Description

Technical Field

[0001] The present disclosure relates to the field of air conditioners, and in particular to an air conditioner, a control method for an air conditioner, a control device, and a storage medium. Background Art

[0002] With the continuous improvement of living standards, air conditioners have become one of the indispensable electrical appliances in production and life. When it is necessary to reduce the humidity of the environment, the air conditioner dehumidification operation is mainly to dehumidify through refrigeration. Therefore, during the dehumidification process, the indoor ambient temperature will be reduced simultaneously. If the room temperature drops too much, it will make the user feel colder. In some environments with strict requirements on temperature and humidity, if air conditioners are used for refrigeration and dehumidification, the temperature of the environment will be reduced, affecting the temperature of the current environment.

[0076] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0077] In this disclosure, unless otherwise stated, "inside" and "outside" refer to the inside and outside relative to the contour of the corresponding component itself. The terms "first" and "second" used in this disclosure are to distinguish one element from another element and have no order or importance.

[0078] During the dehumidification process of the air conditioner, in order to avoid the room temperature from dropping too much and affecting the user, there are three ways to achieve this: one way is to periodically start and stop the air conditioner. Another way is to control the air conditioner to shut down when the room temperature drops too much compared to the temperature when it is turned on. Another way is to add a throttle valve to the air conditioner indoor unit to adjust the cooling capacity and dehumidification capacity to avoid the room temperature from dropping too quickly. Among them, the first two methods prevent the room temperature from dropping too much by shutting down, but the ambient humidity cannot be adjusted during shutdown, and the humidity in the environment is prone to large fluctuations. The user experience is not stable enough, and it cannot be adapted to occasions that require constant humidity. The last method is relatively stable when controlling temperature and humidity, but the refrigeration system requires additional throttling elements, which increases the structural complexity and cost.

[0079] In order to solve the above problems, the present disclosure provides an air conditioner. Figure 1 A side cross-sectional view of an air conditioner provided by an exemplary embodiment of the present disclosure, Figure 2 The following is a schematic block diagram of the structure of an air conditioner provided by an exemplary embodiment of the present disclosure. Figure 1 and Figure 2 As shown, the air conditioner 100 includes: an indoor heat exchanger 101, a wind wheel device 102 and a wind wheel power supply circuit 103.

[0080] The air conditioner 100 provided in the embodiment of the present disclosure may be an indoor unit of an air conditioner, and may be used in a vertical, hanging or movable manner. The embodiment of the present disclosure does not limit the use form of the air conditioner 100.

[0081] The indoor heat exchanger 101 is used to condense the air flowing into the air conditioner 100 through the refrigerant in the dehumidification mode to dehumidify the air. It is understandable that the indoor heat exchanger 101 may include one or more groups of heat exchangers. The location of the indoor heat exchanger 101 in the air conditioner can be determined according to the specific form of the air conditioner, and the embodiment of the present disclosure does not limit the specific form of the indoor heat exchanger 101.

[0082] The wind wheel device 102 is arranged at the air outlet of the air conditioner 100, wherein the air dehumidified by the indoor heat exchanger 101 flows through the wind wheel device 102 and then flows out from the air outlet. The wind wheel device 102 in the embodiment of the present disclosure can form an airflow by rotating, and the air passing through the indoor heat exchanger 101 is formed into an airflow and blown out from the air outlet. It can be understood that the wind wheel device 102 can adopt a wind wheel form such as cross flow, centrifugal, mixed flow or axial flow, and the embodiment of the present disclosure does not limit the specific form of the wind wheel device 102.

[0083] In such Figure 1 In the example, the air conditioner adopts the form of a wall-mounted air conditioner, and the wind wheel device 102 adopts the form of a cross-flow, which does not represent a limitation of the specific form of the wind wheel device 102 in the embodiment of the present disclosure. When the wind wheel device 102 rotates, it generates an airflow flowing out to the air outlet, and the air outside the air conditioner 100 is sucked into the air conditioner 100 from the air inlet above the air conditioner. The air first flows through the indoor heat exchanger 101. When the indoor heat exchanger 101 is cooling, the air can exchange heat with the indoor heat exchanger 101, and the water vapor in the air can be condensed in the indoor heat exchanger 101, so as to remove part of the water vapor in the air. The air after the heat exchange with the indoor heat exchanger 101 continues to flow through the wind wheel device 102 and then flows out from the air outlet.

[0084] The wind wheel power supply circuit 103 is conductively connected to the wind wheel device 102, and is used to apply voltage to the wind wheel device 102 when the indoor heat exchanger 101 is in the dehumidification mode, so that the wind wheel device 102 generates heat, so that the difference between the temperature of the air flowing into the air conditioner 100 and the temperature of the air flowing out of the air outlet is less than or equal to a preset threshold.

[0085] The wind wheel power supply circuit 103 in the embodiment of the present disclosure can be set independently of other parts of the air conditioner 100, or can be connected to the power supply circuit of the air conditioner mainboard, or the power supply circuit of the air conditioner mainboard can be directly used as the wind wheel power supply circuit 103. The embodiment of the present disclosure does not limit the specific form of the power supply circuit. The heat generated by the wind wheel device 102 can be heat exchanged with the air flowing through, so that the temperature of the air with a lower temperature after passing through the indoor heat exchanger 101 is increased. By controlling the size of the heat generated by the wind wheel device 102, the difference between the temperature of the air flowing out of the air outlet and the temperature of the air flowing into the air conditioner can be made less than or equal to the preset threshold. The size of the preset threshold can be determined according to actual needs. For example, the preset threshold can be set to a value between 0-1. By setting the size of the preset threshold, the difference between the temperature of the air flowing out of the air outlet and the temperature of the air flowing into the air conditioner 100 is small, or the temperature of the air flowing out of the air outlet and the temperature of the air flowing into the air conditioner 100 can be equal, so that the air flowing out of the air outlet does not drastically affect the temperature of the air in the environment, and dehumidification is achieved without lowering the temperature of the environment.

[0086] Through the above technical solution, by setting the wind wheel device 102 to be heatable, during the cooling and dehumidification process, the wind wheel device 102 can generate heat under the voltage applied by the wind wheel power supply circuit 103, and can heat the air with a lower temperature passing through the indoor heat exchanger 101. The difference between the temperature of the air heated by the wind wheel device 102 and the temperature of the air flowing into the air conditioner 100 is less than or equal to the preset threshold, so that the temperature of the air blown out by the air conditioner 100 is equivalent to the temperature of the air entering the air conditioner 100, and the air flowing out of the air outlet does not drastically affect the temperature of the air in the environment. While the indoor temperature does not drop significantly, the air is dehumidified, achieving constant temperature dehumidification, improving user comfort, and ensuring the temperature requirements of the environment. In addition, there is no need to add additional throttling elements to the air conditioner, reducing system costs.

[0087] In addition, a heating device can be provided in the indoor heat exchanger 101 to heat the air cooled by the indoor heat exchanger 101. However, such a heating device is very close to the indoor heat exchanger 101 and has a small heating range. It can only heat a small part of the air flowing through the indoor heat exchanger 101, while the other part of the air flowing through the indoor heat exchanger 101 is not heated, so that the phenomenon of cold and hot air converging occurs, and the converging of cold and hot air easily forms condensed water. The wind wheel device 102 in the embodiment of the present disclosure is far away from the indoor heat exchanger 101, and the heating area of ​​the wind wheel device 102 is larger. It can heat most of the air flowing through the indoor heat exchanger 101, and the situation that most of the air is not heated will not occur. It is difficult for the phenomenon of cold and hot air converging to occur, and it is difficult to form condensed water, so that the air conditioner 100 will not blow water, thereby improving the user experience.

[0088] In an exemplary embodiment, Figure 1 As shown, the wind wheel device 102 may include a wind wheel body 121, a first conductive wheel 122 and a second conductive wheel 123. The first conductive wheel 122 is arranged at the first end of the wind wheel body 121, and the second conductive wheel 123 is arranged at the second end of the wind wheel body 121. The first conductive wheel 122 and the second conductive wheel 123 may be made of conductive materials. It should be noted again that Figure 1 and Figure 2 The wind wheel shown is a cross-flow type, which does not represent a limitation of the specific form of the wind wheel device 102 in the embodiment of the present disclosure.

[0089] The wind rotor device 102 can generate heat in two forms. In an exemplary embodiment, the wind rotor body 121 can be made of a conductive heating material. For example, the wind rotor body 121 can be made of a plastic part mixed with carbon fiber and injection molded. Under the action of electric current, the wind rotor body 121 can generate heat as a whole. The first conductive wheel 122 and the second conductive wheel 123 are arranged at both ends of the wind rotor body 121. The current can flow from one of the conductive wheels through the wind rotor body 121 and then flow through the other conductive wheel, so that the wind rotor body 121 can generate heat under the action of the electric current.

[0090] In another exemplary embodiment, the wind wheel device 102 may further include a conductive heating element disposed on the wind wheel body 121, and the conductive heating element is electrically connected to both the first conductive wheel 122 and the second conductive wheel 123. The conductive heating element may be a chip resistor or other forms of heating components, and the current may flow from one of the conductive wheels through the conductive heating element and then through the other conductive wheel. The conductive heating element generates heat under the action of the current.

[0091] In order to be electrically connected to the wind wheel device 102, Figure 2 As shown, the wind rotor power supply circuit 103 may include a first brush 131 and a second brush 132, the first brush 131 is electrically connected to the first conductive wheel 122, and the second brush 132 is electrically connected to the second conductive wheel 123. Since the wind rotor body 121 in the wind rotor device 102 needs to generate airflow by rotating during operation, the wind rotor power supply circuit 103 can supply power to the wind rotor body 121 or a conductive heating element disposed on the wind rotor body 121 through a brush connection during the rotation of the wind rotor body 121.

[0092] In an exemplary embodiment, Figure 2 As shown, the wind wheel device 102 may further include a driving motor 105, a rotating shaft 151 of the driving motor 105 being insulated and connected to the first end of the wind wheel body 121, and the first conductive wheel 122 having an opening, the rotating shaft 151 passing through the opening and connected to the wind wheel body 121, and a gap being provided between the opening of the first conductive wheel 122 and the rotating shaft 151.

[0093] The driving motor 105 can drive the wind rotor body 121 to rotate. Since there is current inside the wind rotor body 121 during operation, or there is current in the conductive heating element provided on the wind rotor body 121, the part where the rotating shaft 151 of the driving motor 105 is connected to the wind rotor body 121 can be provided with insulating material or connected through an insulating bearing. The embodiment of the present disclosure does not limit the insulating connection form between the rotating shaft and the wind rotor body 121. In addition, insulating material or insulating bearings can be provided in the gap between the first conductive wheel 122 and the rotating shaft 151, so that the first conductive wheel 122 is insulated from the rotating shaft 151, so that the current flowing through the first conductive wheel 122, the wind rotor body 121 or the conductive heating element will not flow to the driving motor 105 through the rotating shaft 151, and affect the driving motor 105. It can be understood that the wind rotor power supply circuit 103 in the embodiment of the present disclosure is used to supply electric energy for the heating of the wind rotor device 102. The electric energy required for the rotation of the driving motor 105 can be provided by other circuits.

[0094] It is understandable that, in order to improve the rotation stability of the wind rotor body 121, an opening may also be provided on the second conductive wheel 123, and the wind rotor body 121 may be connected to other components of the air conditioner through another rotating shaft passing through the opening on the second conductive wheel 123. Similarly, the other rotating shaft passing through the opening on the second conductive wheel 123 is also insulated from the wind rotor body 121. A gap, insulating material or insulating bearing may also be provided between the second conductive wheel 123 and the other rotating shaft to achieve insulation between the second conductive wheel 123 and the other rotating shaft, so as to prevent the current flowing through the second conductive wheel 123 and the wind rotor body 121 from flowing to other components through the other rotating shaft.

[0095] For example Figure 2 As shown, the air conditioner 100 may further include a controller 104 , which is connected to the wind wheel power supply circuit 103 , and is used to adjust the voltage applied by the wind wheel power supply circuit 103 to the wind wheel device 102 .

[0096] Figure 3 The flowchart of the method provided by the controller 104 for adjusting the voltage applied to the wind wheel device 102 by the wind wheel power supply circuit 103 is provided as an exemplary embodiment of the present disclosure. Figure 3 As shown, in detail, the controller 104 adjusts the voltage applied to the wind wheel device 102 by the wind wheel power supply circuit 103 through the following steps S11 to S15.

[0097] In step S11, the current ambient temperature and the target temperature are obtained.

[0098] The current ambient temperature can be detected by a temperature sensor provided on the air conditioner 100, or can be detected by a temperature sensor provided in the environment through communication connection with the controller 104. The target temperature is set in a control instruction sent by a user to the air conditioner 100 through a remote controller, a mobile terminal or other device, or the target temperature is a pre-set temperature adapted to the environment. The embodiments of the present disclosure do not limit the manner in which the current ambient temperature and the target temperature are obtained.

[0099] In step S12, it is determined whether the heating condition is satisfied according to the current ambient temperature and the target temperature.

[0100] The controller 104 can control the voltage applied by the wind wheel power supply circuit 103 to the wind wheel device 102. The controller 104 needs to determine whether the wind wheel power supply circuit 103 supplies power to the wind wheel device 102, and determine the voltage at which the wind wheel power supply circuit 103 supplies power to the wind wheel device 102 based on the relationship between the current ambient temperature and the target temperature.

[0101] The controller 104 may determine that the heating condition is satisfied when the difference between the current ambient temperature and the target temperature is less than a preset difference. The size of the preset difference may be determined according to actual needs, for example, the preset difference may be set to a value between 0 and 1. When the difference between the current ambient temperature and the target temperature is less than the value, it indicates that the current ambient temperature is close to the target temperature. At this time, there is no need to further reduce the ambient temperature, that is, it is determined that the heating condition is satisfied.

[0102] In step S13, the temperature of the indoor heat exchanger 101, the operating gear of the wind wheel device 102, and the resistance of the heating part of the wind wheel device 102 are obtained.

[0103] The temperature of the indoor heat exchanger 101 can be detected by a temperature sensor disposed inside or near the indoor heat exchanger 101. The wind wheel device 102 can be pre-set with multiple operating gears. Under different operating gears, the rotation speed of the wind wheel body 121 in the wind wheel device 102 is different. The current gear of the wind wheel device 102 can be determined according to the current operating state of the fan. The resistance of the heating part in the wind wheel device 102 can also be pre-configured in the controller 104.

[0104] In step S14 , the target voltage is determined according to the current ambient temperature, the temperature of the indoor heat exchanger 101 , the operating gear of the wind wheel device 102 , and the resistance of the heating part of the wind wheel device 102 .

[0105] When the heating conditions are met, the wind wheel device 102 can be controlled to generate heat. In the embodiment of the present disclosure, the amount of heat generated by the wind wheel device 102 is related to the cooling capacity of the indoor heat exchanger 101. The stronger the cooling capacity of the indoor heat exchanger 101, the greater the amount of heat that the wind wheel device 102 needs to generate. At the same time, the faster the wind wheel body 121 in the wind wheel device 102 rotates, the more heat needs to be generated, because the faster the air flow rate, the shorter the time for heat exchange between the air and the wind wheel device 102, and the wind wheel device 102 needs to generate more heat to heat the faster air. In addition, the resistance of the heat generating part of the wind wheel device 102 will also affect the heat generated by the wind wheel device 102. The controller 104 can obtain relevant parameters that affect the amount of heat generated by the wind wheel device 102 to determine the working voltage of the wind wheel device 102, thereby controlling the amount of heat generated by the wind wheel device 102 by determining the size of the target voltage.

[0106] In step S15, the voltage applied to the wind wheel device 102 by the wind wheel power supply circuit 103 is controlled to be the target voltage, so that the difference between the temperature of the air flowing into the air conditioner 100 and the temperature of the air flowing out of the air outlet is less than or equal to a preset threshold.

[0107] After the controller 104 determines the target voltage, it can control the wind wheel power supply circuit 103 to supply power to the wind wheel device 102 at the target voltage. Figure 2 In the wind wheel device 102 shown, the wind wheel power supply circuit 103 can supply power to the wind wheel body 121 or the conductive heating element through a brush. The wind wheel device 102 generates heat under the action of the current and exchanges heat with the air flowing through it, thereby heating the air after passing through the indoor heat exchanger 101, increasing the temperature of the air flowing out of the air conditioner 100, and making the difference between the temperature of the air flowing into the air conditioner 100 and the temperature of the air flowing out of the air outlet less than or equal to a preset threshold.

[0108] In this way, by setting the controller 104 in the air conditioner 100, when it is determined that the relationship between the current ambient temperature and the target temperature meets the heating condition, the target voltage of the wind wheel device 102 can be determined by the temperature of the indoor heat exchanger 101, the operating gear of the wind wheel device 102, and the resistance of the heating part of the wind wheel device 102. The heat generation of the wind wheel device 102 is controlled so that the difference between the temperature of the air flowing into the air conditioner 100 and the temperature of the air flowing out of the air outlet is less than or equal to the preset threshold. When the indoor heat exchanger 101 is dehumidifying, when the difference between the temperature of the air flowing into the air conditioner 100 and the temperature of the air flowing out of the air outlet is less than or equal to the preset threshold, the air is dehumidified without lowering the ambient temperature, and constant temperature dehumidification is achieved.

[0109] In an exemplary embodiment, the controller 104 is specifically configured to: determine that the first heating condition is satisfied when the current ambient temperature is less than the sum of the target temperature and a first constant, wherein the first constant is a positive number.

[0110] The first constant can be determined according to actual needs. For example, the first constant can be a value between 0 and 1. When the current ambient temperature is less than the sum of the target temperature and the first constant, it indicates that the current ambient temperature is close to the target temperature. At this time, the ambient temperature does not need to fluctuate violently. At this time, the heat emitted by the wind wheel device 102 can be controlled to be equivalent to the cooling capacity of the indoor heat exchanger 101, so that the difference between the temperature of the air flowing out of the air outlet and the temperature of the air flowing into the air conditioner 100 is less than or equal to the preset threshold, so as to achieve constant temperature dehumidification while the ambient temperature does not continue to decrease during cooling and dehumidification.

[0111] When the current ambient temperature is greater than the sum of the target temperature and the first constant, it indicates that the current ambient temperature is higher than the target temperature. The wind wheel device 102 does not need to heat the air flowing through it, and the indoor heat exchanger 101 can continue to operate in the cooling and dehumidification mode to cool the ambient air so that the temperature of the ambient air reaches the target temperature.

[0112] Specifically, when the first heating condition is met, the target voltage can be calculated by the following formula:

[0113]

[0114] Wherein, U is the target voltage, N is the operating gear of the wind rotor device 102, R is the resistance of the heating part of the wind rotor device 102, T 内环 is the current ambient temperature, T 内管 is the temperature of the indoor heat exchanger 101, k and c are preset positive constants.

[0115] In the embodiment of the present disclosure, the heating power P1 of the wind wheel device 102 can be calculated by P1=U 2 / R. The cooling power P2 of the indoor heat exchanger 101 can be expressed by P2 = k × N × R × (T_ 内环 -T_ 内管 ). When the heat generated by the wind wheel device 102 is equivalent to the cooling capacity of the indoor heat exchanger 101, the target voltage U of the wind wheel device 102 can be calculated. In addition, since part of the heat generation power of the wind wheel device 102 is used to increase its own temperature, the voltage constant c is compensated when calculating the target voltage. For example, c can take a value between 10-25. k can take a value between 20-40.

[0116] In this way, the controller 104 calculates the target voltage of the wind wheel device 102 based on the current ambient temperature, the temperature of the indoor heat exchanger 101, the operating gear of the wind wheel device 102, and the resistance of the heating part of the wind wheel device 102 when determining that the current ambient temperature is less than the sum of the target temperature and the first constant, so that the wind wheel power supply circuit 103 applies voltage to the wind wheel device 102 at the target voltage. The heat emitted by the wind wheel device 102 heats the air cooled by the indoor heat exchanger 101 again, so that the ambient temperature will not be reduced while cooling and dehumidifying, and the purpose of constant temperature dehumidification is achieved.

[0117] In another exemplary embodiment, the controller 104 is specifically configured to: determine that the second heating condition is satisfied when the current ambient temperature is less than the difference between the target temperature and the second constant. The second constant is a positive number less than the target temperature. For example, the second constant can take a value between 1 and 2.

[0118] When the current ambient temperature is less than the difference between the target temperature and the second constant, it indicates that the ambient temperature is significantly lower than the target temperature. In order to raise the ambient temperature to the target temperature, the heat generation of the wind wheel device 102 can be increased so that the temperature of the air flowing out of the outlet is greater than the temperature of the air flowing into the air conditioner 100.

[0119] Specifically, when the second heating condition is met, the target voltage can be calculated by the following formula:

[0120]

[0121] Wherein, d is a preset positive constant, for example, d can be a value between 25 and 50.

[0122] In this way, the heating power of the wind wheel device 102 is greater than the cooling power of the indoor heat exchanger 101. The air cooled and dehumidified by the indoor heat exchanger 101 can be heated to a higher temperature by the wind wheel device 102. The temperature of the air flowing out of the air outlet is greater than the temperature of the air flowing into the air conditioner 100, and the air in the environment will be heated up. When the ambient temperature continues to rise, when the current ambient temperature is less than the sum of the target temperature and the first constant, the wind wheel device 102 switches to the working state under the first heating condition and continues to perform constant temperature dehumidification.

[0123] Based on the same inventive concept, the embodiment of the present disclosure further provides a method for controlling an air conditioner, which is used to control the above-mentioned air conditioner 100 . The method for controlling an air conditioner includes the following steps S21 to 25 .

[0124] In step S21, when the air conditioner 100 is in the dehumidification mode, the current ambient temperature and the target temperature are obtained.

[0125] The air conditioner 100 can enter the dehumidification mode after receiving the user's dehumidification instruction or the pre-set dehumidification instruction takes effect, and condenses the water vapor in the air passing through by controlling the internal heat exchanger 102 to reduce the water vapor content in the air. In the dehumidification mode, as mentioned above, the current ambient temperature can be detected by a temperature sensor set on the air conditioner 100, or the current ambient temperature can be detected by a temperature sensor set in the environment. The target temperature can be the temperature that the user hopes the environment to reach set in the control instruction sent to the air conditioner 100 by a remote control, a mobile terminal or other device, or the target temperature can be a pre-set temperature adapted to the environment.

[0126] In step S22, it is determined whether the heating condition is satisfied according to the current ambient temperature and the target temperature.

[0127] In step S23 , the temperature of the indoor heat exchanger 101 of the air conditioner 100 , the operating gear of the wind wheel device 102 of the air conditioner 100 , and the resistance of the heating part of the wind wheel device 102 are obtained.

[0128] In step S24 , the target voltage is determined according to the current ambient temperature, the temperature of the indoor heat exchanger 101 , the operating gear of the wind wheel device 102 , and the resistance of the heating part of the wind wheel device 102 .

[0129] In step S25, the voltage applied to the wind wheel device 102 by the wind wheel power supply circuit 103 of the air conditioner 100 is controlled to be the target voltage, so that the difference between the temperature of the air flowing into the air conditioner 100 and the temperature of the air flowing out of the air outlet of the air conditioner 100 is less than or equal to a preset threshold.

[0130] Steps S22 to S25 are similar to the above-mentioned steps S12 to S15 and will not be described in detail here.

[0131] According to the control method of the air conditioner provided by the embodiment of the present disclosure, when it is determined that the relationship between the current ambient temperature and the target temperature meets the heating condition, the target voltage of the wind wheel device 102 can be determined by the temperature of the indoor heat exchanger 101, the operating gear of the wind wheel device 102, and the resistance of the heating part of the wind wheel device 102. The heat generation of the wind wheel device 102 is controlled so that the difference between the temperature of the air flowing into the air conditioner 100 and the temperature of the air flowing out of the air outlet is less than or equal to the preset threshold. When the indoor heat exchanger 101 is dehumidifying, when the difference between the temperature of the air flowing into the air conditioner 100 and the temperature of the air flowing out of the air outlet is less than or equal to the preset threshold, the air is dehumidified without lowering the ambient temperature, and constant temperature dehumidification is achieved. When the temperature of the air flowing out of the air outlet is greater than the temperature of the air flowing into the air conditioner 100, the ambient temperature is increased, and the ambient temperature can finally reach the target temperature, so that the air is dehumidified without continuously lowering the ambient temperature.

[0132] In an exemplary embodiment, step S22 of determining whether the heating condition is satisfied according to the current ambient temperature and the target temperature includes step S221 .

[0133] In step S221 , when the current ambient temperature is less than the sum of the target temperature and a first constant, it is determined that the first heating condition is satisfied, wherein the first constant is a positive number.

[0134] The step S24 of determining the target voltage according to the current ambient temperature, the temperature of the indoor heat exchanger 101 , the operating gear of the wind wheel device 102 and the resistance of the heating part in the wind wheel device 102 includes a step S241 .

[0135] In step S241, when the first heating condition is met, the target voltage is calculated by the following formula:

[0136]

[0137] Wherein, U is the target voltage, N is the operating gear of the wind rotor device 102, R is the resistance of the heating part of the wind rotor device 102, T 内环 is the current ambient temperature, T 内管 is the temperature of the indoor heat exchanger 101, k and c are preset positive constants.

[0138] The methods of step S221 and step S241 are similar to the method in which the controller 104 determines the first heating condition and the target voltage, and are not described in detail here.

[0139] In an exemplary embodiment, step S22 of determining whether the heating condition is satisfied according to the current ambient temperature and the target temperature may further include step S222.

[0140] In step S222, when the current ambient temperature is less than the difference between the target temperature and the second constant, it is determined that the second heating condition is satisfied, wherein the second constant is a positive number less than the target temperature;

[0141] According to the current ambient temperature, the temperature of the indoor heat exchanger 101 , the operating gear of the wind wheel device 102 , and the resistance of the heating part of the wind wheel device 102 , the step S24 of determining the target voltage may further include a step S242 .

[0142] In step S242, when the second heating condition is met, the target voltage is calculated by the following formula:

[0143]

[0144] d is a preset positive constant.

[0145] The methods of step S222 and step S242 are similar to the method in which the controller 104 determines the second heating condition and the target voltage, and are not described in detail here.

[0146] In another exemplary embodiment, Figure 4 The following is a flow chart of a method for controlling an air conditioner provided in an embodiment of the present disclosure. Figure 4 As shown, the air conditioner control method further includes the following steps S31 to S34.

[0147] In step S31, the current relative humidity and the target relative humidity are obtained.

[0148] The current relative humidity can be detected by a humidity sensor provided on the air conditioner 100, or can be obtained by other humidity sensors provided in the environment, or can be obtained from other terminals connected by communication. The target relative humidity can be the relative humidity that the user wants the environment to reach, or can be the relative humidity that the current environment needs to reach that is preset. The embodiments of the present disclosure do not limit the method for obtaining the current relative humidity and the target relative humidity.

[0149] In step S32, a target moisture content is calculated according to the target temperature and the target relative humidity.

[0150] The target temperature and target relative humidity can be used to calculate the corresponding moisture content under the relative humidity conditions that the environment needs to achieve. Moisture content refers to the mass of water vapor mixed in every kilogram of dry air.

[0151] In step S33, the current moisture content is calculated according to the current ambient temperature and the current relative humidity.

[0152] According to the current ambient temperature and the current relative humidity, the corresponding moisture content in the current environment can be calculated.

[0153] In step S34, when the current humidity is greater than the target humidity, the indoor heat exchanger is controlled to perform cooling and dehumidification.

[0154] By comparing the current humidity content with the target humidity content, when the current humidity content is greater than the target humidity content, it indicates that there is more water vapor in the current air. At this time, the indoor heat exchanger 101 can be controlled to dehumidify. The indoor heat exchanger 101 enters the dehumidification mode and can be controlled to heat the wind wheel device 102 when it is needed to heat up according to the above control method to achieve constant temperature dehumidification.

[0155] If it is determined that the current humidity content is less than the target humidity content, it indicates that there is less water vapor in the current ambient air and dehumidification is not required. At this time, the indoor heat exchanger 101 does not need to cool, and the wind wheel device 102 does not need to heat. The air conditioner 100 can enter the air supply mode without cooling and dehumidifying the ambient air.

[0156] In addition, when the air conditioner 100 in the embodiment of the present disclosure is not cooling, it is also possible to only put the wind wheel device 102 in a heating state to blow high-temperature air into the environment to heat the air in the environment. The wind wheel device 102 has a larger surface area, a higher heating efficiency, and a more uniform heat exchange.

[0157] In this way, by comparing the current humidity content with the target humidity content, the indoor heat exchanger 101 is controlled to enter the cooling and dehumidification mode. Since the humidity content directly reflects the current water vapor content in the air, the control of when the air conditioner 100 needs to be dehumidified is more precise, and the control of the ambient humidity is also more accurate, so that the air humidity in the environment can be maintained in a more comfortable state, thereby improving the user's comfort.

[0158] Based on the same inventive concept, Figure 5 As shown, the embodiment of the present disclosure also provides an air conditioner control device 500, which is applied to the air conditioner 100 in the above embodiment. The air conditioner control device 500 includes: a temperature acquisition module 501, a condition determination module 502, an acquisition module 503, a voltage determination module 504 and a control module 505.

[0159] The temperature acquisition module 501 is configured to obtain the current ambient temperature and the target temperature when the air conditioner 100 is in the dehumidification mode.

[0160] The condition determination module 502 is configured to determine whether the heating condition is satisfied according to the current ambient temperature and the target temperature.

[0161] The acquisition module 503 is configured to obtain the temperature of the indoor heat exchanger 101 of the air conditioner 100, the operating gear of the wind wheel device 102 of the air conditioner 100, and the resistance of the heating part of the wind wheel device.

[0162] The voltage determination module 504 is configured to determine the target voltage according to the current ambient temperature, the temperature of the internal heat exchanger, the operating gear of the wind wheel device and the resistance of the heating part of the wind wheel device.

[0163] The control module 505 is configured to control the voltage applied to the wind wheel device 102 by the wind wheel power supply circuit 103 of the air conditioner 100 to be a target voltage, so that the difference between the temperature of the air flowing into the air conditioner 100 and the temperature of the air flowing out from the air outlet of the air conditioner 100 is less than or equal to a preset threshold.

[0164] Regarding the device in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiment of the method, and will not be elaborated here.

[0165] Based on the same inventive concept, Figure 6 As shown, the embodiment of the present disclosure further provides an air conditioner control device 600 , which is applied to the above-mentioned air conditioner 100 and includes a memory 601 and a processor 602 .
