Description

Technical Field

[0001] The present application relates to the technical field of air conditioning equipment control, and particularly relates to an air conditioning equipment, a control method thereof, and a computer storage medium. Background Art

[0002] Air conditioning equipment usually has an unavailable resonance frequency range, that is, the air conditioning equipment will not operate at any frequency within this resonance frequency range except the maximum frequency and the minimum frequency. And if the frequency that the air conditioning equipment needs to use at this time (i.e., the control frequency) is within the resonance frequency range, at this time, usually the maximum frequency or the minimum frequency of this resonance frequency range is selected to control the operation of the air conditioning equipment, or the maximum frequency and the minimum frequency are alternately used to control the operation of the air conditioning equipment.

[0003] However, if the maximum frequency is selected to control the operation of the air conditioning equipment, it will not only increase the power consumption of the air conditioning equipment, but also cause the indoor environmental temperature to be relatively lower than the target temperature; if the minimum frequency is selected to control the operation of the air conditioning equipment, it will cause the indoor environmental temperature to be relatively higher than the target temperature; if the maximum frequency and the minimum frequency are alternately used to control the operation of the air conditioning equipment, the service life of the compressor of the air conditioning equipment will be affected due to the too frequent switching of the control frequency. In summary, at present, when the control frequency of the air conditioning equipment is within the resonance frequency range, the control effect on the air conditioning equipment is poor.

[0018] When the difference between the control frequency and the maximum frequency is small, use the maximum frequency as the target control frequency;

[0019] When the difference between the control frequency and the minimum frequency is small, use the minimum frequency as the target control frequency.

[0020] Optionally, the control method of the air conditioning device further includes:

[0027] Optionally, the obtaining of the control frequency and the fan speed of the air conditioning device includes:

[0028] Obtain at least two of the current ambient parameters, operating parameters, and set parameters;

[0029] Based on a preset control parameter model, use the obtained parameters as inputs and calculate the control frequency and the fan speed of the air conditioning device.

[0038] The present application provides a control method for an air conditioning device. First, the control frequency and the fan speed of the air conditioning device are obtained; when the control frequency of the air conditioning device is within a preset resonance frequency range, the maximum frequency or the minimum frequency of the preset resonance frequency range is determined as the target control frequency; then, according to the control frequency and the fan speed, the target fan speed corresponding to the target control frequency is determined; and then the air conditioning device is controlled to operate at the target control frequency and the target fan speed.

[0039] Therefore, when the control frequency of the air conditioning device is within the preset resonance frequency range, the control method adopted in the present application is not simply to control the operation of the air conditioning device at the maximum frequency or the minimum frequency, but during the process of the air conditioning device operating at the maximum frequency or the minimum frequency, by combining the adjustment of the fan speed required for the operation of the air conditioning device, the control of the air volume output by the air conditioning device is realized, so that the air conditioning device can obtain the same control effect as the control frequency operating within the resonance frequency range. Specifically, it can be manifested as follows: if the air conditioning device selects to operate at the maximum frequency of the preset resonance frequency range, the air volume output by the air conditioning device will be reduced by reducing the fan speed required for the operation of the air conditioning device, and the reduction of the air volume can avoid the problem that the air conditioning device outputs too much cooling capacity when operating at the maximum frequency, so that the indoor environmental temperature can just reach the target temperature; if the air conditioning device selects to operate at the minimum frequency of the preset resonance frequency range, the air volume output by the air conditioning device will be increased by increasing the fan speed required for the operation of the air conditioning device, and the increase of the air volume can avoid the problem that the air conditioning device outputs too little cooling capacity when operating at the minimum frequency, so that the indoor environmental temperature can reach the target temperature. In addition, during the process of controlling the operation of the air conditioning device, the present application does not involve the switching between the maximum frequency and the minimum frequency, so it can also avoid the influence on the service life of the compressor of the air conditioning device caused by frequent switching of the control frequency. It can be seen that the present application solves the technical problem of poor control effect on the air conditioning device when the control frequency of the air conditioning device is within the resonance frequency range, and improves the control effect on the air conditioning device by combining the adjustment of the fan speed.

[0048] To make the above objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0049] An air conditioning device usually has an unavailable resonance frequency range, that is, the air conditioning device will not operate at any frequency within this resonance frequency range except the maximum frequency and the minimum frequency. And if the frequency that the air conditioning device needs to use at this time (i.e., the control frequency) is within the resonance frequency range, at this time, usually the maximum frequency or the minimum frequency within this resonance frequency range is selected to control the operation of the air conditioning device, or the maximum frequency and the minimum frequency are alternately used to control the operation of the air conditioning device.

[0050] However, if the maximum frequency is selected to control the operation of the air conditioning device, it will not only increase the power consumption of the air conditioning device, but also cause the indoor environmental temperature to be relatively lower than the target temperature; if the minimum frequency is selected to control the operation of the air conditioning device, it will cause the indoor environmental temperature to be relatively higher than the target temperature; if the maximum frequency and the minimum frequency are alternately used to control the operation of the air conditioning device, it will affect the service life of the compressor of the air conditioning device due to the too frequent switching of the control frequency. In summary, currently, when the control frequency of the air conditioning device is within the resonance frequency range, the control effect on the air conditioning device is poor.

[0051] Based on this, the present application proposes a control method for an air conditioning device according to the first embodiment. Please refer to Figure 1 , the control method of the air conditioning device includes:

[0052] Step S10, obtain the control frequency and the fan speed of the air conditioning device;

[0053] In this embodiment, the air conditioning device can be the execution subject of the control method of the air conditioning device. The air conditioning device refers to a device that processes the air in the working space to keep the set temperature, humidity, and control the dust and harmful gas content in the working space. The air conditioning device can be an air conditioner, an air dehumidifier, an air humidifier, etc. This embodiment does not make specific limitations on this.

[0054] It should be noted that the control frequency refers to the frequency that the air conditioning device needs to use at the current moment, that is, the frequency that the compressor of the air conditioning device needs to reach at the current moment. The fan speed is the speed that the internal fan of the air conditioning device needs to reach at the current moment. When obtaining the control frequency and the fan speed of the air conditioning device, from the perspective of obtaining the frequency, it can be obtained in real time or periodically; from the perspective of the obtaining path, it can be obtained from the air conditioning device or from an external device connected to the air conditioning device. This embodiment does not make specific limitations on the obtaining methods of the control frequency and the fan speed of the air conditioning device.

[0055] Step S20, when the control frequency of the air conditioning device is within the preset resonance frequency range, determine the maximum frequency or the minimum frequency of the preset resonance frequency range as the target control frequency;

[0056] It should be noted that the preset resonance frequency range is used to characterize the frequency range in which the air conditioning equipment cannot operate. The number of preset resonance frequency ranges can be one or multiple, and this embodiment does not make specific limitations in this regard. It can be understood that, generally, there is at least one resonance frequency range in the air conditioning equipment, especially in the low-frequency band. When the air conditioning equipment operates at a frequency within the resonance frequency range, obvious jitter and noise will occur in the compressor of the air conditioning equipment, which will affect the service life of the compressor. Therefore, generally, the air conditioning equipment will not work at any frequency within this resonance frequency range. For example, reference can be made to Figure 2 , it can be assumed that the preset resonance frequency range of the air conditioning equipment is (9Hz, 11Hz), then the air conditioning equipment will not be able to operate at frequencies between 9Hz and 11Hz.

[0057] In addition, it should be noted that the target control frequency refers to the frequency that the air conditioning equipment actually uses at the current moment. It can be understood that if the preset resonance frequency range includes the upper boundary frequency, the maximum frequency of the preset resonance frequency range is the upper boundary frequency; if the preset resonance frequency range does not include the upper boundary frequency, the maximum frequency of the preset resonance frequency range is the frequency that is only lower than the upper boundary frequency in the preset resonance frequency range; if the preset resonance frequency range includes the lower boundary frequency, the minimum frequency of the preset resonance frequency range is the lower boundary frequency; if the preset resonance frequency range does not include the lower boundary frequency, the minimum frequency of the preset resonance frequency range is the frequency that is only higher than the lower boundary frequency in the preset resonance frequency range.

[0058] When determining the maximum or minimum frequency of the preset resonance frequency range as the target control frequency, it can be set to default to select a certain frequency as the target control frequency, that is, default to select the maximum frequency of the preset resonance frequency range as the target control frequency, or default to select the minimum frequency of the preset resonance frequency range as the target control frequency; in other embodiments, it can also be flexibly determined according to the actual situation whether to select the maximum frequency or the minimum frequency as the target control frequency, and this embodiment does not make specific limitations in this regard.

[0059] It can be understood that when the control frequency of the air conditioning device is within the preset resonance frequency range, it means that the air conditioning device will not operate at the required frequency at this time. Therefore, certain strategies need to be adopted to enable the indoor environmental temperature to reach the target temperature. At this time, if the control frequency changes suddenly, it will affect the service life of the compressor of the air conditioning device. Therefore, it is necessary to give priority to using a control frequency with a small change range and available for the operation of the air conditioning device to control the air conditioning device. For the situation where the control frequency is within the preset resonance frequency range, the frequencies that meet the conditions of a small change range and available for the operation of the air conditioning device at this time are the maximum frequency and the minimum frequency of the preset resonance frequency range. Therefore, the maximum frequency and the minimum frequency of the preset resonance frequency range need to be used to control the air conditioning device.

[0060] Step S30: Determine the target fan speed corresponding to the target control frequency according to the control frequency and the fan speed.

[0061] It should be noted that the target fan speed is the actual speed that the internal fan of the air conditioning device should reach at the current moment.

[0062] As an example, the historical control frequency, historical fan speed, and historical target fan speed of the air conditioning device can be used in advance as training samples to construct a fan speed model. Thus, when determining the target fan speed corresponding to the target control frequency according to the control frequency and the fan speed, the control frequency and the fan speed can be used as the input of the fan speed model to calculate the target fan speed corresponding to the target control frequency through the fan speed model. As another example, a fan speed configuration table for recording the target fan speeds corresponding to different control frequencies and fan speeds can be configured in advance. Thus, when determining the target fan speed corresponding to the target control frequency according to the control frequency and the fan speed, the control frequency and the fan speed can be used as index conditions to search for the target fan speed in the preset fan speed configuration table. It can be understood that the method of determining the target fan speed through the fan speed model has higher accuracy in determining the target fan speed because it can adapt to the actual situation of the air conditioning device in real time. And the method of determining the target fan speed through the fan speed configuration table has higher efficiency in determining the target fan speed because it can quickly find the corresponding target fan speed. The specific determination method of the target fan speed in this example is not specifically limited.

[0063] Step S40: Control the air conditioning device to operate according to the target control frequency and the target fan speed.

[0064] The embodiment of the present application provides a control method for an air conditioning device. First, the control frequency and the fan speed of the air conditioning device are obtained. When the control frequency of the air conditioning device is within the preset resonance frequency range, the maximum frequency or the minimum frequency of the preset resonance frequency range is determined as the target control frequency. Then, according to the control frequency and the fan speed, the target fan speed corresponding to the target control frequency is determined. Next, the air conditioning device is controlled to operate at the target control frequency and the target fan speed. Therefore, when the control frequency of the air conditioning device is within the preset resonance frequency range, the control method adopted is not simply to control the operation of the air conditioning device at the maximum frequency or the minimum frequency, but during the process of the air conditioning device operating at the maximum frequency or the minimum frequency, by combining the adjustment of the fan speed required for the operation of the air conditioning device, the control of the air volume output by the air conditioning device is realized, so that the air conditioning device can obtain the same control effect as the control frequency operating within the resonance frequency range.

[0065] Specifically, if the air conditioning device selects to operate at the maximum frequency of the preset resonance frequency range, the air volume output by the air conditioning device will be reduced by reducing the fan speed required for the operation of the air conditioning device. The reduction of the air volume can avoid the problem that the air conditioning device outputs too much cooling capacity when operating at the maximum frequency, so that the indoor environmental temperature can exactly reach the target temperature. If the air conditioning device selects to operate at the minimum frequency of the preset resonance frequency range, the air volume output by the air conditioning device will be increased by increasing the fan speed required for the operation of the air conditioning device. The increase of the air volume can avoid the problem that the air conditioning device outputs too little cooling capacity when operating at the minimum frequency, so that the indoor environmental temperature can reach the target temperature.

[0066] In addition, during the process of controlling the operation of the air conditioning device in the embodiment of the present application, there is no switching between the maximum frequency and the minimum frequency, so it can also avoid the impact on the service life of the compressor of the air conditioning device caused by frequent switching of the control frequency.

[0067] It can be seen that the embodiment of the present application solves the technical problem of poor control effect on the air conditioning device when the control frequency of the air conditioning device is within the resonance frequency range, and improves the control effect on the air conditioning device by combining the adjustment of the fan speed.

[0068] In a possible implementation manner, step S30: According to the control frequency and the fan speed, determine the target fan speed corresponding to the target control frequency, includes:

[0069] Step S31, according to the control frequency and the fan speed, obtain the cooling capacity corresponding to the control frequency and the fan speed;

[0070] As an example, the historical control frequency, historical fan speed, and historical cooling capacity of the air conditioning device can be used in advance as training samples to construct a cooling capacity model. Thus, when obtaining the cooling capacity corresponding to the control frequency and fan speed based on the control frequency and fan speed, the control frequency and fan speed can be used as the input of the cooling capacity model to calculate the cooling capacity corresponding to the control frequency and fan speed through this cooling capacity model. As another example, a cooling capacity configuration table for recording the cooling capacity corresponding to different control frequencies and fan speeds can be configured in advance. Thus, when obtaining the cooling capacity corresponding to the control frequency and fan speed based on the control frequency and fan speed, the control frequency and fan speed are used as index conditions to look up the corresponding cooling capacity in the preset cooling capacity configuration table. The determination method of the cooling capacity corresponding to the control frequency and fan speed in this example is not specifically limited.

[0071] Step S32: Determine the fan speed corresponding to the cooling capacity and the target control frequency as the target fan speed according to the cooling capacity and the target control frequency.

[0072] As an example, the historical cooling capacity, historical target control frequency, and historical target fan speed of the air conditioning device can be used in advance as training samples to construct a fan speed model. Thus, when determining the target fan speed corresponding to the cooling capacity and the target control frequency based on the cooling capacity and the target control frequency, the cooling capacity and the target control frequency can be used as the input of the fan speed model to calculate the corresponding target fan speed through this fan speed model.

[0073] As another example, a fan speed configuration table for recording the target fan speed corresponding to different cooling capacities and target control frequencies can be configured in advance. Thus, when determining the target fan speed corresponding to the cooling capacity and the target control frequency based on the cooling capacity and the target control frequency, the cooling capacity and the target control frequency are used as index conditions to look up the corresponding target fan speed in the preset fan speed configuration table. The determination method of the target fan speed corresponding to the cooling capacity and the target control frequency in this example is not specifically limited.

[0074] In this embodiment, first, according to the control frequency and fan speed that the air conditioning device needs to operate, determine the cooling capacity that the air conditioning device needs to output so that the indoor environmental temperature can reach the target temperature. Then, according to this cooling capacity and the target control frequency that the air conditioning device will actually operate, determine the target fan speed that the air conditioning device should actually operate so that the air conditioning device can still output this cooling capacity after changing the control frequency of the air conditioning device.

[0075] Therefore, in this embodiment, the cooling capacity is used to adjust the fan speed required for the operation of the air conditioning device, so that the air conditioning device can obtain the same control effect as the control frequency operating within the resonance frequency range, improving the control effect of the air conditioning device.

[0076] In another possible implementation manner, the control method of the air conditioning device further includes:

[0077] Step S33, when there is no fan speed corresponding to the cooling capacity and the target control frequency, use the cooling capacity range obtained by offsetting the cooling capacity by a preset threshold as the target cooling capacity;

[0078] Step S34, determine the fan speed corresponding to the target cooling capacity and the target control frequency according to the target cooling capacity and the target control frequency, and use it as the target fan speed.

[0079] It should be noted that if there is also no corresponding fan speed for the target cooling capacity obtained after offsetting the cooling capacity by the preset threshold, the offset can also be continued for the target cooling capacity obtained after offsetting until the target fan speed is obtained.

[0080] In this embodiment, when there is no fan speed corresponding to the cooling capacity and the target control frequency, it means that the fan speed corresponding to this cooling capacity and the target control frequency may be a fan speed at which the air conditioning device cannot operate, or it may be that the fan speed corresponding to this cooling capacity and the target control frequency has not been pre-configured, resulting in the inability to determine the corresponding fan speed. At this time, it is necessary to make a certain adjustment to the cooling capacity. The cooling capacity obtained by offsetting the cooling capacity by the preset threshold can be used as the target cooling capacity, so that the corresponding target fan speed can be determined according to the target cooling capacity and the target control frequency later, so that the air conditioning device can obtain a control effect approximately the same as the control frequency operating within the resonance frequency range.

[0081] In a possible implementation manner, the step S20: when the control frequency of the air conditioning device is within the preset resonance frequency range, determine the maximum frequency or the minimum frequency of the preset resonance frequency range as the target control frequency, includes:

[0082] Step S21, when the control frequency of the air conditioning device is within the preset resonance frequency range, determine the smaller value of the difference between the control frequency and the maximum frequency and the difference between the control frequency and the minimum frequency;

[0083] Step S22, when the difference between the control frequency and the maximum frequency is small, use the maximum frequency as the target control frequency;

[0084] It can be understood that if the difference between the control frequency and the maximum frequency is small, it indicates that the control frequency is closer to the maximum frequency at this time, and the maximum frequency can be used as the target control frequency.

[0085] Step S23, when the difference between the control frequency and the minimum frequency is small, use the minimum frequency as the target control frequency.

[0086] It can be understood that if the difference between the control frequency and the minimum frequency is small, it indicates that the control frequency is closer to the minimum frequency at this time, and the minimum frequency can be used as the target control frequency.

[0087] In this embodiment, the target control frequency is determined by determining the smaller value between the difference between the control frequency and the maximum frequency and the difference between the control frequency and the minimum frequency, that is, determining the frequency that the air conditioning device will actually use at the current moment. Since the determined target control frequency is the frequency closest to the control frequency among the maximum frequency and the minimum frequency, when using this target control frequency to control the air conditioning device, it is more conducive to enabling the air conditioning device to obtain the same control effect as when operating at a control frequency within the resonance frequency range.

[0088] In addition, if the maximum frequency is used as the target control frequency, the indoor environmental temperature can reach the target temperature relatively quickly, thereby improving the user experience; if the minimum frequency is used as the target control frequency, the power consumption of the air conditioning device can be reduced, thereby achieving an energy-saving effect.

[0089] In a possible implementation manner, the control method of the air conditioning device further includes:

[0090] Step S101, when the control frequency of the air conditioning device is outside the preset resonance frequency range, operate according to the obtained control frequency and fan speed.

[0091] It can be understood that when the control frequency of the air conditioning device is outside the preset resonance frequency range, it indicates that the frequency and fan speed that the air conditioning device needs to use for operation at this time, and the air conditioning device can be normally controlled to operate according to the frequency and fan speed that need to be used.

[0092] In a possible implementation manner, the control method of the air conditioning device further includes:

[0093] Step S50, after the air conditioning device operates for a preset time, return to execute the step of obtaining the control frequency and fan speed of the air conditioning device.

[0094] It should be noted that the preset time is used to ensure the safe operation of the air conditioning device.

[0095] In this embodiment, after the air conditioning device operates for a preset time, it will return to execute the step of obtaining the control frequency and the fan speed of the air conditioning device again. That is to say, in this embodiment, the method of obtaining the control frequency and the fan speed of the air conditioning device is a periodic acquisition method, so as to achieve periodic control of the operation of the air conditioning device, thereby avoiding the risk of interrupting the operation of the air conditioning device when the control frequency of the currently operating air conditioning device is within the preset resonance frequency range, and ensuring the operation stability and safety of the air conditioning device.

[0096] In a possible implementation manner, the step S10: obtaining the control frequency and the fan speed of the air conditioning device includes:

[0097] Step A11, obtaining the current ambient temperature;

[0098] It should be noted that the ambient temperature refers to the temperature of the environment where the air conditioning device is located, and the current ambient temperature refers to the temperature of the environment where the air conditioning device is currently located.

[0099] Step A12, based on a preset PID control parameter relationship table, obtaining the PID control frequency and the PID fan speed corresponding to the current ambient temperature as the control frequency and the fan speed of the air conditioning device.

[0100] It should be noted that the PID (temperature P, temperature I, temperature D) control parameter relationship table is used to represent the mapping relationship between different ambient temperatures and the PID control frequency and the PID fan speed. The control parameters are used to represent the relevant parameters for controlling the operation of the air conditioning device, and the control parameters may include the operating frequency, the fan wind speed, etc. When obtaining the PID control frequency and the PID fan speed corresponding to the current ambient temperature based on the preset PID control parameter relationship table, in fact, the current ambient temperature is mapped in the preset PID control parameter relationship table, and the mapped PID control frequency and the PID fan speed are the PID control frequency and the PID fan speed corresponding to the current ambient temperature.

[0101] In this embodiment, first, the current ambient temperature is obtained. Then, based on a preset PID control parameter relationship table, the PID control frequency and the PID fan speed corresponding to the current ambient temperature are obtained. The PID control frequency is used as the control frequency of the air conditioning device, and the PID fan speed is used as the fan speed of the air conditioning device. Thus, in this embodiment, by presetting the PID control parameter relationship table for characterizing the mapping relationship between different ambient temperatures and the PID control frequency and the PID fan speed, when obtaining the control frequency and the fan speed of the air conditioning device, the control frequency and the fan speed of the air conditioning device can be quickly mapped from the PID control parameter relationship table directly through the current ambient temperature, so as to improve the obtaining efficiency of the control frequency and the fan speed of the air conditioning device.

[0102] In another possible implementation manner, step S10: obtaining the control frequency and the fan speed of the air conditioning device includes:

[0103] Step B11, obtaining at least two of the current ambient parameters, operating parameters, and set parameters;

[0104] It should be noted that the ambient parameter refers to the parameter of the environment where the air conditioning device is located, the current ambient parameter refers to the parameter of the environment where the air conditioning device is currently located, and the ambient parameter may include ambient temperature, ambient humidity, etc. The operating parameter is the operating parameter of the air conditioning device, and the operating parameter may include operating frequency, fan speed, operating power, operating time, etc. The set parameter is the operating parameter set for the air conditioning device.

[0105] Step B12, using the obtained parameters as inputs based on a preset control parameter model, and calculating the control frequency and the fan speed of the air conditioning device.

[0106] It should be noted that the control parameter model is used to predict and calculate the control frequency and the fan speed by combining the actually input parameters. The control parameter model can be obtained through training with historical parameters, and the historical parameters may include historical ambient parameters, historical operating parameters, and historical set parameters.

[0107] In this embodiment, by obtaining at least two of the current ambient parameters, operating parameters, and set parameters, the obtained parameters are used as inputs to the preset control parameter model, and the control frequency and the fan speed of the air conditioning device are calculated through the control parameter model.

[0108] Therefore, in this embodiment, the control frequency and the fan speed of the air conditioning device are determined by combining the actual situation through the control parameter model. Compared with the embodiment using the PID control parameter relationship table for determination, although the obtaining efficiency is relatively low, the accuracy of the control frequency and the fan speed of the air conditioning device obtained is relatively high.

[0109] Exemplarily, for the purpose of facilitating the understanding of the technical concept or principle of the present application, please refer to Figure 3 , Figure 3 A brief flowchart of the control method for the air conditioning equipment of the present application is provided. Taking the preset resonance frequency range including the upper boundary frequency and the lower boundary frequency as an example, it is specifically as follows:

[0110] At every certain time interval T (corresponding to the above-mentioned preset time), the recommended frequency Fr (corresponding to the above-mentioned control frequency) and the fan speed Wr for using the air conditioning equipment are obtained, and then it is determined whether the frequency Fr is in the resonance region (corresponding to the above-mentioned preset resonance frequency range). If it is determined that the frequency Fr is outside the resonance region, the air conditioning equipment is controlled to operate according to the frequency Fr and the fan speed Wr; if it is determined that the frequency Fr is in the resonance region, the upper boundary frequency Fh of the resonance region can be selected as the target control frequency, or the lower boundary frequency Fl of the resonance region can be selected as the target control frequency; then, the refrigerating capacity Q is determined through the target control frequency and the fan speed; then, on the premise that the refrigerating capacity Q remains unchanged or is close, the target fan speed corresponding to the target control frequency is determined; finally, the air conditioning equipment is controlled to operate according to the target control frequency and the target fan speed, so that the air conditioning equipment can achieve the same control effect as the operating frequency Fr and the fan speed Wr.
