[0002] Air conditioners of different horsepower are suitable for rooms of different sizes. However, if the relationship between air conditioner horsepower and room size is not understood, or if the air conditioner is moved to a different room, the air conditioner's horsepower may not match the room size, resulting in insufficient or excessive cooling capacity.

[0003] To address the issue of air conditioner cooling or heating temperatures failing to meet user needs, related technologies propose a control method, controller, and storage medium for correcting the set temperature of an air conditioner. The method includes: acquiring room parameter information where the air conditioner is located; correcting the set temperature of the air conditioner based on a steady-state temperature compensation value according to the room parameter information; and, if the corrected steady-state temperature compensation value still fails to meet user needs, retrieving the air conditioner's unsteady-state temperature compensation value and further correcting the set temperature based on the room parameter information.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

Therefore, this control method has relatively low reliability.

[0042] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0044] Unless otherwise stated, the term "multiple" means two or more.

[0045] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0046] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0047] The term "correspondence" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.

[0048] Related technologies propose a control method, controller, and storage medium for correcting the set temperature of an air conditioner. The method includes: acquiring room parameter information where the air conditioner is located; correcting the set temperature of the air conditioner based on a steady-state temperature compensation value according to the room parameter information; and, if the corrected steady-state temperature compensation value fails to meet the user's needs, retrieving the air conditioner's unsteady-state temperature compensation value and further correcting the set temperature based on the room parameter information.

[0049] While related technologies can correct the set temperature based on room parameters and commonly used steady-state temperature compensation values, and further correct the set temperature based on unsteady-state temperature compensation values ​​when the first temperature correction fails to meet user needs, thus satisfying the user's cooling or heating temperature requirements, the air conditioner may experience unstable operation when running at the set temperature corrected based on unsteady-state temperature compensation values. Therefore, this control method has relatively low reliability.

[0050] This disclosure provides a control method for an air conditioner, which improves the stability of the air conditioner's operation and enhances the reliability of the control method. This control method can be applied to an air conditioner, which adjusts its operating state based on environmental parameters. The air conditioner includes a processor and a memory storing program instructions. It may also include a communication interface and a bus. The processor, communication interface, and memory communicate with each other via the bus. The communication interface is used for information transmission.

[0051] Combination Figure 1 As shown, the control method of the air conditioner includes:

[0052] S101, the processor acquires environmental parameters, including ambient temperature.

[0053] S102, the processor obtains the actual working time based on the ambient temperature.

[0054] S103, the processor retrieves the theoretical working time from the database based on environmental parameters and set wind speed.

[0055] S104, the processor controls the operating status of the air conditioner based on the theoretical working time and the actual working time.

[0056] The air conditioner control method provided in this disclosure can adjust the air conditioner's operating state based on its theoretical and actual operating time. By adjusting the air conditioner's operating state, the problem of insufficient or excessive cooling capacity caused by a mismatch between the air conditioner's capacity and the room size is alleviated. Furthermore, compared to related technologies, it avoids using unsteady-state temperature compensation values ​​to correct the set temperature, thus mitigating the problem of unstable air conditioner operation and improving the reliability of the control method.

[0057] Optionally, the step of obtaining the actual working time based on the ambient temperature includes: calculating ΔT = (T0 - T) / N to obtain the adjustment temperature difference ΔT; calculating T s =T + ΔT, to obtain the adjustment temperature T s When the ambient temperature T reaches the adjustment temperature T s Under these conditions, the actual working time is obtained; where T0 represents the set temperature of the air conditioner, T represents the ambient temperature, and N is a constant.

[0058] In this embodiment, T represents the ambient temperature, which is acquired in real time. T0 represents the set temperature of the air conditioner, which is set by the user or automatically set by the air conditioner after obtaining a suitable temperature from an associated device. The associated device of the air conditioner can communicate with the air conditioner via a wireless network or Bluetooth. For example, the associated device of the air conditioner is one of a mobile phone, a television, or a computer. Taking a mobile phone as an example, the mobile phone connects to the air conditioner via Bluetooth to achieve communication, or the mobile phone and the air conditioner are connected to the same wireless network to achieve communication. The mobile phone has software adapted to the air conditioner downloaded. The software obtains the temperature of the current area on the mobile phone, determines the temperature at which the human body feels comfortable, and sends the comfortable temperature information to the air conditioner via Bluetooth or wireless network. The air conditioner sets the temperature according to the received comfortable temperature. The actual working time refers to the actual time it takes for the ambient temperature T to reach the set temperature T by running the air conditioner. s The theoretical operating time refers to the time required for the air conditioner to operate stably under the current environmental parameters until the ambient temperature T reaches the set temperature T. sThe required operating time. The theoretical operating time can be retrieved from the database based on environmental parameters and the set fan speed. By setting the fan speed, the air conditioner can operate stably, and the corresponding database is determined. The database stores the theoretical operating time required for adjusting the temperature difference ΔT under different environmental parameter conditions at the current set fan speed. Since the actual operating time is based on parameters obtained from the actual operating state of the air conditioner, and the theoretical operating time is based on parameters obtained from the stable operating state of the air conditioner, the operating state of the air conditioner is adjusted by combining the theoretical and actual operating times. Compared with related technologies, this avoids the use of unsteady parameters, thus improving the stability of the air conditioner's operating state.

[0059] Optionally, N ≥ 2.

[0060] In this embodiment, by limiting N≥2, the adjustment temperature difference ΔT=(T0-T) / N is defined, and the adjustment temperature T s =T + ΔT, allowing the air conditioner to acquire multiple actual operating times during the process from start-up to when the ambient temperature T reaches the set temperature T0, thus enabling multiple adjustments to the air conditioner's operating status. For example, N can take values ​​of 2, 3, 4, 5, 6, 7, 8, 9, and 10. Taking an ambient temperature T of 32℃, a set temperature T0 of 24℃, and N of 10 as an example, temperature difference adjustment is performed. Due to the adjustment temperature T s =T + ΔT, where the ambient temperature T is obtained in real time, so the corresponding T s1 =32℃ - 0.8℃ = 31.2℃. Obtain an actual working time when the ambient temperature drops from 32℃ to 31.2℃. T s2 =31.2℃ - 0.8℃ = 30.4℃. The actual operating time is obtained when the ambient temperature drops from 31.2℃ to 30.4℃. By enabling the air conditioner to perform multiple operating state adjustments as the ambient temperature T reaches the set temperature T0, the reliability of the control method is further improved.

[0061] Combination Figure 2 As shown in the embodiments of this disclosure, another method for controlling an air conditioner includes:

[0062] S201, the processor acquires environmental parameters, including ambient temperature.

[0063] S202, the processor obtains the actual working time based on the ambient temperature.

[0064] S203, the processor retrieves the theoretical working time from the database based on environmental parameters and set wind speed.

[0065] S204, the processor controls the air conditioner to operate in the first correction mode based on the theoretical working time and the actual working time.

[0066] S205, if the air conditioner cannot meet the user's needs after being corrected by the first correction mode, the processor controls the air conditioner to run in the second correction mode based on the theoretical working time, the actual working time and the first correction mode.

[0067] The air conditioner control method provided in this disclosure can adjust the air conditioner's operating state by controlling it to operate in a first correction mode based on theoretical and actual operating time. This alleviates the problem of insufficient or excessive cooling capacity caused by a mismatch between the air conditioner's capacity and the room size. Furthermore, if the air conditioner, after correction using the first correction mode, fails to meet user needs, or if changes in environmental parameters render the corrected air conditioner unsuitable for the current environmental conditions, the environmental parameters can be re-acquired. Based on the theoretical and actual operating time and the first correction mode, the air conditioner can be controlled to operate in a second correction mode to adjust its operating state. This ensures the air conditioner's operating state meets user needs under the new environmental parameter conditions, thereby improving the air conditioner's applicability and further enhancing the reliability of the control method.

[0068] Optionally, the step of controlling the air conditioner to operate in the first correction mode according to the theoretical working time and the actual working time includes: controlling the air conditioner to operate in the frequency correction mode when t≤at0; or controlling the air conditioner to operate in the temperature correction mode when t≥bt0; or controlling the air conditioner to maintain the current operating state when at0≤t≤bt0; where t represents the actual working time, t0 represents the theoretical working time, and a and b are constants.

[0069] In this embodiment, the air conditioner can be further controlled in different correction modes based on the theoretical and actual operating times to alleviate either insufficient or excessive cooling capacity. Specifically, when t ≤ at0, the air conditioner's capacity meets the current space requirements. Since t ≤ at0, this indicates excessive cooling capacity, and the air conditioner's operating frequency correction mode is controlled to alleviate this problem. When at0 ≤ t ≤ bt0, the air conditioner's capacity is compatible with the current space, and no adjustment to the air conditioner's operating state is needed; the air conditioner is controlled to maintain its current operating state. When t ≥ bt0, the air conditioner's capacity does not meet the current space requirements. Since t ≥ bt0, this indicates insufficient cooling capacity, and the air conditioner's operating temperature correction mode is controlled to alleviate this problem. By comparing the actual and theoretical operating times, the air conditioner's operating state is controlled under different conditions to improve the control accuracy of the air conditioner.

[0070] Alternatively, 0.94≤a≤0.96, 1.04≤b≤1.05.

[0071] In this embodiment, ideally, the actual working time equals the theoretical working time, and the air conditioner's operating state is adapted to the current space, eliminating the need for adjustments. By limiting 0.94 ≤ a ≤ 0.96 and 1.04 ≤ b ≤ 1.05, the air conditioner's capacity is made closer to the ideal situation, thereby alleviating the problems of energy waste due to excessive cooling capacity or user experience issues due to insufficient cooling capacity. For example, the values ​​of a are 0.94, 0.95, and 0.96, and the values ​​of b are 1.04, 1.05, and 1.06.

[0072] Optionally, the steps of controlling the air conditioner's operating frequency correction mode include: adjusting the air conditioner's set frequency based on the theoretical operating time and the actual operating time; obtaining a frequency correction scheme when at0≤t≤bt0; and correcting the air conditioner's set frequency based on the obtained frequency correction scheme.

[0073] In this embodiment, the air conditioner's set frequency is preset by technicians or set by the user through the air conditioner's associated devices. When the air conditioner's cooling capacity is excessive, the set frequency is adjusted based on theoretical and actual operating times to alleviate this problem. This adjustment continues until at0 ≤ t ≤ bt0, at which point a frequency correction scheme is obtained, and the air conditioner's set frequency is then corrected according to this scheme. Compared to related technologies, this method achieves air conditioner set frequency correction, alleviates excessive cooling capacity, and avoids energy waste.

[0074] Optionally, the step of adjusting the set frequency of the air conditioner based on the theoretical working time and the actual working time includes: calculating Δt = t0 - t to obtain the time difference Δt; and adjusting the set frequency of the air conditioner based on Δt.

[0075] In this embodiment, a preset mapping relationship exists between the duration difference Δt and the adjustment value of the air conditioner's set frequency. The larger the duration difference Δt, the larger the adjustment value of the air conditioner's set frequency. By calculating Δt = t0 - t, the air conditioner's set frequency is adjusted according to Δt, ensuring that at0 ≤ t ≤ bt0, in order to obtain a frequency correction scheme. For example, if the duration difference Δt = 10s, the air conditioner's set frequency is reduced by 2Hz according to the preset mapping relationship between the duration difference Δt and the air conditioner's set frequency adjustment value. If the duration difference Δt = 20s, the air conditioner's set frequency is reduced by 4Hz according to the preset mapping relationship between the duration difference Δt and the air conditioner's set frequency adjustment value.

[0076] Optionally, the step of adjusting the set frequency of the air conditioner according to the theoretical working time and the actual working time includes: reducing the set frequency of the air conditioner by c%, where c is a constant, when t≤at0.

[0077] In this embodiment, when t ≤ at0, the air conditioner's set frequency is adjusted by decreasing the current set frequency by c% each time, bringing the air conditioner's operating state closer to the ideal operating state. For example, if c is 10 and the current set frequency is 45Hz, since t ≤ at0, the set frequency is decreased by 45Hz × 10% = 4.5Hz, adjusting the set frequency to 40.5Hz. If at0 ≤ t ≤ bt0 is still not satisfied, the set frequency is decreased by 40.5Hz × 10% = 4.05Hz, adjusting the set frequency to 36.45Hz. By gradually reducing the set frequency by c% each time, the adjustment value of the air conditioner's set frequency is gradually reduced, further improving the control accuracy of the air conditioner.

[0078] Optionally, 8 ≤ c ≤ 12.

[0079] In this embodiment, the value of c is limited to 8 ≤ c ≤ 12 to avoid c being too large, which would hinder the precise adjustment of the air conditioner's operating frequency, or c being too small, which would increase the calculation process or operating steps of the air conditioner. For example, the value of c is 8, 9, 10, 11, or 12.

[0080] It should be noted that the preset mapping relationship between the duration difference Δt and the adjustment value of the air conditioner's set frequency, as well as the specific values ​​of a, b, and c, need to be set by researchers based on the actual air conditioner specifications and dimensions, and are not specified here.

[0081] Furthermore, when at0≤t≤bt0, the obtained frequency correction scheme needs to be specifically determined based on the theoretical working time and the actual working time, and the method of adjusting the air conditioner's set frequency.

[0082] Specifically, based on the theoretical and actual operating times, the method for adjusting the air conditioner's set frequency is to calculate Δt = t0 - t to obtain the time difference Δt. Based on Δt, the frequency correction scheme obtained by adjusting the air conditioner's set frequency is the adjusted value of the air conditioner's set frequency. For example, if the time difference Δt = 20 seconds, according to the preset mapping relationship between the time difference Δt and the air conditioner's set frequency adjustment value, the air conditioner's set frequency is reduced by 4 Hz. After the air conditioner's set frequency is reduced by 4 Hz, at0 ≤ t ≤ bt0, and the obtained frequency correction scheme is -4 Hz. Therefore, the air conditioner will subsequently operate at the set frequency reduced by 4 Hz.

[0083] Specifically, based on the theoretical and actual operating times, the method for adjusting the air conditioner's set frequency is as follows: When t ≤ at0, the air conditioner's operating power is reduced by c%. The resulting frequency correction scheme is the ratio of the corrected set frequency to the original set frequency. For example, c is 10, the original set frequency was 45Hz, and after two frequency adjustments, the set frequency is 36.45Hz. When operating at a set frequency of 36.45Hz, satisfying at0 ≤ t ≤ bt0, the resulting frequency correction scheme is... Then the actual operating frequency of the air conditioner will be 81% of the set frequency.

[0084] Optionally, the steps of controlling the air conditioner's operating temperature correction mode include: adjusting the air conditioner's set temperature based on environmental parameters and air conditioner operating parameters; obtaining a temperature correction scheme when at0≤t≤bt0; and correcting the air conditioner's set temperature based on the obtained temperature correction scheme.

[0085] In this embodiment, when the air conditioner's cooling capacity is insufficient, the set temperature of the air conditioner is adjusted based on environmental parameters and the air conditioner's operating parameters to meet the user's cooling needs. This adjustment continues until at0 ≤ t ≤ bt0, at which point a temperature correction scheme is obtained, and the air conditioner's set temperature is then adjusted according to this scheme. Compared to related technologies, this approach avoids the use of unsteady-state parameters, improving the stability of the air conditioner's operating state and the reliability of the control method.

[0086] Optionally, the step of adjusting the air conditioner's set temperature based on environmental parameters and air conditioner operating parameters includes: calculating T... c =T + ΔT - (n-1) × 1℃, to obtain the corrected temperature T c Adjust the air conditioner's set temperature according to the corrected temperature; where T represents the ambient temperature, ΔT represents the set temperature difference, and n represents the number of corrections.

[0087] In this embodiment, the air conditioner operating parameters include n, where n represents the number of corrections. T represents the ambient temperature, and ΔT represents the set temperature difference. The correction temperature T is calculated... c =T + ΔT - (n-1) × 1℃. Based on the corrected temperature, adjust the air conditioner's set temperature to ensure at0 ≤ t ≤ bt0, thus obtaining a temperature correction scheme. For example, if the ambient temperature T is 32℃, the set temperature T0 is 24℃, and N is 10, then the set temperature difference ΔT = -0.8℃, and the set temperature T... s1 =32℃ - 0.8℃ = 31.2℃. When the ambient temperature drops from 32℃ to 31.2℃, the actual operating time t1 is obtained. Since t1 ≥ bt0, the air conditioner operates in temperature correction mode, performing the first temperature correction. At this time, n is set to 1, and the ambient temperature T = T s1=31.2℃. Therefore, the corrected temperature T c1 =T + ΔT - (n-1) × 1℃ = 31.2℃ - 0.8℃ = 30.4℃, adjust the temperature T s2 The numerical value is replaced with the corrected temperature T. c1 The air conditioner operates at a set temperature of 30.4℃. The actual operating time t2 is recorded when the ambient temperature drops from 31.2℃ to 30.4℃. When t2 ≥ bt0, a second temperature correction is performed, where n is set to 2, and the ambient temperature T = T0. s2 =31.2℃. Therefore, the corrected temperature T c2 =T + ΔT - (n-1) × 1℃ = 30.4℃ - 0.8℃ - 1℃ = 28.6℃, adjust the temperature T s3 The numerical value is replaced with the corrected temperature T. c2 The air conditioner operates at a set temperature of 28.6℃. The temperature correction scheme is obtained when at0 ≤ t ≤ vt0.

[0088] Furthermore, when at0 ≤ t ≤ bt0, the obtained temperature correction scheme is as follows: ΔT c This represents the temperature correction amount, in °C. For example, when the ambient temperature drops from 30.4 °C to 28.6 °C, the actual working time t3 is obtained, where at0 ≤ t3 ≤ bt0. In this case, n = 2, and the obtained temperature correction amount is... Then the actual operating temperature of the air conditioner will be 1°C lower than the set temperature.

[0090] S301, the processor acquires environmental parameters, including ambient temperature.

[0093] S304, when t≤at0, the processor controls the air conditioner's operating frequency correction mode.

[0094] S305, when at0≤t≤bt0, the processor controls the air conditioner to maintain its current operating state.

[0095] S306, when t≥bt0, the processor controls the air conditioner to provide feedback decision information, which is whether to enter the temperature correction mode.

[0096] S307, when the temperature correction mode is entered, the processor controls the air conditioner to run in temperature correction mode.

[0097] S308, without entering temperature correction mode, the processor controls the air conditioner to stop running.

[0098] S309, if the air conditioner cannot meet the user's needs after being corrected by the first correction mode, the processor controls the air conditioner to run in the second correction mode based on the theoretical working time, the actual working time and the first correction mode.

[0099] Where t represents the actual working time, t0 represents the theoretical working time, and a and b are constants.

[0100] The air conditioner control method provided in this disclosure can provide decision information to the user before entering the temperature correction mode (t≥bt0), allowing the user to decide whether to enter the temperature correction mode. In the current market, products typically offer a return / exchange period, meaning users can return or exchange goods within a certain timeframe after purchase. When t≥bt0, it indicates that the air conditioner's capacity is insufficient for the current space. By controlling the air conditioner to provide decision information to the user when t≥bt0, the user can decide whether to exchange the product within the return / exchange period. If the user decides to exchange the product, they can choose not to enter the temperature correction mode, and the air conditioner will stop operating, allowing the user to contact the seller promptly for exchange or return processing. By controlling the air conditioner to provide decision information to the user when t≥bt0, the air conditioner is adapted to the after-sales service of the current market.

[0101] Controlling the air conditioner to provide feedback on decision-making information can be done through voice prompts or by sending the information to connected devices, such as mobile phones. The specific feedback method will be configured by technicians based on the actual air conditioner; no specific rules are provided here.

[0102] Optionally, environmental parameters may also include the ambient humidity and room size of the room where the air conditioner is located.

[0103] In this embodiment, environmental parameters also include the ambient humidity and room area of ​​the room where the air conditioner is located. The theoretical and actual operating times of the air conditioner differ under different ambient humidity levels. Higher humidity means more moisture in the air, and water has a higher specific heat capacity, leading to a decrease in the air's heat transfer capacity, thus resulting in longer theoretical and actual operating times for the air conditioner. Similarly, the theoretical and actual operating times of the air conditioner differ depending on the room area. Larger rooms require more cooling capacity to reach the set temperature, thus resulting in longer theoretical and actual operating times for the air conditioner.

[0104] Optionally, the step of controlling the air conditioner to operate in the second correction mode according to the theoretical working time, the actual working time, and the first correction mode includes: controlling the air conditioner to operate in the frequency correction mode when t≥bt0 and the first correction mode is the frequency correction mode; or controlling the air conditioner to operate in the temperature correction mode when t≥bt0 and the first correction mode is the temperature correction mode or the first correction mode is not operating; or controlling the air conditioner to maintain the current operating state when at0≤t≤bt0.

[0105] In this embodiment, when t ≥ bt0, it indicates that the air conditioner's cooling capacity is insufficient under the new environmental parameters. When the first correction mode is the frequency correction mode, the air conditioner is controlled to operate in the frequency correction mode, and the set frequency of the air conditioner is readjusted to adapt the air conditioner's operating state to the new environmental state. It should be noted that the specific steps of the frequency correction mode in the second correction mode are the same as those in the first correction mode.

[0106] Specifically, in the first correction mode, the method for adjusting the air conditioner's set frequency based on the theoretical and actual working hours is to calculate the time difference Δt = t0 - t, and then adjust the air conditioner's set frequency according to Δt. In the second correction mode, the method for adjusting the air conditioner's set frequency based on the theoretical and actual working hours is to calculate the time difference Δt = t0 - t, and then adjust the air conditioner's set frequency according to Δt. Specifically, in the first correction mode, the method for adjusting the air conditioner's set frequency based on the theoretical and actual working hours is to reduce the air conditioner's operating power by c% when t ≤ at0. In the second correction mode, the method for adjusting the air conditioner's set frequency based on the theoretical and actual working hours is to increase the air conditioner's operating power by c% when t ≤ at0.

[0107] For example, in the first correction mode, the calculated time difference Δt = t0 - t, where Δt = 20s. Based on Δt, the obtained frequency correction scheme is -4Hz, and the air conditioner operates at a frequency 4Hz lower than the set frequency. After the air conditioner is moved to another room, the environmental parameters change, and the air conditioner corrected by the first correction mode is no longer suitable for the current environmental parameters. At this time, t ≥ bt0, and the air conditioner is controlled to run in the second correction mode, which is the frequency correction mode. The calculated time difference Δt = t0 - t, where Δt = -10s. Based on Δt, the obtained frequency correction scheme is 2Hz, and the air conditioner operates at a frequency 2Hz higher than the set frequency.

[0108] When the first correction mode is the temperature correction mode or is not activated, the air conditioner is controlled to operate in temperature correction mode to adjust the set temperature, adapting its operation to the new environmental conditions. When at0 ≤ t ≤ bt0, the air conditioner's operation is adapted to the new environmental parameters, requiring no further adjustment and maintaining its current state. If the air conditioner, after correction using the first correction mode, fails to meet user needs, or if changes in environmental parameters render it unsuitable for the current environment, the air conditioner's operating frequency correction mode is activated based on theoretical operating time, actual operating time, and the first correction mode. This corrects the set frequency, or the air conditioner's set temperature correction mode is activated to adjust the set temperature, mitigating insufficient or excessive cooling capacity under the new environmental conditions.

[0109] Furthermore, when t≥bt0 and the first correction mode is the frequency correction mode, the air conditioner is controlled to operate in the frequency correction mode. When the air conditioner's set frequency is corrected through the frequency correction mode to reach its maximum value, but it still cannot satisfy at0≤t≤bt0, the second correction mode is controlled to switch to the temperature correction mode.

[0110] In this embodiment, if the air conditioner's set frequency reaches its maximum value but still cannot satisfy at0≤t≤bt0, the second correction mode is switched to a temperature correction mode to avoid instability caused by excessively high air conditioner operating frequency. Simultaneously, by switching from the second correction mode to the temperature correction mode, the air conditioner's operating state is further adjusted to ensure that its cooling capacity meets the user's needs.

[0111] Optionally, the step of controlling the air conditioner to operate in the second correction mode based on the theoretical working time, the actual working time, and the first correction mode further includes: canceling the correction of the first correction mode when t≤at0; and controlling the air conditioner to operate in the second correction mode based on the theoretical working time and the actual working time.

[0112] In this embodiment, t≤at0 indicates that the air conditioner's cooling capacity is excessive under the new environmental parameters. By canceling the first mode's correction of the air conditioner, the air conditioner is controlled to operate in the second correction mode based on the theoretical and actual working time, thereby readjusting the air conditioner's operating state to adapt it to the new environmental state.

[0113] Combination Figure 4 As shown in the embodiments of this disclosure, another method for controlling an air conditioner includes:

[0114] S401, the processor acquires environmental parameters, including ambient temperature.

[0115] S402, the processor obtains the actual working time based on the ambient temperature.

[0116] S403, the processor retrieves the theoretical working time from the database based on environmental parameters and set wind speed.

[0117] S404, the processor controls the air conditioner to operate in the first correction mode based on the theoretical working time and the actual working time.

[0118] S405, if the air conditioner cannot meet the user's needs after being corrected by the first correction mode, the processor controls the air conditioner to run the second correction mode based on the theoretical working time, the actual working time and the first correction mode.

[0119] S406, when both the first correction mode and the second correction mode are in temperature correction mode, the processor controls the air conditioner to run the first warning message.

[0120] S407, if the first correction mode is not running and the second correction mode is the temperature correction mode, the processor controls the air conditioner to run the second warning message.

[0121] The air conditioner control method provided in this embodiment can control the air conditioner to issue warning messages according to a first correction mode and a second correction mode, reminding the user that the current air conditioner is operating in a low-temperature air supply mode and that the user should not approach the air conditioner vent to avoid discomfort. The warning message can be delivered via audio prompts or by sending a warning message to associated devices of the air conditioner.

[0122] Furthermore, the warning level of the first warning message is higher than that of the second warning message. For example, when the warning method is an audio prompt, the warning frequency of the first warning message is higher than that of the second warning message. When the warning method is sending a warning message to the associated device of the air conditioner, the content of the first warning message is "The current operating status of the air conditioner is low temperature air supply; please avoid being within 2 meters of the air conditioner vent," and the content of the second warning message is "The current operating status of the air conditioner is low temperature air supply; please avoid being within 1 meter of the air conditioner vent."

[0123] Optionally, the control method for the air conditioner further includes: when the first correction mode is a temperature correction mode and the second correction mode is not running, controlling the air conditioner to run a second warning message; when the first correction mode is a frequency correction mode and the second correction mode is a temperature correction mode, controlling the air conditioner to run a third warning message.

[0124] In this embodiment, the warning level of the second warning message is greater than that of the third warning message. For example, when the warning method is an audio prompt, the warning frequency of the second warning message is greater than that of the third warning message. When the warning method is sending a warning message to the associated device of the air conditioner, the content of the second warning message is: "The current operating state of the air conditioner is low temperature air supply; please avoid approaching within 1 meter of the air conditioner vent." The content of the third warning message is: "The current operating state of the air conditioner is low temperature air supply; please avoid approaching within 0.5 meters of the air conditioner vent."

[0125] It should be noted that the specific warning method, content, and level of warning information shall be set by the technicians based on the actual operating status of the air conditioner, and no specific rules shall be set here.

[0126] Combination Figure 5 As shown, this embodiment of the present disclosure provides a control device 50 for an air conditioner, including an acquisition module 510, a calculation module 520, a retrieval module 530, and an operation module 540. The acquisition module 510 is configured to acquire environmental parameters, including ambient temperature; the calculation module 520 is configured to acquire the actual working time based on the ambient temperature; the retrieval module 530 is configured to retrieve the theoretical working time from a database based on the environmental parameters and a set fan speed; and the operation module 540 is configured to control the operating state of the air conditioner based on the theoretical working time and the actual working time.

[0127] The control device 50 for an air conditioner provided in this embodiment can acquire environmental parameters, obtain the actual operating time based on the switching parameters, and retrieve the theoretical operating time according to the environmental parameters and the set fan speed. Based on the theoretical and actual operating times of the air conditioner, the operating state of the air conditioner can be adjusted. Compared with related technologies, this avoids using unsteady-state temperature compensation values ​​to correct the set temperature, alleviating the problem of unstable air conditioner operation. Furthermore, by adjusting the operating state of the air conditioner, the problem of insufficient or excessive cooling capacity caused by a mismatch between the air conditioner's capacity and the room size is alleviated, improving the reliability of the control method.
