated within the microfluidic channels by a circulating pump. This forced convection heat transfer directly cools the inner glass substrate, preventing excessively high internal temperatures caused by short-wave solar radiation in summer. Simultaneously, the flowing liquid in the microfluidic channels causes sunlight to refract and reflect at multiple glass-liquid-glass interfaces, converting highly directional collimated beams into more diffused light with a more diffuse angle. This effectively avoids sunburn on the top leaves of crops and allows light to penetrate more evenly to the lower and middle parts of the plant, thereby improving seedling quality.

[0024] 2. This invention designs the Low-E film as a composite structure with a dielectric layer sandwiching a nano-silver layer, placing it on the side of the inner glass substrate facing the outer glass substrate. Utilizing the Low-E film's high reflectivity for long-wavelength thermal radiation greater than 2.5 micrometers and its high transmittance for solar radiation from 0.4 to 2.5 micrometers, passive heat preservation performance is improved while ensuring effective photosynthesis of seedlings. The electrical connection between the control system and the nano-silver layer is used to generate Joule heating through its conductivity, making the Low-E film itself an active heat source. The nano-silver layer, acting as the heat source, is located between the vacuum layer and the inner glass substrate. The generated heat is forcibly transferred unidirectionally into the greenhouse by the high reflectivity of the vacuum layer and the Low-E film itself, further improving the greenhouse heating efficiency.

[0025] 3. This invention uses a perovskite solar cell layer as a semi-transparent solar cell layer integrated on an outer glass substrate. Unlike traditional materials that completely block light, the perovskite solar cell layer has unique spectral selectivity, which can selectively absorb part of the spectrum to generate electricity, while ensuring efficient transmission of the core spectrum (mainly red and blue light) that is crucial for plant photosynthesis. This achieves a balance between power generation and ensuring the light requirements of plants. In addition, the perovskite solar cell layer still maintains high power generation efficiency under weak light conditions such as cloudy days or early morning and evening, which significantly improves the energy self-sufficiency of the thermal power greenhouse under undesirable weather conditions.

[0036] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0037] Please see Figures 1 to 8 This invention provides an intelligent vacuum glass thermoelectric greenhouse, the technical solution of which is as follows:

[0038] As a specific embodiment of the present invention, refer to Figure 1 , Figure 2 and Figure 3 A smart vacuum glass thermal greenhouse includes a frame 1 made of hot-dip galvanized steel. This material achieves excellent corrosion and rust resistance by immersing the steel structural components in a molten zinc bath, resulting in a thick and dense zinc layer on the surface. In the high-humidity environment of the greenhouse, the hot-dip galvanized frame resists moisture erosion, ensuring structural stability and load-bearing capacity for decades, requiring minimal maintenance and reducing long-term operating costs. The greenhouse also includes a vacuum glass panel 2, a collection system 3, a circulation system 4, and a control system 5. The vacuum glass panel 2 is arranged on top and around the frame 1, and includes an outer glass substrate 21, an inner glass substrate 22, and a vacuum layer 23 between the outer and inner glass substrates. The collection system 3 is connected to the vacuum glass panel 2 at the top of the frame 1. The circulation system 4 is connected to the collection system 3 and drives the rainwater within the collection system 3 to circulate within the vacuum glass panel 2. The control system 5 is electrically connected to the circulation system 4 and controls the start and stop of the circulation system 4. Figure 1 For ease of demonstration, control system 5 is shown outside the greenhouse; in actual use, it is usually installed inside the greenhouse.

[0039] As a specific embodiment of the present invention, refer to Figure 1 , Figure 2 and Figure 3 A semi-transparent solar cell layer 211 is integrated on the outer glass substrate 21; a Low-E film 221 with high transmittance for solar radiation with wavelengths in the range of 0.4 to 2.5 micrometers and high reflectivity for long-wave thermal radiation with wavelengths greater than 2.5 micrometers is disposed on the side of the inner glass substrate 22 facing the outer glass substrate 21. The semi-transparent solar cell layer 211 integrated on the outer glass substrate 21 can absorb solar energy to generate electricity. The inner glass substrate 22 is provided with a Low-E film 221. On the one hand, the semi-transparent solar cell layer 211 can absorb heat, and the semi-transparent photovoltaic layer can increase the laying area and increase the power generation. On the other hand, the Low-E film 221 on the inner glass substrate 22 can further improve the heat preservation effect of the vacuum glass plate 2. It has high transmittance for solar radiation with wavelengths in the range of 0.4 to 2.5 micrometers, which can completely cover the visible light (0.4 to 0.7 micrometers) necessary for plant photosynthesis, ensuring that energy and light energy enter the greenhouse to the maximum extent. The wavelength greater than 2.5 micrometers is the long-wave infrared band in which objects at normal earth temperature (such as the ground and plants) emit heat. It has high reflectivity for long-wave thermal radiation with wavelengths greater than 2.5 micrometers, which can lock heat in the greenhouse.

[0040] As a specific embodiment of the present invention, refer to Figure 1 , Figure 2 and Figure 3 The Low-E film 221 is a multilayer composite structure consisting of a dielectric layer 2211 sandwiching a nano-silver layer 2212; the nano-silver layer 2212 is electrically connected to the control system 5. The middle layer of the Low-E film 221, the nano-silver layer 2212, can achieve high infrared reflectivity and high visible light transmittance. By applying voltage to both ends of the nano-silver layer 2212 through the control system 5, Joule heating can be generated using the conductivity of the silver layer, thus serving as an active heat source. This integrates passive insulation and active heating functions into a single film layer, resulting in a simpler structure, lower cost, and higher reliability. In addition, since the nano-silver layer 2212 acts as a heat source, located between the vacuum layer 23 and the inner glass substrate 22, the heat it generates will be forcibly transferred unidirectionally into the greenhouse. Furthermore, its high reflectivity to long-wave heat radiation greater than 2.5 micrometers effectively locks the heat inside the greenhouse, thereby ensuring heating efficiency.

[0041] As a specific embodiment of the present invention, refer to Figure 2 , Figure 3 , Figure 4 and Figure 7 The inner glass substrate 22 also has microfluidic channels 222. These microfluidic channels 222 allow rainwater collected by the collection system 3 to flow within the inner glass substrate 22. In summer, forced convection heat transfer cools the inner glass substrate 22, regulating the internal environment of the greenhouse and thus solving the problem of temperature rise caused by short-wave solar radiation in summer. This allows the vacuum glass panel 2 to simultaneously possess active heating and efficient cooling capabilities. Furthermore, when strong direct sunlight passes through the glass substrate and enters the microfluidic channels 222 containing flowing liquid, the light is refracted and reflected at multiple glass-liquid-glass interfaces. Optical scattering effect can convert highly directional collimated beams into diffused light with a more gentle angle, which not only effectively avoids strong light scorching of the leaves at the top of the crop canopy, but also allows light to be transmitted more evenly to the middle and lower parts of the plant, significantly improving the light energy utilization efficiency of the entire canopy. Thus, while achieving cooling, it optimizes the light environment of the crop, which helps to improve yield and quality. In order to reduce manufacturing costs and improve temperature control efficiency, Low-E films 221 need to be installed on the top and all four sides of the vacuum glass plates 2 of the frame 1, and microfluidic channels 222 are only opened on the top vacuum glass plate 2.

[0042] As a specific embodiment of the present invention, refer to Figure 3The semi-transparent solar cell layer 211 is a perovskite solar cell layer. Using perovskite material as the photovoltaic layer, the perovskite cell has adjustable spectral response characteristics and a semi-transparent morphology. It can selectively absorb part of the spectrum (such as ultraviolet light and part of visible light) to generate electricity, while allowing the core spectrum (mainly red and blue light) required for plant photosynthesis to pass through efficiently. This achieves a balance between power generation and ensuring the light requirements of plants, solving the problem of severe shading and reduced crop yield caused by traditional crystalline silicon photovoltaic panels in greenhouse applications. Furthermore, perovskite still has high power generation efficiency under weak light conditions such as cloudy days or early morning / evening, improving the greenhouse's energy self-sufficiency under less than ideal weather conditions.

[0043] As a specific embodiment of the present invention, refer to Figure 4 , Figure 5 , Figure 7 and Figure 8 The collection system 3 includes a top groove 31, a liquid storage side groove 32, and a connecting pipe 33. The top groove 31 is located on the top of the mounting frame 1 and is connected to the upper edge of the top vacuum glass plate 2 on both sides. A guide hole 311 communicating with the microfluidic channel 222 is opened at the connection position between the top groove 31 and the inner glass substrate 22. The liquid storage side groove 32 is connected to the lower edge of the top vacuum glass plate 2 and the upper edge of the vacuum glass plates 2 around the perimeter. The connecting pipe 33 is connected between the liquid storage side groove 32 and the top groove 31. A closed-loop circulation and distribution path for the cooling liquid (rainwater) using gravity assistance was constructed. When it rains, the rainwater on the surface of the top ditch 31 and the vacuum glass plate 2 will flow to the storage ditch 32 for storage. When the indoor temperature is higher than the cooling threshold, under the control of the circulation system 4 and the control system 5, the rainwater will be pumped from the storage ditch 32 to the top ditch 31 through the connecting pipe 33, and then flow back to the storage ditch 32 under the action of gravity through the microfluidic channel 222 to complete the heat exchange cycle. In summer, in order to further improve the heat exchange and energy-saving effect, the temperature of the rainwater in the storage ditch 32 can be monitored. When the temperature rises after the heat exchange is completed, it is first stored in the storage ditch 32. When the temperature drops at night, the rainwater with residual heat can be circulated again to enhance the heat preservation effect inside the greenhouse and also to cool the rainwater back to a low temperature state.

[0044] As a specific embodiment of the present invention, refer to Figure 2 , Figure 4 , Figure 7 and Figure 8The circulation system 4 includes a temperature sensor 41 and a circulation pump 42. The temperature sensor 41 is located inside the vacuum glass plate 2 at the top layer. The circulation pump 42 is located at the connection point between the liquid storage ditch 32 and the connecting pipe 33. When the temperature sensor 41 detects that the temperature inside the greenhouse is higher than the preset cooling threshold, the control system 5 will start the circulation pump 42, causing the liquid (rainwater) in the liquid storage ditch 32 to flow to the top ditch 31 through the connecting pipe 33, and then flow back to the liquid storage ditch 32 under gravity (the liquid storage ditch 32 is connected to the microfluidic channel 222), completing the circulation. During the circulation process, the liquid can absorb heat to prevent the indoor temperature from continuing to rise.

[0045] The entire system's operating logic is uniformly scheduled by control system 5, as follows:

[0046] Summer Cooling Mode: When the temperature sensor 41 detects that the indoor temperature exceeds the preset cooling threshold, the control system 5 issues a command to start the circulation pump 42. The low-temperature rainwater stored in the liquid storage side ditch 32 is pumped and lifted to the top ditch 31 via the connecting pipe 33. In the top ditch 31, the rainwater enters the microfluidic channel 222 through the guide hole 311. Under the action of gravity, the rainwater flows from top to bottom in the microfluidic channel 222, and performs efficient forced convection heat exchange with the inner glass substrate 22, absorbing indoor heat and preventing the indoor temperature from rising further. After the heat exchange is completed, the heated rainwater flows out from the lower end of the microfluidic channel 222 and returns to the liquid storage side ditch 32. This process is repeated until the indoor temperature drops to a safe range. At the same time, strong light passes through the flowing liquid and is scattered into soft diffused light, optimizing the lighting environment.

[0047] Winter heating mode: When the temperature sensor 41 detects that the indoor temperature is lower than the preset heating threshold, the control system 5 will apply voltage to the nano-silver layer 2212 of the Low-E film 221 to make it start to heat up and provide precise indoor heating.

[0048] As a specific embodiment of the present invention, refer to Figure 8 The liquid storage ditch 32 is equipped with a heat insulation layer 321, and a collection filter 322 is provided at the connection between the liquid storage ditch 32 and the top vacuum glass plate 2. By adding a heat insulation layer 321 to the liquid storage ditch 32, it is ensured that the collected rainwater will not heat up due to external solar radiation or high ambient temperature, thereby ensuring its cooling efficiency and guaranteeing the cooling performance of the entire greenhouse. At the same time, the collection filter 322 can effectively filter out impurities such as leaves and dust carried in the rainwater, preventing them from entering the microfluidic channel 222 and causing blockage, thus improving the long-term operational reliability and stability of the system.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as defined by the appended claims and their equivalents.
