Description

Technical Field

[0001] The present invention belongs to the fields of low-carbon buildings, high-performance variable exterior envelope structures, and digital intelligent control. Specifically, it relates to a low-carbon building exterior envelope system that couples physical structure with digital intelligent control. Background Art

[0002] Intermittent air conditioning systems can effectively reduce energy consumption by properly controlling the air conditioning's operating hours and temperature. Compared to continuously operating air conditioning systems, intermittent air conditioning, combined with intelligent control systems, can precisely adjust and control the system based on factors such as building usage and indoor and outdoor temperatures, achieving optimal energy utilization.

[0003] Intermittent air conditioning reduces greenhouse gas emissions and contributes positively to climate change mitigation. Intermittent air conditioning can participate in electricity demand response programs, adjusting its operating hours and power according to grid demand. This helps balance grid loads, improve power system stability, and promote the integration of renewable energy.

[0004] Low-carbon buildings require a deep integration of high-performance exterior envelope structures and digital, intelligent control. Digital elements are currently accelerating the restructuring of economic and social development, bringing about a technological leap forward in exterior envelope systems to address climate change, functional scenarios, and personalized needs.

[0005] Currently, external enclosure structures utilizing phase change materials and high-performance thermal insulation materials have been developed. However, these systems are immutable or have limited adaptability. These systems are limited to the inherent functional characteristics of passive materials or fixed structures, and lack integration with active control technologies, hindering the potential of digital and intelligent control. Inspired by bionics, animals require both efficient passive thermal insulation structures, such as fur and subcutaneous fat, and the ability to intelligently and proactively adapt their structures to more effectively cope with climate change. For example, dogs extend their tongues to dissipate heat in the summer and curl up to retain warmth in the winter.

[0006] On the other hand, research focused on intelligent control, lacking an efficient, flexible, and adaptable external protection system, has limited control over environmental factors. Control of heat, wind, light, and sound is often limited to just one of these factors, hindering the advantages of digital control. For example, intelligently controlled sunshades only regulate sunlight, but fail to control heat and sound. External protection systems, on the other hand, should generally provide comprehensive control over all these factors. Summary of the Invention

[0007] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a low-carbon building envelope system that couples physical structure with digital intelligent control.

[0008] In order to achieve the above object, the technical solution adopted by the present invention is:

[0009] A low-carbon building envelope system that couples physical structure with digital control comprises a physical structure layer and a digital control layer. The physical structure layer includes lightweight enclosure panels, a rotating shaft, sealing strips, and a telescopic sealing module. The lightweight enclosure panels comprise a non-metallic high-strength thermal insulation frame, high-performance thermal insulation material, a non-metallic high-strength thermal insulation porous frame, sound-absorbing and thermal insulation material, a high-thermal conductivity metal frame, solid-solid phase change material, and a high-sunlight reflective and low-sunlight reflective heat-absorbing surface layer.

[0010] The three pieces of material of the light enclosure panel and their packaging are arranged in a stepped manner to form a sealed circuitous path. The light enclosure panel can rotate about the rotating shaft. Sealing strips are used to press each other between the seams of two adjacent light enclosure panels to ensure the sealing of the gap. A telescopic sealing module is set between the light enclosure panel and the building opening. When the rotation of the light enclosure panel is restricted, the module contracts to ensure the rotation, and extends when it is rotated into place to compact the end of the light enclosure panel and ensure the sealing between the light enclosure panel and the building opening. Multiple light enclosure panels and telescopic sealing modules are combined to form the physical structural layer of the external enclosure system.

[0011] The digital control layer includes a natural room temperature mode when no one is using the intermittent air-conditioning operation state, a rapid cooling and heating mode when it is turned on, a constant temperature mode when used for a long time, a natural cooling and heating mode when outdoor weather conditions are good, a peak shaving mode during peak electricity consumption, and a valley electricity heat and cold storage mode.

[0012] The intelligent control mode of the digital control layer is coupled with the physical properties and structural characteristics of the physical structure layer to achieve energy saving and carbon reduction in building operation under intermittent air-conditioning conditions.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The exterior enclosure system possesses the following characteristics: 1. Comprehensive configuration to address various environmental factors such as heat, wind, light, and sound; 2. Flexible adaptability to adapt to different climate conditions, spatial functions, and individual user requirements; 3. High performance to achieve a healthy and comfortable building interior environment while maintaining energy conservation and low carbon emissions; and 4. Logically clear, multi-mode digital control to seamlessly integrate and fully coordinate the physical structure. This invention possesses these four characteristics, enabling a deep and meaningful coupling between physical structure and digital control. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to deepen the understanding of the present invention, the technical methods and embodiments will be further described in detail below with reference to the accompanying drawings. This part is only used to explain the present invention and does not constitute a limitation on the scope of protection of the present invention.

[0023] The lightweight enclosure consists of three main components: First, a highly reflective, thermally insulating surface layer with a high solar reflectance. Combined with high-performance thermal insulation materials, it effectively blocks solar radiation and thermal radiation from indoor objects, preventing heat exchange between indoor and outdoor, reducing the impact of outdoor temperature fluctuations and solar radiation on the interior, and reducing the loss of heat from the interior. Second, a low-reflective, thermally absorbing surface layer with a high solar heat absorption rate and a very low thermal radiation emission ratio. Combined with a highly thermally conductive metal frame, the phase change material absorbs solar radiation more easily, absorbing and storing heat from the indoor environment, maintaining a more constant indoor temperature and minimizing fluctuations. Third, a central sound insulation layer, encapsulating sound-absorbing rock wool with a frame of a certain perforation rate, works in conjunction with the phase change material, thermal insulation, and frame on both sides to block and absorb noise of varying frequencies. This intermediate sound insulation layer provides both thermal and heat insulation.

[0024] The following specific materials can be selected for each component: 1. High-reflective insulation surface layer: A light-colored, high-reflective insulation coating can be used. 2. Non-metallic, high-strength thermal insulation frame: A glass fiber polyurethane high-strength thermal insulation frame can be used. 2A. Non-metallic, high-strength thermal insulation porous frame: A glass fiber polyurethane high-strength thermal insulation porous frame can be used. 3. High-performance thermal insulation material: A vacuum insulation panel can be used. 4. Sound-absorbing and thermal insulation material: Sound-absorbing rock wool can be used. 5. High-thermal conductivity metal frame: Aluminum can be used. 6. Solid-solid phase change material: The phase change temperature requirements of the present invention can be specifically selected. 7. Low-reflective heat absorption surface layer: A vacuum-coated solar heat absorption coating can be used.

[0025] Actual operation and construction

[0026] like Figure 4 , Figure 5 The lightweight enclosure panels are flipped in the sequence shown in the figure, allowing the insulation and thermal storage materials to be turned inside out. Combined with the expansion and contraction of the telescopic sealing module, they maintain a good sealing performance before and after flipping. The flipping and expansion sequence is achieved using digital intelligent control. Figure 4 is the horizontal direction, Figure 5 That is the vertical direction. Figure 4 is the vertical direction, Figure 5 For horizontal direction. Figure 4 is the tilt direction, Figure 5 For Figure 4 vertical direction. Figure 4 and Figure 5 In the diagram, the adjustment order of the light-duty enclosure is shown: the diagram from left to right is the turning step; from a to e (or other alphabetical order) is the turning (extension) order; the arrow is the turning (extension) direction. Figure 6 , lightweight enclosure panels, based on the combination of climatic conditions and room functions to achieve energy saving and carbon reduction, meet the personalized control of wind, light, sound and other aspects.

[0027] In the following embodiments, all of them are aimed at maintaining indoor comfort and improving energy conservation and carbon reduction effects through flexible comprehensive measures such as insulation and heat storage, ventilation and sealing under intermittent air conditioning operation.

[0028] In the following embodiments, in order to ensure that the phase change material reaches phase change or avoids phase change according to various modes at the corresponding air-conditioning set temperature, the following conditions need to be met: First, the overall enclosure structure of the lightweight enclosure must reach a certain thermal resistance value to ensure that under the local winter and summer meteorological conditions, the temperature difference between the inner surface of the enclosure and the indoor temperature is maintained within a certain range, that is, 3-4°C. Second, the air supply direction of the air outlet is reasonably set according to various modes. There is a certain temperature difference between the air outlet temperature of the air conditioner and the room air-conditioning set temperature, and the temperature difference is generally greater than 3-4°C (the air supply temperature of various air-conditioning equipment is different). When the phase change material is to be used to store energy according to the mode, the phase change material is facing inward, and the air-conditioning outlet is set to supply air to the surface of the phase change material, so that the phase change material accumulates cold and heat through phase change. When the phase change material is to be avoided from storing energy according to the mode, avoid the air-conditioning outlet from supplying air to the surface of the phase change material. For example, if the indoor air conditioning temperature is set at 24°C in winter, if the air conditioning outlet is set to deliver air to the surface of the phase change material, the outlet air temperature is generally 30°C or even higher, causing the surface temperature of the phase change material to reach 26-27°C, causing the phase change material to accumulate heat through phase change. If the air conditioning outlet is prevented from delivering air to the phase change material surface, and the phase change material is heated only by indoor air, the actual surface temperature of the phase change material on the inner surface of the lightweight enclosure is only 20-21°C, and the phase change still cannot be achieved.

[0029] Example 1

[0030] Only one phase change material is used, and the phase change temperature is 23-24°C.

[0031] Air conditioning heating temperatures are generally set at 19-21°C in winter, and 26-27°C in summer. Personnel are encouraged to dress warmly in winter and use slow-speed fans in summer to achieve comfort while reducing heating and cooling loads and achieving energy conservation and carbon reduction.

[0032] When the room is unoccupied, the room is in natural room temperature mode: the phase change material faces inward, the wall panels are closed, and the air conditioner is off. This utilizes the wall panels' excellent insulation, sealing, and heat storage properties to reduce indoor temperature fluctuations. The air conditioner is not on, so no energy is consumed.

[0033] In winter, when a room is switched from unoccupied to occupied, the system switches to rapid heating mode: the phase change material faces outward, and the air conditioner's heating temperature is set to 25-26°C. In this heating mode, the indoor air is rapidly heated. Once the temperature reaches a comfortable level, the heating temperature can be gradually adjusted to 19-21°C. If a person leaves the room for a short period of time, the phase change material rotates back inside, the air conditioner shuts off, and the room enters natural room temperature mode. During short periods of use, because the phase change material faces outward, less heat is required to heat the wall, the indoor air heats up quickly, and air conditioning energy consumption is reduced.

[0034] In winter, when users transition from short-term to long-term use, the room enters constant temperature mode: the phase-change material is moved indoors, the wall panels are closed, and the air conditioner is turned on, with the heating temperature set to 19-21°C. The phase-change material cools down outdoors, but it doesn't undergo a phase change to warm up indoors. Therefore, less heat is required to heat the wall, minimizing the impact on room temperature fluctuations.

[0035] In winter, before peak electricity demand, the building enters peak-shaving mode: with the phase-change material facing inward and the wall panels closed, the air conditioning setpoint is raised to 24°C before peak demand arrives. The phase-change material reaches its transition temperature and stores heat. When peak demand arrives, the air conditioning shuts off, allowing the phase-change material to release heat, maintaining the indoor temperature for a period of time. The building participates in the region's overall demand response program, reducing pressure on the grid.

[0036] In winter, when outdoor weather conditions are favorable, natural heating mode is used. When indoor heating is needed during winter or transitional seasons, and the outdoor temperature begins to rise above 25°C, the heating air conditioner shuts off, the phase-change material faces outward, the spotlights are activated, and the wall panels remain open. The phase-change material continues to absorb heat, raising the indoor temperature through convection through the wall gaps and heating other thermal storage elements such as the interior walls and furniture. When the outdoor temperature drops below 25°C, the phase-change material moves indoors, the walls close, and the phase-change material releases heat, slowly cooling the indoor temperature. When the room temperature drops to 20°C, the air conditioner turns on. By utilizing favorable outdoor weather conditions and the heat stored in the indoor thermal storage elements, air conditioning energy consumption is reduced.

[0037] During winter, when outdoor weather conditions are unfavorable at night, the off-peak heat storage mode is used: With the phase change material facing inward and the wall panels sealed, the air conditioner's set temperature is raised to 28°C, utilizing off-peak electricity. The phase change material reaches its transition temperature and stores heat, which is then transferred to other thermal storage elements such as interior walls and furniture. When the off-peak period ends, the air conditioner shuts off, returning to a natural room temperature. The off-peak period generally occurs before dawn in many cities, and utilizing this off-peak heat storage period can save electricity costs during morning use. This mode is suitable for buildings that are unoccupied at night.

[0038] In summer, when a room is unoccupied and then turned on, the system switches to rapid cooling mode: the phase change material faces outward, and the air conditioner's cooling temperature is set to 20-21°C. In cooling mode, the indoor air is rapidly cooled. Once the temperature reaches a comfortable level, the air conditioner's cooling temperature can be gradually adjusted to 26-27°C. If a person leaves the room for a short period of time, the phase change material rotates back inside, the air conditioner shuts off, and the room enters natural room temperature mode. During short periods of use, because the phase change material faces outward, less cooling is required to cool the walls, cooling the indoor air quickly and reducing air conditioning energy consumption.

[0039] In summer, when users transition from short-term to extended use, the system enters constant temperature mode: the phase-change material moves indoors, the wall panels close, the air conditioner turns on, and the cooling temperature is set to 26-27°C. The phase-change material warms the outdoor temperature but doesn't undergo a phase change when cooling indoors. Therefore, the cooling wall requires less cooling capacity and has less impact on room temperature fluctuations.

[0040] In summer, before peak electricity demand, the building enters peak-shaving mode: the phase-change material faces inward and the wall panels are closed. Before peak demand, the air conditioning setpoint is lowered to 22°C, allowing the phase-change material to reach its transition temperature and store cold. When peak demand arrives, the air conditioning shuts off, allowing the phase-change material to release the cold, maintaining the indoor temperature for a period of time. The building participates in the region's overall demand response program, reducing pressure on the power grid.

[0041] In summer, when outdoor weather conditions are favorable, natural cooling mode is used: In summer, when the outdoor temperature begins to drop below 22°C, the cooling air conditioner shuts off, the phase change material faces outward, and anti-light tracking is activated (selecting an angle that minimizes direct sunlight or diffuse sky reflection, both daytime and nighttime). The phase change material continuously absorbs cold air, lowering the indoor temperature through convection through the wall gaps. This also cools other heat storage elements, such as interior walls and furniture. When the outdoor temperature rises above 22°C, the phase change flips indoors, the walls close, the phase change material releases cold air, and the indoor temperature slowly rises. When the room temperature reaches 26°C, the air conditioner turns on. By utilizing favorable outdoor weather conditions and the cold storage of indoor heat storage elements, air conditioning energy consumption is reduced.

[0042] During summer nights when outdoor weather conditions are unfavorable, off-peak power storage mode is used: With the phase change material facing inward and the wall panels sealed, the air conditioner's set temperature is lowered to 18°C, utilizing off-peak power. The phase change material reaches its transition temperature and stores cold, while other thermal storage elements, such as interior walls and furniture, also store the cold. When the off-peak power period ends, the air conditioner shuts off, returning to a natural room temperature. The off-peak power period, typically before dawn in various cities, occurs during this time. Using this off-peak power period to store cold can save electricity costs during morning use. This mode is suitable for buildings that are unoccupied at night.

[0043] Example 2

[0044] Lightweight enclosure panels are made of high-temperature and low-temperature phase change materials arranged alternately. The phase change temperatures are: the low-temperature phase change material is at 18-19°C, and the high-temperature phase change material is at 27-28°C.

[0045] Air conditioning heating temperatures are generally set at 20-21°C in winter, and 25-26°C in summer. Personnel are encouraged to dress warmly in winter and use slow-speed fans in summer to achieve energy savings and carbon reduction while maintaining comfort levels while reducing heating and cooling loads.

[0046] When the room is unoccupied, the room is in natural room temperature mode: the phase change material faces inward, the wall panels are closed, and the air conditioner is off. This utilizes the wall panels' excellent insulation, sealing, and heat storage properties to reduce indoor temperature fluctuations. The air conditioner is not on, so no energy is consumed.

[0047] In winter, when a room is switched from unoccupied to occupied, the system switches to rapid heating mode: the phase change material faces outward, and the air conditioner's heating temperature is set to 25-26°C. In this heating mode, the indoor air is rapidly heated. Once the temperature reaches a comfortable level, the heating temperature can be gradually adjusted to 19-21°C. If a person leaves the room for a short period of time, the phase change material rotates back inside, the air conditioner shuts off, and the room enters natural room temperature mode. During short periods of use, because the phase change material faces outward, less heat is required to heat the wall, the indoor air heats up quickly, and air conditioning energy consumption is reduced.

[0048] In winter, when the building transitions from short-term to extended use, it enters constant temperature mode: the phase change material is moved indoors, the wall panels are closed, and the air conditioner is turned on, with the heating temperature set to 20-21°C. The phase change material heats the room, while the low-temperature phase change material stores heat through phase change. During building operation, the indoor temperature remains constant. It is expected that before the building enters a period of no use or low usage, the air conditioner will be turned off, allowing the phase change material to release heat to maintain a gradual cooling of the indoor temperature. This reduces air conditioning use, achieving energy savings and carbon reduction.

[0049] In winter, before peak electricity demand, the building enters peak-shaving mode: the phase-change material faces inward, the wall panels are closed, and the air conditioner is on, set to a heating temperature of 20-21°C. Once the low-temperature phase-change material reaches its transition temperature, it stores heat. When peak demand arrives, the air conditioner shuts off, allowing the phase-change material to release heat, maintaining the indoor temperature for a period of time. The building participates in the region's overall demand response program, reducing pressure on the grid.

[0050] In winter, when outdoor weather conditions are favorable, the system operates in natural heating mode. When indoor heating is needed during winter or transitional seasons, and the outdoor temperature rises above 21°C, the heating air conditioner shuts off, the phase change material faces outward, and the tracking light is activated. The phase change material continuously absorbs heat. The low-temperature phase change material undergoes a phase change due to the outdoor temperature, while the high-temperature phase change material, heated by the tracking light, reaches a phase change condition and stores heat. Air convection through the wall gaps raises the indoor temperature and heats other heat storage elements, such as the interior walls and furniture. When the outdoor temperature drops below 18°C, the phase change material moves indoors, the walls close, and the phase change material releases heat, slowly cooling the indoor temperature. When the room temperature drops to 18°C, the air conditioner turns on. By utilizing favorable outdoor weather conditions and indoor heat storage, air conditioning energy consumption is reduced.

[0051] During winter, when outdoor weather conditions are unfavorable at night, the off-peak power heat storage mode is used: With the phase change material facing inward and the wall panels sealed, the air conditioner's set temperature is raised to 28°C using off-peak power. The low- and high-temperature phase change materials reach their phase transition temperature and store heat, while other heat storage elements, such as interior walls and furniture, also store heat. When the off-peak power period ends, the air conditioner shuts off, returning to a natural room temperature. The off-peak power period, typically before dawn in various cities, occurs. Using this off-peak power period to store heat can save electricity costs during morning use. This mode is suitable for buildings that are unoccupied at night.

[0052] In summer, when a room is unoccupied and then turned on, the system switches to rapid cooling mode: the phase change material faces outward, and the air conditioner's cooling temperature is set to 20-21°C. In cooling mode, the indoor air is rapidly cooled. Once the temperature reaches a comfortable level, the air conditioner's cooling temperature can be gradually adjusted to 25-26°C. If a person leaves the room for a short period of time, the phase change material rotates back inside, the air conditioner shuts off, and the room enters natural room temperature mode. During short periods of use, because the phase change material faces outward, the wall's cooling capacity is reduced, the indoor air cools quickly, and air conditioning energy consumption is reduced.

[0053] In summer, when the building transitions from short-term to extended use, it enters constant temperature mode: the phase change material is moved indoors, the wall panels are closed, and the air conditioner is turned on, with the cooling temperature set to 25-26°C. The phase change material cools the room, and the high-temperature phase change material accumulates cold energy through phase change. During building operation, the indoor temperature is maintained constant. It is expected that before entering a period of no use or low usage, the air conditioner will be turned off, allowing the phase change material to release cold energy to maintain a slow indoor temperature increase. This reduces air conditioning use and achieves energy conservation and carbon reduction.

[0054] In summer, before peak electricity demand, the building enters peak-shaving mode: the phase-change material faces inward, the wall panels are closed, and the air conditioner is on, set to a cooling temperature of 25-26°C. The high-temperature phase-change material stores cold below the transition temperature. When peak demand arrives, the air conditioner shuts off, releasing the cold energy from the phase-change material, slowly raising the indoor temperature over time. The building participates in the region's overall demand response program, reducing pressure on the power grid.

[0055] In summer, when outdoor weather conditions are favorable, natural cooling mode is used. During summer or transitional seasons, when indoor cooling is needed and the outdoor temperature begins to drop below 25°C, the cooling air conditioner shuts off, the phase change mechanism faces outward, and anti-sun tracking is activated (to avoid direct sunlight; this is not necessary at night). The phase change material continuously absorbs cold air, lowering the indoor temperature through convection through the wall gaps. This also cools other heat storage elements, such as interior walls and furniture. When the outdoor temperature rises above 26°C, the phase change mechanism flips indoors, the walls close, the phase change material releases cold air, and the indoor temperature rises slowly. By utilizing favorable outdoor weather conditions and indoor heat storage, air conditioning energy consumption is reduced.

[0056] During summer nights when outdoor weather conditions are unfavorable, the off-peak power cooling mode is used: With the phase change materials facing inward and the wall panels sealed, the air conditioner's set temperature is lowered to 18°C, utilizing off-peak power. Both the high- and low-temperature phase change materials reach their phase change temperatures, storing cold. Other thermal storage elements, such as interior walls and furniture, also store cold. When the off-peak power period ends, the air conditioner shuts off, returning to a natural room temperature. The off-peak power period, typically before dawn in various cities, occurs during this time. Using this off-peak power period to store cold can save energy and reduce carbon emissions during morning use. This mode is suitable for buildings that are unoccupied at night.

[0057] Examples 1 and 2 above, with intermittent air conditioning, offer natural room temperature mode when unused, rapid cooling and heating mode when active, constant temperature mode for extended periods, and natural cooling and heating mode when outdoor weather conditions are favorable. These modes achieve direct energy conservation and carbon reduction. Peak shaving mode during peak hours and thermal and cooling storage during off-peak hours alleviate power demand on the grid, facilitating energy utilization and overall grid stability, while also saving electricity costs to a certain extent.

[0058] Example 3

[0059] In the natural heating or natural cooling mode of the above-mentioned embodiment 1 or embodiment 2, the opening angle, the size of the gap, and the number of open light enclosure panels can be further controlled to achieve the conversion functions of wind guidance and sealing, dimming and shading, and soundscape and sound insulation. These conversion functions can be intelligently controlled automatically or controlled by the user. On the basis of combining climate conditions and room functions to achieve energy conservation and carbon reduction, it can meet the personalized control of wind, light, sound and other aspects.
