Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a through-the-wall machine. Background Art

[0002] With advancements in construction technology and growing environmental awareness, new buildings are increasingly adopting new lightweight materials, significantly reducing wall thickness. This trend places new demands on the installation of building equipment, particularly air conditioning systems. Traditional through-the-wall air conditioners (PTACs), due to their thickness, protrude from the wall surface when installed in thin-wall environments, affecting the building's aesthetics and space utilization.

[0003] At the same time, users have increasingly higher requirements for the noise level of air conditioners during operation. Existing PTAC air conditioners generate a lot of noise during operation, especially when the compressor and fan are working, which makes it difficult to meet users' demand for a low-noise environment.

[0004] Traditional through-the-wall air conditioners have a rectangular appearance, with the indoor and outdoor air ducts arranged in a horizontal front-to-back structure. The entire machine is thick and cannot meet the thinning walls of new buildings. The inside and outside will protrude from the wall, affecting the building's aesthetics and space utilization.

[0005] Due to the large thickness of the through-the-wall air conditioner in the prior art, when installed in a thin wall environment, the inner and outer sides will protrude from the wall, affecting the aesthetics and space utilization of the building. Therefore, the present invention studies and designs a through-the-wall air conditioner. Summary of the Invention

[0031] The wall penetration machine provided by the present invention has the following beneficial effects:

[0032] 1.

[0034] 3. The present invention further arranges the electrical box component and the indoor heat exchange component in an upper and lower layout, so that the electrical box and the indoor heat exchange component will not interfere with each other, releasing the horizontal space originally occupied by the electrical box, so that the evaporator can occupy more space, thereby improving the heat exchange efficiency; and the electrical box is arranged above or below the indoor heat exchange component, and horizontally relative to the outdoor heat exchange component, which can further utilize the part of the area where the outdoor heat exchange component is horizontally opposite to the indoor heat exchange component and vertically opposite to the indoor heat exchange component.

[0035] 4. The present invention can further separate the outdoor heat exchange component, the outdoor fan and the indoor electrical box through the provision of a middle partition, and can accommodate at least part of the structure of the electrical box component through the first groove formed on the middle partition at a position relative to the electrical box component, and at the same time form a first protrusion on the side of the middle partition facing the outdoor heat exchange component, and form a second and third grooves on both sides of the first protrusion respectively, thereby forming a double-groove channel.

[0037] 6. The present invention further provides a sound insulation layer on the side of the central partition facing the electrical box and / or the side facing the outdoor air duct components, effectively isolating the outdoor from the indoor environment to achieve optimal noise reduction. Furthermore, for through-the-wall units, the present invention employs an extended, multi-fold, double-row evaporator design. This increases fin length and surface area, while also utilizing a multi-fold evaporator that closely aligns with the crossflow blades, effectively reducing the air duct and evaporator space, improving heat exchange capacity, and reducing the number of fin rows to reduce wind resistance and increase air flow.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0052] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0055] like Figure 1-9 As shown, the present invention provides a wall penetration machine, which includes:

[0056] The casing 100, the indoor heat exchange component 70 and the outdoor heat exchange component 30, the casing 100 includes an indoor partial casing 101 and an outdoor partial casing 102, the indoor heat exchange component 70 is arranged in the indoor partial casing 101, the outdoor heat exchange component 30 is arranged in the outdoor partial casing 102, and the indoor heat exchange component 70 is located above the outdoor heat exchange component 30, the indoor partial casing 101 and the outdoor partial casing 102 are connected as a whole to form an integrated air conditioner.

[0057] The present invention arranges the through-the-wall machine so that the indoor heat exchange component (located in the indoor partial casing) is located above the outdoor heat exchange component (located in the outdoor partial casing), so that the indoor heat exchange component and the outdoor heat exchange component can be arranged in an upper and lower manner. Compared with the method of horizontally arranging the indoor and outdoor heat exchange components in the prior art, the thickness of the through-the-wall machine in the horizontal direction can be effectively reduced, and it can be suitable for installation in a thin-wall environment. The inner and outer sides of the through-the-wall machine will not protrude from the wall surface, thereby improving the aesthetics and space utilization of the building, and effectively solving the problem in the prior art that the through-the-wall machine air conditioner has a large horizontal thickness and, after installation in a thin-wall environment, the inner and outer sides will protrude from the wall surface, affecting the aesthetics and space utilization of the building.

[0058] The invention is to develop an ultra-thin, efficient, silent, through-the-wall air conditioner that can reduce the thickness of the air conditioner to 12-16 inches while maintaining cooling / heating efficiency and performance, thereby avoiding protrusion from the wall and improving the aesthetics of the building and space utilization.

[0059] In some embodiments,

[0060] It also includes an indoor air duct component 60 and an outdoor air duct component 80, the indoor air duct component 60 is arranged in the indoor side part casing 101, and the outdoor air duct component 80 is arranged in the outdoor side part casing 102, the indoor air duct component 60 is provided with an indoor fan 64, and the outdoor air duct component 80 is provided with an outdoor fan 801, the indoor fan 64 is arranged opposite to the indoor heat exchange component 70, and the outdoor fan 801 is arranged opposite to the outdoor heat exchange component 30, the indoor air duct component 60 is located above the outdoor air duct component 80, and the indoor fan 64 is located above the outdoor fan 801.

[0061] The present invention further arranges the indoor duct component and the outdoor duct component in an upper and lower layout (preferably the indoor duct component is located above the outdoor duct component), and the indoor fan is arranged in the indoor duct component, and the outdoor fan is arranged in the outdoor duct component, so that the indoor duct and the outdoor duct are staggered in the vertical direction, and the indoor fan and the outdoor fan are staggered in the vertical direction. Compared with the prior art method of horizontally arranging the indoor and outdoor duct components and the indoor and outdoor fans of horizontal components, the thickness of the wall-penetrating machine in the horizontal direction can be further effectively reduced, and it can be further suitable for installation in a thin wall environment, so that the inner and outer sides of the wall-penetrating machine will not protrude from the wall surface, thereby further improving the beauty and space utilization of the building.

[0062] like Figure 5 As shown, the present invention provides an L-shaped ultra-thin fully embedded high-efficiency silent wall-penetrating machine, which consists of a chassis component, a compressor component, a condenser component, an outdoor air duct, an evaporator component, an indoor air duct, a middle partition, a support plate, an electrical box component and an appearance component.

[0063] The body of the invention is thin and suitable for thinning walls of new buildings.

[0064] like Figure 2 、 Figure 3 As shown, the overall appearance of the machine is L-shaped, and the indoor side air duct component 60 and the outdoor side air duct component 80 adopt an upper and lower vertical layout. The indoor and outdoor air ducts are staggered, which releases the thickness space of the entire machine, thereby thinning the thickness of the machine body to meet the thinning wall requirements of new buildings, reduce installation impact, and improve aesthetics.

[0065] like Figure 2 As shown, the indoor side air duct component 60 adopts top air intake and front air outlet, and the indoor side air duct component 60 adopts a cross-flow air duct.

[0066] In some embodiments,

[0067] The indoor partial casing 101 is located on the inner side of the wall, and the outdoor partial casing 102 is located inside the wall (i.e., preferably, the outdoor partial casing is located inside the wall hole). In a vertical plane projection, the entire structure of the indoor heat exchange component 70 is located above the entire structure of the outdoor heat exchange component 30. In a horizontal plane projection, the indoor heat exchange component 70 and the outdoor heat exchange component 30 have at least partial structural overlap.

[0068] The entire structure of the indoor air duct component 60 is located above the entire structure of the outdoor air duct component 80 in a vertical plane projection, and the indoor air duct component 60 and the outdoor air duct component 80 have at least a partial structural overlap in a horizontal plane projection.

[0069] In the vertical plane projection, the overall structure of the indoor fan 64 is located above the overall structure of the outdoor fan 801 , and in the horizontal plane projection, the indoor fan 64 and the outdoor fan 801 have at least partial structural overlap.

[0070] This is the preferred structural form of the indoor heat exchange component, outdoor heat exchange component, indoor air duct component, outdoor air duct component, and indoor fan and outdoor fan of the present invention, so that the overall structure of the indoor heat exchange component is located above the overall structure of the outdoor heat exchange component, and preferably there is an overlapping part between the two inside the horizontal plane projection surface, and the overall structure of the indoor air duct component is located above the overall structure of the outdoor air duct component (part of the structure (bent part) of the outdoor heat exchange component can be further retracted into the indoor casing, making the structure more compact and further reducing the thickness in the horizontal direction), and preferably there is a partial structural overlap between the two within the horizontal plane projection surface. (Part of the structure of the outdoor air duct can be further retracted into the indoor casing, making the structure more compact and further reducing the thickness in the horizontal direction); the overall structure of the indoor fan is located above the overall structure of the outdoor fan, and preferably there is a partial structural overlap between the two in the horizontal projection plane (part of the structure of the outdoor fan can be further retracted into the indoor casing, making the structure more compact and further reducing the thickness in the horizontal direction), thereby further effectively reducing the thickness of the through-wall machine in the horizontal direction, and further being suitable for installation in a thin-wall environment, without causing the inner and outer sides of the through-wall machine to protrude particularly from the wall, thereby further improving the aesthetics and space utilization of the building.

[0071] In some embodiments,

[0072] The vertical height of the indoor side part housing 101 is higher than the vertical height of the outdoor side part housing 102, so that on the thickness plane of the wall (the normal direction perpendicular to the wall is the thickness direction of the wall, that is, the thickness normal, and the vertical plane containing the thickness normal is the thickness plane, that is, Figure 3 The through-the-wall machine has an "L"-shaped structure in the projection surface of the plane), and the indoor heat exchange component 70, the indoor air duct component 60 and the indoor fan 64 are arranged inside the part of the indoor part casing 101 that is vertically higher than the outdoor part casing 102.

[0073] This is a further preferred structural form of the indoor side partial casing and the outdoor side partial casing of the present invention. The height of the indoor side partial casing is higher than that of the outdoor side partial casing, forming an "L"-shaped wall-penetrating machine. The indoor side heat exchange component, the indoor side air duct component and the indoor side fan can be arranged in the raised part of the indoor side partial casing, so that the indoor heat exchange + air duct structure arranged on the horizontal side of the outdoor air duct component in the original technology is arranged above, thereby effectively reducing the thickness of the wall-penetrating machine in the horizontal direction, and further being suitable for installation in a thin wall environment, without making the inner and outer sides of the wall-penetrating machine protrude particularly from the wall surface, further improving the aesthetics and space utilization of the building.

[0074] In some embodiments,

[0075] It also includes an electrical box component 90, which is arranged in the indoor part of the casing 101. The electrical box component 90 is located below or above the indoor heat exchange component 70, and the electrical box component 90 and the outdoor heat exchange component 30 are arranged horizontally relative to each other.

[0076] The present invention further arranges the electrical box component and the indoor heat exchange component in an upper and lower layout, so that the electrical box and the indoor heat exchange component will not interfere with each other, releasing the horizontal space originally occupied by the electrical box, allowing the evaporator to occupy more space, thereby improving the heat exchange efficiency; and the electrical box is arranged above or below the indoor heat exchange component, and horizontally relative to the outdoor heat exchange component, which can further utilize the part of the area where the outdoor heat exchange component is horizontally opposite to the indoor heat exchange component and vertically opposite to the indoor heat exchange component. The electrical box component is arranged in this part, which can further effectively utilize the space, further improve the space utilization rate, and further reduce the overall horizontal thickness of the wall-penetrating machine.

[0077] like Figure 3 As shown, the indoor air duct component 60 adopts a cross-flow air duct and is designed on the upper part of the machine (above the outdoor air duct component 80). Figure 4As shown, the electrical box component 90 and the indoor heat exchange component 70 are arranged vertically, changing the traditional horizontal layout to ensure that the two do not interfere with each other. This frees up the horizontal space originally occupied by the electrical box, allowing the indoor heat exchange component 70 (evaporator component) to occupy more space, thereby improving heat exchange efficiency. This increases the windward area, improves the evaporator's heat exchange efficiency, and enhances the overall performance of the unit.

[0078] In some embodiments,

[0079] When the indoor air duct component 60 and the outdoor air duct component 80 are also included:

[0080] The indoor heat exchange component 70 and the indoor air duct component 60 are arranged opposite to each other in the vertical direction, the outdoor air duct component 80 and the outdoor heat exchange component 30 are arranged opposite to each other in the horizontal direction, and the electrical box component 90 is located directly below the indoor air duct component 60, and the electrical box component 90 and the outdoor air duct component 80 are arranged at intervals in the horizontal direction.

[0081] The electrical box component of the present invention is preferably located directly below the indoor air duct component, and is horizontally opposite to and spaced apart from the outdoor air duct component, so that the area horizontally opposite to the outdoor heat exchange component and vertically below the indoor heat exchange component can be further utilized. By arranging the electrical box component in this area, the space can be further effectively utilized, the space utilization rate can be further improved, and the overall horizontal thickness of the wall-penetrating machine can be further reduced; and the horizontal space originally occupied by the electrical box can be further released, so that the evaporator can occupy more space, thereby improving the heat exchange efficiency.

[0082] In some embodiments,

[0083] When the indoor air duct component 60 and the outdoor air duct component 80 are also included:

[0084] The wall-penetrating machine also includes a middle partition 81, which is arranged in the casing 100 and is located between the electrical box component 90 and the outdoor air duct component 80, and a first groove 811 is formed on the middle partition 81 at a position opposite to the electrical box component 90. The first groove 811 can accommodate at least part of the structure of the electrical box component 90, so that the middle partition 81 forms a first protrusion 813 at this position and toward the direction of the outdoor air duct component 80, and at the same time, the middle partition 81 is located on one side of the first protrusion to form a second groove 815, and the middle partition 81 is located on the other side of the first protrusion to form a third groove 816.

[0085] The present invention further separates the outdoor heat exchange component, the outdoor fan and the indoor electrical box through the provision of a middle partition, and can accommodate at least part of the structure of the electrical box component through a first groove formed on the middle partition relative to the electrical box component, and at the same time forms a first protrusion on the side of the middle partition facing the outdoor heat exchange component, and forms a second and third grooves on both sides of the first protrusion, thereby forming a double-groove channel. The double-groove channel can disperse the airflow into two paths, so that the cross-sectional area of each channel is increased, avoiding the occurrence of narrow areas inside the air duct, and avoiding local high pressure or high-speed flow when the airflow passes through, thereby effectively reducing noise.

[0086] The air inlet cross-section of the outdoor air duct of the present invention is increased, and the air flow speed is increased, thereby reducing wind resistance and noise.

[0087] like Figure 7 、 8 As shown, by changing the parallel front-to-back layout of the indoor air duct component 60 and the outdoor air duct component 80 to an up-and-down vertical layout, the electrical box component 90 is placed in the middle of the machine, which does not affect the air intake on both sides of the outer air duct, increases the cross-sectional area of the air duct on the air inlet side of the outdoor air duct component 80, avoids narrow areas inside the air duct, and avoids local high pressure or high-speed flow when the airflow passes through, thereby reducing noise.

[0088] The heat sink 91 of the electrical box component 90 can extend into the air inlet side of the outdoor air duct component 80 through the radiator mounting hole 812 in the middle partition 81, which is beneficial to the heat exchange of the controller components, improves the energy efficiency of the whole machine, and saves energy and electricity.

[0089] The middle partition 81 of the present invention has a double-groove channel (including a second groove 815 and a third groove 816). The double-groove channel disperses the airflow into two paths, and the cross-sectional area of each channel is increased, avoiding narrow areas inside the air duct and avoiding local high pressure or high-speed flow when the airflow passes through, thereby reducing noise.

[0090] In some embodiments,

[0091] The middle partition 81 is disposed in the indoor partial housing 101 and is located vertically below the indoor air duct component 60, so that along the thickness direction of the wall, the size of the space occupied by the electrical box component 90 is smaller than the size of the space occupied by the indoor air duct component 60;

[0092] When an outdoor fan 801 is also included, the wall-penetrating machine also includes an outdoor motor 802, which is connected to the outdoor fan 801 to drive the outdoor fan 801 to rotate, and at least part of the structure of the outdoor motor 802 and at least part of the structure of the outdoor fan 801 are located vertically below the indoor air duct component 60.

[0093] The present invention further arranges a middle partition in the indoor side part of the casing and is located below the indoor side air duct component in the vertical direction, so that along the thickness direction of the wall, the size of the space occupied by the electrical box component is smaller than the size of the space occupied by the indoor side air duct component, so that the electrical box requiring smaller space does not have to occupy a large space, and the position of the middle partition is moved vertically below the indoor air duct component, rather than at the position where the indoor casing is connected to the wall, so that the outdoor side air duct, heat exchange components, fan and other structures requiring larger space occupy part of the space in the indoor casing, which can further reasonably and effectively utilize the space, further reduce the overall horizontal thickness of the wall-penetrating machine, etc., make the volume more compact, further improve the space utilization rate, and be more beautiful.

[0094] In some embodiments,

[0095] A sound insulation layer 814 is further provided on the side of the middle partition 81 facing the electrical box component 90 , and / or a sound insulation layer 814 is further provided on the side of the middle partition 81 facing the outdoor air duct component 80 .

[0096] The present invention further provides a sound insulation layer on the side of the middle partition facing the electrical box and / or the side facing the outdoor air duct component, thereby effectively isolating the outdoor side from the indoor side to achieve the best noise reduction effect.

[0097] In some embodiments,

[0098] The indoor heat exchange component 70 is a multi-fold heat exchanger, and the indoor heat exchange component 70 has more than two rows of heat exchangers. The multi-fold section refers to the indoor heat exchange component 70 consisting of multiple folded heat exchange parts in a cross section perpendicular to the axial extension direction of the indoor heat exchange component 70. The two or more rows refers to the indoor heat exchange component 70 consisting of at least two rows of heat exchange parts along the axial extension direction of the indoor heat exchange component 70.

[0099] The indoor fan 64 is a cross-flow fan.

[0100] The present invention further adopts an extended, multi-fold, double-row evaporator design for wall-penetrating machines. On the one hand, it can increase the fin length and expand the surface area. On the other hand, the multi-fold evaporator is used to make the evaporator close to the cross-flow fan blades, which can effectively reduce the air duct and evaporator space, improve heat exchange capacity, reduce the number of fin rows, reduce wind resistance, and increase air flow.

[0101] The invention has long indoor side air duct blades, a large windward area of the evaporator, a small number of evaporator rows, small wind resistance, large air volume, high evaporator heat exchange efficiency and good performance.

[0102] like Figure 6 As shown, the indoor heat exchange component 70 adopts an extended, multi-fold, double-row evaporator design, which changes the traditional through-the-wall evaporator into a shorter and thicker rectangular structure, greatly expands the surface area of the evaporator fins, and adopts a multi-fold evaporator. The evaporator is close to the cross-flow fan blades, which can effectively reduce the air duct and evaporator space, improve the heat exchange capacity, reduce the number of fin rows, reduce wind resistance, and increase air flow.

[0103] The indoor side air duct of the present invention has low wind resistance and low noise, thereby improving user experience.

[0104] like Figure 4 、 6 As shown, the indoor air duct component 60 adopts a cross-flow duct, and the electrical box component 90 and the indoor heat exchange component 70 are arranged vertically instead of parallel horizontally. This frees up space in the evaporator component, thereby increasing the windward area by 33%. Furthermore, the number of rows of indoor heat exchange components 70 has been reduced from three to two, and the fin thickness has been reduced by 33%. This significantly reduces evaporator wind resistance, allowing the same air volume at lower speeds, thereby reducing overall unit noise, with air supply noise significantly reduced by 10dB(A).

[0105] The invention improvement of the present invention is:

[0106] 1. L-shaped design: The indoor and outdoor side air ducts are arranged vertically up and down, and the indoor and outdoor ducts are staggered, which is suitable for modern thin-walled buildings. It saves space, adapts to modern thin-walled buildings, reduces installation impact, and improves aesthetics.

[0107] 2. Vertical layout design: The electrical box and evaporator are arranged vertically to ensure that they do not interfere with each other, freeing up the horizontal space originally occupied by the electrical box, allowing the evaporator to occupy more space, thereby improving heat exchange efficiency.

[0108] 3. The outdoor side partition has a double-groove channel, which disperses the airflow into two paths. The cross-sectional area of each channel is increased, avoiding narrow areas inside the air duct and avoiding local high pressure or high-speed flow when the airflow passes through, thereby reducing noise.

[0109] 4. A sound insulation layer is set between the indoor and outdoor sides of the casing, and sound insulation materials can be added to isolate the outdoor side from the indoor side to achieve the best noise reduction effect.

[0110] 5. Adopt extended, multi-fold, double-row evaporator design: on the one hand, increase the fin length and expand the surface area, adopt multi-fold evaporator, the evaporator is close to the cross-flow fan blade, which can effectively reduce the air duct and evaporator space, improve heat exchange capacity, reduce the number of fin rows, reduce wind resistance and increase air flow.

[0111] The present invention can effectively solve the following technical problems:

[0112] 1. Solve the problem that the wall penetration machine has a thick body and cannot fit the thinner walls of new buildings.

[0113] Since traditional through-the-wall machines have a rectangular appearance, the indoor and outdoor air ducts are arranged in a horizontal front-to-back structure. The overall body of the machine is thick and cannot meet the thinning wall requirements of new buildings. The inside and outside will protrude from the wall, affecting the building's aesthetics and space utilization.

[0114] 2. Effectively solve the problems of short indoor side air duct blades, small evaporator windward area, large number of evaporator rows, large wind resistance, small air volume, low evaporator heat exchange efficiency and poor performance.

[0115] Because the electrical box and evaporator of traditional through-the-wall heat exchangers are arranged horizontally and parallel to each other, the overall length of the heat exchanger is limited by the standard wall hole dimensions. Therefore, the electrical box space occupies the evaporator length, making it impossible to lengthen the evaporator and increase its windward area. When the evaporator length is shortened to achieve the same cooling capacity, the number of rows increases, which increases wind resistance and reduces heat exchange efficiency.

[0116] 3. Effectively solve the problem of large wind resistance and noise in the indoor side air duct, which reduces the user experience.

[0117] Since the electrical box and evaporator of traditional through-the-wall units are arranged horizontally in parallel, the windward area of the evaporator tubes is reduced. For products with the same cooling capacity, the number of evaporator rows needs to be increased, which increases wind resistance and poor airflow. At the same time, it generates loud noise, which has a negative impact on the acoustic comfort of the indoor environment, and thus affects the user's daily life or work efficiency.

[0118] The beneficial effects of the present invention are as follows:

[0119] 1. The body of the present invention is thin and suitable for thinning walls of new buildings.

[0120] The present invention changes the indoor and outdoor air ducts from a parallel front-to-back layout to an up-and-down vertical layout, freeing up thickness space for the entire machine, thereby reducing the size of the machine body and meeting the requirements of thinning walls in new buildings.

[0121] 2. The indoor side air duct of the present invention has long blades, a large windward area of the evaporator, a small number of evaporator rows, small wind resistance, large air volume, high evaporator heat exchange efficiency and good performance.

[0122] The present invention changes the layout of the electrical box and evaporator from parallel horizontal to vertical, freeing up the length of the evaporator, thereby increasing the windward area, improving the evaporator's heat exchange efficiency, and enhancing the overall performance of the machine.

[0123] 3. The indoor side air duct of the present invention has low wind resistance and low noise, which improves the user experience.

[0124] The present invention changes the layout of the electrical box and evaporator from parallel horizontal to vertical, freeing up the length of the evaporator, thereby increasing the windward area, reducing the wind resistance of the evaporator, and lowering the noise of the entire machine.

[0125] 4. The air inlet cross-section of the outdoor air duct of the present invention is increased, which increases the air flow speed, thereby reducing wind resistance and noise.

[0126] By changing the indoor and outdoor side air ducts from a parallel front-to-back layout to an up-and-down vertical layout, the present invention can increase the cross-sectional area of the air duct on the air inlet side of the outdoor air duct, avoid narrow areas inside the air duct, and avoid local high pressure or high-speed flow when the airflow passes through, thereby reducing noise.

[0127] 5. The present invention helps reduce the transmission of outdoor noise to indoor noise by adding a sound insulation layer.

[0128] The present invention provides a sound insulation layer between the indoor side and the outdoor side of the casing, thereby increasing the isolation between the outdoor side and the indoor side of the sound insulation material to achieve the best noise reduction effect.
