[0007] In some embodiments, determining the operating mode of the air conditioner includes: determining the operating mode according to the wind resistance of an evaporator of the air conditioner.

[0008] In some embodiments, the operating mode is determined based on the wind resistance of the evaporator of the air conditioner, including: if the wind resistance is greater than a first preset wind resistance, determining that the operating mode is a dehumidification mode; if the wind resistance is less than a second preset wind resistance, determining that the operating mode is a humidification mode; wherein the first preset wind resistance is greater than the second preset wind resistance.

[0009] Optionally, determining the operating mode according to the wind resistance of the evaporator of the air conditioner includes: controlling the evaporator to frost first and then defrost to perform self-cleaning of the evaporator; controlling the evaporator to frost again; when the evaporator is in the re-frosting state, obtaining the wind resistance of the evaporator; determining the indoor humidity according to the wind resistance of the evaporator; and determining the operating mode according to the indoor humidity.

[0010] In some embodiments, after determining the operating mode, the control method also includes: obtaining the current outdoor ambient humidity; when the air conditioner is operating in a humidification mode, switching between internal circulation humidification and external circulation humidification according to the current outdoor ambient humidity; when the air conditioner is operating in a dehumidification mode, switching between internal circulation dehumidification and external circulation dehumidification according to the current outdoor ambient humidity.

[0011] In some embodiments, when the air conditioner is running in a humidification mode, switching between internal circulation humidification and external circulation humidification is performed according to the current outdoor ambient humidity, including: when the air conditioner is running in a humidification mode, if the current outdoor ambient humidity is greater than a first preset humidity, the air conditioner is controlled to perform external circulation humidification in the current humidity adjustment mode; if the current outdoor ambient humidity is less than or equal to the first preset humidity, the air conditioner is controlled to perform internal circulation humidification in the current humidity adjustment mode, wherein the humidification mode includes internal circulation humidification and external circulation humidification.

[0012] In some embodiments, when the air conditioner is running in dehumidification mode, switching between internal circulation dehumidification and external circulation dehumidification is performed according to the current outdoor ambient humidity, including: when the air conditioner is running in dehumidification mode, if the current outdoor ambient humidity is greater than a second preset humidity, the air conditioner is controlled to perform internal circulation dehumidification in the current humidity adjustment mode; if the current outdoor ambient humidity is less than or equal to the second preset humidity, the air conditioner is controlled to perform external circulation dehumidification in the current humidity adjustment mode, wherein the dehumidification mode includes internal circulation dehumidification and external circulation dehumidification.

[0013] The technical solution of the second aspect of the present invention provides a control device for an air conditioner, comprising: a determination module, configured to determine the operating mode of the air conditioner, the operating mode including a humidification mode and a dehumidification mode; a humidification speed adjustment module, configured to, when the air conditioner is operating in the humidification mode, if the indoor humidity is greater than a first threshold, reduce the speed of the hygroscopic fan of the air conditioner; if the indoor humidity is less than the first threshold, increase the speed of the hygroscopic fan; and / or a dehumidification speed adjustment module, configured to, when the air conditioner is operating in the dehumidification mode, if the indoor humidity is greater than a second threshold, increase the speed of the hygroscopic fan of the air conditioner; if the indoor humidity is less than the second threshold, reduce the speed of the hygroscopic fan.

[0014] The technical solution of the third aspect of the present invention provides a control device for an air conditioner, comprising a processor and a memory storing program instructions, wherein the processor is configured to execute a control method for an air conditioner as described in any one of the above embodiments when executing the program instructions.

[0015] The technical solution of the fourth aspect of the present invention provides an air conditioner, comprising a control device for an air conditioner as described in any one of the above embodiments.

[0016] The control method and control device for an air conditioner and the air conditioner provided by the embodiments of the present disclosure can achieve the following technical effects:

[0017] In the humidification mode, the indoor humidity is less than the first threshold value, which means that the lower the indoor humidity, the higher the speed of the hygroscopic fan. The hygroscopic fan can drive more unheated air to flow through the hygroscopic material per unit time. The hygroscopic material absorbs more moisture from the unheated air, so that the heated air can absorb more moisture and discharge it into the room when flowing through the hygroscopic material, thereby achieving rapid humidification; when the indoor humidity is greater than the first threshold value, it means that the indoor humidity is higher and it is easier to humidify. The speed of the hygroscopic fan is reduced. The hygroscopic fan can drive a smaller amount of unheated air to flow through the hygroscopic material per unit time. The hygroscopic material absorbs less moisture from the unheated air, so that the heated air can absorb less moisture and discharge it into the room when flowing through the hygroscopic material. Because the indoor humidity is higher, the dehumidification time will not be excessively extended, precise humidification will be achieved, and the humidification energy consumption of the air conditioner can be reduced.

[0018] In dehumidification mode, if the indoor humidity is greater than the second threshold value, it means that the indoor humidity is relatively high, and the rotation speed of the hygroscopic fan increases. The hygroscopic fan can drive more unheated air to flow through the hygroscopic material per unit time. The hygroscopic material absorbs more moisture from the unheated air, so that the heated air can absorb more moisture when flowing through the hygroscopic material and discharge it to the outdoors, thereby achieving rapid dehumidification; if the indoor humidity is less than the second threshold value, it means that the lower the indoor humidity, the easier it is to dehumidify, and the rotation speed of the hygroscopic fan decreases. The hygroscopic fan can drive a smaller amount of unheated air to flow through the hygroscopic material per unit time, and the hygroscopic material absorbs a smaller amount of moisture from the unheated air, so that the heated air can absorb a smaller amount of moisture when flowing through the hygroscopic material and discharge it to the outdoors, thereby achieving rapid dehumidification.

[0019] In humidification mode and dehumidification mode, the speed of the moisture absorbing fan is determined according to the relationship between the indoor humidity and the first threshold, and the indoor humidity and the second threshold, respectively, which can reduce the humidity control energy consumption of the air conditioner while meeting the user's requirements for the humidity control speed.

[0037] Combination Figure 5-11As shown, in some embodiments, an air conditioner includes: a housing 100, a humidity control rotary disk 200, and a first partition 300. The housing 100 defines a cavity 110, and one end of the cavity 110 has an opening; the humidity control rotary disk 200 is rotatably disposed in the cavity 110, and a flow cavity is defined between the upper end surface of the humidity control rotary disk 200 and the inner wall of the cavity 110, and air flow can pass through the humidity control rotary disk 200 in a vertical direction, and the lower end surface of the humidity control rotary disk 200 is located at the opening; the first partition 300 is rotatably disposed in the flow cavity, and divides the flow cavity into a first chamber 112 and a second chamber 113.

[0038] With the air conditioner provided by the embodiment of the present disclosure, when the airflow at room temperature flows through the humidity control rotary disk 200, the moisture in the airflow will be absorbed, and when the heated airflow flows through the humidity control rotary disk 200 that absorbs moisture, the moisture in the humidity control rotary disk 200 will be released into the airflow. By utilizing this characteristic of the humidity control rotary disk 200, the humidity control rotary disk 200 is driven to rotate continuously below the first chamber 112 and the second chamber 113, and one of the airflow or the heated airflow passes through the humidity control rotary disk 200 located below the first chamber 112 to enter the first chamber 112, and then passes through the humidity control rotary disk 200 located below the first chamber 112 again to flow out, and the other passes through the humidity control rotary disk 200 located below the second chamber 113 to enter the second chamber 113, and then passes through the humidity control rotary disk 200 located below the second chamber 113 again to flow out The humidity regulating turntable 200 on the other side can better absorb the moisture in the airflow, or better release the absorbed moisture into the heated airflow, so as to better and continuously humidify or dehumidify the indoor room, and can also drive the first baffle 300 to rotate and switch the airflow flow path according to the outdoor air quality, so that the indoor airflow can be exchanged with the outdoor airflow during humidification or dehumidification, or not, and then the indoor airflow can be exchanged with the outdoor airflow when there is a need for indoor ventilation, and the indoor airflow can not be exchanged with the outdoor airflow when the outdoor air quality is poor and there is no need for ventilation, so as to avoid the outdoor polluted air from entering the room, selectively utilize the outdoor airflow, reduce the dependence on the outdoor environment, improve the stability of humidity regulation, and maintain the quality of indoor air.

[0039] Optionally, a heating device 310 is provided in the first chamber 112 and / or the second chamber 113. In this way, the airflow flowing through the first chamber 112 and / or the second chamber 113 can be heated, so that the airflow flowing out of the first chamber 112 and / or the second chamber 113 can take away the moisture in the humidity control rotary disk 200 located below the first chamber 112 and / or the second chamber 113, thereby achieving the effect of humidification or dehumidification, and better continuously humidifying or dehumidifying the room.

[0040] A hygroscopic material is arranged in the humidity regulating turntable. When the air flow passes through the humidity regulating turntable, the moisture in the air flow is absorbed by the hygroscopic material, or the absorbed moisture in the hygroscopic material is released into the air flow, thereby better humidifying or dehumidifying the room.

[0041] Optionally, a heating device 310 is provided in both the first chamber 112 and the second chamber 113. In this way, the indoor environment can be dehumidified or humidified by controlling the opening or closing of the heating devices 310 in the first chamber 112 and the second chamber 113, regardless of whether the indoor environment is in the internal circulation or the external circulation, and the two heating devices 310 are on the same horizontal line and are arranged crosswise with the first partition 300, so that the airflow flowing through the first chamber 112 or the second chamber 113 can be better heated, thereby better humidifying or dehumidifying the indoor environment. For example, when the indoor environment is in internal circulation, the first chamber 112 is connected to the indoor environment, and the second chamber 113 is connected to the outdoor environment. By controlling the heating device 310 in the first chamber 112 to be turned off and the heating device 310 in the second chamber 113 to be turned on, the moisture in the airflow flowing through the first chamber 112 is absorbed by the hygroscopic material in the humidity control rotary disk 200 located below the first chamber 112, and the airflow flowing through the second chamber 113 is heated, so that the heated airflow takes away the moisture in the hygroscopic material in the humidity control rotary disk 200 located below the second chamber 113, thereby dehumidifying the indoor environment. Alternatively, the heating device 310 in the first chamber 112 can be turned on and the heating device 310 in the second chamber 113 can be turned off, so that the moisture in the airflow flowing through the second chamber 113 is absorbed by the humidity control rotary disk 200 located below the second chamber 113, and the airflow flowing through the first chamber 112 is heated, and the heated airflow takes away the moisture in the humidity control rotary disk 200 located below the first chamber 112. The first chamber 112 is connected to the outdoor environment, and the second chamber 113 is also connected to the outdoor environment. By controlling the heating device 310 in the first chamber 112 to be turned off and the heating device 310 in the second chamber 113 to be turned on, the airflow from the indoor to the outdoor passes through the first chamber 112, and the moisture in the airflow is absorbed by the humidity control rotary disk 200. The airflow from the outdoor to the indoor passes through the second chamber 113 and is heated. The heated airflow takes away the moisture in the humidity control rotary disk 200 and is discharged to the indoor, which plays a role in humidifying the indoor environment. The heating device 310 in the first chamber 112 can also be controlled to be turned on, and the heating device 310 in the second chamber 113 can be turned off. The airflow from the outdoor to the indoor passes through the moisture in the second chamber 113 and is absorbed by the humidity control rotary disk 200. The airflow from the indoor to the outdoor passes through the first chamber 112 and is heated. The heated airflow takes away the moisture in the humidity control rotary disk 200 and is discharged to the outdoor, which plays a role in dehumidifying the indoor environment.

[0042] For the convenience of description, the heating device located in the first chamber is named as the first heating device, and the heating device located in the second chamber is named as the second heating device. Either the first heating device or the second heating device is turned on. The air conditioner further includes a fan, and the fan includes a first fan and a second fan. The first fan corresponds to the first heating device, and the air driven by the first fan can flow through the first heating device. The second fan corresponds to the second heating device, and the air driven by the second fan can flow through the second heating device. When the first heating device is turned on and the second heating device is turned off, the first fan is a regeneration fan, and the second fan is a regeneration fan. It is a hygroscopic fan. At this time, the air passing through the first heating device flows through the hygroscopic material, absorbs the moisture in the hygroscopic material, and realizes the regeneration of the hygroscopic material. The air passing through the second heating device flows through the hygroscopic material and absorbs the moisture in the hygroscopic material to realize humidification of the air; when the first heating device is turned off and the second heating device is turned on, the first fan is a hygroscopic fan, and the second fan is a regeneration fan. At this time, the air passing through the second heating device flows through the hygroscopic material, absorbs the moisture in the hygroscopic material, and realizes the regeneration of the hygroscopic material. The air passing through the first heating device flows through the hygroscopic material and absorbs the moisture in the hygroscopic material to realize humidification of the air.

[0043] Optionally, the air conditioner includes a driving device, which is connected to the humidity control turntable and is used to drive the humidity control turntable to rotate, so that the humidity control turntable 200 located below the first chamber 112 and the second chamber 113 continuously rotates, and continuously absorbs and releases moisture during the rotation process, thereby better humidifying or dehumidifying the room.

[0044] In some optional embodiments, the air conditioner further comprises: a housing 700. The housing 700 defines an installation cavity inside, the housing 100 is installed in the installation cavity, a partition plate 750 is provided in the housing, and the housing 100 and the partition plate 750 cooperate to separate the installation cavity into a first airflow cavity 710, a second airflow cavity 720, a third airflow cavity 730 and a fourth airflow cavity 740. In this way, during the process of humidifying or dehumidifying the indoor environment, the first partition 300 can be driven to rotate and switch the airflow path according to the outdoor air quality and / or the outdoor environmental humidity, and then switch the connection relationship between the first airflow chamber 710, the second airflow chamber 720, the third airflow chamber 730 and the fourth airflow chamber 740, so that the indoor airflow and the outdoor airflow can be exchanged or not exchanged during the humidification or dehumidification process, and then the indoor airflow and the outdoor airflow can be exchanged when there is a need for indoor ventilation, and the indoor airflow and the outdoor airflow will not be exchanged when the outdoor air quality is poor and there is no need for ventilation, so as to prevent outdoor polluted air from entering the room, selectively utilize outdoor airflow, reduce dependence on the outdoor environment, improve the stability of humidity regulation, and maintain the quality of indoor air.

[0045] Optionally, a first vent 751 is provided between the first airflow chamber 710 and the third airflow chamber 730, and a second vent 752 is provided between the second airflow chamber 720 and the fourth airflow chamber 740. In this way, when the internal circulation is conducted with indoors being connected to indoors and outdoors being connected to outdoors, and the outdoor environmental quality is high, the first airflow chamber 710 is communicated with the second airflow chamber 720, and the third airflow chamber 730 is communicated with the fourth airflow chamber 740. At this time, a small amount of outdoor air can enter the room through the first vent 751, and a small amount of indoor air can be discharged to the outside through the second vent 752, so as to conduct outdoor circulation of fresh air and improve the indoor air quality.

[0046] Optionally, the first vent 751 is disposed on the partition plate 750 between the first airflow cavity 710 and the third airflow cavity 730, and the second vent 752 is disposed on the partition plate 750 between the second airflow cavity 720 and the fourth airflow cavity 740, and a switch structure is disposed on both the first vent 751 and the second vent 752. In this way, the first vent 751 and the second vent 752 can be used to exchange fresh air between indoor and outdoor, improve the quality of indoor air, and the opening and closing of the first vent 751 and the second vent 752 can be controlled by the switch structure.

[0047] Optionally, the housing 100 is disposed in the middle of the installation cavity, so that the first airflow cavity 710, the second airflow cavity 720, the third airflow cavity 730 and the fourth airflow cavity 740 separated by the housing 100 are uniform in size and flow area, so that the airflow flows more smoothly.

[0048] Optionally, when the first baffle 300 is located at the first position, the first airflow chamber 710 is connected to the second airflow chamber 720, and the third airflow chamber 730 is connected to the fourth airflow chamber 740; when the first baffle 300 is located at the second position, the first airflow chamber 710 is connected to the third airflow chamber 730, and the second airflow chamber 720 is connected to the fourth airflow chamber 740. In this way, by switching the position of the first baffle 300, the connection relationship of the flow channel in the housing 700 can be switched, so that the outdoor is connected to the outdoor, the indoor is connected to the indoor, or the indoor is connected to the outdoor. While continuously humidifying or dehumidifying the indoor environment, the airflow channel can be switched according to the quality of the outdoor environment, thereby improving environmental adaptability.

[0049] Optionally, the housing 700 includes a first air inlet 701 and a first air outlet 702 connected to the outdoors, a second air inlet 703 and a second air outlet 704 connected to the indoors, the first air inlet 701 is connected to the first airflow cavity 710, the first air outlet 702 is connected to the second airflow cavity 720, the second air outlet 704 is connected to the third airflow cavity 730, and the second air inlet 703 is connected to the fourth airflow cavity 740. In this way, by switching the position of the first partition 300, the connection relationship of the flow channel in the housing 700 can be switched, and then the connection relationship between the indoor and outdoor can be switched. While continuously humidifying or dehumidifying the indoor environment, the airflow channel can be switched according to the quality of the outdoor environment, thereby improving environmental adaptability. For example, when the first partition 300 is in the first position, the outdoor air flow enters the first air flow cavity 710 through the first air inlet 701, then passes through the humidity controlling rotary disk 200 through the first air inlet end 230 on the lower end surface of the humidity controlling rotary disk 200 and enters the first chamber 112, then is blown out through the first air outlet end 240 and flows into the second air flow cavity 720, and finally is blown out to the outdoors through the first air outlet 702, completing a cycle of the outdoor air flow. The indoor air flow enters the fourth air flow cavity 740 through the second air inlet end 250 on the lower end surface of the humidity controlling rotary disk 200 and enters the second chamber 113, then is blown out through the second air outlet end 260 and flows into the third air flow cavity 730, and finally is blown out to the indoor through the second air outlet 704, completing a cycle of the indoor air flow. At this time, the outdoor is connected to the outdoor, and the indoor Connected with the indoor room; when the first partition 300 is in the second position, the outdoor air enters the first air flow cavity 710 through the first air inlet 701, and then passes through the humidity regulating turntable 200 through the first air inlet end 230 on the lower end surface of the humidity regulating turntable 200 to enter the first chamber 112, and then is blown out to the third air flow cavity 730 through the second air outlet end 260, and finally is blown out to the indoor room through the second air outlet 704, completing an outdoor to indoor cycle, the indoor air enters the fourth air flow cavity 740 through the second air inlet end 250 on the lower end surface of the humidity regulating turntable 200 to enter the second chamber 113, and then flows out to the second air flow cavity 720 through the first air outlet end 240, and finally is discharged to the outdoors through the first air outlet 702, completing an indoor to outdoor cycle, and at this time the indoor room is connected with the outdoors.

[0050] Fans 800 are provided at both the first air inlet 701 and the second air outlet 704. The fan located at the first air inlet is used to drive the air to flow between the first air inlet 701 and the portion of the humidity controlling disk corresponding to the first air inlet, and the fan located at the second air outlet 704 is used to drive the air to flow between the second air outlet 704 and the portion of the humidity controlling disk corresponding to the second air outlet 704.

[0051] In some examples, a condenser 760 is provided in the first airflow chamber 710 and / or the fourth airflow chamber 740. An evaporator 770 is provided in the second airflow chamber 720 and / or the third airflow chamber 730. The compressor, condenser and evaporator of the air conditioner are connected to form a refrigerant flow path to achieve normal cooling or heating of the air conditioner. The connection of the compressor, condenser and evaporator and the cooling and heating of the air conditioner are all existing technologies and will not be described in detail here.

The condenser 760 in the first air flow chamber 710 can heat the air flow flowing in from the outside, so that the air flow can more efficiently take away the moisture absorbed by the inside when passing through the humidity control rotary disk 200, and the evaporator 770 in the third air flow chamber 730 can perform secondary dehumidification on the dehumidified air flow flowing out of the humidity control rotary disk 200, further reducing the water content of the air flow flowing into the room; in the case of internal circulation humidification, the first air flow chamber 710 and the second air flow chamber 720 are connected to the outside, and the third air flow chamber 730 and the fourth air flow chamber 740 are connected to the indoor, and the condenser 760 in the fourth air flow chamber 740 can heat the air flow flowing in from the indoor, so that the air flow can more efficiently take away the moisture absorbed by the inside when passing through the humidity control rotary disk 200, further improving the humidification effect; in the case of external circulation dehumidification In the case of external circulation humidification, the first air flow chamber 710 and the third air flow chamber 730 are connected to the outdoors, the second air flow chamber 720 and the fourth air flow chamber 740 are connected to the outdoors, and the evaporator 770 in the third air flow chamber 730 can perform secondary dehumidification on the dehumidified outdoor air flow flowing out of the humidity control rotary disk 200, further reducing the water content of the air flow flowing into the room, and the condenser 760 in the fourth air flow chamber 740 can heat the air flow flowing out of the room, so that the air flow can more efficiently take away the moisture absorbed by the interior when passing through the humidity control rotary disk 200, further improving the dehumidification effect. In the case of external circulation humidification, the first air flow chamber 710 and the third air flow chamber 730 are connected to the outdoors, the second air flow chamber 720 and the fourth air flow chamber 740 are connected to the outdoors, and the condenser 760 in the first air flow chamber 710 can heat the air flow flowing in from the outdoors, so that the air flow can more efficiently take away the moisture absorbed by the interior when passing through the humidity control rotary disk 200, further improving the humidification effect.

[0053] In the humidification mode, the air conditioner can operate internal circulation humidification or external circulation humidification. Internal circulation humidification means that the outdoor air flows through the hygroscopic material and is discharged to the outside after absorbing moisture from the hygroscopic material, and the indoor air absorbs moisture from the hygroscopic material and flows into the room; the external circulation humidification mode means that the indoor air flows through the hygroscopic material and is discharged to the outside after absorbing moisture from the hygroscopic material, and the outdoor air absorbs moisture from the hygroscopic material and is discharged into the room.

[0054] In dehumidification mode, the air conditioner can operate internal circulation dehumidification or external circulation dehumidification. The external circulation dehumidification mode means that the outdoor air flows through the hygroscopic material and is discharged into the room after the hygroscopic material absorbs moisture, and the indoor air absorbs the moisture in the hygroscopic material and is discharged into the room; the internal circulation dehumidification means that the indoor air flows through the hygroscopic material and is discharged into the room after the hygroscopic material absorbs moisture, and the outdoor air absorbs the moisture in the hygroscopic material and is discharged into the room.

[0055] Combination Figure 1 As shown, the embodiment of the present disclosure provides a control method for an air conditioner, including steps S101 to S103.

[0056] In step S101, the air conditioner determines its operating mode, which includes a humidification mode and a dehumidification mode.

[0057] There are many ways to obtain indoor humidity, such as setting a humidity sensor indoors to obtain indoor humidity through the humidity sensor, or obtaining indoor humidity through weather forecasts.

[0058] Step S102, when the air conditioner is running in humidification mode, if the indoor humidity is greater than a first threshold, the air conditioner reduces the speed of the moisture absorption fan; if the indoor humidity is less than the first threshold, the speed of the moisture absorption fan is increased. And / or,

[0059] Step S103, when the air conditioner is running in dehumidification mode, if the indoor humidity is greater than the second threshold, the air conditioner increases the speed of the dehumidification fan; if the indoor humidity is less than the second threshold, the air conditioner reduces the speed of the dehumidification fan.

[0060] In the humidification mode, the indoor humidity is less than the first threshold value, which means that the lower the indoor humidity, the higher the speed of the hygroscopic fan. The hygroscopic fan can drive more unheated air to flow through the hygroscopic material per unit time. The hygroscopic material absorbs more moisture from the unheated air, so that the heated air can absorb more moisture and discharge it into the room when flowing through the hygroscopic material, thereby achieving rapid humidification; when the indoor humidity is greater than the first threshold value, it means that the indoor humidity is higher and it is easier to humidify. The speed of the hygroscopic fan is reduced. The hygroscopic fan can drive a smaller amount of unheated air to flow through the hygroscopic material per unit time. The hygroscopic material absorbs less moisture from the unheated air, so that the heated air can absorb less moisture and discharge it into the room when flowing through the hygroscopic material. Because the indoor humidity is higher, the dehumidification time will not be excessively extended, precise humidification will be achieved, and the humidification energy consumption of the air conditioner can be reduced.

[0061] In dehumidification mode, if the indoor humidity is greater than the second threshold value, it means that the indoor humidity is relatively high, and the rotation speed of the hygroscopic fan increases. The hygroscopic fan can drive more unheated air to flow through the hygroscopic material per unit time. The hygroscopic material absorbs more moisture from the unheated air, so that the heated air can absorb more moisture when flowing through the hygroscopic material and discharge it to the outdoors, thereby achieving rapid dehumidification; if the indoor humidity is less than the second threshold value, it means that the lower the indoor humidity, the easier it is to dehumidify, and the rotation speed of the hygroscopic fan decreases. The hygroscopic fan can drive a smaller amount of unheated air to flow through the hygroscopic material per unit time, and the hygroscopic material absorbs a smaller amount of moisture from the unheated air, so that the heated air can absorb a smaller amount of moisture when flowing through the hygroscopic material and discharge it to the outdoors, thereby achieving rapid dehumidification.

[0062] In humidification mode and dehumidification mode, the speed of the moisture absorbing fan is determined according to the relationship between the indoor humidity and the first threshold, and the indoor humidity and the second threshold, respectively, which can reduce the humidity control energy consumption of the air conditioner while meeting the user's requirements for the humidity control speed.

[0063] In step S101, the indoor humidity may also be represented by operating environment parameters of the air conditioner, which may be indoor condensed water volume, evaporator wind resistance, current air intake volume of the indoor unit, compressor frequency, and the like.

[0064] The higher the indoor humidity, the greater the indoor condensation water volume, evaporator wind resistance, and compressor frequency, and the smaller the current air intake of the indoor unit.

[0065] Taking the operating environment parameter as the current air intake volume of the indoor unit as an example, in the dehumidification mode, when the current air intake volume of the indoor unit is greater than the preset first air intake volume, the corresponding indoor humidity is less than the first threshold value; when the current air intake volume of the indoor unit is less than the preset first air intake volume, the corresponding indoor humidity is greater than the first threshold value. In the dehumidification mode, when the current air intake volume of the indoor unit is greater than the preset second air intake volume, the corresponding indoor humidity is less than the second threshold value; when the current air intake volume of the indoor unit is less than the preset second air intake volume, the corresponding indoor humidity is greater than the second threshold value.

[0066] In a specific embodiment, humidification mode: set the indoor unit air intake of a certain mode to h, obtain the current indoor unit air intake h1, h1<0.85h, the rotation speed of the dehumidification fan is reduced by 10%; 0.85h≤h1≤1.15h, keep the rotation speed of the dehumidification fan unchanged; 1.15h1<h, the rotation speed of the dehumidification fan is increased by 10%; re-determine after running for 20 minutes. The first threshold is an interval greater than or equal to 0.85h and less than or equal to 1.15h.

[0067] Dehumidification mode: A wind speed sensor is set at the air inlet of the air conditioner, and the air volume of a certain mode is set to h. The current air volume h1 is obtained. If h1 < 0.85h, the speed of the dehumidification fan is increased by 10%; if 0.85h ≤ h1 ≤ 1.15h, the speed of the dehumidification fan is kept unchanged; if 1.15h1 < h, the speed of the dehumidification fan is reduced by 10%; re-evaluate after running for 20 minutes. The second threshold is an interval greater than or equal to 0.85h and less than or equal to 1.15h.

[0068] In this specific embodiment, the first threshold value and the second threshold value are the same. It can be understood that the first threshold value and the second threshold value may also be different.

[0069] In a specific embodiment, a control method for an air conditioner includes:

[0070] Acquire indoor humidity and determine the operation mode of the air conditioner, the operation mode including humidification mode and dehumidification mode;

[0071] When the air conditioner is running in humidification mode, if the indoor humidity is greater than a first threshold, the rotation speed of the dehumidifying fan of the air conditioner is reduced; if the indoor humidity is less than the first threshold, the rotation speed of the dehumidifying fan is increased.

[0072] In another specific embodiment, a control method for an air conditioner includes:

[0073] Acquire indoor humidity and determine the operation mode of the air conditioner, the operation mode including humidification mode and dehumidification mode;

[0074] When the air conditioner is running in dehumidification mode, if the indoor humidity is greater than the second threshold, the rotation speed of the dehumidification fan of the air conditioner is increased; if the indoor humidity is less than the second threshold, the rotation speed of the dehumidification fan is reduced.

[0075] Optionally, determining the operation mode of the air conditioner in step S101 includes:

[0076] The operating mode is determined according to the wind resistance of the air conditioner's evaporator.

[0077] The higher the indoor humidity, the more air will stick, which will increase the wind resistance of the evaporator. The wind resistance of the evaporator refers to the resistance encountered by air when it flows through the evaporator after entering through the air inlet of the indoor unit. Therefore, the resistance of the evaporator can reflect the indoor humidity, and the operation mode can be determined based on the wind resistance of the evaporator.

[0078] Optionally, determining the operation mode according to the wind resistance of an evaporator of the air conditioner includes:

[0079] If the wind resistance is greater than the first preset wind resistance, determining that the operation mode is a dehumidification mode;

[0080] If the wind resistance is less than the second preset wind resistance, determining that the operation mode is the humidification mode;

[0081] Among them, the first preset wind resistance is greater than the second preset wind resistance.

[0082] By using the air conditioner's operating environment parameter, the wind resistance from the evaporator, to characterize the indoor humidity, the indoor humidity sensor can be omitted, the cost of the air conditioner can be reduced, and the malfunction of the air conditioner's humidity control function caused by damage to the humidity sensor can be avoided.

[0083] Optionally, determining the operation mode according to the wind resistance of an evaporator of the air conditioner includes:

[0084] Control the evaporator to frost first and then defrost to perform self-cleaning of the evaporator;

[0085] Control the evaporator to frost again;

[0086] When the evaporator is in a re-frosting state, obtain the wind resistance of the evaporator;

[0087] Determine the indoor humidity based on the corresponding relationship between the wind resistance of the evaporator and the indoor humidity;

[0088] The operating mode is determined according to the indoor humidity.

[0089] The air conditioner can be controlled to run the cooling mode first to achieve evaporator frosting, and then run the heating mode to achieve evaporator defrosting and self-cleaning of the evaporator. The dust on the evaporator fins can be cleaned to avoid the influence of different dust thickness on the fins on the wind resistance, that is, to avoid the influence of dust thickness on the evaporator wind resistance, so that the evaporator wind resistance is only affected by indoor humidity.

[0090] The air conditioner is controlled to run cooling again to achieve evaporator frosting. In the frosting state, the wind resistance of the evaporator is obtained.

[0091] Through experiments, the corresponding relationship between the wind resistance of the evaporator and the indoor humidity in the frosted state can be obtained. According to the corresponding relationship and the wind resistance of the evaporator, the indoor humidity can be obtained, or the wind resistance of the current evaporator in the re-frosted state can be compared with the wind resistance of the evaporator under the same temperature, different humidity and the same frosting time to determine the indoor humidity. If the indoor humidity is greater than the preset comfortable humidity range, the dehumidification mode is operated; if the indoor humidity is less than the preset comfortable humidity range, the humidification mode is operated; if the indoor humidity is equal to the preset comfortable humidity range, the air conditioner is controlled to stop the humidity adjustment work.

[0092] Optionally, after determining the operating mode, the control method further includes:

[0093] Get the current outdoor humidity;

[0094] When the air conditioner is running in humidification mode, the internal circulation humidification and external circulation humidification are switched according to the current outdoor ambient humidity;

[0095] When the air conditioner is running in dehumidification mode, the internal circulation dehumidification and external circulation dehumidification are switched according to the current outdoor ambient humidity.

[0096] In external circulation humidification and internal circulation humidification, the flow paths of indoor air and outdoor air are different. In external circulation humidification, the moisture in the indoor air is released into the hygroscopic material and discharged to the outside, and the outdoor air absorbs the moisture in the hygroscopic material and is discharged into the room; in internal circulation humidification, the moisture in the outdoor air is released into the hygroscopic material and discharged to the outside, and the indoor air absorbs the moisture in the hygroscopic material and is discharged into the room. Therefore, the humidification effects of external circulation humidification and internal circulation humidification are different for different current outdoor environmental humidity, so selecting the appropriate humidification mode (external circulation humidification or internal circulation humidification) according to the current outdoor environmental humidity can enhance the humidification effect.

[0097] In external circulation dehumidification and internal circulation dehumidification, the flow paths of indoor air and outdoor air are different. In external circulation dehumidification, the moisture in the outdoor air is released into the hygroscopic material and discharged into the room, and the indoor air absorbs the moisture in the hygroscopic material and is discharged into the outside; in internal circulation dehumidification, the moisture in the indoor air is released into the hygroscopic material and discharged into the room, and the outdoor air absorbs the moisture in the hygroscopic material and is discharged into the outside. Therefore, the dehumidification effect of external circulation dehumidification and internal circulation dehumidification is different for different current outdoor environmental humidity. Therefore, selecting the appropriate dehumidification mode (external circulation dehumidification or internal circulation dehumidification) according to the current outdoor environmental humidity can enhance the dehumidification effect.

[0098] Combination Figure 2 As shown, in one embodiment, the control method includes:

[0099] In step S201, the air conditioner determines an operation mode of the air conditioner, where the operation modes include a humidification mode and a dehumidification mode.

[0100] Step S202, when the air conditioner is running in humidification mode, if the indoor humidity is greater than the first threshold, the air conditioner reduces the speed of the dehumidifying fan; if the indoor humidity is less than the first threshold, the air conditioner increases the speed of the dehumidifying fan, and the air conditioner switches between internal circulation humidification and external circulation humidification according to the current outdoor ambient humidity.

[0101] Step S203, when the air conditioner is running in dehumidification mode, if the indoor humidity is greater than the second threshold, the air conditioner increases the speed of the dehumidification fan; if the indoor humidity is less than the second threshold, the air conditioner reduces the speed of the dehumidification fan, and the air conditioner switches between internal circulation dehumidification and external circulation dehumidification according to the current outdoor ambient humidity.

[0102] Optionally, when the air conditioner is running in a humidification mode, switching between internal circulation humidification and external circulation humidification is performed according to the current outdoor ambient humidity, including:

[0103] When the air conditioner is running in humidification mode, if the current outdoor environment humidity is greater than the first preset humidity, the air conditioner is controlled to perform external circulation humidification in the current humidity adjustment mode; if the current outdoor environment humidity is less than or equal to the first preset humidity, the air conditioner is controlled to perform internal circulation humidification in the current humidity adjustment mode, wherein the humidification mode includes internal circulation humidification and external circulation humidification.

[0104] When the current outdoor environmental humidity is greater than the first preset humidity, it means that the current outdoor environmental humidity is relatively high, and the outdoor air can be used to humidify the indoor environment. The indoor air flows through the hygroscopic material. After the hygroscopic material absorbs moisture in the indoor air, the air that has absorbed moisture flows out to the outdoors. The outdoor air absorbs the moisture in the hygroscopic material, so that the moisture content of the outdoor air is further increased, and the hygroscopic material can be regenerated. The outdoor air that has absorbed moisture flows into the indoor room to increase the indoor humidity as soon as possible; when the current outdoor environmental humidity is less than or equal to the first preset humidity, it means that the current outdoor environmental humidity is relatively low, and the effect of humidifying the indoor room with outdoor air is not obvious. Therefore, internal circulation humidification is selected, and the outdoor air flows through the hygroscopic material. After the hygroscopic material absorbs moisture in the outdoor air, the air that has absorbed moisture flows out to the outdoors. The indoor air absorbs the moisture in the hygroscopic material, so that the moisture content of the indoor air is further increased, and the hygroscopic material can be regenerated. The outdoor air that has absorbed moisture flows into the indoor room to increase the indoor humidity as soon as possible.

[0105] Optionally, when the air conditioner is running in a dehumidification mode, switching between internal circulation dehumidification and external circulation dehumidification is performed according to the current outdoor ambient humidity, including:

[0106] When the air conditioner is running in dehumidification mode, if the current outdoor environment humidity is greater than the second preset humidity, the air conditioner is controlled to perform internal circulation dehumidification in the current humidity adjustment mode; if the current outdoor environment humidity is less than or equal to the second preset humidity, the air conditioner is controlled to perform external circulation dehumidification in the current humidity adjustment mode, wherein the dehumidification mode includes internal circulation dehumidification and external circulation dehumidification.

[0107] When the current outdoor environmental humidity is greater than the second preset humidity, it means that the current outdoor environmental humidity is relatively high, and the outdoor air cannot be allowed to flow into the room to avoid increasing the indoor humidity. Therefore, internal circulation dehumidification is selected, and the indoor air flows through the hygroscopic material. After the hygroscopic material absorbs moisture in the indoor air, the air with absorbed moisture flows into the room to reduce the indoor air humidity. The outdoor air absorbs the moisture in the hygroscopic material to achieve the regeneration of the hygroscopic material, and the outdoor air after absorbing moisture flows into the outdoor room to avoid increasing the indoor humidity; when the current outdoor environmental humidity is less than or equal to the second preset humidity, it means that the current outdoor environmental humidity is relatively low, and the outdoor air can be dehumidified and flow into the room to reduce the indoor air humidity. Therefore, external circulation dehumidification is selected, and the outdoor air flows through the hygroscopic material. After the hygroscopic material absorbs moisture in the outdoor air, the air with absorbed moisture flows into the room to reduce the indoor humidity. The indoor air absorbs the moisture in the hygroscopic material to achieve the regeneration of the hygroscopic material, and the air after absorbing moisture flows into the outdoor room.

[0108] In a specific embodiment, the wind resistance at a certain time after the evaporator is self-cleaned is W, and the wind resistance W1 of the evaporator in the frosted state is monitored. If W1>1.2W, the dehumidification mode is turned on. When the current outdoor ambient humidity is>60%, the internal circulation dehumidification is turned on and the internal circulation dehumidification mode is entered; when the current outdoor relative humidity is ≤60%, the external circulation dehumidification is turned on; if W1<0.8W, the humidification mode is turned on. If the current outdoor relative humidity is>60%, the external circulation humidification is turned on and the external circulation humidification mode is entered; if the current outdoor relative humidity is ≤60%, the internal circulation humidification is turned on; 1.2W≤W1≤0.8W, the air conditioner operation state is maintained unchanged.
