Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a ducted air conditioner and air conditioning system. Background Technology

[0002] Ductless air conditioning units are divided into low static pressure ductless units and medium-high static pressure ductless units. Current residential and commercial central air conditioning systems use multi-split configurations, requiring a low static pressure ductless unit for each room. This results in low ceiling height, short air delivery distance, and high cost. While medium-high static pressure ductless units can deliver air over longer distances and, through branch ducts and valves, can supply air to the entire house from a single unit, their large installation size and complex, expensive room-by-room air delivery solutions limit their widespread use in this scenario.

[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0004] In response to the problems pointed out in the background art, this utility model proposes a ducted air conditioner and air conditioning system, which realizes the application of medium and high static pressure ducted air conditioners in small apartment scenarios, and enables a single ducted air conditioner to provide air conditioning for the whole house, while reducing the space occupation and initial installation cost of the ducted air conditioner while ensuring the interior decoration effect.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0006] In some embodiments of this application, a ducted air conditioner is provided, comprising: a housing with an internal mounting cavity, wherein a first air outlet and a return air outlet are provided on the housing; a fan disposed in the mounting cavity to provide power for gas flow; a heat exchanger disposed in the mounting cavity to exchange heat with the flowing gas; and an air duct assembly comprising: a first air duct portion fixedly disposed on the housing, the first air duct portion being located on the air outlet side of the first air outlet; and a second air duct portion detachably connected to the first air duct portion, the second air duct portion having a first mounting position and a second mounting position.

[0007] When the second air duct is in the first installation position, the second air duct is located beside the first air outlet. The air flowing out from the first air outlet is turned by the first air duct to flow to the second air duct beside it, and the air duct machine performs side air discharge.

[0008] When the second air duct is in the second installation position, the second air duct is located on the air outlet side of the first air outlet. The air flowing out from the first air outlet flows through the first air duct and the second air duct in sequence, and the air duct machine performs front air outlet.

[0009] The above technical solution has the following advantages or beneficial effects: by using the detachable connection method of the second air duct, the installation position of the second air duct can be changed, thereby changing the air outlet direction of the duct unit, so that the duct unit can adapt to different installation and use scenarios.

[0010] In some embodiments of this application, the first air duct is provided with a first opening, the first opening is located on the air outlet side of the first air outlet, and the first opening has a blocked state and an open state; when the second air duct is in the first installation position, the first opening is blocked; when the second air duct is in the second installation position, the first opening is open.

[0011] Another technical solution among the above-mentioned technical solutions has the following advantages or beneficial effects:

[0012] Depending on the specific application scenario of the ducted air conditioner, if the ducted air conditioner needs to adopt a side-discharge airflow configuration, the second air duct section is installed next to the first air duct section, and the first opening is sealed. The air flowing out from the first air outlet flows through the first air duct section to the second air duct section on the side.

[0013] Depending on the specific application scenario of the ducted air conditioner, if the ducted air conditioner needs to adopt a front-outlet configuration, the second air duct section is installed in front of the first air duct section. The breakable sheet metal part at the first opening is removed, and the first opening is opened. The air flowing out from the first air outlet flows directly through the first air duct section and the second air duct section.

[0014] Depending on the installation scenario of the ducted air conditioner, different air outlet patterns can be achieved by changing the opening and closing state of the first opening.

[0015] In some embodiments of this application, the width of the second air duct is greater than the width of the first air duct, and when the second air duct is in the first installation position, the second air duct is connected to the first air duct and the housing.

[0016] Another technical solution described above has the following advantages or beneficial effects: When the second air duct is in the first installation position, it is fixedly installed across the first air duct and the side wall of the casing. This increases the outlet cross-sectional size of the second air duct, ensuring sufficient airflow. By utilizing the side space of the casing, the outlet cross-section is widened, minimizing the depth L of the ducted air conditioner while ensuring sufficient airflow capacity.

[0017] In some embodiments of this application, the second air duct includes a plurality of second air outlets, and a shielding part is provided at the second air outlet directly opposite the first air duct.

[0018] Another technical solution described above has the following advantages or beneficial effects: When the second air duct is installed on the side end of the first air duct, a portion of the second air outlets faces the end air outlet of the first air duct, resulting in a large air intake volume for this portion of the second air outlets; another portion of the second air outlets faces the side wall of the casing, resulting in a small air intake volume for this portion of the second air outlets. By providing a shielding part, the air volume of multiple second air outlets can be made uniform, thereby ensuring uniform air volume in each room.

[0019] In some embodiments of this application, the second air duct includes a plurality of second air outlets, and a guide portion is provided inside the second air duct, the guide portion being configured to guide air flowing out of the first air duct to the second air outlet facing the housing.

[0020] Another technical solution in the above technical solution has the following advantages or beneficial effects: when the second air duct is set at the side end of the first air duct, a guide section is provided in the second air duct. The guide section has a streamlined guide surface, which is used to guide the air flowing out of the first air duct to the second air outlet facing the casing, thereby reducing wind resistance and wind noise.

[0021] In some embodiments of this application, the first air duct is divided into a first air duct section of one region and a first air duct section of two regions;

[0022] The second air duct section includes a first-zone second air duct section and a second-zone second air duct section.

The first air valve is configured to regulate the gas flow rate through the first-zone first air duct section and the first-zone second air duct section, and the second air valve is configured to regulate the gas flow rate through the second-zone first air duct section and the second-zone second air duct section.

[0023] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the second air duct section of Zone 1 and the second air duct section of Zone 2 supply air to different spatial areas through different air supply ducts, and the independent control of the first air valve and the second air valve realizes the independent adjustment of the air supply volume of different spatial areas.

[0024] In some embodiments of this application, a second opening is provided on the side of the housing, the second opening having a blocked state and an open state; when the second air duct is in the first installation position, the second opening is open and communicates with the second air duct; when the second air duct is in the second installation position, the second opening is blocked.

[0025] Another technical solution described above has the following advantages or beneficial effects: When the second air duct is in the first installation position, the second opening is open and connected to the second air duct. The second air duct spans the end opening and the second opening of the first air duct. Air that has been heated by the heat exchanger flows into the second air duct through the end opening and the second opening of the first air duct, ensuring the air volume. Simultaneously, the width of the second air duct is reduced, which helps to reduce the overall width of the duct unit.

[0026] In some embodiments of this application, an air conditioning system is provided, including a ducted air conditioner as described above. The room in which the ducted air conditioner is applied includes a corridor area, a rest area, and an activity area. The corridor area connects the rest area and the activity area. The ducted air conditioner is located in the corridor area and adopts a side-discharge airflow form. The second air duct of the first zone supplies air to the rest area through the first zone air supply duct, and the second air duct of the second zone supplies air to the activity area through the second zone air supply duct.

[0027] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the ducted air conditioner is set in the corridor area, the ducted air conditioner adopts the side air outlet form, the second air duct of Zone 1 supplies air to the rest area through the air supply duct of Zone 1, and the second air duct of Zone 2 supplies air to the activity area through the air supply duct of Zone 2, so as to realize independent air supply to different areas.

[0028] In some embodiments of this application, an air conditioning system is provided, including a ducted air conditioner as described above. The room in which the ducted air conditioner is applied includes a corridor area, a rest area, and an activity area. The corridor area connects the rest area and the activity area. The ducted air conditioner is located in the activity area and adopts a front-discharge airflow configuration. The second air duct section of the first zone supplies air to the rest area through a first-zone air supply duct, and the second air duct section of the second zone supplies air to the activity area through a second-zone air supply duct.

[0029] Another technical solution mentioned above has the following advantages or beneficial effects: the ducted air handling unit is installed on the restaurant ceiling. The ducted air handling unit adopts a front-discharge airflow design, with the second air duct section of Zone 1 supplying air to the rest area through the Zone 1 air supply duct, and the second air duct section of Zone 2 supplying air to the activity area through the Zone 2 air supply duct, thus achieving independent air supply to different areas.

[0030] In some embodiments of this application, the ducted air conditioner further includes: a first sensor disposed in the rest area and configured to detect the temperature and humidity of the air in the rest area; a second sensor disposed at the return air inlet and configured to detect the temperature and humidity of the air at the return air inlet; and a controller configured to control the opening angle of the first air valve based on the data fed back by the first sensor, and further configured to control the opening angle of the second air valve based on the data fed back by the second sensor.

[0031] Another technical solution described above has the following advantages or beneficial effects: When the ducted air conditioner operates in daytime energy-saving mode, the controller uses the feedback data from the second sensor as the control parameter. When the ducted air conditioner operates in nighttime energy-saving mode or gentle breeze sleep mode, the controller uses the feedback data from the first sensor as the control parameter. This satisfies different air supply needs of users.

[0064] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application.

[0066] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0067] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0070] In some embodiments of this application, an air conditioner is provided that performs a refrigeration cycle by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

[0071] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0072] The expansion valve expands the high-temperature, high-pressure liquid refrigerant that condenses in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0073] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and the expansion valve can be provided in either the indoor or outdoor unit.

[0074] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0075] In some embodiments of this application, the indoor unit of the air conditioner is a ducted air conditioner 50. For example, the ducted air conditioner 50 is a medium static pressure ducted air conditioner or a high static pressure ducted air conditioner. Figure 1 This is a structural diagram of a ducted air conditioner 50 viewed from above. Figure 2 This is a structural diagram of a ducted air conditioner 50 viewed from below. Figure 3 This is an exploded view of a ductless air conditioner 50. Figure 5 and Figure 6 These are two different internal layout diagrams for the duct air conditioner 50.

[0076] The ducted air conditioner 50 includes a housing 100. The housing 100 is a sheet metal part. The housing 100 has a flat rectangular structure, forming the external outline of the ducted air conditioner 50. An installation cavity is formed inside the housing 100.

[0077] The housing 100 is provided with a first air outlet 110, which communicates with the mounting cavity. For example, the first air outlet 110 is located on the front side of the housing 100.

[0078] The housing 100 is provided with a return air vent 120, which communicates with the mounting cavity. For example, the return air vent 120 is located on the rear side of the housing 100, in which case the ducted air handling unit 50 returns air from the rear. As another example, the return air vent 120 is located on the bottom side of the housing 100, in which case the ducted air handling unit 50 returns air from the bottom.

[0079] The ducted air handling unit 50 also includes a fan 200. The fan 200 is disposed within the mounting cavity. The fan 200 is configured to provide power for airflow. Outside air flows into the mounting cavity through the return air inlet 120 under the action of the fan 200, and then flows out from the first air outlet 110.

[0080] The ducted air handling unit 50 also includes a heat exchanger 300. The heat exchanger 300 is disposed within the mounting cavity. The heat exchanger 300 is configured to exchange heat with flowing air to cool or heat the air. In some embodiments, a fan 200 is disposed on the return air side of the heat exchanger 300.

[0081] For example, heat exchanger 300 is a plate heat exchanger. The plate heat exchanger is set at an angle, which increases the volume of heat exchanger 300 in a limited space, which helps to improve the heat exchange effect.

[0082] The duct unit 50 also includes a duct assembly 400. Figure 9 This is a structural diagram of the air duct assembly 400 as viewed from the air outlet side. Figure 10 This is a structural diagram of the air duct assembly 400 as viewed from the air inlet side. Figure 11 This is an exploded view of the air duct assembly 400.

[0083] The air duct assembly 400 includes a first air duct section 410. The first air duct section 410 has an elongated structure and is fixedly mounted on the housing 100 by screws or other means. The first air duct section 410 is located on the air outlet side of the first air outlet 110. In other words, the first air duct section 410 is located on the front side of the housing 100. An air duct for gas flow is formed inside the first air duct section 410, and the first air outlet 110 communicates with the internal air duct of the first air duct section 410.

[0084] The air duct assembly 400 also includes a second air duct section 420. The second air duct section 420 is detachably connected to the first air duct section 410. An air duct for gas flow is formed within the second air duct section 420. The internal air duct of the first air duct section 410 communicates with the internal air duct of the second air duct section 420. Air flowing out from the first air outlet 110 flows sequentially through the first air duct section 410 and the second air duct section 420 into the room to regulate the indoor air.

[0085] The second air duct section 420 has a first installation position. (See reference...) Figure 1 and Figure 5 When the second air duct section 420 is in the first installation position, the second air duct section 420 is located beside the first air outlet 110. The air flowing out from the first air outlet 110 is turned by the first air duct section 410 to flow to the second air duct section 420 on the side, and the air duct unit 50 performs side air discharge.

[0086] In other words, the second air duct section 420 is located on the left and / or right side of the housing 100. The air flowing out from the first air outlet 110 first flows into the first air duct section 410. At this time, the side of the first air duct section 410 facing the first air outlet 110 is closed. The air flowing into the first air duct section 410 flows to the left and / or right side of the first air duct section 410 until it flows into the second air duct section 420 on the corresponding side, and then flows into the room from the second air duct section 420.

[0087] The second air duct section 420 has a second installation position. (See reference...) Figure 8 When the second air duct section 420 is in the second installation position, the second air duct section 420 is located on the air outlet side of the first air outlet 110. The air flowing out from the first air outlet 110 flows through the first air duct section 410 and the second air duct section 420 in sequence, and the air duct unit 50 performs front air outlet.

[0088] In other words, the first air duct section 410 is located on the front side of the housing 100, and the second air duct section 420 is located on the front side of the first air duct section 410. The air flowing out from the first air outlet 110 flows forward sequentially through the first air duct section 410 and the second air duct section 420, and then flows into the room from the second air duct section 420.

[0089] By using the detachable connection of the second air duct section 420, the installation position of the second air duct section 420 can be changed, thereby changing the air outlet direction of the duct unit 50, so that the duct unit 50 can adapt to different installation and usage scenarios.

[0090] In some embodiments of this application, the duct air conditioner 50 is used in small-area residential and commercial applications, as described above. Figure 16 The room in which the duct air conditioner 50 is used includes a corridor area 30, a rest area 10 and an activity area 20. The corridor area 30 connects the rest area 10 and the activity area 20.

[0091] For example, in a residential setting, the multiple bedrooms 11 within a room are collectively referred to as the rest area 10, while the living room 22 and dining room 21 are collectively referred to as the activity area 20. One end of the corridor area 30 connects to the rest area 10, and the other end connects to the activity area 20. Because medium / high static pressure duct units are relatively thick, concealing them in the ceiling would significantly reduce the room's ceiling height, making them unsuitable for locations requiring large-area ceiling concealment. To achieve installation in small rooms without affecting the interior decoration, the duct unit 50 is concealed in the ceiling in small areas such as the corridor or dining room 21.

[0092] In some embodiments of this application, reference is made to Figure 16 The ducted air conditioner 50 is suspended from the ceiling of the corridor area 30. The length of the ducted air conditioner 50 extends along the length of the corridor area 30. Second air duct sections 420 are installed on both the left and right sides of the ducted air conditioner 50. The ducted air conditioner 50 adopts a side-discharge air type to facilitate the air supply of the ducted air conditioner 50 to the rest area 10 and activity area 20 on the left and right sides.

[0093] The ducted air conditioner 50 features air outlets on both the left and right sides, with no intersecting or obstructing air supply ducts, making it easy to install.

[0094] The ducted air handling unit 50 adopts a bottom-side return air configuration, as per [reference]. Figure 2 To avoid the return air duct occupying 50mm of the width of the duct unit.

[0095] In some embodiments of this application, reference is made to Figure 17 The ducted air conditioner 50 is suspended from the ceiling of the restaurant 21. A second air duct section 420 is installed on the front side of the ducted air conditioner 50. The ducted air conditioner 50 adopts a front-side air outlet form, which facilitates the second air duct section 420 to supply air to the rest area 10 and the activity area 20 through the air supply duct.

[0096] The ducted air conditioner 50 uses a front-side air supply method, which helps to avoid the beam between the dining room 21 and the living room 22, and avoids drilling holes through the wall when installing the duct.

[0097] In some embodiments of this application, reference is made to Figure 3 and Figure 10The first air duct section 410 is provided with a first opening 418, which is located on the air outlet side of the first air outlet 110. The first opening 418 has a blocked state and an open state.

[0098] When the second air duct section 420 is in the first installation position, the first opening 418 is blocked. When the second air duct section 420 is in the second installation position, the first opening 418 is open.

[0099] For example, a breakable sheet metal part 417 is provided at the first opening 418. For example, the first opening 418 is rectangular. When the duct unit 50 leaves the factory, the first opening 418 is covered with the breakable sheet metal part 417.

[0100] Depending on the specific application scenario of the ducted air conditioner 50, if the ducted air conditioner 50 needs to adopt such... Figure 5 In the side-exit configuration shown, the second air duct section 420 is installed beside the first air duct section 410, the breakable sheet metal part 417 at the first opening 418 remains in its factory condition, and the first opening 418 is sealed. Air flowing out from the first air outlet 110 flows through the first air duct section 410 to the side of the second air duct section 420.

[0101] Depending on the specific application scenario of the ducted air conditioner 50, if the ducted air conditioner 50 needs to adopt such... Figure 8 In the front-exit configuration shown, the second air duct section 420 is installed in front of the first air duct section 410. The breakable sheet metal part 417 at the first opening 418 is removed, and the first opening 418 is opened. The air flowing out from the first air outlet 110 flows directly through the first air duct section 410 and the second air duct section 420.

[0102] Depending on the installation scenario of the duct unit 50, different air outlet patterns of the duct unit 50 can be achieved by changing the opening and closing state of the first opening 418.

[0103] In some embodiments of this application, reference is made to Figure 11 and Figure 12 The left and right ends of the first air duct section 410 are open openings 416. When the second air duct section 420 is installed at the left and right ends of the first air duct section 410, the air in the first air duct section 410 flows into the second air duct section 420 through the open openings 416.

[0104] When it is necessary to install the second air duct section 420 on the front side of the first air duct section 410, refer to Figure 8 Remove the breakable sheet metal part 417, install the breakable sheet metal part 417 to the left and right ends of the first air duct part 410, and close the openings 416 at the left and right ends of the first air duct part 410.

[0105] The open ends 416 of the left and right sides of the first air duct section 410 are sealed by using a breakable sheet metal part 417, which saves parts and reduces costs.

[0106] In some embodiments of this application, reference is made to Figure 1 The width W2 of the second air duct section 420 is greater than the width W1 of the first air duct section 410. (Refer to...) Figure 10 When the second air duct section 420 is in the first installation position, the second air duct section 420 is fixedly connected to the first air duct section 410 and the housing 100.

[0107] In other words, when the second air duct section 420 is in the first installation position, it is fixedly installed across the side wall of the first air duct section 410 and the housing 100. This increases the outlet cross-sectional size of the second air duct section 420, ensuring sufficient airflow. By utilizing the side space of the housing 100, the outlet cross-section is widened, minimizing the depth L of the ducted air conditioner 50 while maintaining sufficient airflow capacity.

[0108] In some embodiments of this application, referring to FIG10, the second air duct section 420 includes a plurality of second air outlets 423. The plurality of second air outlets 423 are connected to different air supply ducts to supply air to different rooms.

[0109] In some embodiments of this application, reference is made to Figure 10 A shielding part 426 is provided at the second air outlet 423 directly opposite the first air duct 410. For example, the shielding part 426 is a baffle structure used to block a part of the air outlet area of ​​the second air outlet 423.

[0110] When the second air duct section 420 is installed on the side end of the first air duct section 410, a portion of the second air outlets 423 face the end air outlet 416 of the first air duct section 410, and this portion of the second air outlets 423 has a large air intake; another portion of the second air outlets 423 faces the side wall of the casing 100, and this portion of the second air outlets 423 has a small air intake. By providing the shielding part 426, the air volume of the multiple second air outlets 423 can be made uniform, thereby ensuring uniform air volume in each room.

[0111] When the second air duct section 420 is located in front of the first air duct section 410, the second air outlet 423 does not need to be provided with a shielding section 426.

[0112] In some embodiments of this application, reference is made to Figure 13 The second air duct section 420 includes a plurality of second air outlets 423. A guide section 427 is provided inside the second air duct section 420. The guide section 427 is configured to guide the air flowing out of the first air duct section 410 to the second air outlet 423 facing the housing 100.

[0113] In other words, when the second air duct section 420 is provided at the side end of the first air duct section 410, a guide section 427 is provided inside the second air duct section 420. The guide section 427 has a streamlined guide surface, which is used to guide the air flowing out of the first air duct section 410 to the second air outlet 423 facing the casing 100, thereby reducing wind resistance and wind noise.

[0114] In some embodiments of this application, reference is made to Figure 7 The casing 100 has a second opening 130 on its side, which can be in a blocked state or an open state. The second opening 130 is located on the air outlet side of the heat exchanger 300.

[0115] When the second air duct section 420 is in the first installation position, the second opening 130 is open and communicates with the second air duct section 420. The second air duct section 420 spans the end opening 416 of the first air duct section 410 and the second opening 130. Air that has been heated by the heat exchanger 300 flows into the second air duct section 420 through the end opening 416 of the first air duct section 410 and the second opening 130, ensuring the air volume. At the same time, the width dimension W0 of the second air duct section 420 is reduced, which helps to reduce the width dimension of the entire duct unit 50.

[0116] When the second air duct section 420 is in the second installation position, both the second opening 130 and the end opening 416 of the first air duct section 410 are blocked.

[0117] In some embodiments of this application, a breakable sheet metal part is provided at the second opening 130. Depending on the actual installation scenario of the air duct machine 50, if the second air duct part 420 needs to be installed on the side end of the first air duct part 410, the sheet metal part is broken to open the second opening 130.

[0118] In some embodiments of this application, reference is made to Figure 7 A third air valve 540 is provided at the end opening 416 and the second opening 130 of the first air duct section 410. The air volume is adjusted by controlling the opening angle of the third air valve 540.

[0119] In some embodiments of this application, reference is made to Figure 11 The first air duct section 410 is divided into a first air duct section 411 and a second air duct section 412 by a partition section 413. The first air duct section 411 and the second air duct section 412 are arranged sequentially along the length of the first air duct section 410. Both the first air duct section 411 and the second air duct section 412 are connected to the first air outlet 110.

[0120] The second air duct section 420 includes a first-zone second air duct section 421 and a second-zone second air duct section 422. The first-zone first air duct section 411 is connected to the first-zone second air duct section 421, and the second-zone first air duct section 412 is connected to the second-zone second air duct section 422.

[0121] Reference Figure 5 The air flowing out from the first air outlet 110 has two paths: one path flows out through the first air duct section 411 and the second air duct section 421 of the first zone, and the other path flows out through the first air duct section 412 and the second air duct section 422 of the second zone.

[0122] Reference Figure 3 The ducted air handling unit 50 also includes a valve assembly 500, which is disposed at the first air outlet 110. The valve assembly 500 includes a first valve 510 and a second valve 520. The first valve 510 is configured to regulate the gas flow through the first air duct section 411 and the second air duct section 421 of the first zone. The second valve 520 is configured to regulate the gas flow through the first air duct section 412 and the second air duct section 422 of the second zone.

[0123] The second air duct section 421 in Zone 1 and the second air duct section 422 in Zone 2 supply air to different spatial areas through different air supply ducts. The air supply volume of different spatial areas can be independently adjusted through the independent control of the first air valve 510 and the second air valve 520.

[0124] In some embodiments of this application, reference is made to Figure 6 The damper assembly 500 is disposed within the first air duct section 410. The first damper 510 is disposed obliquely within the first air duct section 411 of zone one, and the second damper 520 is disposed obliquely within the first air duct section 412 of zone two. The first damper 510 and the second damper 520 are arranged in a V-shape. In other words, along the air outlet direction of the first air outlet 110, the ends of the first damper 510 and the second damper 520 are close to each other.

[0125] When only one of the second air duct sections 420 is needed for air supply, the air valve on the opposite side acts as a windbreak and guide, changing the air field arrangement within the air duct.

[0126] For example, if only air needs to be supplied from the second air duct section 421 of Zone 1, the second air valve 520 will be closed, and the air flowing out from the first air outlet 110 will flow into the second air duct section 421 of Zone 1 through the first air valve 510.

[0127] In some embodiments of this application, reference is made to Figure 12The first air duct section 410 includes a first outer shell 414 and a first inner liner 415, with the first outer shell 414 fixedly disposed on the outside of the first inner liner 415. A sealing gasket is provided on the contact surface between the two to prevent air leakage. The first inner liner 415 is made of thermal insulation material to form an air duct. A partition 413 is provided on the first inner liner 415 to divide the internal air duct of the first air duct into a first air duct section 411 and a second air duct section 422.

[0128] The second air duct section 420 includes a second outer shell 424 and a second inner liner 425, with the second outer shell 424 fixedly disposed on the outside of the second inner liner 425. A sealing gasket is provided on the contact surface between the two to prevent air leakage. The second inner liner 425 is made of thermal insulation material to form an air duct.

[0129] In some embodiments of this application, reference is made to Figure 1 and Figure 10 The second air duct section 420 is provided with a clearance groove 428, and the side wall of the air duct unit 50 is provided with a lifting section 140 for lifting. The lifting section 140 is located inside the clearance groove 428, thus isolating the lifting section 140 from the outside of the air duct. For example, the lifting section 140 is a hook.

[0130] In some embodiments of this application, reference is made to Figure 1 A fresh air inlet 150 is provided on the side wall of the housing 100, and the fresh air inlet 150 is connected to the air inlet space of the heat exchanger 300. The ducted air conditioner 50 can selectively install a fresh air module. When the fresh air function is required, the fresh air module is installed at the fresh air inlet 150, and there is no interference between the fresh air module and the duct assembly 400.

[0131] In some embodiments of this application, reference is made to Figure 4 , Figure 14 as well as Figure 15 The damper assembly 500 includes a mounting part 530, which is a mounting bracket structure and is fixed at the first air outlet 110. The first damper 510 and the second damper 520 are fixedly mounted on the mounting part 530.

[0132] The first air valve 510 and the second air valve 520 are, but are not limited to, louvered forms. The air valves are driven by a motor and adjust their opening degree according to the air supply demand.

[0133] In some embodiments of this application, an air conditioning system is provided, including the ducted air conditioner 50 disclosed in the above embodiments. (See also...) Figure 16The room in which the ducted air conditioner 50 is used includes a corridor area 30, a rest area 10, and an activity area 20. The corridor area 30 connects the rest area 10 and the activity area 20. For example, in a residence, the multiple bedrooms 11 in the room are collectively referred to as the rest area 10, and the living room 22 and dining room 21 in the room are collectively referred to as the activity area 20.

[0134] The ducted air conditioner 50 is installed in the corridor area 30. The ducted air conditioner 50 adopts a side-discharge form. The second air duct section 421 of Zone 1 supplies air to the rest area 10 through the Zone 1 air supply duct, and the second air duct section 422 of Zone 2 supplies air to the activity area 20 through the Zone 2 air supply duct, so as to realize independent air supply to different areas.

[0135] In some embodiments of this application, reference is made to Figure 17 The ducted air conditioner 50 is installed in the activity area 20, for example, on the ceiling of the restaurant 21. The ducted air conditioner 50 adopts a front-discharge air type. The second air duct section 421 of Zone 1 supplies air to the rest area 10 through the Zone 1 air supply duct, and the second air duct section 422 of Zone 2 supplies air to the activity area 20 through the Zone 2 air supply duct, so as to achieve independent air supply to different areas.

[0136] In some embodiments of this application, the duct air handling unit 50 is equipped with a wired controller that communicates with the air valve assembly 500.

[0137] The ducted air conditioner 50 has a daytime energy-saving operation mode. During the day, people are generally active in the living room 22, dining room 21, and other activity areas 20, at which time only air needs to be supplied to the activity areas 20. By selecting the daytime energy-saving operation mode through the wired controller, the second air valve 520 opens and the first air valve 510 closes, and the ducted air conditioner 50 supplies air to the activity areas 20 through the second air duct section 422 of the second zone.

[0138] The ducted air conditioner 50 has a nighttime energy-saving operation mode. At night, people generally rest in the bedroom 11, at which time only air needs to be supplied to the resting area 10. By selecting the nighttime energy-saving operation mode through the wired controller, the first air valve 510 opens and the second air valve 520 closes, and the ducted air conditioner 50 supplies air to the resting area 10 through the second air duct section 421 of the first zone.

[0139] The ducted air conditioner 50 has a gentle breeze sleep mode. When the gentle breeze sleep mode is selected via the wired controller, the first air valve 510 opens at a small angle, and the second air valve 520 opens. The ducted air conditioner 50 simultaneously supplies air to the rest area 10 and the activity area 20. The air volume in the rest area 10 is small to achieve a gentle breeze, while the air volume in the activity area 20 is large. The air in the activity area 20 flows into the rest area 10, regulating the temperature and humidity in the rest area 10.

[0140] In some embodiments of this application, reference is made to Figure 16The duct unit 50 also includes a first sensor 41, which is located in the rest area 10 and configured to detect the temperature and humidity of the air in the rest area 10.

[0141] Reference Figure 2 The duct unit 50 also includes a second sensor 42, which is located at the return air vent 120 and is configured to detect the temperature and humidity of the air at the return air vent 120.

[0142] The duct unit 50 also includes a controller, which is configured to control the opening angle of the first air valve 510 based on data fed back by the first sensor 41, and is also configured to control the opening angle of the second air valve 520 based on data fed back by the second sensor 42.

[0143] When the duct unit 50 is in daytime energy-saving operation mode, the controller uses the feedback data from the second sensor 42 as the control parameters.

[0144] When the ducted air conditioner 50 is in nighttime energy-saving operation mode or gentle breeze sleep operation mode, the controller uses the feedback data from the first sensor 41 as the control parameter.

[0145] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0146] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
