If the next cycle is reached, the air conditioner runs at the target operating frequency in the next cycle. The temperature difference model of the current cycle can predict the temperature difference data at a future time.

Therefore, the operating frequency can be pre-adjusted.

[0059] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] This application provides an air conditioning operation method, apparatus, electronic device, and computer-readable storage medium. Specifically, this application provides an air conditioning operation apparatus suitable for electronic devices, wherein the electronic device is primarily designed for air conditioning.

[0061] Please see Figure 1 Taking the air conditioner's operation method as an example, the specific execution process is as follows:

[0062] When the air conditioner 10 is running, the running time of the air conditioner 10 is divided into multiple cycles. For each cycle, the temperature difference change data of the air conditioner 10 when running at the current operating frequency in the current cycle is recorded, and the corresponding current temperature difference model is obtained by fitting the temperature difference change data.

[0063] Next, using the current temperature difference model, the predicted temperature difference data of the air conditioner 10 at the target time after the current cycle is predicted to be running at the current operating frequency. If the predicted temperature difference data is less than the corresponding temperature difference threshold, the current operating frequency is adjusted down according to the preset frequency difference value to obtain the target operating frequency. When the next cycle after the current cycle is reached, the air conditioner 10 is run at the target operating frequency.

[0064] In this embodiment, a current temperature difference model is fitted based on the temperature difference change data of the air conditioner running at the current operating frequency in the current cycle. Then, based on the current temperature difference model, the predicted temperature difference data of the air conditioner running at the current operating frequency at a target time after the current cycle is predicted. If the predicted temperature difference data is less than the temperature difference threshold, the current operating frequency is adjusted down by a preset frequency difference value to obtain the target operating frequency. If the next cycle is reached, the air conditioner runs at the target operating frequency in the next cycle. The temperature difference model of the current cycle can predict the temperature difference data at a future time. Based on the predicted temperature difference data, it can be determined whether the current operating frequency can meet the cooling effect in the future. Therefore, the operating frequency can be pre-adjusted. When the next cycle is reached, the air conditioner can run based on the adjusted frequency, realizing the pre-adjustment of the air conditioner frequency. Compared with the related technology of adjusting based on temperature difference after the operation ends, this solution can solve the problem of frequency adjustment lag. It does not need to wait for the next cycle to be executed before adjustment; the operating frequency of the air conditioner can be pre-adjusted before the next cycle is executed.

[0065] The following sections provide detailed descriptions of each example. It should be noted that the order in which the embodiments are described is not intended to limit the priority of the embodiments.

[0066] Please see Figure 2 , Figure 2 This is a flowchart illustrating an air conditioning operation method provided in an embodiment of this application. The specific flow of the air conditioning operation method is as follows:

[0067] 101. Based on the temperature difference change data of the air conditioner running at the current operating frequency in the current cycle, a current temperature difference model is fitted.

[0068] In this embodiment of the application, the operation cycle of the air conditioner is divided by the interval of the operation time. For example, the operation time corresponding to each cycle can be the same or different, and the size of the time interval of each cycle can be set according to actual needs. Here, the specific size of the time interval is not limited.

[0069] The operating frequency of an air conditioner mainly refers to the operating frequency of the air conditioner compressor. This operating frequency affects the cooling effect of the air conditioner. A higher operating frequency can accelerate the cooling process, but when the frequency is too high, it will also increase the energy consumption and cause waste of resources.

[0070] It should be noted that the temperature difference data refers to the temperature difference data at various times within the current cycle. This temperature difference data is calculated based on the temperature data detected by the temperature sensor after the air conditioner starts running. For example, the temperature difference data can be obtained from the difference between the current temperature of the air conditioner and the set temperature. The current temperature of the air conditioner is the temperature of the environment or space where the air conditioner is located, such as the room temperature of the room where the air conditioner is located; the set temperature of the air conditioner is the desired temperature set by the user, such as the desired indoor temperature obtained by the user after adjusting the air conditioner using the air conditioner remote control.

[0071] In this embodiment, a corresponding temperature difference model, also known as a temperature difference change curve, is obtained by fitting the temperature difference data at each time point using linear regression. Based on this temperature difference model, the temperature difference data at a future time point can be predicted. For example, based on the temperature difference data at each time point in the current cycle, a current temperature difference model corresponding to the current cycle is obtained by fitting the model using linear regression. This current temperature difference model is then used to predict the temperature difference data at a target time point after the current cycle.

[0072] 102. Based on the current temperature difference model, predict the predicted temperature difference data of the air conditioner when it is running at the current operating frequency at a target time, wherein the target time is after the current cycle.

[0073] The current temperature difference model, which is obtained by fitting the temperature difference data of the current cycle, can predict the temperature data for a period of time after the current cycle. Therefore, the current temperature difference model can be used to predict the temperature difference data at the target time after the current cycle, and the predicted temperature difference data at the target time can be obtained.

[0074] In this embodiment of the application, when the time difference between the target time and the current period is large, the accuracy of the current temperature difference model can be improved by increasing the time length of the current period, thereby improving the accuracy of the predicted temperature difference data at the target time.

[0075] 103. If the predicted temperature difference data is less than the temperature difference threshold, the current operating frequency is adjusted down according to the preset frequency difference to obtain the target operating frequency.

[0076] It should be noted that in the embodiments of this application, the target time is a relative time, which is a time that is a time difference from a certain point in time, such as the tenth minute, the twentieth minute or the thirtieth minute after powering on.

[0077] It should be noted that the temperature difference threshold is the expected temperature difference value at the target time. This temperature difference threshold can be predefined according to the actual cooling needs. For example, after the user sets the desired temperature of the air conditioner, the temperature difference value at the target time can be determined based on this desired temperature. For instance, based on the user's set desired temperature, the air conditioner is required to reach a temperature difference threshold A within ten minutes after being turned on. In this embodiment, the temperature difference threshold at the target time can be determined based on the correspondence between the air conditioner's set temperature, the target time, and the temperature difference threshold.

[0078] In this embodiment of the application, when the predicted temperature difference data is less than the temperature difference threshold, it means that when the air conditioner runs at the current operating frequency to the target time, it can meet the expected cooling effect. In this embodiment of the application, by reducing the operating frequency of the air conditioner, it is expected that the air conditioner can reduce the power consumption of the air conditioner while meeting the cooling requirements.

[0079] In this embodiment of the application, the preset frequency difference is a pre-set difference value, which corresponds to the magnitude of the reduction in the air conditioner's operating frequency. It should be noted that in this embodiment of the application, the difference value can be a fixed value set in advance based on empirical parameters.

[0080] However, in actual control, the specific value corresponding to the preset frequency difference can also be dynamically adjusted based on the difference between the predicted temperature difference data and the temperature difference threshold, resulting in a real-time dynamically adjusted frequency difference. For example, when the difference between the temperature difference threshold and the predicted temperature difference data is large, the specific value corresponding to the preset frequency difference can be appropriately increased to increase the magnitude of the current frequency reduction. Conversely, when the difference between the temperature difference threshold and the predicted temperature difference data is small, the specific value corresponding to the preset frequency difference can be appropriately decreased to reduce the magnitude of the current frequency reduction. Determining the specific value of the preset frequency difference dynamically ensures the accuracy of the adjustment, avoids over-adjustment due to excessive frequency adjustment, and guarantees the effectiveness of the adjustment.

[0081] 104. If the next cycle of the current cycle is reached, the air conditioner shall be operated at the target operating frequency in the next cycle of the current cycle.

[0082] Since the expected cooling effect can be achieved when the air conditioner is running at the current operating frequency in the current cycle, the energy consumption generated during the cooling process can be reduced by lowering the frequency in the next cycle while ensuring the cooling effect.

[0083] Accordingly, in this embodiment, the target operating frequency is obtained by adjusting the current operating frequency. Therefore, by operating the air conditioner in the next cycle of the current cycle at the target operating frequency, the need to reduce the power consumption generated by air conditioning cooling can be met while ensuring the cooling effect.

[0084] In this embodiment, a current temperature difference model is fitted based on the temperature difference change data of the air conditioner running at the current operating frequency in the current cycle. Then, based on the current temperature difference model, the predicted temperature difference data of the air conditioner running at the current operating frequency at a target time after the current cycle is predicted. If the predicted temperature difference data is less than the temperature difference threshold, the current operating frequency is adjusted down by a preset frequency difference value to obtain the target operating frequency. If the next cycle is reached, the air conditioner runs at the target operating frequency in the next cycle. The temperature difference model of the current cycle can predict the temperature difference data at a future time. Based on the predicted temperature difference data, it can be determined whether the current operating frequency can meet the cooling effect in the future. Therefore, the operating frequency can be pre-adjusted. When the next cycle is reached, the air conditioner can run based on the adjusted frequency, realizing the pre-adjustment of the air conditioner frequency. Compared with the related technology of adjusting based on temperature difference after the operation ends, this solution can solve the problem of frequency adjustment lag. It does not need to wait for the next cycle to be executed before adjustment; the operating frequency of the air conditioner can be pre-adjusted before the next cycle is executed.

[0085] Furthermore, in related technologies, the frequency adjustment of air conditioners relies on collected temperature data. Ideally, the collected temperature data reflects the cooling effect of the air conditioner, and the frequency is adjusted accordingly. However, the cooling effect of an air conditioner is affected by actual operating conditions, such as the set temperature, indoor temperature, outdoor temperature, fan speed, and the material and size of the building. Among these, the set temperature, indoor temperature, outdoor temperature, and fan speed are relatively easy to detect and the accuracy of the data can be guaranteed. However, the material and size of the building are not easy to detect, and it is difficult to guarantee the accuracy of the data obtained. Therefore, when adjusting the frequency based on the cooling effect, the judgment of the cooling effect has a certain error, which leads to a certain error in the frequency adjustment, making it difficult to guarantee the accuracy of the frequency adjustment.

[0086] The embodiments of this application define a model of temperature difference changing over time, which can reflect implicit factors such as building material and size in the current working condition data. This model is used to predict the temperature difference at the next time. By setting some parameters and comparing whether the expected temperature difference is achieved, feedback is then provided to adjust the frequency, so as to achieve an effect similar to having expert experience and automatic control.

[0087] In this embodiment of the application, after the air conditioner is operated at the target frequency in the next cycle of the current cycle, it can be determined whether the air conditioner can be further adjusted to reduce its frequency based on the temperature difference data corresponding to the next cycle. That is, optionally, in some embodiments of this application, after the step "if the next cycle of the current cycle is reached, then the air conditioner is operated at the target operating frequency in the next cycle of the current cycle", the method further includes:

[0088] The next period is the period following the current period.

[0089] The temperature difference model for the next week is obtained by fitting the temperature difference change data for the next cycle.

[0090] Based on the next week's temperature difference model, predict the next week's predicted temperature difference data when the air conditioner is running at the target operating frequency at the target time, wherein the target time is after the next cycle;

[0091] If the predicted temperature difference data for the following week is less than the temperature difference threshold, the target operating frequency is lowered according to the preset frequency difference value, and the air conditioner is operated in the next cycle after the next cycle according to the target operating frequency obtained after the lowering, until the next cycle is the preset end cycle.

[0092] In this solution, after the next cycle ends, it can be determined whether the expected cooling effect can be achieved by running at the target frequency in a manner similar to the current cycle. By making judgments in subsequent cycles, the operating frequency of the air conditioner can be adjusted before the execution of each subsequent cycle, thus achieving pre-adjustment of the operating frequency of each cycle. Compared with related technologies that adjust the operating frequency based on real-time temperature data after operation, this solution can adjust the operating frequency of the air conditioner in a timely manner, thereby achieving the effect of saving air conditioning energy.

[0093] In this embodiment of the application, to further determine whether the air conditioner can achieve the expected cooling effect when running at the current operating frequency, the temperature difference data of the previous cycle can also be used to assist in the judgment. That is, optionally, in some embodiments of this application, the step "if the predicted temperature difference data is less than the temperature difference threshold, then the current operating frequency is lowered according to the preset frequency difference value to obtain the target operating frequency" includes:

[0094] The period preceding the current period is taken as the previous period, and the period following the current period is taken as the next period.

[0095] Predict the first ending temperature difference data at the end of the next cycle based on the current temperature difference model;

[0096] The second ending temperature difference data at the end time is predicted based on the weekly temperature difference model corresponding to the previous cycle, wherein the weekly temperature difference model is obtained by fitting the weekly temperature difference change data of the previous cycle.

[0097] If the predicted temperature difference data is less than the temperature difference threshold, the difference between the second ending temperature difference data and the first ending temperature difference data satisfies the first preset condition, and the average value of the temperature difference change data of the previous week is greater than the average value of the temperature difference change data of the current period, then the current operating frequency is adjusted down according to the preset frequency difference to obtain the target operating frequency.

[0098] In this embodiment, the first ending temperature difference data is the temperature difference data at the end of the next cycle predicted by the current temperature difference model, and the second ending temperature difference data is the temperature difference data at the end of the next cycle predicted by the temperature difference model of the previous week. The ending time is the last moment of the cycle.

[0099] Specifically, by predicting the temperature difference data at the end of the next cycle and comparing it with this data, it can be further determined whether the air conditioner can achieve the expected cooling effect when operating at the current frequency. Furthermore, by using the current temperature difference model corresponding to the current cycle and the temperature difference model from the previous week to predict the temperature difference data at the end of the next cycle, and comparing the two prediction results, it can be further determined whether the air conditioner can achieve the expected cooling effect when operating at the current frequency. For example, when the temperature difference predicted by the temperature difference model from the previous week...

[0100] It should be noted that the first preset condition is a numerical condition, such as a specific value or range of values. When the second ending temperature difference data is greater than the first ending temperature difference data, it means that as time goes by, when running at the current operating frequency in the current cycle, the temperature difference is gradually decreasing compared to the previous cycle, which can meet the cooling requirements.

[0101] In addition, the average value of the temperature difference change last week is the average value of the temperature difference data at each moment in the previous cycle. If the average value of the temperature difference change data last week is greater than the average value of the temperature difference change data in the current cycle, it means that the air conditioner can achieve the cooling effect when running at the current operating frequency in the current cycle, that is, it indicates that the air conditioner is still continuously cooling.

[0102] Correspondingly, by judging multiple conditions, it can be determined whether the air conditioner can meet the continuous cooling demand at the current operating frequency. The judgment of multiple conditions improves the accuracy of the judgment result on whether cooling is required.

[0103] Since fitting and judging the temperature difference model in each cycle is costly, this embodiment of the application can define the stages of air conditioner operation. For example, please refer to... Figure 3 , Figure 3 This is a guide diagram of the various stages of air conditioner operation provided in the embodiments of this application. The stage where the operating frequency of the cycle is pre-adjusted is called the frequency pre-adjustment stage T1, and the next stage is the general adjustment stage T2. When the next stage is reached, the frequency can be adjusted according to the actual collected temperature to reduce the cost of air conditioner frequency adjustment and reduce resource consumption. Optionally, in some embodiments of this application, the step "If the predicted temperature difference data for the next week is less than the temperature difference threshold, then the target operating frequency is lowered according to the preset frequency difference value, and the air conditioner is operated according to the second target operating frequency obtained after the lowering in the next cycle until the next cycle is a preset end cycle" includes:

[0104] The frequency at which the air conditioner operates during the preset end period is used as the reference operating frequency;

[0105] A first reference time period after the preset end period and a second reference time period after the first reference time period are determined according to a preset time interval.

[0106] If the first reference time period is reached, the air conditioner will operate at the reference operating frequency.

[0107] At the end of the first reference time period, the reference operating frequency is adjusted according to the real-time temperature difference at the end of the first reference time period to obtain the adjusted reference operating frequency.

[0108] If the second reference time period is reached, the air conditioner will operate at the reference operating frequency during the second reference time period.

[0109] In this embodiment of the application, the first reference time period, the second reference time period, and the subsequent third or fourth reference time period can all be determined according to a preset time interval, and the time interval of each reference time period can be the same or different.

[0110] In this process, after the pre-adjustment phase of the cyclical operating frequency, the operating frequency at the end of the pre-adjustment phase can be used as the operating frequency for the next phase. Because of the pre-adjustment phase, the air conditioner's operating frequency is essentially close to the desired frequency, meaning that the operating frequency is reduced as much as possible while still meeting cooling requirements. Therefore, during subsequent operation, the air conditioner's operating frequency can be fine-tuned based on real-time temperature differences. Furthermore, by referencing the time period division in subsequent operating phases, the frequency of frequency adjustments can be reduced, thus lowering adjustment costs.

[0111] In this embodiment of the application, in each reference time period in the subsequent stages, the air conditioning operating frequency of the next reference time period can be determined based on the real-time temperature difference at the end of the previous reference time period.

[0112] In this embodiment, since the cooling demand required when the air conditioner is turned on is relatively large and the frequency is usually high, please refer to... Figure 3 As shown, before the frequency pre-adjustment stage T1, an initial start-up stage T0 can also be set, with the aim of quickly achieving temperature cooling adjustment through the initial start-up stage. That is, optionally, in some embodiments of this application, before the step "fitting the current temperature difference model based on the temperature difference change data of the air conditioner running at the current operating frequency in the current cycle", the method further includes:

[0113] In response to a power-on command, the system searches for a matching power-on frequency for the air conditioner under the current operating conditions. The matching power-on frequency is the desired power-on frequency of the air conditioner under the current operating conditions.

[0114] If the matching start-up frequency exists, the air conditioner is turned on according to the matching start-up frequency, and the air conditioner operates at the current stage according to the matching start-up frequency;

[0115] If the matching start-up frequency does not exist, then search for the historical start-up frequency of the air conditioner under the current operating conditions;

[0116] If the historical start-up frequency does not exist, the air conditioner is turned on at the current default start-up frequency and runs at the current stage according to the default start-up frequency. At the end of the current running stage, if the actual temperature difference at the end of the current running stage meets the second preset condition, the default start-up frequency is used as the historical start-up frequency of the air conditioner in the current operating condition.

[0117] If the historical start-up frequency exists, the historical start-up frequency is adjusted down according to another preset frequency difference to obtain a reference start-up frequency. The air conditioner is then turned on according to the reference start-up frequency and operated in the current stage according to the reference start-up frequency. When the current stage ends, if the actual temperature difference at the end of the current stage meets a second preset condition, the reference start-up frequency is used as the historical start-up frequency of the air conditioner in the current operating condition.

[0118] It should be noted that the matched power-on frequency is the power-on frequency that meets the expected power-on frequency under the current operating conditions, that is, the optimal power-on frequency under ideal conditions. This matched power-on frequency can be obtained through historical experiments or user-defined configuration.

[0119] When the air conditioner receives a power-on command, it first searches for a matching power-on frequency from the cloud or local storage. If the matching power-on frequency exists, the air conditioner is powered on directly at that frequency and operates accordingly. If the matching power-on frequency does not exist, it searches for a historical power-on frequency. If a historical power-on frequency exists, it is adjusted down by another preset frequency difference, and the air conditioner is powered on at the adjusted reference power-on frequency and operates accordingly. If the historical power-on frequency does not exist, the air conditioner is powered on at its current default frequency and operates accordingly.

[0120] It should be noted that, in this embodiment, when the air conditioner finishes operating in the current phase, the temperature difference data at the end of the current phase is detected. Based on this temperature difference data, it is determined whether to use the operating frequency of the current phase as the historical operating frequency for the next time the air conditioner is turned on. For example, when the air conditioner is running at the default operating frequency in the current phase, if the temperature difference data at the end of the current phase meets the conditions, then the default operating frequency is used as the historical operating frequency for the next time the air conditioner is turned on under the current operating conditions. When the air conditioner is running at the reference operating frequency in the current phase, if the temperature difference data at the end of the current phase meets the conditions, then the reference operating frequency is used as the historical operating frequency for the next time the air conditioner is turned on.

[0121] In this embodiment of the application, the second preset condition is a numerical condition, which may be a specific numerical value or a data range. The second preset condition may be the same as or different from the first preset condition, and the second preset condition may be based on a predefined value.

[0122] In some embodiments of this application, after the initial startup phase is completed, a frequency pre-adjustment phase can be performed. Specifically, in some embodiments of this application, the step "fitting the current temperature difference model based on the temperature difference change data of the air conditioner running at the current operating frequency in the current cycle" includes:

[0123] If the current cycle is the first cycle of the next stage of the current phase, then the historical start-up frequency of the air conditioner at the end of the current phase is taken as the current operating frequency of the current cycle.

[0124] The air conditioner is operated in the current cycle according to the current operating frequency to obtain temperature difference change data;

[0125] Based on the temperature difference change data, the current temperature difference model is obtained by fitting.

[0126] After the initial startup phase ends, the operating frequency of the initial startup phase can be used as the operating frequency of the first cycle of the frequency pre-adjustment phase. If the current cycle is the first cycle of the frequency pre-adjustment phase, then the operating frequency of the initial startup phase is directly used as the current operating frequency of the current cycle.

[0127] Specifically, by predicting and comparing the temperature difference data for the next cycle using temperature difference models from the previous and current cycles, and by comparing the average values ​​of temperature difference changes from the previous and current cycles, the cooling trend of the air conditioner can be comprehensively judged from multiple conditions, improving the accuracy of cooling judgment. Furthermore, by adding an initial start-up stage before the frequency pre-adjustment stage to accelerate cooling, and by adding a general adjustment stage after the frequency pre-adjustment stage, the operating frequency of the air conditioner can be adjusted according to temperature. Through the adjustment of the air conditioner frequency at each stage, the frequency regulation is smoother and better meets the cooling needs at different times.

[0128] Please see Figure 4 , Figure 4 This is a flowchart illustrating the initial start-up phase of the air conditioning operation method provided in this application embodiment, wherein the air conditioning operation method specifically includes:

[0129] 211. Use the remote control to turn on the air conditioner under the current operating conditions;

[0130] 212. Based on the current operating conditions, search the cloud or local air conditioner data for a matching start-up frequency. If a match is found, proceed to step 213; otherwise, proceed to step 214.

[0131] 213. Start the air conditioner according to the matched start-up frequency, and run the air conditioner during the initial start-up phase according to the matched start-up frequency. After the initial start-up phase is completed, proceed to step 219.

[0132] 214. Based on the current operating conditions, search the cloud or local air conditioner data for historical power-on frequencies. If they exist, proceed to step 215; otherwise, proceed to step 216.

[0133] 215. Based on the historical start-up frequency, reduce the first preset frequency difference, and start the air conditioner according to the reference start-up frequency obtained after the reduction, and run the air conditioner in the initial start-up stage according to the reference start-up frequency.

[0134] 216. Turn on the air conditioner at the current default start-up frequency, and run the air conditioner during the initial start-up phase according to the default start-up frequency. After the initial start-up phase is completed, proceed to step 219.

[0135] 217. At the end of the initial start-up phase, determine whether the initial start-up phase meets the cooling effect based on the real-time temperature difference at the end of the initial start-up phase. If it does, proceed to step 218.

[0136] 218. The operating frequency of the air conditioner during the initial startup phase shall be used as the historical startup frequency of the air conditioner when it is turned on again.

[0137] 219. The initial startup phase has ended.

[0138] It should be noted that the air conditioner operates at a higher frequency during the initial start-up phase, resulting in better cooling and faster cooling of the scene. However, due to the instability of the sensors and the unstable data in the first few minutes during the initial start-up phase, the curve cannot be accurately fitted. Therefore, after the air conditioner is turned on, it first enters the initial start-up phase and then enters the frequency pre-adjustment phase after a certain period of time.

[0139] It should also be noted that in this embodiment, the air conditioner goes through an initial start-up phase after being turned on. However, the number of times the historical start-up frequency is recorded after the initial start-up phase ends can be set to an upper limit, that is, only the historical start-up frequency after a certain number of initial start-up phases is remembered. The initial start-up phase is a learning process that continuously attempts to lower the frequency a limited number of times under the condition of achieving the expected cooling. If the optimal start-up frequency can be learned, the energy consumption in the first phase can be reduced.

[0140] After the initial startup phase is completed, the system enters the frequency pre-adjustment phase, and the operating frequency of the initial startup phase is used as the operating frequency for the first cycle of the frequency pre-adjustment phase. For details, please refer to [link to relevant documentation]. Figure 5 , Figure 5 This is a flowchart illustrating the frequency pre-adjustment stage in the air conditioning operation method provided in this application embodiment. The specific process of the frequency pre-adjustment stage is as follows:

[0141] 221. At the end of the initial start-up phase, the frequency pre-adjustment phase begins, and the operating frequency of the initial start-up phase is taken as the first operating frequency of the first operating cycle of the frequency pre-adjustment phase.

[0142] 222. Take the first operating cycle of the frequency pre-adjustment stage as the current operating cycle, and take the first operating frequency as the current operating frequency;

[0143] 223. When the current operating cycle is reached, the air conditioner shall operate at the current operating frequency within the current operating cycle.

[0144] 224. Determine whether the current operating cycle is the last operating cycle of the frequency pre-adjustment stage. If yes, proceed to step 234; otherwise, proceed to step 225.

[0145] 225. At the end of the current operating cycle, obtain the current temperature difference change data of the air conditioner during the current operating cycle based on the current operating frequency;

[0146] 226. Fit the current temperature difference model based on the current temperature difference change data, and predict the current predicted temperature difference data at the end of the frequency pre-adjustment stage based on the current temperature difference model;

[0147] 227. Determine whether the frequency pre-adjustment stage of the air conditioner is being executed for the first time. If yes, proceed to step 228; otherwise, proceed to step 229.

[0148] 228. If the current predicted temperature difference data is less than the temperature difference threshold at the end of the frequency pre-adjustment stage, then proceed to step 232.

[0149] 229. Based on the current temperature difference model, predict the first ending temperature difference data at the end of the next operating cycle of the current operating cycle;

[0150] 230. Fit the temperature difference change data of the previous operating cycle to obtain the temperature difference model of the previous week, and predict the second ending temperature difference data of the next operating cycle at the end time based on the temperature difference model of the previous week.

[0151] It should be noted that if the current operating cycle is the first operating cycle of this frequency pre-adjustment phase, then the previous operating cycle of the current operating cycle is the last operating cycle of the previous frequency pre-adjustment phase. That is, in this case, the temperature difference model of the previous week of the current operating cycle is the same as the temperature difference model corresponding to the last operating cycle of the previous frequency pre-adjustment phase.

[0152] 231. If the current predicted temperature difference data is less than the temperature difference threshold at the end of the frequency pre-adjustment stage, the difference between the second end temperature difference data and the first end temperature difference data meets the preset conditions, and the average value of the temperature difference change data of the previous operating cycle of the current operating cycle is greater than the average value of the temperature difference change data of the current operating cycle, then proceed to step 232.

[0153] 232. Based on the current operating frequency, reduce the second preset frequency difference to obtain the target operating frequency;

[0154] 233. Take the next running cycle of the current running cycle as the current running cycle, and take the target running frequency as the current running frequency, then return to step 223.

[0155] 234. The frequency pre-adjustment phase has ended.

[0156] The frequency pre-adjustment stage allows the air conditioner to predict the cooling effect of the operating cycle before it starts, and adjust the operating frequency of the operating cycle in advance based on the cooling effect. This ensures that each operating cycle runs at the adjusted operating frequency. Compared to related technologies that adjust the operating frequency of the next operating cycle based on the temperature difference after the current operating cycle is completed, this embodiment can adjust the operating frequency of the upcoming operating cycle in advance, solving the problem of lag in air conditioner frequency adjustment and improving the user experience.

[0157] In this embodiment, if the air conditioner is still in a state requiring operation after the frequency pre-adjustment phase of the air conditioner has ended, it enters the general adjustment phase. Please refer to [link to relevant documentation]. Figure 6 , Figure 6 This is a flowchart illustrating the general adjustment phase of the air conditioning operation method provided in this application embodiment. The specific process of this general adjustment phase is as follows:

[0158] 241. When the frequency pre-adjustment phase ends, the general adjustment phase begins, and the operating frequency of the last operating cycle of the frequency pre-adjustment phase is used as the reference operating frequency of the first reference time cycle of the general adjustment phase.

[0159] 242. Use this first reference time period as the current reference time period;

[0160] 243. If the current reference time period is reached, the air conditioner shall be operated at the reference operating frequency during the current reference time period, and real-time temperature difference data shall be collected at the end of the current reference time period.

[0161] 244. Determine whether the current reference time period is the last reference time period. If yes, proceed to step 247; otherwise, proceed to step 245.

[0162] 245. Adjust the base operating frequency based on the real-time temperature difference data to obtain the reference operating frequency;

[0163] 246. Take the next reference time period of the current reference time period as the current reference time period, and take the reference operating frequency as the base operating frequency of the current reference time period. Return to step 243 until the next reference time period is the last reference time period of the general adjustment phase.

[0164] 247. The general survey phase has ended.

[0165] In this embodiment of the application, the reference time period is divided according to the time interval. When the air conditioner stops running at the end of the first reference time period, there is no subsequent reference time period.

[0166] It should be noted that after the air conditioner goes through the initial start-up stage and the frequency pre-adjustment stage, the operating frequency of the air conditioner is close to the ideal value. This means that while ensuring the cooling effect, it can also minimize power consumption. Therefore, in the general adjustment stage, the time interval of each reference time period can be lengthened as much as possible to reduce the frequency of calculation and frequency adjustment, thereby reducing the computational burden and resource consumption.

[0167] In this embodiment of the application, after the air conditioner is started and running, it goes through the initial start-up stage, the frequency pre-adjustment stage and the general adjustment stage in sequence, so that the air conditioner can gradually achieve the cooling effect while meeting the minimum optimal frequency state, thereby saving the power consumption required for the operation of the air conditioner.

[0168] Please see Figure 7 , Figure 7 This is a schematic diagram of the air conditioner frequency change during operation, provided in an embodiment of this application. Curve A represents the temperature difference over time, curve B represents the operating frequency of a traditional air conditioner compressor over time, and curve C represents the operating frequency of the air conditioner compressor over time in this embodiment. In this embodiment, after the air conditioner is turned on, it first enters the initial start-up stage, operating at the optimal start-up frequency (matching the start-up frequency or a historical start-up frequency obtained after a certain number of adjustments) to achieve a certain cooling effect. Then, it enters the frequency pre-adjustment stage. In this pre-adjustment stage, while maintaining the cooling effect, the frequency is continuously reduced with a period of t, thus achieving energy saving through frequency regulation. Figure 7 As shown, the air conditioner is turned on at 15:23:20. Then, it runs at the optimal start-up frequency of 70 during the initial start-up phase. After that, at 15:30:00, it enters the frequency pre-adjustment phase, continuously trying to lower the air conditioner's operating frequency with t as the operating cycle.

[0169] Accordingly, please refer to Figure 8 , Figure 8 This is a schematic diagram of the temperature data changes of several indicators of the air conditioner during the operation of the air conditioner, provided in the embodiment of this application. The horizontal axis represents the time point, and the vertical axis represents the temperature data. The data is the temperature data within the last five minutes. Specifically, the temperature data of several indicators includes the set temperature, inner ring temperature, inner pipe temperature, outer ring temperature, and outer pipe temperature.

[0170] Accordingly, please refer to Figure 9 , Figure 9 This embodiment of the application shows a temperature difference change curve obtained by fitting temperature difference data after the air conditioner is turned on. The horizontal axis represents the nth second after the unit is turned on, and the vertical axis represents the temperature difference value. Specifically, a temperature difference change curve is obtained after fitting for each operating cycle of the frequency pre-adjustment stage.

[0171] To facilitate better implementation of the air conditioning operation method of this application, this application also provides an air conditioning operation device based on the above-described air conditioning operation method. The meanings of the terms used are the same as in the above-described air conditioning operation method, and specific implementation details can be found in the descriptions of the method embodiments.

[0172] Please see Figure 10 , Figure 10 This is a schematic diagram of the structure of the air conditioning operating device provided in the embodiment of this application, wherein the air conditioning operating device can be specifically as follows:

[0187] In some embodiments of this application, the device further includes a frequency converter control module, which includes:

[0188] The third determining unit is used to take the frequency at which the air conditioner operates during the preset end period as the reference operating frequency.

[0189] The fourth determining unit is used to determine a first reference time period after the preset end period and a second reference time period after the first reference time period according to a preset time interval.

[0190] A reference operating unit is configured to operate the air conditioner at the reference operating frequency if the first reference time period is reached.

[0191] A reference adjustment unit is used to adjust the reference operating frequency based on the real-time temperature difference at the end of the first reference time period to obtain the adjusted reference operating frequency.

[0192] A reference operating unit is configured to operate the air conditioner at the reference operating frequency during the second reference time period if the second reference time period is reached.

[0193] In some embodiments of this application, the device further includes an initial startup module, which includes:

[0194] The first search unit is used to search for a matching start-up frequency of the air conditioner under the current operating condition in response to a start-up command. The matching start-up frequency is the expected start-up frequency of the air conditioner under the current operating condition.

[0195] The second search unit is used to search for the historical operating frequencies of the air conditioner under the current operating conditions if the matching start-up frequency does not exist.

[0196] The down-adjustment unit is used to, if the historical power-on frequency exists, down-adjust the historical power-on frequency according to another preset frequency difference to obtain a reference power-on frequency;

[0197] The reference operation unit is used to turn on the air conditioner according to the reference start-up frequency, and to operate the air conditioner in the current stage according to the reference start-up frequency. When the current stage ends, if the actual temperature difference at the end of the current stage meets the second preset condition, the reference start-up frequency is used as the historical start-up frequency of the air conditioner in the current operating condition.

[0198] In some embodiments of this application, the initial startup module further includes:

[0199] A matching operation unit is configured to, if the matching start-up frequency exists, start the air conditioner according to the matching start-up frequency, and operate the air conditioner at the current stage according to the matching start-up frequency;

[0200] The default operating unit is configured to turn on the air conditioner at the current default operating frequency if the historical operating frequency does not exist, and to operate the air conditioner at the current stage according to the default operating frequency. If the actual temperature difference at the end of the current operating stage meets the second preset condition, the default operating frequency is used as the historical operating frequency of the air conditioner under the current operating condition.

[0201] In some embodiments of this application, the fitting module 301 includes:

[0205] In this embodiment, the fitting module 301 fits the temperature difference model based on the temperature difference change data of the air conditioner running at the current operating frequency in the current cycle. Then, the prediction module 302 predicts the predicted temperature difference data of the air conditioner running at the current operating frequency at a target time based on the current temperature difference model. The target time is after the current cycle. Subsequently, if the predicted temperature difference data is less than the temperature difference threshold, the adjustment module 303 adjusts the current operating frequency down by a preset frequency difference value to obtain the target operating frequency. Then, if the next cycle of the current cycle is reached, the running module 304 runs the air conditioner at the target operating frequency in the next cycle of the current cycle.

[0206] In this embodiment, the temperature difference model of the current cycle can predict the temperature difference data at a certain point in the future. Based on the predicted temperature difference data, it can be determined whether the current operating frequency can meet the cooling effect in the future. Therefore, the operating frequency can be pre-adjusted. When the next cycle is reached, the air conditioner can be run based on the adjusted frequency to achieve pre-adjustment of the air conditioner frequency. Compared with the method of adjusting based on the temperature difference after the operation is completed in related technologies, this solution can solve the problem of frequency adjustment lag. It does not need to wait for the next cycle to be executed before adjustment. The operating frequency of the air conditioner can be pre-adjusted before the next cycle is executed.

[0215] This application embodiment uses temperature difference change data of the air conditioner running at the current operating frequency in the current cycle to fit a current temperature difference model. Then, based on the current temperature difference model, it predicts the predicted temperature difference data of the air conditioner running at the current operating frequency at a target time after the current cycle. If the predicted temperature difference data is less than the temperature difference threshold, the current operating frequency is adjusted down by a preset frequency difference value to obtain the target operating frequency.
