Description

Technical Field

[0001] This application relates to the field of air conditioner technology, such as a method and apparatus for controlling an air conditioner, an air conditioner, and a storage medium. Background Technology

[0002] Currently, with people's pursuit of a comfortable environment, air conditioners have become an indispensable household appliance in daily life. However, because air conditioners operate with a large current, there is a risk of overheating due to excessive current or leakage, which could lead to fires and pose a significant safety hazard. Existing technology typically uses temperature sensors to detect the air conditioner's temperature and shuts it off when the temperature exceeds the set temperature.

[0003] In implementing the embodiments of this disclosure, at least the following problems were found in the related art: In the related art, the air conditioner is usually shut down when its surface temperature is higher than the set temperature to prevent a fire. However, due to excessive current or leakage, the internal temperature of the air conditioner may be higher than its surface temperature. If a fire has already started inside the air conditioner, the fire may not be detected in time because the surface temperature is lower than the set temperature, resulting in poor fire prevention.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

This summary is not a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0006] This disclosure provides a method and apparatus for controlling an air conditioner, an air conditioner, and a storage medium to improve the fire prevention effect during the operation of the air conditioner.

[0007] In some embodiments, a method for controlling an air conditioner includes: detecting the operating states of a plurality of preset target components in the air conditioner, and determining the operating state of each target component; wherein the target component is a component in the air conditioner that poses a fire hazard; the operating state includes an abnormal state or a normal state. If a target component is found to be in an abnormal state, the air conditioner is controlled to issue an alarm.

[0008] In some embodiments, the target components include a compressor, an indoor unit fan, and an outdoor unit fan. The step of detecting the operating states of a plurality of preset target components in the air conditioner and determining the operating state of each target component includes: acquiring a first indoor temperature and a preset target temperature; determining the operating state of the compressor based on the first indoor temperature and the target temperature; detecting the operating state of the indoor unit fan when the compressor is in a normal operating state; and detecting the operating state of the outdoor unit fan when both the indoor unit fan and the compressor are in a normal operating state.

[0009] In some embodiments, determining the operating state of the compressor based on the first indoor temperature and the target temperature includes: determining a reference compressor frequency of the compressor based on the first indoor temperature and the target temperature; determining the actual compressor current of the compressor based on the reference compressor frequency; obtaining the actual compressor frequency corresponding to the actual compressor current; and determining the operating state of the compressor based on the reference compressor frequency and the actual compressor frequency.

[0010] In some embodiments, detecting and determining the operating state of the indoor unit fan includes: setting the fan speed to a preset fan speed and obtaining the actual fan current corresponding to the fan speed. The operating state of the indoor unit fan is then determined based on the fan speed and the actual fan current.

[0011] In some embodiments, detecting and determining the operating state of the outdoor unit fan includes: acquiring a second indoor temperature and the coil temperature of the indoor coil; determining a reference speed of the outdoor unit fan based on the second indoor temperature and the coil temperature; adjusting the speed of the outdoor unit fan based on the reference speed; and then acquiring the actual speed of the adjusted outdoor unit fan. Finally, determining the operating state of the outdoor unit fan based on the reference speed and the actual speed.

[0012] In some embodiments, after determining the operating state of each target component, the method further includes: if all target components are in normal operating condition, acquiring the cabinet temperature of the air conditioner and the smoke concentration in the area where the air conditioner is located. The air conditioner is then controlled to trigger an alarm based on the surface temperature and / or the smoke concentration.

[0013] In some embodiments, the device for controlling an air conditioner includes: a detection module configured to detect the operating states of a plurality of preset target components in the air conditioner and determine the operating state of each target component; wherein the target component is a component in the air conditioner that poses a fire hazard; the operating state includes an abnormal state or a normal state. A first alarm module configured to control the air conditioner to sound an alarm when a target component is in an abnormal state.

[0014] In some embodiments, the apparatus for controlling an air conditioner includes a processor and a memory storing program instructions, the processor being configured to execute the method for controlling the air conditioner described above when the program instructions are executed.

[0015] In some embodiments, the air conditioner includes an air conditioner body. The means for controlling the air conditioner as described above is installed on the air conditioner body.

[0016] In some embodiments, the storage medium stores program instructions that, when executed, perform the method described above for an air conditioner.

[0017] The method, apparatus, air conditioner, and storage medium for controlling an air conditioner provided in this disclosure can achieve the following technical effects: By detecting the working status of multiple preset target components with potential fire hazards in the air conditioner, the working status of each target component is determined. Then, if a target component is in an abnormal state, the air conditioner is controlled to trigger an alarm. In this way, when a target component with a potential fire hazard is in an abnormal working state, the air conditioner is controlled to trigger an alarm, thus predicting and identifying fires from the target component with the potential fire hazard, i.e., the source of fire, so as to promptly control the air conditioner to trigger an alarm. This improves the fire prevention effect during the operation of the air conditioner.

[0033] This disclosure provides a method for controlling an air conditioner. It detects the operating status of multiple preset target components within the air conditioner—components with potential fire hazards—to determine their operational state. Then, if any target component is found to be in an abnormal state, the air conditioner is triggered to sound an alarm. In this way, by controlling the air conditioner to sound an alarm when a target component with a fire hazard is in an abnormal operating state, fire can be predicted and identified from the perspective of the target component, i.e., the source of fire, allowing for timely alarm activation. This improves the fire prevention effect during the operation of the air conditioner.

[0034] Combination Figure 1 As shown in the embodiments of this disclosure, a method for controlling an air conditioner is provided, comprising:

[0035] Step S101: The air conditioner detects the operating status of multiple preset target components within the air conditioner to determine the operating status of each target component. The target components are those within the air conditioner that pose a fire hazard. Operating status includes abnormal and normal states.

[0036] Step S102: If a target component is in an abnormal state, the air conditioner will be controlled to issue an alarm.

[0037] The method for controlling an air conditioner provided in this disclosure detects the operating status of multiple pre-set target components within the air conditioner that pose a fire hazard, determines the operating status of each target component, and then controls the air conditioner to issue an alarm if any target component is in an abnormal state. In this way, by controlling the air conditioner to issue an alarm when a target component posing a fire hazard is in an abnormal operating state, fires are predicted and identified from the target component, i.e., the source of the fire, so as to promptly control the air conditioner to issue an alarm. This improves the fire prevention effect during the operation of the air conditioner.

[0038] Furthermore, the target components include the compressor, indoor unit fan, and outdoor unit fan. If any target component is in an abnormal state, the air conditioner will be controlled to issue an alarm, including: an alarm will be issued if the compressor is in an abnormal state; or, an alarm will be issued if the indoor unit fan is in an abnormal state; or, an alarm will be issued if the compressor is in an abnormal state (e.g., the outdoor unit fan).

[0039] Furthermore, controlling the air conditioner to trigger an alarm includes: controlling the air conditioner to shut down. A preset fire alarm message is sent to a preset terminal device. This terminal device includes a mobile phone, tablet, or computer. In some embodiments, the preset terminal device is the user terminal of the person in charge of the area where the air conditioner is located. For example, the user terminals of each user in a household, the homeowner's user terminal, or the property manager's user terminal. This allows for timely transmission of information about abnormal operating conditions of the air conditioner's target components to the person in charge of the area. This facilitates timely repair of the target components, ensuring their normal operation and reducing the likelihood of fires caused by abnormal operating conditions of the target components.

[0040] Optionally, the operating status of multiple preset target components in the air conditioner is detected to determine the operating status of each target component, including: acquiring a first indoor temperature and a preset target temperature; determining the operating status of the compressor based on the first indoor temperature and the target temperature; detecting and determining the operating status of the indoor unit fan when the compressor is in normal operation; and detecting and determining the operating status of the outdoor unit fan when both the indoor unit fan and the compressor are in normal operation. This allows for the sequential detection of the operating status of the compressor, indoor unit fan, and outdoor unit fan, enabling the air conditioner to alarm if any of these components malfunctions. This ensures the normal operation of the air conditioner's compressor, indoor unit fan, and outdoor unit fan, reducing the risk of fire.

[0041] Furthermore, the first indoor temperature is obtained as follows: upon receiving a power-on command, the air conditioner uses a first temperature sensor to collect the indoor temperature data. The power-on command is a command sent by the user via a remote control device. The remote control device includes a remote controller or a user terminal with an application program corresponding to the air conditioner installed.

[0042] Optionally, determining the compressor's operating state based on the first indoor temperature and the target temperature includes: determining a reference compressor frequency based on the first indoor temperature and the target temperature; determining the actual compressor current based on the reference compressor frequency; obtaining the actual compressor frequency corresponding to the actual compressor current; and determining the compressor's operating state based on the reference compressor frequency and the actual compressor frequency. Thus, by determining the compressor's reference compressor frequency based on the first indoor temperature and the target temperature, determining the actual compressor current based on the reference compressor frequency, and then obtaining the actual compressor frequency corresponding to the actual compressor current, the compressor's operating state can be determined based on the reference compressor frequency and the actual compressor frequency. This facilitates controlling the air conditioner's alarm in case of an abnormal compressor operating state, thereby ensuring the compressor's normal operation and reducing the risk of fire.

[0043] Furthermore, determining the reference compressor frequency based on the first indoor temperature and the target temperature includes: acquiring the air conditioner's operating mode; acquiring the temperature difference between the first indoor temperature and the target temperature; and determining the reference compressor frequency based on the temperature difference and the operating mode. The air conditioner's operating mode includes either cooling or heating mode. This allows the reference compressor frequency to be obtained based on the temperature difference and the operating mode, facilitating the determination of the actual compressor current, and then obtaining the actual compressor frequency corresponding to the actual compressor current. This allows for the determination of the compressor's operating state based on the reference compressor frequency and the actual compressor frequency, enabling the air conditioner to alarm in case of abnormal compressor operation. This ensures the normal operation of the compressor and reduces the risk of fire. Simultaneously, since the reference compressor frequency is determined based on the temperature difference between the first indoor temperature and the target temperature, the actual compressor frequency is approximately equal to the reference compressor frequency when the compressor is operating normally, better matching the indoor temperature and facilitating faster temperature adjustment, thus improving the user experience.

[0044] Furthermore, the method of obtaining the air conditioner's operating mode includes: determining heating mode as the air conditioner's operating mode when the first indoor temperature is less than or equal to the target temperature; and / or determining cooling mode as the air conditioner's operating mode when the first indoor temperature is greater than the target temperature.

[0045] Furthermore, determining the reference compressor frequency based on the temperature difference and operating mode includes: performing a lookup operation on the temperature difference and operating mode in a preset compressor frequency database to obtain the reference compressor frequency corresponding to both the temperature difference and the operating mode. The preset compressor frequency database stores the correspondence between the temperature difference, operating mode, and reference compressor frequency.

[0046] Furthermore, determining the actual compressor current based on the reference compressor frequency includes: performing a lookup operation on the reference compressor frequency in a preset compressor current database to obtain the actual compressor current corresponding to the reference compressor frequency. The preset compressor current database stores the correspondence between the reference compressor frequency and the actual compressor current.

[0047] Furthermore, obtaining the actual compressor frequency corresponding to the actual compressor current includes: adjusting the compressor current to the actual compressor current. Then, obtaining the actual compressor frequency.

[0048] Furthermore, determining the compressor's operating state based on the reference compressor frequency and the actual compressor frequency includes: if an actual compressor frequency is obtained, acquiring the frequency difference between the reference compressor frequency and the actual compressor frequency. If the frequency difference is less than or equal to a preset deviation threshold, the compressor is determined to be in a normal operating state. And / or, if the frequency difference is greater than a preset first deviation threshold, the compressor is determined to be in an abnormal operating state.

[0049] In some embodiments, after determining the actual compressor current i2 based on the reference compressor frequency, the actual compressor frequency corresponding to the actual compressor current is obtained as 0 Hz. It is evident that the compressor has stopped. This abnormal state needs to be identified as the compressor's operating state.

[0050] Furthermore, determining the compressor's operating state based on the reference compressor frequency and the actual compressor frequency includes: when multiple actual compressor frequencies are obtained, acquiring the frequency difference between the reference compressor frequency and each actual compressor frequency. If all frequency differences are less than or equal to a preset deviation threshold, the normal state is determined as the compressor's operating state. And / or, if there is a frequency difference greater than a preset first deviation threshold, an abnormal state is determined as the compressor's operating state.

[0051] In some embodiments, after determining the actual compressor current i1 based on the reference compressor frequency, multiple actual compressor frequencies (f1, f1, f1, f2, f2) corresponding to the actual compressor current are obtained. The frequency difference between f1 and the reference compressor frequency is equal to 0. The frequency difference between f2 and the reference compressor frequency is greater than a preset first deviation threshold. Therefore, the compressor frequency has jumped from f1 to f2, and the frequency difference between f2 and the reference compressor frequency is greater than the preset first deviation threshold; that is, the compressor frequency has hopped. This abnormal state is determined as the compressor's operating state.

[0052] Optionally, the operating status of the indoor unit fan can be detected and determined, including: setting the fan speed to a preset speed and obtaining the actual fan current corresponding to that speed. The operating status of the indoor unit fan is determined based on the fan speed and actual fan current. This allows for the determination of whether the indoor unit fan is operating normally or abnormally, enabling the air conditioner to alarm in case of an abnormal operating status. This ensures the normal operation of the indoor unit fan and reduces the risk of fire.

[0053] Furthermore, the preset fan speed includes one or more of the following: preset silent speed, preset low speed, preset medium speed, preset high speed, and preset strong speed. The silent speed is lower than the low speed. The low speed is lower than the medium speed. The medium speed is lower than the high speed. The high speed is lower than the strong speed. Setting the indoor unit fan speed to the preset fan speed and obtaining the corresponding actual fan current includes: when there are multiple preset fan speeds, setting the indoor unit fan speed to each preset fan speed according to a preset number of cycles and a preset order, and obtaining the corresponding actual fan current. And / or, when there is only one preset fan speed, setting the indoor unit fan speed to the preset fan speed multiple times, and obtaining the corresponding actual fan current. In some embodiments, the number of cycles is one or two. The preset order is from low to high speed or from high to low speed. In this way, the operating status of the indoor unit fan can be determined based on different fan speeds and their corresponding actual fan currents, thus improving the accuracy of detecting the operating status of the indoor unit fan.

[0054] In some embodiments, the preset fan speeds include a preset silent speed, a preset medium speed, and a preset high speed. The air conditioner sets the indoor unit fan speed to silent speed and obtains the actual fan current corresponding to silent speed. Then, the air conditioner sets the indoor unit fan speed to medium speed and obtains the actual fan current corresponding to medium speed. Finally, the air conditioner sets the indoor unit fan speed to high speed and obtains the actual fan current corresponding to high speed. The operating state of the indoor unit fan is then determined based on each fan speed and each actual fan current.

[0055] Furthermore, the operating state of the indoor unit fan is determined based on the fan speed and actual fan current, including: obtaining the reference fan current corresponding to the fan speed; and determining the operating state of the indoor unit fan based on the reference fan current and the actual fan current.

[0056] Furthermore, obtaining the reference fan current corresponding to the fan speed includes: performing a lookup operation on the fan speed in a preset fan current database to obtain the reference fan current corresponding to the fan speed. The preset fan current database stores the correspondence between fan speeds and reference fan currents. The reference fan current corresponding to the fan speed includes: the supply air reference fan current corresponding to the supply air speed, the medium wind reference fan current corresponding to the medium wind speed, and the strong wind reference fan current corresponding to the strong wind speed.

[0057] Furthermore, determining the operating state of the indoor unit fan based on the reference fan current and the actual fan current includes: obtaining a first current difference between the actual fan current corresponding to the fan speed and the reference fan current corresponding to the same fan speed, given one cycle. If the first current difference is greater than a preset second deviation threshold, an abnormal state is determined to be the operating state of the indoor unit fan. And / or, if the first current difference is less than or equal to the preset second deviation threshold, a normal state is determined to be the operating state of the indoor unit fan.

[0058] Furthermore, the operating state of the indoor unit fan is determined based on the reference fan current and the actual fan current, including: obtaining the average value of the actual fan current corresponding to the same fan speed after two cycles, and obtaining the average fan current corresponding to each fan speed. A second current difference is obtained between the average fan current corresponding to each fan speed and the reference fan current corresponding to that fan speed. If any second current difference is greater than a preset second deviation threshold, an abnormal state is determined as the operating state of the indoor unit fan. And / or, if all second current differences are less than or equal to the preset second deviation threshold, a normal state is determined as the operating state of the indoor unit fan.

[0059] Furthermore, after determining the normal state as the working state of the indoor unit fan, it also includes: controlling the indoor unit fan to operate at the default fan speed or the fan speed set by the user.

[0060] Optionally, the operating status of the outdoor unit fan is detected and determined, including: acquiring the second indoor temperature and the coil temperature of the indoor coil; determining a reference speed for the outdoor unit fan based on the second indoor temperature and the coil temperature; adjusting the outdoor unit fan speed according to the reference speed, and then acquiring the actual speed of the adjusted outdoor unit fan; and finally determining the operating status of the outdoor unit fan based on the reference speed and the actual speed. In this way, by determining the reference speed of the outdoor unit fan based on the second indoor temperature and the coil temperature, adjusting the outdoor unit fan speed according to the reference speed, acquiring the actual speed of the adjusted outdoor unit fan, and then determining the operating status of the outdoor unit fan based on the reference speed and the actual speed, the operating status of the outdoor unit fan is detected. This allows for the control of the air conditioner alarm in the event of an abnormal operating status of the outdoor unit fan, thereby ensuring the normal operation of the outdoor unit fan and reducing the occurrence of fires.

[0061] Furthermore, the second indoor temperature is obtained by the following method: when the indoor unit of the air conditioner is in a stable temperature control state, the indoor temperature is collected using the first temperature sensor to obtain the second indoor temperature.

[0062] Furthermore, the indoor unit of the air conditioner is determined to be in a stable temperature control state by the following method: when the indoor temperature is equal to the target temperature, the indoor unit of the air conditioner is determined to be in a stable temperature control state.

[0063] Furthermore, determining the reference speed of the outdoor unit fan based on the second indoor temperature and the coil temperature includes: obtaining the indoor unit heat exchange rate of the air conditioner based on the second indoor temperature and the coil temperature; determining the indoor unit heat exchange rate as the outdoor unit heat exchange rate of the air conditioner; and determining the reference speed of the outdoor unit fan based on the outdoor unit heat exchange rate. In this way, since the air conditioner's heat exchange is balanced when the indoor unit is in a stable temperature control state, that is, the indoor unit heat exchange rate is equal to the outdoor unit heat exchange rate. Therefore, by obtaining the indoor unit heat exchange rate based on the second indoor temperature and the coil temperature, and determining the indoor unit heat exchange rate as the outdoor unit heat exchange rate of the air conditioner, the outdoor unit heat exchange rate of the air conditioner can be obtained.

[0064] Furthermore, the heat exchange rate of the indoor unit of the air conditioner is obtained based on the second indoor temperature and the coil temperature, including: calculating the heat exchange rate of the indoor unit of the air conditioner by calculating n1 = |Tt| / T. Where n1 is the heat exchange rate of the indoor unit of the air conditioner, T is the second indoor temperature, and t is the coil temperature.

[0065] Furthermore, the reference speed of the outdoor unit fan is determined based on the outdoor unit's heat exchange rate, including: when the outdoor unit's heat exchange rate is greater than or equal to a preset reference threshold, a preset high fan speed is determined as the reference speed of the outdoor unit fan; and / or, when the outdoor unit's heat exchange rate is less than a preset reference threshold, a preset low fan speed is determined as the reference speed of the outdoor unit fan. The preset reference threshold is 1. Thus, the reference speed of the outdoor unit fan is determined by the relationship between the outdoor unit's heat exchange rate and the reference threshold. This allows for adjusting the outdoor unit fan speed according to the reference speed to obtain the actual speed of the outdoor unit fan, and for determining the operating state of the outdoor unit fan based on the reference speed and the actual speed.

[0066] Furthermore, the speed of the outdoor unit fan is adjusted according to the reference speed, including adjusting the speed of the outdoor unit fan to the reference speed.

[0067] Furthermore, the operating state of the outdoor unit fan is determined based on the reference speed and the actual speed, including: when the reference speed and the actual speed are the same, the normal state is determined as the operating state of the outdoor unit fan; and / or, when the reference speed and the actual speed are different, the abnormal state is determined as the operating state of the outdoor unit fan.

[0068] Combination Figure 2 As shown in the embodiments of this disclosure, a method for controlling an air conditioner is provided, comprising:

[0069] Step S201: The air conditioner acquires the first indoor temperature and the preset target temperature.

[0070] In step S202, the air conditioner determines the reference compressor frequency of the compressor based on the first indoor temperature and the target temperature.

[0071] Step S203: The air conditioner determines the actual compressor current of the compressor based on the reference compressor frequency.

[0072] Step S204: The air conditioner obtains the actual compressor frequency corresponding to the actual compressor current.

[0073] In step S205, the air conditioner determines the operating state of the compressor based on the reference compressor frequency and the actual compressor frequency. The operating state includes either an abnormal state or a normal state.

[0074] Step S206: When the compressor is in normal operation, the air conditioner sets the indoor unit fan speed to a preset fan speed and obtains the actual fan current corresponding to the fan speed.

[0075] Step S207: The air conditioner determines the operating state of the indoor unit fan based on the fan speed and the actual fan current.

[0076] Step S208: With the indoor unit fan and compressor both in normal working order, the air conditioner acquires the second indoor temperature and the coil temperature of the indoor coil.

[0077] Step S209: The air conditioner determines the reference speed of the outdoor unit fan based on the second indoor temperature and the coil temperature.

[0078] In step S210, the air conditioner adjusts the speed of the outdoor unit fan according to the reference speed, and then obtains the actual speed of the adjusted outdoor unit fan.

[0079] Step S211: The air conditioner determines the operating state of the outdoor unit fan based on the reference speed and the actual speed.

[0080] Step S212: If a target component is found to be in an abnormal state, the air conditioner will trigger an alarm. The target component is a part of the air conditioner that poses a fire hazard.

[0081] The method for controlling an air conditioner provided in this disclosure determines the actual compressor current by determining the reference compressor frequency based on a first indoor temperature and a preset target temperature. The operating state of the compressor is then determined based on the actual compressor frequency corresponding to the actual compressor current and the reference compressor frequency. When the compressor is in normal operation, the actual fan current corresponding to the indoor unit fan speed is obtained, and the operating state of the indoor unit fan is determined based on the fan speed and the actual fan current. When both the indoor unit fan and the compressor are in normal operation, the speed of the outdoor unit fan is adjusted based on a second indoor temperature and the coil temperature, and the operating state of the outdoor unit fan is determined based on the adjustment. Then, if any of the compressor, indoor unit fan, or outdoor unit fan is in an abnormal state, the air conditioner is controlled to issue an alarm. This allows for sequential detection of the operating states of the compressor, indoor unit fan, and outdoor unit fan, enabling timely alarms in case of abnormal conditions. This reduces the risk of fires caused by compressor, indoor unit fan, or outdoor unit fan malfunctions and improves the fire prevention effect during air conditioner operation.

[0082] Optionally, after determining the operating status of each target component, the method further includes: acquiring the air conditioner's casing temperature and the smoke concentration in the area where the air conditioner is located, assuming all target components are in normal operating conditions. The air conditioner is then controlled to trigger an alarm based on the surface temperature and / or smoke concentration. This allows the air conditioner to trigger an alarm based on the air conditioner's casing temperature and the smoke concentration in the area where the air conditioner is located, even when all target components are in normal operating conditions.

[0083] Furthermore, the air conditioner's casing temperature is obtained using the following method: a second temperature sensor is used to collect the temperature data of the air conditioner's casing. The second sensor is located at the capacitor on the air conditioner's circuit board.

[0084] Furthermore, the smoke concentration in the area where the air conditioner is located is obtained using the following method: a smoke sensor is used to obtain the smoke concentration in the area where the air conditioner is located. The smoke sensor is located above the air conditioner.

[0085] In some embodiments, the air conditioner is a wall-mounted unit, suspended on the wall, and the smoke sensor is installed on the ceiling, directly above the wall-mounted unit. This way, in the event of a fire in the air conditioner, the smoke generated by the fire rises. The smoke sensor located directly above the wall-mounted unit can detect the smoke immediately.

[0086] Furthermore, the air conditioner is controlled to trigger an alarm based on surface temperature and / or smoke concentration, including: triggering an alarm when the surface temperature exceeds a preset temperature threshold; and / or triggering an alarm when the smoke concentration exceeds a preset concentration threshold.

[0087] Furthermore, after obtaining the air conditioner's casing temperature and the smoke concentration in the area where the air conditioner is located, the system also includes: controlling the air conditioner to issue an alarm when the surface temperature exceeds a preset temperature threshold and the smoke concentration exceeds a preset concentration threshold.

[0088] Combination Figure 3 As shown in the embodiments of this disclosure, a method for controlling an air conditioner is provided, comprising:

[0089] Step S301: The air conditioner acquires the first indoor temperature and the preset target temperature. Then, step S302 is executed.

[0090] In step S302, the air conditioner determines the operating state of the compressor based on the first indoor temperature and the target temperature. Then, step S303 is executed.

[0091] Step S303: The air conditioner determines whether the compressor is in a normal operating state. If yes, proceed to step S304. If no, proceed to step S310.

[0092] Step S304: The air conditioner detects the operating status of the indoor unit fan and determines its operating status. Then, step S305 is executed.

[0093] Step S305: The air conditioner determines whether the indoor unit fan is in a normal operating state. If yes, proceed to step S306. If no, proceed to step S310.

[0094] Step S306: The air conditioner detects the operating status of the outdoor unit fan to determine its operating status. Then, step S307 is executed.

[0095] Step S307: The air conditioner determines whether the outdoor unit fan is in a normal operating state. If yes, proceed to step S308. If no, proceed to step S310.

[0096] Step S308: The air conditioner acquires the unit temperature and the smoke concentration in the area where the air conditioner is located. Then, step S309 is executed.

[0097] Step S309: The air conditioner controls the air conditioner to trigger an alarm based on the surface temperature and / or smoke concentration.

[0098] Step S310: The air conditioner controls the air conditioner to sound an alarm.

[0099] The method for controlling an air conditioner provided in this disclosure sequentially detects the operating status of the compressor, indoor unit fan, and outdoor unit fan. It promptly issues alarms when the compressor, indoor unit fan, or outdoor unit fan is in an abnormal state, or when the air conditioner's casing temperature or the smoke concentration in the area where the air conditioner is located is abnormal. This improves the fire prevention effect during the air conditioner's operation. Furthermore, because the air conditioner will issue an alarm when the compressor, indoor unit fan, or outdoor unit fan is in an abnormal state, it ensures that the compressor, indoor unit fan, and outdoor unit fan are all in normal working order during normal operation, thus improving the user experience.
