Description

Technical Field

[0001] This invention relates to the field of building energy conservation, and in particular to a composite insulation board for zero-energy buildings and its application method. Background Technology

[0002] With the national carbon neutrality goal being set, the requirements for energy conservation and emission reduction in both new and existing buildings are becoming increasingly stringent. Currently, building insulation materials are widely used in low-energy buildings, primarily by installing different static insulation materials on the exterior, interior, or middle surfaces of the building walls. For buildings using static insulation materials, achieving continuous reduction in building energy consumption requires continuously increasing the thickness of the insulation layer to lower the overall heat transfer coefficient of the building envelope. However, the extensive use of static insulation materials in buildings presents several problems. First, excessively thick insulation layers occupy a significant amount of valuable usable space within the building. Second, the fire hazard associated with static insulation materials remains unresolved, and their widespread use increases the risk of fire. Third, static insulation materials themselves are industrial products with high hidden carbon emissions, and their extensive use contradicts the carbon neutrality goals in the building sector. Furthermore, the thermal resistance of static insulation layers cannot be changed during use, which is detrimental to the use of cooling energy during transitional seasons and nighttime cooling periods; excessive use of insulation layers may actually lead to an increase in building energy consumption. Against this backdrop, if static insulation materials are used on a larger scale in zero-energy buildings with even higher energy efficiency requirements, the aforementioned problems will undoubtedly become more prominent. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a composite insulation board and its application method suitable for energy-saving renovation of various new buildings and existing buildings. This board can effectively reduce the amount of traditional building insulation materials used in zero-energy buildings, while also effectively improving energy-saving and consumption-reducing effects.

[0004] The technical solution adopted to achieve the purpose of this invention is:

[0005] A composite insulation board for zero-energy buildings includes an outer insulation board, a first substrate, a second substrate, a flat heat pipe array, a heat source, and a flat heat pipe array tilt adjustment system. The second substrate is fixed on the outer insulation board. The flat heat pipe array tilt adjustment system is used to control the rotation angle of the parallel heat pipe array and is installed between the first substrate and the second substrate. The heat source is installed on the first substrate or the second substrate. The outer insulation board is fixed to the outside of the first substrate.

[0006] Preferably, the flat plate heat pipe array tilt adjustment system is mounted on the first substrate and consists of a drive motor, a drive rod, a drive rod guide rail, a drive rod pin shaft, and a heat pipe rotation shaft. The motor and the drive rod guide rail are mounted on the first substrate. One end of the drive rod is connected to the drive motor, and the rod body is placed in the drive rod guide rails arranged on the left and right. The flat plate heat pipe array is mounted on the first substrate through the heat pipe rotation shaft located in the middle position. The top of the flat plate heat pipe array cooperates with the drive rod pin shaft through an adjustment groove, and the bottom of the flat plate heat pipe array is in contact with the heat source mounted on the first substrate.

[0007] Preferably, the flat plate heat pipe array tilt adjustment system is mounted on the second base plate and consists of a drive motor, a drive rod, a drive rod guide rail, a drive rod pin shaft, and a heat pipe rotation shaft. The motor and the drive rod guide rail are mounted on the second base plate. One end of the drive rod is connected to the drive motor, and the rod body is placed in the drive rod guide rails arranged on the left and right. The flat plate heat pipe array is mounted on the second base plate through the heat pipe rotation shaft located in the middle position. The top of the flat plate heat pipe array cooperates with the drive rod pin shaft through an adjustment groove, and the bottom of the flat plate heat pipe array is in contact with the heat source mounted on the second base plate.

[0008] A method for using a zero-energy building composite insulation board, with three usage modes:

[0009] Thermal insulation mode: When the temperature of the low-grade renewable energy available in the zero-energy building is between 16-25℃, the control system will send the corresponding tilt angle adjustment command of the thermal insulation mode to the flat plate heat pipe array tilt angle adjustment system. Then the tilt angle adjustment system will control the α value of the flat plate heat pipe array within 15-45°. Subsequently, the low-grade renewable energy with a temperature range of 16-25℃ from the heat source will be evenly injected into the composite insulation board through the flat plate heat pipe array. Then, it will diffuse evenly towards the wall through the second substrate in contact with the wall, and finally form a thermal barrier with a temperature between 16-25℃ between the second substrate and the wall.

[0010] Auxiliary energy supply mode: When the temperature of the low-grade renewable energy available in the zero-energy building is between 26-35℃, the control system will send the tilt angle adjustment command corresponding to the auxiliary energy supply mode to the flat plate heat pipe array tilt angle adjustment system. Subsequently, the tilt angle adjustment system will control the α value corresponding to the flat plate heat pipe array within 46-75°. Then, the low-grade renewable energy with a temperature range of 26-35℃ from the heat source will be evenly injected into the composite insulation board through the flat plate heat pipe array. Then, it will diffuse evenly towards the wall through the second substrate in contact with the wall, and finally form a thermal barrier with a temperature between 26-35℃ between the second substrate and the wall.

[0011] Direct Energy Supply Mode: When the temperature of the low-grade renewable energy available in the zero-energy building is above 36°C, the control system sends a tilt angle adjustment command corresponding to the direct energy supply mode to the flat plate heat pipe array tilt angle adjustment system. Subsequently, the tilt angle adjustment system will control the α value corresponding to the flat plate heat pipe array within 76-90°. Then, the low-grade renewable energy with a temperature greater than 36°C from the heat source will be evenly injected into the composite insulation board through the flat plate heat pipe array. Then, it will diffuse evenly towards the wall through the second substrate in contact with the wall, and finally form a thermal barrier with a temperature higher than 36°C between the second substrate and the wall.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: the zero-energy building composite insulation board of this invention is less affected by the building construction stage and has a simple installation process. It is suitable for both new buildings and energy-saving renovations of existing buildings, and has great potential for application and promotion; the zero-energy building composite insulation board of this invention has no cycle-driven energy consumption during the injection of low-grade renewable energy; under different building environment control requirements and corresponding usage modes, the composite insulation board can achieve the best low-grade renewable energy heat injection efficiency through precise control of the tilt angle by the flat plate heat pipe array tilt angle adjustment system; under the same wall thermal performance conditions, because it has both traditional insulation layer and flat plate heat pipe heat injection layer composite insulation and heat insulation methods, the thickness of the zero-energy building composite insulation board of this invention can be significantly reduced compared to insulation boards. The amount of traditional insulation materials with high hidden carbon emissions used in the components, the building space occupation, and the transportation space occupation are also less. Furthermore, it can significantly reduce or even completely eliminate the installation capacity and initial investment and operating costs of high-performance indoor air conditioning systems.

[0014] Figure 2 The diagram shown is an AA-axis view of the zero-energy building composite insulation board of the present invention. Detailed Implementation

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0016] The present invention provides a zero-energy building composite insulation board, such as Figures 1-2As shown, it is integrated on the outside of the base wall 1 and includes an external insulation board 2, a first base plate 3 and a second base plate 4, a flat heat pipe array 5, a heat source 6, and a flat heat pipe array tilt adjustment system 7. The flat heat pipe array tilt adjustment system 7 is mounted on the first base plate 3 and consists of a drive motor 71, a drive rod 72, a drive rod guide rail 73, a drive rod pin shaft 74, and a heat pipe rotation shaft 75. The motor 71 and the drive rod guide rail 73 are mounted on the first base plate 3. One end of the drive rod 72 is connected to the drive motor 71, and the rod body is placed in the drive rod guide rails 73 arranged on the left and right. The flat heat pipe array 5 is mounted on the first base plate 3 through the heat pipe rotation shaft 75 located in the middle. Its top is engaged with the drive rod pin shaft 74 through an adjustment groove 51, and its bottom is in contact with the heat source 6 mounted on the first base plate 3. The heat from the heat source 6 is transferred upwards to the second base plate through the flat heat pipe array 5, and then further transferred to the base wall 1 adjacent to the second base plate. The flat plate heat pipe array tilt adjustment system 7 can also be installed on the second base plate 4. The corresponding motor 71, drive rod rail 73 and heat pipe rotation shaft 75 are installed on the second base plate. Other components are installed in the same way as described above. However, considering that more heat can be directly transferred to the foundation wall, it is preferable to install the tilt adjustment system on the first base plate.

[0017] Depending on the grade of low-grade renewable energy available for the building and the different requirements for indoor environmental control, the composite insulation board for zero-energy buildings of the present invention has the following three tilt angle control and usage methods: thermal insulation mode, auxiliary energy supply mode, and direct energy supply mode.

[0018] Since the heat source is transferred through a flat plate heat pipe array, and the thermal conductivity of the flat plate heat pipe array is directly related to both the heat source temperature and the tilt angle, the tilt angle of the flat plate heat pipe array must be actively adjusted under different operating modes to ensure the composite insulation board achieves optimal thermal insulation performance in actual operation. Therefore, the tilt angle of the flat plate heat pipe array is a key parameter and a key parameter protected in this patent. The relationship between the tilt angle of the flat plate heat pipe array and the heat source temperature shown in Table 1 can achieve the optimal heat transfer effect; the data comes from previous experimental tests.

[0019] Table 1 Heat Source Temperature, Tilt Angle Adjustment and Usage Method

[0020] Heat source temperature Inclination angle α How to use 16-25℃ 15-45° Thermal insulation 26-35℃ 46-75° Auxiliary power supply ≥36℃ 76-90° direct energy supply

[0021] Thermal Insulation Mode: When the temperature of the low-grade renewable energy available in the zero-energy building is between 16-25℃, the control system will send a tilt angle adjustment command corresponding to the thermal insulation mode to the flat plate heat pipe array tilt angle adjustment system. The tilt angle adjustment system will then control the corresponding α value of the flat plate heat pipe array within 15-45° (α is the angle between the axis of a single flat plate heat pipe in the flat plate heat pipe array 5 and the X-axis, with the heat pipe rotation axis 75 as the center). Subsequently, the low-grade renewable energy from the heat source 6, with a temperature range of 16-25℃, will be evenly injected into the composite insulation board through the flat plate heat pipe array. It will then diffuse evenly towards the wall via the second substrate 4 in contact with the wall, ultimately forming a thermal barrier with a temperature between 16-25℃ between the second substrate 4 and the wall. Under the active thermal insulation effect of this thermal barrier, the heat loss from the building interior to the exterior through the building envelope can be significantly reduced, thus achieving thermal insulation.

[0022] Auxiliary Energy Supply Mode: When the temperature of the low-grade renewable energy available in the zero-energy building is between 26-35°C, the control system will send an auxiliary energy supply mode tilt angle adjustment command to the flat plate heat pipe array tilt angle adjustment system. The tilt angle adjustment system will then control the corresponding α value of the flat plate heat pipe array within the range of 46-75°. Subsequently, the low-grade renewable energy from heat source 6, with a temperature range of 26-35°C, will be evenly injected into the composite insulation board through the flat plate heat pipe array. It will then diffuse evenly towards the wall via the second substrate 4 in contact with the wall, ultimately forming a thermal barrier with a temperature between 26-35°C between the second substrate 4 and the wall. Because the temperature of the thermal barrier is higher than the building's winter indoor set temperature, the thermal barrier not only reduces heat loss through the building envelope to zero but also provides auxiliary energy to the indoor space.

[0023] Direct Energy Supply Mode: When the temperature of the low-grade renewable energy available in the zero-energy building is above 36°C, the control system sends a tilt angle adjustment command corresponding to the direct energy supply mode to the flat plate heat pipe array tilt angle adjustment system. The tilt angle adjustment system then controls the corresponding α value of the flat plate heat pipe array within the range of 76-90°. Subsequently, the low-grade renewable energy with a temperature greater than 36°C from heat source 6 is evenly injected into the composite insulation board through the flat plate heat pipe array. It then diffuses evenly towards the wall via the second substrate 4 in contact with the wall, ultimately forming a thermal barrier with a temperature higher than 36°C between the second substrate 4 and the wall. Because the temperature of the thermal barrier is significantly higher than the set indoor temperature in winter, this thermal barrier directly provides the required heat to the indoor space.

[0024] The above description is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
