Description

Technical Field

[0001] The present invention relates to the technical field of building exterior wall thermal insulation, in particular to an assembled breathing building exterior wall with adjustable heat transfer capacity. Background Art

[0002] The building's exterior wall is the outermost part of the building and has a significant impact on the energy consumption of ultra-low energy buildings. Currently, ultra-low energy buildings often use brickwork, self-insulating blocks, or wall panels for their exterior walls. However, these three construction methods, combined with building insulation measures, result in significant thermal inertia.

[0003] In reality, the relative temperature between indoor and outdoor temperatures in ultra-low-energy buildings fluctuates throughout the year. For example, in northern China, summers are typically hot outside, and indoor air conditioning is used to cool the interior. In these situations, walls with strong thermal inertia are indeed necessary to prevent outdoor heat from entering through the walls. Conversely, in northern China, winters are typically cold outside, and indoor heating is used to raise the temperature. In these situations, walls with strong thermal inertia are also necessary to prevent indoor heat from escaping through the walls. However, in southern cities, winters are typically cold inside and warm outside. In these situations, thermally inert walls prevent outdoor heat from entering the interior.

[0004] Therefore, a single strong thermal inert exterior wall can no longer meet the demand for ultra-low energy consumption buildings to reduce energy consumption, and there are few building exterior walls with adjustable heat transfer capabilities, which cannot meet the immediate needs of ultra-low energy consumption buildings. Summary of the Invention

[0005] In view of the problem that the building exterior walls in the prior art cannot simultaneously reduce energy consumption and adjust heat transfer capacity, the present invention provides an assembled breathing building exterior wall with adjustable heat transfer capacity.

[0006] The present invention is achieved through the following technical solutions:

[0007] A prefabricated breathing building exterior wall with adjustable heat transfer capacity comprises: HVAC equipment, indoor end wall panels, outdoor end wall panels, sandwich panels, outdoor end heat accumulators, indoor end heat accumulators and a connection control device, wherein the indoor end wall panels, sandwich panels and outdoor end wall panels are sequentially arranged between the upper floor and the lower floor, a first cavity is formed between the indoor end wall panels and the sandwich panels, and a second cavity is formed between the outdoor end wall panels and the sandwich panels, the first cavity is connected to the indoor room, and the second cavity is connected to the outdoor room; the connection control device is arranged on the sandwich panels, for controlling the connection between the first cavity and the second cavity; the outdoor end heat accumulator and the indoor end heat accumulator are respectively located in the first cavity and the second cavity, and are both connected to the sandwich panels; the HVAC equipment is connected to the second cavity, and at least two HVAC equipment are provided, which are respectively arranged on the upper and lower sides of the second cavity, and an electric insulation regulating valve is provided at the connection between the second cavity and the outdoor room.

[0008] Preferably, the connection control device includes a driving machine, a first partition plate and a second partition plate, the first partition plate and the second partition plate are arranged in a cross shape, and a rotating part is provided at the intersection of the first partition plate and the second partition plate, the output end of the driving machine is connected to the rotating part, and a through groove is provided on the first partition plate; when the first cavity and the second cavity are connected, the first partition plate is not perpendicular to the sandwich plate.

[0009] Preferably, a through hole is opened on the outdoor end wall panel, and rainproof louvers are arranged on the inner side of the through hole.

[0010] Preferably, an electrostatic dust removal net is further provided at the through hole, the electrostatic dust removal net is connected to the power supply equipment through the circuit, and the electrostatic dust removal net is located on the inner side of the rainproof louver.

[0011] Preferably, both the indoor end heat accumulator and the outdoor end heat accumulator are profile radiators, presenting a multi-layer continuous sheet structure.

[0012] Preferably, in a gas flow environment, the temperature of the indoor end heat accumulator is the same as the indoor temperature, and the temperature of the outdoor end heat accumulator is the same as the outdoor temperature.

[0013] Preferably, when the outdoor temperature is high and the indoor temperature is cooled by air-conditioning equipment, the connection control device is adjusted to connect the first cavity with the second cavity, the HVAC equipment is in the open state, and the electric insulation regulating valve is opened at the same time, and the outdoor heat and indoor heat are both sucked into the second cavity. At the same time, the outdoor end heat accumulator and the indoor end heat accumulator are both storing heat; when the HVAC equipment is turned off, the temperature of the indoor end heat accumulator is lower than the temperature of the outdoor end heat accumulator.

[0014] Preferably, when the outdoor temperature is high and the indoor temperature is raised by the heating equipment, the connection control device is adjusted to isolate the first cavity from the second cavity, the HVAC equipment and the electric insulation regulating valve are turned on, and the outdoor heat enters the second cavity and is stored in the outdoor heat accumulator; when the temperature of the outdoor heat accumulator is higher than the temperature of the indoor heat accumulator, the electric insulation regulating valve and the HVAC equipment are closed; then the first cavity and the second cavity are connected, and the heat of the outdoor heat accumulator is transferred to the room through the first cavity, and the indoor temperature rises.

[0015] Preferably, when the outdoor temperature is low and the indoor temperature is raised by heating equipment, the connection control device is adjusted to separate the first cavity from the second cavity, the electric insulation regulating valve is closed, and the closed second cavity is used to separate the indoor environment from the outdoor environment.

[0016] Preferably, when the indoor temperature is higher than the outdoor temperature, the connection control device is adjusted to connect the first cavity with the second cavity, and the electric insulation regulating valve is opened at the same time, so that the indoor heat is discharged outdoors through the first cavity and the second cavity.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention provides an assembled breathing building with adjustable heat transfer capacity. The outer wall is provided with a connection control device to achieve the connection or isolation between the first cavity and the second cavity, so that different heat or air circulation cycles are formed outdoors, indoors, in the first cavity, and in the second cavity. Combined with the heat storage function of the outdoor end heat accumulator and the indoor end heat accumulator, the heat is further adjusted, the indoor temperature is maintained, and energy consumption is reduced.

[0019] Furthermore, the driving motor drives the first partition plate and the second partition plate to move and change positions. When the first partition plate and the sandwich plate are not perpendicular, the first cavity is connected to the second cavity. When the first partition plate and the sandwich plate are perpendicular, the first cavity is separated from the second cavity.

[0020] Furthermore, the rainproof louvers can shield the through holes to prevent rainwater or other debris from entering the second cavity through the through holes and causing blockage.

[0021] Furthermore, an electrostatic dust removal net is used to filter dust.

[0022] Furthermore, when outdoor temperatures are high and indoor air conditioning is used for cooling, as in the summer in northern and southern China, the first and second chambers are connected, and the HVAC system is turned on, causing air in the second chamber to flow upward from the bottom. According to Bernoulli's principle, both indoor and outdoor air are drawn into the second chamber, forming a bottom-up flow before being exhausted by the HVAC system above. This process removes the warmer air from the room, thereby reducing the cooling load of the air conditioning and lowering energy consumption to maintain the indoor temperature.

[0023] Furthermore, when the outdoor temperature is high, the indoor temperature is raised by heating equipment. In the winter in the southern region, the first cavity is isolated from the second cavity, and the electric thermal insulation regulating valve and HVAC equipment are opened, so that the hotter air outside is sucked into the second cavity, and the temperature of the outdoor heat accumulator is close to the temperature of the outdoor environment. Then the electric thermal insulation regulating valve and HVAC equipment are closed, and then the first cavity and the second cavity are connected, so that the first cavity and the second cavity are connected. At this time, the ambient temperature in the first cavity is lower, and the temperature of the indoor heat accumulator must be lower than the temperature of the outdoor heat accumulator. Therefore, the second cavity and the outdoor heat accumulator will conduct to the first cavity and the indoor heat accumulator. Since the first cavity is connected with the indoor environment, the indoor temperature will rise, that is, the indoor heat load will be reduced.

[0024] Furthermore, when it is cold outside and the temperature inside is high due to heating equipment, during normal use, such as winter in northern regions, the first cavity is separated from the second cavity, and the electric insulation regulating valve is closed. At this time, the second cavity is in a closed state, that is, the second cavity will separate the indoor and outdoor environments in a closed form, which will make the exterior wall of the building have stronger thermal insulation performance.

[0025] Furthermore, when the indoor temperature is higher than the outdoor temperature, such as the exterior wall of a building in a thermal power or heat power generation project, the electric regulating valve is opened, and the first cavity is connected to the second cavity. Since the outdoor air flows through the rainproof louver at a faster speed, according to the Bernoulli principle, the indoor hot air will pass through the first cavity, the second cavity, and the rainproof louver, and finally reach the outdoors, reducing the indoor cooling load.

[0035] The present invention will be further described in detail below with reference to specific embodiments, which are intended to explain the present invention rather than to limit it.

[0036] The present invention discloses an assembled breathing building exterior wall with adjustable heat transfer capacity, referring to Figure 1 , including HVAC equipment 100, indoor end wall panel 1, outdoor end wall panel 2, sandwich panel 3, outdoor end heat accumulator 4, indoor end heat accumulator 5 and communication control device. The indoor end wall panel 1, sandwich panel 3 and outdoor end wall panel 2 are sequentially arranged between the upper floor 200 and the lower floor 300. A first cavity is formed between the indoor end wall panel 1 and the sandwich panel 3, and a second cavity is formed between the outdoor end wall panel 2 and the sandwich panel 3. The first cavity is connected to the indoor, and the second cavity is connected to the outdoor. In this embodiment, the indoor end wall panel 1, the outdoor end wall panel 2 and the sandwich panel 3 are all made of autoclaved aerated concrete, which has strong thermal inertia. At least two HVAC equipment 100 are provided, divided into two groups and respectively arranged on the upper and lower sides of the second cavity. A ventilation hole is opened on the indoor end wall panel 1, and an air inlet louver 10 is installed on the ventilation hole. In this embodiment, the HVAC equipment 100 can be respectively arranged on the upper floor 200 and the lower floor 300.

[0037] Reference Figure 2 A through hole is opened on the outdoor end wall panel 2, and a rainproof shutter 21 is set on the inner side of the through hole.

[0038] Reference Figure 3 An electrostatic dust removal net 22 is also provided at the through hole. The electrostatic dust removal net 22 is connected to the power supply equipment through a circuit. The electrostatic dust removal net 22 is located on the inner side of the rainproof louver 21. When the HVAC equipment 100 is turned on, the airflow flows from bottom to top, and the outdoor air will enter from the through hole. The electrostatic dust removal net 22 is opened to prevent dust from entering when the outdoor air enters the second cavity. The electrostatic dust removal net 22 has low resistance and will not produce obvious resistance to the outdoor air.

[0039] Reference Figure 1 、 4 5. The connection control device is provided on the sandwich plate 3 and is used to control the connection between the first cavity and the second cavity; the connection control device includes a driving motor, a first partition plate 6 and a second partition plate, the first partition plate 6 and the second partition plate are arranged in a cross shape, and a rotating member 9 is provided at the intersection of the first partition plate 6 and the second partition plate, the output end of the driving motor is connected to the rotating member 9, and a through slot 8 is provided on the first partition plate 6; when the first cavity and the second cavity are connected, the first partition plate 6 is not perpendicular to the sandwich plate 3. In this embodiment, the driving motor is a motor, the output shaft of the motor is connected to the rotating member 9, and the first partition plate 6 and the second partition plate are driven to rotate by the rotation of the motor, and the motor drives the first partition plate 6 to switch between two states. In the first state, when the first partition plate 6 is parallel to the sandwich plate 3, the first cavity and the second cavity are connected through the through slot 8; the motor drives the first partition plate 6 to rotate 90°, which is the second state. At this time, the second partition plate is parallel to the sandwich plate 3, and the first cavity is separated from the second cavity.

[0040] Reference Figure 1The outdoor heat accumulator 4 and the indoor heat accumulator 5 are located in the first and second cavities, respectively, and are both connected to the sandwich panel 3. In a flowing gas environment, the temperature of the indoor heat accumulator 5 is the same as the indoor temperature, and the temperature of the outdoor heat accumulator 4 is the same as the outdoor temperature. Both the indoor heat accumulator 5 and the outdoor heat accumulator 4 are profiled radiators. In this embodiment, the indoor heat accumulator 5 is made of aluminum or copper and has a multi-layer continuous sheet structure. The multi-layer sheet structure is connected by a columnar structure made of the same material. This ensures that the indoor heat accumulator 5 maintains the same temperature as the surrounding environment in either hot or cold flowing environments.

[0041] The HVAC equipment 100 is connected to the second cavity; an electric thermal insulation regulating valve 23 is provided at the connection point between the second cavity and the outside, and the electric thermal insulation regulating valve 23 is embedded in the outdoor end wall panel 2.

[0042] Reference Figure 6 In the summer in northern and southern China, when the outdoor temperature is high and the indoor temperature is cooled by air conditioning, the connection control device connects the first and second cavities, turning HVAC equipment 100 on. Simultaneously, the electric heat-insulating control valve 23 is opened, drawing both outdoor and indoor heat into the second cavity. Both outdoor heat accumulator 4 and indoor heat accumulator 5 store heat. When HVAC equipment 100 is off, the temperature of indoor heat accumulator 5 is lower than that of outdoor heat accumulator 4.

[0043] During this process, the air in the first and second cavities is connected, and the HVAC equipment 100 is turned on, allowing the air in the second cavity to flow from bottom to top. According to Bernoulli's principle, the indoor air and outdoor air are drawn into the second cavity, forming a bottom-up flow direction, and are finally discharged by the HVAC equipment 100 above. This process removes the warmer air in the room, thereby reducing the indoor air conditioning cooling load and energy consumption to maintain the indoor temperature. In the above process, although the air entering through the rainproof louvers 21 is hot, it reduces the air intake load of the HVAC equipment 100. Since the heat entering the second cavity is ultimately discharged, the hot air entering through the rainproof louvers 21 actually reduces the building's cooling load.

[0044] In addition, when the HVAC equipment 100 drives air to flow from bottom to top, both the outdoor heat accumulator 4 and the indoor heat accumulator 5 will store heat. Specifically, the temperature of the outdoor heat accumulator 4 is close to the outdoor ambient temperature due to the outdoor air entering the second cavity to store heat, and the indoor heat accumulator 5 is close to the indoor ambient temperature. Therefore, the temperature of the indoor heat accumulator 5 will be lower than the temperature of the outdoor heat accumulator 4. Therefore, when the HVAC equipment 100 is completed, the connection control device should also be closed (i.e., the first cavity and the second cavity are isolated). This is to prevent the heat of the outdoor heat accumulator 4 from flowing into the first cavity through the through groove 8. At this time, the electric insulation control valve 23 should still be in the open state. The outdoor air flow rate is significantly greater than the air flow rate in the second cavity. At this time, the hotter air in the second cavity that was sucked into the second cavity earlier will be sucked out through the rainproof louver 21 according to Bernoulli's principle, lowering the air temperature in the second cavity. At the same time, the outdoor heat accumulator 4 will also cool down.

[0045] Afterwards, the user closes the electric insulation regulating valve 23 in time according to the cooling situation in the second cavity. At this time, the second cavity is in a closed state, and the temperature of the second cavity is between the indoor temperature and the outdoor temperature. The second cavity acts as an insulation structure to reduce the tendency of outdoor heat to flow into the room.

[0046] Reference Figure 7 、 8 In the winter in the southern region, when the outdoor temperature is high and the indoor temperature is raised by the heating equipment, the connection control device is adjusted to isolate the first cavity from the second cavity, and the HVAC equipment 100 and the electric insulation regulating valve 23 are opened, so that the air in the second cavity flows from bottom to top, and the outdoor heat will enter the second cavity and be stored in the outdoor end heat accumulator 4; when the temperature of the outdoor end heat accumulator 4 is higher than the temperature of the indoor end heat accumulator 5, the electric insulation regulating valve 23 and the HVAC equipment 100 are closed; then the first cavity and the second cavity are connected, and the heat of the outdoor end heat accumulator 4 is transferred to the room through the first cavity, the indoor temperature remains unchanged and the indoor heat load is reduced, or the indoor temperature is increased and the indoor heat load is reduced.

[0047] During this process, the first cavity is initially isolated from the second cavity, the electric insulation regulating valve 23 is in the open state, and the HVAC equipment 100 is also in the open state, so that the hotter air outside is sucked into the second cavity, and the temperature of the outdoor end heat accumulator 4 is close to the temperature of the outdoor environment. Then the electric insulation regulating valve 23 and the HVAC equipment 100 are closed, and then the first cavity and the second cavity are connected. At this time, the ambient temperature in the first cavity is lower, and the temperature of the indoor end heat accumulator 5 must be lower than the temperature of the outdoor end heat accumulator 4. Therefore, at this time, the second cavity and the outdoor end heat accumulator 4 will conduct to the first cavity and the indoor end heat accumulator 5. Since the first cavity is connected to the indoor environment, the indoor temperature will increase, that is, the indoor heat load will be reduced.

[0048] During normal use, such as in the winter in northern regions, when the outdoor temperature is low and the indoor temperature is raised by heating equipment, the connection control device is adjusted to separate the first cavity from the second cavity, and the electric insulation regulating valve 23 is closed. The sealed second cavity is used to separate the indoor environment from the outdoor environment, thereby making the building exterior wall have stronger thermal insulation performance.

[0049] When applied to the exterior wall of a building for a thermal power or heat power generation project, when the indoor temperature is higher than the outdoor temperature, the connection control device is adjusted to connect the first cavity with the second cavity, and the electric insulation regulating valve 23 is opened at the same time. Since the outdoor air flows through the rainproof louver 21 at a faster speed, according to the Bernoulli principle, the indoor heat is discharged to the outside through the first cavity and the second cavity, thereby achieving the purpose of reducing the indoor cooling load.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to impose any limitation on the technical solution of the present invention. Those skilled in the art should understand that, without departing from the spirit and principles of the present invention, the technical solution can also be subjected to several simple modifications and replacements, and these modifications and replacements are also within the scope of protection covered by the claims.
