[0003] During operation, the indoor unit of an air conditioner is affected by fluctuations in input voltage, causing the fan speed to fluctuate. When the motor speed abnormally increases due to input voltage fluctuations, the noise of the indoor unit will increase; when the motor speed abnormally decreases due to input voltage fluctuations, it will affect the cooling or heating effect of the air conditioner, thus affecting the user experience.

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0033] The operating principle of the air conditioner involved in the embodiments of this application is described in detail below:

[0034] like Figure 1As shown, the compressor compresses the refrigerant and delivers it through pipes to the condenser. The high-temperature, high-pressure gaseous refrigerant releases heat in the condenser, transforming into a medium-temperature, high-pressure liquid refrigerant. Then, the medium-temperature, high-pressure liquid refrigerant is depressurized through a capillary tube (throttling unit) to become a low-temperature, low-pressure liquid refrigerant. This low-temperature, low-pressure liquid refrigerant is then delivered to the evaporator, where it evaporates into a gas, absorbing a large amount of heat during the evaporation process. Finally, the low-temperature, low-pressure gaseous refrigerant in the evaporator is delivered to the compressor to participate in the next cycle. When the air conditioner is cooling, the outdoor unit's heat exchanger acts as the condenser, and the indoor unit's heat exchanger acts as the evaporator; conversely, when the air conditioner is heating, the outdoor unit's heat exchanger acts as the evaporator, and the indoor unit's heat exchanger acts as the condenser.

[0035] In daily household air conditioning use, unstable input voltage may occur, such as due to unstable mains voltage or when using solar or wind power. Unstable input voltage can cause unstable motor speed, leading to increased noise or poorer cooling / heating performance. As shown in Table 1 below, the relationship between motor voltage and speed is usually linear; that is, within a certain range, increasing the voltage will lead to an increase in speed. Motor speed can be controlled by changing the voltage. For example, when a higher motor speed is needed, the voltage can be increased to increase the speed; conversely, when a lower motor speed is needed, the voltage can be decreased to decrease the speed.

[0037] Table 1

[0038] The air conditioner control method for reducing the impact of voltage fluctuations provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0039] like Figure 2 As shown in the embodiment of this application, an air conditioner control method for reducing the impact of voltage fluctuations is provided. The method may include the following steps 201 and 202:

[0040] Step 201: During the operation of the air conditioner, obtain the voltage values ​​of the input voltage at different times to obtain voltage change information.

[0041] For example, during air conditioning operation, the air conditioner adjusts the indoor unit fan speed according to the user's set fan speed or the compressor's operating frequency. However, due to fluctuations in input voltage, the fan speed may differ from the set value. To determine whether the indoor unit fan speed exceeds the set value, it is necessary to sample the air conditioner's input voltage.

[0042] Specifically, step 201 above may include steps 201a1 and 201a2:

[0043] Step 201a1: Obtain the voltage value of the input voltage at each moment according to the preset sampling period.

[0044] Step 201a2: Generate the voltage change information based on the target voltage value of the input voltage obtained within a preset time period.

[0045] The target voltage value includes: the input voltage value obtained at the current moment, and the input voltage values ​​obtained at multiple moments prior to the current moment.

[0046] For example, by acquiring the input voltage values ​​at each time point according to a preset sampling period, the acquired input voltage values ​​at each time point can be calculated and statistically analyzed to obtain voltage change information.

[0047] Specifically, the voltage values ​​of the input voltage can be selected at various times within a period of time before the current time (i.e., the preset duration mentioned above) to generate voltage change information.

[0048] Step 202: Generate corresponding target parameters based on the voltage change information, and control the target motor based on the target parameters so that the speed of the target motor meets the expectation.

[0049] The target motor is the motor in the indoor unit of the air conditioner; the target parameters include at least one of the following: the rate of change of the input voltage, the root mean square error of the input voltage, and the difference between the input voltage and the preset voltage.

[0050] For example, based on the voltage change information mentioned above, the rate of change of the input voltage, the mean square error of the input voltage, and the difference between the input voltage and the preset voltage can be obtained. Based on one or more of the following, it can be determined whether the speed of the target motor needs to be adjusted, and the specific adjustment amount.

[0051] For example, the purpose of controlling the target motor based on the target parameters is to eliminate the influence of voltage fluctuations on the target motor speed, so that the target motor speed is consistent with or has a small error when the input voltage is normal.

[0052] It should be noted that, in the embodiments of this application, the target motor can be controlled based on one or more of the target parameters. The more parameters there are, the better the adjustment effect.

[0053] Optionally, in this embodiment of the application, the speed adjustment amount of the target motor can be determined by the following steps, and the speed of the target motor can be adjusted based on the speed adjustment amount.

[0054] Specifically, generating the corresponding target parameters based on the voltage change information in step 202 above may include at least one of the following steps: 202a1, 202a2, and 202a3:

[0055] Step 202a1: Calculate the rate of change of the input voltage at the current moment based on the voltage change information.

[0056] Step 202a2: Calculate the mean square error of the input voltage at the current moment based on the voltage change information.

[0057] Step 202a3: Calculate the difference between the current input voltage and the preset voltage based on the voltage change information.

[0058] It should be noted that the rate of change of the input voltage reflects how fast the input voltage changes. Adjusting the speed of the target motor based on the rate of change of the input voltage allows for advance adjustment of the speed, reducing the number of adjustments. The mean square error of the input voltage reflects the dispersion of the input voltage value at various times. Adjusting the speed of the target motor based on the mean square error of the input voltage can effectively avoid excessive adjustment, and to a certain extent, ensure the stability and consistency of the air conditioner's cooling and heating effects. The difference between the input voltage and the preset voltage reflects the difference between the current voltage and the standard voltage (e.g., 220V), and also indicates whether the voltage is increasing or decreasing. Based on this difference between the input voltage and the preset voltage, the direction of the target motor speed adjustment can be determined, i.e., whether to increase or decrease the speed.

[0059] Furthermore, after obtaining the target parameters, step 202 above may also include the following steps 202b1 and 202b2:

[0060] Step 202b1: Obtain the first weight corresponding to the rate of change of the input voltage in the target parameters, the second weight corresponding to the mean square error of the input voltage in the target parameters, and the third weight corresponding to the difference between the input voltage and the preset voltage in the target parameters.

[0061] Step 202b2: Based on the first weight, the second weight, the third weight, and the target parameter, calculate the motor speed adjustment value corresponding to the current moment.

[0062] For example, based on each of the target parameters mentioned above, the corresponding speed adjustment value can be calculated. Then, based on the weight of each parameter, the final speed adjustment value can be obtained.

[0063] Specifically, step 202b2 above may also include the following steps 202b21 ​​and 202b22:

[0064] Step 202b21: Determine a first adjustment value based on the rate of change of the input voltage in the target parameters; determine a second adjustment value based on the mean square error of the input voltage in the target parameters; and determine a third adjustment value based on the difference between the input voltage in the target parameters and the preset voltage.

[0065] Step 202b22: The motor speed adjustment value is obtained by weighting the first adjustment value and its corresponding first weight, the second adjustment value and its corresponding second weight, and the third adjustment value and its corresponding third weight.

[0066] The first adjustment value is positively correlated with the rate of change of the input voltage in the target parameter; the second adjustment value is positively correlated with the mean square error of the input voltage in the target parameter; and the third adjustment value is positively correlated with the difference between the input voltage in the target parameter and the preset voltage.

[0067] Understandably, the greater the rate of change of the input voltage, the greater the speed adjustment value of the target motor, meaning a larger adjustment value is needed to eliminate the impact of the excessively rapid rate of change of the input voltage on the normal operation of the air conditioner. The greater the mean square deviation of the input voltage, the greater the fluctuation range of the input voltage, and the greater the corresponding speed adjustment value of the target motor, so that the speed of the target motor is always kept within a small fluctuation range.

[0068] Specifically, after step 202b22 above, step 202 may further include the following steps 202c1 and 202c2:

[0069] Step 202c1: Determine the voltage adjustment value corresponding to the motor speed adjustment value based on the motor speed adjustment value and the set speed of the target motor.

[0070] Step 202c2: Incrementally adjust the input voltage of the target motor based on the voltage adjustment value.

[0071] The difference between the adjusted rotational speed of the target motor and its set rotational speed is less than a preset error value. The voltage adjustment value can be positive or negative.

[0072] Understandably, the fan motor in an indoor unit is typically an AC asynchronous motor, which is an electric drive device that converts electrical energy into mechanical energy. It mainly consists of a stator, a rotor, and the air gap between them. When AC current is applied to the stator windings, the stator generates a rotating magnetic field that cuts the rotor, thus generating torque. The higher the input voltage, the stronger the magnetic field, and the faster the rotor speed. Therefore, the speed of the target motor can be adjusted by changing the input voltage.

[0073] It should be noted that the adjustment of the target motor input voltage is performed incrementally according to the voltage adjustment value calculated in the above steps. That is, when adjusting the target motor input voltage, it is not necessary to consider the current input voltage of the target motor.

[0074] For example, such as Figure 3 The diagram shown is a flowchart illustrating an air conditioner control method for reducing the impact of voltage fluctuations provided in an embodiment of this application. Figure 3 As shown, during operation, the air conditioner samples its input voltage according to a preset sampling period. Then, it calculates the rate of change of the input voltage, the root mean square error of the input voltage, and the difference between the input voltage and 220V (the preset voltage mentioned above). Furthermore, it calculates the speed adjustment value P1 corresponding to the rate of change of the input voltage, the speed adjustment value P2 corresponding to the root mean square error of the input voltage, and the speed adjustment value P3 corresponding to the difference between the input voltage and 220V.

[0075] After obtaining the speed adjustment values ​​P1, P2, and P3, a weighted average can be calculated based on the speed adjustment value W1 corresponding to the rate of change of the input voltage, the speed adjustment value W2 corresponding to the mean square deviation of the input voltage, and the speed adjustment value W3 corresponding to the difference between the input voltage and 220V, to obtain the speed adjustment value P. Finally, the voltage adjustment value Q of the target motor is determined based on this speed adjustment value P, and the voltage of the indoor unit's motor is adjusted based on this voltage adjustment value Q.

[0076] The air conditioner control method for reducing the impact of voltage fluctuations provided in this application acquires the input voltage values ​​at different times during air conditioner operation to obtain voltage change information. Then, based on the voltage change information, corresponding target parameters are generated, and the target motor is controlled based on these target parameters to ensure that the target motor's speed meets expectations. The target motor is the motor in the indoor unit of the air conditioner. The target parameters include at least one of the following: the rate of change of the input voltage, the root mean square error of the input voltage, and the difference between the input voltage and a preset voltage. This allows the air conditioner to operate stably even when the input voltage fluctuates, greatly improving the user experience.

[0077] It should be noted that the air conditioner control method for reducing the impact of voltage fluctuations provided in this application embodiment can be executed by an air conditioner control device for reducing the impact of voltage fluctuations, or by a control module within that air conditioner control device for executing the air conditioner control method for reducing the impact of voltage fluctuations.
