[0063] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0064] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0065] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0066] The main solution of this application embodiment is: to determine the expected power of the air conditioner based on the expected power consumption and the expected operating time; to determine the target frequency of the compressor based on the temperature difference between the initial indoor temperature and the set temperature and the expected power; to determine the control parameters based on the target frequency and the expected operating time, and to control the operation of the air conditioner based on the control parameters.

[0067] In this embodiment, for ease of description, the following description uses an air conditioner as the subject of execution.

[0068] Because existing air conditioners are usually labeled with energy efficiency ratings, users cannot intuitively measure the total power consumption of the air conditioner over a certain period of time from the energy efficiency rating. Therefore, it is impossible to control energy consumption based on the energy efficiency rating, and it cannot meet users' needs for energy saving.

[0069] This application provides a solution that controls the operation of an air conditioner by controlling the expected power consumption and expected operating time, so that the power consumption of the air conditioner does not exceed the expected power consumption, thereby saving the power consumption of the air conditioner and improving the user experience.

[0070] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or air conditioner capable of performing the above functions. The following description uses an air conditioner as an example to illustrate this embodiment and the subsequent embodiments.

[0071] Based on this, the embodiments of this application provide a control method for an air conditioner, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the control method for the air conditioner of this application.

[0072] In this embodiment, the control method of the air conditioner includes steps S10 to S30:

[0073] Step S10: Determine the expected power of the air conditioner based on the expected power consumption and expected operating time.

[0074] It should be noted that users can customize the product according to their own heating and cooling needs and energy-saving habits. The system will then perform fuzzy distribution control based on the user's set power consumption to meet the user's energy-saving needs.

[0075] After the air conditioner is turned on, users can customize power consumption and operating time settings according to their own habits via remote control or terminal device application. After the desired power consumption is set, the compressor's operating frequency and corresponding operating time are calculated and adjusted based on actual operating conditions. The air conditioner operates according to the fuzzy calculation of operating frequency and operating time, and its operation is continuously monitored. When the power consumption reaches the desired power consumption or the operating time reaches the desired operating time, the air conditioner is controlled to operate in fan mode until the user restarts or exits the power setting mode.

[0076] It should be noted that the expected power consumption is the total power consumption that the user expects to consume during this air conditioner operation. Optionally, the expected power consumption is set by the user. By setting the expected power consumption, electricity bills are prevented from increasing, thus improving the user experience. Optionally, the expected power consumption can be determined based on the user's historical power consumption, such as the average or median of historical power consumption. By determining the expected power consumption in advance and reminding the user of their power consumption, the user can control their electricity usage and improve the user experience.

[0077] In one optional embodiment, the historical operating time period corresponding to the current time period is determined; the expected power consumption is determined based on the historical power consumption of the historical operating time period. Optionally, multiple historical operating time periods are determined based on the current time period, and the expected power consumption is determined based on the average historical power consumption of the multiple historical operating time periods. For example, if the current time period is summer with higher temperatures, the corresponding historical operating time period is also summer; if the current time period is winter with lower temperatures, the corresponding historical operating time period is also winter.

[0078] Optionally, the historical operating time period corresponding to the current time period can be determined; based on the historical power consumption of the historical operating time period, the recommended power consumption can be determined, and the user can input the expected power consumption based on the recommended power consumption, thereby improving the user's flexibility in setting the power consumption.

[0079] It should be noted that the expected runtime is the total duration the user expects the air conditioner to run during this operation. Optionally, the expected runtime is set by the user. Optionally, the expected runtime can be generated based on the user's historical runtimes, for example, the expected runtime can be the average, median, or other values ​​of historical runtimes.

[0080] In an optional embodiment, the historical running time period corresponding to the current time period is determined; the expected running time is determined based on the historical running time within the historical running time period. Optionally, multiple historical running time periods are determined based on the current time period, and the expected running time is determined based on the average of the historical running time of the multiple historical running time periods. For example, if the current time period is summer with higher temperatures, the corresponding historical running time period is also summer; if the current time period is winter with lower temperatures, the corresponding historical running time period is also winter.

[0081] Optionally, the historical operating time period corresponding to the current time period is determined; based on the historical operating time within the historical operating time period, a recommended operating time is determined; the user inputs the desired operating time based on the recommended operating time, thereby controlling the range of the user's operating time setting to avoid unreasonable operating time settings, such as the indoor ambient temperature failing to reach the set temperature when the operating time is too long and the power consumption is fixed.

[0082] In an optional embodiment, an energy-saving settings interface is displayed, which includes a power consumption setting area and a runtime setting area. Based on a trigger operation in the power consumption setting area, the user's desired power consumption is obtained; based on a trigger operation in the runtime setting area, the user's desired runtime is obtained, thus improving the user's flexibility in setting power consumption and runtime. Optionally, the trigger operation can be a selection operation or an input operation, or it can be a click operation, a double-click operation, or other similar types.

[0083] Optionally, the expected power of the air conditioner is determined based on the ratio of expected power consumption to expected operating time. For example, the expected power is calculated using the following formula:

[0084]

[0085] Where P represents the expected power of the air conditioner, Q represents the expected power consumption, and t represents the expected operating time.

[0086] Optionally, the power consumption over time is determined based on the expected power consumption; the expected power of the air conditioner is determined based on the ratio of the power consumption over time to the operating time. For example, the expected power consumption over time is shown in the following formula:

[0087]

[0088] f(t) = t 2 -C;

[0089] Where Q represents the expected power consumption, t represents the expected running time, t≥0, C>0, and C is a constant.

[0090] The expected power is calculated using the following formula:

[0091]

[0092] Where P represents the expected power of the air conditioner, Q represents the expected power consumption, and t represents the expected operating time.

[0093] Step S20: Determine the target frequency of the compressor based on the temperature difference between the initial indoor temperature and the set temperature and the desired power.

[0094] It should be noted that the initial indoor temperature is the indoor ambient temperature when the air conditioner is turned on. The initial indoor temperature can be the ambient temperature in the target space, such as the ambient temperature in the bedroom.

[0095] Optionally, the set temperature can be the target temperature that the air conditioner needs to achieve when it is operated, which is input by the user, or the target temperature that the air conditioner needs to achieve when it is operated, which is determined according to the operating mode input by the user. The operating mode includes heating mode, cooling mode, defrosting mode, and dehumidification mode, etc.

[0096] Optionally, the product of the air conditioner's rated power and the temperature difference is determined; the target frequency of the compressor is determined based on the ratio between the desired power and the product. An example is shown in the following formula:

[0097]

[0098] Where Fr represents the compressor's operating frequency, P represents the air conditioner's desired power, Pc represents the compressor's rated power at its rated frequency (which can be found in the compressor's datasheet), and ΔT represents the temperature difference between the initial indoor temperature and the set temperature, as shown in the following formula:

[0099] ΔT=T1-T s ;

[0100] Where T1 represents the initial indoor temperature, T s This indicates the set temperature.

[0101] In one feasible embodiment, step S20 includes: determining a preset correction coefficient, the product of the air conditioner's rated power and the temperature difference; and determining the target frequency of the compressor based on the ratio between the desired power and the product value. An example is shown in the following formula:

[0102]

[0103] Where Fr represents the compressor's operating frequency, P represents the air conditioner's desired power, Pc represents the compressor's rated power at its rated frequency (which can be found in the compressor's datasheet), and K is a correction factor. ΔT represents the temperature difference between the initial indoor temperature and the set temperature, as shown in the following formula:

[0104] ΔT=T1-T s ;

[0105] Where T1 represents the initial indoor temperature, T s This indicates the set temperature.

[0106] Optionally, the temperature difference between the initial indoor temperature and the set temperature is positively correlated with the correction coefficient; that is, the smaller the temperature difference, the smaller the correction coefficient, and the larger the temperature difference, the larger the correction coefficient. For example, the correction coefficient ranges from 0.8 to 1.2.

[0107] It should be noted that the target frequency of the compressor can be a fixed frequency value or a frequency curve that changes over time.

[0108] Step S30: Determine control parameters based on the target frequency and the desired operating time, and control the air conditioner to operate based on the control parameters.

[0109] It should be noted that the control parameters are used to control the operation of the air conditioner. The operating frequency control parameters of the compressor are determined according to the target frequency, and the operating time control parameters of the air conditioner are determined according to the expected operating time. Based on the operating frequency control parameters and the operating time control parameters, the operation of the air conditioner's compressor is controlled.

[0110] Optionally, when the total power consumption of the air conditioner is greater than or equal to the expected power consumption, a prompt message is output, or the air conditioner is controlled to stop operating, or the air conditioner is controlled to execute the air supply mode, or the air conditioner is controlled to execute the normal operation mode, such as the cooling mode or the heating mode.

[0111] Optionally, when the actual operating time of the air conditioner is greater than or equal to the expected operating time, a prompt message is output, or the air conditioner is controlled to stop operating, or the air conditioner is controlled to execute the air supply mode, or the air conditioner is controlled to execute the normal operating mode, such as the cooling mode or the heating mode.

[0112] Optionally, after step S30, the method further includes: when the change in outdoor ambient temperature is greater than a preset temperature threshold, or the change in temperature difference is greater than a preset difference threshold, updating the target frequency based on the current outdoor ambient temperature and the desired power, and returning to step S20. This avoids frequent updates to energy-saving control while updating control parameters based on changes in ambient temperature, thus improving the accuracy of energy-saving control.

[0113] In this embodiment, the expected power of the air conditioner is determined based on the expected power consumption and the expected operating time; the target frequency of the compressor is determined based on the temperature difference between the initial indoor temperature and the set temperature and the expected power; control parameters are determined based on the target frequency and the expected operating time, and the air conditioner is controlled to operate based on these control parameters. By controlling the air conditioner's operation based on the expected power consumption and the expected operating time, the air conditioner's power consumption does not exceed the expected power consumption, saving power and improving the user experience.

[0114] Based on the first embodiment of this application, in the second embodiment of this application, the same or similar content as the above embodiment can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 After step S30, the following steps are also included:

[0115] Step S40: Determine the actual power of the air conditioner based on its actual operating parameters;

[0116] Step S50: Determine the current power consumption based on the actual power and the current cumulative running time;

[0117] Step S60: When the current power consumption is greater than or equal to the expected power consumption, output a prompt message or display the actual power consumption in real time.

[0118] Because air conditioners have certain parameter limitations, or the control parameters may have low precision, the expected operating parameters may not match the actual operating parameters. Therefore, the actual power of the air conditioner is determined based on its actual operating parameters, and the current power consumption is determined based on the actual power and the current cumulative operating time.

[0119] When the current power consumption is less than the expected power consumption, the remaining power consumption is determined based on the expected power consumption and the current power consumption, the remaining operating time is determined based on the expected operating time and the current cumulative operating time, the expected power of the air conditioner is determined based on the remaining power consumption and the remaining operating time, and the process returns to steps S20 to S30.

[0120] When the current power consumption is greater than or equal to the expected power consumption, it indicates that the current expected power consumption has been exhausted, and a prompt message is output, or the actual power consumption is displayed in real time to remind the user of the current power consumption.

[0121] Optionally, when the current cumulative runtime is greater than or equal to the expected runtime, a prompt message may be output, or the actual power consumption may be displayed in real time.

[0122] In the technical solution of this embodiment, the operation of the air conditioner is controlled by setting the expected power consumption and the expected running time. The operation of the air conditioner is monitored according to the actual power consumption, which ensures the accuracy of the power consumption control of the air conditioner, saves the power consumption of the air conditioner, and improves the user experience.

[0123] In the third embodiment of this application, the same or similar content as in the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 3 The method includes:

[0124] Step S70: Determine the temperature difference between the set temperature and the current initial indoor temperature;

[0125] Step S80: Determine the estimated power consumption per unit time based on the temperature difference, and display the estimated power consumption per unit time corresponding to the set temperature;

[0126] Step S90: Determine the expected power consumption based on the estimated power consumption per unit time.

[0127] It should be noted that after obtaining the set temperature Ts, the system will simultaneously display the estimated power consumption per unit time through fuzzy calculation based on the set temperature, for the user's reference and energy-saving settings. Optionally, the set temperature can be the target temperature that the air conditioner needs to achieve, as input by the user, or the target temperature that the air conditioner needs to achieve, determined according to the operating mode input by the user. The operating mode includes heating mode, cooling mode, defrosting mode, and dehumidification mode, etc.

[0128] Energy consumption is essentially the work done to counteract heat transfer between indoor and outdoor environments. The principle of fuzzy logic involves using heat transfer formulas based on a set temperature and the current outdoor temperature to calculate the amount of heat transferred from the outside to the inside per unit time, thus providing an approximate power consumption per unit time, i.e., the estimated power consumption per unit time.

[0129] Optionally, when the set temperature or the outdoor ambient temperature changes, the power consumption will also be updated synchronously through fuzzy calculation, providing real-time updates on the power consumption per unit time at the corresponding set temperature, allowing users to set it according to their own needs.

[0130] In the technical solution of this embodiment, by inputting the set temperature, the expected power consumption per unit time is obtained, allowing the user to intuitively observe the power consumption of the air conditioner, which facilitates the user to set the desired power consumption for energy-saving control of the air conditioner.

[0131] Based on the third embodiment of this application, in the fourth embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 4 After step S90, the method further includes:

[0132] Step S10: Determine the expected power of the air conditioner based on the expected power consumption and expected operating time.

[0133] Step S20: Determine the target frequency of the compressor based on the temperature difference between the initial indoor temperature and the set temperature and the desired power.

[0134] Step S30: Determine control parameters based on the target frequency and the desired operating time, and control the air conditioner to operate based on the control parameters.

[0135] It should be noted that users can customize the product according to their own heating and cooling needs and energy-saving habits. The system will then perform fuzzy distribution control based on the user's set power consumption to meet the user's energy-saving needs.

[0136] After the air conditioner is turned on, users can customize power consumption and operating time settings according to their own habits via remote control or terminal device application. After the desired power consumption is set, the compressor's operating frequency and corresponding operating time are calculated and adjusted based on actual operating conditions. The air conditioner operates according to the fuzzy calculation of operating frequency and operating time, and its operation is continuously monitored. When the power consumption reaches the desired power consumption or the operating time reaches the desired operating time, the air conditioner is controlled to operate in fan mode until the user restarts or exits the power setting mode.

[0137] It should be noted that the expected power consumption is the total power consumption that the user expects to consume during this air conditioner operation. Optionally, the expected power consumption is set by the user. By setting the expected power consumption, electricity bills are prevented from increasing, thus improving the user experience. Optionally, the expected power consumption can be determined based on the user's historical power consumption, such as the average or median of historical power consumption. By determining the expected power consumption in advance and reminding the user of their power consumption, the user can control their electricity usage and improve the user experience.

[0138] In one optional embodiment, the historical operating time period corresponding to the current time period is determined; the expected power consumption is determined based on the historical power consumption of the historical operating time period. Optionally, multiple historical operating time periods are determined based on the current time period, and the expected power consumption is determined based on the average historical power consumption of the multiple historical operating time periods. For example, if the current time period is summer with higher temperatures, the corresponding historical operating time period is also summer; if the current time period is winter with lower temperatures, the corresponding historical operating time period is also winter.

[0139] Optionally, the historical operating time period corresponding to the current time period can be determined; based on the historical power consumption of the historical operating time period, the recommended power consumption can be determined, and the user can input the expected power consumption based on the recommended power consumption, thereby improving the user's flexibility in setting the power consumption.

Optionally, the expected runtime can be generated based on the user's historical runtimes, for example, the expected runtime can be the average, median, or other values ​​of historical runtimes.

[0141] In an optional embodiment, the historical running time period corresponding to the current time period is determined; the expected running time is determined based on the historical running time within the historical running time period. Optionally, multiple historical running time periods are determined based on the current time period, and the expected running time is determined based on the average of the historical running time of the multiple historical running time periods. For example, if the current time period is summer with higher temperatures, the corresponding historical running time period is also summer; if the current time period is winter with lower temperatures, the corresponding historical running time period is also winter.

[0142] Optionally, the historical operating time period corresponding to the current time period is determined; based on the historical operating time within the historical operating time period, a recommended operating time is determined; the user inputs the desired operating time based on the recommended operating time, thereby controlling the range of the user's operating time setting to avoid unreasonable operating time settings, such as the indoor ambient temperature failing to reach the set temperature when the operating time is too long and the power consumption is fixed.

[0144] Optionally, the expected power of the air conditioner is determined based on the ratio of expected power consumption to expected operating time. For example, the expected power is calculated using the following formula:

[0145]

[0147] Optionally, the power consumption over time is determined based on the expected power consumption; the expected power of the air conditioner is determined based on the ratio of the power consumption over time to the operating time. For example, the expected power consumption over time is shown in the following formula:

[0148]

[0155] Optionally, the set temperature can be the target temperature that the air conditioner needs to achieve when it is operated, which is input by the user, or the target temperature that the air conditioner needs to achieve when it is operated, which is determined according to the operating mode input by the user. The operating mode includes heating mode, cooling mode, defrosting mode, and dehumidification mode, etc.

[0156] Optionally, the product of the air conditioner's rated power and the temperature difference is determined; the target frequency of the compressor is determined based on the ratio between the desired power and the product. An example is shown in the following formula:

[0157]

[0158] Where Fr represents the compressor's operating frequency, P represents the air conditioner's desired power, Pc represents the compressor's rated power at its rated frequency (which can be found in the compressor's datasheet), and ΔT represents the temperature difference between the initial indoor temperature and the set temperature, as shown in the following formula:

[0159] ΔT=T1-T s ;

[0160] Where T1 represents the initial indoor temperature, T s This indicates the set temperature.

[0161] In one feasible embodiment, step S20 includes: determining a preset correction coefficient, the product of the air conditioner's rated power and the temperature difference; and determining the target frequency of the compressor based on the ratio between the desired power and the product value. An example is shown in the following formula:

[0162]

[0163] Where Fr represents the compressor's operating frequency, P represents the air conditioner's desired power, Pc represents the compressor's rated power at its rated frequency (which can be found in the compressor's datasheet), and K is a correction factor. ΔT represents the temperature difference between the initial indoor temperature and the set temperature, as shown in the following formula:

[0164] ΔT=T1-T s ;

[0165] Where T1 represents the initial indoor temperature, T s This indicates the set temperature.

[0166] Optionally, the temperature difference between the initial indoor temperature and the set temperature is positively correlated with the correction coefficient; that is, the smaller the temperature difference, the smaller the correction coefficient, and the larger the temperature difference, the larger the correction coefficient. For example, the correction coefficient ranges from 0.8 to 1.2.

[0167] It should be noted that the target frequency of the compressor can be a fixed frequency value or a frequency curve that changes over time.

[0168] It should be noted that the control parameters are used to control the operation of the air conditioner. The operating frequency control parameters of the compressor are determined according to the target frequency, and the operating time control parameters of the air conditioner are determined according to the expected operating time. Based on the operating frequency control parameters and the operating time control parameters, the operation of the air conditioner's compressor is controlled.

[0169] Optionally, when the total power consumption of the air conditioner is greater than or equal to the expected power consumption, a prompt message is output, or the air conditioner is controlled to stop operating, or the air conditioner is controlled to execute the air supply mode, or the air conditioner is controlled to execute the normal operation mode, such as the cooling mode or the heating mode.

[0170] Optionally, when the actual operating time of the air conditioner is greater than or equal to the expected operating time, a prompt message is output, or the air conditioner is controlled to stop operating, or the air conditioner is controlled to execute the air supply mode, or the air conditioner is controlled to execute the normal operating mode, such as the cooling mode or the heating mode.

[0171] Optionally, after step S30, the method further includes: when the change in outdoor ambient temperature is greater than a preset temperature threshold, or the change in temperature difference is greater than a preset difference threshold, updating the target frequency based on the current outdoor ambient temperature and the desired power, and returning to step S20. This avoids frequent updates to energy-saving control while updating control parameters based on changes in ambient temperature, thus improving the accuracy of energy-saving control.

[0172] In this embodiment, the expected power of the air conditioner is determined based on the expected power consumption and the expected operating time; the target frequency of the compressor is determined based on the temperature difference between the initial indoor temperature and the set temperature and the expected power; control parameters are determined based on the target frequency and the expected operating time, and the air conditioner is controlled to operate based on these control parameters. By controlling the air conditioner's operation based on the expected power consumption and the expected operating time, the air conditioner's power consumption does not exceed the expected power consumption, saving power and improving the user experience.

[0173] Based on the third or fourth embodiment of this application, in the fifth embodiment of this application, the content that is the same as or similar to the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 5 After step S30, the following steps are also included:

[0174] Step S40: Determine the actual power of the air conditioner based on its actual operating parameters;

[0175] Step S50: Determine the current power consumption based on the actual power and the current cumulative running time;

[0176] Step S60: When the current power consumption is greater than or equal to the expected power consumption, output a prompt message or display the actual power consumption in real time.

[0177] Because air conditioners have certain parameter limitations, or the control parameters may have low precision, the expected operating parameters may not match the actual operating parameters. Therefore, the actual power of the air conditioner is determined based on its actual operating parameters, and the current power consumption is determined based on the actual power and the current cumulative operating time.

[0178] When the current power consumption is less than the expected power consumption, the remaining power consumption is determined based on the expected power consumption and the current power consumption, the remaining operating time is determined based on the expected operating time and the current cumulative operating time, the expected power of the air conditioner is determined based on the remaining power consumption and the remaining operating time, and the process returns to steps S20 to S30.

[0179] When the current power consumption is greater than or equal to the expected power consumption, it indicates that the current expected power consumption has been exhausted, and a prompt message is output, or the actual power consumption is displayed in real time to remind the user of the current power consumption.

[0180] Optionally, when the current cumulative runtime is greater than or equal to the expected runtime, a prompt message may be output, or the actual power consumption may be displayed in real time.

[0181] In the technical solution of this embodiment, the operation of the air conditioner is controlled by setting the expected power consumption and the expected running time. The operation of the air conditioner is monitored according to the actual power consumption, which ensures the accuracy of the power consumption control of the air conditioner, saves the power consumption of the air conditioner, and improves the user experience.

[0182] For example, to help understand the control system of the air conditioner control method obtained by combining the above embodiments, please refer to... Figure 6 , Figure 6 A schematic diagram of the control system for an air conditioner is provided, specifically:

[0183] After the system is powered on, users can customize the power consumption and time settings according to their own habits via remote control or terminal application software. After the power consumption Q is set, the system sends feedback to the calculation module. The calculation module, through three other smaller calculation modules, calculates the product's operating frequency and the operating time for each frequency, and transmits this information to the feedback module. After receiving the information, the feedback module corrects it based on the actual operating conditions and then transmits it to the receiving module. The product then operates according to the fuzzy calculation frequency and operating time. The monitoring module starts continuous monitoring after receiving the signal from the receiving module. When the system energy consumption reaches the user-set power consumption Q or operating time, it returns the information to the receiving module. The receiving module then operates in air supply mode until the user restarts the device or exits the power consumption setting mode.

[0184] The calculation module includes: a power calculation module, a temperature difference calculation module, and a time calculation module.

[0185] The power calculation module is used to determine the power consumption over time based on the expected power consumption; and to determine the expected power of the air conditioner based on the ratio of the power consumption over time to the operating time. For example, the expected power consumption over time is shown in the following formula:

[0186]

[0187] f(t) = t 2 -C;

[0188] Where Q represents the expected power consumption, t represents the expected running time, t≥0, C>0, and C is a constant.

[0189] The expected power is calculated using the following formula:

[0190]

[0191] Where P represents the expected power of the air conditioner, Q represents the expected power consumption, and t represents the expected operating time.

[0192] The temperature difference calculation module is used to determine the product of a preset correction coefficient, the rated power of the air conditioner, and the temperature difference; and to determine the target frequency of the compressor based on the ratio between the desired power and the product value. An example is shown in the following formula:

[0193]

[0194] Where Fr represents the compressor's operating frequency, P represents the air conditioner's desired power, Pc represents the compressor's rated power at its rated frequency (which can be found in the compressor's datasheet), and K is a correction factor. ΔT represents the temperature difference between the initial indoor temperature and the set temperature, as shown in the following formula:

[0195] ΔT=T1-T s ;

[0196] Where T1 represents the initial indoor temperature, T s This indicates the set temperature.

[0197] Optionally, the temperature difference between the initial indoor temperature and the set temperature is positively correlated with the correction coefficient; that is, the smaller the temperature difference, the smaller the correction coefficient, and the larger the temperature difference, the larger the correction coefficient. For example, the correction coefficient ranges from 0.8 to 1.2.

[0198] The time calculation module is used to obtain the operating time t for each frequency based on the power calculated above and the operating frequency.

[0199] The feedback module is used to send the results of the calculation module back to the main control board.

[0200] The receiving module is used to issue instructions, and the system operates according to the data from the computing module.

[0201] The monitoring module continuously monitors the receiving module and provides feedback to the receiving module after the command action is completed.

[0202] When a user sets a specific temperature Ts, the system uses fuzzy calculations to simultaneously display the estimated power consumption per unit time for the user's reference. Energy consumption is essentially the work done to counteract heat transfer between the indoor and outdoor environments. Based on the user-set Ts and the current outdoor temperature T4, the system uses heat transfer formulas to calculate the amount of heat transferred from the outside to the inside per unit time, thus providing an approximate power consumption per unit time. When the user's Ts or T4 changes, the power consumption is updated synchronously through fuzzy calculations, providing real-time updates on the power consumption per unit time for the corresponding set temperature, allowing the user to set the appropriate level according to their needs.

[0203] In the technical solution of this embodiment, the operation of the air conditioner is controlled by the expected power consumption and the expected running time, so that the power consumption of the air conditioner does not exceed the expected power consumption, thereby saving the power consumption of the air conditioner and improving the user experience.
