[0044] Appendix Figure 19 The middle arrow indicates the direction of water flow, while the middle arrows in the other attached diagrams indicate the direction of air flow.

[0045] like Figures 1 to 2 , Figures 17 to 22 As shown, this embodiment of the present disclosure provides an air conditioning unit 1, which includes an air conditioning component 20 and an air conditioning fan component 30. The air conditioning component 20 includes a heat exchanger 202 and a first fan 201. The first fan 201 drives airflow through the heat exchanger 202 and then blows it out, which can realize the function of regulating temperature of the air conditioning unit 1.

[0046] Heat exchanger 202 is an indoor heat exchanger, which is connected to the compressor, outdoor heat exchanger 202, and electronic expansion valve via refrigerant piping. The first fan 201 drives airflow through the indoor heat exchanger 202, where heat exchange occurs. The airflow is then blown into the room, regulating the indoor temperature and thus providing a temperature control function.

[0047] Optionally, the air conditioning fan assembly 30 includes a water tank 301 and a water collection component 304. The water tank 301 is used to hold water, and the water collection component 304 is used to receive water from the water tank 301.

[0048] An air cooler is a household appliance that combines the functions of a fan and an air conditioner, providing airflow, cooling, and humidification. Using water as a medium, it can deliver either cool air below room temperature or warm, humid air.

[0049] Optionally, the air conditioning fan assembly 30 includes a first fan 201. That is, the air conditioning assembly 20 and the air conditioning fan assembly 30 share the first fan 201. The first fan 201 can drive airflow to flow sequentially through the water collection component 304 and the heat exchanger 202, and can exchange heat with the water collection component 304 and / or the heat exchanger 202. This can reduce the space occupied by the air conditioning fan assembly 30 inside the air conditioning unit 1.

[0050] Optionally, the air conditioning fan assembly 30 includes a second fan 303, which drives airflow through the water collection component 304 and exchanges heat with it before flowing out. That is, the air conditioning assembly 20 and the air conditioning fan assembly 30 are each provided with an independent fan to drive airflow through the heat exchanger 202 or through the water collection component 304, respectively.

[0051] Optionally, such as Figure 2 As shown, the air conditioning unit 1 includes a housing 10, which defines a receiving cavity 101 having a fresh air inlet 104 and an air outlet. The air conditioning assembly 20 and the air conditioning fan assembly 30 are both located within the receiving cavity 101. That is, the heat exchanger 202, the water tank 301, and the water collection component 304 are all located within the receiving cavity 101. The water tank 301 is used to collect condensate produced by the heat exchanger 202, and the water collection component 304 is used to collect condensate within the water tank 301.

[0052] In this embodiment, the air conditioning fan assembly 30 and the air conditioning assembly 20 can be integrated into a single unit. The water tank 301 within the air conditioning fan assembly 30 collects the condensate produced by the heat exchanger 202 of the air conditioning assembly 20. This not only reduces the temperature of the airflow exiting the air conditioning fan assembly 30, improving its temperature control effect, but also solves the problem of condensate discharge from the air conditioning assembly 20, preventing condensate dripping and causing inconvenience to the user.

[0053] Optionally, the condensate produced by the heat exchanger 202 flows into the water tank 301 through the water inlet pipe 306. The air conditioning unit 1 also includes a water inlet tray, which flows into the water tank 301 through the water inlet pipe 306.

[0054] Optionally, the air conditioning fan assembly 30 includes a first fan 201 or a second fan 303 (hereinafter, the fans included in the air conditioning fan assembly 30 are collectively referred to as fans). The fans can drive the airflow flowing in from the fresh air inlet 104 to flow through the water collection member 304, so as to drive the airflow to exchange heat with the water collection member 304 and then flow out.

[0055] In this embodiment, the receiving cavity 101 is provided with a fresh air inlet 104, through which fresh outdoor air driven by a fan can enter the receiving cavity 101. After entering the receiving cavity 101, the fresh air exchanges heat with the water collection component 304 before flowing into the room through the air outlet. This continuously replenishes fresh air and lowers its temperature. When the air conditioning fan assembly 30 is turned on, it can not only regulate the indoor temperature but also replenish the room with fresh air. By replenishing the fresh air, the indoor air quality can be improved, thus avoiding excessively high indoor carbon dioxide concentrations that could cause drowsiness and fatigue in users.

[0056] Air conditioning unit 1 fully utilizes the condensate generated by air conditioning component 20 during cooling, recycling the condensate resource. This also allows the latent heat generated by air conditioning component 20 to be fully utilized, maximizing its energy efficiency. Simultaneously, the air conditioning fan component 30 introduces fresh air, purifying indoor air while simultaneously controlling temperature and humidity, preventing excessive dryness after prolonged cooling in summer. This meets the user's three-way needs, enhancing the user experience. It improves the user's expectations for energy saving, air purification, and temperature and humidity control in air conditioning unit 1, while also enhancing the overall aesthetics of the indoor unit.

[0057] Optionally, the air conditioning unit 1 also includes a fresh air duct 1041, which is connected to the fresh air inlet 104. Outdoor fresh air flows into the fresh air inlet 104 through the fresh air duct 1041 and then enters the receiving cavity 101.

[0058] Optionally, the receiving cavity 101 includes an upper space 102 and a lower space 103. The heat exchanger 202 and the first fan 201 are both located in the upper space 102, and the water tank 301 is located in the lower space 103.

[0059] In this optional embodiment, the heat exchanger 202 is located above the water tank 301, facilitating the flow of condensate from the heat exchanger 202 into the water tank 301 under gravity. Optionally, the water tank 301 is open, thereby facilitating the flow of water from the water collection component 304 into the water tank 301.

[0060] Optionally, the water collection component 304 is located above the water tank 301. This allows excess condensate in the water collection component 304 to flow into the water tank 301 under gravity, thereby achieving the recycling of condensate.

[0061] Optionally, the air conditioning unit 1 also includes a drive device 305. The drive device 305 is connected to both the water tank 301 and the water collection component 304, and is able to drive the water in the water tank 301 to flow to the water collection component 304.

[0062] In this optional embodiment, the water tank 301 can collect the condensate produced by the heat exchanger 202, and the drive device 305 drives the condensate collected in the water tank 301 to the water collection component 304. The water collection component 304 can absorb the condensate and humidify the airflow through a fan. The humidified airflow flows into the room, humidifying the indoor environment. This not only solves the problem of condensate discharge from the air conditioning component 20, but also utilizes the condensate to achieve humidification through the structure of the air conditioning fan component 30, making it more environmentally friendly and energy-efficient. The drive device 305 can be a water pump, etc.

[0063] Optionally, the 304 water-collecting component can not only absorb and evaporate water, but also filter impurities in the water, increasing its cleanliness.

[0064] The water collection component 304 can be made of high-density fiber material or a wet curtain to facilitate the absorption of condensate.

[0065] In one specific embodiment, such as Figure 19 As shown, the water collection component 304 is located within the upper space 102. That is to say, the air conditioning fan assembly 30 and the air conditioning assembly 20 share the first fan 201.

[0066] Along the airflow direction within the upper space 102, the water collection component 304, the heat exchanger 202, and the first fan 201 are arranged sequentially. The first fan 201 can drive the airflow flowing into the fresh air inlet 104 to flow sequentially through the water collection component 304 and the heat exchanger 202.

[0067] In this embodiment, the first fan 201 can drive the airflow entering from the fresh air inlet 104 to flow simultaneously through the water accumulation component 304 and the heat exchanger 202. The second fan 303, which is not required to be additionally installed as an air conditioning fan assembly 30, reduces the number of components within the air conditioning unit 1. This simplifies the structure of the air conditioning unit 1 and saves energy.

[0068] Optionally, the water collection element 304 is attached to the surface of the heat exchanger 202.

[0069] In this embodiment, "attaching" refers to being in contact with or close to the heat exchanger 202. The water collection component 304 abuts against the surface of the heat exchanger 202 to facilitate heat exchange between the water collection component 304 and the heat exchanger 202. This further reduces the temperature of the water collection component 304, thereby ensuring the temperature of the airflow exiting the air conditioning unit 1.

[0070] Optionally, the first fan 201 is a cross-flow fan. The cross-flow fan can deliver the air outlet of the air conditioning unit 1 to a farther location, thereby increasing the air outlet range of the air conditioning unit 1.

[0071] In another specific embodiment, the air conditioning assembly includes a first fan 201. A water collection component 304 is located in the lower space 103, and the air conditioning fan assembly 30 includes a second fan 303, which is also located in the lower space 103. The lower space 103 is provided with a fresh air inlet 104 and an air outlet, and the second fan 303 can drive airflow to flow from the fresh air inlet 104 into the water collection component 304 and then out through the air outlet.

[0072] In this embodiment, the air conditioning fan assembly 30 is equipped with an independent second fan 303, which can drive fresh air to flow through the water collection component 304 and then out through the air outlet. With this configuration, the air conditioning fan assembly 30 and the air conditioning assembly 20 do not interfere with each other, facilitating the independent operation of the air conditioning fan.

[0073] Optionally, the second fan 303 and the water collection component 304 are arranged sequentially along the airflow direction of the lower space 103. This allows the second fan 303 to efficiently drive fresh air through the water collection component 304.

[0074] Optionally, the second fan 303 is a centrifugal fan. Centrifugal fans have the advantages of low cost and stable air output. They can ensure the normal air output of the air conditioning fan assembly 30 and reduce the cost of the air conditioning unit 1.

[0075] Optionally, the air outlet is provided with a louver 1061. The louver 1061 is used to adjust the air outlet direction so that the air conditioning fan assembly 30 has a larger air outlet range.

[0076] Optionally, such as Figure 17 As shown, the air conditioning unit 1 also includes a first damper 40. The first damper 40 is located at the fresh air inlet 104 and is used to control the opening and closing of the fresh air inlet 104.

[0077] In this embodiment, the first damper 40 makes the entry of fresh air controllable, and the user can choose to allow or disconnect the flow of fresh air into the air conditioning unit 1 according to their needs.

[0078] Optionally, such as Figure 17 and Figure 18 As shown, the housing 10 is also provided with a return air vent 105. The return air vent 105 is connected to the room, and the fan can drive the airflow to flow in through the return air vent 105, then flow through the water collection component 304 and then flow out from the air outlet.

[0079] In this embodiment, the return air vent 105 facilitates the flow of indoor air into the air conditioning unit 1. When the ambient temperature is high, the air conditioning fan assembly 30 can be controlled to draw air in through the return air vent 105. This ensures the normal operation of the air conditioning fan assembly 30 and maintains the temperature of the airflow flowing out of the air conditioning fan assembly 30.

[0080] In one specific embodiment, when the second fan 303 and the water collection component 304 are both located in the lower space 103, the fresh air inlet 104, the return air inlet 105 and the air outlet are all located in the housing 10 corresponding to the lower space 103.

[0081] In this embodiment, the air conditioning fan assembly 30 is provided with independent fresh air inlet 104, return air inlet 105 and air outlet, which can ensure the independent operation of the air conditioning fan assembly 30, reduce the airflow distance, and facilitate the individual adjustment of the air intake and exhaust of the air conditioning fan.

[0082] It should be noted that when the fresh air inlet 104, return air inlet 105, and air outlet are all located in the lower space 103, the upper space 102, corresponding to the housing 10, is also provided with a main air inlet and a main air outlet 107. The first fan 201 can drive airflow to flow in from the main air inlet, exchange heat with the heat exchanger 202, and then flow out from the main air outlet to meet the normal operation of the air conditioning component 20.

[0083] In another specific embodiment, the water collection component 304 is located in the upper space 102. When the air conditioning component 20 and the air conditioning fan component 30 share the first fan 201, the fresh air inlet 104, the return air inlet 105, and the air outlet are also located in the upper space 102. That is to say, the air conditioning component 20 and the air conditioning fan component 30 share the fresh air inlet 104, the return air inlet 105, and the air outlet, which can increase the air outlet area of ​​the air conditioning fan component 30.

[0084] Optionally, when only the air conditioning fan assembly 30 needs to be turned on, the heat exchanger 202 and / or the compressor can be shut down. The first fan 201 operates normally to save energy consumption of the air conditioning unit 1.

[0085] Optionally, the air conditioning unit 1 also includes a second damper 50. The second damper 50 is located at the return air inlet 105 and is used to control the opening and closing of the return air inlet 105.

[0086] In this embodiment, the second air damper 50 makes the opening and closing of the return air vent 105 controllable. Users can choose to let indoor airflow flow into the air conditioning fan assembly 30 from the return air vent 105 or let outdoor airflow flow into the air conditioning fan assembly 30 from the fresh air vent 104, according to their needs.

[0087] Optionally, when the air conditioning assembly includes a first fan 201 and a second fan 303, the air outlet includes a main air outlet 107 and an auxiliary air outlet 106. The main air outlet 107 is connected to both the air conditioning assembly 20 and the air conditioning fan assembly 30, and the auxiliary air outlet 106 is connected to the air conditioning fan assembly 30. The airflow from the air conditioning fan assembly 30 can flow to the main air outlet 107 and mix with the airflow from the air conditioning assembly 20 to form a uniform airflow before flowing out.

[0088] In this embodiment, the first fan 201 drives indoor airflow to flow in from the air inlet 1021 and out from the main air outlet 107, thereby achieving the temperature regulation function of the air conditioning unit 20. The fresh air inlet 104 connects the outside environment to the receiving cavity 101 and is also connected to the air conditioning fan assembly 30. The second fan 303 drives outside airflow to flow into the receiving cavity 101 from the fresh air inlet 104 and / or the return air inlet 105, then flows through the water collection component 304, exchanges heat with it, and flows to the main air outlet 107. Thus, the air outlets of the air conditioning unit 20 and the air conditioning fan assembly 30 mix at the main air outlet 107 to form a uniform airflow. This uniform airflow increases the outlet temperature of the air conditioning unit 1 and provides a gentler breeze, making the air from the air conditioning unit 1 cool but not cold. This prevents the air from the air conditioning unit 1 from blowing directly on the user, improving the user experience and preventing the user from suffering from air conditioning sickness.

[0089] In this embodiment, fresh air is driven into the receiving cavity 101 by the second fan 303 and mixed with the airflow from the air conditioning component 20 to form uniform airflow. This gives the air conditioning unit 1 an active uniform airflow function, improving the user experience. The fresh air flows through the water collection component 304, which collects water from the water tank 301, thus increasing the moisture content of the fresh air flowing through it. When the air conditioning fan component 30 mixes with the airflow from the air conditioning component 20, it also increases the humidity of the outflowing uniform airflow. This prevents the indoor air from becoming dry due to prolonged air conditioning operation, thereby improving the user experience.

[0090] The principle by which the air conditioning fan assembly 30 and the air conditioning assembly 20 create uniform airflow is air jet technology. Air jet technology includes the principle of jet entrainment. The principle of jet entrainment is that when a fluid flows at high speed, because its speed is faster than the surrounding fluid, it carries the surrounding fluid along with it. The change in pressure around the high-speed fluid has a guiding effect on the surrounding fluid.

[0091] Optionally, the air conditioning unit 1 further includes a partition 108. The partition 108 is disposed within the receiving cavity 101, dividing the receiving cavity 101 into an upper space 102 and a lower space 103. The main air outlet 107 is disposed at the housing 10 corresponding to the upper space 102. The partition 108 is provided with a vent 1081 so that the airflow from the air conditioning fan assembly 30 can flow through the vent 1081 to the main air outlet 107.

[0092] In this embodiment, the partition 108 divides the receiving cavity 101 into an upper space 102 and a lower space 103, where the air conditioning assembly 20 and the air conditioning fan assembly 30 are respectively placed. This avoids airflow turbulence in the air conditioning assembly 20 and the air conditioning fan assembly 30 when the first fan 201 and / or the second fan 303 are operating. The arrangement of the vent 1081 ensures that the airflow from the air conditioning fan assembly 30 can only flow through the vent 1081 to the main air outlet 107 to form a uniform airflow. This facilitates the stability of the uniform airflow formed at the main air outlet 107.

[0093] Optionally, the air conditioning unit 1 also includes a first guide plate 109. The first guide plate 109 is movably covered at the vent 1081 to connect or disconnect the upper space 102 and the lower space 103. That is, the first guide plate 109 can control the connection or disconnection between the air conditioning fan assembly 30 and the main air outlet 17.

[0094] In this embodiment, the first guide plate 109 makes the connection or separation between the upper space 102 and the lower space 103 controllable. The user can control the connection or separation between the upper space 102 and the lower space 103 by controlling the first guide plate 109, thereby enabling the air conditioning unit 1 to turn on uniform airflow or not.

[0095] Optionally, the first guide plate 109 is a sealed guide plate to improve the relative independence of the upper space 102 and the lower space 103. This can prevent airflow between the two spaces.

[0096] Optionally, the air conditioning unit 1 includes a third drive device. The third drive device is driven to move the first guide plate 109 to open or close the vent 1081.

[0097] Specifically, the third drive unit includes a motor and a gear connected together, with the gear meshing with the first guide plate 109. The motor drives the gear to rotate, and the gear drives the first guide plate 109 to move, thereby opening or closing the vent 1081.

[0098] Optionally, the air conditioning unit 1 can be a cabinet air conditioner, a wall-mounted air conditioner, or a window air conditioner.

[0099] In the case of a cabinet-type air conditioner, the upper space 102 is located above the lower space 103. That is, the air conditioning component 20 is located in the upper part of the casing 10. The air conditioning fan component 30 is located in the lower part of the casing 10. In this way, the air conditioning fan component 30 makes full use of the space in the lower part of the cabinet-type air conditioner, increasing the structural compactness of the air conditioning unit 1.

[0100] Optionally, the vent 1081 is located at one end of the partition 108 near the main air outlet 107. This reduces the distance the airflow from the air conditioning fan assembly 30 travels to the main air outlet 107, thus reducing airflow loss.

[0101] The air conditioning unit 1 also includes a second guide plate 1061. The second guide plate 1061 is movably disposed at the auxiliary air outlet 106 and is used to control the opening or closing of the auxiliary air outlet 106.

[0102] In this embodiment, the auxiliary air outlet 106 allows the air conditioning fan assembly 30 to independently blow air into the room. That is, the air conditioning fan assembly 30 and the air conditioning assembly 20 can also operate independently. When the difference between the indoor temperature and the set temperature is small, the air conditioning fan assembly 30 can be controlled to operate independently to save energy in the air conditioning unit 1. When the difference between the indoor temperature and the set temperature is large, the air conditioning assembly 20 can be controlled to operate independently to achieve rapid heating and cooling of the room. When the indoor temperature reaches the preset temperature range, the air conditioning unit 1 can be controlled to activate the uniform airflow mode to enhance the user experience.

[0103] When the air conditioning unit 1 is in uniform airflow mode, the first guide plate 109 opens and the second guide plate 1061 closes. The auxiliary air outlet 106 closes, and the airflow from the air conditioning fan assembly 30 can only flow to the main air outlet 107. This increases the uniform airflow effect and prevents airflow leakage, which would affect the uniform airflow effect.

[0104] When only the air conditioning fan assembly 30 needs to operate, the first guide plate 109 is closed and the second guide plate 1061 is opened. In this way, the airflow from the air conditioning fan assembly 30 can only flow into the room through the auxiliary air outlet 106 to achieve the effect of regulating the indoor temperature.

[0105] When the air conditioning unit 20 and the air conditioning fan unit 30 share the first fan 201, when the air conditioning unit 20 is turned on, the first fan 201, heat exchanger 202, and compressor all operate. When the air conditioning unit 20 is turned off, the compressor and / or heat exchanger 202 are turned off. When the air conditioning fan unit 30 is turned on, the first fan 201 and drive unit 305 both operate. When the air conditioning fan unit 30 is turned off, the drive unit 305 is turned off to ensure that the water collection part 304 is free of water. When the first fan 201 is turned off, both the air conditioning fan unit 30 and the air conditioning unit 20 are turned off simultaneously.

[0106] With the air conditioning unit 20 having a first fan 201 and the air conditioning fan assembly 30 having a second fan 303, the air conditioning unit 20 and the air conditioning fan assembly 30 operate independently. When the air conditioning unit 20 is on, the first fan 201, heat exchanger 202, and compressor are all on. When the air conditioning unit 20 is off, the first fan 201 is off, and the compressor and / or heat exchanger 202 may be on or off. When the air conditioning fan assembly 30 is on, the second fan 303 and drive unit 305 are both on. When the air conditioning fan assembly 30 is off, the drive unit 305 is off. The second fan 303 may be on to drive fresh air flow or used as a fan, or it may be off.

[0107] Combination Figure 3 As shown, this disclosure provides a control method for an air conditioning unit, including:

[0108] S01. The air conditioning unit detects indoor air quality information.

[0109] S02. Based on the indoor air quality information, the air conditioning unit controls the operation of the first damper and the fan, so that the fresh air flows through the water accumulation part and then flows out through the air outlet.

[0110] In this embodiment, the air conditioning unit controls the opening and closing of the first damper based on indoor air quality information. This allows the first damper and fan to be opened to supply fresh air into the room when indoor air quality is poor. When indoor air quality is good, the first damper and fan are closed to maintain the indoor temperature.

[0111] Optionally, air quality information includes the concentration of carbon dioxide.

[0112] Combination Figure 4 As shown, this disclosure provides a control method for an air conditioning unit, including:

[0113] S11. The air conditioning unit detects the indoor carbon dioxide concentration.

[0114] S12. When the indoor carbon dioxide concentration is greater than or equal to the concentration threshold, the air conditioning unit controls the first damper and the fan to open.

[0115] In this embodiment, prolonged indoor time leads to an increase in indoor carbon dioxide concentration. Increased carbon dioxide concentration can cause drowsiness and fatigue in users. When the indoor carbon dioxide concentration is high, the first air damper and fan are activated, allowing the fan to drive fresh air into the room.

[0116] When the air conditioning fan assembly and the air conditioning assembly share the first fan, the fan in the above control method refers to the first fan.

[0117] When the air conditioning unit and the air conditioning fan unit are respectively equipped with a first fan and a second fan, the fan in the above method refers to the second fan.

[0118] Optionally, the concentration threshold can be 600ppm, 650ppm, 700ppm, 750ppm, etc.

[0119] Optionally, the air conditioning unit controls the operation of the drive unit based on indoor humidity and temperature. When indoor humidity is high, the drive unit is shut off to prevent the fresh air flowing through the water collection device from exchanging heat with it, thus avoiding increased humidity. When indoor humidity is suitable or low, the drive unit is activated to allow the fresh air flowing through it to exchange heat with the water collection device, thereby lowering the temperature of the fresh air and increasing its humidity.

[0120] Combination Figure 5 As shown in the embodiments of this disclosure, another control method for an air conditioning unit is provided, including:

[0121] S21. Detect indoor temperature.

[0122] S22. When the indoor temperature is higher than the set temperature, the air conditioning unit controls the air conditioning components to operate in cooling mode and detects the indoor temperature and humidity.

[0123] S23. Based on the indoor temperature and humidity, the air conditioning unit controls the operation of the air conditioning components and the air conditioning fan components.

[0124] In this embodiment, when the indoor temperature is high, the air conditioning unit operates in cooling mode. This lowers the indoor temperature. Simultaneously, based on the indoor temperature and humidity, the air conditioning unit controls the operation of both the air conditioning components and the air conditioning fan to maintain the indoor temperature and humidity within the desired range. This improves the user experience.

[0125] Combination Figure 6As shown, this disclosure provides a control method for an air conditioning unit, including:

[0126] S31. Detect indoor temperature.

[0127] S32. When the indoor temperature is higher than the set temperature, the air conditioning unit controls the air conditioning components to operate in cooling mode and detects the indoor temperature and humidity.

[0129] S34, The air conditioning unit controls the air conditioning components to turn on.

[0130] S35. Based on the indoor humidity, the air conditioning unit controls the opening and closing of the air conditioning components and the air conditioning fan components.

[0131] In this embodiment, when the indoor temperature exceeds the set temperature by a first threshold, that is, when the indoor temperature is significantly higher than the set temperature, the air conditioning unit controls the air conditioning components to turn on. The air conditioning components, when turned on, utilize the heat exchanger and the first fan to quickly cool the indoor environment, thus meeting the temperature control needs of the indoor users.

[0132] Combination Figure 7 As shown in the embodiments of this disclosure, another control method for an air conditioning unit is provided, including:

[0133] S41. Detect indoor temperature.

[0134] S42. When the indoor temperature is higher than the set temperature, the air conditioning unit controls the air conditioning components to operate in cooling mode and detects the indoor temperature and humidity.

[0135] S43. The air conditioning unit determines whether the difference between the indoor temperature and the set temperature is greater than the first threshold. If so, proceed to S44; otherwise, proceed to S45.

[0137] S45. The air conditioning unit determines whether the indoor humidity is greater than the first humidity threshold. If so, proceed to S46; otherwise, proceed to S47.

[0138] S46. The air conditioning unit controls the operation of the air conditioning components and controls the air conditioning fan components to shut down.

[0139] S47. When the indoor humidity is less than the second humidity threshold, the air conditioning unit controls the air conditioning components to shut down and controls the air conditioning fan components to turn on; wherein, the first humidity threshold is greater than the second humidity threshold.

[0140] In this embodiment, when the indoor temperature is not significantly different from the set temperature, the indoor temperature is considered comfortable. The air conditioning unit can control the operation of the air conditioning components and the air conditioning fan components based on the indoor humidity. The air conditioning components have a dehumidifying function, while the air conditioning fan components have a humidifying function. Through the coordinated operation of the air conditioning components and the air conditioning fan components, the indoor humidity can be regulated to meet the user's needs. Specifically, when the indoor humidity is greater than a first humidity threshold, it indicates that the indoor humidity is high. At this time, the air conditioning unit controls the air conditioning components to operate, while the air conditioning fan components are turned off. The air conditioning components dehumidify the room, and the air conditioning fan components do not humidify the room, thus reducing the indoor humidity. When the indoor humidity is less than a second humidity threshold, it indicates that the indoor humidity is low. The air conditioning unit controls the air conditioning components to turn off and controls the air conditioning fan components to operate. This increases the indoor temperature, ensuring that both the indoor temperature and humidity are within a suitable range, improving the user's experience.

[0141] Combination Figure 8 As shown, this disclosure provides a control method for an air conditioning unit, including:

[0150] S59. The air conditioning unit controls the air conditioning fan assembly to turn on, and controls the opening and closing of the air conditioning assembly according to the indoor temperature.

[0151] In this embodiment, if the indoor humidity is greater than the second threshold but less than the first threshold, it indicates that the indoor humidity is relatively suitable. The air conditioning unit then controls the air conditioning components and the air conditioning fan components based on the indoor temperature to ensure that the indoor temperature is as close as possible to the set temperature.

[0152] Combination Figure 9 As shown, this disclosure provides a control method for an air conditioning unit, including:

[0153] S51. Detect indoor temperature.

[0164] S62. The air conditioning unit detects the indoor carbon dioxide concentration.

[0165] S63. When the indoor carbon dioxide concentration is greater than or equal to the concentration threshold, the air conditioning unit controls the first damper and the fan to open.

[0166] In this embodiment, when the indoor humidity is greater than a second humidity threshold but less than a first humidity threshold, the indoor humidity is within a suitable range. The air conditioning unit controls the air conditioning fan assembly to operate, thereby maintaining the indoor humidity. When the indoor temperature is greater than a second threshold but less than a first threshold compared to the set temperature, it indicates that the indoor temperature is higher than the set temperature. At this time, the air conditioning unit controls the air conditioning components to turn on, thereby accelerating the reduction of the indoor temperature. When the difference between the indoor temperature and the set temperature is less than a second threshold but greater than a third threshold, it indicates that the indoor temperature is relatively close to the set temperature. The air conditioning unit can regulate the indoor temperature simply by controlling the air conditioning fan assembly, which not only regulates the indoor temperature but also saves energy.

[0167] Alternatively, the air conditioning unit can first detect the carbon dioxide concentration, and then detect the indoor temperature, combined with... Figure 10 This disclosure also provides another control method for an air conditioning unit, including:

[0168] S62. The air conditioning unit detects the indoor carbon dioxide concentration.

[0169] S63. When the indoor carbon dioxide concentration is greater than or equal to the concentration threshold, the air conditioning unit controls the first damper and the fan to open.

[0170] S51. Detect indoor temperature.

[0171] S52. When the indoor temperature is higher than the set temperature, the air conditioning unit controls the air conditioning components to operate in cooling mode and detects the indoor temperature and humidity.

[0176] S57. The air conditioning unit determines whether the indoor humidity is less than the second humidity threshold. If so, proceed to S58; otherwise, proceed to S59.

[0177] S58. The air conditioning unit controls the air conditioning components to shut down and controls the air conditioning fan components to operate; wherein, the first humidity threshold is greater than the second humidity threshold.

[0178] S59. The air conditioning unit controls the air conditioning fan assembly to turn on and determines whether the difference between the indoor temperature and the set temperature is greater than the second threshold. If so, execute S59; otherwise, execute S60.

[0179] S60, Air conditioning unit controls the air conditioning components to turn on.

[0180] S61. When the difference between the indoor temperature and the set temperature is less than the second threshold and greater than the third threshold, the air conditioning unit controls the air conditioning components to shut down; the first threshold is greater than the second threshold, and the second threshold is greater than the third threshold.

[0181] Optionally, the air conditioning unit can also simultaneously detect the indoor temperature and indoor carbon dioxide concentration. This application does not specifically limit the detection steps.

[0182] In one specific embodiment, the first threshold is 3℃, the second threshold is 1℃, and the third threshold is 0℃. When the indoor temperature is 3℃ higher than the set temperature, the user's temperature control needs cannot be met. The air conditioning unit can be controlled to turn on for rapid cooling. When the indoor temperature is greater than 1℃ but less than 3℃ from the set temperature, the indoor temperature is relatively suitable. When the indoor temperature is less than 1℃ but greater than 0℃ from the set temperature, the indoor temperature is close to the set temperature, and the indoor temperature is most suitable.

[0183] Optionally, the first threshold can also be 2.5℃, 3.5℃, 4℃, 5℃, etc. The second threshold can be 1.5℃, 2℃, etc., and the third threshold can be 0.5℃, 0.6℃, 0.7℃, etc. In practical applications, the corresponding first, second, and third thresholds can be set according to the user's heat resistance.

[0184] In one specific embodiment, the first humidity threshold is 45%, and the second humidity threshold is 60%. When the indoor humidity is greater than 60%, the indoor air humidity is high, and the air conditioning unit activates its air conditioning components to dehumidify. When the indoor humidity is less than 45%, the indoor air humidity is low, and the air conditioning unit activates its air conditioning fan components to humidify. When the indoor humidity is between 45% and 60%, the indoor humidity is considered suitable. The air conditioning unit can fine-tune the indoor temperature based on the indoor temperature control settings of the air conditioning unit and the air conditioning fan components.

[0185] Optionally, the first humidity threshold can also be 40%, 41%, 43%, 46%, 47%, etc. The second humidity threshold can also be 58%, 59%, 61%, 62%, etc.

[0186] The following example illustrates the operation of an air conditioning unit, using a first threshold of 3℃, a second threshold of 1℃, a third threshold of 0℃, a first humidity threshold of 45%, a second humidity threshold of 60%, and a concentration threshold of 700ppm:

[0187] When the air conditioning unit receives an operating command, it detects the indoor temperature. If the indoor temperature is higher than the set temperature, the air conditioning unit controls the air conditioning components to operate in cooling mode. If the difference between the indoor temperature and the set temperature is greater than 3°C, the air conditioning unit controls the air conditioning components to turn on. This accelerates the reduction of the indoor temperature to regulate it. If the difference is less than 3°C, the air conditioning unit detects the indoor humidity. If the indoor humidity is greater than 60%, the air conditioning unit controls the air conditioning components to turn on and the air conditioning fan to turn off. This utilizes the air conditioning components to reduce indoor humidity and avoids the air conditioning fan from humidifying. If the indoor humidity is less than 45%, the air conditioning unit controls the air conditioning fan to turn on and the air conditioning components to turn off. This utilizes the air conditioning fan to humidify the room and avoids the air conditioning unit from dehumidifying. If the indoor humidity is greater than 45% and less than 60%, indicating suitable indoor humidity, the air conditioning unit controls the air conditioning fan to operate to maintain indoor temperature and humidity. The air conditioning unit then detects the indoor temperature again and controls the air conditioning components to fine-tune the indoor temperature. This brings the indoor temperature closer to the set temperature, improving the user experience. When the difference between the indoor temperature and the set temperature is less than 3℃ but greater than 1℃, the air conditioning unit controls the air conditioning components to turn on to accelerate the cooling of the indoor temperature. When the difference between the indoor temperature and the set temperature is greater than 0℃ but less than 1℃, the air conditioning unit controls the air conditioning components to turn off, keeping only the air conditioning fan on. This not only maintains the indoor temperature but also reduces the energy consumption of the air conditioning unit. After the temperature and humidity are adjusted to a suitable range, the air conditioning unit detects the indoor carbon dioxide concentration. When the carbon dioxide concentration is higher than 700ppm, the air conditioning unit controls the first damper and the fan to open. Fresh air enters the casing through the fresh air inlet. At the same time, the air conditioning unit controls the fan to work to drive fresh air into the room. It should be noted that when the fan is a second fan, the air conditioning fan may not necessarily be on when the second fan is working. The air conditioning fan will only turn on when both the second fan and the drive unit are working. If only the second fan or the drive unit is working, the air conditioning fan cannot be turned on. Therefore, when the first damper is open, the second fan works, but the drive unit may not be working. The drive unit needs to be controlled according to the indoor temperature and humidity conditions mentioned above.

[0188] Combination Figure 11 As shown, when the fan includes a first fan and a second fan, the air conditioning fan assembly includes a second fan, which can drive airflow through the water accumulation component and then flow to the main air outlet and / or auxiliary air outlet 106. This disclosure provides a control method for an air conditioning unit, including:

[0202] S64. When the air conditioning unit and the second fan are turned on at the same time, the air conditioning unit controls the first guide plate to open and controls the second guide plate to close.

[0203] In this embodiment, when the air conditioning unit and the air conditioning fan unit are turned on simultaneously, the air conditioning unit controls the first guide plate to open and the second guide plate to close. This ensures that the air from the air conditioning unit and the air conditioning fan unit forms a uniform airflow at the main air outlet, so that the air from the air conditioning unit is cool but not cold.

[0204] Optionally, the air conditioning unit can control the first guide plate and the second guide plate before or after detecting the indoor temperature, or before or after detecting the carbon dioxide concentration. Alternatively, all three can be performed simultaneously. The above embodiment is merely one optional embodiment of this application. That is, the order between the air conditioning unit controlling the opening and closing of the first guide plate and the air conditioning unit detecting the indoor temperature and carbon dioxide concentration is not specifically limited in this application.

[0205] Combination Figure 12 As shown in the embodiments of this disclosure, another control method for an air conditioning unit is provided, including:

[0206] S51. Detect indoor temperature.

[0207] S52. When the indoor temperature is higher than the set temperature, the air conditioning unit controls the air conditioning components to operate in cooling mode and detects the indoor temperature and humidity.

[0215] S60, Air conditioning unit controls the air conditioning components to turn on.

[0216] S61. When the difference between the indoor temperature and the set temperature is less than the second threshold and greater than the third threshold, the air conditioning unit controls the air conditioning components to shut down; the first threshold is greater than the second threshold, and the second threshold is greater than the third threshold.

[0217] S62. The air conditioning unit detects the indoor carbon dioxide concentration.

[0218] S63. When the indoor carbon dioxide concentration is greater than or equal to the concentration threshold, the air conditioning unit controls the first damper and the fan to open.

[0219] S71. When the air conditioning fan assembly is turned on, the air conditioning unit detects the air volume at the air outlet.

[0220] S72. Control the opening and closing of the first and second dampers according to the air volume of the air outlet.

[0221] In this embodiment, when the air conditioning fan assembly is operating, the air intake volume at the fresh air inlet may not be sufficient to meet the user's needs. The air conditioning unit can control the opening and closing of the first and second air dampers based on the air output volume at the outlet, so that the air output volume of the air conditioning unit can meet the user's needs.

[0222] When the air conditioning fan assembly discharges air through the auxiliary air outlet, the air conditioning unit detects the airflow volume at the auxiliary air outlet. By controlling the opening and closing of the first and second air dampers, the airflow volume at the auxiliary air outlet is ensured to meet the set airflow volume. When the air conditioning fan assembly discharges air through the main air outlet, the air conditioning unit detects the airflow volume at the main air outlet. By controlling the opening and closing of the first and second air dampers, the airflow volume at the main air outlet is ensured to meet the set airflow volume.

[0223] Optionally, the air conditioning unit can control the first and second dampers based on the air volume before or after detecting the indoor temperature, or before or after detecting the carbon dioxide concentration. Alternatively, all three can be performed simultaneously. The above embodiment is merely one optional embodiment in this application. That is, the order in which the air conditioning unit controls the opening and closing of the first and second dampers and detects the indoor temperature and carbon dioxide concentration is not specifically limited in this application.

[0224] Taking the air conditioning fan assembly discharging air through the auxiliary air outlet as an example, the control of the first and second air dampers of the air conditioning unit is explained as follows:

[0225] The auxiliary air outlet is set to deliver an air volume of 200 m³ / h, with a fresh air delivery volume of 40 m³ / h and a return air volume of 160 m³ / h. The air conditioning fan unit has two operating speeds (high and low) and one operating speed for fresh air. When only fresh air is on, the first air damper is open and the second air damper is closed (the air conditioning fan unit can be operated at its low speed simultaneously), and the auxiliary air outlet delivers an air volume of 40 m³ / h. When the air conditioning fan unit is operated at its high speed, the first air damper is closed and the second air damper is open, resulting in an air volume of 160 m³ / h. When both fresh air and the air conditioning fan are on their high speeds simultaneously, both the first and second air dampers are open, and the auxiliary air outlet delivers an air volume of 200 m³ / h.

This application does not make any specific limitation here.

[0263] Combination Figure 15 As shown in the embodiments of this disclosure, another control method for an air conditioning unit is also provided, including:

[0264] S81, Detect indoor humidity.

[0265] S82. When the indoor humidity is greater than the first humidity threshold, control the air conditioning unit to turn on and control the air conditioning fan unit to turn off.

[0266] S83. When the indoor humidity is less than the second humidity threshold, control the air conditioning unit to turn off and control the air conditioning fan unit to turn on; wherein the first humidity threshold is greater than the second humidity threshold.

[0267] In this embodiment, the air conditioning unit can control the opening and closing of the air conditioning components and the air conditioning fan components solely based on the indoor humidity.

[0268] In summary, the indoor temperature, humidity, and carbon dioxide concentration can be detected sequentially or simultaneously by the air conditioning unit. This application does not impose a specific order on the detection steps for the air conditioning unit.

[0269] Optionally, such as Figures 20 to 22 As shown, the air conditioning unit 1 also includes an air outlet duct 60, which is located on at least one side of the main air outlet 107. One end of the air outlet duct 60 is connected to the vent 1081, and the air outlet duct 60 extends along the length of the main air outlet 107. The air outlet duct 60 has multiple outlets 601, which are spaced apart sequentially along the length of the main air outlet 107. This allows the airflow from the air conditioning fan assembly 30 to flow through the outlets 601 to the main air outlet 107.

[0270] In this embodiment, the air outlet duct 60 is provided with multiple outlets 601, and the air outlet duct 60 extends along the length direction of the main air outlet 107. Thus, the heat-exchanged fresh air flowing out of the air conditioning unit 1 flows into the air outlet duct 60 through the vent 1081, and the air outlet duct 60 can guide the heat-exchanged fresh air flowing out of the air conditioning unit 1 to the main air outlet 107. The multiple outlets 601 are arranged sequentially at intervals along the length direction of the main air outlet 107. That is, the multiple outlets 601 are arranged sequentially at intervals along the extension direction of the air outlet duct 60. This increases the mixing area between the heat-exchanged fresh air flowing out of the air outlet duct 60 and the airflow flowing out of the air conditioning component 20, thereby improving the airflow uniformity.

[0271] The air outlet duct 60 is located on at least one side of the main air outlet 107 to facilitate the airflow from the air conditioning unit 1 and the uniform airflow effect of the air conditioning unit 1.

[0272] Optionally, the length of the air outlet duct 60 is matched with that of the main air outlet 107, meaning that the lengths of the air outlet duct 60 and the main air outlet 107 are the same or similar. This increases the mixing area of ​​the airflow from the air conditioning fan assembly 30 and the airflow from the air conditioning assembly 20, further enhancing the uniform airflow effect.

[0273] Specifically, the air outlet duct 60 can be located on one side of the main air outlet 107 or on both sides of the main air outlet 107. Alternatively, when there are multiple main air outlets 107, the air outlet duct 60 can be located between two adjacent main air outlets 107 to further enhance the uniform airflow effect.

[0274] When the air conditioning unit 1 is a cabinet air conditioner, the length direction of the main air outlet 107 can be the height direction. That is to say, the main air outlet 107 extends in the vertical direction. In this way, the air outlet duct 60 also extends in the height direction of the main air outlet 107 to increase the mixing area with the main air outlet 107.

[0275] Optionally, the extension direction of each outlet 601 is at an angle to the extension direction of the main air outlet 107, so as to achieve the mixing of the airflow from the air conditioning fan assembly 30 and the airflow from the air conditioning assembly 20.

[0276] In this embodiment, the extension direction of each outlet 601 forms an angle with the extension direction of the main air outlet 107. In this way, the fresh air flowing out of the outlet 601 of the air outlet duct 60 can disperse the airflow flowing out of the air conditioning component 20 and increase the mixing effect with the main air outlet 107, thereby increasing the uniform airflow effect.

[0277] Optionally, the main air outlet 107 is equipped with an air outlet vane. The air outlet vane can adjust the air outlet direction of the main air outlet 107, thereby increasing the air outlet range of the air conditioning unit 1.

[0278] Optionally, the air outlet duct 60 can rotate relative to the housing 10. This ensures that when the air outlet direction of the main air outlet 107 changes, the outlet 601 of the air outlet duct 60 still has an angle with the air outlet direction of the main air outlet 107.

[0279] Optionally, the air conditioning unit 1 further includes a first drive device. The first drive device is driven to rotate the air outlet duct 60, thereby adjusting the air outlet direction of the air outlet duct 60.

[0280] Optionally, the air conditioning unit 1 further includes an inlet water pipe 308 and an outlet water pipe 307. The inlet water pipe 308 connects the heat exchanger 202 and the water tank 301 to guide the condensate generated by the heat exchanger 202 into the water tank 301. The outlet water pipe 307 connects the water tank 301 and the water collection device 304 to guide the water in the water tank 301 to the water collection device 304. The inlet water pipe 308 and the outlet water pipe 307 are in contact or connected to each other so that the water in the inlet water pipe 308 can exchange heat with the water in the outlet water pipe 307.

[0281] In this optional embodiment, the inlet pipe 308 connects the heat exchanger 202 and the water tank 301, so the temperature of the water in the inlet pipe 308 is close to the temperature of the heat exchanger 202. The outlet pipe 307 connects the water tank 301 and the water collection component 304. Therefore, the temperature of the outlet pipe 307 is close to the temperature of the water in the water tank 301. When the condensate is stored in the water tank 301 for a long time, the water in the water tank 301 continuously exchanges heat with the external environment. The temperature of the water in the water tank 301 is close to room temperature, which also makes the temperature of the water in the outlet pipe 307 close to room temperature. The inlet pipe 308 and the outlet pipe 307 are connected or in contact, and the inlet pipe 308 and the outlet pipe 307 can exchange heat, so that the water in the outlet pipe 307 can approach the temperature of the heat exchanger 202 after exchanging heat with the inlet pipe 308. With this configuration, when the water from the outlet pipe 307 flows to the water collection component 304, the temperature of the water collection component 304 is close to the temperature of the heat exchanger 202. The temperature of the airflow driven by the fan after passing through the water collection component 304 is close to the temperature of the airflow passing through the heat exchanger 202, which saves energy consumption for the air conditioner. At the same time, it ensures that the temperature of the airflow exiting the air conditioning unit 1 reaches the user-set temperature, without affecting the user's temperature control experience, thus improving the user experience.

[0282] Optionally, the air conditioning unit 1 also includes a second heat exchanger 309. The inlet water pipe 308 and the outlet water pipe 307 are connected through the second heat exchanger 309, and the inlet water pipe 308 and the outlet water pipe 307 can exchange heat within the second heat exchanger 309.

[0283] In this optional embodiment, the second heat exchanger 309 is used to connect the inlet water pipe 308 and the outlet water pipe 307. The inlet water pipe 308 and the outlet water pipe 307 can achieve better heat exchange through the second heat exchanger 309, avoiding energy loss.

[0284] Optionally, the second heat exchanger 309 is a plate heat exchanger.

[0285] Plate heat exchangers consist of a series of metal plates with a specific corrugated shape stacked together. Thin rectangular channels are formed between the plates, allowing heat exchange to occur. Plate heat exchangers offer high heat exchange efficiency and low heat loss. They are also compact, lightweight, and require little floor space.

[0286] Optionally, the second fan 303 and the water collection component 304 are arranged sequentially along the airflow direction of the lower space 103. This facilitates the second fan 303 to efficiently drive fresh air through the water collection component 304.

[0287] Optionally, the water tank 301 is detachably connected to the housing 10.

[0288] In this optional embodiment, the water tank 301 is detachably connected to the housing 10. This facilitates the installation, disassembly, and maintenance of the water tank 301. Furthermore, when the air conditioning unit 20 is not operating (i.e., the heat exchanger 202 is not producing condensate), the water tank 301 can be disassembled and water manually added to ensure sufficient water in the tank. This allows the air conditioning fan assembly 30 to operate normally, enabling the air conditioning unit 1 to achieve energy-saving humidification.

[0289] In this embodiment, the air conditioning unit 1 functions as both an air conditioner and an air cooler. Users do not need to install an additional air cooler, thus addressing their needs for energy saving, air purification, and dual temperature and humidity control. This improves room space utilization, allowing for more complete electrical functions in small apartments and enhancing the user's smart home experience. Furthermore, when both the air conditioner and air cooler are operating, the air cooler can fully utilize condensate water to achieve dual temperature and humidity control, solving the problem of excessive dryness in the room after prolonged air conditioning. Simultaneously, the condensate water temperature is lower than the outlet temperature of a regular air cooler, resulting in lower power consumption, environmental friendliness, and health benefits, making it highly practical.

[0290] Optionally, the water tank 301 also includes a water tank body 3011 and a handle 3012. The handle 3012 is provided on the water tank body 3011 and is used to push and pull the water tank 301.

[0291] In this optional embodiment, the handle 3012 is used to pull the water tank body 3011. This facilitates pulling the water tank 301 out of the housing 10 to add water to the water tank 301. It also facilitates pushing the water tank 301 back into the housing 10 after water has been added.

[0292] Optionally, the water tank 301 is provided with an overflow port 3014, which is connected to the outside through an overflow pipe 3013.

[0293] In this optional embodiment, when the amount of condensate is large, the excess condensate in the water tank 301 can flow to the outside through the overflow port 3014 and the overflow pipe 3013.

[0294] Specifically, the overflow pipe 3013 is connected to the condensate drain pipe of the air conditioner. Excess condensate in the water tank 301 can be discharged through the condensate drain pipe of the air conditioner, eliminating the need for an additional drainage pipe. This makes the combination of the air conditioning assembly 20 and the air conditioning fan assembly 30 more compact and efficient.

[0295] Optionally, the air conditioning unit 1 also includes a water washing module located inside the water tank 301. A fan drives airflow through the water tank 301 and then out of the receiving cavity 101. The water washing module is used to purify the airflow flowing into the water tank 301.

[0296] In this optional embodiment, the water tank 301 is used to collect the condensate produced by the heat exchanger 202, enabling the recycling and reuse of the condensate produced by the air conditioning unit 20. The water tank 301 is equipped with a water washing module, which purifies the airflow flowing through it. The purified airflow exits the water tank 301, then flows out of the receiving cavity and into the room. Through the cooperation of the water tank 301 and the water washing module, not only is the airflow from the air conditioning unit 1 able to increase indoor humidity, but it also purifies the air. This ensures air cleanliness and improves the user experience.

[0297] The water-washing module can thoroughly purify the airflow entering through the fresh air inlet 104, removing impurities and fine particles from the fresh air. This improves the quality of the airflow entering the room and protects the health of users.

[0298] Optionally, the water washing module includes a rotating shaft, multiple blades, and a fourth drive device. The multiple blades are arranged sequentially at intervals along the circumference of the rotating shaft. The fourth drive device is connected to the rotating shaft and can drive the rotating shaft to rotate, thereby causing the multiple blades to rotate. When the blades rotate, a water film is formed between every two adjacent blades. The water film can purify impurities in the airflow flowing through it. The water film enables the purification and / or humidification of the airflow.

[0299] Optionally, the air conditioning unit 1 also includes an air inlet grille, which is located at the fresh air inlet 104 and / or the return air inlet 105. The air conditioning unit 1 also includes a primary filter, which is located at the air inlet grille.

[0300] In this embodiment, the primary filter can prevent dust or impurities from entering the receiving cavity, thereby preventing the water accumulation component 304 from being contaminated and protecting the water accumulation component 304.

[0301] Combination Figure 16 As shown, this embodiment of the disclosure provides an air conditioning unit, including a processor 100 and a memory 101. Optionally, the device may further include a communication interface 102 and a bus 103. The processor 100, communication interface 102, and memory 101 can communicate with each other via the bus 103. The communication interface 102 can be used for information transmission.
