Description

Technical Field

[0001] This application relates to the field of air conditioning, and more specifically, to a control method, apparatus, air conditioner, and storage medium for an air conditioner. Background Technology

[0002] Air conditioners are indispensable household appliances in modern life. Users can use air conditioners to adjust and control parameters such as temperature, humidity, and airflow within buildings or structures, thereby providing a more comfortable living environment. When an air conditioner is running, the compressor is controlled by a control device. This control device generates a significant amount of heat during compressor operation; if not dissipated in time, it can cause damage to the control device.

[0003] In related solutions, the temperature of the controller can be detected. When the temperature of the controller reaches a temperature threshold, the operating frequency of the compressor is reduced. After the temperature drops, the operating frequency of the compressor is increased again. This control method requires frequent control of the compressor to increase and decrease the frequency, which reduces the cooling or heating capacity and reduces user comfort. Summary of the Invention

[0004] This application provides a control method, device, air conditioner, and storage medium for an air conditioner. The method cools the control device by increasing the speed of the circulating fan, avoiding temperature changes in the air conditioner's operating space caused by reducing the compressor's operating frequency. While reducing the temperature of the control device, it ensures the user's comfort.

[0005] In a first aspect, a control method for an air conditioner is provided, applied to a controller of the air conditioner. The controller is installed within an electronic component cavity of the air conditioner. The air conditioner also includes a circulating fan, with the circulating fan and the electronic component cavity located in an inner air duct of the air conditioner. The air conditioner also includes a compressor located in an outer air duct of the air conditioner. The electronic method includes: during the operation of the compressor, controlling the circulating fan to operate at a first speed based on a first indoor temperature of the air conditioner's operating space, and obtaining a first operating temperature of the controller; if the first operating temperature is greater than a first temperature threshold, controlling the circulating fan to enter a fan speed mode, and controlling the circulating fan to operate at a second speed; obtaining a second operating temperature of the controller; if the second operating temperature is greater than the first temperature threshold, and the first operating time of the second operating temperature being greater than the first temperature threshold is greater than a first duration threshold, controlling the circulating fan to operate at a third speed, wherein the first speed is less than the second speed, and the second speed is less than the third speed.

[0006] Secondly, an apparatus for controlling an air conditioner is provided, the apparatus comprising:

[0007] The acquisition unit is used to control the circulating fan to run at a first speed based on the first indoor temperature of the air conditioner's operating space during the process of controlling the compressor operation, and to acquire the first operating temperature of the control device.

[0008] The first control unit is used to control the circulating fan to enter the air-raising mode and control the circulating fan to run at the second speed if the first operating temperature is greater than the first temperature threshold.

[0009] The second control unit is used to obtain the second operating temperature of the controller. If the second operating temperature is greater than the first temperature threshold and the first operating time of the second operating temperature being greater than the first temperature threshold is greater than the first duration threshold, then the circulating fan is controlled to operate at a third speed, where the first speed is less than the second speed and the second speed is less than the third speed.

[0010] Thirdly, an air conditioner is provided, comprising: a memory for storing executable program code; and a processor for calling and running the executable program code from the memory, causing the air conditioner to perform the method described in the first aspect or any possible implementation thereof.

[0011] Fourthly, a computer program product is provided, comprising: computer program code, which, when run on a computer, causes the computer to perform the methods described in the first aspect or any possible implementation thereof.

[0012] Fifthly, a computer-readable storage medium is provided that stores computer program code, which, when executed on a computer, causes the computer to perform the methods described in the first aspect or any possible implementation thereof.

[0013] In this embodiment, when the first operating temperature of the controller is detected to be greater than a first temperature threshold during compressor operation, the circulating fan is controlled to operate at a second speed. If the second operating temperature of the controller is again detected to be greater than the first temperature threshold, and the first operating time of the second operating temperature being greater than the first temperature threshold is greater than a first duration threshold, the circulating fan is controlled to operate at a third speed. Initially, when the first operating temperature of the controller is detected to be high, the operating temperature of the controller is reduced by increasing the speed of the circulating fan. Subsequently, if the second operating temperature of the controller is still detected to be higher than the first temperature threshold, and the second operating temperature remains higher than the first temperature threshold, the speed of the circulating fan is increased again, controlling the circulating fan to operate at the third speed. This method of increasing the speed of the circulating fan cools the controller, avoiding temperature changes in the air conditioner's operating space due to reducing the compressor's operating frequency. While reducing the temperature of the controller, user comfort is ensured. Attached Figure Description

[0021] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0022] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0023] Figure 1 This is a structural schematic diagram of an air conditioner provided in an embodiment of this application. For an integrated air conditioner (an air conditioning system in which all operating components such as the condenser, evaporator, compressor, and expansion valve are integrated into a single casing, wherein the compressor 1, outdoor fan 2, first heat exchanger 3, and indoor return air vent 10 are installed in the outer air duct of the air conditioner; the second heat exchanger 4, circulating fan 5, indoor air outlet 6, electronic component cavity 7, and outdoor ventilation vent 8 are located in the inner air duct of the air conditioner), as...Figure 1 As shown. The air conditioner can operate in cooling mode, heating mode, and fan mode. In cooling mode, the first heat exchanger acts as a condenser, and the second heat exchanger acts as an evaporator. In heating mode, the first heat exchanger acts as an evaporator, and the second heat exchanger acts as a condenser. In fan mode, the first heat exchanger, the second heat exchanger, the outdoor fan, and the compressor are not running. Air entering from the indoor return air vent passes through the inner and outer partitions 9 and the second heat exchanger, and then, along with air entering from the outdoor vent, is circulated back to the indoor space via the indoor air outlet through the circulating fan. In this embodiment, the air conditioner's electronic components include a controller, which controls the operation of the compressor, the first heat exchanger, the second heat exchanger, the outdoor fan, and the circulating fan. The electronic components also include a heat sink 11 for dissipating heat from the electronic component cavity, which can also receive commands from the controller. During compressor operation, the controller generates a large amount of heat; if this heat cannot be dissipated, the controller will be damaged.

[0024] In related technical solutions, when the operating temperature of the controller is determined to be too high by the thermistor of the controller, the operating frequency of the compressor is reduced to reduce the heat generated by the controller and lower the operating temperature of the controller. However, this method requires frequent control of the compressor to increase and decrease the operating frequency, which affects the operation of the compressor and reduces the user's comfort.

[0025] In this embodiment, when the first operating temperature of the controller is detected to be greater than a first temperature threshold during compressor operation, the circulating fan is controlled to run at a second speed. If the second operating temperature of the controller is again detected to be greater than the first temperature threshold, and the first operating time of the second operating temperature being greater than the first temperature threshold is greater than a first duration threshold, the circulating fan is controlled to run at a third speed. When the first operating temperature of the controller is initially detected to be high, the operating temperature of the controller is reduced by increasing the speed of the circulating fan. Subsequently, if the second operating temperature of the controller is still detected to be higher than the first temperature threshold, and the second operating temperature remains higher than the first temperature threshold, the speed of the circulating fan is increased again, controlling the circulating fan to run at the third speed. This method of increasing the speed of the circulating fan cools the controller, avoiding temperature changes in the air conditioner's operating space due to reducing the compressor's operating frequency. While reducing the temperature of the controller, user comfort is ensured.

[0026] based on Figure 1 The structural diagram shown below will be combined with... Figures 2-5 The control method for the air conditioner provided in the embodiments of this application will be described in detail.

[0027] Please see Figures 2-5This is a flowchart illustrating a control method for an air conditioner provided in an embodiment of this application. Figures 2-5 As shown, the method in this application embodiment may include the following steps S101-S103.

[0028] S101, during the process of controlling the operation of the compressor, the circulating fan is controlled to run at a first speed based on the first indoor temperature of the air conditioner's working space, and the first operating temperature of the control device is obtained;

[0029] In one embodiment, while controlling the operation of the compressor, the controller also controls the circulating fan to run at a first speed according to the first indoor temperature of the air conditioner's operating space (indoors). The controller can also control the operation of the compressor based on the first indoor temperature, or it can control the operation of the compressor according to a preset frequency. This is not limited here.

[0030] It is understandable that during the operation of the compressor controlled by the controller, the temperature of the controller may rise due to conductivity. In order to avoid the controller temperature from becoming too high, it is necessary to obtain the first operating temperature of the controller during the operation of the compressor, and determine whether the temperature of the controller needs to be reduced based on the obtained first operating temperature.

[0031] S102, if the first operating temperature is greater than the first temperature threshold, control the circulating fan to enter the air-raising mode and control the circulating fan to run at the second speed;

[0032] In one embodiment, when a first operating temperature is detected to be higher than a first temperature threshold, the circulating fan is controlled to enter the fan-up mode. After entering the fan-up mode, the circulating fan operates at a second speed. The fan-up mode is a mode in which the circulating fan is controlled to start cooling when the temperature of the control device is detected to be higher than the first temperature threshold during the operation of the air conditioner.

[0033] It is understandable that the circulating fan operates at a first speed during compressor operation. Therefore, the second speed can be a speed within a preset range higher than the first speed, and it can also be determined based on the first operating temperature of the controller. For example, the second speed can be set to be 20 revolutions per second (r / s) greater than the first speed; or the second speed can be associated with the first operating temperature, so that when the first operating temperature is greater than the first temperature threshold, the circulating fan can be controlled to operate at the second speed corresponding to the first operating temperature.

[0034] S103, obtain the second operating temperature of the controller. If the second operating temperature is greater than the first temperature threshold, and the first operating time of the second operating temperature being greater than the first temperature threshold is greater than the first duration threshold, then control the circulating fan to operate at the third speed, where the first speed is less than the second speed and the second speed is less than the third speed.

[0035] In one embodiment, after controlling the circulating fan to run at a second speed, the second operating temperature of the controller is continuously acquired. If it is determined again that the second operating temperature is greater than the first temperature threshold, and the first operating time of the second operating temperature being greater than the first temperature threshold is greater than the preset first duration threshold, it is determined that the current speed of the circulating fan still fails to reduce the operating temperature of the controller, thereby controlling the circulating fan to run at a third speed.

[0036] In this embodiment, the second operating temperature of the controller can be obtained after the circulating fan runs at the second speed for a certain time threshold. By obtaining the second operating temperature of the controller after the circulating fan runs at the second speed for a certain time, the operating temperature of the controller after the circulating fan runs at the second speed can be accurately determined.

[0037] Optionally, the third rotational speed can be a speed within a preset range higher than the second rotational speed. For example, the third rotational speed can be 20 revolutions per second (r / s) greater than the second rotational speed.

[0038] Optionally, in this embodiment, when the second operating temperature is greater than the first temperature threshold, the first operating time of the second operating temperature being greater than the first temperature threshold is greater than the first time duration threshold, and the growth trend of the second operating temperature within the time threshold is greater than the preset trend, the circulating fan is controlled to operate at a third speed. In this case, the first temperature threshold can be set to a temperature value lower than the safe temperature range, and the speed of the circulating fan can be increased in advance when the second operating temperature does not exceed the safe temperature range by observing the growth of the second operating temperature.

[0039] In this embodiment, when the first operating temperature of the controller is detected to be greater than a first temperature threshold during compressor operation, the circulating fan is controlled to run at a second speed. If the second operating temperature of the controller is again detected to be greater than the first temperature threshold, and the first operating time of the second operating temperature being greater than the first temperature threshold is greater than a first duration threshold, the circulating fan is controlled to run at a third speed. When the first operating temperature of the controller is initially detected to be high, the operating temperature of the controller is reduced by increasing the speed of the circulating fan. Subsequently, if the second operating temperature of the controller is still detected to be higher than the first temperature threshold, and the second operating temperature remains higher than the first temperature threshold, the speed of the circulating fan is increased again, controlling the circulating fan to run at the third speed. This method of increasing the speed of the circulating fan cools the controller, avoiding temperature changes in the air conditioner's operating space due to reducing the compressor's operating frequency. While reducing the temperature of the controller, user comfort is ensured.

[0040] Please see Figures 2-5 This is a flowchart illustrating a control method for an air conditioner provided in an embodiment of this application. Figures 2-5 As shown, the method in this application embodiment may include the following steps S201-S205.

[0041] S201, during the process of controlling the operation of the compressor, the circulating fan is controlled to run at a first speed based on the first indoor temperature of the air conditioner's working space, and the first operating temperature of the control device is obtained;

[0042] S202, if the first operating temperature is greater than the first temperature threshold, control the circulating fan to enter the air-raising mode and control the circulating fan to run at the second speed;

[0043] Specifically, please refer to the description of steps S101-S102 in the above-described embodiments, which will not be repeated here.

[0044] S203, obtain the second operating temperature of the controller; if the second operating temperature is less than or equal to the second temperature threshold, and the second operating time of the second operating temperature is less than the second temperature threshold is greater than the first duration threshold, then control the circulating fan to exit the air-raising mode.

[0045] S204, Obtain the second indoor temperature and indoor temperature threshold of the space where the air conditioner operates;

[0046] S205 controls the circulating fan based on a second indoor temperature and an indoor temperature threshold, wherein the second temperature threshold is less than or equal to the first temperature threshold.

[0047] In one embodiment, after controlling the circulating fan to run at a third speed, the second operating temperature of the controller is collected. When the second operating temperature is lower than a second temperature threshold, and the second operating time of the second operating temperature is lower than the second temperature threshold is greater than a first duration threshold, it is determined that the second operating temperature of the controller has been adjusted to a safe temperature range and can be stably maintained within the safe temperature range. Then, the circulating fan is controlled to exit the fan-raising mode. It can be understood that after the circulating fan enters the fan-raising mode, priority should be given to lowering the temperature of the controller to a safe temperature range, thereby controlling the speed of the circulating fan according to the operating temperature of the controller. After the circulating fan exits the fan-raising mode, the operation of the circulating fan can be controlled according to the collected second indoor temperature and indoor temperature threshold.

[0048] For example, after the circulating fan exits the fan speed-up mode, the collected second indoor temperature is compared with the indoor temperature threshold. If the second indoor temperature is lower than the indoor temperature threshold, the speed of the circulating fan can be increased to increase the flow rate of air or refrigerant in the system, thereby potentially improving the efficiency of heat exchange.

[0049] Furthermore, in this embodiment of the application, after controlling the circulating fan to exit the rising air mode, the number of times the circulating fan enters the rising air mode can also be counted. When it is determined that the number of times is greater than the number threshold, the third temperature threshold is updated to the second temperature threshold, wherein the third temperature threshold is less than the second temperature threshold.

[0050] For example, the number of times the circulation fan enters the high-airflow mode can be 4. After the circulation fan exits the high-airflow mode, if the number of times the circulation fan enters the high-airflow mode is counted as 5, it is determined that the number of times the circulation fan enters the high-airflow mode is greater than the number of times the high-airflow mode is entered. Therefore, the condition for the circulation fan to exit the high-airflow mode needs to be updated. The original condition for determining that the circulation fan exits the high-airflow mode (the second temperature threshold (e.g., less than or equal to 50°C)) is updated, and the third temperature threshold (e.g., less than or equal to 40°C) is updated to the second temperature threshold. Thus, when the second operating temperature of the controller is detected to be less than or equal to 40°C, and the second operating time of the second operating temperature is less than or equal to 40°C is greater than the first duration threshold (e.g., 5 minutes), the high-airflow mode is exited.

[0051] In this embodiment, when the second operating temperature of the controller is less than or equal to the second temperature threshold and the second operating time is greater than the first duration threshold, the circulating fan is controlled to exit the fan-up mode. Then, the speed of the circulating fan is controlled according to the collected second indoor temperature and the indoor temperature threshold, thus achieving accurate control of the circulating fan to exit the fan-up mode. After controlling the circulating fan to exit the fan-up mode, the speed of the circulating fan is controlled based on the collected indoor temperature to ensure that the second indoor temperature meets the indoor temperature threshold, improving the user experience. Furthermore, when it is determined that the number of times the circulating fan enters the fan-up mode reaches the number threshold, the second temperature threshold for the circulating fan to exit the fan-up mode is lowered. As a result, the circulating fan can exit the fan-up mode at a lower temperature, avoiding frequent entry and exit of the fan-up mode and ensuring stable operation of the circulating fan.

[0052] Please see Figures 2-5 This is a flowchart illustrating a control method for an air conditioner provided in an embodiment of this application. Figures 2-5 As shown, the method in this application embodiment may include the following steps S301-S303.

[0053] S301, during the process of controlling the operation of the compressor, the circulating fan is controlled to run at a first speed based on the first indoor temperature of the air conditioner's working space, and the first operating temperature of the controller is obtained;

[0054] Specifically, please refer to the description of step S101 in the above embodiment of the specification, which will not be repeated here.

[0055] S302, If the first operating temperature is greater than the first temperature threshold, obtain the operating mode of the air conditioner;

[0056] S303 controls the operation of the circulating fan and compressor based on the first indoor temperature and operating mode.

[0057] In one embodiment, when the first operating temperature of the controller is greater than the first temperature threshold, in addition to controlling the circulating fan, this application can also simultaneously control the speed of the circulating fan and the operating frequency of the compressor.

[0058] It is understandable that most of the heat dissipated by the control device is due to the high frequency of the compressor's operation. Therefore, by reducing the operating frequency of the compressor, the operating temperature of the control device can also be reduced.

[0059] Furthermore, in this embodiment of the application, controlling the operation of the circulating fan and compressor by the first indoor temperature and operating mode includes steps S3031-S3034.

[0060] S3031, if the air conditioner is in heating mode and the first indoor temperature is greater than the first indoor temperature threshold, then control the compressor to reduce its operating frequency and obtain the third operating temperature of the controller. If the third operating temperature is greater than the fourth temperature threshold, then control the speed of the circulating fan to increase.

[0061] In one embodiment, the air conditioner operates in heating mode. When the first indoor temperature is greater than a first indoor temperature threshold, it indicates that the compressor's heating capacity meets the user's needs. At this time, the compressor's operating frequency can be appropriately reduced to lower the operating temperature of the controller. Then, a third operating temperature of the controller is collected. If the third operating temperature is determined to be greater than a fourth temperature threshold, the speed of the circulating fan is increased to lower the controller's temperature. If the third operating temperature is determined to be less than or equal to the fourth temperature threshold, the speed of the circulating fan is not controlled.

[0062] S3032, if the air conditioner is in heating mode and the first indoor temperature is less than or equal to the first indoor temperature threshold, then control the speed of the circulating fan to increase and obtain the third operating temperature of the controller. If the third operating temperature is greater than the fourth temperature threshold, then control the compressor to reduce its operating frequency.

[0063] In one embodiment, when the air conditioner is operating in heating mode, if the first indoor temperature is less than or equal to a first indoor temperature threshold, it means that the compressor's heating capacity is either insufficient or just sufficient to meet the user's needs. If the compressor's operating frequency is reduced at this time, the indoor temperature of the space where the air conditioner operates will be further reduced. Therefore, in this embodiment, the temperature of the controller is first reduced by increasing the speed of the circulating fan; then, the third operating temperature of the controller is collected again. If the third operating temperature is determined to be greater than a fourth temperature threshold, the compressor's operating frequency is reduced; if the third operating temperature is determined to be less than or equal to the fourth temperature threshold, the speed of the circulating fan is not controlled.

[0064] S3033, if the air conditioner is in cooling mode and the first indoor temperature is less than the second indoor temperature threshold, then control the compressor to reduce its operating frequency and obtain the third operating temperature of the controller. If the third operating temperature is greater than the fourth temperature threshold, then control the speed of the circulating fan to increase.

[0065] In one embodiment, the air conditioner operates in cooling mode. When the first indoor temperature is lower than the second indoor temperature threshold, it indicates that the compressor's cooling capacity meets the user's needs. At this time, the compressor's operating frequency can be appropriately reduced to lower the operating temperature of the controller. Then, the third operating temperature of the controller is collected again. If the third operating temperature is determined to be greater than the fourth temperature threshold, the speed of the circulating fan is increased to lower the temperature of the controller. If the third operating temperature is determined to be less than or equal to the fourth temperature threshold, the speed of the circulating fan is not controlled.

[0066] S3034 If the air conditioner is in cooling mode and the indoor temperature is greater than or equal to the second indoor temperature threshold, then control the speed of the circulating fan to increase and obtain the third operating temperature of the controller. If the third operating temperature is greater than the fourth temperature threshold, then control the compressor to reduce its operating frequency.

[0067] In one embodiment, when the air conditioner is operating in cooling mode, if the first indoor temperature is greater than the second indoor temperature threshold, it means that the compressor's cooling capacity is insufficient to meet the user's needs. If the compressor's operating frequency is reduced at this time, the indoor temperature of the space where the air conditioner operates will further increase. Therefore, in this embodiment, the temperature of the controller is first reduced by increasing the speed of the circulating fan; then, the third operating temperature of the controller is collected again. If the third operating temperature is determined to be greater than the fourth temperature threshold, the compressor's operating frequency is reduced; if the third operating temperature is determined to be less than or equal to the fourth temperature threshold, the speed of the circulating fan is not controlled.

[0068] Optionally, in this embodiment of the application, the speed of the circulating fan can be increased according to a preset speed threshold, or the operating frequency of the compressor can be decreased according to a preset frequency threshold, thereby controlling the operation of the circulating fan when the third operating temperature is detected to be greater than the fourth temperature threshold.

[0069] Furthermore, in this embodiment of the application, during the process of controlling the operation of the compressor, a third operating time when the first operating temperature is greater than the first temperature threshold is obtained; if the third operating time is greater than the second operating time threshold, the compressor is controlled to operate at the first frequency; a fourth operating temperature of the controller is obtained, and if the third operating time when the fourth operating temperature is greater than the fifth temperature threshold is greater than the third operating time threshold, the compressor is controlled to operate at the second frequency; a fifth operating temperature of the controller is obtained, and if the fourth operating time when the fifth operating temperature is greater than the sixth temperature threshold is greater than the fourth operating time threshold, the compressor is controlled to stop, wherein the second frequency is less than the first frequency.

[0070] It is understood that, in this embodiment of the application, when the first operating temperature is greater than the first temperature threshold and the first operating time reaches the second time threshold, the current operating frequency (first frequency) of the compressor is maintained first to avoid directly reducing the compressor and affecting the indoor temperature; when the fourth operating temperature of the controller is greater than the fifth temperature threshold and the third operating time is greater than the third time threshold, the compressor is controlled to reduce its current operating frequency and operate at a second frequency lower than the first frequency, thereby reducing the temperature of the controller while minimizing the impact on the indoor temperature; then, when the fifth operating temperature of the controller is greater than the sixth temperature threshold and the fourth operating time is greater than the fourth time threshold, the compressor is controlled to stop, that is, the compressor is directly controlled not to run, to avoid the controller continuing to control the compressor to work under high temperature conditions, which would cause the temperature of the controller to rise continuously and damage the controller; after obtaining the fourth operating temperature and the fifth operating temperature, if it is determined that the fourth operating temperature or the fifth operating temperature does not meet the preset conditions, the compressor is controlled to maintain its current operating frequency.

[0071] Furthermore, in this embodiment, the number of times the circulating fan increases its speed can also be obtained, and the operating frequency of the compressor can be reduced based on the number of times.

[0072] For example, such as Figures 2-5 As shown, when the speed of the internal circulation fan is increased for the first time, the operating frequency of the compressor can be reduced by n (r / s); when the speed of the internal circulation fan is increased for the second time, the operating frequency of the compressor can be reduced by (n+3) (r / s); when the speed of the internal circulation fan is increased for the third time, the operating frequency of the compressor can be reduced by (n+8) (r / s); when the speed of the internal circulation fan is increased for the fourth time, the operating frequency of the compressor can be reduced by (n+15) (r / s); after the speed of the internal circulation fan is increased more than four times, the compressor can be stopped.

[0073] Furthermore, in this embodiment of the application, after the compressor stops, the operating temperature of the controller can be collected in real time. If the operating temperature is determined to be less than or equal to the restart threshold and remains so for a certain period of time (e.g., 3 minutes), the compressor is restarted.

[0074] In this embodiment, when the first operating temperature is greater than a first temperature threshold, it is determined that heat dissipation is needed for the controller. If the air conditioner is in heating mode and the first indoor temperature is greater than the first indoor temperature threshold, the compressor's operating frequency is adjusted first. If the air conditioner is in heating mode and the first indoor temperature is less than the first indoor temperature threshold, the circulating fan speed is adjusted first. This achieves the goal of reducing the operating temperature of the controller while minimizing its impact on the first indoor temperature, thus improving the user experience, even in heating mode. Furthermore, when the air conditioner is in cooling mode, if the first indoor temperature is determined to be less than a second indoor temperature threshold, the compressor's operating frequency is adjusted first. If the first indoor temperature is greater than or equal to the second indoor temperature threshold, the circulating fan speed is adjusted first. This achieves the goal of determining the adjustment order of the compressor and circulating fan based on the obtained first indoor temperature when the air conditioner is in cooling mode and the controller's first operating temperature is greater than the first temperature threshold, thereby reducing the operating temperature of the controller in cooling mode. While reducing the impact on the first indoor temperature, the system improves the user experience. Furthermore, when the third operating time of the first operating temperature exceeding the first temperature threshold is greater than the second time threshold, the compressor is controlled to maintain the first frequency. Then, the fourth operating temperature of the controller is acquired again. When the fourth operating temperature exceeds the fifth temperature threshold and the third operating time is greater than the third time threshold, the compressor is controlled to operate at the second frequency. Finally, when the fifth operating temperature of the controller exceeds the sixth temperature threshold and the fourth operating time is greater than the fourth time threshold, the compressor is controlled to stop. By gradually reducing the compressor's operating frequency, the operating temperature of the controller is lowered, preventing a sharp drop in the compressor's operating frequency from causing a rapid change in indoor temperature within a short period, thus improving user comfort. In this embodiment, the operating frequency of the compressor can also be reduced by increasing the rotation speed of the circulating fan. This combination of lowering the compressor's operating frequency and increasing the fan speed prevents the circulating fan from increasing its speed while the compressor continues to operate at a high frequency, thus avoiding the inability to lower the operating temperature of the controller.

[0102] Please see ​ This document provides a structural schematic diagram of an air conditioner according to an embodiment of this application. ​ As shown, the air conditioner 500 includes a controller 501 and a memory 502. The controller 501 and the memory 502 are electrically connected.

[0103] The control device 501 is the control center of the air conditioner 500 and may include one or more processing cores. The control device 501 connects to various parts of the air conditioner 500 using various interfaces and lines. It executes various functions and processes data of the air conditioner 500 by running or calling computer programs stored in the memory 502 and by calling data stored in the memory 502, thereby providing overall control of the air conditioner 500. Optionally, the control device 501 may be implemented using at least one hardware form of Digital Signal Processing (DSP), Field Programmable Gate Array (FPGA), or Programmable Logic Array (PLA). The control device 501 may integrate one or more of the following: CPU, Graphics Processing Unit (GPU), and modem.

[0115] Get the number of times the circulating fan enters the high-speed mode;

[0116] If the number of occurrences exceeds the threshold, the third temperature threshold is updated to the second temperature threshold, where the third temperature threshold is less than the second temperature threshold.

[0117] Optionally, after obtaining the first operating temperature of the controller, the controller 501 may also perform the following:

[0118] If the first operating temperature is greater than the first temperature threshold, obtain the operating mode of the air conditioner;

[0119] The operation of the circulating fan and compressor is controlled based on the first indoor temperature and operating mode.

[0120] Optionally, when the controller 501 is executing the operation of controlling the circulating fan and compressor based on the first indoor temperature and operating mode, it specifically performs the following:

[0121] If the air conditioner is in heating mode and the first indoor temperature is greater than the first indoor temperature threshold, the compressor operating frequency is reduced to obtain the third operating temperature of the controller. If the third operating temperature is greater than the fourth temperature threshold, the speed of the circulating fan is increased.

[0122] If the air conditioner is in heating mode and the first indoor temperature is less than or equal to the first indoor temperature threshold, the speed of the circulating fan is increased to obtain the third operating temperature of the controller. If the third operating temperature is greater than the fourth temperature threshold, the operating frequency of the compressor is reduced.

[0123] Optionally, when the controller 501 is executing the operation of controlling the circulating fan and compressor based on the first indoor temperature and operating mode, it specifically performs the following:

[0124] If the air conditioner is in cooling mode and the first indoor temperature is less than the second indoor temperature threshold, the compressor's operating frequency is reduced to obtain the third operating temperature of the controller. If the third operating temperature is greater than the fourth temperature threshold, the speed of the circulating fan is increased.

[0125] If the air conditioner is in cooling mode and the indoor temperature is greater than or equal to the second indoor temperature threshold, the speed of the circulating fan is increased to obtain the third operating temperature of the controller. If the third operating temperature is greater than the fourth temperature threshold, the operating frequency of the compressor is reduced.

[0126] Optionally, when the controller 501 executes the control to reduce the operating frequency of the compressor, it specifically performs the following:

[0127] If the first running time exceeds the second time threshold, the compressor is controlled to run at the first frequency;

[0131] The number of times the circulating fan increased its speed was obtained, and the operating frequency of the compressor was reduced based on the number of times.

[0132] In this embodiment, when the first operating temperature of the controller is detected to be greater than a first temperature threshold during compressor operation, the circulating fan is controlled to operate at a second speed. If the second operating temperature of the controller is again detected to be greater than the first temperature threshold, and the first operating time of the second operating temperature being greater than the first temperature threshold is greater than a first duration threshold, the circulating fan is controlled to operate at a third speed. Initially, when the first operating temperature of the controller is detected to be high, the operating temperature of the controller is reduced by increasing the speed of the circulating fan. Subsequently, if the second operating temperature of the controller is still detected to be higher than the first temperature threshold, and the second operating temperature remains higher than the first temperature threshold, the speed of the circulating fan is increased again, controlling the circulating fan to operate at the third speed. This method of increasing the speed of the circulating fan cools the controller, avoiding temperature changes in the air conditioner's operating space due to reducing the compressor's operating frequency. While reducing the temperature of the controller, user comfort is ensured.
