Description

Technical Field

[0002] Green building energy storage technology requires the storage of electrical energy, but finding special space inside the building will waste the building's usable area. Currently, there is a technical demand to install battery installation equipment in the building's exterior walls (including non-load-bearing surrounding walls and load-bearing surrounding walls). Such building exterior walls allow the battery modules to be disassembled and installed in the building's exterior walls.

[0003] At present, in the process of renovating the exterior walls of buildings, the exterior walls are formed by masonry bricks combined with insulation layers and waterproof layers, and then battery components are installed on the walls. Although the wall structure meets the needs of green building energy storage, such wall structures cannot achieve ventilation of indoor and outdoor air. When the wall structure is used for indoor and outdoor air exchange, windows need to be opened on the wall structure for ventilation. However, some wall structures cannot have windows, so such walls do not have the function of ventilation and cannot assist in reducing air-conditioning energy consumption in the building.

[0030] Compared with the prior art, the present invention has the following beneficial technical effects:

[0031] The present invention provides a reconstruction structure for the exterior wall of an existing building. By arranging a ventilation part between the inner wall panel and the outer wall panel, the ventilation part controls the suction and exhaust of the first folding air box and the second folding air box through a linkage component, thereby forming a heat exchange between the indoor and outdoor environments, helping to reduce the indoor heat load (underfloor heating) or cold load (air conditioning), reducing energy loss, and greatly enhancing the functionality and practicality of the building exterior wall. At the same time, the introduction of a noise reduction component in the exterior wall structure reduces the impact of external noise on the indoor environment, providing users with a quieter and more comfortable living or working environment. The exterior wall structure of the present invention is compact, ensuring the stability and reliability of the overall structure. At the same time, the exterior wall structure is easy to install and maintain, reducing the reconstruction cost and difficulty, and having high economic efficiency and feasibility.

[0032] Further, in the exterior wall structure of the present invention, the linkage component realizes the stable connection and flexible adjustment of the first folding air box and the second folding air box through the cooperation of the M-shaped metal clip and the first clamping plate. The M-shaped metal clip is clamped on the long connecting plate, which not only ensures the stability of the structure but also facilitates installation and disassembly. The fitting of the first clamping plate with the inner wall of the M-shaped metal clip enhances the connection tightness between the air boxes, effectively preventing the air boxes from shaking or separating during use. The setting of the first connecting rod and the second connecting rod provides convenience for the connection of the driving component, enabling the driving component to accurately transmit power and control the folding and unfolding of the air boxes. The second connecting side plate vertically arranged between the noise reduction component and the long connecting plate not only provides an installation space for the driving component but also further enhances the stability of the entire structure, improving the reliability and durability of the exterior wall structure, and facilitating later maintenance and servicing, reducing the use cost.

[0033] Further, the combined use of the M-shaped metal clip and the first clamping plate in the exterior wall structure enables the first folding air box and the second folding air box to be stably compressed or unfolded, ensuring the stability and safety of the ventilation part during operation. The M-shaped metal clip provides an automatic reset function for the ventilation part through the change of its own elasticity and the cooperation with the reset spring. When the driving component stops working, the reset spring can push the M-shaped metal clip and the folding air box back to the initial position, switching the operating states of the first folding air box and the second folding air box, improving the automation degree of the ventilation part, and also reducing the energy consumption and maintenance cost.

[0034] Furthermore, the setting of the heat insulation curtain in the exterior wall structure effectively reduces the heat transfer between the noise reduction component and the battery installation plate, improving the heat insulation performance of the entire exterior wall structure. Under extreme weather conditions, such as high temperature in summer or severe cold in winter, the heat insulation curtain can significantly reduce the indoor temperature fluctuation, improve the comfort of the living or working environment, and at the same time reduce energy consumption.

[0035] Furthermore, in the present exterior wall structure, the rolling and unrolling assembly enables the heat insulation curtain to be easily deployed and retracted, with simple and quick operation. The reel, as the main support structure of the heat insulation curtain, is horizontally installed on the wall between the noise reduction component and the battery mounting plate, ensuring the stability and reliability of the heat insulation curtain. The introduction of the rolling and unrolling motor realizes the automatic control of the heat insulation curtain, and users can easily control the deployment and retraction of the heat insulation curtain through a switch or a remote control, improving the convenience of use.

[0036] Furthermore, the double-layer noise reduction thin film plate in the present exterior wall structure effectively blocks the propagation path of external noise, forms an obstacle to sound propagation through the air layer between the two thin film plates, and thus greatly reduces the penetration ability of noise.

[0055] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0056] The present invention provides a reconstruction structure for the exterior wall of an existing building, such as Figures 1 to 12 shown, this exterior wall structure is a non-load-bearing enclosure wall, and the upper and lower ends of the exterior wall structure are connected to the floor beams or floor slabs, and the two side edges are connected to the structural columns. When connecting, metal connectors such as rivets and U-shaped clips are used in cooperation with sealant to connect with the building body. This exterior wall structure includes an inner wall panel 1 and an outer wall panel 2 fixed at both ends on the structural columns. The inner wall panel 1 is close to the interior, and the outer wall panel 2 is close to the exterior. Both the inner wall panel 1 and the outer wall panel 2 are vertically installed and parallel to each other. Both the inner wall panel 1 and the outer wall panel 2 need to use precast wall panels.

[0057] As Figure 1 、 Figure 2 、 Figure 3 and Figure 9As shown, a battery mounting plate 14 is arranged between the inner wall panel 1 and the outer wall panel 2. The battery mounting plate 14 is parallel to the inner wall panel 1 and the outer wall panel 2 respectively, and the battery mounting plate 14 is close to the inner wall panel 1. An I-shaped connecting groove 17 is arranged on the end surface of the battery mounting plate 14 relative to the inner wall panel 1. A slider is slidably connected to the I-shaped connecting groove 17, and a battery module 18 is installed on the slider. The position of the battery module 18 can be adjusted by the slider, so that the staff can replace or repair the battery module 18 conveniently at a later stage.

[0058] like Figures 1 to 12 As shown, a noise reduction component is provided between the battery mounting plate 14 and the outer wall panel 2, and a ventilation part is provided in the noise reduction component, through which the air inside the inner wall panel 1 is exchanged with the air outside the outer wall panel 2, so as to realize indoor and outdoor ventilation;

[0059] like Figures 1 to 7 As shown, the ventilation part includes a long connecting plate 4 parallel to the outer wall panel 2, and a plurality of long connecting plates 4 are provided, and the plurality of long connecting plates 4 are horizontally installed in the noise reduction component, and the plurality of long connecting plates 4 are vertically aligned and arranged at equal intervals from high to low; a first connecting side plate 41 is commonly connected to the same-side end heads of the plurality of long connecting plates 4, and the first connecting side plate 41 is vertically fixed to the structural column, and a plurality of linkage components are symmetrically installed at positions near the top end face and the bottom end face of each long connecting plate 4, and the plurality of linkage components near the top end face of the long connecting plate 4 are arranged at equal intervals along the length direction of the long connecting plate 4, and the plurality of linkage components near the bottom end face of the long connecting plate 4 and the plurality of linkage components near the top end face of the long connecting plate 4 are symmetrical about the center line of the long connecting plate 4 in the length direction;

[0060] like Figures 1 to 6 As shown, each linkage assembly includes an M-shaped metal clip 3, which is a metal product with sufficient strength and elasticity. A long enlarging head 36 is provided at the clamping position of the M-shaped metal clip 3, and U-shaped grooves 34 are symmetrically provided on the left and right sides of the long connecting plate 4. The U-shaped grooves 34 are provided along the length direction of the long connecting plate 4. The size of the U-shaped grooves 34 is larger than the long enlarging head 36. The long enlarging head 36 is movably installed in the U-shaped grooves 34, so that the long enlarging head 36 can move slightly in the U-shaped grooves 34, so that the M-shaped metal clip 3 rotates around the long connecting plate 4. A limiting strip is provided at the end of the U-shaped groove 34, and the long enlarging head 36 is limited by the limiting strip to prevent the long enlarging head 36 from detaching from the U-shaped grooves 34 during the movement, thereby affecting the stability of the ventilation unit operation.

[0061] like Figures 1 to 6As shown, a return spring 37 is provided inside the M-shaped metal clip 3. One end of the return spring 37 is fixed at the center position of the inner top surface of the M-shaped metal clip 3, and the other end of the return spring 37 is fixed on the end surface of the long connecting plate 4, that is, the lower end of the return spring 37 located above the long connecting plate 4 is fixed on the upper end surface of the long connecting plate 4, and the upper end of the return spring 37 located below the long connecting plate 4 is fixed on the lower end surface of the long connecting plate 4; when the M-shaped metal clip 3 rotates, the M-shaped metal clip 3 can be restored to its initial position through the elasticity of the return spring 37 and the M-shaped metal clip 3 itself; a first connecting rod 31 is attached to the outer wall of the M-shaped metal clip 3, and the first connecting rod 31 is fixed to the outside of the M-shaped metal clip 3 by means of a buckle or welding. One end of the first connecting rod 31 is fixed at the position of the U-shaped groove 34 notch on the long magnifying head 36. A driving component is connected to the first connecting rod 31 through a gear set and a rack, and the M-shaped metal clip 3 is rotated around the long connecting plate 4 through the driving component;

[0062] As Figures 4 to 6 As shown, four second connecting side plates 42 are vertically arranged between the noise reduction component and the long connecting plate 4. Each second connecting side plate 42 is parallel to the first connecting side plate 41 and is fixed on the structural column. A driving component is installed between the two second connecting side plates 42 on the same side of the long connecting plate 4. The driving component includes a rotating rod 33. The axis of the rotating rod 33 is perpendicular to the center line of the second connecting side plate 42 in the length direction. A driving motor is connected to the rotating rod 33 near its end. The driving motor is connected to the battery module 18 or the indoor power supply through a wire. The rotating rod 33 is rotated by the driving motor. A cam 35 is connected to the rotating rod 33. A second connecting rod 32 is arranged on the upper end of the first connecting rod 31. In this embodiment, one second connecting rod 32 is arranged on the upper ends of the two first connecting rods 31. The outer wall of the second connecting rod 32 is in contact with the outer wall of the cam 35. The rotating rod 33 is rotated by the driving motor, the rotating rod 33 drives the cam 35 to rotate, the cam 35 pushes the second connecting rod 32, and the M-shaped metal clip 3 is rotated around the long connecting plate 4 through the second connecting rod 32.

[0063] As Figures 1 to 11As shown in the figure, folding bellows 39 are respectively arranged on the left and right side surfaces of the long connecting plate 4 inside the M-shaped metal clip 3. The folding bellows 39 are leather bellows. The folding bellows 39 include a first folding bellows and a second folding bellows. First clamping plates 38 are arranged on both sides of the first folding bellows and the second folding bellows, and the connection area between the folding bellows 39 and the first clamping plates 38 is hermetically connected. One end heads of the two first clamping plates 38 on the same folding bellows 39 are rotatably connected. This end head is close to the clip opening position of the M-shaped metal clip 3. And the first clamping plates 38 on the first folding bellows and the second folding bellows close to the long connecting plate 4 are fixed on the side surface of the long connecting plate 4. The first clamping plates 38 installed on the other side of the first folding bellows and the second folding bellows are fixed on the inner wall of the M-shaped metal clip 3. And on the end surface of the inner side of the M-shaped metal clip 3 where the first clamping plate 38 is fixed, a guide groove is arranged along the extension direction of the first connecting rod 31. A guide block is arranged on the first clamping plate 38 close to the inside of the M-shaped metal clip 3. The guide block is slidably installed in the guide groove. When the M-shaped metal clip 3 rotates, the end heads of the two first clamping plates 38 on the first folding bellows away from the clip opening of the M-shaped metal clip 3 approach each other, compressing the first folding bellows, and then the first folding bellows exhausts air. Then the end heads of the two first clamping plates 38 on the second folding bellows away from the clip opening of the M-shaped metal clip 3 move away from each other, unfolding the second folding bellows on the same side of the long connecting plate 4 inside the M-shaped metal clip 3, and making the second folding bellows inhale air. An air inlet pipe and an air outlet pipe are arranged on both the first folding bellows and the second folding bellows, that is, the second ventilation hose 44 and the first ventilation hose 43. Gas one-way valves are arranged in the second ventilation hose 44 and the first ventilation hose 43. The port of the second ventilation hose 44 of the first folding bellows is arranged between the noise reduction component and the battery mounting plate 14. The port of the first ventilation hose 43 of the first folding bellows is arranged between the noise reduction component and the outer wall panel 2. The port of the second ventilation hose 44 of the second folding bellows is arranged on the outer wall panel 2. The port of the first ventilation hose 43 of the second folding bellows is arranged between the noise reduction component and the battery mounting plate 14. A third ventilation through hole 20 is arranged on the outer wall panel 2. A porous filter layer 21 is arranged in the third ventilation through hole 20. The outside of the porous filter layer 21 is flush with the outer wall of the outer wall panel 2. The port of the second ventilation hose 44 connecting the second folding bellows is connected in the third ventilation through hole 20 on the outer wall panel 2. And the number of the third ventilation through holes 20 arranged on the outer wall panel 2 is more than the number of the second ventilation hoses 44 connected to the folding bellows 39 close to the outer wall panel 2. Therefore, after the installation of this device is completed, there will be some third ventilation through holes 20 in which the second ventilation hoses 44 are not installed. A second ventilation through hole 19 is arranged on the battery mounting plate 14. A first ventilation through hole 11 is arranged on the inner wall panel 1. Through the linkage component, the first folding bellows on the same side end surface of the M-shaped metal clip 3 inhales air, the second folding bellows exhausts air, or the first folding bellows exhausts air, and the second folding bellows inhales air, so as to exchange the air outside the outer wall panel 2 and the air inside the inner wall panel 1.

[0064] Exemplarily, within two M-shaped metal clips 3 vertically located in the same plane on the long connecting plate 4, the first folding bellows are marked as folding bellows A and folding bellows C, and the second folding bellows are marked as folding bellows B and folding bellows D. Then, the ports of the second ventilation hoses 44 of folding bellows A and folding bellows C are arranged at positions close to the battery mounting plate 14, and the ports of the first ventilation hoses 43 of folding bellows A and folding bellows C are arranged between the noise reduction component and the outer wall panel 2; the ports of the second ventilation hoses 44 of folding bellows B and folding bellows D are arranged on the outer wall panel 2, and the ports of the first ventilation hoses 43 of folding bellows B and folding bellows D are arranged at positions close to the battery mounting plate 14. When the driving motor is started to work, the driving motor drives the cam 35 to rotate, the cam 35 pushes the second connecting rod 32 to move, and the second connecting rod 32 causes the M-shaped metal clip 3 to rotate, so as to compress folding bellows A and folding bellows D, and to expand folding bellows B and folding bellows C. Folding bellows A discharges the air inside it to the position between the noise reduction component and the outer wall panel 2 through the first ventilation hose 43, and folding bellows D discharges the air inside it to the position close to the battery mounting plate 14 through the first ventilation hose 43. At the same time, folding bellows C sucks the air at the position of the battery mounting plate 14 through the second ventilation hose 44, and folding bellows B sucks the air outside the outer wall panel 2 through the second ventilation hose 44. The air near the battery mounting plate 14 exchanges air with the indoor air through the second ventilation through-hole 19 and the first ventilation through-hole 11 on the inner wall panel 1, realizing the exchange of indoor and outdoor air. During the elastic reset process of the M-shaped metal clip 3 through the return spring 37 and the M-shaped metal clip 3 itself, folding bellows A and folding bellows D inhale air, and folding bellows B and folding bellows C exhale air.

[0065] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 9 and Figure 10 shown, a heat insulation curtain 15 is arranged between the noise reduction component and the battery mounting plate 14. There is a gap less than 15 mm between the bottom end of the heat insulation curtain 15 and the floor beam or floor slab, and there are gaps less than 15 mm between the left end and the right end face of the heat insulation curtain 15 and the structural column respectively. The first ventilation hose 43 and the second ventilation hose 44 are installed at this gap, ensuring that when the heat insulation curtain 15 is fully unfolded, the heat exchange rate between the indoor and outdoor of the building can be effectively reduced. The material of the heat insulation curtain 15 is one of multi-layer aluminum-tin foil composite material, aerogel composite heat insulation felt and ethylene-tetrafluoroethylene copolymer.

[0066] Preferably, a fourth ventilation through-hole 22 is arranged on the heat insulation curtain 15, facilitating the air circulation between the battery mounting plate 14 and the noise reduction component.

[0067] Further, the heat insulation curtain 15 is arranged in multiple sections. As Figure 10 shown, all the heat insulation curtains 15 are arranged coplanarly, and a gap of less than 50 mm is reserved between adjacent ends of the heat insulation curtains 15 for threading the first ventilation hose 43 and the second ventilation hose 44.

[0068] Further, a back plate 56 is arranged at the reserved gap between adjacent ends of the heat insulation curtains 15. As Figure 12 shown, an arc-shaped fixing member 55 is arranged on one side end face of the back plate 56. The arc-shaped fixing member 55 is an arc-shaped fixing plastic card plate. The arc-shaped fixing member 55 is used to fix the first ventilation hose 43 and the second ventilation hose 44. A second bottom plate 57 is arranged on the bottom end face of the back plate 56. The second bottom plate 57 is a flat structure with wide ends and narrow middle. The two end positions of the second bottom plate 57 are fixed to the floor beam or floor slab by self-tapping screws.

[0069] A winding and unwinding assembly is arranged at the upper end of the heat insulation curtain 15. The winding and unwinding assembly is installed on the floor beam or floor slab between the noise reduction assembly and the battery mounting plate 14; the winding and unwinding assembly includes a reel. The reel is horizontally installed on the floor beam or floor slab between the noise reduction assembly and the battery mounting plate 14. A winding and unwinding motor is connected to the reel. The winding and unwinding motor is connected to the battery module 18 or the indoor power supply through a wire. The top end of the heat insulation curtain 15 is fixedly connected to the reel. By operating the winding and unwinding motor, the reel rotates to wind up or unwind the heat insulation curtain 15.

[0070] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8As shown in the figure, the noise reduction component includes a first noise reduction thin film plate 51 and a second noise reduction thin film plate 52. The first noise reduction thin film plate 51 and the second noise reduction thin film plate 52 are respectively parallel to the outer wall panel 2, and after the first noise reduction thin film plate 51 and the second noise reduction thin film plate 52 are installed, they do not affect the rotation of the cam 35. In this embodiment, there are multiple first noise reduction thin film plates 51 and multiple second noise reduction thin film plates 52. When the multiple first noise reduction thin film plates 51 and the multiple second noise reduction thin film plates 52 are installed, enough width is reserved at the cam 35 to not interfere with the rotation of the cam 35. The first noise reduction thin film plate 51 and the second noise reduction thin film plate 52 are symmetrically installed on both sides of the ventilation part, or the first noise reduction thin film plate 51 and the second noise reduction thin film plate 52 are arranged in a staggered manner on both sides of the ventilation part. The distance between the first noise reduction thin film plate 51 and the second noise reduction thin film plate 52 ranges from 8 cm to 20 cm, so that an effective air layer is formed between the first noise reduction thin film plate 51 and the second noise reduction thin film plate 52, which has a blocking and attenuation effect on sound waves, thereby enhancing the noise reduction effect of the device and preventing interference between the thin film plates caused by too small a distance or reduction of the noise reduction effect due to too large a distance; the first noise reduction thin film plate 51 is arranged at a position close to the outer wall panel 2; the second noise reduction thin film plate 52 is arranged at a position close to the battery installation plate 14; a first bottom plate 54 is connected to the bottom ends of the first noise reduction thin film plate 51 and the second noise reduction thin film plate 52, and the first bottom plate 54 is fixed to the floor beam or floor slab by screws. Two second clamping plates 53 are symmetrically arranged on the upper end surface of the first bottom plate 54, and the first noise reduction thin film plate 51 and the second noise reduction thin film plate 52 are fixed by riveting or bonding connection between the two second clamping plates 53. The external noise is absorbed by the first noise reduction thin film plate 51 and the second noise reduction thin film plate 52. The first noise reduction thin film plate 51 is mainly used for absorbing medium and low frequency noise, and the second noise reduction thin film plate 52 is mainly used for absorbing high frequency noise; at the same time, under the action of the return spring 37 and the elasticity of the M-shaped metal clip 3 itself, the M-shaped metal clip 3 has a tendency to return to its initial position. During the reset process, the second connecting rod 32 will swing slightly along with the M-shaped metal clip 3. At this time, the second connecting rod 32 will hit the first noise reduction thin film plate 51 or the second noise reduction thin film plate 52, and the force of the second connecting rod 32 hitting the first noise reduction thin film plate 51 or the second noise reduction thin film plate 52 is less than 2 N. When the second connecting rod 32 hits the first noise reduction thin film plate 51 or the second noise reduction thin film plate 52, sound waves will be generated, and the sound waves will conduct in the air to interfere with the noise transmitted from the outside to the inside of the room, further assisting in noise reduction;

[0071] Meanwhile, when installing the first noise reduction film plate 51 and the second noise reduction film plate 52, a sufficiently large spacing can also be reserved between the first noise reduction film plate 51 and the second noise reduction film plate 52. During the rotation of the M-shaped metal clip 3 or the reset process under the action of the reset spring 37, the second connecting rod 32 will not hit the first noise reduction film plate 51 and the second noise reduction film plate 52, thus increasing the service life of the first noise reduction film plate 51 and the second noise reduction film plate 52.

[0072] In this embodiment, the first noise reduction film plate 51 is a natural rubber film plate with a thickness range of 1 mm to 4 mm and a porosity of 20%, which can effectively absorb noise in the medium and low frequency bands; the second noise reduction film plate 52 is a polyester film plate with a thickness range of 0.1 mm to 1 mm and a porosity of 40%, which has a good attenuation effect on high frequency band noise and also helps with sound scattering and interference, further enhancing the noise reduction effect and the flexibility and adaptability of the device.

[0073] The working principle is further used to explain this exterior wall structure as follows:

[0074] For the summer environment, when the indoor temperature is high and the outdoor temperature is low, the reel is rotated by the winding and unwinding motor to retract the heat insulation curtain 15, and the heat insulation curtain 15 is kept in this state all the time. Then, the indoor and outdoor air is exchanged in the following two ways;

[0075] One way is to utilize the natural state to allow the high-temperature air indoors to enter the position where the battery mounting plate 14 is located through the first ventilation through hole 11, then flow to the position of the outer wall panel 2 through the second ventilation hole 19, and flow outdoors through the third ventilation through hole 20 on the outer wall panel 2. The low-temperature air outdoors flows to the battery mounting plate 14 through the third ventilation through hole 20, then flows to the position of the inner wall panel 1 through the second ventilation hole 19, and finally enters the room through the first ventilation through hole 11 to achieve the air exchange between the room and the outdoors;

[0076] Another way is to rotate the rotating rod 33 by driving the motor. Then, the cam 35 will cause the M-shaped metal clip 3 to rotate around the long connecting plate 4. The folding bellows A and the folding bellows D are compressed, and the folding bellows B and the folding bellows C are unfolded. The folding bellows A discharges the air inside it to the position between the noise reduction component and the outer wall panel 2 through the first ventilation hose 43. The folding bellows D releases the air inside it to the area near the interior of the room through the first ventilation hose 43. At the same time, the folding bellows C sucks the air in the area near the interior of the room through the second ventilation hose 44, and the folding bellows B sucks the air outside the outer wall panel 2 through the second ventilation hose 44, thereby forming a heat exchange between the interior and the exterior of the room, which helps to reduce the temperature inside the room and thus reduce the indoor cooling load. When the drive motor is working, if the battery module 18 powers the drive motor, heat energy will be generated, and the drive motor will also generate heat energy. These two parts of heat energy mainly accumulate between the battery mounting plate 14 and the inner wall panel 1. The two parts of heat energy will also be exchanged with the lower-temperature air outside by the folding bellows 39. At the same time, the folding bellows 39 will also suck in the colder air outside and release it between the battery mounting plate 14 and the second noise reduction film plate 52. A part of the heat will be exchanged between the second noise reduction film plate 52 and the inner wall panel 1. Through this exterior wall structure, the heat exchange between the interior and the exterior of the room is realized, which helps to reduce the indoor cooling load. When the indoor temperature is close to the outdoor temperature, by starting the winding and unwinding motor and keeping the drive motor off, the heat insulation curtain 15 is unfolded, so that the indoor and outdoor air temperatures hardly exchange any more.

[0077] For the winter environment, when the indoor temperature is high and the outdoor temperature is low, the winding and unwinding motor is turned on and the drive motor is kept off, and the heat insulation curtain 15 is unfolded to weaken the heat exchange between the interior and the exterior of the room to reduce the indoor heat load.
