Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically to an air conditioning compressor frequency control method, device, air conditioner, and storage medium. Background Technology

[0002] With the development of air conditioning technology, the use of inverter air conditioners has become increasingly widespread. Inverter air conditioners mainly achieve energy saving by controlling the frequency of the compressor during the air conditioner's operation.

[0003] In related technologies, variable frequency air conditioners mainly adjust the compressor frequency based on real-time detected indoor temperature and preset frequency control logic to meet the requirement of outdoor temperature reaching the set temperature. However, the preset frequency control logic is generally obtained from laboratory tests. Due to the diversity of air conditioner installation environments, there are still some differences between the actual installation environment and the laboratory environment. In addition, there is a lag in real-time temperature acquisition. Therefore, in actual use, controlling the compressor frequency of the air conditioner according to the preset frequency control logic will cause the temperature control of the variable frequency air conditioner to lag, repeatedly adjusting the operating frequency, resulting in increased air conditioner energy consumption. Summary of the Invention

[0004] This application provides a method, device, air conditioner, and storage medium for controlling the frequency of an air conditioner compressor, aiming to solve the problem of increased energy consumption caused by the lag in temperature control and repeated adjustment of the operating frequency in variable frequency air conditioners.

[0005] In a first aspect, this application provides a method for controlling the frequency of an air conditioning compressor, comprising:

[0006] When the air conditioner is detected to be working, the target elastic temperature difference between the indoor temperature of the environment where the air conditioner is located and the set temperature of the air conditioner is obtained, as well as the target working time corresponding to the target elastic temperature difference.

[0007] The first indoor temperature of the air conditioner within a first preset working time is obtained, and the first predicted working time corresponding to the target elastic temperature difference is predicted based on the temperature difference change information between the first indoor temperature and the set temperature.

[0008] If the first predicted working time is not equal to the target working time, then the compressor frequency of the air conditioner is adjusted.

[0009] In one embodiment of this application, obtaining the first indoor temperature of the air conditioner within a preset working time, and predicting the first predicted working time corresponding to the target elastic temperature difference based on the temperature difference change information between the first indoor temperature and the set temperature, includes:

[0010] The first indoor temperature is collected within a first preset working time according to the preset temperature collection frequency;

[0011] Calculate the temperature difference between each of the first indoor temperatures and the set temperature of the air conditioner. Based on each temperature difference and the acquisition time of the indoor temperature corresponding to each temperature difference, generate a prediction function. The prediction function is used to predict the duration of work based on the temperature difference.

[0012] The target elastic temperature difference is input into the prediction function, and the first predicted work duration corresponding to the target elastic temperature difference is output.

[0013] In one embodiment of this application, the step of adjusting the compressor frequency of the air conditioner if the first predicted work duration is not equal to the target work duration includes:

[0014] If the first predicted working time is less than the target working time, then reduce the compressor frequency of the air conditioner;

[0015] If the first predicted working time is greater than the target working time, then the compressor frequency of the air conditioner is increased.

[0016] In one embodiment of this application, the step of adjusting the compressor frequency of the air conditioner if the first predicted work duration is not equal to the target work duration includes:

[0017] If the first predicted work duration is not equal to the target work duration, then calculate the target duration difference between the first predicted work duration and the target work duration;

[0018] Find the preset mapping table corresponding to the duration difference and the adjustment frequency, and obtain the target adjustment frequency corresponding to the target duration difference;

[0019] The compressor frequency of the air conditioner is adjusted according to the target frequency adjustment control.

[0020] In one embodiment of this application, when the air conditioner is detected to be performing work, acquiring the target elastic temperature difference between the indoor temperature of the environment where the air conditioner is located and the set temperature of the air conditioner, and the target work duration corresponding to the target elastic temperature difference, includes:

[0021] When the air conditioner is detected to be working, the user's biological information corresponding to the environment in which the air conditioner is located is collected.

[0022] Based on the user's biometric information, identify the target user corresponding to the environment in which the air conditioner is located;

[0023] Based on the working parameters corresponding to the air conditioner's work, the corresponding user database of the target user is searched to obtain the target elastic temperature difference between the indoor temperature and the set temperature, as well as the target working time corresponding to the target elastic temperature difference.

[0024] In one embodiment of this application, the step of searching the user database corresponding to the target user based on the work parameters corresponding to the work performed by the air conditioner, and obtaining the target elastic temperature difference between the indoor temperature and the set temperature, and the target work duration corresponding to the target elastic temperature difference, includes:

[0025] Based on the working parameters corresponding to the air conditioner's work, search the user database corresponding to the target user;

[0026] If the target elastic temperature difference and target working time corresponding to the target user and the air conditioner working parameters are not found, a data acquisition command is fed back to obtain the target elastic temperature difference between the indoor temperature and the set temperature collected in response to the data acquisition command, as well as the target working time corresponding to the target elastic temperature difference.

[0027] In one embodiment of this application, after adjusting the compressor frequency of the air conditioner if the first predicted working time is not equal to the target working time, the method further includes:

[0028] Obtain the second indoor temperature of the environment where the air conditioner is located after the compressor frequency is adjusted;

[0029] Based on the temperature difference change information between the second indoor temperature and the set temperature of the air conditioner, and the temperature difference change information between the first indoor temperature and the set temperature of the air conditioner, the second predicted work duration corresponding to the target elastic temperature difference is predicted.

[0030] If the second predicted working time is not equal to the target working time, the compressor frequency of the air conditioner is adjusted.

[0031] Secondly, this application provides an air conditioner compressor frequency control device, the air conditioner compressor frequency control device comprising:

[0032] Acquisition module: used to acquire the target elastic temperature difference between the indoor temperature of the environment where the air conditioner is located and the set temperature of the air conditioner, and the target work duration corresponding to the target elastic temperature difference;

[0033] Duration prediction module: used to obtain the first indoor temperature of the air conditioner within a first preset working time, and predict the first predicted working time corresponding to the target elastic temperature difference based on the temperature difference change information between the first indoor temperature and the set temperature.

[0034] Adjustment module: used to control the compressor frequency of the air conditioner to adjust if the first predicted working time is not equal to the target working time.

[0035] Thirdly, this application provides an air conditioner, the air conditioner comprising:

[0036] One or more processors;

[0037] Memory; and

[0038] One or more applications, wherein the one or more applications are stored in the memory and configured to be executed by the processor to implement any one of the air conditioning compressor frequency control methods.

[0039] Fourthly, this application provides a computer-readable storage medium having a computer program stored thereon, the computer program being loaded by a processor to perform the steps in any of the air conditioning compressor frequency control methods described in the present application.

[0040] This application provides an air conditioner compressor frequency control method, device, air conditioner, and storage medium. When the air conditioner is detected to be performing work, a target elastic temperature difference between the indoor temperature of the environment where the air conditioner is located and the set temperature of the air conditioner, as well as a target work duration corresponding to the target elastic temperature difference, are obtained. A first indoor temperature within a first preset work duration is obtained, and a first predicted work duration corresponding to the target elastic temperature difference is predicted based on the temperature difference change information between the first indoor temperature and the set temperature. If the first predicted work duration is not equal to the target work duration, the compressor frequency of the air conditioner is controlled to be adjusted. This solution collects the elastic temperature difference and the target working time of the elastic temperature difference, as well as the first indoor temperature. Based on the temperature difference change information between the first indoor temperature and the set temperature of the air conditioner, it predicts the first predicted working time corresponding to the elastic temperature difference. That is, it predicts the working time of the air conditioner when the temperature difference between the indoor temperature and the set temperature reaches the elastic temperature difference by using the temperature difference change information between the indoor temperature and the set temperature. Then, it compares the predicted first working time with the collected target working time to evaluate whether the current working frequency of the compressor is reasonable. In addition, by obtaining the first target elastic temperature difference, the operating frequency of the compressor is evaluated, avoiding the impact of data transmission lag on the evaluation of the compressor frequency. If the first predicted working time is not equal to the target working time, it indicates that the compressor frequency is too high or too low. The compressor frequency is then adjusted to avoid the temperature control lag of the inverter air conditioner, repeated adjustment of the operating frequency, avoid waste of air conditioner work or insufficient temperature control (cooling or heating) capability, and improve the working performance of the air conditioner.

The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0053] This application provides an air conditioner compressor frequency control method, device, air conditioner, and computer-readable storage medium, which will be described in detail below.

[0054] The air conditioner compressor frequency control method in this embodiment of the invention is applied to an air conditioner compressor frequency control device. The air conditioner compressor frequency control device is installed in an air conditioner. The air conditioner is equipped with one or more processors, a memory, and one or more application programs. The one or more application programs are stored in the memory and configured to be executed by the processor to implement the air conditioner compressor frequency control method. The air conditioner can be a terminal, such as an indoor unit or an outdoor unit.

[0055] like Figure 1 As shown, Figure 1This is a schematic diagram of a scenario for an air conditioner compressor frequency control method according to an embodiment of this application. The air conditioner compressor frequency control scenario in this embodiment includes an air conditioner 100 (the air conditioner 100 integrates an air conditioner compressor frequency control device), and the air conditioner 100 runs a computer-readable storage medium corresponding to the air conditioner compressor frequency control to execute the steps in the air conditioner compressor frequency control method.

[0056] Understandable, Figure 1 The air conditioner in the scenario of the air conditioner compressor frequency control method shown, or the device contained in the air conditioner, does not constitute a limitation on the embodiments of the present invention. That is, the number or type of equipment contained in the scenario of the air conditioner compressor frequency control method, or the number or type of devices contained in each equipment, does not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be considered as equivalent substitutions or derivatives of the technical solutions claimed in the embodiments of the present invention.

[0057] In this embodiment of the invention, the air conditioner 100 is mainly used for: when the air conditioner is detected to be working, acquiring the target elastic temperature difference between the indoor temperature of the environment where the air conditioner is located and the set temperature of the air conditioner, and the target working time corresponding to the target elastic temperature difference; acquiring the first indoor temperature of the air conditioner within a first preset working time, and predicting the first predicted working time corresponding to the target elastic temperature difference based on the temperature difference change information between the first indoor temperature and the set temperature; if the first predicted working time is not equal to the target working time, controlling the compressor frequency of the air conditioner to be adjusted.

[0058] Those skilled in the art will understand that Figure 1 The application environment shown is merely one application scenario of the solution in this application and does not constitute a limitation on the application scenario of the solution in this application. Other application environments may include those that are more specific to this application. Figure 1 The number of more or fewer air conditioners shown, or the air conditioner network connection relationship, for example Figure 1 Only one air conditioner is shown in the diagram. It is understood that the scenario of the air conditioner compressor frequency control method may also include one or more other air conditioners, which are not specifically limited here. The air conditioner 100 may also include a memory for storing data, such as air conditioner working parameters.

[0059] Furthermore, in the scenario of the air conditioner compressor frequency control method of this application, the air conditioner 100 can be equipped with a display device, or the air conditioner 100 can be connected to an external display device 200 without a built-in display device. The display device 200 is used to output the result of the air conditioner compressor frequency control method execution. The air conditioner 100 can access the background database 300 (the background database can be in the local storage of the air conditioner, or it can be located in the cloud), and the background database 300 stores information related to the air conditioner compressor frequency control.

[0060] It should be noted that, Figure 1 The schematic diagram of the air conditioner compressor frequency control method shown is merely an example. The scenario of the air conditioner compressor frequency control method described in this embodiment of the invention is intended to more clearly illustrate the technical solution of this embodiment and does not constitute a limitation on the technical solution provided by this embodiment of the invention.

[0061] Based on the scenario described above regarding the frequency control method for air conditioner compressors, an embodiment of the frequency control method for air conditioner compressors is proposed.

[0062] like Figure 2 The diagram shown is a flowchart of an embodiment of the air conditioner compressor frequency control method in this application. The air conditioner compressor frequency control method includes steps S201-S203:

[0063] S201. When the air conditioner is detected to be working, the target elastic temperature difference between the indoor temperature of the environment where the air conditioner is located and the set temperature of the air conditioner, and the target working time corresponding to the target elastic temperature difference are obtained.

[0064] The work performed by the air conditioner includes different working modes such as cooling and heating. It can be understood that when an air conditioner work command is received, it means that the air conditioner is detected to be working.

[0065] The environment in which the air conditioner is located refers to the target output environment where the air conditioner performs its work, such as the environment corresponding to the output of cold air when the air conditioner is performing its cooling work. In other words, it can be understood as the indoor temperature of the environment in which the air conditioner is located, that is, the indoor ambient temperature corresponding to the output of the air conditioner, such as the temperature of the environment where the indoor unit of the air conditioner is installed.

[0066] The set temperature of the air conditioner, that is, the target temperature corresponding to the work done by the air conditioner, that is, the target temperature that the indoor environment should reach when the air conditioner does work, can be set by the user in real time, or the target temperature can be preset for different work.

[0067] The target elastic temperature difference refers to the maximum allowable temperature difference between the air conditioner's set temperature and the actual indoor temperature when the air conditioner is operating. For example, if the air conditioner is operating to control cooling and the set temperature is 25 degrees Celsius, then the required indoor temperature is 25 degrees Celsius, meaning the temperature difference between the set temperature and the actual indoor temperature is 0. The target elastic temperature refers to the allowable temperature error between the set temperature and the actual indoor temperature. For example, if the air conditioner is operating to control cooling and the set temperature is 25 degrees Celsius, and the target elastic temperature difference is 0.5 degrees Celsius, then when the indoor temperature reaches 25.5 degrees Celsius, it can be understood that the indoor temperature has reached the set temperature, and the compressor can be controlled to stop at the set temperature or operate at the lowest frequency.

[0068] The target working time corresponding to the target elastic temperature difference is the working time of the air conditioner when it works to adjust the indoor ambient temperature so that the temperature difference between the actual indoor temperature reached by the air conditioner and the set temperature of the air conditioner reaches the target elastic temperature difference. This can be understood as the target working time being a user-set time or a standard time corresponding to the temperature difference between the indoor temperature and the set temperature of the air conditioner under the corresponding operating parameters. This application does not limit the specifics. For example, if the air conditioner is controlling the cooling work and the target elastic temperature difference is 0.5 degrees Celsius, and the target working time is 3 minutes, then the air conditioner expects to achieve a temperature difference of 0.5 degrees Celsius between the actual indoor temperature reached by the air conditioner and the set temperature of the air conditioner within three minutes.

[0069] Understandably, the target runtime can be set by the user to allow the temperature difference between the indoor temperature and the set temperature to reach the target elastic temperature difference. For example, if the user needs the temperature difference between the indoor temperature and the set temperature to reach the target elastic temperature difference quickly, the target runtime can be set shorter, and vice versa. By freely adjusting the compressor frequency on the original frequency control logic, the indoor temperature reaching time can be designed for different needs, and the compressor frequency can be adjusted according to different needs, increasing the flexibility and adaptability of the compressor frequency adjustment and improving the air conditioner's performance.

[0070] It is understandable that the target running time can also be the standard time for the original frequency control logic to perform work to make the temperature difference between the indoor temperature and the set temperature reach the target elastic temperature difference. This application does not make specific limitations.

[0071] Specifically, when the air conditioner receives a work command (detects that the air conditioner is working), it acquires the target elastic temperature difference between the indoor temperature of the environment where the air conditioner is located and the set temperature of the air conditioner, as well as the target work duration corresponding to the target elastic temperature difference. It is understood that this application does not specifically limit the acquisition of the target elastic temperature difference and the target work duration corresponding to the target elastic temperature difference; for example:

[0072] One feasible implementation scheme is to search a preset database according to the working mode of the air conditioner, and obtain the target elastic temperature difference corresponding to the working mode of the air conditioner, and the target working time corresponding to the target elastic temperature difference.

[0073] A feasible implementation scheme two: The target elastic temperature difference and the target work duration corresponding to the target elastic temperature difference are collected by the data acquisition device communicating with the air conditioner. For example, the target elastic temperature difference and the target work duration corresponding to the target elastic temperature difference are collected by the air conditioner remote control communicating with the air conditioner.

[0074] S202. Obtain the first indoor temperature of the air conditioner within a first preset working time, and predict the first predicted working time corresponding to the target elastic temperature difference based on the temperature difference change information between the first indoor temperature and the set temperature.

[0075] The first preset duration is the time period from when the air conditioner starts working to when the preset duration is reached. For example, if the preset duration is 2 minutes, then the first preset duration is the first two minutes before the air conditioner starts working. It can be understood that the duration of the first preset duration can be preset according to actual needs.

[0076] The first indoor temperature, that is, the indoor temperature collected within the first preset time period, can be understood to include multiple indoor temperatures.

[0077] The temperature difference change information refers to the information on how the temperature difference between each first indoor temperature and the set temperature changes over time, such as the temperature difference change rate, temperature difference change function, temperature difference change model, etc.

[0078] The first predicted working time is the working time of the air conditioner when the ambient temperature in the room is regulated by the air conditioner based on the temperature change information during the working time of the air conditioner, so that the temperature difference between the actual indoor temperature regulated by the air conditioner and the set temperature of the air conditioner reaches the target elastic temperature difference.

[0079] It is understandable that the temperature difference change information is related to the operating frequency of the air conditioner compressor. By predicting the working time of the air conditioner through the temperature difference change information, that is, by predicting the future temperature difference change information through the temperature difference change information within the first preset working time of the air conditioner, it is possible to intuitively determine whether the current compressor frequency is over-adjusted or too low.

[0080] Specifically, after receiving the air conditioner's work command, the air conditioner obtains the corresponding preset compressor control logic based on the operating parameters corresponding to the work command, and controls the compressor frequency change according to the preset compressor control logic to achieve air conditioner work. When the air conditioner is detected to be working, multiple first indoor temperatures within a first preset time period are collected by the temperature sensor communicating with the air conditioner, and the temperature difference change information between each first indoor temperature and the set temperature of the air conditioner is calculated. Based on the temperature difference change information, the air conditioner's work duration is predicted when the temperature difference between the indoor temperature and the set temperature of the air conditioner reaches the target elastic temperature difference, and the first predicted work duration corresponding to the target elastic temperature difference is obtained.

[0081] S203. If the first predicted working time is not equal to the target working time, then the compressor frequency of the air conditioner is adjusted.

[0082] Specifically, after predicting the first predicted working time corresponding to the temperature difference between the set temperature and the target elastic temperature difference, the air conditioner matches the first predicted working time with the target working time. If the target working time is not equal to the first predicted working time, the compressor frequency of the air conditioner is adjusted.

[0083] Further, see Figure 3 , Figure 3 This is a flowchart illustrating one implementation of the air conditioning compressor frequency control method provided in this application, which predicts the first predicted work duration, including steps S301-S303:

[0084] S301. Collect the first indoor temperature within the first preset working time according to the preset temperature collection frequency.

[0085] The temperature acquisition frequency refers to the frequency at which the indoor temperature is acquired.

[0086] Specifically, the air conditioner collects multiple first indoor temperatures within a first preset working time according to its communication temperature sensor and a preset temperature collection frequency. It can be understood that multiple sensors for collecting the first indoor temperature can be set up to correspond to the indoor environment of the air conditioner. A batch of initial indoor temperatures is collected simultaneously by multiple indoor temperature sensors, and a first indoor temperature is selected from the batch of initial indoor temperatures according to a preset algorithm (mean, variance, standard deviation, etc.). That is, it can be understood that in some embodiments of this application, when multiple sensors for collecting the first indoor temperature can be set up to correspond to the indoor environment of the air conditioner, the collection frequency of the sensors for collecting the first indoor temperature is the same.

[0087] It is understood that in some other embodiments of this application, when only one sensor for collecting the first indoor temperature is set up for the indoor environment of the air conditioner, or when multiple sensors for collecting the first indoor temperature are set up for the indoor environment of the air conditioner, they may not need to collect at the same frequency, etc. The specific design can be made according to actual needs.

[0088] S302. Calculate the temperature difference between each of the first indoor temperatures and the set temperature of the air conditioner, and generate a prediction function based on each temperature difference value and the acquisition time of the indoor temperature corresponding to each temperature difference value.

[0089] The prediction function, i.e., the temperature difference change information between the first indoor temperature and the set temperature, can be understood as being calculated based on the temperature difference between the first indoor temperature and the set temperature corresponding to multiple sets of different collection times. That is, the prediction function includes the changing trend of the temperature difference between the first indoor temperature and the set temperature over time. In other words, the prediction function can be used to predict the duration of work based on the temperature difference.

[0090] Specifically, the acquisition time refers to the time information corresponding to the working duration of the air conditioner, i.e., the time when the air conditioner starts working. The acquisition time refers to the time corresponding to the working duration of the air conditioner when the first indoor temperature is acquired. In other words, the acquisition time is the working duration of the air conditioner. Further, it can be understood that the air conditioner calculates the temperature difference value based on the first indoor temperature and the set temperature corresponding to each acquisition time, obtaining multiple sets of temperature difference values ​​that correspond one-to-one with the acquisition time. Then, based on the multiple sets of temperature difference values ​​that correspond one-to-one with the acquisition time, a temperature difference change curve is generated. Subsequently, a corresponding prediction function is obtained based on the temperature difference change curve, or a preset initial prediction function is updated based on the multiple sets of temperature difference values ​​that correspond one-to-one with the acquisition time to obtain the prediction function.

[0091] Specifically, in the implementation scheme of this application, after the air conditioner calculates the temperature difference value based on the first indoor temperature and the set temperature corresponding to each collection time, and obtains multiple sets of temperature difference values ​​corresponding to each collection time, it performs curve fitting according to a preset initial prediction function to obtain the prediction function. The preset initial prediction function is described below:

[0092] ΔT=Ae (t / B) +Ct 2 +Dt+E;

[0093] Where ΔT is the temperature difference value and t is the acquisition time, that is, the temperature difference values ​​of multiple acquisition times are substituted into the initial preset function respectively, and the corresponding coefficients A, B, C, D and E are determined to obtain the fitting curve ΔT, that is, the corresponding prediction function is obtained.

[0094] It is understood that in some other embodiments of this application, the acquisition time may also be the actual time when the first indoor temperature is acquired. It is understood that, in this case, based on the actual time of the first indoor temperature and the initial time corresponding to the work done by the air conditioner, the actual working time of the air conditioner corresponding to the first indoor temperature can be obtained. Then, the prediction function is obtained based on the correspondence between the actual working time and the temperature difference. This application does not make specific limitations.

[0095] S303. Input the target elastic temperature difference into the prediction function and output the first predicted work duration corresponding to the target elastic temperature difference.

[0096] Specifically, after calculating the prediction function for predicting the working time based on the temperature difference, the air conditioner inputs the target elastic temperature difference into the prediction function and outputs the first predicted working time corresponding to the target elastic temperature difference.

[0097] Furthermore, based on any of the above implementation schemes, see [link to relevant documentation]. Figure 4 , Figure 4 This is a flowchart illustrating one embodiment of the air conditioner compressor frequency control method provided in this application, including steps S401-S402:

[0098] S401. If the first predicted working time is less than the target working time, then reduce the compressor frequency of the air conditioner.

[0099] Specifically, based on the temperature difference between the first indoor temperature and the set temperature, the air conditioner predicts the first predicted working time corresponding to the target elastic temperature difference. Then, it compares the first predicted working time with the target working time. If the first predicted working time is less than the target working time, it indicates that the current working frequency of the compressor is too high, which may cause the compressor to work and make the indoor temperature reach the set temperature in advance. This causes the compressor to continue to increase its frequency after the indoor temperature reaches the set temperature, resulting in compressor overshoot. Therefore, the compressor frequency of the air conditioner is reduced.

[0100] S402. If the first predicted working time is greater than the target working time, then increase the compressor frequency of the air conditioner.

[0101] Furthermore, after comparing the first predicted working time with the target working time, if the first predicted working time is longer than the target working time, the compressor may reach the preset working time, resulting in the indoor temperature not reaching the set temperature. This causes the compressor to stop increasing its frequency in the later stages of controlling the compressor frequency according to the preset frequency control logic, which leads to the indoor temperature not reaching the set temperature and thus reduces the compressor's temperature control efficiency. Therefore, the compressor frequency of the air conditioner is increased.

[0102] Understandably, when the compressor frequency of an air conditioner is adjusted, the increase or decrease in the compressor frequency can be set according to the actual situation, such as increasing / decreasing a preset fixed frequency value.

[0103] Specifically, in one embodiment of this application, the method for increasing or decreasing the compressor frequency is as follows:

[0104] (1) If the first predicted work duration is not equal to the target work duration, then calculate the target duration difference between the first predicted work duration and the target work duration;

[0105] (2) Find the preset mapping table corresponding to the duration difference and the adjustment frequency, and obtain the target adjustment frequency corresponding to the target duration difference;

[0106] (3) Adjust the compressor frequency of the air conditioner according to the target frequency adjustment control.

[0107] Understandably, after comparing the first predicted working time with the target working time, if the first predicted working time is less than the target working time, the compressor frequency of the air conditioner is reduced; if the first predicted working time is greater than the target working time, the compressor frequency of the air conditioner is increased. The target time difference between the first predicted working time and the target working time is calculated, and the compressor frequency is increased or decreased by a certain amount based on the target adjustment frequency corresponding to the target time difference.

[0108] It is understood that in some other embodiments of this application, after the air conditioner compares the first predicted working time with the target working time, if the first predicted working time is equal to the target working time, the air conditioner controls the compressor frequency to change according to the preset compressor frequency control logic without making any additional adjustments (i.e., neither increasing nor decreasing the existing compressor frequency).

[0109] Furthermore, based on any of the above implementation schemes, see [link to relevant documentation]. Figure 5 , Figure 5This is a schematic flowchart illustrating one implementation of the air conditioning compressor frequency control method provided in this application for obtaining the target elastic temperature difference and the target work duration, including steps S501-S503:

[0110] S501. When the air conditioner is detected to be working, collect the user's biological information corresponding to the environment in which the air conditioner is located.

[0111] The user biometric information, such as user fingerprint information and user facial image information, can be understood to be collected by a user biometric information collection sensor that communicates with the air conditioner.

[0112] S502. Based on the user's biometric information, identify the target user corresponding to the environment in which the air conditioner is located.

[0113] Specifically, when the air conditioner detects that it is working, it collects user biometric information through a user biometric information collection sensor that communicates with the air conditioner, and compares the collected user biometric information with the user data path corresponding to the air conditioner to determine the target user corresponding to the user biometric information.

[0114] S503. Based on the working parameters corresponding to the working of the air conditioner, search the user database corresponding to the target user, obtain the target elastic temperature difference between the indoor temperature and the set temperature, and the target working time corresponding to the target elastic temperature difference.

[0115] In this application embodiment, the working parameters, i.e., the working parameters corresponding to the air conditioner's operation, include the air conditioner's operating mode and the initial temperature difference between the set temperature corresponding to the air conditioner's operating mode and the initial indoor temperature collected when the air conditioner starts operating. It is understood that in some other embodiments of this application, the working parameters may only include the air conditioner's operating mode. This application does not make specific limitations.

[0116] The identification information, for example, includes a unique user ID and nickname used to identify the target user in the user repository corresponding to the air conditioner.

[0117] Among them, the user database corresponding to the target user, that is, the database corresponding to each user, can be understood as one user database, and each user database stores the air conditioning parameter configuration information of a user, including the set temperature, target elastic temperature difference, and target running time corresponding to the target elastic temperature difference under any working mode of the air conditioner (cooling mode, heating mode, etc.). It can be understood that the implementation scheme of this application only lists a part of the data in the user database.

[0118] Furthermore, in this embodiment, after receiving the air conditioner's work command, the air conditioner collects the initial indoor ambient temperature and the user's biological information of the environment where the indoor unit of the air conditioner is located. The user's biological information is compared with preset user biological information data to confirm the target user information that is the same as the preset biological information data. Then, based on the correspondence between the preset user biological information data and users, the target user corresponding to the user's biological information is determined. It can be understood that if there are multiple target users, one target user can be selected based on preset user priority, and the user database corresponding to the target user is retrieved. Based on the air conditioner's work mode and the temperature difference between the initial ambient temperature and the set temperature corresponding to the work mode, that is, based on the work parameters, the user database is searched to obtain the target elastic temperature difference between the indoor temperature and the set temperature, and the target work duration corresponding to the target elastic temperature difference.

[0119] It is understood that, based on the above implementation scheme, this application also provides an implementation scheme for obtaining the target elastic temperature difference and the target work duration, specifically including the following steps:

[0120] (1) Identify the target user corresponding to the environment where the air conditioner is located based on the user's biometric information;

[0121] (2) Based on the working parameters corresponding to the working of the air conditioner, search the user database corresponding to the target user;

[0122] (3) If the target user and the target working parameters of the air conditioner are not found, the target elastic temperature difference and the target working time are fed back as data acquisition instructions to obtain the target elastic temperature difference between the indoor temperature and the set temperature collected in response to the data acquisition instructions, and the target working time corresponding to the target elastic temperature difference.

[0123] Specifically, after receiving the air conditioner's work command, the air conditioner collects the initial indoor ambient temperature and the user's biological information about the environment where the indoor unit is located. Based on the user's biological information, it determines the target user and retrieves the user database corresponding to the target user. Based on the air conditioner's work mode and the temperature difference between the initial ambient temperature and the set temperature corresponding to the work mode (i.e., based on the work parameters), it searches the user database to obtain the target elastic temperature difference between the indoor temperature and the set temperature, and the target work duration corresponding to the target elastic temperature difference. If the target elastic temperature difference and target work duration corresponding to the work parameters are not found in the target user's user database, a data acquisition command is sent to a data acquisition device communicating with the air conditioner, such as a remote control or mobile phone. Then, the target elastic temperature difference and the target work duration corresponding to the target elastic temperature difference are collected. When the data acquisition device receives the target elastic temperature difference between the indoor temperature and the set temperature, and the target work duration corresponding to the target elastic temperature difference, in response to the data acquisition command, the data acquisition command is completed, and the target elastic temperature difference and the target work duration corresponding to the target elastic temperature difference are obtained.

[0124] Furthermore, based on any of the above implementation schemes, see [link to relevant documentation]. Figure 6 , Figure 6 A schematic flowchart of another embodiment of the air conditioner compressor frequency control method provided in this application includes steps S601-S606:

[0125] S601. When the air conditioner is detected to be working, the target elastic temperature difference between the indoor temperature of the environment where the air conditioner is located and the set temperature of the air conditioner, and the target working time corresponding to the target elastic temperature difference are obtained.

[0126] S602. Obtain the first indoor temperature of the air conditioner within a first preset working time, and predict the first predicted working time corresponding to the target elastic temperature difference based on the temperature difference change information between the first indoor temperature and the set temperature.

[0127] S603. If the first predicted working time is not equal to the target working time, then the compressor frequency of the air conditioner is adjusted.

[0128] Specifically, the specific implementation methods of steps S601-S603 are described in any of the above implementation schemes.

[0129] S604. Obtain the second indoor temperature of the environment where the air conditioner is located after the compressor frequency is adjusted.

[0130] The second indoor temperature refers to the indoor temperature collected by the air conditioner within the second preset time period. It can be understood that the second indoor temperature may include multiple or one. The second preset time period is the time period after the compressor frequency is adjusted, and the length of the time period is the second preset time period.

[0131] It is understood that the method for collecting the indoor temperature is the same as the method for collecting the first indoor temperature, and this embodiment will not elaborate on the specific details.

[0132] Specifically, after adjusting the compressor frequency of the air conditioner according to the first predicted working time and the target working time, the air conditioner collects the second indoor temperature according to the indoor temperature acquisition device communicating with the air conditioner.

[0133] S605. Based on the temperature difference change information between the second indoor temperature and the set temperature of the air conditioner, and the temperature difference change information between the first indoor temperature and the set temperature of the air conditioner, predict the second predicted work duration corresponding to the target elastic temperature difference.

[0134] If the first predicted working time is not equal to the target working time, the compressor frequency of the air conditioner is adjusted.

[0135] The second predicted working time is the working time of the air conditioner when it adjusts the ambient temperature in the room, based on the temperature difference between the second indoor temperature and the set temperature of the air conditioner when the air conditioner is working, and the temperature difference between the first indoor temperature and the set temperature of the air conditioner.

[0136] Specifically, after adjusting the compressor frequency, the air conditioner collects multiple second indoor temperatures within a second preset time period using a temperature sensor that communicates with the air conditioner. It then calculates the temperature difference change information between each second indoor temperature and the air conditioner's set temperature. Combining this with the temperature difference change information between the first indoor temperature and the air conditioner's set temperature, it predicts the working time of the air conditioner when the temperature difference between the indoor temperature and the air conditioner's set temperature reaches a target elastic temperature difference. This yields a second predicted working time corresponding to the target elastic temperature difference. For example, based on the temperature difference change information between the second indoor temperature and the air conditioner's set temperature, the temperature difference change information between the first indoor temperature and the air conditioner's set temperature is updated. That is, the prediction function obtained based on the temperature difference between the first indoor temperature and the air conditioner's set temperature is updated. Based on the updated prediction function, the working time of the air conditioner when the temperature difference between the indoor temperature and the air conditioner's set temperature reaches the target elastic temperature difference is predicted, yielding a second predicted working time.

[0137] S606. If the second predicted working time is not equal to the target working time, then the compressor frequency of the air conditioner is adjusted.

[0138] Specifically, after predicting the second predicted working time corresponding to the temperature difference between the set temperature and the target elastic temperature difference, the air conditioner matches the second predicted working time with the target working time. If the target working time is not equal to the second predicted working time, the compressor frequency of the air conditioner is further controlled for adjustment.

[0139] It is understandable that both the first preset duration and the second preset duration are less than the target running duration. That is, during the operation of the air conditioner, the compressor frequency is continuously adjusted and predicted based on the temperature change information, so that the compressor frequency adjustment is more accurate and the air conditioner's working performance is improved.

[0140] It is understood that in some other embodiments of this application, if the second predicted working time is not equal to the target working time, the compressor frequency of the air conditioner is adjusted, the third indoor temperature is acquired, and the updated prediction function is further updated based on the temperature difference between the third indoor temperature and the set temperature. The above-mentioned duration prediction action is repeated until the second predicted working time is equal to the target working time, then the acquisition of indoor ambient temperature is stopped, and the prediction function is further updated.

[0141] This application provides a method for controlling the frequency of an air conditioner compressor. When the air conditioner is detected to be working, a target elastic temperature difference between the indoor temperature of the environment where the air conditioner is located and the set temperature of the air conditioner, as well as a target working duration corresponding to the target elastic temperature difference, are obtained. A first indoor temperature within a first preset working duration is obtained, and a first predicted working duration corresponding to the target elastic temperature difference is predicted based on the temperature difference change information between the first indoor temperature and the set temperature. If the first predicted working duration is not equal to the target working duration, the compressor frequency of the air conditioner is adjusted. This solution collects the elastic temperature difference and the target working time of the elastic temperature difference, as well as the first indoor temperature. Based on the temperature difference change information between the first indoor temperature and the set temperature of the air conditioner, it predicts the first predicted working time corresponding to the elastic temperature difference. That is, it predicts the working time of the air conditioner when the temperature difference between the indoor temperature and the set temperature reaches the elastic temperature difference using the temperature difference change information between the indoor temperature and the set temperature. Then, it compares the predicted first working time with the collected target working time to evaluate whether the current working frequency of the compressor is reasonable. In this technical solution, the first target temperature difference is obtained... The elastic temperature difference is used to evaluate the compressor's operating frequency, avoiding the impact of data transmission lag on the evaluation of the compressor frequency. If the first predicted working time is not equal to the target working time, it indicates that the compressor frequency is too high or too low. The compressor frequency is then adjusted to avoid the current compressor frequency being too high or too low, causing compressor frequency overshoot or too low compressor frequency, resulting in wasted air conditioning work or insufficient temperature control (cooling or heating) capability. This avoids the inverter air conditioner's temperature control lag, and the operating frequency is repeatedly adjusted to avoid wasted air conditioning work or insufficient temperature control (cooling or heating) capability, thereby improving the air conditioner's working performance.

[0142] To better implement the air conditioner compressor frequency control method in this application embodiment, based on the air conditioner compressor frequency control method, this application embodiment also provides an air conditioner compressor frequency control device, such as...

[0148] Calculate the temperature difference between each of the first indoor temperatures and the set temperature of the air conditioner. Based on each temperature difference and the acquisition time of the indoor temperature corresponding to each temperature difference, generate a prediction function. The prediction function is used to predict the duration of work based on the temperature difference.

[0149] The target elastic temperature difference is input into the prediction function, and the first predicted work duration corresponding to the target elastic temperature difference is output.

[0151] If the first predicted working time is less than the target working time, then reduce the compressor frequency of the air conditioner;

[0152] If the first predicted working time is greater than the target working time, then the compressor frequency of the air conditioner is increased.

[0153] In one embodiment of this application, the adjustment module 703 is configured to: control the compressor frequency of the air conditioner to adjust if the first predicted work duration is not equal to the target work duration, specifically including:

[0154] If the first predicted work duration is not equal to the target work duration, then calculate the target duration difference between the first predicted work duration and the target work duration;

[0155] Find the preset mapping table corresponding to the duration difference and the adjustment frequency, and obtain the target adjustment frequency corresponding to the target duration difference;

[0156] The compressor frequency of the air conditioner is adjusted according to the target frequency adjustment control.

[0157] In one embodiment of this application, the acquisition module 701 is used to acquire the target elastic temperature difference between the indoor temperature of the environment where the air conditioner is located and the set temperature of the air conditioner, and the target work duration corresponding to the target elastic temperature difference, specifically including:

[0158] When the air conditioner is detected to be working, the user's biological information corresponding to the environment in which the air conditioner is located is collected.

[0159] Based on the user's biometric information, identify the target user corresponding to the environment in which the air conditioner is located;

[0160] Based on the working parameters corresponding to the air conditioner's work, the corresponding user database of the target user is searched to obtain the target elastic temperature difference between the indoor temperature and the set temperature, as well as the target working time corresponding to the target elastic temperature difference.

[0161] In one embodiment of this application, the acquisition module 701 is used to acquire the target elastic temperature difference between the indoor temperature of the environment where the air conditioner is located and the set temperature of the air conditioner, and the target work duration corresponding to the target elastic temperature difference, specifically including:

[0162] Based on the working parameters corresponding to the air conditioner's work, search the user database corresponding to the target user;

[0163] If the target elastic temperature difference and target working time corresponding to the target user and the air conditioner working parameters are not found, a data acquisition command is fed back to obtain the target elastic temperature difference between the indoor temperature and the set temperature collected in response to the data acquisition command, as well as the target working time corresponding to the target elastic temperature difference.

[0164] In one embodiment of this application, a duration prediction update module is further included. After the adjustment module 703 is configured to adjust the compressor frequency of the air conditioner if the first predicted working duration is not equal to the target working duration, the duration prediction update module is configured to:

[0165] Obtain the second indoor temperature of the environment where the air conditioner is located after the compressor frequency is adjusted;

[0166] Based on the temperature difference change information between the second indoor temperature and the set temperature of the air conditioner, and the temperature difference change information between the first indoor temperature and the set temperature of the air conditioner, the second predicted work duration corresponding to the target elastic temperature difference is predicted.

[0167] If the second predicted working time is not equal to the target working time, the compressor frequency of the air conditioner is adjusted.

[0168] This application provides an air conditioner compressor frequency control device, which, when detecting that the air conditioner is working, acquires a target elastic temperature difference between the indoor temperature of the environment where the air conditioner is located and the set temperature of the air conditioner, as well as a target working time corresponding to the target elastic temperature difference; acquires a first indoor temperature of the air conditioner within a first preset working time, and predicts a first predicted working time corresponding to the target elastic temperature difference based on the temperature difference change information between the first indoor temperature and the set temperature; if the first predicted working time is not equal to the target working time, the compressor frequency of the air conditioner is controlled to be adjusted. This solution collects the elastic temperature difference and the target working time of the elastic temperature difference, as well as the first indoor temperature. Based on the temperature difference change information between the first indoor temperature and the set temperature of the air conditioner, it predicts the first predicted working time corresponding to the elastic temperature difference. That is, it predicts the working time of the air conditioner when the temperature difference between the indoor temperature and the set temperature reaches the elastic temperature difference using the temperature difference change information between the indoor temperature and the set temperature. Then, it compares the predicted first working time with the collected target working time to evaluate whether the current working frequency of the compressor is reasonable. In this technical solution, the first target temperature difference is obtained... The elastic temperature difference is used to evaluate the compressor's operating frequency, avoiding the impact of data transmission lag on the evaluation of the compressor frequency. If the first predicted working time is not equal to the target working time, it indicates that the compressor frequency is too high or too low. The compressor frequency is then adjusted to avoid the current compressor frequency being too high or too low, causing compressor frequency overshoot or too low compressor frequency, resulting in wasted air conditioning work or insufficient temperature control (cooling or heating) capability. This avoids the inverter air conditioner's temperature control lag, and the operating frequency is repeatedly adjusted to avoid wasted air conditioning work or insufficient temperature control (cooling or heating) capability, thereby improving the air conditioner's working performance.
