Abstract
Description
Technical Field
[0001] This application relates to the field of power regulation technology, and in particular to an air conditioner power correction method, apparatus and system and air conditioner. Background Technology
[0002] Existing air conditioning systems generally employ fixed power control, which cannot dynamically adjust to changes in ambient temperature, user habits, or grid load. This rigid operating mode is particularly problematic under heavy load conditions: when temperatures change abruptly or user loads are high, the system continuously operates at peak power, causing significant power fluctuations, impacting the grid, affecting power supply stability and quality, and potentially leading to localized overload risks. Simultaneously, the frequent start-stop cycles of the air conditioner to maintain the set temperature result in significant indoor temperature fluctuations, reducing user comfort. In terms of energy efficiency, fixed power control struggles to adapt to changes in actual cooling demand, often resulting in "over-cooling" or delayed response, causing the system to deviate from its efficient operating range for extended periods and increasing ineffective energy consumption.
[0003] Therefore, achieving a dynamic balance among grid load, user comfort, and system energy efficiency has become a critical issue that urgently needs to be addressed in the optimization of air conditioning systems. Promoting the intelligent and adaptive control capabilities of air conditioning systems is an important direction for enhancing electricity demand flexibility, ensuring grid security, and promoting energy conservation and emission reduction. Summary of the Invention
[0004] In order to overcome the shortcomings of the prior art, this application provides an air conditioning power correction method, device and system and air conditioner to solve the problems of poor grid stability, low energy efficiency and poor user experience caused by the fixed power control mode of the existing air conditioning system, its inability to adapt to dynamically changing environmental and grid conditions, and the lack of fine power correction capability.

[0008] As an optional implementation of this application, it also includes: When the current operating phase is the power-on phase, the target parameter satisfies the preset condition if any of the following conditions exist: The temperature difference is greater than or equal to a threshold, and the temperature change rate is greater than or equal to a preset temperature change rate, wherein the temperature change rate is the time required for the indoor ambient temperature to change to a preset temperature value, and the temperature difference is the absolute value of the difference between the indoor ambient temperature and the set temperature. The temperature and humidity comprehensive index is greater than or equal to the corresponding preset value. The temperature and humidity comprehensive index is a parameter determined based on the indoor ambient temperature and indoor ambient humidity.

[0009] As an optional implementation of this application, it also includes: When the current operation phase is a stable operation phase, the target parameter satisfies the preset condition if any of the following conditions exist: The outdoor ambient temperature is greater than or equal to the preset outdoor ambient temperature, and the current current is greater than or equal to the product of the first preset coefficient and the effective current. The preset outdoor ambient temperature varies depending on the air conditioning operating mode.

[0010] As an optional implementation of this application, it also includes: After the air conditioner is turned on, the temperature difference value is obtained.

[0015] As an optional implementation of this application, it also includes: Record the number of adjustments.

Alternatively, when performing power correction, if the duration of a continuous difference between the indoor ambient temperature and the set temperature that is greater than the preset difference exceeds the sixth preset duration, the limit ratio will be increased or power correction will be exited.
[0017] As an optional implementation of this application, it also includes: After adjusting the current to the limiting current, the corrected operating effect parameters are obtained. The operating effect parameters include any one of the following: current change, temperature difference, and room temperature recovery rate.

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be described in detail below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0026] Reference Figure 1 This application provides an air conditioner power correction method, including: S11: Obtain the target parameter, which represents the current operating load; S12: When the target parameter meets the preset conditions, power correction is performed, and the power correction is used to reduce the current.
[0027] The air conditioning power correction method provided in this application includes: acquiring a target parameter, which represents the current operating load; and performing power correction when the target parameter meets preset conditions, wherein the power correction is used to reduce the current. This application achieves dynamic and precise adjustment of air conditioning power by acquiring the target parameter representing the operating load in real time and performing power correction to reduce current when preset conditions are met. This not only effectively adapts to dynamic changes in the environment and power grid, improving power grid stability and system energy efficiency, but also avoids overload or frequent start-stop, improving user experience.
[0028] Example 1: This application provides a method for correcting air conditioner power during the start-up and operation phase, such as... Figure 2 As shown, it includes: S21: Determine the current operating stage as the power-on operating stage; In one embodiment, the current running stage is determined based on the runtime since power-on: The system is considered to be in the power-on phase if it is detected as powered on (e.g., after receiving a power-on command) for a specified duration (e.g., one hour), and then in the stable operation phase after the specified power-on duration.
[0029] In another embodiment, the current operating phase is determined based on the temperature difference between the indoor ambient temperature and the set temperature. The system is considered to be in the start-up phase when the temperature difference between the indoor ambient temperature and the set temperature is greater than or equal to the specified temperature difference. It is considered to be in the stable operation phase when the temperature difference is less than the specified temperature difference. This is because the difference between the indoor temperature and the set temperature is larger during the start-up phase and smaller during the stable operation phase.
[0030] Alternatively, the system is defined as being in operation when the temperature difference between the indoor ambient temperature and the set temperature changes by a specified value within a preset period, and as being in stable operation when the temperature difference within the preset period is less than the specified value. This is because during the start-up phase, the temperature difference between the indoor ambient temperature and the set temperature is relatively large, and the rate of change in the indoor temperature is relatively fast, resulting in a large change within the preset period.
[0031] S22: The target parameters are determined to be any one of the following sets of parameters, wherein the target parameters are used to represent the current operating load: The temperature change rate and temperature difference are used. The temperature change rate is the time required for the indoor ambient temperature to change to a preset temperature value. The temperature difference is the absolute value of the difference between the indoor ambient temperature and the set temperature. The purpose of using this parameter is to correct the power during the start-up and operation phase by using the temperature difference and temperature change rate to ensure that the room temperature meets the user's needs. This reduces the user's temperature adjustment needs and the corresponding load on the air conditioner during operation.
[0032] Indoor ambient temperature and humidity are used as target parameters because their combined effect more accurately reflects the actual heat load felt by the human body, rather than just the ambient temperature load. Comprehensive temperature and humidity indices calculated based on indoor ambient temperature and humidity (such as THI (Temperature-Humidity Index, also known as the discomfort index, a single indicator comprehensively evaluating the impact of temperature and humidity on human thermal perception) or WBGT (Wet-Bulb Globe Temperature, a more comprehensive indicator that considers the influence of radiant heat (through the black bulb temperature) in addition to temperature and humidity) can more scientifically assess perceived comfort. This allows power adjustments to more accurately match human comfort needs while meeting basic cooling requirements, avoiding overcooling or insufficient dehumidification that may result from solely adjusting temperature, directly improving the user experience. A more comprehensive load assessment can prevent blindly maintaining high-power cooling in high-temperature and high-humidity environments due to high perceived temperature, or unnecessary excessive cooling when humidity is suitable. This helps to reduce operating current more intelligently while ensuring comfort, thereby saving energy and reducing the load on the power grid and the equipment itself, and improving the economy and reliability of system operation.
[0033] Indoor ambient temperature, indoor ambient humidity, and indoor air quality. This set of parameters incorporates indoor air quality, such as PM2.5 index or air pollution index, in addition to indoor ambient temperature and humidity. This is because some high air conditioning loads may not be due to temperature and humidity, but rather to poor indoor air quality, thus resulting in higher loads.
[0034] S23: Obtain the target parameters; The specific target parameters can be obtained from the actual sensor, and this application does not limit them here.
[0035] S24: When the target parameter meets the preset conditions, power correction is performed, and the power correction is used to reduce the current.
[0036] When the current operating phase is the power-on phase, the target parameter satisfies the preset condition if any of the following conditions exist: The temperature difference is greater than or equal to a threshold, and the temperature change rate is greater than or equal to a preset temperature change rate, wherein the temperature change rate is the time required for the indoor ambient temperature to change to a preset temperature value, and the temperature difference is the absolute value of the difference between the indoor ambient temperature and the set temperature. The temperature and humidity comprehensive index is greater than or equal to the corresponding preset value. The temperature and humidity comprehensive index is a parameter determined based on the indoor ambient temperature and indoor ambient humidity. The temperature and humidity comprehensive index can be THI or WBGT. The corresponding parameters are the corresponding technologies. This application has not improved its calculation method and will not provide it here.
[0037] The combined temperature and humidity index is less than the corresponding preset value, but the air quality index is greater than the preset value.
[0038] It should be noted that the target parameter in this application embodiment may be only one type or all types, and the target parameter is determined to meet the preset conditions after any one of them is triggered.
[0039] As a preferred implementation of this application embodiment, the power correction includes: Adjust the current to the limit current, where the limit current = limit ratio * target current, the limit ratio is a positive number less than 1, and the target current is the current current or the effective current.
[0040] Preferably, such as Figure 5 As shown: S51: Record the number of adjustments. After each adjustment, the number of adjustments is incremented by 1, and the number of adjustments is cleared to zero when exiting power correction. S52: When power correction is required, if the number of adjustments is less than or equal to the preset number, the current is adjusted to the limit current. In one embodiment, the limit ratio remains constant during each adjustment, or the limit ratio decreases as the number of adjustments increases. This is because a large number of adjustments indicates that the current load is still very high after adjustment, thus requiring further reduction of the current.
[0041] S53: If the number of adjustments exceeds the preset number, then the current remains unchanged.
[0042] Of course, in practice, the limiting current = target current - fixed threshold.
[0043] As a preferred implementation of the embodiments of this application, it further includes: When performing power correction, the current is compensated every five time intervals, and the current value for each compensation is 1 / N, where N is the preset number of compensations.
[0044] Among them, power correction is exited after a preset number of continuous compensations; Alternatively, when performing power correction, if the duration of a continuous difference between the indoor ambient temperature and the set temperature that is greater than the preset difference exceeds the sixth preset duration, the limit ratio will be increased or power correction will be exited.
[0045] In one embodiment, such as Figure 6 As shown, it also includes: S61: After adjusting the current to the limit current, obtain the corrected operating effect parameters, which include any one of the following: current change, temperature difference and room temperature recovery rate; S62: Adjust the limit ratio based on the operating effect parameters.
[0046] For example, if the temperature difference increases after the current is adjusted to the limiting current, the value of the limiting ratio is increased; if the temperature difference decreases and the rate of decrease is greater than a threshold after the current is adjusted to the limiting current, the value of the limiting ratio is decreased.
[0047] In another embodiment, such as Figure 7 As shown, it also includes: S71: Obtain outdoor ambient temperature; S72: Determine a limiting ratio based on the outdoor ambient temperature, wherein the smaller the absolute value of the difference between the outdoor ambient temperature and the preset outdoor ambient temperature, the larger the limiting ratio.
[0048] Understandably, a curve or formula can be set to determine a limiting ratio for the absolute value of the difference between each outdoor ambient temperature and a preset outdoor ambient temperature. Alternatively, the outdoor ambient temperature can be pre-divided into multiple ranges, each corresponding to a limiting ratio. For example: a low-temperature range (< 18℃), a normal-temperature range (18~32℃), and a high-temperature range (> 32℃), with the power correction magnitude dynamically adjusted based on changes in the current ambient temperature and load current. For instance, in a high-temperature environment, if a continuous increase in load current is detected, a stricter power limiting strategy is adopted (e.g., Ilimited current = Ieffective (effective current) × 70%); in a normal-temperature environment, a milder limiting strategy is adopted (e.g., Ilimited current = Ieffective × 85%); and in a low-temperature environment, a moderate limiting strategy is adopted (e.g., Ilimited current = Ieffective × 80%).
[0049] In one embodiment, the effective current is a current value determined based on user settings or big data.
[0050] In another embodiment, such as Figure 4 As shown, the effective current is obtained using the following method: S41: After the air conditioner is started, a temperature difference value is obtained, wherein the temperature difference value is the absolute value of the difference between the indoor ambient temperature and the set temperature; S42: When the temperature difference is greater than or equal to the first preset temperature difference, the recording of valid current is enabled. When the recording of valid current is enabled: the current is sampled once every first preset time interval; when the difference between the current sampled this time and the current sampled last time is greater than or equal to the preset current difference, the current sampled this time is taken as the valid current.
[0051] In one embodiment, the first preset duration is a fixed duration.
[0052] In another embodiment, the first preset duration is determined based on the temperature difference and the temperature change rate, wherein the temperature change rate is the duration required for the indoor ambient temperature to change to a preset temperature value, and when the temperature change rate is constant, the larger the temperature difference, the smaller the first preset duration.
[0053] The correspondence between the temperature difference and the rate of temperature change and the first preset duration can be preset in advance, such as by using formulas, curves or tables.
[0054] As a preferred implementation of the embodiments of this application, it further includes: The effective current is cleared when any of the following conditions are met: The device was not turned on again within the second preset time period; The effective current has not been updated for the third consecutive preset time period during operation; The temperature difference is detected to be less than or equal to a second preset temperature difference, wherein the second preset temperature difference is less than a first preset temperature difference.
[0055] The air conditioner power correction method provided in this application includes: when the current operating stage is the start-up stage, determining and acquiring corresponding target parameters, the target parameters representing the current operating load; and when the target parameters meet preset conditions, performing power correction to reduce the current. This application achieves dynamic and precise adjustment of air conditioner power by acquiring target parameters representing the operating load in real time and performing power correction to reduce current when preset conditions are met. This not only effectively adapts to dynamic changes in the environment and power grid, improving power grid stability and system energy efficiency, but also avoids overload or frequent start-stop cycles, improving user experience.
[0056] It should be noted that any process or method description in the flowchart or otherwise described herein can be understood as representing a module, segment, or portion of code comprising one or more executable instructions for implementing a particular logical function or process, and the scope of the preferred embodiments of this application includes additional implementations in which functions may be performed not in the order shown or discussed, including substantially simultaneously or in reverse order according to the functions involved, as should be understood by those skilled in the art to which the embodiments of this application pertain.
[0057] Furthermore, in the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0058] Example 2: This application provides a method for correcting air conditioner power during the start-up and operation phase, such as... Figure 3 As shown, it includes: S31: Determine the current operating phase as a stable operating phase; In one embodiment, the current running stage is determined based on the runtime since power-on: The system is considered to be in the power-on phase if it is detected as powered on (e.g., after receiving a power-on command) for a specified duration (e.g., one hour), and then in the stable operation phase after the specified power-on duration.
[0059] In another embodiment, the current operating phase is determined based on the temperature difference between the indoor ambient temperature and the set temperature. The system is considered to be in the start-up phase when the temperature difference between the indoor ambient temperature and the set temperature is greater than or equal to the specified temperature difference. It is considered to be in the stable operation phase when the temperature difference is less than the specified temperature difference. This is because the difference between the indoor temperature and the set temperature is larger during the start-up phase and smaller during the stable operation phase.
[0060] Alternatively, the system is defined as being in operation when the temperature difference between the indoor ambient temperature and the set temperature changes by a specified value within a preset period, and as being in stable operation when the temperature difference within the preset period is less than the specified value. This is because during the start-up phase, the temperature difference between the indoor ambient temperature and the set temperature is relatively large, and the rate of change in the indoor temperature is relatively fast, resulting in a large change within the preset period.
[0061] S32: The target parameter is determined to be the outdoor ambient temperature.
[0062] S33: Obtain target parameters; The specific target parameters can be obtained from the actual sensor, and this application does not limit them here.
[0063] S34: When the target parameter meets the preset conditions, power correction is performed, and the power correction is used to reduce the current.
[0064] As a preferred implementation of this application embodiment: when the current running stage is a stable running stage, the target parameter satisfies the preset condition if any of the following conditions exist: The outdoor ambient temperature is greater than or equal to the preset outdoor ambient temperature, and the current current is greater than or equal to the product of the first preset coefficient and the effective current. The preset outdoor ambient temperature varies depending on the air conditioning operating mode. The outdoor ambient temperature is lower than the preset outdoor ambient temperature, and the current current is greater than or equal to the product of the second preset coefficient and the effective current, wherein the second preset coefficient is greater than or equal to the first preset coefficient.
[0065] Of course, it is also possible to judge based solely on the outdoor ambient temperature and the threshold. When the outdoor ambient temperature is less than the threshold, the target parameters are directly determined to meet the preset conditions.
[0066] As a preferred implementation of this application embodiment, the power correction includes: Adjust the current to the limit current, where the limit current = limit ratio * target current, the limit ratio is a positive number less than 1, and the target current is the current current or the effective current.
[0067] Preferably, such as Figure 5 As shown: S51: Record the number of adjustments. After each adjustment, the number of adjustments is incremented by 1, and the number of adjustments is cleared to zero when exiting power correction. S52: When power correction is required, if the number of adjustments is less than or equal to the preset number, the current is adjusted to the limit current. In one embodiment, the limit ratio remains constant during each adjustment, or the limit ratio decreases as the number of adjustments increases. This is because a large number of adjustments indicates that the current load is still very high after adjustment, thus requiring further reduction of the current.
[0068] S53: If the number of adjustments exceeds the preset number, then the current remains unchanged.
[0069] Of course, in practice, the limiting current = target current - fixed threshold.
[0070] As a preferred implementation of the embodiments of this application, it further includes: When performing power correction, the current is compensated every five time intervals, and the current value for each compensation is 1 / N, where N is the preset number of compensations.
[0071] Among them, power correction is exited after a preset number of continuous compensations; Alternatively, when performing power correction, if the duration of a continuous difference between the indoor ambient temperature and the set temperature that is greater than the preset difference exceeds the sixth preset duration, the limit ratio will be increased or power correction will be exited.
[0072] In one embodiment, such as Figure 6 As shown, it also includes: S61: After adjusting the current to the limit current, obtain the corrected operating effect parameters, which include any one of the following: current change, temperature difference and room temperature recovery rate; S62: Adjust the limit ratio based on the operating effect parameters.
[0073] For example, if the temperature difference increases after the current is adjusted to the limiting current, the value of the limiting ratio is increased; if the temperature difference decreases and the rate of decrease is greater than a threshold after the current is adjusted to the limiting current, the value of the limiting ratio is decreased.
[0074] In another embodiment, such as Figure 7 As shown, it also includes: S71: Obtain outdoor ambient temperature; S72: Determine a limiting ratio based on the outdoor ambient temperature, wherein the smaller the absolute value of the difference between the outdoor ambient temperature and the preset outdoor ambient temperature, the larger the limiting ratio.
[0075] Understandably, a curve or formula can be set to determine a limiting ratio for the absolute value of the difference between each outdoor ambient temperature and a preset outdoor ambient temperature. Alternatively, the outdoor ambient temperature can be pre-divided into multiple ranges, each corresponding to a limiting ratio. For example: a low-temperature range (< 18℃), a normal-temperature range (18~32℃), and a high-temperature range (> 32℃), with the power correction magnitude dynamically adjusted based on changes in the current ambient temperature and load current. For instance, in a high-temperature environment, if a continuous increase in load current is detected, a stricter power limiting strategy is adopted (e.g., Ilimited current = Ieffective (effective current) × 70%); in a normal-temperature environment, a milder limiting strategy is adopted (e.g., Ilimited current = Ieffective × 85%); and in a low-temperature environment, a moderate limiting strategy is adopted (e.g., Ilimited current = Ieffective × 80%).
[0076] In one embodiment, the effective current is a current value determined based on user settings or big data.
[0077] In another embodiment, such as Figure 4 As shown, the effective current is obtained using the following method: S41: After the air conditioner is started, a temperature difference value is obtained, wherein the temperature difference value is the absolute value of the difference between the indoor ambient temperature and the set temperature; S42: When the temperature difference is greater than or equal to the first preset temperature difference, the recording of valid current is enabled. When the recording of valid current is enabled: the current is sampled once every first preset time interval; when the difference between the current sampled this time and the current sampled last time is greater than or equal to the preset current difference, the current sampled this time is taken as the valid current.
[0078] In one embodiment, the first preset duration is a fixed duration.
[0079] In another embodiment, the first preset duration is determined based on the temperature difference and the temperature change rate, wherein the temperature change rate is the duration required for the indoor ambient temperature to change to a preset temperature value, and when the temperature change rate is constant, the larger the temperature difference, the smaller the first preset duration.
[0080] The correspondence between the temperature difference and the rate of temperature change and the first preset duration can be preset in advance, such as by using formulas, curves or tables.
[0081] In addition, it also includes: Obtain the operating mode of the air conditioner, the operating mode including heating mode and cooling mode; The first preset temperature difference is determined based on the operating mode, wherein the first preset temperature difference in heating mode is greater than the first preset temperature difference in cooling mode. This is because there is a certain error between the temperature obtained by the air conditioner sensor and the actual temperature in heating mode.
[0082] As a preferred implementation of the embodiments of this application, it further includes: The effective current is cleared when any of the following conditions are met: The device was not turned on again within the second preset time period; The effective current has not been updated for the third consecutive preset time period during operation; The temperature difference is detected to be less than or equal to a second preset temperature difference, wherein the second preset temperature difference is less than a first preset temperature difference.
[0083] The air conditioning power correction method provided in this application includes: when the current operating phase is a stable operating phase, determining and obtaining a corresponding target parameter, the target parameter being used to represent the current operating load; and when the target parameter meets preset conditions, performing power correction, the power correction being used to reduce the current. This application achieves dynamic and precise adjustment of air conditioning power by obtaining the target parameter characterizing the operating load in real time and performing power correction to reduce current when preset conditions are met. This not only effectively adapts to dynamic changes in the environment and power grid, improving power grid stability and system energy efficiency, but also avoids overload or frequent start-stop, improving user experience.
[0084] Example 3: Existing air conditioning systems generally employ fixed power control, failing to dynamically adjust based on changes in ambient temperature, user habits, and grid load. Under heavy load operation, air conditioners are prone to significant power fluctuations, impacting grid stability and making it difficult to balance user comfort with system energy efficiency. Traditional air conditioning control systems typically lack comprehensive consideration of key environmental parameters such as humidity, and their power correction mechanisms are simplistic, failing to achieve refined power control. Furthermore, current technologies lack adaptive adjustment mechanisms based on historical operating data and real-time grid conditions, resulting in sluggish system response, low energy efficiency, and a poor user experience when facing complex and changing usage scenarios.
[0085] To address the above problems, this application provides a specific method for correcting air conditioner power, the specific implementation of which is as follows: During operation, the air conditioner uses a built-in current sensor to monitor the unit's current in real time. Simultaneously, it acquires current ambient temperature data from indoor and outdoor temperature sensors to determine if it is operating under heavy load (a heavy load is determined when the difference between the indoor ambient temperature and the set temperature is 8 degrees Celsius or higher, or when the outdoor ambient temperature Theating outer ring ≥ X°C or Tcooling outer ring ≥ Y°C). When the system determines that it is in the initial operating phase after the air conditioner is turned on, it enters the power correction control phase to ensure the air conditioner operates under normal cooling / heating conditions.
[0086] The system records the operating current and writes it into a memory chip to build a historical operating data model, providing a basis for power correction when the air conditioner starts up next time. Based on the difference between the user-set temperature and the current indoor ambient temperature, the system determines whether power correction control is needed. If the power correction condition is triggered during multiple operations, the system gradually adjusts the current to prevent frequent power fluctuations from affecting the stability of the power grid.
[0087] The air conditioner employs a dynamic power correction algorithm, combined with a power grid load detection module, to obtain real-time power grid load status and dynamically adjust the air conditioner's operating power, thereby improving overall power grid stability. Simultaneously, the system learns user habits to predict power demand, enhancing its intelligence and improving the user experience.
[0088] In power correction control, the system employs a multi-level power correction mechanism. Based on changes in ambient temperature and load, multiple power correction levels are set, and power output is adjusted progressively to enhance the air conditioner's adaptability to different environmental conditions. The system also integrates a humidity sensor, combining temperature and humidity data to comprehensively determine whether power correction conditions are triggered, improving the accuracy of the judgment and user comfort.
[0089] In terms of control logic, the system employs a fuzzy logic algorithm to handle temperature differences, improving the flexibility and accuracy of correction judgments. Simultaneously, the system introduces an adaptive adjustment algorithm to dynamically adjust the power correction range based on actual operating results, making power regulation more intelligent and balancing user comfort with energy efficiency.
[0090] like Figure 8 As shown, it includes the following steps: Step 1: Determine whether the unit is in cooling or heating mode upon startup. When the air conditioner starts in cooling or heating mode, the system detects the difference ΔT between the indoor ambient temperature and the set temperature (T_innerloop - T_set for cooling, T_set - T_innerloop - T_compensation for heating). In heating mode, an additional T_compensation value needs to be subtracted because there is a deviation between the ambient temperature value sampled by the indoor ambient temperature sensor and the actual ambient temperature value (the air conditioner is positioned higher, hot air rises and cold air falls, so the temperature near the air conditioner is higher than the overall indoor ambient temperature during heating, thus requiring an additional compensation value to be subtracted). In cooling mode, cold air falls, and the temperature near the air conditioner is not significantly different from the indoor ambient temperature). To achieve better control, a compensation value needs to be subtracted in heating mode, and this value is generally 3 (but can also be 1 or 2).
[0091] If ΔT ≥ A (e.g., A=3℃), then the recording of the effective current I is enabled. The current is sampled every t1 time interval (t1=t-Δt, e.g., t=30 minutes). If the current It current ≥ the previous It-1 current + 1.0A, then the effective current I is refreshed and written to the memory chip.
[0092] If A-2℃ < △T < A, then maintain the detection state of the previous interval; during the first run, execute according to the recorded effective current of I.
[0093] If ΔT < A-2℃, then exit the recording and clear the effective current I.
[0094] The system dynamically adjusts whether to enter the power correction phase based on multiple factors such as temperature change trends, the magnitude of temperature differences, and the rate of change. For example, when the temperature difference approaches the threshold (i.e., when the load is large) and the rate of change is rapid, correction control is activated to prevent sudden load changes from impacting the power grid.
[0095] Specifically, Δt is determined using a fuzzy definition. The details are as follows: First, the rate of temperature change This refers to the time required for the indoor ambient temperature to change by 0.5℃ after the temperature enters the temperature band (i.e., 0.5℃ ≤ ΔT. Entering the temperature band means that the difference between the ambient temperature and the set temperature changes by 0.5℃ or more) or after the last fuzzy inference. A temperature change close to the set temperature is marked as "+" (T inner ring decreases for cooling, T inner ring increases for heating), and a temperature change far from the set temperature is marked as "-" (T inner ring increases for cooling, T inner ring decreases for heating).
[0096] The fuzzy definitions of the rate of change of temperature difference and the fuzzy definition of temperature difference are shown in Table 1: Table 1 The values of △t are shown in Table 2: Table 2 Additionally, a humidity sensor can be used to combine the overall temperature and humidity index (such as THI, thermal comfort index) to determine whether to enter the power correction phase. For example, when the overall temperature and humidity index exceeds a set threshold, the system determines that there is a risk of high-load operation and initiates power correction control.
[0097] Step 2: Power Correction Judgment During Operation During air conditioner operation, the system continuously determines whether the power correction conditions are met: a. If the outdoor ambient temperature T_heating outer ring ≥ X℃ or T_cooling outer ring ≥ Y℃, and the detected It current ≥ 80%I effective current, then the system enters the power correction stage; b. If T_heating outer ring < X℃ or T_cooling outer ring < Y℃, and the detected It current ≥ 90%I effective current, then the system enters the power correction stage. Otherwise, power correction will not be performed.
[0098] In other words, during the startup and operation phase, the temperature difference and temperature change rate are used to determine whether to perform power correction (step 1), while during the operation phase, the outdoor ambient temperature is used to determine whether to enter power correction.
[0099] Step 1 involves operating the unit for one hour after startup, while Step 2 involves operating it for one hour after startup. During the first hour, power adjustments are made based on temperature differences and the rate of temperature change to ensure the room temperature meets customer needs. This reduces the user's temperature adjustment requirements and consequently lowers the load on the air conditioner. After one hour, the higher the external ambient temperature, the greater the relative load. In other words, with the same compressor frequency, a higher external ambient temperature results in a higher overall load. For example, if the compressor frequency increases by 1Hz, it might only operate at 5W when the external ambient temperature is low, but could reach 20W when the external ambient temperature is high. Therefore, power adjustments need to be made based on the external ambient temperature.
[0100] Step 3: Power correction execution If the unit is turned on again within time t2 (e.g., t2 = 60 minutes), the air conditioner will operate at I limiting current = I effective current × a% (e.g., a = 85%). If the correction condition is triggered again during the operation of the power limit correction, the operation will be adjusted to b% and c% in sequence (e.g., b=75%, c=65%), with a maximum of 3 corrections. If the error is triggered more than 3 times consecutively, the last correction value will remain unchanged.
[0101] An adaptive adjustment mechanism is introduced during the power correction process. Based on the operational effects after each correction (such as current changes, user feedback, and room temperature recovery speed), the current limit ratio for the next correction is dynamically adjusted. For example, if user feedback indicates a slow cooling rate after a correction, the current limit ratio is appropriately reduced to restore some cooling capacity. Alternatively, if the user adjusts the set temperature, causing a larger difference between the set temperature and the ambient temperature, it indicates user dissatisfaction with the current performance, and the limit ratio is appropriately reduced. Similarly, the limit ratio is appropriately reduced when the current increases or the room temperature recovery speed slows down, and vice versa.
[0102] A module for detecting real-time grid load status is employed. When a high grid load is detected, the power correction is automatically increased, for example, adjusting the current limit (Ilimit) to Ieffective × 60%. As the grid load decreases, the power limit is gradually restored (for example, after a load decrease, the limit is initially restored to 65%; if the load continues to decrease after 30 minutes, it is restored to 70%; if the load does not increase after 30 minutes, it is restored to 80%, and so on, gradually restoring the power limit). This minimizes the impact on user experience. Grid load is represented by a load factor: Load factor = Average load / Maximum load × 100%. A load factor ≥ 85% indicates a high grid load.
[0103] During initial installation, the system obtains the city / region location via Wi-Fi, user input, or GPS, and accesses a local climate database (such as standard climate data from the China Meteorological Administration). It then divides the outdoor ambient temperature into multiple zones based on the region, such as a low-temperature zone (< 18℃), a normal-temperature zone (18~32℃), and a high-temperature zone (> 32℃). The system dynamically adjusts the power correction based on changes in the current ambient temperature and load current. For example, in a high-temperature environment, if a continuous increase in load current is detected, a stricter power limiting strategy is adopted (e.g., Ilimited current = Ieffective current × 70%); in a normal-temperature environment, a milder limiting strategy is adopted (e.g., Ilimited current = Ieffective current × 85%); and in a low-temperature environment, a moderate limiting strategy is adopted (e.g., Ilimited current = Ieffective current × 80%).
[0104] As shown in Table 3: Table 3 Step 4: Exit power correction limit During the correction operation, the I-limit current is compensated every t3 time interval (e.g., t3 = 30 minutes). After each compensation, I_compensated = I_limit current + 1 / NA. After N consecutive compensations, the correction state is exited. If there is still high demand during operation (the difference between the indoor ambient temperature and the set temperature is still large, such as 8 degrees or above, indicating that the user has a high demand for temperature adjustment and needs to ensure the heating / cooling effect), then part of the limiting current will be restored to ensure the cooling / heating effect.
[0105] Step 5: Clear the effective current of I If the device is not powered on again within time t2, then clear the effective current I. If the effective current I is not updated for a continuous time period t4 (e.g., t4 = 2 hours) during operation, it will be re-recorded in the next t1 cycle. If ΔT ≤ A-2℃ is detected, then clear the effective current I.
[0106] Step 6: Learn from user habits and intelligently predict power demand. By collecting information such as users' daily usage time, set temperature, and operating mode, a user habit model is established. Before the time when users are accustomed to using the air conditioner, the system activates a power correction mechanism in advance to optimize the initial operating power and avoid grid impact caused by sudden load increases.
[0107] In addition, machine learning algorithms can be introduced to optimize dynamic power correction strategies. Building upon the existing dynamic power correction algorithm, a machine learning algorithm is introduced to predict future power demand trends by analyzing long-term operating data and user behavior habits, and dynamically optimize the power correction strategy. The system can combine historical operating data, user settings, outdoor environmental changes, and other multi-dimensional data to build a predictive model, adjust power output in advance, reduce power fluctuations, and improve system response speed and user comfort.
[0108] Furthermore, applying the proposed solution to a modular air conditioning unit system supports the parallel operation of multiple air conditioners. Each air conditioner can operate independently or work collaboratively through a central control system, dynamically adjusting the operating power of each unit based on the overall ambient temperature, power grid load, and user needs, thereby enhancing system flexibility and scalability and achieving regional intelligent temperature control management.
[0109] Finally, it can also be combined with a multi-dimensional environmental sensing system using air quality sensors. Based on the existing temperature and humidity sensors, an air quality detection module is added to form a multi-sensor fusion system. The system integrates data such as temperature, humidity, and air pollutant concentrations to dynamically adjust power correction strategies. This not only improves user comfort but also enhances indoor air quality, achieving a smart air conditioning control solution that prioritizes both health and energy efficiency. For example, when air quality is poor or humidity is high, the user's need for improvement is greater, and the air conditioner needs to quickly improve user comfort and air quality, requiring a reduction in the power correction latency and an increase in power output. Conversely, if air quality is good, the user's need for improvement is less, allowing for a longer power correction latency and a reduction in power output.
[0110] The specific air conditioning power correction method provided in this application introduces a multi-level power correction mechanism, enabling the system to adjust power output in stages according to changes in ambient temperature and load current, thereby enhancing the adaptability and operational stability of the air conditioner under different operating conditions. A fuzzy logic algorithm is used to process temperature differences, improving the accuracy of power correction judgment and control flexibility. Integrating a humidity sensor and combining it with a comprehensive temperature and humidity index enables multi-dimensional environmental perception, improving the accuracy of power correction and thus enhancing user comfort. Through an adaptive adjustment algorithm, the system can dynamically optimize the correction range based on actual operating results, achieving self-optimization and intelligent adjustment. Simultaneously, combined with grid load detection and user habit learning functions, the system can proactively adjust power, effectively smoothing grid fluctuations and achieving energy-saving and consumption-reducing effects.

The temperature and humidity comprehensive index is greater than or equal to the corresponding preset value. The temperature and humidity comprehensive index is a parameter determined based on the indoor ambient temperature and indoor ambient humidity. The combined temperature and humidity index is less than the corresponding preset value, but the air quality index is greater than the preset value.
[0121] When the current operation phase is a stable operation phase, the target parameter satisfies the preset condition if any of the following conditions exist: The outdoor ambient temperature is greater than or equal to the preset outdoor ambient temperature, and the current current is greater than or equal to the product of the first preset coefficient and the effective current.
