[0034] Reference below Figure 1-Figure 5 An air conditioning system 100 according to an embodiment of the present invention is described.

[0035] like Figure 1-Figure 5 As shown, the air conditioning system 100 according to the embodiment of the present invention includes: an air conditioner 10, an exhaust duct 20 and a booster fan 30. The air conditioner 10 has an air supply duct 11 and an exhaust duct 12. The air supply duct 11 is connected to the room for supplying air to the room. The exhaust duct 12 has an exhaust port 122 for exhausting air outside the air conditioner 10. The exhaust duct 12 is arranged at an interval from the air supply duct 11, so that the interior of the air conditioner 10 can realize the diversion of indoor air, which is convenient for heat exchange between the two air flows, so as to cool or heat the indoor air. At the same time, the integration level of the air conditioner 10 can be improved. On the basis of improving the cooling effect or heating effect on the indoor air, it is beneficial to improve the space utilization rate of the air conditioner 10 and facilitate installation.

[0036] The exhaust duct 20 is disposed outside the air conditioner 10, and one end of the exhaust duct 20 (such as Figure 1 The rear end shown in FIG. 1 is connected to the exhaust port 122, and the other end of the exhaust pipe 20 (as shown in FIG. Figure 1 The front end of the exhaust duct 12 is connected to the common flue 300, so that the indoor air in the exhaust duct 12 can be discharged to the common flue 300 through the exhaust pipe 20. Compared with drilling holes in the wall to exhaust to the outside, and compared with setting a mounting position outside the wall to install the air conditioner 10, the installation and arrangement of the air conditioner 10 can be more convenient, the application range of the air conditioner 10 can be increased, and the aesthetics of the wall can be improved.

[0037] The booster fan 30 is arranged in the exhaust duct 20. The indoor air in the exhaust duct 12 needs to flow through the booster fan 30 and then be discharged to the common flue 300. The booster fan 30 can increase the air flow rate flowing through the booster fan 30 to increase the exhaust volume of the air conditioner 10 to the common flue 300, which can prevent the indoor air from being unable to be fully discharged due to excessive smoke pressure in the common flue 300, thereby improving the performance of the air conditioner 10 and improving the user experience.

[0038] According to the air conditioning system 100 of the embodiment of the present invention, an exhaust duct 20 is provided, and the two ends of the exhaust duct 20 are respectively connected to the public flue 300 and the exhaust duct 12 of the air conditioner 10, so that the air conditioner 10 can exhaust air through the public flue 300, which can reduce the utilization of the wall surface by the air conditioner 10, facilitate the installation and arrangement of the air conditioner 10, and increase the application scope of the air conditioner 10, while improving the aesthetics of the wall surface; by providing a booster fan 30 in the exhaust duct 20, the air flow rate flowing through the booster fan 30 can be increased, thereby increasing the exhaust volume of the air conditioner 10 to the public flue 300, which can prevent the indoor air from being unable to be fully discharged due to the excessive smoke pressure in the public flue 300, and can improve the use performance of the air conditioner 10 and the user experience.

[0039] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the air conditioning system 100 also includes: a wind speed detection device 40, and the booster fan 30 is arranged in the exhaust duct 20, so that when the exhaust duct 12 exhausts air to the common flue 300, the air can fully flow through the booster fan 30, thereby improving the boosting effect of the booster fan 30 on the indoor air, so as to maximize the air flow rate flowing through the booster fan 30, thereby increasing the exhaust volume of the air conditioner 10 to the common flue 300.

[0040] The wind speed detection device 40 is disposed on a side of the booster fan 30 close to the air conditioner 10 (eg Figure 1 The rear side shown in the figure can prevent the smoke in the common flue 300 from interfering with the operation of the wind speed detection device 40. The wind speed detection device 40 is used to detect the wind speed in the exhaust duct 20, thereby improving the accuracy of the wind speed detection device 40 in detecting the wind speed, and the wind speed detection device 40 communicates with the booster fan 30, and then the wind speed detection device 40 can detect the wind speed in the exhaust duct 20 to adjust the rotation speed of the booster fan 30, so that the rotation speed of the booster fan 30 can be increased when the wind speed in the exhaust duct 20 is low, and the rotation speed of the booster fan 30 can be reduced when the wind speed in the exhaust duct 20 is high, thereby improving the intelligence of the air-conditioning system 100 and improving the performance of the air conditioner 10.

[0041] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, an exhaust fan wheel 123 is provided in the exhaust duct 12, and the air conditioner 10 can control the rotation of the exhaust fan wheel 123 to discharge the indoor air to the common flue 300 through the exhaust duct 12, and the air in the exhaust duct 12 can be discharged to the outside through the common flue 300 after heat exchange, which can improve the accuracy of indoor temperature regulation and the speed of indoor temperature regulation, which is beneficial to improve the cooling effect or heating effect of the indoor air.

[0042] Among them, the air conditioner 10 can automatically adjust the rotation speed of the exhaust fan wheel 123. For example, when the temperature difference between the indoor temperature and the set temperature of the air conditioner 10 is large, the air conditioner 10 can increase the rotation speed of the exhaust fan wheel 123. When the temperature difference between the indoor temperature and the set temperature of the air conditioner 10 is small, the air conditioner 10 can lower the rotation speed of the exhaust fan wheel 123. The intelligence of the exhaust duct 12 exhaust can be improved. On the basis of improving the cooling effect or heating effect of the air conditioner 10 on the indoor air, the energy consumption of the air conditioner 10 can be reduced. In addition, the user can set the wind speed gear on the operation panel of the air conditioner 10 so that the exhaust fan wheel 123 rotates at a specified speed, thereby improving the user experience.

[0043] like Figure 1-Figure 3 As shown, according to some embodiments of the present invention, an air supply wheel 113 is provided in the air supply duct 11, and the air conditioner 10 can control the rotation of the air supply wheel 113 to allow the indoor air to flow back into the room through the air supply duct 11, thereby realizing indoor circulating air supply, and further enhancing the air conditioner 10's targeted cooling or heating of the indoor air, which is beneficial to improving the cooling effect or heating effect of the indoor air.

[0044] Among them, the air conditioner 10 can adjust the rotation speed of the air supply impeller 113. For example, when the temperature difference between the indoor temperature and the set temperature of the air conditioner 10 is large, the air conditioner 10 can increase the rotation speed of the air supply impeller 113. When the temperature difference between the indoor temperature and the set temperature of the air conditioner 10 is small, the air conditioner 10 can lower the rotation speed of the air supply impeller 113. The intelligence of the air supply in the air supply duct 11 can be improved. On the basis of improving the cooling effect or heating effect of the air conditioner 10 on the indoor air, the energy consumption of the air conditioner 10 can be reduced. In addition, the user can set the wind speed gear on the operation panel of the air conditioner 10 so that the air supply impeller 113 rotates at a specified speed, thereby improving the user experience.

[0045] like Figure 1-Figure 3 As shown, according to some embodiments of the present invention, the air supply duct 11 has a return air outlet 111 and an air supply outlet 112. The air supply outlet 112 is connected to the room, and the return air outlet 111 can be connected to the indoor air, so that the indoor air can enter the air supply duct 11 through the return air outlet 111 and flow back to the room through the air supply outlet 112, thereby realizing circulating air supply to the room, and is beneficial to enhancing the targeted cooling or heating of the indoor air by the air conditioner 10, and improving the cooling effect or heating effect of the indoor air; the air supply outlet 112 is connected to the room, and the return air outlet 111 can be connected to the outdoor air, so that the outdoor air can enter the air supply duct 11 through the return air outlet 111 and flow into the room through the air supply outlet 112, thereby realizing the supply of fresh air to the room to improve the freshness of the indoor air.

[0046] Of course, the return air outlet 111 can be connected to indoor air and outdoor air at the same time, which is conducive to the air conditioner 10 to automatically switch the air supply mode (such as circulating air supply or fresh air supply, etc.) according to the indoor environment, and it is convenient for the user to operate the operation panel of the air conditioner 10 to switch the air supply mode according to the user's needs, which can improve the applicability of the air conditioner 10 and improve the user's experience.

[0047] like Figure 2 As shown, in some examples, the number of return air vents 111 can be multiple, a part of the multiple return air vents 111 can be connected to outdoor air, and another part of the multiple return air vents 111 can be connected to indoor air, and then, only the return air vents 111 connected to the indoor air need to be closed separately, and the outdoor air can be allowed to flow through the supply air duct 11, so as to realize the supply of fresh air to the room, or, only the return air vents 111 connected to the outdoor air need to be closed separately, and the indoor air can be allowed to flow through the supply air duct 11, so as to realize the circulating air supply to the room, which is convenient for switching the air supply mode of the supply air duct 11 to the room.

[0048] Of course, multiple return air vents 111 can be connected to outdoor air respectively, which can increase the air intake of outdoor air and thus improve the effect of supplying fresh air to the room. Alternatively, multiple return air vents 111 can be connected to indoor air respectively, which can increase the return air volume of indoor air and thus improve the effect of circulating air supply to the room, which is beneficial to improving the cooling or heating effect of the indoor air.

[0049] like Figure 1-Figure 3 As shown, according to some embodiments of the present invention, the air conditioner 10 can be installed on a suspended ceiling in a room, and the suspended ceiling has a first opening 210 and a second opening 220. The first opening 210 is used to take in air to the upper part of the suspended ceiling, and the second opening 220 is used to discharge air to the lower part of the suspended ceiling. The exhaust duct 12 has an air inlet 121 for taking in air to the exhaust duct 12. The air inlet 121 of the exhaust duct 12 and the return air outlet 111 of the supply air duct 11 are respectively connected to the first opening 210, so that indoor air can enter the exhaust duct 12 through the first opening 210 and the air inlet 121 in turn, and at the same time, indoor air can enter the supply air duct 11 through the first opening 210 and the return air outlet 111 in turn.

[0050] The air supply duct 11 has an air supply pipe 230, and one end of the air supply pipe 230 (such as Figure 1 The front end of the air supply pipe 230 is connected to the air supply port 112 of the air supply duct 11, and the other end of the air supply pipe 230 (as shown in FIG. Figure 1 The rear end shown in the figure is connected to the second opening 220, so that the air supply port 112 of the air supply duct 11 is connected to the second opening 220 through the air supply pipe 230, so that the air in the air supply duct 11 can flow into the room through the air supply port 112 and the second opening 220 in sequence.

[0051] Among them, the first opening 210 and the second opening 220 are arranged at intervals, which can prevent the first opening 210 from inhaling indoor air near the second opening 220, which is beneficial to increasing the flow range of indoor air in the room, and further improving the indoor circulation air supply effect of the air conditioner 10. When the air conditioner 10 is in cooling or heating mode, the circulation path of the indoor air can be increased to prevent local cooling or heating in the room, which can improve the cooling effect or heating effect on the indoor air.

[0052] like Figure 1 and Figure 2 As shown, in some examples, the air conditioner 10 further includes: a compressor, a control valve 50, a first heat exchanger and a second heat exchanger. The compressor, the first heat exchanger and the second heat exchanger are interconnected through a pipeline. The control valve 50 is arranged on the pipeline, so that the compressor, the first heat exchanger and the second heat exchanger can form a first refrigerant circulation loop. Alternatively, the control valve 50 is arranged on the pipeline, so that the compressor, the second heat exchanger and the first heat exchanger can form a second refrigerant circulation loop.

[0053] Among them, the first heat exchanger can be a condenser, which is used for heat exchange with the air in the exhaust duct 12, and the second heat exchanger can be an evaporator, which is used for heat exchange with the air in the supply duct 11. Under the first refrigerant circulation loop, the first heat exchanger absorbs heat and the second heat exchanger releases heat to achieve heating of the indoor air. Under the second refrigerant circulation loop, the first heat exchanger releases heat and the second heat exchanger absorbs heat to achieve cooling of the indoor air.

[0054] In some examples, the control valve 50 can be a four-way valve, which includes a first connecting port, a second connecting port, a third connecting port and a fourth connecting port, the outlet of the compressor is connected to the first connecting port, the inlet of the compressor is connected to the third connecting port, the first heat exchanger is connected to the fourth connecting port, the second heat exchanger is connected to the second connecting port, and the first heat exchanger and the second heat exchanger are connected through a pipeline, so that the air conditioner 10 can control the connecting valve to connect the first connecting port and the fourth connecting port, and at the same time connect the second connecting port and the third connecting port to form a second refrigerant circulation loop; or, the air conditioner 10 can control the connecting valve to connect the first connecting port and the second connecting port, and at the same time connect the third connecting port and the fourth connecting port to form a first refrigerant circulation loop.

[0055] In some examples, the air conditioning system 100 can be installed in the kitchen to achieve air supply to the kitchen, or to achieve cooling or heating of the kitchen air, thereby improving the user experience; wherein, the number of the first openings 210 can be multiple, which is beneficial to increase the air intake of the air conditioner 10, and the number of the second openings 220 can be multiple, which is beneficial to increase the air supply range of the air conditioner 10. For example, the second opening 220 can be opened on the ceiling in the bathroom to achieve air supply to the bathroom.

[0056] In some examples, the air conditioner 10 can be an integrated unit, which is convenient for indoor installation and later maintenance; the air conditioner 10 can also be a split unit, in which the indoor and outdoor units are both installed indoors, the outdoor unit can be arranged adjacent to the public flue 300 for exhaust, and the indoor unit can be arranged adjacent to the outdoor unit for installation and later maintenance. The indoor unit can also be arranged away from the outdoor unit, which is beneficial to improving the air supply effect of the air conditioner 10, and is beneficial to improving the cooling or heating effect of the indoor air, and is beneficial to the adjacent arrangement of the first opening 210 and the second opening 220, which can reduce the indoor decoration cost.

[0057] like Figure 1-Figure 5 As shown, the control method of the air conditioning system according to an embodiment of the present invention includes:

[0058] S1: Determine the working mode and air supply level of the air conditioner;

[0059] S2: Determine whether to detect the wind speed in the exhaust duct according to the working mode of the air conditioner;

[0060] S3: When detecting the wind speed in the exhaust duct, the working state of the booster fan is controlled according to the difference between the wind speed in the exhaust duct and the set value under the working mode and the air supply gear.

[0061] According to the control method of the air-conditioning system of an embodiment of the present invention, by adopting the above-mentioned air-conditioning system, the air conditioner can be exhausted through a common flue, which can reduce the utilization of the wall by the air conditioner, facilitate the installation and layout of the air conditioner, increase the application range of the air conditioner, and improve the aesthetics of the wall.

[0062] like Figure 1 and Figure 5 As shown, according to some embodiments of the present invention, controlling the working state of the booster fan according to the difference between the wind speed in the exhaust duct and the set value under the working mode and the air supply gear includes:

[0063] When the wind speed in the exhaust duct is less than the preset percentage of the set value under the working mode and the air supply gear, the booster fan is controlled to work;

[0064] When the wind speed in the exhaust duct is greater than or equal to a preset percentage of the set value under the working mode and the air supply gear, the booster fan is controlled to stop working.

[0065] In some embodiments, the air conditioner has multiple operating modes (for example, cooling, heating or air supply), and the air conditioner has multiple air supply gears in each operating mode. In different air supply gears, the rotation speeds of the air supply impeller and the exhaust impeller are different, and thus the theoretical wind speeds of the air supply duct supplying air to the room are different, and the theoretical wind speeds of the exhaust duct exhausting air to the outdoors are different, which is convenient for users to select and for the air conditioner to automatically select to adapt to the environment, thereby helping to improve the working effect of the air conditioner.

[0066] The wind speed in the exhaust duct is the actual wind speed of the exhaust duct exhausting air to the public flue, which is detected in real time by the wind speed detection device; the set value under the working mode and air supply gear is the theoretical wind speed of the exhaust duct exhausting air to the outside when the air conditioner is in a certain air supply gear under a certain working mode.

[0067] It can be understood that the air pressure in the public flue is greater than the indoor air pressure due to the flow of smoke. Therefore, when the air conditioner is in a certain air supply gear under a certain working mode, the actual wind speed of the exhaust duct exhausting air to the public flue is less than the theoretical wind speed. Further, when the wind speed detection device detects that the actual wind speed is less than a preset percentage of the theoretical wind speed, the air conditioner controls the boost fan to work until the actual wind speed is greater than or equal to the preset percentage of the theoretical wind speed. Further, when the wind speed detection device detects that the actual wind speed is greater than or equal to the preset percentage of the theoretical wind speed, the air conditioner controls the boost fan to stop working, which can improve the smoothness of the exhaust from the exhaust duct to the public flue, and thus improve the performance of the air conditioner.

[0068] like Figure 1 and Figure 5 As shown, in some examples, when the wind speed in the exhaust duct is less than a preset percentage of the set value under the working mode and the air supply gear, the booster fan is controlled to work, and then the speed of the booster fan is controlled according to the difference between the wind speed in the exhaust duct and the set value under the working mode and the air supply gear.

[0069] In certain embodiments, if the difference between the wind speed in the exhaust duct and the set value under the working mode and the air supply gear is larger, the air conditioner controls the boost fan to rotate at a higher speed to improve the smoothness of exhausting the exhaust duct to the common flue. If the difference between the wind speed in the exhaust duct and the set value under the working mode and the air supply gear is smaller, the air conditioner lowers the speed of the boost fan accordingly. Based on improving the smoothness of exhausting the exhaust duct to the common flue, the energy consumption of the air conditioner can be reduced.

[0070] According to some embodiments of the present invention, the air conditioning system includes a compressor, and the working modes of the air conditioner include: a heating mode, a cooling mode and a dehumidification mode. In the heating mode, the air conditioning system sends hot air to the room, in the cooling mode, the air conditioning system sends cold air to the room, and in the dehumidification mode, the air conditioner dehumidifies the indoor air; wherein determining the working mode and air supply gear of the air conditioner includes:

[0071] Control the operation of the compressor;

[0072] When the air supply level set by the user is not detected, the difference between the set temperature in the working mode and the ambient temperature is detected, and the air supply level of the air conditioner is selected according to the difference between the set temperature in the working mode and the ambient temperature, and the air conditioner is controlled to supply air to the room according to the air supply level.

[0073] In certain embodiments, after the user selects the operating mode of the air conditioner and enters the set temperature on the operation panel, the user can set the air supply level on the operation panel of the air conditioner according to his or her needs. If the user has not set the air supply level in advance, the air conditioner begins to detect the difference between the set temperature and the ambient temperature, and automatically selects the air supply level according to the size of the difference.

[0074] Among them, if the difference between the set temperature and the ambient temperature is greater, the air conditioner will increase the air supply gear, so that the supply air impeller and the exhaust air impeller both rotate at a higher speed, thereby increasing the air supply speed of the air supply duct and increasing the air supply speed of the exhaust duct, which is beneficial to improving the air conditioner's cooling, heating or dehumidification effect on the indoor air; if the difference between the set temperature and the ambient temperature is smaller, the air conditioner will reduce the air supply gear, so that the supply air impeller and the exhaust air impeller both rotate at a lower speed, thereby reducing energy consumption.

[0075] It should be noted that the dehumidification mode is the cooling mode or heating mode of the air conditioner at low power, that is, when the set temperature is greater than the ambient temperature, the dehumidification mode is the low-power heating mode, and when the set temperature is lower than the ambient temperature, the dehumidification mode is the low-power cooling mode.

[0076] like Figure 1 and Figure 5 As shown, in some examples, when the user sets the air supply level, the air conditioner is controlled to supply air to the room according to the air supply level set by the user.

[0077] In some embodiments, after the user selects the operating mode of the air conditioner and inputs the set temperature on the operation panel, the user can set the air supply level on the operation panel of the air conditioner according to his / her needs to start the air conditioner working.

[0078] like Figure 3 and Figure 5 As shown, according to some embodiments of the present invention, the working mode of the air conditioner also includes an air supply mode. In the air supply mode, the air conditioning system circulates air to the indoor room. In the air supply mode, the wind speed in the exhaust duct is not detected, and the booster fan is controlled to stop working.

[0079] In some embodiments, the booster fan and the exhaust fan wheel both stop working in the air supply mode so that the exhaust duct stops exhausting air to the common flue, and the supply fan wheel starts working so that the indoor air circulates indoors through the supply air duct, thereby realizing circulating air supply to the indoor room by the supply air duct.

[0080] Reference below Figure 2 , Figure 4 and Figure 5 To describe a specific embodiment of the present application, the air conditioning system 100 includes: an air conditioner 10, an exhaust duct 20, a booster fan 30 and a wind speed detection device 40, the air conditioner 10 has an air supply duct 11 and an exhaust duct 12, the air supply duct 11 and the exhaust duct 12 are respectively connected to the room, the exhaust duct 20 is arranged outside the air conditioner 10, and the exhaust duct 12 is connected to the common flue 300 through the exhaust duct 20, the air supply duct 11 is provided with an air supply fan wheel 113, the exhaust duct 12 is provided with an exhaust fan wheel 123, the booster fan 30 is arranged in the exhaust duct 20, and the wind speed detection device 40 is arranged on the side of the booster fan 30 close to the air conditioner 10 (such as Figure 2 rear side shown).

[0081] The air conditioner 10 includes: a compressor, a control valve 50, a condenser and an evaporator. The compressor, the condenser and the evaporator are interconnected through a pipeline. The control valve 50 is arranged on the pipeline. The condenser is arranged close to the exhaust air duct 12, and the evaporator is arranged close to the supply air duct 11. The compressor, the condenser and the evaporator can form a first refrigerant circulation loop, that is, the condenser absorbs heat and the evaporator releases heat, thereby heating the indoor air. Alternatively, the control valve 50 is arranged on the pipeline, so that the compressor, the condenser and the evaporator can form a second refrigerant circulation loop, that is, the condenser releases heat and the evaporator absorbs heat, thereby cooling the indoor air.

[0082] The user can determine that the air conditioner 10 is in cooling mode and input the set temperature on the operation panel. The user can then continue to set the air supply gear of the cooling mode on the operation panel, and then the air conditioner 10 controls the compressor to work and manipulates the control valve 50 so that the compressor, condenser, and evaporator form a second refrigerant circulation loop, that is, the evaporator absorbs heat from the air in the supply air duct 11, and the condenser dissipates heat to the air in the exhaust air duct 12. At the same time, the air conditioner 10 controls the air supply impeller 113 and the exhaust impeller 123 to work, so that the supply air duct 11 supplies air to the room at the wind speed of the supply air gear, and the exhaust air duct 12 exhausts air to the public flue 300 at the wind speed of the supply air gear, thereby realizing cooling of the indoor air.

[0083] Among them, when the air conditioner 10 delivers cold air to the room, the wind speed detection device 40 detects the wind speed in the exhaust duct 20 in real time. After the wind speed in the exhaust duct 20 is less than 90% of the wind speed of the air supply gear, the air conditioner 10 controls the boost fan 30 to work until the wind speed in the exhaust duct 20 is greater than or equal to 90% of the wind speed of the air supply gear, ensuring that the exhaust duct 12 is fully discharged to the public flue 300, which is beneficial to improving the cooling effect of the air conditioner 10 on the indoor air.
