Description

Technical Field

[0001] This invention relates to the field of air treatment, and more specifically to an air treatment device. Background Technology

[0002] As people's requirements for indoor environment continue to increase, various air treatment devices that can improve indoor air quality have emerged.

[0003] Typically, air handling equipment includes fresh air inlets, exhaust air inlets, return air inlets, and supply air outlets. A supply air path is formed from the fresh air inlet to the supply air outlet to bring outdoor air into the room, and an exhaust air path is formed from the return air inlet to the exhaust air outlet to exhaust indoor air. Furthermore, the air handling equipment is equipped with an internal circulation path, which allows the airflow entering from the return air inlet to flow directly back into the room from the supply air outlet.

[0004] In recent years, with the increasing demand for lower back dimensions in air handling units, the overall height of these units has been continuously reduced. This has led to a decrease in the volume of the gas flow chamber, severely impacting the performance of the air handling units. Therefore, further improvements to air handling units are expected in order to achieve lower back dimensions without compromising performance.

[0005] In the prior art, there is a known structure that uses a damper bracket to form a flow guide to smoothly guide gas into the air handling unit. However, this structure obstructs the airflow from the return air inlet, and the airflow direction changes after passing through the return air damper, further increasing pressure loss. Summary of the Invention

[0006] To address the problems existing in the prior art, the present invention provides an air handling device that can improve the performance of the air handling device while achieving a low-profile design.

[0007] One aspect of the present invention relates to an air handling device, comprising: a housing 110 having a top plate, a bottom plate spaced apart from the top plate and opposite to it, and a side plate connecting the periphery of the top plate and the periphery of the bottom plate; a fresh air inlet 112, a supply air inlet 113, a return air inlet 114, and an exhaust air inlet 115 disposed on the side plate; a first flow path LL1 from the fresh air inlet to the supply air inlet and a second flow path LL2 from the return air inlet to the exhaust air inlet formed inside the housing; and a total heat exchange core assembly 200 disposed within the housing, comprising a total heat exchange core body, the total heat exchange core body being respectively connected to the first flow path and the second flow path, wherein the housing and the... The total heat exchange core assembly has an air inlet cavity C2 communicating with the fresh air inlet, a return air cavity C4 communicating with the return air inlet, an air supply cavity C3 communicating with the air supply outlet, and an exhaust cavity C5 communicating with the exhaust outlet. A first partition unit 300 is provided between the air inlet cavity and the exhaust cavity. One side of the first partition unit is connected to the side plate of the housing, and the other side is connected to a corner of the total heat exchange core assembly. The surface of the first partition unit facing the air inlet cavity is formed as a first guide section 310. The first guide section includes at least a curved first guide section. The first guide section is configured to guide the air supplied from the fresh air inlet toward the windward side of the total heat exchange core assembly.

[0008] By providing a first partition unit between the air inlet and exhaust chambers, the surface of the first partition unit facing the air inlet is formed as a first guide section. The first guide section includes at least a curved first guide segment, which is configured to guide the air supplied from the fresh air inlet towards the windward side of the total heat exchange core assembly. This allows the guide section to be formed using the first partition unit, resulting in a simple structure. Furthermore, by designing the shape of the first guide segment, obstruction of the fresh air inlet and damper assembly can be avoided, reducing airflow resistance. Moreover, the first guide section can effectively improve airflow by directing airflow towards the total heat exchange core assembly. This achieves both a low-profile air handling unit and improved performance.

[0009] Ideally, the first guide section is formed by smoothly connecting multiple curves with different curvatures.

[0010] By setting the curve shape of the first guide section, the airflow can be smoothly guided, avoiding an increase in pressure loss.

[0011] Furthermore, the first guide section can also be formed by a curve with the same curvature.

[0012] In this way, the first guide section can be formed into a simple shape, which facilitates processing.

[0013] In addition, the first guide section also includes a straight second guide section. The angle between the second guide section and the side plate on which the fresh air inlet is provided is 90°. One end of the second guide section is smoothly connected to the end of the first guide section, and the other end is connected to the total heat exchange core assembly.

[0014] By forming the second guide section into a straight line, it can be easily matched with the core mounting rail, facilitating the assembly of the air handling equipment.

[0015] Ideally, a damper assembly 500 is provided at the fresh air inlet. The damper assembly includes a damper sleeve 501. At least a portion of the damper sleeve is located inside the fresh air inlet. In the airflow direction of the first flow path, the starting end of the first guide section is located closer to the fresh air inlet than the edge of the damper sleeve near the total heat exchange core assembly.

[0016] Because the starting end of the first guide section is located closer to the fresh air inlet than the edge of the damper sleeve near the total heat exchange core assembly, it can effectively guide the air flowing in from the fresh air inlet and avoid noise generation. The airflow exiting from the edge of the damper sleeve near the total heat exchange core assembly can be directly guided by the first guide section to the total heat exchange core body, thus avoiding the formation of eddies between the damper assembly and the first partition unit.

[0017] In addition, the first guide section also includes a third guide section, which is located on the opposite side of the first guide section and the second guide section. The third guide section is formed as a straight line or a curve and is smoothly connected to the starting end of the first guide section.

[0018] In addition, an airflow diffusion region S is formed between the first guide section and the side wall of the air valve assembly.

[0019] By setting up an airflow diffusion zone, airflow can be effectively improved, preventing increased pressure loss inside the machine, thereby further enhancing the performance of the air handling equipment.

[0020] Ideally, the surface of the first partition unit facing the exhaust cavity is formed as a second guide portion 320, which includes a straight guide portion parallel to the windward surface of the total heat exchange core assembly.

[0021] The surface of the first partition unit facing the exhaust cavity is formed as a second airflow guide, which includes a straight airflow guide parallel to the windward surface of the total heat exchange core assembly. This allows for further guidance of the airflow discharged from the total heat exchange core assembly, thereby improving the performance of the air handling equipment. Furthermore, the simple structure avoids turbulence, thus enhancing performance.

[0022] Furthermore, a second partition unit 400 is provided between the exhaust chamber and the supply chamber. One side of the second partition unit is connected to the side plate of the housing, and the other side is connected to a corner of the total heat exchange core assembly. In addition, the surface of the second partition unit facing the supply chamber is formed as a third guide portion 410, and the surface of the second partition unit facing the exhaust chamber is formed as a fourth guide portion 420.

[0023] Based on this structure, a guide section can be formed using the second partition unit, resulting in a simple structure. Furthermore, the third and fourth guide sections can be used to guide the airflow separately, effectively improving airflow and thus enhancing the performance of the air handling equipment.

[0067] The present invention will be further described below with reference to specific embodiments and accompanying drawings. More details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions and derivations based on actual application situations without departing from the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0068] (First Implementation)

[0069] Figure 1 This is a perspective view of an air handling device according to a first embodiment of the present invention, wherein the air handling device is positioned with its base plate facing upwards. Figure 1 As can be seen, a maintenance cover 111 is formed on the housing 110. This maintenance cover 111 is closably mounted on the housing 110, allowing the access ports on the housing 110 to be opened and closed. The maintenance cover 111 can be pivotally connected to the housing 110 via a structure such as a pivot, or it can be detachably or closably connected to the housing 110 in other ways known in the art. Typically, in the installed state, the portion of the housing 110 where the maintenance cover 111 is located is a downward-facing bottom plate. In this case, a cover anti-fall mechanism, such as a connecting rope, is preferably also provided. Preferably, the air handling unit 100 also includes an anti-fall strip 141, which, in the installed state, presses against the total heat exchange core assembly 200, thus preventing the total heat exchange core assembly 200 from accidentally falling when the maintenance cover 111 is opened for maintenance.

[0070] In addition to the aforementioned installation direction (normal installation), the air handling unit 100 can also be installed in reverse. To accommodate different installation directions, access ports and corresponding installation and maintenance covers 111 can be provided on both the top and bottom plates of the housing 110. This allows for selection of normal or reverse installation depending on the installation environment.

[0071] The anti-fall strip 141 extends diagonally along the total heat exchange core assembly 200, with its two ends respectively fixed to the total heat exchange core assembly mounting portion 130 at two opposite corners along its diagonal. In other exemplary structures, the anti-fall strip 141 may extend parallel to the side of the total heat exchange core assembly 200, with its two ends fixed to the base plate of the equipment housing 110. The anti-fall strip 141 may be fixed to the housing or core guide rail at both ends by screws, or one end may be snapped into the housing and the other end may be fixed to the housing or core guide rail by screws.

[0072] Figure 2 This is a bottom view showing the air handling apparatus according to the first embodiment of the present invention, wherein the bottom plate of the air handling apparatus has been removed, exposing its internal structure. Figure 2 As shown, the air handling unit 100 has a housing 110 that forms an internal cavity. The housing 110 is generally rectangular in shape and includes a top plate, a bottom plate, and multiple side plates. The top plate and bottom plate are rectangular, but can also be square. The bottom plate is spaced apart from the top plate and faces it. The side plates connect the periphery of the top plate to the periphery of the bottom plate.

[0073] The air handling unit 100 includes a fresh air inlet 112, an exhaust air outlet 115, a return air outlet 114, and a supply air outlet 113. The fresh air inlet 112 and exhaust air outlet 115 open to the outside, while the supply air outlet 113 and return air outlet 114 open to the inside. They are mounted on a housing 110, more specifically on two oppositely arranged side panels of the housing 110. Specifically, as... Figure 2 As shown, an exhaust vent 115 and a fresh air vent 112 are provided on the side plate on the X1 side, while an air supply vent 113 and a return air vent 114 are provided on the side plate on the X2 side. With this arrangement, a first flow path LL1 from the fresh air vent 112 to the air supply vent 113 and a second flow path LL2 from the return air vent 114 to the exhaust vent 115 are formed inside the housing 110.

[0074] In addition, an exhaust fan 121 and an air supply fan 122 are provided in the housing 110. The exhaust fan 121 and the air supply fan 122 can be centrifugal fans. The exhaust fan 121 is connected to the exhaust port 115, and the air supply fan 122 is connected to the air supply port 113.

[0075] like Figure 3As shown, the air handling unit 100 of this embodiment also includes a total heat exchange core assembly 200 within its housing 110. The total heat exchange core assembly 200 comprises a total heat exchange core body, a fixing member, a filter, etc. The total heat exchange core body is generally block-shaped and includes alternating layers of first and second heat exchange elements (not shown). The total heat exchange core assembly 200 is inclined within the housing 110 and is connected to the first flow path LL1 and the second flow path LL2, respectively. As an example, the total heat exchange core assembly 200 forms a 45° angle with respect to the side plate of the housing. Furthermore, the total heat exchange core assembly 200 may be configured such that, when viewed along the thickness direction of the air handling unit 100, its four sides (faces) are not parallel to the four sides (side plates) of the housing 110. Additionally, the corner formed by the air-facing and exhaust surfaces of the total heat exchange core body is closer to the Y1 side than the corner formed by the return and supply surfaces. In other words, the diagonals in the X1 and X2 directions of the total heat exchange core body are not parallel to the side plates in the X1 and X2 directions of the housing 110.

[0076] An air inlet cavity C2 communicating with a fresh air inlet 112, a return air cavity C4 communicating with a return air inlet 114, an air supply cavity C3 communicating with a supply air outlet 113, and an exhaust cavity C5 communicating with an exhaust outlet 115 are formed between the housing 110 and the total heat exchange core assembly 200.

[0077] In one operating mode of the air handling unit 100, the exhaust fan 121 and the supply fan 122 are turned on. Outdoor air is drawn into the fresh air inlet 112 by the supply fan 122, flows through the total heat exchange core assembly 200, and then enters the room through the supply air outlet 113. Indoor air is drawn into the return air inlet 114 by the exhaust fan 121, flows through the total heat exchange core assembly 200, and then is exhausted to the outside through the exhaust outlet 115. In this way, the outdoor air and the indoor air form a cross-flow in the total heat exchange core assembly 200, and heat and moisture exchange occur between them, thereby reducing the temperature difference between the fresh air and the return air.

[0078] Preferably, a PM2.5 filter 151 is also provided between the total heat exchange core assembly 200 and the air supply fan 122, so as to filter out PM2.5 particles in the air before it enters the room. The PM2.5 filter 151 shown in the figure is roughly L-shaped. In some other cases, the PM2.5 filter 151 may also be straight.

[0079] Preferably, a primary filter 152 is installed at least at one of the sides of the total heat exchange core assembly 200 facing the fresh air inlet 112 and the return air inlet 114. The primary filter 152 is capable of filtering out larger particles of impurities in the air before it enters the total heat exchange core assembly 200, so as to prevent large particles of impurities in the air from damaging the membrane heat exchange elements in the total heat exchange core assembly 200.

[0080] Alternatively, both the PM2.5 filter and the pre-screen filter can be installed at the fresh air inlet 112. Filter types can include activated carbon filters, electrostatic precipitators, etc.

[0081] Sensors 123 may preferably be installed between the fresh air inlet 112 and the total heat exchange core assembly 200, and between the return air inlet 114 and the total heat exchange core assembly 200, for detecting the air quality entering the air handling unit 100. These sensors include, for example, PM2.5 sensors, CO2, TVOC sensors, formaldehyde sensors, odor sensors, temperature sensors, humidity sensors, etc.

[0082] Furthermore, the air handling equipment 100 of this embodiment also includes a first partition unit 300. For example... Figure 2 As shown, the first partition unit 300 is disposed between the air inlet chamber C2 and the air outlet chamber C5. One side of the first partition unit 300 is connected to the side plate of the housing 110, and the other side is connected to a corner of the total heat exchange core assembly 200 via the core mounting guide rail 131 described later. The first partition unit 300 not only separates the air inlet chamber C2 and the air outlet chamber C5, but also serves to fix the total heat exchange core assembly 200. Furthermore, in the height direction, the first partition unit 300 abuts against the top plate and bottom plate of the housing, ensuring the airflow sealing of each airflow path within the housing and ensuring the installation stability of the total heat exchange core assembly 200. The installation structure of the first partition unit 300 is described later.

[0083] like Figure 3As shown, the surface of the first partition unit 300 facing the air inlet cavity C2 is formed as a first guide section 310, which includes a first guide section A, a second guide section B, and a third guide section C. The first guide section A is curved, guiding the air supplied from the fresh air inlet 112 toward the total heat exchange core assembly 200. The first guide section A can be formed by smoothly connecting multiple curves with different curvatures, or by curves with the same curvature. The second guide section B is straight, forming an angle of approximately 90° with the side plate where the fresh air inlet 112 is located. One end of the second guide section B is smoothly connected to the end of the first guide section A, and the other end is connected to the total heat exchange core assembly 200 via the core mounting rail 131. By forming the second guide section B as a straight line, it can easily mate with the core mounting rail 131. The third guide section C is located on the opposite side of the first guide section A and the second guide section B. The third guide section C is formed as a straight line or a curve and is smoothly connected to the starting end of the first guide section A.

[0084] According to this structure, a guide section can be formed using the first partition unit 300, resulting in a simple structure. Furthermore, by setting the shapes of the first, second, and third guide sections, obstruction of the fresh air inlet 112 and the damper assembly 500 can be avoided, reducing airflow resistance. Moreover, the first guide section can direct airflow towards the total heat exchange core assembly 200, effectively improving airflow. This allows for a lower profile in the air handling unit while improving its performance. Even with a small inlet cavity space and a short distance between the damper assembly and the total heat exchange core assembly, the guide structure effectively improves airflow and reduces internal pressure loss.

[0085] In addition, since the first partition unit has a flow guide, it is thicker in shape, which can effectively block the temperature difference between the air inlet and the air outlet, and prevent condensation.

[0086] like Figure 3 As shown, a damper assembly 500 is provided at the fresh air inlet 112. The damper assembly 500 includes a damper plate, a damper sleeve 501, and a motor. The damper plate is rotatably mounted in the damper sleeve 501. The motor is connected to the damper plate and can drive the damper plate to rotate between a closed position and an open position. At least a portion of the damper sleeve 501 is located inside the fresh air inlet 112, and the cross-section of the damper sleeve 501 facing the total heat exchange core assembly 200 is curved.

[0087] In the airflow direction of the first flow path LL1, the starting end of the first guide section A is positioned closer to the fresh air inlet 112 than the edge of the damper sleeve 501 near the total heat exchange core assembly 200. Because the starting end of the first guide section A is positioned closer to the fresh air inlet 112 than the edge of the damper sleeve 501 near the total heat exchange core assembly 200, the air flowing in from the fresh air inlet 112 can be well guided, avoiding noise generation and preventing the formation of vortices between the damper sleeve 501 and the first partition unit 300. Furthermore, as... Figure 5 As shown, an airflow diffusion region S is formed between the first guide section 310 and the side wall of the air valve assembly 500. By providing the airflow diffusion region S, the pressure loss of the airflow can be prevented from increasing, thereby further improving the performance of the air handling equipment.

[0088] Regarding the installation structure of the first partition unit 300, as follows: Figure 5 , Figure 6 As shown, one side of the first partition unit 300 is mounted to the side plate of the housing 110, which is provided with the fresh air inlet 112. A mounting portion 330 is formed on the other side of the first partition unit 300, and the mounting portion 330 protrudes from the other side of the first partition unit 300 and is formed as a convex strip.

[0089] Figure 6 The mounting structure of the first partition unit and the total heat exchange core assembly is shown; for clarity, the illustration of the total heat exchange core assembly is omitted. Figure 6 As shown, a core mounting rail 131 and a filter mounting rail 132 are preferably integrally formed on the total heat exchange core mounting portion 130. A sealing element 133 is inserted into the core mounting rail 131, and the four corners of the total heat exchange core assembly 200 can be embedded into the corresponding core mounting rail 131 of the total heat exchange core mounting portion 130, thereby completing the fixed installation of the total heat exchange core assembly 200. The two sides of the primary filter 152 can be inserted into the corresponding filter mounting rail 132 of the total heat exchange core mounting portion 130, thereby completing the installation of the primary filter 152. Alternatively, the filter mounting rail 132 can be configured to simultaneously accommodate a PM2.5 filter and a primary filter, facilitating the simultaneous fixing of multiple filters.

[0090] like Figure 5 , Figure 6 As shown, the mounting portion 330 of the first partition unit 300 is fixed to the side of the core mounting guide rail 131 opposite to the total heat exchange core assembly 200. Furthermore, the mounting portion 330 of the first partition unit 300 is also connected to the filter mounting guide rail 132 on both sides. Preferably, after the first partition unit 300 is connected to at least one of the core mounting guide rail 131 and the filter mounting guide rail 132, they are secured with screws to achieve a stable connection.

[0091] like Figure 4 As shown, the surface of the first partition unit 300 facing the exhaust cavity C5 is formed as a second flow guide 320, which includes a straight flow guide 321 parallel to the windward surface 210 of the total heat exchange core assembly 200. By setting the straight flow guide 321 parallel to the windward surface 210 of the total heat exchange core assembly 200, the air discharged from the total heat exchange core assembly 200 can be better guided to the exhaust fan 121, avoiding an increase in air pressure loss and further improving the efficiency of the air handling equipment. Alternatively, the second flow guide 320 can also be curved.

[0092] (Second Implementation)

[0093] Figure 7 This is a partial perspective view of the second partition unit of the air handling device according to the second embodiment of the present invention.

[0094] The main difference between the air handling apparatus of the second embodiment and the air handling apparatus of the first embodiment is that it further includes a second partition unit 400. The structure of the second partition unit will be described below. For structures identical to those in the first embodiment, the same symbols as in the first embodiment will sometimes be used, and detailed descriptions will be omitted.

[0095] like Figure 7 As shown, the second partition unit 400 is disposed between the exhaust cavity C5 and the supply cavity C3. One side of the second partition unit 400 is connected to the side plate of the housing, and the other side serves as a mounting part and is connected to a corner of the total heat exchange core assembly 200 via a core mounting guide rail.

[0096] like Figure 7 As shown, the surface of the second partition unit 400 facing the air supply cavity C3 is formed as a third guide section 410, and the surface of the second partition unit 400 facing the air exhaust cavity C5 is formed as a fourth guide section 420. The third guide section 410 is configured to guide the air discharged from the total heat exchange core assembly 200 toward the air supply port 113.

[0097] like Figure 8As shown, the third guide section 410 includes a first guide section A1 near the side of the total heat exchange core assembly 200, a third guide section C1 near the air outlet 113, and a second guide section B1 located between the first guide section A1 and the third guide section C1. The first guide section A1 and the second guide section B1 are smoothly connected. One end of the third guide section C1 is smoothly connected to the second guide section B1, and the other end is connected to the side plate of the housing 110. The first guide section A1 is formed as a straight line, extending parallel to the exhaust surface of the total heat exchange core assembly 200. Alternatively, the first guide section A1 can also be formed as a curve. The second guide section B1 is formed by smoothly connecting multiple curves with different curvatures. The curvature of the first guide section A1 is greater than the curvature of the second guide section B1.

[0098] As described above, an air supply fan 122 is provided between the air outlet 113 and the total heat exchange core assembly 200, and the curvature of the second guide section B1 can be set to be the same as the curvature of the volute of the air supply fan 122.

[0099] Furthermore, the surface of the second partition unit 400 facing the exhaust cavity C5 is formed as a fourth guide section 420, which is configured to guide the air discharged from the total heat exchange core assembly 200 toward the exhaust port 115. An exhaust fan 121 is provided between the exhaust port 115 and the total heat exchange core assembly 200, and the curvature of at least a portion of the guide section of the fourth guide section 420 is the same as the curvature of the volute of the exhaust fan 121.

[0100] According to the structure of the air handling equipment of this second embodiment, the third and fourth airflow guides can be formed using the second partition unit 400, resulting in a simple structure. Furthermore, the third and fourth airflow guides can be used to guide the airflow respectively, effectively improving the airflow and further enhancing the performance of the air handling equipment.

[0101] (Third Implementation)

[0102] Figure 9 This is a partial perspective view of the air handling device according to the third embodiment of the present invention. Figure 10 This is a bottom view showing the air handling device according to the third embodiment of the present invention.

[0103] The main difference between the air handling device of the third embodiment of the present invention and the air handling device of the second embodiment is that a filter 151 is provided between the air outlet 113 and the total heat exchange core assembly 200.

[0104] In the third embodiment of the present invention, the surface of the second partition unit 400 facing the air supply cavity C3 is formed as a third flow guide 410, which is provided to extend from the end of the total heat exchange core assembly 200 toward the filter screen 151.

[0105] According to the structure of the air handling device of the third embodiment, it can be applied to an air handling device with a filter, and the airflow can be guided to the filter by the third guide section 410, which can avoid the increase of pressure loss and effectively improve the airflow.

[0106] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any variations and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the invention, fall within the protection scope defined by the claims of the present invention.

[0107] For example, the first partition unit can also be independently installed within the housing, perpendicular to the bottom and top plates. Alternatively, an inner housing can be installed within the main housing, which can be made of flexible materials such as foam. The first partition unit can be integrally molded from the foam material and the inner housing, and the second partition unit, etc., can also be integrally molded with the inner housing. This results in a simple structure, convenient processing, and strong sealing of the airflow path. Furthermore, by installing the inner housing, it also provides functions such as heat insulation, sound absorption, and anti-condensation.

[0108] Furthermore, the connection method between the first segmentation unit and the second segmentation unit and the heat exchange core assembly is not limited to the above; it can also be any connection method such as snap-fit ​​or riveting.
