[0036] Combination Figure 5-11 As 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] In the case of internal circulation dehumidification, 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. 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.

[0052] 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.

[0053] 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.

[0054] Combination Figure 1 As shown, the embodiment of the present disclosure provides a control method for an air conditioner, including steps S101 to S103.

[0055] Step S101: the air conditioner obtains the current power of the compressor.

[0056] The current power of the compressor can be collected in the cloud, or a detection device can be set up to detect the current power of the compressor, thereby obtaining the current power of the compressor.

[0057] Step S102: if the current power is greater than the first preset power, the air conditioner is controlled to run a dehumidification operation.

[0058] Step S103: if the current power is less than the second preset power, the air conditioner is controlled to perform a humidification operation; wherein the first preset power is greater than the second preset power.

[0059] The higher the air humidity, the greater the wind resistance of the fins, and the higher the operating power of the compressor. Therefore, when other parameters that affect the compressor power are the same, the current power (operating power) of the compressor can reflect the air humidity. Especially in the case of low-temperature heating, the higher the air humidity, the faster the condenser frosts, and the frequency of reverse cycle defrosting increases, which will increase the power of the compressor.

[0060] If the current power is greater than the first preset power, it means that the air humidity is high and the indoor humidity is high, and the dehumidification operation is run; if the current power is less than the second preset power, it means that the air humidity is low and the indoor humidity is low, and the humidification operation is run; if the current power is greater than or equal to the second preset power and less than or equal to the first preset power, it means that the air humidity is appropriate and the indoor humidity is appropriate, and the air conditioner is turned off.

[0061] It can be understood that the power of the compressor is related to the frequency of the compressor, and the frequency of the compressor can also be used to determine when to perform humidification or dehumidification operations. For example, if the current frequency is greater than the first preset frequency, it means that the air humidity is high and the indoor humidity is high, and the dehumidification operation is performed; if the current frequency is less than the second preset frequency, it means that the air humidity is low and the indoor humidity is low, and the humidification operation is performed; if the current frequency is greater than or equal to the second preset frequency and less than or equal to the first preset frequency, it means that the air humidity is appropriate and the indoor humidity is appropriate, and the air conditioner is turned off, wherein the first preset frequency is greater than the second preset frequency.

[0062] Optionally, if the air conditioner performs a dehumidification operation or a humidification operation, the control method further includes:

[0063] Obtaining the current outdoor environment relative humidity, and correcting the current outdoor environment relative humidity according to the current outdoor temperature and the current power to obtain the corrected current outdoor environment relative humidity;

[0064] The dehumidification operation mode or the humidification operation mode is determined according to the corrected current outdoor environment relative humidity. The dehumidification operation mode includes internal circulation dehumidification and external circulation dehumidification, and the humidification operation mode includes internal circulation humidification and external circulation humidification.

[0065] The current relative humidity of the outdoor environment can be obtained through a humidity sensor or through a weather forecast.

[0066] Relative humidity refers to the percentage of water vapor pressure in the air to the saturated water vapor pressure at the same temperature, reflecting the ratio of water content at a certain temperature to the saturated water content that can be tolerated. At different temperatures, the same relative humidity corresponds to different absolute humidity, so it is necessary to perform temperature correction on relative humidity to eliminate or reduce the impact of temperature on relative humidity.

[0067] The current power is used to correct the current outdoor environment relative humidity so that the current power can affect the corrected current outdoor environment relative humidity. The current power is related to the absolute value of the difference between the current outdoor temperature and the preset outdoor humidity, so that the absolute value of the difference between the current outdoor temperature and the preset outdoor humidity can affect the corrected current outdoor environment relative humidity.

[0068] The dehumidification operation mode or the humidification operation mode is determined by using the corrected current outdoor environment relative humidity. The dehumidification operation mode or the humidification operation mode can be accurately determined according to the absolute value of the difference between the current outdoor temperature and the preset outdoor humidity.

[0069] Optionally, correcting the current outdoor environment relative humidity according to the current power to obtain a corrected current outdoor environment relative humidity includes:

[0070] The current outdoor environment relative humidity is corrected according to the formula W=W1-β×(T1-T) / 100, where W is the corrected current outdoor environment relative humidity, W1 is the current outdoor environment relative humidity, T1 is the current outdoor temperature, T is the preset outdoor temperature, β is a coefficient related to the current power, and 0<β≤1.

[0071] For example, when T is 25°C, T1 is 35°C, and β=1, W=W1-β×(T1-T)%=W1-10 / 100=W1-10%.

[0072] By introducing T1 and T, the influence of temperature on relative humidity can be eliminated or reduced. By introducing β and 0<β≤1, the influence of the difference between T1 and T on relative humidity can be controlled to avoid the difference between T1 and T being too large, which makes the value of W unreasonable. Therefore, the dehumidification operation mode or humidification operation mode determined according to the corrected current outdoor environment relative humidity can be more accurate, and the humidification effect can be improved.

[0073] Alternatively, β is determined as follows:

[0074] If the current power is less than the first threshold, β=β1;

[0075] If the current power is greater than the second threshold, β=β2;

[0076] If the current power is greater than or equal to the first threshold and less than or equal to the second threshold, β=β3;

[0077] The first threshold is smaller than the second threshold, β1>β3>β2.

[0078] The larger the current power is, the larger the absolute value of the difference between the current outdoor temperature and the preset outdoor humidity is, and the larger the difference between T1 and T is. To avoid unreasonable W values, β should be smaller at this time.

[0079] Optionally, determining a dehumidification operation mode or a humidification operation mode according to the corrected current outdoor environment relative humidity includes:

[0080] When the air conditioner is running a dehumidification operation, if the corrected current outdoor environment relative humidity is greater than the first preset relative humidity, the internal circulation dehumidification is turned on; if the corrected current outdoor environment relative humidity is less than or equal to the first preset relative humidity, the external circulation dehumidification is turned on;

[0081] When the air conditioner is running a humidification operation, if the corrected current outdoor environment relative humidity is greater than the second preset relative humidity, the external circulation humidification is turned on; if the corrected current outdoor environment relative humidity is less than or equal to the second preset relative humidity, the internal circulation humidification is turned on.

[0082] In the case of dehumidification operation, when the corrected current outdoor environmental relative humidity is greater than the first preset humidity, it means that the corrected current outdoor environmental relative humidity is relatively large, 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 room to avoid increasing the indoor humidity; when the corrected current outdoor environmental relative humidity is less than or equal to the first preset humidity, it means that the corrected current outdoor environmental relative humidity is relatively small, 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 room.

[0083] In the case of humidification operation, when the corrected current outdoor environment relative humidity is greater than the second preset humidity, it means that the corrected current outdoor environment relative humidity is relatively large, 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 corrected current outdoor environment relative humidity is less than or equal to the second preset humidity, it means that the corrected current outdoor environment relative humidity is relatively small, 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.

[0084] Optionally, the control method further includes: determining a first preset power and a second preset power according to a target temperature of the air conditioner.

[0085] In a specific embodiment, in combination Figure 2 As shown, the control method includes:

[0086] Step S201, obtaining the current power of the compressor of the air conditioner.

[0087] Step S202: If the current power is greater than the first preset power, a dehumidification operation is performed.

[0088] Step S203, when the dehumidification operation is performed, the current outdoor environment relative humidity is obtained, and the current outdoor environment relative humidity is corrected according to the current power to obtain the corrected current outdoor environment relative humidity.

[0089] Step S204: the air conditioner determines a dehumidification operation mode according to the corrected current outdoor environment relative humidity. The dehumidification operation modes include internal circulation dehumidification and external circulation dehumidification.

[0090] Step S205, when the air conditioner is running a dehumidification operation, if the corrected current outdoor environment relative humidity is greater than the first preset relative humidity, the air conditioner starts the internal circulation dehumidification; if the corrected current outdoor environment relative humidity is less than or equal to the first preset relative humidity, the air conditioner starts the external circulation dehumidification.

[0091] Step S206: if the current power is less than the second preset power, the air conditioner performs a humidification operation; wherein the first preset power is greater than the second preset power.

[0092] Step S207, when the humidification operation is performed, the air conditioner obtains the current outdoor environment relative humidity, and the air conditioner corrects the current outdoor environment relative humidity according to the current power to obtain the corrected current outdoor environment relative humidity.

[0093] Step S208, the air conditioner determines a humidification operation mode according to the corrected current outdoor environment relative humidity, and the humidification operation modes include internal circulation humidification and external circulation humidification.

[0094] Step S209, when the air conditioner is running a humidification operation, if the corrected current outdoor environment relative humidity is greater than the second preset relative humidity, the air conditioner starts external circulation humidification; if the corrected current outdoor environment relative humidity is less than or equal to the second preset relative humidity, the air conditioner starts internal circulation humidification.

[0095] In a specific embodiment, the control method includes:

[0096] The cloud collects the compressor power parameter range W under indoor comfortable temperature and humidity, 1.2W is the first preset power, 0.8W is the second preset power, after the air conditioner runs for a preset time (for example, 30 minutes), the compressor power W1 (current power W1) in actual operation at a certain frequency, if W1>1.2W, turn on dehumidification, when the corrected current outdoor environment relative humidity>60%, turn on the internal circulation dehumidification, and enter the internal circulation dehumidification mode; when the corrected current outdoor environment relative humidity is ≤60%, turn on the external circulation dehumidification to avoid poor indoor dehumidification effect due to high outdoor environment humidity. W1<0.8W, turn on humidification; 1.2W≤W1≤0.8W, maintain the module status unchanged. The above re-judgment is performed every 1 hour.

[0097] Optionally, the control method further includes:

[0098] When the air conditioner is in a dehumidification operation, if the operating environment parameter of the air conditioner is greater than a first threshold, the speed of the dehumidification fan is increased; if the operating environment parameter of the air conditioner is less than the first threshold, the speed of the dehumidification fan is reduced; if the operating environment parameter is equal to the first threshold, the speed of the dehumidification fan remains unchanged; and / or

[0099] When the air conditioner is running in humidification operation, if the operating environment parameter of the air conditioner is greater than the first threshold, the speed of the dehumidifying fan is reduced; if the operating environment parameter of the air conditioner is less than the first threshold, the speed of the dehumidifying fan is increased; if the operating environment parameter is equal to the second threshold, the speed of the dehumidifying fan remains unchanged.

[0100] The operating environment parameters of the air conditioner can be the amount of condensed water in the indoor unit of the air conditioner or the wind resistance of the evaporator. In the case of dehumidification operation, the greater the amount of condensed water or the wind resistance of the evaporator, the greater the indoor humidity, the higher the speed of the hygroscopic fan increases, and 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; the smaller the amount of condensed water or the wind resistance of the evaporator, the smaller the indoor humidity, the speed of the hygroscopic fan decreases, and the hygroscopic fan can drive less 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 when flowing through the hygroscopic material and discharge it to the outdoors, thereby achieving precise dehumidification.

[0101] In the case of humidification operation, the smaller the amount of condensed water or the wind resistance of the evaporator, the lower the indoor humidity, the higher the speed of the hygroscopic fan, and 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 into the room, thereby achieving rapid humidification; the larger the amount of condensed water or the wind resistance of the evaporator, the greater the indoor humidity, the lower the speed of the hygroscopic fan, and the hygroscopic fan can drive less 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 when flowing through the hygroscopic material and discharge it into the room, thereby achieving precise humidification.

[0102] In a specific embodiment, under the condition of dehumidification operation: the condensation water level is obtained by the condensation water level sensor, the condensation water level corresponds to the condensation water amount, the preset water level is h, and the current condensation water amount h1 is obtained. If h1<0.85h, the speed of the dehumidification fan is reduced by 10%; if 0.85h≤h1≤1.15h, the speed of the dehumidification fan is kept unchanged; if 1.15h

[0103] In the case of humidification operation: if h1<0.85h, the speed of the dehumidification fan increases by 10%; 0.85h≤h1≤1.15h, the speed of the dehumidification fan remains unchanged; 1.15h
