Description

Technical Field

[0001] This invention relates to the field of architectural decoration technology, specifically to a double-layer glass curtain wall design structure with interlayer gas-liquid mixing circulation and temperature regulation. Background Technology

[0002] The built environment is a fundamental condition for ensuring the quality of human life. At the same time, people's demands for maintaining and improving the quality of their living and working environments make the energy consumed therea major factor contributing to energy shortages. Currently, energy consumption for maintaining and improving the built environment accounts for more than 20% of total societal energy consumption. Large public buildings, especially airport terminals and train stations, not only require relatively high indoor environmental quality but also, due to their glass curtain wall designs, demand excellent transparency and a high window-to-wall ratio, resulting in significant energy consumption. Therefore, the need for advancements in energy-saving technologies is even more urgent. Thus, to achieve sustainable social development, continuous improvement of building energy-saving technologies is imperative.

[0003] However, most airport terminals currently use large-area low-emissivity glass curtain wall structures. In hot summer regions with long hours of sunshine, the simple thermal barrier or heat transfer delay technology of common glass curtain walls, which rely on heat insulation, heat conduction materials, and internal airflow heat transfer design, is still difficult to continuously prevent a large amount of radiant heat from entering the building space. Under relatively extreme temperatures such as summer and winter, the indoor temperature regulation efficiency and thermal barrier performance are poor. Secondly, due to the irregular movement of fluids inside the double-glazed windows, the unstable flow rate and velocity of the fluid can easily cause overall circulation disturbance of the heat conduction layer, and affect the overall sound insulation performance of the wall system. Furthermore, the curtain wall is large in size, and the heat dissipation medium in the fluid heat conduction layer is lost quickly, resulting in high resource consumption and low resource utilization. Summary of the Invention

[0004] The purpose of this invention is to address the problems of poor thermal insulation, thermal conductivity, and indoor temperature regulation efficiency of current glass curtain wall structures when used in large areas, which cannot meet the usage requirements of different seasons and environments, as well as the problems of fluid disturbance in the internal heat-conducting layer affecting thermal conductivity and sound insulation performance. Therefore, this invention provides a double-layer glass curtain wall design structure with interlayer gas-liquid mixing circulation temperature regulation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a double-layer glass curtain wall design structure with interlayer gas-liquid mixing circulation and temperature regulation, comprising:

[0006] Outer glass plate;

[0007] The outer building base includes an upper floor slab, a lower floor slab, and the side walls of the floor. The edge of the outer glass panel is sealed and fitted onto the upper floor slab, the lower floor slab, and the side walls of the floor.

[0008] Inner glass panel;

[0009] The inner building base layer is connected to the outer building base layer at its bottom and sides. A fence is provided on the side of the bottom facing the outer glass panel. The inner glass panel is sealed between the fence and the inner building base layer. A convection channel is formed between the outer glass panel, the inner building base layer, and the inner glass panel. A first ventilation opening is provided on the fence, and at least one second ventilation opening is provided on the inner building base layer.

[0010] A nozzle assembly for supplying air or water within the convection channel; a fan is installed in the convection channel between the top of the outer building base and the top of the inner building base.

[0011] A roller assembly, rotatably mounted at the bottom of the convection channel via a rotating shaft, has several auxiliary convection components spaced axially and circumferentially on its surface. A water tank is positioned below the bottom surface of the first vent in the convection channel, and hot water is injected into the water tank. A drainage assembly is installed at the bottom of the water tank on the lower floor slab. The drainage assembly and the nozzle assembly are connected to an external drive mechanism via a media conduit. The top of the nozzle assembly is connected to the outlet of a water storage tank via a media conduit, and a water pump is mounted on this section of the media conduit. The inlet of the water storage tank is connected to the drainage assembly via a media conduit.

[0012] The reservoir is equipped with several detachable modules, including ultraviolet germicidal lamps, ozone generators, sterilization devices, and filter components arranged sequentially along the water flow direction inside the reservoir.

[0013] A drain valve is installed on the drainage assembly. This drain valve is a solenoid valve that is associated with sensors such as liquid level sensors and temperature sensors in the water tank.

[0014] In addition, a T-shaped connector is provided in part of the medium conduit between the water storage tank and the nozzle assembly, and an air supply branch extends therefrom. A passage switching valve is provided on the T-shaped connector, and an air pump is connected to the air supply branch.

[0015] As a further description of the above technical solution:

[0016] A first ventilation mesh plate is provided on the outer side of the first ventilation opening facing the roller assembly, and a second ventilation mesh plate is provided on the second ventilation opening.

[0017] As a further description of the above technical solution:

[0018] The nozzle assembly has several spray nozzles positioned directly above the outer and inner glass plates.

[0019] As a further description of the above technical solution:

[0020] The angle between the water nozzle and the facade of the outer and inner glass panels is 0-10°.

[0021] As a further description of the above technical solution:

[0022] The auxiliary convection component has concave curved grooves on both ends.

[0023] As a further description of the above technical solution:

[0024] A flow stabilizer is installed between the side walls of the floor, and the flow stabilizer covers the roller assembly. The flow stabilizer has a first opening directly below the nozzle assembly.

[0025] As a further description of the above technical solution:

[0026] The first opening gradually contracts and converges from the inside out.

[0027] As a further description of the above technical solution:

[0028] The flow stabilizer extends into the water tank on the side of the flow stabilizer closest to the first vent. A second opening is provided on the flow stabilizer on this side, directly opposite the first vent, and the size of the second opening gradually increases from the inside to the outside.

[0029] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0030] 1. This invention utilizes the airflow circulation effect of the double-layered glass to assist in thermal barrier, while designing a uniform water curtain flow to improve the heat transfer capacity of the interlayer medium, thereby achieving rapid temperature regulation and thermal barrier against the external environment. The total heat transmittance is less than 0.02, which can meet the needs of different usage environments and different usage seasons, and reduce energy consumption.

[0031] 2. The double-glazed curtain wall allows for the inflow of air and water through the interlayer, enabling rapid adjustment of indoor temperature in summer and winter, and temperature control of the glass and interlayer. This reduces the impact of high or low external temperatures on the indoor environment, lowers the energy consumption of indoor cooling or heating systems, and the air and water are recycled, which aligns with the green, ecological, and sustainable design concept.

[0032] 3. The nozzle assembly and the roller assembly associated with the water and airflow were specifically designed. In summer and high-temperature environments, when the above structure is used, indoor hot air is led out of the room through the first vent and into the convection channel. The cooling water sprayed from the nozzle assembly flows downwards along the inner and outer glass panels on both sides, cooling the glass and the led-out hot airflow, thus reducing the temperature of the double-glazed curtain wall. The hot water at the bottom of the convection channel cools and controls the temperature of the outer glass panel and interlayer. The downward flow of water impacts the auxiliary convection assembly, causing the roller assembly to rotate (which can be driven by a motor). The auxiliary convection assembly also fans and accelerates the airflow at the first vent, improving the efficiency of hot air extraction. Simultaneously, it agitates the hot water to ensure its thermal conductivity. When used in winter or low-temperature environments, hot air is introduced into the relatively high-temperature convection channel through the nozzle assembly, and then carried into the room through the first vent for initial heating. The hot water at the bottom of the convection channel melts and releases heat, appropriately increasing the temperature inside the convection channel. The roller assembly resumes its rolling function to guide the airflow. Then, the hot airflow reverses, and the nozzle assembly sprays hot water out, allowing it to flow down the glass surface. This, combined with the hot airflow from the room, heats the glass, thereby regulating the temperature of the glass curtain wall and preventing fogging in winter. The falling water flow drives the roller assembly to accelerate convection, and the relatively high-temperature hot water heats the outer glass panel, ensuring a high temperature in the convection channel to achieve thermal insulation between the indoor and outdoor areas. This enables the double-glazed curtain wall and rapid temperature regulation of the interior. Attached Figure Description

[0043] Example 1:

[0044] Please see Figure 1-5 This invention provides a technical solution: a double-glazed curtain wall design structure with interlayer gas-liquid mixing circulation and temperature regulation, comprising:

[0045] Outer glass plate 1;

[0046] The outer building base includes an upper floor slab 2, a lower floor slab 3, and the side walls of the floor. The edge of the outer glass panel 1 is sealed and fitted onto the upper floor slab 2, the lower floor slab 3, and the side walls of the floor.

[0047] Inner glass plate 5;

[0048] The inner building base 4 is connected to the outer building base 4 at its bottom and sides. A fence 41 is provided on the side of the bottom facing the outer glass panel 1. The inner glass panel 5 is sealed between the fence 41 and the inner building base 4. A convection channel 6 is formed between the outer glass panel 1, the inner building base 4, and the inner glass panel 5. A first ventilation opening 42 is provided on the fence 41, and at least one second ventilation opening 44 is provided on the inner building base 4.

[0049] The nozzle assembly 7 is used to supply air or water within the convection channel 6; in this embodiment, a fan 100 is installed in the convection channel 6 between the top of the outer building base layer and the inner building base layer 4.

[0050] A roller assembly 8 is rotatably mounted at the bottom of the convection channel 6 via a rotating shaft 81. Several auxiliary convection components 82 are spaced axially and circumferentially on its surface. A water tank is arranged below the bottom surface of the first vent 42 in the convection channel 6. Hot water is injected into the water tank. A drainage assembly 31 is installed at the bottom of the water tank on the lower floor slab 3. The drainage assembly 31 and the nozzle assembly 7 are connected to an external drive mechanism via a media conduit 71. In this embodiment, the top of the nozzle assembly 7 is connected to the outlet of the water storage tank 200 via the media conduit 71. A water pump 300 is installed on this section of the media conduit 71. The inlet of the water storage tank 200 is connected to the drainage assembly 31 via the media conduit 71.

[0051] The water storage tank 200 is equipped with several detachable modules, including ultraviolet germicidal lamps, ozone generators, sterilization devices, and filter components arranged sequentially along the water flow direction inside the water storage tank 200.

[0052] A drain valve is provided on the drain assembly 31. This drain valve is a solenoid valve that is associated with sensors such as liquid level sensor and temperature sensor in the water tank.

[0053] In addition, a T-shaped connector is provided in part of the medium conduit 71 between the water storage tank 200 and the nozzle assembly 7, and an air supply branch is extended therefrom. A passage switching valve 500 is provided on the T-shaped connector, and an air pump 400 is connected to the air supply branch.

[0054] The double-glazed curtain wall of this invention allows for rapid adjustment of indoor temperature in summer and winter through the airflow and water flow in the interlayer, and enables temperature control of the glass and interlayer, reducing the impact of high or low external environments on the indoor environment and lowering the energy consumption of indoor cooling or heating systems.

[0055] When used in summer or high-temperature environments, such as Figure 3At this time, the indoor temperature is higher than the outdoor temperature. The fan 100 and the indoor cooling system are running, so that the hot air inside is discharged through the first vent 42. The water pump 300 pumps the cooling water in the water storage tank 200 to the nozzle assembly 7. The sprayed cooling water flows down along the inner and outer glass plates on both sides to cool the glass and the discharged hot airflow, thereby reducing the temperature of the double-layer glass curtain wall. The hot water body at the bottom of the convection channel 6 cools and controls the temperature of the outer glass plate 1 and the interlayer. The water flow moves down and impacts the auxiliary convection assembly 82, causing the roller assembly 8 to rotate (which can be driven by a motor). With the help of the auxiliary convection assembly 82, the airflow at the first vent 42 is fanned and accelerated to improve the efficiency of hot air discharge. At the same time, the hot water body is stirred to ensure its heat conduction efficiency. If the temperature or water level is too high, the hot water body is discharged through the drain assembly 31 into the water storage tank 200, where it is sterilized, filtered, cooled, and then recycled.

[0056] When used in winter or low-temperature environments, such as Figure 4 At this time, the indoor temperature is lower than the outdoor temperature. The air pump 400 directs hot airflow through the nozzle assembly 7 into the relatively warm convection channel 6, and then carries it into the room through the first vent 42 for initial heating. The hot water at the bottom of the convection channel 6 melts and releases heat, appropriately increasing the temperature inside the convection channel 6. At this time, the hot water can be low-temperature, highly soluble brine with a large heat release upon melting. The roller assembly 8 resumes its rolling function, guiding the airflow. Then, as... Figure 5 The flow switching valve 500 switches the state of the medium conduit 71, reverses the hot air flow, and the nozzle assembly 7 sprays hot water out, allowing it to flow down the glass surface. This, combined with the hot air flow from the room, heats the glass, thereby regulating the temperature of the glass curtain wall and preventing fogging in winter. The falling water flow drives the roller assembly 8 to accelerate convection. The relatively high-temperature hot water body heats the outer glass panel 1, ensuring a high temperature in the convection channel 6 to achieve thermal insulation between the indoor and outdoor spaces. This enables the double-glazed curtain wall and rapid temperature regulation of the indoor space.

[0057] A first ventilation mesh plate 43 is provided on the outer side of the first ventilation opening 42 facing the roller assembly 8, and a second ventilation mesh plate 45 is provided on the second ventilation opening 44.

[0058] The nozzle assembly 7 has several spray nozzles arranged directly above the outer glass plate 1 and the inner glass plate 5 to ensure that the water flows closely to the glass surface and to ensure the glass temperature regulation efficiency.

[0059] Example 2:

[0060] Please see Figure 1-5Based on the above embodiment one, preferably, the angle between the water nozzle and the facade of the outer glass plate 1 and the inner glass plate 5 is 0-10°, which further ensures the flow of water on the glass surface and its heat conduction efficiency, avoids water spraying and reflection, splashing, and disruption of internal airflow, and prevents insufficient heat conduction between water and glass.

[0061] Example 3:

[0062] Please see Figure 1-5 Based on the above embodiment 1, preferably, the auxiliary convection component 82 is provided with concave curved grooves 83 on both ends. This design improves the impact force of the water flow on the auxiliary convection component 82 and the transmission efficiency of the roller component 8 rolling, and can reduce water splashing, and ensure that the auxiliary convection component 82 on the other side fully entrains the airflow, thus ensuring the efficiency of airflow fanning and acceleration.

[0063] Example 4:

[0064] Please see Figure 1-5 Based on the above embodiment one, preferably, a flow stabilizer 9 is provided between the side walls of the floor. The flow stabilizer 9 covers the roller assembly 8. This design is used to reduce the impact of water flow and roller assembly 8 on airflow. The flow stabilizer 9 is provided with a first opening 91 directly below the nozzle assembly 7. The first opening 91 gradually contracts and converges from the inside to the outside to block the splashed water, further reducing the amount of water splashed out of the flow stabilizer 9 and reducing airflow disturbance.

[0065] Example 5:

[0066] Please see Figure 1-5 Based on the above embodiment four, compared with the design of the flow stabilizer 9 in embodiment four, which blocks the roller assembly 8 on one side of the outer glass plate 1 and opens the other side, it further ensures efficient fanning and acceleration of airflow. Preferably, the flow stabilizer 9 extends into the water tank on the side near the first vent 42. A second opening 92 is provided on the flow stabilizer 9 on this side, directly opposite the first vent 42. The size of the second opening 92 gradually increases from the inside to the outside. The first ventilation mesh plate 43 is tangentially disposed at the roller assembly 8, and the airflow flows along its surface. The above design is used to open the area where the roller assembly 8 efficiently fans and accelerates the airflow, while blocking the area where the airflow is inefficient and inhibits acceleration.

[0067] In summary, due to the adoption of the above technical solutions, the double-glazed curtain wall design structure with interlayer gas-liquid mixing circulation temperature regulation in this embodiment has the following advantages compared with the prior art:

[0068] 1. This invention utilizes the airflow circulation effect of the double-layered glass to assist in thermal barrier, while designing a uniform water curtain flow to improve the heat transfer capacity of the interlayer medium, thereby achieving rapid temperature regulation and thermal barrier against the external environment. The total heat transmittance is less than 0.02, which can meet the needs of different usage environments and different usage seasons, and reduce energy consumption.

[0069] 2. The double-glazed curtain wall allows for the inflow of air and water through the interlayer, enabling rapid adjustment of indoor temperature in summer and winter, and temperature control of the glass and interlayer. This reduces the impact of high or low external temperatures on the indoor environment, lowers the energy consumption of indoor cooling or heating systems, and the air and water are recycled, which aligns with the green, ecological, and sustainable design concept.
