The application provides a frequency control method and device of an air conditioner compressor, an air conditioner and a storage medium. When it is detected that the compressor reaches temperature shutdown in an air conditioner running cycle, the corresponding temperature reaching work duration and temperature reaching running frequency of the compressor reaching temperature shutdown are obtained. The target running frequency of the compressor is determined according to the temperature reaching running frequency, and the duration change information between the temperature reaching work duration and the historical temperature reaching work duration. The historical temperature reaching work duration is the historical temperature reaching work duration corresponding to the historical temperature shutdown of the compressor in the air conditioner running cycle.

In the air conditioner running process, the target running frequency corresponding to the next starting cycle of the compressor can be calculated in combination with the temperature reaching work duration corresponding to different temperature shutdown processes, so that the compressor is prevented from being frequently started and stopped or delayed to reach the shutdown requirement, and the work performance of the compressor is improved.

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 application of inverter air conditioners has become increasingly widespread. In related technologies, inverter air conditioners, during operation, primarily determine the operating frequency for reaching the set temperature based on the indoor ambient temperature and a preset frequency control logic. They then control the compressor to increase its frequency according to a preset frequency-increasing logic to achieve this operating frequency. The compressor frequency is adjusted to meet the requirement of the outdoor temperature reaching the set temperature. However, the preset frequency control logic is generally obtained through laboratory testing. Due to the diversity of air conditioner installation environments, there are still some differences between the actual installation environment and the laboratory environment. For example, the room heat load varies under different installation environments or at different times. Since the preset control logic has a fixed adjustment method, the compressor frequency adjustment based on the preset control logic will have errors under different operating environments. This can lead to problems such as frequent shutdowns after reaching the set temperature or prolonged failure to reach the set temperature during the air conditioner's operating cycle, reducing the compressor's performance. Summary of the Invention

[0003] 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 that the air conditioner controls the compressor frequency according to a preset compressor control logic, resulting in adjustment errors and reduced compressor performance. The aim is to make the compressor frequency adjustment more accurate and thereby improve the compressor performance.

[0004] In a first aspect, this application provides a method for controlling the frequency of an air conditioning compressor, comprising:

[0005] When the compressor stops at the target temperature during the air conditioning operation cycle, the temperature-reaching operation time and temperature-reaching operation frequency corresponding to the compressor stopping at the target temperature are obtained.

[0006] Based on the operating frequency at the target temperature and the duration change information between the working time at the target temperature and the historical working time at the target temperature, the target operating frequency of the compressor is determined, wherein the historical working time at the target temperature is the historical working time at the target temperature corresponding to the compressor's historical shutdown during the air conditioning operating cycle.

[0007] When the indoor temperature of the environment corresponding to the air conditioner is detected to meet the preset compressor start-up conditions, the compressor is controlled to run at the target operating frequency.

[0008] In one possible implementation of this application, the duration change information includes a target duration difference and a target duration change rate;

[0009] Determining the target operating frequency of the compressor based on the temperature-reaching operating frequency and the duration variation information between the temperature-reaching operation time and the historical temperature-reaching operation time includes:

[0010] If the number of times the compressor stops at the historical temperature during the air conditioning operation cycle is greater than the first preset number of stops, then the historical temperature-reaching working time corresponding to the compressor's historical temperature-reaching stop is obtained.

[0016] The target operating frequency of the compressor is determined based on the first target adjustment frequency and the temperature-reaching operating frequency.

[0017] In one possible implementation of this application, the duration change information includes a target duration difference;

[0018] Determining the target operating frequency of the compressor based on the temperature-reaching operating frequency and the duration variation information between the temperature-reaching operation time and the historical temperature-reaching operation time includes:

[0019] If the number of times the compressor stops at the historical temperature during the air conditioning operation cycle is less than or equal to the first preset number of stops and greater than the second preset number of stops, then the historical temperature-reaching working time corresponding to the compressor's historical temperature-reaching stops is obtained, wherein the second preset number of stops is less than the first preset number of stops.

[0020] Calculate the target duration difference between the current temperature-reaching work duration and any historical temperature-reaching work duration;

[0021] The second target adjustment frequency is determined based on the target duration difference.

[0022] The target operating frequency of the compressor is determined based on the second target adjustment frequency and the temperature-reaching operating frequency.

[0023] In one possible implementation of this application, the step of controlling the compressor to operate at a target operating frequency when the indoor temperature of the environment corresponding to the air conditioner is detected to meet the preset compressor start-up conditions includes:

[0024] When the indoor temperature of the environment corresponding to the air conditioner is detected to meet the preset compressor start-up conditions, the compressor frequency is controlled to increase, and the system pressure value of the air conditioner is collected.

[0025] Based on the pressure change information of the system pressure value, determine the target frequency correction amount;

[0026] The target operating frequency is corrected according to the target frequency correction amount;

[0027] When the compressor's operating frequency is detected to have reached the corrected target operating frequency, the compressor is controlled to operate at the corrected target operating frequency.

[0028] In one possible implementation of this application, when the compressor is detected to have reached its operating temperature and stopped during the air conditioning cycle, obtaining the operating time and frequency corresponding to the compressor reaching its operating temperature and stopping includes:

[0029] When the compressor is detected to have reached the required temperature and stopped during the air conditioning operating cycle, if the number of times the compressor has reached the required temperature and stopped during the air conditioning operating cycle is not zero, then the compressor's operating frequency and stop time at the required temperature are obtained.

[0030] Based on the compressor start-up time and the shutdown time, determine the temperature-reaching power-running time corresponding to the compressor reaching temperature and stopping.

[0031] In one possible implementation of this application, after detecting that the indoor temperature of the environment corresponding to the air conditioner meets the preset compressor start-up conditions and controlling the compressor to operate at the target operating frequency, the method further includes:

[0032] If the compressor does not reach its temperature and stop after running at the target operating frequency for a preset time, then the compressor is controlled to run at its maximum operating frequency.

[0033] Secondly, this application provides an air conditioner compressor frequency control device, the device comprising:

[0034] Detection and acquisition module: used to acquire the temperature-reaching power-running duration and temperature-reaching operation frequency corresponding to the compressor reaching temperature and stopping when the compressor is detected to have reached temperature and stopped during the air conditioning operation cycle;

[0035] Frequency determination module: used to determine the target operating frequency of the compressor based on the temperature-reaching operating frequency and the duration change information between the temperature-reaching working time and the historical temperature-reaching working time, wherein the historical temperature-reaching working time is the historical temperature-reaching working time corresponding to the compressor's historical temperature-reaching shutdown within the air conditioning operating cycle.

[0036] Control module: When the indoor temperature of the environment corresponding to the air conditioner is detected to meet the preset compressor start-up conditions, control the compressor to run at the target operating frequency.

[0037] Thirdly, this application provides an air conditioner, the air conditioner comprising:

[0038] One or more processors;

[0039] Memory; and

[0040] 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.

[0041] 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.

[0042] This application provides a method, apparatus, air conditioner, and storage medium for controlling the frequency of an air conditioner compressor. By detecting when the compressor reaches a certain temperature and stops during the air conditioner's operating cycle, the method acquires the temperature-reaching operation duration and operating frequency corresponding to the compressor's temperature-reaching shutdown. Based on the operating frequency and the duration variation information between the temperature-reaching operation duration and historical temperature-reaching operation durations, the method determines the target operating frequency of the compressor. The historical temperature-reaching operation duration refers to the historical temperature-reaching operation duration corresponding to the compressor's previous temperature-reaching shutdowns during the air conditioner's operating cycle. Then, when the indoor temperature of the environment corresponding to the air conditioner is detected to meet preset compressor start-up conditions, the method controls the compressor to operate at the target operating frequency. This solution can combine the temperature-reaching operation durations corresponding to different temperature-reaching shutdown processes during air conditioner operation. The target operating frequency for the next compressor start-up cycle is calculated, abandoning the traditional approach of determining the compressor's target operating frequency based on ambient temperature and preset control logic. This allows the compressor's target operating frequency to be dynamically adjusted based on the runtime of each temperature-reaching and shutdown cycle within the air conditioning cycle. It's understood that the compressor's runtime at temperature-reaching and shutdown is directly related to the room's heat load. Excessive heat load leads to frequent compressor starts and stops with shorter runtimes. Therefore, by dynamically adjusting the target operating frequency for the next compressor start-up based on the runtime and temperature-reaching frequency of each cycle, frequent compressor starts and stops or delays in reaching shutdown requirements are avoided, thus improving compressor performance.

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.

[0054] 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.

[0055] 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 a mobile phone or a tablet computer. The air conditioner can also be a server or a service cluster composed of multiple servers.

[0056] like Figure 1 As shown, Figure 1 This 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 of air conditioner compressor frequency control.

[0057] 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.

[0058] In this embodiment of the invention, the air conditioner 100 is mainly used for: when the compressor stops at the target temperature during the air conditioner's operating cycle, acquiring the working duration and operating frequency corresponding to the compressor stopping at the target temperature; determining the target operating frequency of the compressor based on the operating frequency and the duration change information between the working duration at the target temperature and the historical working duration at the target temperature, wherein the historical working duration at the target temperature is the historical working duration at the target temperature corresponding to the compressor stopping at the target temperature during the air conditioner's operating cycle; and controlling the compressor to operate at the target operating frequency when the indoor temperature of the environment corresponding to the air conditioner is detected to meet the preset compressor start-up conditions.

[0059] 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 storing image information acquired by shooting.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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:

[0064] S201. When the compressor stops at the temperature during the air conditioning operation cycle, the temperature-reaching working time and temperature-reaching operation frequency corresponding to the compressor stopping at the temperature are obtained.

[0065] The operating cycle of the air conditioner refers to the period between when the air conditioner starts up and operates in a specific mode until the operating mode switches, and the period between when the air conditioner starts up and operates in a specific mode until it is turned off. The operating mode, such as cooling or heating, means that within one operating cycle, the compressor will control the compressor to start and stop multiple times based on the indoor ambient temperature. For example, if the indoor temperature is higher than the air conditioner's set temperature, the compressor will start; if the indoor temperature is lower than or equal to the set temperature, the compressor will stop when the set temperature is reached. Furthermore, the set temperature can be a preset temperature corresponding to the air conditioner's operating mode, or a target set temperature that the user expects to achieve by collecting parameters from a device such as the air conditioner remote control.

[0066] Furthermore, it can be understood that the compressor reaches the set temperature and stops, that is, the air conditioner compressor stops when it detects that the indoor ambient temperature meets the preset compressor temperature stop condition. It can be understood that the preset compressor temperature stop condition is, for example, in the air conditioner cooling mode, the indoor ambient temperature is equal to the air conditioner's set temperature, or the indoor ambient temperature is less than the air conditioner's set temperature and the temperature difference between the indoor ambient temperature and the air conditioner's set temperature is equal to a preset temperature difference threshold, etc. The specific temperature stop condition can be set according to actual needs.

[0067] The term "temperature-reaching operation time" refers to the temperature-reaching shutdown cycle corresponding to when the air conditioner's compressor detects that it has reached the temperature and is shut down. This can be understood as the operating time of the compressor within the operation cycle corresponding to the temperature-reaching shutdown, i.e., the operating time of the compressor from startup to shutdown.

[0068] It is understandable that the time required to reach the operating temperature can be determined by collecting the time when the compressor starts up and the time when the compressor stops, and by using the start-up time and the stop time as the basis for determining the time required to reach the operating temperature.

[0069] The operating frequency at the temperature reached is the compressor operating frequency when it receives the temperature-reaching shutdown command. For example, if the compressor receives the temperature-reaching shutdown command while operating at 100 Hz / second, then the operating frequency at the temperature reached is 100 Hz / second.

[0070] Specifically, in the implementation scheme of this application, the air conditioner compressor frequency control method is applied to an air conditioner compressor frequency control device. The air conditioner compressor frequency control device is installed inside the air conditioner. That is, during the air conditioner's operating cycle, when the indoor temperature is detected to meet the preset compressor temperature-reaching shutdown conditions (i.e., the compressor temperature-reaching shutdown is detected), the current operating frequency of the compressor is obtained and set as the temperature-reaching operating frequency. The shutdown time is determined based on the compressor start time and the shutdown time, and the temperature-reaching power-running duration corresponding to the compressor temperature-reaching shutdown is determined, and the compressor temperature-reaching shutdown is controlled.

[0071] S202. Determine the target operating frequency of the compressor based on the temperature-reaching operating frequency and the duration change information between the temperature-reaching working time and the historical temperature-reaching working time.

[0072] Wherein, the historical temperature-reaching operation time is the historical temperature-reaching operation time corresponding to the compressor's historical temperature-reaching shutdown within the air conditioner's operating cycle; that is, it includes the temperature-reaching operation time from the first temperature-reaching shutdown to the previous temperature-reaching shutdown within the air conditioner's operating cycle. It can be understood that the number of historical temperature-reaching operation times is not limited, for example:

[0073] In one embodiment of this application, the air conditioner detects that the compressor has reached a certain temperature and stopped during the air conditioner's operating cycle. Specifically, it acquires the operating time corresponding to the compressor reaching the temperature and stopped, and after determining the target frequency by comparing it with previously collected historical operating times, sets this as the historical operating time. This means that when the compressor is detected to have reached a certain temperature and stopped again during the air conditioner's operating cycle, it is used together with the previously collected historical operating times as the historical operating times. Thus, as the air conditioner's operating cycle becomes normal and the number of times it stops at a certain temperature increases, the number of historical operating times also increases, achieving dynamic updates to the historical operating time database and increasing data accuracy.

[0074] In another embodiment of this application, if the air conditioner has too long an operating cycle, resulting in too many historical temperature-reaching working times and too much data processing, an upper limit can be set for the number of historical temperature-reaching working times. When the number of historical temperature-reaching working times reaches the upper limit, the value includes the number of historical temperature-reaching working times corresponding to the time closest to the current temperature-reaching shutdown time of the compressor.

[0075] The duration change information includes, for example, at least one of the following: duration change curve, duration difference, duration change rate, etc. Specifically, the target operating frequency is used to control the operating frequency corresponding to the next start of the compressor within the air conditioner operating cycle. The specific implementation method for determining the target operating frequency of the compressor based on the temperature-reaching operating frequency and the duration change information between the temperature-reaching working time and the historical temperature-reaching working time is not specifically limited in this application. For example:

[0076] One feasible implementation scheme: After obtaining the temperature-reaching operation time and operating frequency corresponding to the compressor reaching the temperature and stopping, the air conditioner calculates the temperature difference between the temperature-reaching operation time and the historical temperature-reaching operation time. For example, it calculates the difference between the temperature-reaching operation time and any historical temperature-reaching operation time, or, according to the time sequence corresponding to the historical temperature-reaching operation time, it calculates the difference between adjacent historical temperature-reaching operation times on the time axis, and the difference between the temperature-reaching operation time and the temperature-reaching operation time corresponding to the last temperature-reaching shutdown. Then, it calculates the mean of all differences to obtain the mean difference. Then, it looks up a preset mapping table based on the difference / mean difference and the temperature-reaching operating frequency to determine the target operating frequency.

[0077] Implementation scheme two: After obtaining the temperature-reaching operation time and temperature-reaching operating frequency corresponding to the compressor reaching the temperature and stopping, the air conditioner calculates the temperature difference between the temperature-reaching operation time and any historical temperature-reaching operation time, and calculates the temperature difference change rate between the temperature-reaching operation time and the historical temperature-reaching operation time. Based on the temperature difference change rate and the temperature difference value, the adjustment frequency for adjusting the temperature-reaching operating frequency is determined. Based on the adjustment frequency and the temperature-reaching operating frequency, the target operating frequency of the compressor is determined.

[0078] Implementation scheme 3: After obtaining the temperature-reaching operation time and temperature-reaching operating frequency corresponding to the compressor reaching temperature and stopping, the air conditioner calculates the time change rate of the temperature-reaching operation time and the corresponding time sequence of historical temperature-reaching operation times, determines the adjustment frequency for adjusting the temperature-reaching operating frequency based on the time change rate, and determines the target operating frequency of the compressor based on the adjustment frequency and the temperature-reaching operating frequency.

[0079] S203. When the indoor temperature of the environment corresponding to the air conditioner is detected to meet the preset compressor start-up conditions, the compressor is controlled to run at the target operating frequency.

[0080] The indoor temperature corresponding to the air conditioner's output is the ambient temperature of the room where the air conditioner is installed, such as the ambient temperature of the room where the air conditioner is installed.

[0081] The preset compressor start-up conditions, i.e. the conditions for controlling the compressor to start, can be designed according to actual needs. For example, when the working mode corresponding to the air conditioner's operating cycle is the cooling mode, the preset compressor start-up conditions can be that the indoor temperature is greater than the set temperature corresponding to the air conditioner's cooling mode; or it can be that the indoor temperature is greater than the set temperature corresponding to the air conditioner's cooling mode, and the temperature difference between the indoor temperature and the set temperature corresponding to the air conditioner's cooling mode is greater than a preset temperature difference threshold.

[0082] Specifically, when the air conditioner detects that the compressor has reached the set temperature and stopped during the air conditioner's operating cycle, it acquires the working duration and operating frequency corresponding to the compressor reaching the set temperature and stopped. Based on the operating frequency and the duration change information between the working duration and the historical working duration, it determines the target operating frequency of the compressor and detects the indoor temperature. If the indoor temperature meets the preset compressor start-up conditions, it controls the compressor to start and increase its frequency until the compressor's operating frequency reaches the target operating frequency. Then, it controls the compressor to operate at the target operating frequency.

[0083] Furthermore, based on the above implementation scheme, this application also provides one implementation scheme for determining the target operating frequency in the air conditioning compressor frequency control method. In this implementation scheme, the duration change information includes the target duration difference and the target duration change rate.

[0084] See Figure 3 , Figure 3 This is a flowchart illustrating one implementation of the target operating frequency determination method for an air conditioning compressor provided in this application, including steps S301-S304:

[0085] S301. If the number of times the compressor stops at the historical temperature during the air conditioning operation cycle is greater than the first preset number of stops, then obtain the historical temperature-reaching working time corresponding to the historical temperature-reaching stop of the compressor.

[0086] The historical number of times the compressor reaches the temperature and stops is the number of times the compressor has reached the temperature and stopped during the air conditioning operating cycle, excluding the currently detected compressor temperature and stop. For example, if the compressor reaches the temperature and stops during the air conditioning operating cycle for the third time during the cycle, then the historical number of times the compressor reaches the temperature and stops is 2.

[0087] It is understandable that during the air conditioner's operating cycle, when the compressor is detected to have reached the required temperature and stopped, the number of times the compressor stops at the required temperature is accumulated. When the air conditioner's operating cycle ends, the accumulated data is cleared. In other words, it is understandable that the historical number of times the air conditioner's compressor stops at the required temperature can be directly obtained.

[0088] The first preset number of shutdowns is used to determine whether the target duration change rate can be calculated based on the temperature-reaching working time and the historical temperature-reaching working time. It can be understood that if the historical temperature-reaching shutdown count is less than two, then the number of historical temperature-reaching working times is also less than 2. In this case, the target duration change rate cannot be calculated based on the historical temperature-reaching working time and the temperature-reaching working time. That is, it can be understood that the first preset number of shutdowns is greater than or equal to 2.

[0089] Specifically, when the air conditioner detects that the compressor has reached the temperature and stopped during the air conditioner's operating cycle, it obtains the historical number of times the compressor has reached the temperature and stops, and determines whether the historical number of times the compressor has reached the temperature and stops is greater than the first preset number of times it has stopped. If the historical number of times the compressor has reached the temperature and stops during the air conditioner's operating cycle is greater than the first preset number of times it has stopped, it obtains the historical temperature-reaching working time corresponding to the historical temperature-reaching stop of the compressor.

[0090] S302. Calculate the target duration difference between the current temperature-reaching work duration and any historical temperature-reaching work duration.

[0091] Wherein, the working time of any historical temperature reaching can be the working time of the previous temperature reaching shutdown corresponding to the currently detected temperature reaching shutdown, or it can be the working time of the historical temperature reaching shutdown corresponding to the two-year-older temperature reaching shutdown corresponding to the currently detected temperature reaching shutdown. In the embodiment of this application, the working time of any historical temperature reaching is the working time of the previous temperature reaching shutdown corresponding to the currently detected temperature reaching shutdown, that is, the working time of the historical temperature reaching with the shortest time interval to the current time.

[0092] Specifically, after obtaining the historical temperature-reaching shutdown time corresponding to the compressor's historical temperature-reaching shutdown, the air conditioner calculates the time difference between the temperature-reaching shutdown time and the historical temperature-reaching shutdown time with the shortest current time interval, and obtains the target time difference.

[0093] S303. Calculate the target duration change rate based on the current working time at the target temperature and the historical working time at the target temperature.

[0094] The target duration change rate refers to the adjacent relationship between the current temperature-reaching operation duration and the historical temperature-reaching operation duration on the time axis. After calculating the duration difference, the change rate of the duration difference with time can be understood as follows: the adjacent relationship on the time axis means that one historical temperature-reaching operation duration corresponds to one compressor temperature-reaching shutdown within the air conditioner's operating cycle; each historical temperature-reaching operation duration corresponds to a different time period distributed on the time axis; and the current temperature-reaching operation duration and the historical temperature-reaching operation duration are arranged sequentially on the time axis. The adjacent relationship means that there is an adjacent relationship between the two temperature-reaching operation durations with the shortest time interval between the current temperature-reaching operation duration and the historical temperature-reaching operation duration on the time axis.

[0095] Specifically, after calculating the target duration difference between the current temperature-reaching working time and any historical temperature-reaching working time, the air conditioner will calculate the duration difference between adjacent temperature-reaching working times on the time axis based on the arrangement relationship between the current temperature-reaching working time and the historical temperature-reaching working time (including the duration difference between adjacent historical temperature-reaching working times and the difference between the current temperature-reaching working time and adjacent historical temperature-reaching working times); then, the target duration change rate will be calculated based on each duration difference.

[0096] S304. Determine the target operating frequency of the compressor based on the target duration difference, the target duration change rate, and the temperature-reaching operating frequency.

[0097] Specifically, after calculating the target duration difference and the target duration change rate, the air conditioner determines the target operating frequency of the compressor based on the target duration difference, the target duration change rate, and the temperature-reaching operating frequency. This process includes the following steps:

[0098] (1) Find the preset mapping table corresponding to the duration difference, duration change rate and adjustment frequency, and obtain the first target adjustment frequency corresponding to the target duration difference and the target duration change rate;

[0099] (2) Determine the target operating frequency of the compressor based on the first target adjustment frequency and the temperature-reaching operating frequency.

[0100] The preset mapping table includes multiple mapping relationship groups, and each mapping relationship group includes a mapping relationship between a duration difference, a duration change rate, and an adjustment frequency.

[0101] The first target adjustment frequency is the compressor operating frequency to be adjusted.

[0102] It is understood that after calculating the target duration difference and the target duration change rate, the air conditioner looks up a preset mapping table corresponding to the duration difference, duration change rate, and adjustment frequency to obtain the first target adjustment frequency corresponding to the target duration difference and the target duration change rate. Based on the first target adjustment frequency and the temperature-reaching operating frequency, the air conditioner determines the target operating frequency of the compressor. It is understood that the target operating frequency of the compressor is determined based on the first target adjustment frequency and the temperature-reaching operating frequency. For example, the first target adjustment frequency and the temperature-reaching operating frequency are added together to determine the target operating frequency of the compressor. It is understood that the first target adjustment frequency can be a negative or positive number, and this application does not make specific limitations on it.

[0103] Furthermore, based on the above implementation scheme, this application also provides another implementation scheme for determining the target operating frequency in the air conditioning compressor frequency control method. In this implementation scheme, the duration change information includes the target duration difference.

[0104] See Figure 4 , Figure 4 A flowchart illustrating another implementation of the target operating frequency determination method for the air conditioner compressor frequency control provided in this application, including steps S401-S404:

[0105] S401. If the number of times the compressor has stopped at the historical temperature during the air conditioning operation cycle is less than or equal to the first preset number of stops and greater than the second preset number of stops, then obtain the historical temperature-reaching working time corresponding to the historical temperature-reaching stop of the compressor.

[0106] Wherein, the second preset number of shutdowns is less than the first preset number of shutdowns; it can be understood that the second preset number of shutdowns is used to determine whether the target duration difference can be calculated based on the temperature-reaching working time and the historical temperature-reaching working time. It can be understood that if the historical temperature-reaching shutdown count is less than 1, then the number of historical temperature-reaching working times is also less than 1, that is, there is no historical temperature-reaching working time, and the current compressor temperature-reaching is the first temperature-reaching shutdown in the air conditioning operation cycle. At this time, the target duration difference cannot be calculated based on the historical temperature-reaching working time and the temperature-reaching working time. That is, it can be understood that the first preset number of shutdowns is greater than or equal to 1.

[0107] Specifically, when the air conditioner detects that the compressor has reached the required temperature and stopped during the air conditioner's operating cycle, it obtains the historical number of times the compressor has stopped at the required temperature and determines whether the historical number of times the compressor has stopped at the required temperature is greater than or equal to the second preset number of stops and less than or equal to the first preset number of stops. If the historical number of times the compressor has stopped at the required temperature during the air conditioner's operating cycle is less than or equal to the first preset number of stops and greater than the second preset number of stops, then the historical working time corresponding to the historical temperature stop of the compressor is obtained.

[0108] S402. Calculate the target duration difference between the current temperature-reaching work duration and any historical temperature-reaching work duration.

[0109] Wherein, the working time of any historical temperature reaching can be the working time of the previous temperature reaching shutdown corresponding to the currently detected temperature reaching shutdown, or it can be the working time of the historical temperature reaching shutdown corresponding to the two-year-older temperature reaching shutdown corresponding to the currently detected temperature reaching shutdown. In the embodiment of this application, the working time of any historical temperature reaching is the working time of the previous temperature reaching shutdown corresponding to the currently detected temperature reaching shutdown, that is, the working time of the historical temperature reaching with the shortest time interval to the current time.

[0110] Specifically, after obtaining the historical temperature-reaching shutdown time corresponding to the compressor's historical temperature-reaching shutdown, the air conditioner calculates the time difference between the temperature-reaching shutdown time and the historical temperature-reaching shutdown time with the shortest current time interval, and obtains the target time difference.

[0111] S403. Determine the second target adjustment frequency based on the target duration difference.

[0112] The second target adjustment frequency is the compressor operating frequency to be adjusted.

[0113] Specifically, after calculating the target duration difference, the air conditioner looks up a preset mapping table corresponding to the duration difference and the adjustment frequency, obtains the second target adjustment frequency corresponding to the target duration difference and the target duration change rate, and determines the target operating frequency of the compressor based on the second target adjustment frequency and the temperature-reaching operating frequency.

[0114] S404. Determine the target operating frequency of the compressor based on the second target adjustment frequency and the temperature-reaching operating frequency.

[0115] It is understood that the target operating frequency of the compressor is determined based on the second target adjustment frequency and the temperature-reaching operating frequency. For example, the second target adjustment frequency and the temperature-reaching operating frequency are added together to determine the target operating frequency of the compressor. It is understood that the second target adjustment frequency can be a negative or positive number, and this application does not make specific limitations on it.

[0116] It is understood that in some other embodiments of this application, after the air conditioner detects that the compressor has reached the temperature and stopped during the air conditioner's operating cycle, it obtains the historical number of times the compressor has reached the temperature and stops, and determines whether the historical number of times the compressor has reached the temperature and stops is greater than the first preset number of times it has stopped. If the historical number of times the compressor has reached the temperature and stops during the air conditioner's operating cycle is not greater than the first preset number of times it has stopped, the operating frequency at the temperature can also be set as the target operating frequency.

[0117] It is understood that in some other embodiments of this application, after the air conditioner detects that the compressor has reached the temperature and stopped during the air conditioner's operating cycle, it obtains the historical number of times the compressor has reached the temperature and stops, and determines whether the historical number of times the compressor has reached the temperature and stops is less than or equal to a first preset number of stops and greater than a second preset number of stops. If the historical number of times the compressor has reached the temperature and stops during the air conditioner's operating cycle is less than the second preset number of stops, then the operating frequency for reaching the temperature is set as the target operating frequency.

[0118] Furthermore, based on the above implementation plan, see [link to relevant documentation]. Figure 5 , Figure 5 This is a flowchart illustrating one implementation scheme of the air conditioner compressor frequency control method provided in this application, including steps S501-S504:

[0119] S501. When the indoor temperature of the environment corresponding to the air conditioner is detected to meet the preset compressor start-up conditions, the compressor frequency is controlled to increase, and the system pressure value of the air conditioner is collected.

[0120] The system pressure value of the air conditioner can be the pressure value on the low-pressure side of the compressor, or the pressure value on the high-pressure side, or the refrigerant pressure value in the evaporator coil of the air conditioner. In the embodiment of this application, the system pressure value is the low-pressure value on the low-pressure side of the compressor.

[0121] Specifically, after determining the target operating frequency, the air conditioner detects the indoor temperature of the environment corresponding to the air conditioner. When the indoor temperature of the environment corresponding to the air conditioner meets the preset compressor start-up conditions, the air conditioner controls the compressor to increase its frequency and collects the system pressure value of the air conditioner. It can be understood that the system pressure value of the air conditioner can be collected only during the frequency increase process, or it can be collected during the entire operation of the compressor. That is, the action of collecting the system pressure value of the air conditioner can continue from the frequency increase stage until the compressor reaches the target operating frequency and stops when the temperature is reached.

[0122] S502. Determine the target frequency correction amount based on the pressure change information of the system pressure value.

[0123] The pressure change information may include, for example, pressure change rate, pressure change curve, pressure difference, and pressure difference change rate.

[0124] The target frequency correction amount can be either the correction frequency or the frequency correction coefficient.

[0125] Specifically, in the technical solution of this application, the pressure change information refers to the pressure difference change rate on the low-pressure side of the compressor. After the air conditioner controls the compressor to increase its frequency, it collects the low-pressure values ​​corresponding to different times on the low-pressure side of the compressor and calculates the pressure difference change information corresponding to the time to obtain the target pressure difference change rate. The target pressure difference change rate is the pressure change information. Then, the target frequency correction amount is determined based on the target pressure difference change rate. It can be understood that the target frequency correction amount can be obtained by looking up a preset mapping table corresponding to the pressure difference change rate and the correction frequency.

[0126] S503. Correct the target operating frequency according to the target frequency correction amount.

[0127] Specifically, after obtaining the target frequency correction amount, the air conditioner corrects the target operating frequency based on the target frequency correction amount. For example, if the target frequency correction amount is a correction frequency, the target operating frequency and the correction frequency are added together. It can be understood that the correction frequency can be a positive or negative number. If the target frequency correction amount is a frequency correction coefficient, the target operating frequency and the correction frequency can be multiplied together.

[0128] S504. When the compressor's operating frequency is detected to have reached the corrected target operating frequency, the compressor is controlled to operate at the corrected target operating frequency.

[0129] Specifically, after the air conditioner controls the compressor to increase its frequency, it acquires the system pressure value of the air conditioner and determines the target frequency correction amount based on the pressure change information of the system pressure value. The target operating frequency is then corrected based on the target frequency correction amount. If the current compressor frequency increases to reach the target operating frequency before correction, the compressor is controlled to either increase or decrease its frequency so that the compressor operates at the corrected target operating frequency. If the current compressor frequency increases but does not reach the target operating frequency before correction, the compressor is controlled to increase its frequency until it reaches the corrected target operating frequency so that the compressor operates at the corrected target operating frequency.

[0130] Furthermore, based on any of the above implementation schemes, this application also provides an implementation scheme for collecting the working time and operating frequency at the temperature reached, including the following steps:

[0131] (1) When the compressor stops at the temperature during the air conditioning operation cycle, if the number of times the compressor stops at the temperature during the air conditioning operation cycle is not zero, the compressor’s operating frequency and shutdown time at the temperature are obtained.

[0132] (2) Determine the temperature-reaching work duration corresponding to the compressor reaching temperature and stopping based on the compressor start-up time and the shutdown time.

[0133] It is understood that if the number of times the compressor has stopped at the historical temperature during the air conditioning operation cycle is zero, then there is no historical temperature stop during the air conditioning operation cycle, and the compressor's temperature operation frequency and stop time are not determined at this time; the step of determining the temperature-reaching work duration corresponding to the compressor's temperature stop based on the compressor's start time and stop time is executed.

[0134] Furthermore, in one embodiment of this application, when the air conditioner detects that the compressor has reached a certain temperature and stopped during the air conditioner's operating cycle, it acquires the temperature-reaching operation time and operating frequency corresponding to the temperature-reaching shutdown. Based on the temperature-reaching operating frequency and the time variation information between the temperature-reaching operation time and historical temperature-reaching operation times, it determines the target operating frequency of the compressor. When it is detected that the indoor temperature of the environment corresponding to the air conditioner meets the preset compressor start-up conditions, it controls the compressor to operate at the target operating frequency. When it is detected that the indoor temperature of the environment corresponding to the air conditioner meets the preset compressor start-up conditions, it controls the compressor to operate at the target operating frequency and monitors the operating time of the compressor at the target operating frequency. If the compressor has not been detected to stop at the target operating frequency after operating at the target operating frequency for a preset time, it controls the compressor to operate at the maximum operating frequency.

[0135] This application provides an air conditioning compressor frequency control method. When the compressor reaches a certain temperature and stops during the air conditioning operating cycle, the method acquires the temperature-reaching operation duration and operating frequency corresponding to this temperature-reaching shutdown. Based on the operating frequency and the duration variation information between the temperature-reaching operation duration and historical temperature-reaching operation durations, the method determines the target operating frequency of the compressor. The historical temperature-reaching operation duration refers to the historical temperature-reaching operation duration corresponding to the compressor's previous temperature-reaching shutdowns during the air conditioning operating cycle. Then, when the indoor temperature of the environment corresponding to the air conditioning is detected to meet preset compressor start-up conditions, the method controls the compressor to operate at the target operating frequency. This method can combine the temperature-reaching operation duration corresponding to different temperature-reaching shutdown processes to control the compressor frequency during air conditioning operation. The target operating frequency for the next start-up cycle of the compressor is calculated, abandoning the traditional approach of determining the compressor's target operating frequency based on ambient temperature and preset control logic. This allows the compressor's target operating frequency to be dynamically adjusted based on the runtime of each temperature-reaching and shutdown cycle within the air conditioning cycle. It's understood that the length of the compressor's runtime corresponding to temperature-reaching and shutdown is directly related to the room's heat load. Excessive heat load leads to frequent compressor starts and stops, and shorter compressor runtimes. Therefore, by dynamically adjusting the target operating frequency for the next compressor start-up based on the runtime of each temperature-reaching and shutdown cycle and the temperature-reaching frequency, frequent compressor starts and stops or delays in reaching shutdown requirements are avoided, thus improving the compressor's performance.

[0136] 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...

[0149] If the number of times the compressor stops at the historical temperature during the air conditioning operation cycle is less than or equal to the first preset number of stops and greater than the second preset number of stops, then the historical temperature-reaching working time corresponding to the compressor's historical temperature-reaching stops is obtained, wherein the second preset number of stops is less than the first preset number of stops.

[0150] Calculate the target duration difference between the current temperature-reaching work duration and any historical temperature-reaching work duration;

[0151] The second target adjustment frequency is determined based on the target duration difference.

[0152] The target operating frequency of the compressor is determined based on the second target adjustment frequency and the temperature-reaching operating frequency.

[0153] In one embodiment of this application, the control module 603 is configured to control the compressor to operate at a target operating frequency when the indoor temperature of the environment corresponding to the air conditioner is detected to meet a preset compressor start-up condition, specifically including:

[0154] When the indoor temperature of the environment corresponding to the air conditioner is detected to meet the preset compressor start-up conditions, the compressor frequency is controlled to increase, and the system pressure value of the air conditioner is collected.

[0155] Based on the pressure change information of the system pressure value, determine the target frequency correction amount;

[0156] The target operating frequency is corrected according to the target frequency correction amount;

[0157] When the compressor's operating frequency is detected to have reached the corrected target operating frequency, the compressor is controlled to operate at the corrected target operating frequency.

[0158] In one embodiment of this application, the detection and acquisition module 601 is used to acquire the temperature-reaching work duration and temperature-reaching operation frequency corresponding to the compressor reaching temperature and stopping during the air conditioning operation cycle, specifically including:

[0159] When the compressor is detected to have reached the required temperature and stopped during the air conditioning operating cycle, if the number of times the compressor has reached the required temperature and stopped during the air conditioning operating cycle is not zero, then the compressor's operating frequency and stop time at the required temperature are obtained.

[0160] Based on the compressor start-up time and the shutdown time, determine the temperature-reaching power-running time corresponding to the compressor reaching temperature and stopping.

[0161] In one embodiment of this application, the control module 603: after detecting that the indoor temperature of the environment corresponding to the air conditioner meets the preset compressor start-up conditions and controlling the compressor to operate at the target operating frequency, further includes:

[0162] If the compressor does not reach its temperature and stop after running at the target operating frequency for a preset time, then the compressor is controlled to run at its maximum operating frequency.

[0163] The implementation scheme of this application provides an air conditioning compressor frequency control device.

The historical temperature-reaching operation time is the historical temperature-reaching operation time corresponding to the compressor's historical temperature-reaching shutdown during the air conditioning operating cycle. Then, when the indoor temperature of the environment corresponding to the air conditioning is detected to meet preset compressor start-up conditions, the compressor is controlled to operate at the target operating frequency. This scheme can combine the temperature-reaching operation time corresponding to different temperature-reaching shutdown processes to control the compressor frequency during air conditioning operation. The target operating frequency for the next start-up cycle of the compressor is calculated, abandoning the traditional approach of determining the compressor's target operating frequency based on ambient temperature and preset control logic. This allows the compressor's target operating frequency to be dynamically adjusted based on the runtime of each temperature-reaching and shutdown cycle within the air conditioning cycle. It's understood that the length of the compressor's runtime corresponding to temperature-reaching and shutdown is directly related to the room's heat load. Excessive heat load leads to frequent compressor starts and stops, and shorter compressor runtimes. Therefore, by dynamically adjusting the target operating frequency for the next compressor start-up based on the runtime of each temperature-reaching and shutdown cycle and the temperature-reaching frequency, frequent compressor starts and stops or delays in reaching shutdown requirements are avoided, thus improving the compressor's performance.
