[Embodiment]
[Air handling unit configuration]
The configuration of an air handling unit 1 according to an embodiment of the present disclosure will be described with reference to FIGS. 1 to 5. The air handling unit 1 includes a casing 2, a filter 3, an adjustment section 4, a fan 7, a first partition plate 23, a second partition plate 24, and an imaging section 90.

FIG. 1 is a perspective view schematically showing the appearance of the air handling unit 1. As shown in FIG.
The casing 2 has a plurality of outer wall panels 2a to 2f assembled into a box shape. The front surface (vertical surface on the near side in FIG. 1) is made up of three front panels 2a, and the back surface (the vertical surface on the back side in FIG. 2) is made up of three back panels 2b. Further, the left side surface (vertical surface on the left side in FIG. 1) is constituted by one left surface panel 2c, and the right side surface (vertical surface on the right side in FIG. 2) is constituted by one right surface panel 2d. Furthermore, the upper surface is constituted by one upper surface panel 2e, and the lower surface is constituted by one base 2f. These panel configurations are examples, and implementation of the present disclosure is not limited thereto.

An air inlet 21 and an air outlet 22 are formed in the upper panel 2e. The inlet 21 is provided on the right panel 2d side of the upper panel 2e, and a duct (not shown) that communicates with the outdoors or indoors is connected to the inlet 21. The outlet 22 is provided on the left panel 2c side of the upper panel 2e, and a duct (not shown) that communicates with the interior of the room is connected to the outlet 22. As a result, outside air or indoor air flows into the casing 2 via the duct and the inlet 21, and after the temperature and humidity are adjusted, it is supplied indoors via the outlet 22 and the duct.

FIG. 2 is a perspective view showing the internal structure of the air handling unit 1. FIG. 2 is a perspective view taken at the same angle as FIG. 1, and the illustration of the front panel 2a is omitted.
FIG. 3 is a perspective view of the internal structure of the air handling unit 1 viewed from the right panel 2d side. In FIG. 3, the description of the casing 2 other than the base 2f is omitted.
FIG. 4 is a sectional view of the air handling unit 1. FIG. 4 shows a cross section midway between the front panel 2a and the back panel 2b.
FIG. 5 is a top plan view showing the internal structure of the air handling unit 1. As shown in FIG. In FIG. 5, illustrations of the top panel 2e, front panel 2a, and left panel 2c are omitted.

See FIG. 2. Inside the casing 2, a filter 3, a first partition plate 23, an adjustment section 4, a second partition plate 24, a fan 7, a drain pan 60, a drainage channel 61, and an imaging section 90 (FIG. 4) are provided. The filter 3, the first partition plate 23, the adjustment part 4, the second partition plate 24, and the fan 7 are installed in this order from the right panel 2d on the inlet 21 side toward the left panel 2c on the outlet 22 side. .

The fan 7 is, for example, a plug fan. The fan 7 is located directly below the outlet 22 and is fixed to the pedestal 12. The pedestal 12 is fixed to the base 2f via a vibration absorbing mechanism 14 such as laminated rubber or a spring that absorbs vibrations. The fan 7 takes in air from a passage port 24a, which will be described later, and blows it upward, thereby forming an airflow from the inflow port 21 toward the outflow port 22.

The adjustment section 4 is provided within the casing 2 on the upstream side of the fan 7 in the airflow direction. The adjustment unit 4 includes a cold water coil 41, a hot water coil 42, and a humidifier 43. The cold water coil 41, the hot water coil 42, and the humidifier 43 are installed in this order from the right panel 2d toward the left panel 2c.

The cold water coil 41 and the hot water coil 42 are each water-cooled heat exchangers. Chilled water is supplied to the cold water coil 41 from a heat source device outside the machine, and the air is cooled by the cold water. Hot water is supplied to the hot water coil 42 from a heat source device outside the machine, and the air is heated by the hot water. The humidifier 43 adjusts humidity by mixing water vapor or water droplets (mist) with air. Thereby, the adjustment unit 4 adjusts the temperature and humidity of the air.

Note that the adjustment unit 4 only needs to have at least one of the cold water coil 41, the hot water coil 42, and the humidifier 43, and may have a configuration that adjusts at least one of the temperature and humidity of the air.

The filter 3 is provided within the casing 2 on the upstream side of the adjustment section 4 in the airflow direction. Filter 3 has a pre-filter and a main filter. The filter 3 purifies the air by removing dust from the air in two stages.

The first partition plate 23 is provided between the filter 3 and the adjustment section 4. The first partition plate 23 is a plate-like member that extends vertically or diagonally from the base 2f to the top panel 2e, and is made of a metal plate such as steel. The first partition plate 23 partitions the internal space of the casing 2 into an inflow side space S1 in which the inflow port 21 is provided and an adjustment chamber S2 in which the adjustment section 4 is provided. The first partition plate 23 is formed with a passage port 23a (FIG. 4) through which air passes. The passage port 23a is sandwiched between the filter 3 and the adjustment section 4.

The second partition plate 24 is provided between the adjustment section 4 and the fan 7. The second partition plate 24 is a plate-like member that extends vertically or diagonally from the base 2f to the top panel 2e, and is made of a metal plate such as steel. The second partition plate 24 partitions the internal space of the casing 2 into an adjustment chamber S2 and a fan chamber S3 in which the fan 7 is provided. A passage port 24a (FIG. 3) through which air from the adjustment chamber S2 passes to the fan chamber S3 is formed in the second partition plate 24 at a position corresponding to the fan 7. The passage port 24a is covered with a net-like fan guard 24b (FIG. 3).

The adjustment chamber S2 is a substantially rectangular parallelepiped-shaped space formed by the first partition plate 23, the second partition plate 24, the front panel 2a, the back panel 2b, the upper panel 2e, and the base 2f. The distance between the first partition plate 23 and the second partition plate 24 (the width of the adjustment chamber S2) is, for example, 700 mm. The distance between the front panel 2a and the back panel 2b (the depth of the adjustment chamber S2) is, for example, 600 to 1000 mm. The distance between the top panel 2e and the base 2f (the height of the adjustment chamber S2) is, for example, 1600 mm to 2050 mm, which is longer than the width and depth of the adjustment chamber S2. Therefore, the adjustment chamber S2 becomes a space that is long in the vertical direction.

See FIG. 4. The drain pan 60 is a tray that receives condensed water generated in and around the adjustment section 4 (for example, the cold water coil 41). The drain pan 60 is installed on the base 2f of the adjustment chamber S2. The drain pan 60 is inclined downward along the direction from the first partition plate 23 to the second partition plate 24 (airflow direction).

The drain channel 61 is a pipe for discharging condensed water received by the drain pan 60 from the drain pan 60 to the outside of the casing 2 . The drainage channel 61 is provided below the pedestal 12. A drain hole 61 a that opens into the drain pan 60 is formed at one end of the drain channel 61 . The other end 61b of the drainage channel 61 projects to the outside of the casing 2 below the left panel 2c. The end portion 61b is connected to a pipe (not shown). The drainage channel 61 may have a structure other than piping, as long as it has a function of discharging the condensed water received by the drain pan 60, and may be a drain groove, for example.

The imaging unit 90 is provided in the adjustment chamber S2 and images the inside of the adjustment chamber S2. More specifically, as shown in FIGS. 4 and 5, the imaging unit 90 has a mounting bracket near the corner where the second partition plate 24 and the back panel 2b connect, in the vicinity of the top panel 2e. (not shown). The imaging direction D1 of the imaging unit 90 is a direction in which both the adjustment unit 4 and the drain pan 60 are viewed from above. Therefore, the adjustment section 4 and the drain pan 60 are included in the image acquired by the imaging section 90.

Further, the imaging section 90 is provided closer to the second partition plate 24 than the adjustment section 4, and the imaging direction D1 faces the first partition plate 23 side. Therefore, it is possible to image the adjustment section 4 while maintaining a distance from the adjustment section 4 in the width direction (the direction in which the first partition plate 23 and the second partition plate 24 face each other), and a wider range of the adjustment section 4 can be captured. It can be captured in images.

[Functional configuration of imaging section]
FIG. 6 is a block diagram showing the functional configuration of the management system 100 of the present disclosure.
The management system 100 includes a plurality of air handling units 1 and a management device 80. The management device 80 is installed, for example, in a building (for example, a management center) different from the building (for example, a factory, a building, etc.) in which each of the plurality of air handling units 1 is installed. The management device 80 is a device for remotely inspecting the plurality of air handling units 1, and is, for example, a general-purpose computer device including a processor and memory. The functions of the management device 80 are realized by causing the general-purpose computer device to execute a predetermined program. The management device 80 includes a management control section 81, an input section 82 such as a keyboard, a display section 83 such as a display, and a communication section 84.

The imaging section 90 includes an imaging element 91, a light source 92, an imaging control section 93, and a communication section 94. The image sensor 91 is, for example, a CCD image sensor. The light source 92 is, for example, a white LED. The imaging control section 93 is a microcomputer including a processor and a memory, and controls the imaging device 91, the light source 92, and the communication section 84. For example, when the imaging device 91 performs imaging, the imaging control unit 93 illuminates the inside of the adjustment chamber S2 by causing the light source 92 to emit light. The communication unit 94 is communicably connected to the communication unit 84 of the management device 80 via the network N1. The image acquired by the image sensor 91 is temporarily stored in the image capture control section 93, and is transmitted from the communication section 84 to the management device 80 via the network N1. The management device 80 collects images acquired by each of the plurality of air handling units 1.

[Operation of air handling unit]
The cold water cooled by the heat source device outside the machine is passed through the cold water coil 41, and the hot water heated by the heat source machine outside the machine is passed through the hot water coil 42, and the fan 7 is rotated. As a result, the air in the adjustment chamber S2 is sucked into the fan chamber S3, and the adjustment chamber S2 and the inflow side space S1 are brought into a negative pressure state where the pressure is lower than that outside the casing 2. Therefore, external air flows into the inflow side space S1 from the inflow port 21.

After the air that has flowed into the inflow side space S1 has dust removed by the filter 3, it flows into the cold water coil 41 and the hot water coil 42 from the passage port 23a of the first partition plate 23. The temperature of the inflowing air is adjusted by exchanging heat with the cold water/hot water flowing through each coil 41, 42. The humidity of the temperature-adjusted air is adjusted by a humidifier 43.

When the humidity-adjusted air flows into the fan room S3 from the passage port 24a, it is supplied into the room from the outflow port 22 via a duct (not shown). Therefore, the fan chamber S3 is in a positive pressure state where the pressure is higher than that of the adjustment chamber S2, the inflow side space S1, and the outside of the casing 2.

[Air handling unit inspection operation]
In the air handling unit 1, for example, during cooling operation, when air is cooled to a dew point temperature or lower by the chilled water coil 41, moisture in the air is condensed. This condensed water is received by a drain pan 60 and discharged to the outside of the casing 2 through a drainage channel 61. In this way, since condensed water adheres to the adjustment section 4 and the drain pan 60, they may become dirty due to the generation and propagation of bacteria and mold. The dirt on the adjustment section 4 and the drain pan 60 worsens with the passage of time, and there is a risk that the air inside the casing 2 will eventually be contaminated and a musty odor will be generated, or that the drain channel 61 will be clogged.

Conventionally, an operator visually inspects the adjustment section 4 and drain pan 60, for example, every month, and if dirt is found on the adjustment section 4 and drain pan 60 during the inspection, the operator removes the dirt. Therefore, even if the adjustment section 4 and the drain pan 60 are not dirty, it is necessary for the operator to periodically go to the installation site of the air handling unit 1.

In contrast, the air handling unit 1 of the present embodiment acquires images by capturing images of the adjustment section 4 and the drain pan 60 using the imaging section 90 every week, for example. The image is then transmitted to the management device 80 via the communication unit 94. Note that the imaging by the imaging unit 90 may be performed periodically as described above, or the management control unit 81 may perform the imaging by the operator by inputting an instruction for imaging into the input unit 82 of the management device 80. The process may be executed by issuing an imaging instruction to the imaging unit 90 from here.

The management control unit 81 makes an abnormality determination based on the image sent to the management device 80. For example, the normal image and the transmitted image are compared, and if the difference is greater than or equal to a predetermined value, it is determined that there is an abnormality in the adjustment section 4 and the drain pan 60, and an alert is displayed on the display section 83. Abnormality determination performed by the management device 80 may use various methods and is not limited to the above method. Furthermore, it is not essential for the management device 80 to make an abnormality determination.

For example, the management device 80 may display the image as it is on the display unit 83 without determining the abnormality, and the operator may determine whether the adjustment unit 4 and the drain pan 60 are abnormal based on the image. Alternatively, an edge device (for example, a general-purpose computer device) may be provided on the imaging unit 90 side, and after the imaging unit 90 executes abnormality determination of the captured image, the abnormality determination result may be transmitted to the management device 80.

As described above, according to the air handling unit 1 of the present embodiment, the imaging unit 90 acquires an image including the adjustment unit 4 and the drain pan 60, and transmits the image to the management device 80 located remotely from the air handling unit 1. and can be displayed. Therefore, the operator can check the conditions of the adjustment section 4 and the drain pan 60 without going to the installation site of the air handling unit 1. Since the operator only needs to go to the installation site when an abnormality such as dirt on the adjustment section 4 and the drain pan 60 is confirmed, the burden of maintenance and inspection work on the air handling unit 1 can be reduced.

[Modified example]
The present disclosure is not limited to the embodiments described above, and various changes are possible. In the following modified examples, the same components as those in the above embodiment are given the same reference numerals, and the description thereof will be omitted as appropriate.

[Modification 1 of the installation position of the imaging unit]
FIG. 7 is a sectional view of an air handling unit according to a modification of the embodiment. The imaging units 90a and 90b according to the modified example are different from the imaging unit 90 according to the above-described embodiment in the installation position, but have other points in common. Note that both the imaging units 90a and 90b may be provided, or only one of them may be provided.

The imaging section 90a is installed above the upper end 4a of the adjustment section 4 and near the first partition plate 23. The imaging direction D1a of the imaging unit 90a is a direction in which the drain pan 60 and the drain hole 61a of the drain channel 61 are viewed from above. Therefore, the drain pan 60 and the drain hole 61a are visible in the image acquired by the imaging unit 90a. Further, the adjustment section 4 is not shown in the image.

If the drain channel 61 is clogged, condensed water accumulates in the drain pan 60, resulting in stagnation of drainage. In this modification, by including the drainage hole 61a in the imaging direction D1a of the imaging unit 90a, clogging of the drainage channel 61 can be confirmed more reliably. Note that the imaging unit 90a may image the drain hole 61a as described above, or may image the vicinity of the drain hole 61a without capturing the image of the drain hole 61a. The vicinity of the drain hole 61a is, for example, a region of the drain pan 60 on the drain hole 61a side.

The imaging unit 90b is installed above the upper end of the passage port 24a of the second partition plate 24 and near the upper end of the passage port 24a. The upper end of the passage port 24a is located below the upper end 4a of the adjustment section 4, and the position of the imaging section 90b is located below the upper end 4a of the adjustment section 4. The imaging direction D1b of the imaging section 90b is a direction in which the adjustment section 4 and the drain pan 60 are viewed from above. Note that the imaging section 90b may overlook only the adjustment section 4 and may not include the drain pan 60 in its angle of view.

The imaging section 90b is located below the imaging section 90 and the imaging section 90a in the adjustment chamber S2, and therefore is close to the lower part of the adjustment section 4 and the drain pan 60. Since the condensed water drips downward through the adjustment section 4 (for example, the cold water coil 41), the lower portion of the adjustment section 4 tends to be more likely to become dirty. The imaging unit 90b can check the states of the adjustment unit 4 and the drain pan 60 in more detail by capturing images of easily dirty parts nearby.

On the other hand, if the imaging section 90b is installed below the passage port 24a, the airflow passing through the passage port 24a may be obstructed, and the imaging section 90b itself may also vibrate due to the airflow. Therefore, in order not to obstruct the airflow and to prevent the imaging section 90b from vibrating due to the airflow, the imaging section 90b is installed above the passage port 24a.

[Modification example 2 of the installation position of the imaging unit]
FIG. 8 is a sectional view of an air handling unit according to a modification of the embodiment. The imaging unit 90b according to the modification has the same configuration as the imaging unit 90b in FIG. 7. The air handling unit according to this modification further includes a mirror 95.

The mirror 95 is located in the imaging direction D1b of the imaging section 90b, and its position and angle are set so that the drain hole 61a of the drainage channel 61 is reflected when viewed from the imaging section 90b. The imaging unit 90b has a problem in that while it can confirm the adjustment unit 4 and the drain pan 60 in more detail, it cannot capture the drain hole 61a of the drain channel 61. In this modification, by further providing a mirror 95, the drainage hole 61a can be captured in the image acquired by the imaging unit 90b via the mirror 95. Thereby, it is possible to check the adjustment part 4 and the drain pan 60 in more detail, and to check whether the drain channel 61 is clogged more reliably.

[Modified example of drainage hole]
FIG. 9 is a sectional view of an air handling unit according to a modification of the embodiment. In this modification, the method of draining water from the drain pan to the drainage channel is different from the above embodiment. The drain pan 62 according to the modified example is installed below the adjustment chamber S2. A recess 62a is formed in the drain pan 62.

The drainage channel according to the modified example is a pipe that guides water L1 that is forcibly discharged from the drain pan 62 by the drain pump 64. Hereinafter, the drainage channel on the drain pan 62 side (upstream side) of the drain pump 64 will be referred to as the "drainage channel 63", and the drainage channel on the opposite side (downstream side) will be referred to as the "drainage channel 65". A drainage hole 63a into which water L1 flows is formed at the lower end of the drainage channel 63. The drain hole 63a opens toward the bottom of the recess 62a. The drainage channel 65 penetrates the front panel 2a in the thickness direction and projects to the outside of the casing 2.

When the drain pump 64 operates, water L1 accumulated in the drain pan 62 is sucked through the drain hole 63a of the drain channel 63. The sucked water is sent to the drainage channel 65 via the drain pump 64, and is discharged to the outside of the casing 2 through the drainage channel 65.

The imaging unit 90c according to the modification images both the adjustment unit 4 and the drain pan 62. The imaging unit 90c images the concave portion 62a of the drain pan 62 so as to include it in the imaging direction D1c. Here, the drainage hole 63a opens toward the recess 62a as shown in FIG. 9, and therefore is not captured in the image captured by the imaging unit 90c. On the other hand, the image captured by the imaging unit 90c shows the vicinity of the drain hole 63a, such as the recess 62a and the side surface of the drain channel 63.

When the drainage channels 63 and 65 are clogged (or about to be clogged), dirt near the drain hole 63a becomes noticeable, and a large amount of water L1 accumulates near the drain hole 63a. Therefore, clogging of the drain channels 63 and 65 can be indirectly confirmed by capturing an image of the vicinity of the drain hole 63a using the imaging unit 90c.

[Other variations]
Note that at least some of the embodiments and modifications described above may be arbitrarily combined with each other.
