One side of the Y direction is designated as Y1, and the other side as Y2. One side of the Z direction is designated as Z1, and the other side as Z2.

[0091] (Overall structure of air handling equipment)

[0092] like Figure 1 As shown, the air handling device 1 includes: a housing 10 having an air inlet JF and an air outlet CF, and an airflow passage TL forming inside the housing that connects the air inlet JF and the air outlet CF; a heat exchange element 20 disposed on the airflow passage TL; and a sensor assembly 30 disposed between the air inlet JF and the heat exchange element 20.

[0093] Here, as Figure 1As shown, a damper assembly 40 is provided at the air inlet JF, which controls the introduction of airflow into the housing 10. Furthermore, a fan 50 and a filter 60 are also provided inside the housing 10. The fan 50 generates airflow from the air inlet JF towards the air outlet CF, and the filter 60 filters the airflow passing through the airflow passage TL.

[0094] In addition, although not shown, the air handling unit 1 also includes a control unit that controls the operation of the air handling unit 1.

[0095] (Structure of the shell)

[0096] like Figure 1 As shown, the shell 10 is generally rectangular and has a top plate 11, a bottom plate (not shown) that is spaced apart from the top plate 11 and opposite to it, and a side plate 12 that extends from the periphery of the top plate 11 to the periphery of the bottom plate (the top plate 11 and the bottom plate can be formed separately from the side plate 12, or they can be formed integrally with the side plate 12).

[0097] Here, as Figure 1 As shown, an air inlet JF and an air outlet CF are provided on the side plate 12 of the housing 10. Specifically, the side plate 12 has: a first side plate 121 and a second side plate 122 spaced apart and opposite each other in the X direction; and a third side plate 123 and a fourth side plate 124 spaced apart and opposite each other in the Y direction. A fresh air inlet XF constituting the air inlet JF (for introducing fresh air from the outside) and an exhaust air outlet PF constituting the air outlet CF are formed on the first side plate 121. A return air inlet HF constituting the air inlet JF (for drawing air from the room) and a supply air outlet SF constituting the air outlet CF (for supplying air to the room) are formed on the second side plate 122. The second side plate 122 is located on the X2 direction side of the first side plate 121. The fourth side plate 124 is located on the Y2 direction side of the third side plate 123. Furthermore, the fresh air inlet XF is located on the Y2 direction side of the exhaust air outlet PF, and the return air outlet HF is located on the Y2 direction side of the supply air outlet SF. Furthermore, the airflow path TL includes: the supply air path TL1 from the fresh air inlet XF to the supply air outlet SF; and the exhaust air path TL2 from the return air outlet HF to the exhaust air outlet PF.

[0098] In addition, such as Figure 1As shown, a partition 13 is also provided inside the housing 10. The partition 13 cooperates with the heat exchange element 20 to separate a fresh air cavity Q1, an air outlet cavity Q2, a return air cavity Q3, and an exhaust air cavity Q4 within the housing 10. The fresh air cavity Q1 constitutes the portion of the air supply path TL1 located upstream of the heat exchange element 20, the air outlet cavity Q2 constitutes the portion of the air supply path TL1 located downstream of the heat exchange element 20, the return air cavity Q3 constitutes the portion of the exhaust air path TL2 located upstream of the heat exchange element 20, and the exhaust air cavity Q4 constitutes the portion of the exhaust air path TL2 located downstream of the heat exchange element 20. The partition 13 includes: a first partition 131 separating the fresh air cavity Q1 from the exhaust air cavity Q4; a second partition 132 separating the air outlet cavity Q2 from the return air cavity Q3; and a third partition 133 separating the air outlet cavity Q2 from the exhaust air cavity Q4.

[0099] In addition, although not shown, at least one of the bottom plate and top plate 11 of the housing 10 is provided with a maintenance opening for the heat exchange element 20 to enter and exit, and a maintenance cover plate for opening and closing the maintenance opening.

[0100] (Structure of heat exchange elements)

[0101] like Figure 1 As shown, the heat exchange element 20 has: a first airflow channel forming part of the air supply path TL1; and a second airflow channel forming part of the exhaust path TL2, and the airflow flowing through the first airflow channel can exchange heat with the airflow flowing through the second airflow channel.

[0102] Here, as Figure 1 As shown, the heat exchange element 20 is generally rectangular, with its top and bottom surfaces perpendicular to the Z-direction, and its four sides inclined relative to the X and Y directions, respectively. When viewed along the Z-direction, one corner of the heat exchange element 20 (in the illustrated example, the corner on the Y2 direction side) abuts against a guide rail (extending along the Z-direction in the illustrated example) located on the fourth side plate 124, while the other three corners abut against guide rails (extending along the Z-direction in the illustrated example) located on the partition plates 13 (specifically, at the ends of the first partition plate 131, the second partition plate 132, and the third partition plate 133 near the center of the housing 10). Furthermore, the heat exchange element 20 is fixed within the housing 10 via the guide rails.

[0103] In addition, a top plate and a bottom plate connected by side columns can be provided on the upper and lower sides of the heat exchange element 20 to form a full heat exchange core assembly.

[0104] (Structure of the sensor assembly)

[0105] like Figures 2 to 6As shown, the sensor assembly 30 includes a first sensor 312, which is used to detect particulate matter (i.e., the first sensor 312 is a particulate matter sensor, such as a PM2.5 sensor). It is positioned on the airflow passage TL and avoids the projection area TY (i.e., the area projected along the centerline of the air inlet JF, which in the illustrated example is a column extending along the X direction) of the air inlet JF (in the illustrated example, the centerline of the air inlet JF extends along the X direction). Furthermore, the sensor assembly 30 includes a first sensor housing 311 covering the first sensor 312. The first sensor housing 311 has an airflow inlet RK, which is located on the side of the first sensor housing 311 away from the projection area TY.

[0106] Here, as Figure 1 and Figure 2 As shown, the first sensor 312 is disposed on the air supply path TL1, and located between the fresh air inlet XF and the heat exchange element 20 (that is, the sensor assembly 30 is disposed within the fresh air cavity Q1). Specifically, the sensor assembly 30 is disposed on the Y2 direction side of the projection area TY of the air inlet JF, close to the fourth side plate 124, and extends along the X direction. Furthermore, as... Figures 2 to 4 As shown, the first sensor housing 311 also has an airflow outlet CK, which is located on the side of the first sensor housing 311 away from the projection area TY (in the illustrated example, this is the Y2 direction side, and it is closer to the X2 direction side than the airflow inlet RK). Furthermore, as... Figure 5 and Figure 6 As shown, the first sensor housing 311 is generally rectangular in shape, having a housing body 3111 in the shape of an open box and a cover plate 3112 covering the opening of the housing body 3111. A partition (extending along the Z direction in the illustrated example) is provided inside the first sensor housing 311 (specifically the housing body 3111) to separate airflow paths. Airflow inlets RK and CK are respectively provided on the top and bottom walls of the housing body 3111, located on either side of the partition, corresponding to the air inlets and outlets on the first sensor 312. By providing airflow inlets RK and airflow outlets CK on both the top and bottom walls of the housing body 3111, particulate matter is less likely to accumulate inside the first sensor housing 311. The cover plate 3112 is fixed to the housing body 3111 by snap-fitting. Furthermore, a small fan (not shown) may be provided inside the first sensor housing 311. The small fan is used to introduce external gas into the first sensor housing 311 through the airflow inlet RK, so that it flows through the first sensor 312 and is blown out from the airflow outlet CK.

[0107] In addition, such as Figures 2 to 6As shown, the sensor assembly 30 further includes a second sensor 322, which is used to detect at least one of temperature and humidity (i.e., the second sensor 322 is a temperature sensor, a humidity sensor, or a temperature and humidity sensor), and is disposed on the airflow passage TL, downstream of the first sensor 312. Furthermore, as... Figure 4 As shown, the second sensor 322 is below the bottom edge of the fresh air inlet XF.

[0108] In addition, such as Figures 2 to 6 As shown, the sensor assembly 30 includes a second sensor housing 321 covering the second sensor 322. The second sensor housing 321 is generally cuboid in shape and has a plurality of slits.

[0109] In addition, such as Figure 4 and Figure 5 As shown, the second sensor 322 is entirely within the height range of the first sensor 312. Specifically, the second sensor housing 321 is entirely within the height range of the first sensor housing 311 (in the illustrated example, the Z2 direction end of the second sensor housing 321 is closer to the Z1 direction end than the Z2 direction end of the first sensor housing 311, and the Z1 direction end of the second sensor housing 321 is approximately flush with the Z1 direction end of the first sensor housing 311). Furthermore, when the minimum distance from the second sensor 322 to the heat exchange element 20 is L1, the following relationship is preferably satisfied: L1 ≥ 10 mm.

[0110] In addition, such as Figures 2 to 6 As shown, the sensor assembly 30 includes a base 39 on which a plurality of sensor fixing parts are provided. The plurality of sensor fixing parts include: a first sensor fixing part for detachably fixing at least one of a first sensor housing 311 and a first sensor 312; and a second sensor fixing part for detachably fixing at least one of a second sensor housing 321 and a second sensor 322. Furthermore, the base 39 is elongated in the X direction, and the plurality of sensor fixing parts are arranged at intervals along the length of the base 39. The base 39 is fixed to the top plate 11 of the housing 10 (but is not limited thereto; it may also be fixed to the side plate 12, or simultaneously fixed to both the top plate 11 and the side plate 12).

[0111] (Structure of the damper assembly)

[0112] like Figures 2 to 4 As shown, the damper assembly 40 includes a damper 41 and a motor (not shown) that drives the damper 41.

[0113] Here, as Figure 3 and Figure 4As shown, the damper 41 includes a cylinder portion 411 and a valve plate 412 that is rotatably disposed (in the illustrated example, rotatable about an axis extending in the Y direction, but not limited thereto, and can be configured to be rotatable about an axis inclined with respect to the Y direction) within the cylinder portion 411. The cylinder portion 411 extends in the X direction and has a shape and size that substantially match the fresh air inlet XF.

[0114] Further, as shown in Figure 3 and Figure 4 As shown, the damper assembly 40 has a motor housing portion 42 in which a motor is housed. Specifically, the motor housing portion 42 includes a motor seat 421 and a motor cover 422 that together enclose a space in which the motor is housed. The motor seat 421 is formed integrally with the cylinder portion 411 (in the illustrated example, formed at the end portion on the Y2 direction side of the cylinder portion 411), and the motor cover 422 is detachably attached to the motor seat 421 (in the illustrated example, covers the motor from the Y2 direction side).

[0115] Further, as shown in Figures 2 to 4 The motor of the damper assembly 40 is located on the upstream side of the sensor assembly 30 (that is, the sensor assembly 30 is located on the downstream side of the motor of the damper assembly 40), and is located on the same side (in the illustrated example, the Y2 direction side) of the projection area TY as the sensor assembly 30. Also, the motor housing portion 42 is higher than the sensor assembly 30 (that is, the sensor assembly 30 is lower than the motor housing portion 42).

[0116] (Main effects of the present embodiment)

[0117] According to the air processing device 1 of the present embodiment, the sensor assembly 30 includes a first sensor 312 for detecting particulate matter, which is disposed on the airflow passage TL and avoids the projection area TY of the fresh air inlet JF, and includes a first sensor cover 311 that covers the first sensor 312, the first sensor cover 311 being provided with an airflow inlet RK disposed on the side of the first sensor cover 311 away from the projection area TY, so that the main airflow drawn into the housing 10 from the fresh air inlet JF is prevented from strongly impacting the first sensor cover 311 to cause particulate matter in the main airflow to be unable to enter the airflow inlet RK of the first sensor cover 311, and the airflow flow rate flowing into the airflow inlet RK of the first sensor cover 311 is suppressed from fluctuating greatly, thereby ensuring the detection accuracy of the first sensor 312 within the first sensor cover 311, and on the other hand, the first sensor cover 311 is also suppressed from impeding the main airflow from flowing toward the heat exchange element 20 to cause the heat exchange efficiency of the heat exchange element 20 to decrease.

[0129] Further, in the above-described embodiment, a temperature sensor (e.g., a temperature sensing element) can also be provided in the air outlet cavity Q2 near the air outlet face of the heat exchange element 20, and the temperature sensing element can be used to detect the temperature of the airflow after heat exchange by the heat exchange element 20. Thus, it can be determined whether there is a risk of condensation inside the air handling device. Further, the detection results of the sensor assembly on the fresh air inlet XF side, the plurality of sensors on the return air inlet HF side, and the temperature sensor in the air outlet cavity Q2 can be used separately to adjust the operating state of the heat exchange element 20, or can be used in combination, partially or entirely, to adjust the operating state of the heat exchange element 20. Further, the detection accuracy of each sensor can be corrected by a correction value.

[0130] Further, in the above-described embodiment, a filter screen can also be provided on at least one of the upstream side and the downstream side of the heat exchanger element 20 on the airflow passage TL.

[0131] It should be understood that, within the scope of the present application, each part of the embodiments can be freely combined, or each part of the embodiments can be appropriately modified or omitted.
