Description

Technical Field

[0001] This application relates to the field of air conditioner technology, and in particular to air conditioner control methods, air conditioners, and storage media. Background Technology

[0002] Currently, air conditioners with "smart eye" functionality primarily achieve energy savings by automatically adjusting the compressor's maximum operating frequency based on whether someone is in the room. However, in environments with limited space or low cooling load, the air conditioner easily reaches its load requirement and proactively reduces its frequency to a lower level. Further restricting its maximum operating frequency contradicts this proactive frequency-reduction mechanism, preventing the air conditioner from continuing to reduce its frequency most of the time, thus impacting energy efficiency. Summary of the Invention

[0003] The main purpose of this application is to provide a control method for an air conditioner, an air conditioner, and a storage medium, with the aim of improving the energy-saving effect of the air conditioner.

[0004] To achieve the above objectives, this application proposes a control method for an air conditioner, the method comprising:

[0005] If the room where the air conditioner is located is found to be unoccupied, the current set temperature of the air conditioner will be adjusted to reduce the temperature difference between the room temperature and the current set temperature.

[0006] The air conditioner is controlled based on the adjusted set temperature.

[0007] If the indoor space where the air conditioner is located is detected to be unoccupied for a preset number of consecutive times, the air conditioner will be controlled to operate according to the set operating parameters.

[0008] In one embodiment, if it is detected that no one is in the indoor space where the air conditioner is located, adjusting the current set temperature of the air conditioner includes:

[0009] When the air conditioner is in heating mode, if it is detected that no one is in the room where the air conditioner is located, the current set temperature of the air conditioner will be lowered.

[0010] Alternatively, if the air conditioner is in cooling mode and the room where the air conditioner is located is detected to be unoccupied, the current set temperature of the air conditioner can be increased.

[0011] In one embodiment, when the air conditioner is in heating mode, if it is detected that no one is in the room where the air conditioner is located, lowering the current set temperature of the air conditioner includes:

[0012] When the air conditioner is in heating mode, if it is detected that there is no one in the room where the air conditioner is located, the current indoor temperature and the current set temperature of the room where the air conditioner is located are obtained.

[0013] Determine the first temperature difference between the indoor temperature and the currently set temperature;

[0014] The first temperature difference is reduced according to a first ratio to obtain a reduced first temperature difference;

[0015] Based on the reduced first temperature difference and the current indoor temperature, the set temperature value after adjustment in heating mode is obtained.

[0016] In one embodiment, when the air conditioner is in cooling mode, if it is detected that someone is in the room where the air conditioner is located, increasing the current set temperature of the air conditioner includes:

[0017] When the air conditioner is in cooling mode, if it is detected that there is no one in the room where the air conditioner is located, the current indoor temperature and the current set temperature of the room where the air conditioner is located are obtained.

[0018] Determine the second temperature difference between the indoor temperature and the currently set temperature;

[0019] The second temperature difference is reduced according to the second ratio to obtain the reduced second temperature difference;

[0020] Based on the reduced second temperature difference and the current indoor temperature, the set temperature value after adjustment in cooling mode is obtained.

[0021] In one embodiment, if it is detected that no one is in the indoor space where the air conditioner is located, adjusting the current set temperature of the air conditioner includes:

[0022] The system checks at preset intervals whether the indoor space where the air conditioner is located is unoccupied. If so, it adjusts the current set temperature of the air conditioner.

[0023] In one embodiment, if the indoor space where the air conditioner is located is detected to be unoccupied a preset number of times, controlling the air conditioner to operate according to the set operating parameters includes:

[0024] If the room where the air conditioner is located is detected to be unoccupied for a preset number of consecutive times, the compressor of the air conditioner will be controlled to run at the minimum operating frequency or stop.

[0025] In one embodiment, the air conditioner control method further includes:

[0026] If someone is detected in the room where the air conditioner is located, the air conditioner will be controlled to operate based on its actual set temperature.

[0027] The actual set temperature is either the default temperature of the air conditioner or the temperature set when the air conditioner is turned on.

[0028] In one embodiment, if it is detected that no one is in the indoor space where the air conditioner is located, adjusting the current set temperature of the air conditioner includes:

[0029] If the indoor space where the air conditioner is located is detected to be unoccupied, obtain the indoor temperature of the indoor space where the air conditioner is located and the current set temperature of the air conditioner;

[0030] Determine the third temperature difference between the indoor temperature and the currently set temperature;

[0031] If the third temperature difference is greater than the preset temperature difference, the current set temperature of the air conditioner will be adjusted.

[0032] In addition, to achieve the above objectives, this application also proposes an air conditioner, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, the computer program being configured to implement the steps of the control method for the air conditioner as described above.

[0033] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the steps of the air conditioner control method described above.

[0034] The present application proposes one or more technical solutions that, when an unoccupied indoor space is detected, adjust the air conditioner's current set temperature to reduce the temperature difference between the indoor temperature and the set temperature. This helps reduce the air conditioner's energy consumption because when the temperature difference is small, the air conditioner does not need to operate at high power to maintain the indoor temperature. Furthermore, adjusting the set temperature can further reduce the air conditioner's operating frequency, complementing the active frequency reduction mechanism and achieving more efficient energy saving. This solution does not directly limit the air conditioner's maximum operating frequency but indirectly affects its operating state by adjusting the set temperature. This avoids conflict with the air conditioner's active frequency reduction mechanism, enabling the air conditioner to maintain stable operation in various environments. Moreover, by continuously detecting unoccupied indoor spaces a preset number of times, the user's usage habits and needs can be more accurately determined. Based on this, the air conditioner is controlled to operate according to the set parameters, ensuring both energy saving and meeting the user's comfort requirements. Attached Figure Description

[0041] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0042] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0043] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0044] With the advancement of technology, smart home products are becoming increasingly popular, among which air conditioners with "smart eye" functionality have become a hot product in the market. These air conditioners use built-in cameras or sensors to detect whether anyone is in the room in real time and automatically adjust the compressor's maximum operating frequency accordingly to achieve energy savings. When no one is detected in the room, the air conditioner automatically reduces the compressor's operating frequency to reduce energy consumption; when someone is detected, it increases the compressor's operating frequency to meet the user's cooling or heating needs. However, in practical applications, the energy-saving effect of this "smart eye" function air conditioner faces challenges in environments with small installation spaces or low cooling loads. Due to the characteristics of these environments, the air conditioner easily reaches its load demand and actively reduces its frequency to a lower level. If, in this case, the maximum operating frequency of the air conditioner is further limited using the "smart eye" function in the traditional way, it will contradict the air conditioner's active frequency reduction mechanism. Specifically, when the air conditioner has already actively reduced its frequency to near its minimum stable operating frequency, further limiting the maximum operating frequency will prevent the air conditioner from continuing to reduce its frequency for most of the time, thus limiting its energy-saving potential.

[0045] To alleviate the above problems, this application proposes a control method for an air conditioner. The main technical solution includes: if it is detected that no one is in the indoor space where the air conditioner is located, the current set temperature of the air conditioner is adjusted to reduce the temperature difference between the indoor temperature of the indoor space where the air conditioner is located and the current set temperature; based on the adjusted set temperature, the air conditioner is controlled to operate; if no one is detected in the indoor space where the air conditioner is located for a preset number of consecutive times, the air conditioner is controlled to operate according to the set operating parameters.

[0046] Compared to related technologies, this application, when detecting that the indoor space where the air conditioner is located is unoccupied, adjusts the current set temperature of the air conditioner to reduce the temperature difference between the indoor temperature and the set temperature. This helps reduce the energy consumption of the air conditioner because when the temperature difference is small, the air conditioner does not need to operate at high power to maintain the indoor temperature. Furthermore, by adjusting the set temperature, the operating frequency of the air conditioner can be further reduced, complementing the active frequency reduction mechanism and achieving more efficient energy saving. This solution does not directly limit the maximum operating frequency of the air conditioner, but indirectly affects its operating state by adjusting the set temperature. This avoids conflict with the active frequency reduction mechanism, allowing the air conditioner to maintain stable operation in various environments. Moreover, by continuously detecting that the indoor space is unoccupied a preset number of times, the user's usage habits and needs can be more accurately determined. Based on this, the air conditioner is controlled to operate according to the set operating parameters, ensuring both energy saving and meeting the user's comfort requirements.

[0047] The following embodiments are applicable to various air conditioners. This application does not limit the type of air conditioner, which may include, but is not limited to: wall-mounted air conditioners, floor-standing air conditioners, inverter air conditioners, cabinet air conditioners, ceiling-mounted air conditioners, window air conditioners, portable air conditioners, and built-in air conditioners. Each air conditioner contains multiple components, primarily including a compressor, condenser, evaporator, four-way valve, throttling device, indoor fan, and outdoor fan.

[0048] In the following embodiments, the air conditioner can be installed in a variety of environments, including but not limited to: office areas, conference rooms, family bedrooms, living rooms, factory areas, etc. This application does not limit the specific applicable environment of the air conditioner.

[0049] Accordingly, this application provides a control method for an air conditioner, referring to... Figure 1 , Figure 1 This is a flowchart illustrating some embodiments of the air conditioner control method of this application. In some embodiments of this application, the air conditioner control method includes steps S10 to S30:

[0050] Step S10: If it is detected that no one is in the indoor space where the air conditioner is located, adjust the current set temperature of the air conditioner to reduce the temperature difference between the indoor temperature and the current set temperature of the indoor space where the air conditioner is located.

[0051] It should be noted that the current set temperature refers to the current cooling, heating, or dehumidifying temperature set by the air conditioner. This current set temperature can be the initial temperature set when the air conditioner is started, or the default temperature set when the air conditioner is started; it can also be the set temperature reached automatically during air conditioner operation based on whether there are people or not in the room. This current set temperature changes in real time and is not a fixed setting.

[0052] It should be noted that indoor temperature refers to the ambient temperature of the indoor space where the air conditioner is located. This temperature can be obtained in real-time or through timed sampling using sensors or other methods. As the set temperature of the air conditioner changes, its operating parameters also change, and consequently, the indoor temperature of the space where the air conditioner is located also changes.

[0053] In one feasible implementation, the presence of people in the indoor space where the air conditioner is located can be detected by any combination of one or more of the following methods:

[0054] Infrared sensors, either mounted on the air conditioner or installed within the room where it is located, can detect whether someone is in the room. Specifically, the infrared sensors detect the infrared radiation emitted by the human body to determine if someone is present. When someone enters the detection area, the infrared sensor receives the infrared radiation emitted by the human body, triggering a signal to notify the air conditioner that someone is in the room. This method has the advantages of fast response and high detection accuracy.

[0055] By installing cameras on or within the air conditioner's location, images of the room are captured. Image recognition algorithms are then used to analyze these images to determine the presence of people in the room. The cameras are freely rotating, allowing them to capture images of the entire room. Analysis of the surveillance footage reveals the presence of people and tracks their movements, making this method more flexible and enabling accurate detection of the number of people in a room.

[0056] Human body sensors, installed on the air conditioner or within the room where it is located, detect whether someone is in the room. Specifically, the sensors determine the presence of someone by detecting changes in microwaves or electric fields within the room. When someone enters the detection area, their body interferes with the distribution of microwaves or electric fields, triggering the sensor to emit a signal. This method has the advantages of a wide detection range and is unaffected by light.

[0057] Alternatively, weight sensors installed on the floor or near seats within the room where the air conditioner is located can detect whether someone is in the room. The presence of someone is determined by detecting changes in pressure exerted by a person on the device. When someone sits on a seat or stands on the floor, the weight sensor detects the pressure change and sends a signal.

[0058] It also employs AI smart eye technology to detect whether there are people in the indoor space where the air conditioner is located. Specifically, AI smart eye technology combines advanced technologies such as cameras, image recognition, and artificial intelligence to detect the location of people in real time, determine their temperature, and adjust the temperature and airflow accordingly. This technology can not only detect whether there are people in the indoor space, but also make intelligent adjustments based on people's needs and preferences, and can detect the location of people in real time and adjust the airflow direction and temperature.

[0059] In another feasible implementation, the system checks whether there are people in the indoor space where the air conditioner is located at preset intervals. Once it is detected that no one is in the indoor space where the air conditioner is located, the air conditioner is adjusted. By adjusting the current set temperature of the air conditioner, the temperature difference between the indoor temperature and the current set temperature is reduced, so that the current set temperature gradually approaches the indoor temperature, thereby achieving the purpose of energy saving.

[0060] Based on the above, in another feasible implementation, if the indoor space where the air conditioner is located is detected to be unoccupied through the above method, the air conditioner automatically adjusts its current set temperature. Adjusting the current set temperature includes either increasing or decreasing it. Specifically, this can be achieved by: determining the adjustment direction of the current set temperature based on the air conditioner's current operating mode, and adjusting the current set temperature based on the determined adjustment direction; or, determining the adjustment step size of the current set temperature based on the air conditioner's current operating mode, and adjusting the current set temperature based on the determined adjustment step size; or, determining both the adjustment direction and adjustment step size based on the air conditioner's current operating mode, and adjusting the current set temperature based on the determined adjustment direction and adjustment step size. Through these methods, intelligent and flexible adjustment of the air conditioner's current set temperature is achieved when the indoor space where the air conditioner is located is realized, making the adjustment method of the air conditioner's current set temperature more intelligent and flexible. The aforementioned operating mode can be cooling mode, heating mode, dehumidification mode, etc.

[0061] In another feasible implementation, the current indoor temperature of the room where the air conditioner is located and the reduction ratio of the temperature difference between the current temperature and the current set temperature can also be obtained. Based on this reduction ratio, the temperature difference is reduced, thereby determining the adjustment amount of the current set temperature. The reduction ratio is different for different operating modes of the air conditioner. For example, in heating mode, the reduction ratio may be a first ratio, and in cooling mode, the reduction ratio may be a second ratio.

[0062] It should be noted that when the air conditioner detects that no one is in the room, it automatically adjusts its current set temperature. Although the current set temperature changes, the initial set temperature (i.e., the actual set temperature of this application) is still displayed on the air conditioner's display panel. This initial set temperature is the default temperature when the air conditioner starts working or the temperature set by the user. This setting can avoid repeated changes in the set temperature on the display panel and improve the user experience of the air conditioner.

[0063] Step S20: Control the operation of the air conditioner based on the adjusted set temperature.

[0064] After adjusting the set temperature of the air conditioner, the temperature difference between the indoor temperature and the adjusted set temperature is obtained. Based on this temperature difference, the operating parameters of the air conditioner are redefined, and the air conditioner is controlled based on these redefined operating parameters. These operating parameters can include the operating frequency of the air conditioner's compressor, the fan speed, the opening degree of the electronic expansion valve, etc.

[0065] It's understandable that when the temperature difference between the indoor temperature and the set temperature decreases, the air conditioner's operating parameters also change, thus achieving energy savings. For example, when the temperature difference decreases, the compressor's operating frequency decreases and the fan speed decreases.

[0066] In one feasible implementation, a mapping relationship between the set temperature and the operating parameters of the air conditioner can be pre-established. Subsequently, the operating parameters of the air conditioner can be determined based on the adjusted set temperature and the pre-established mapping relationship, and then the operation of the air conditioner can be controlled based on the determined operating parameters.

[0067] In another feasible implementation, a mapping relationship between the temperature difference between the indoor temperature and the set temperature and the operating parameters of the air conditioner can be pre-established. Subsequently, based on the adjusted set temperature and the indoor temperature of the room where the air conditioner is located, the current temperature difference in the indoor space can be determined. Then, based on the determined temperature difference and the pre-established mapping relationship, the operating parameters of the air conditioner can be determined, and the operation of the air conditioner can be controlled based on the determined operating parameters, thereby improving the operating efficiency of the air conditioner.

[0068] By employing the above methods, when the current set temperature of the air conditioner changes, the air conditioner can quickly and accurately control itself according to the changed current set temperature, thus providing stability to the air conditioner.

[0069] Step S30: If no one is detected in the indoor space where the air conditioner is located for a preset number of consecutive times, the air conditioner is controlled to operate according to the set operating parameters.

[0070] The preset number of times refers to the number of times the room where the air conditioner is located is unoccupied for a period of time. This preset number of times can be set according to the actual situation.

[0071] Setting operating parameters refers to the operating parameters set by the air conditioner after it detects that no one is in the room when the air conditioner is in the room for a number of consecutive preset times. These set operating parameters enable the air conditioner to operate at the lowest energy consumption level. In other words, when the air conditioner operates according to these set operating parameters, its corresponding energy consumption can be minimized, thereby achieving the energy-saving effect of the air conditioner when no one is in the room.

[0072] In one feasible implementation, during each detection process where the number of detections does not meet the preset consecutive limit, the set temperature of the air conditioner is adjusted each time the indoor space where the air conditioner is located is detected to be unoccupied, and the operating parameters of the air conditioner are determined based on the corresponding temperature difference. When the preset number of detections is reached, the air conditioner is directly controlled to operate according to the set operating parameters corresponding to the minimum energy consumption. By detecting unoccupied indoor spaces for a preset number of consecutive times, the user's usage habits and needs can be more accurately determined. Based on this, the air conditioner is controlled to operate according to the set operating parameters, ensuring both energy-saving effects and meeting the user's comfort requirements.

[0073] In another feasible implementation, if someone is detected in the indoor space during the process, the detection count is reset to zero and the detection is repeated. At this time, the air conditioner is controlled to operate according to the initial temperature setting.

[0074] For example, the preset number of times can be set to 4. If the indoor space where the air conditioner is located is detected as empty 4 times in a row, the air conditioner will be controlled to operate according to the set operating parameters, and the detection count will increase by 1 each time a detection is performed. If the indoor space is detected as empty 2 times in a row, the detection count will be recorded as 2. If someone is detected in the indoor space on the third time, the detection count will be recorded as 0. At this time, the detection of whether there is someone or not in the indoor space where the air conditioner is located will be performed again.

[0075] In this embodiment, when the indoor space where the air conditioner is located is detected to be unoccupied, the current set temperature of the air conditioner is adjusted to reduce the temperature difference between the indoor temperature and the set temperature. This helps reduce the energy consumption of the air conditioner because when the temperature difference is small, the air conditioner does not need to operate at high power to maintain the indoor temperature. Furthermore, by adjusting the set temperature, the operating frequency of the air conditioner can be further reduced, complementing the active frequency reduction mechanism and achieving more efficient energy saving. This solution does not directly limit the maximum operating frequency of the air conditioner, but indirectly affects its operating state by adjusting the set temperature. This avoids conflict with the active frequency reduction mechanism, allowing the air conditioner to maintain stable operation in various environments. Moreover, by continuously detecting unoccupied indoor spaces a preset number of times, the user's usage habits and needs can be more accurately determined. Based on this, the air conditioner is controlled to operate according to the set operating parameters, ensuring both energy saving and meeting the user's comfort requirements.

[0076] In other embodiments, in addition to adjusting the current set temperature of the air conditioner, the current set humidity, current set speed, etc. of the air conditioner can also be adjusted.

[0077] For example, in dehumidification mode, if it is detected that no one is in the room where the air conditioner is located, the current set humidity of the air conditioner is adjusted to reduce the humidity difference between the indoor humidity of the room where the air conditioner is located and the current set humidity; based on the adjusted set humidity, the air conditioner is controlled to operate; if no one is detected in the room where the air conditioner is located for a preset number of consecutive times, the air conditioner is controlled to operate according to the set operating parameters.

[0078] For example, if it is detected that no one is in the room where the air conditioner is located, the current set speed of the air conditioner is adjusted to reduce the speed difference; based on the adjusted set speed, the air conditioner is controlled to operate; if no one is detected in the room where the air conditioner is located for a preset number of consecutive times, the air conditioner is controlled to operate according to the set operating parameters.

[0079] The above methods are used to meet the energy-saving needs of air conditioners in different usage scenarios and improve the energy-saving effect of air conditioners in different scenarios.

[0080] In some embodiments of this application, reference is made to Figure 2 If the room where the air conditioner is located is detected to be unoccupied, the current set temperature of the air conditioner will be adjusted, including:

[0081] Step A11: When the air conditioner is in heating mode, if it is detected that no one is in the room where the air conditioner is located, the current set temperature of the air conditioner is lowered.

[0082] In one feasible implementation, the adjustment amount of the current set temperature of the air conditioner in heating mode can be obtained, and the current set temperature of the air conditioner can be adjusted based on the obtained adjustment amount to increase the current set temperature of the air conditioner in heating mode.

[0083] In another feasible implementation, the adjustment amount of the current set temperature of the air conditioner in heating mode can be obtained, the change amount of the current set temperature of the air conditioner can be determined based on the adjustment amount, and then the current temperature setting of the air conditioner can be adjusted based on the determined change amount to increase the current set temperature of the air conditioner in heating mode.

[0084] In another feasible implementation, when the air conditioner is in heating mode, if it is detected that there is no one in the indoor space where the air conditioner is located, the current indoor temperature and the current set temperature of the indoor space where the air conditioner is located are obtained; a first temperature difference between the indoor temperature and the current set temperature is determined; the first temperature difference is reduced according to a first ratio to obtain a reduced first temperature difference; and the set temperature value adjusted in heating mode is obtained based on the reduced first temperature difference and the current indoor temperature.

[0085] The aforementioned first ratio can be determined based on the operating mode of the air conditioner, or it can be determined based on the magnitude of the first temperature difference. For example, a mapping relationship between the operating mode of the air conditioner and / or the first temperature difference and the first ratio can be pre-established, and then the current set temperature of the air conditioner can be determined based on this mapping relationship, the current operating mode, and the current first temperature difference. The first ratio can be fixed or variable. This application uses a fixed first ratio as an example.

[0086] For example, in heating mode, if the first detected indoor temperature is 15℃ and the current set temperature is 23℃, with a first ratio of 0.5, and it is detected that no one is in the room where the air conditioner is located, the first temperature difference between the indoor temperature and the current set temperature is determined to be 8℃. The first temperature difference is then reduced according to the first ratio, resulting in a reduced first temperature difference of 4℃. At this point, the current indoor temperature can be regarded as a fixed value. Therefore, the set temperature adjusted in heating mode is 19℃, which is closer to the current indoor temperature than the set temperature of 23℃. This allows the air conditioner to achieve energy-saving effects while heating when no one is in the room.

[0087] Next, a second test is performed in heating mode. As the air conditioner runs, the indoor temperature gradually increases. If the current indoor temperature is detected to be 16℃, the current set temperature for this round is the set temperature adjusted in the previous test, which is 19℃. When it is detected that no one is in the room where the air conditioner is located, the first temperature difference between the indoor temperature and the current set temperature is determined to be 3℃. The first temperature difference is reduced according to the first ratio, resulting in a reduced first temperature difference of 1.5℃. At this point, the current indoor temperature can be regarded as a fixed value. The set temperature adjusted in heating mode is 17.5℃, which is closer to the current indoor temperature than the set temperature of 19℃. This allows the air conditioner to achieve energy-saving effects while heating when the heating mode is activated in an unoccupied environment.

[0088] And so on, conducting subsequent tests in the same manner.

[0089] In heating mode, if the room where the air conditioner is located is detected to be unoccupied, the current set temperature of the air conditioner is lowered, so that the temperature difference between the room where the air conditioner is located and the current set temperature is reduced. In other words, the adjusted set temperature is closer to the room temperature where the air conditioner is located, so that the air conditioner can achieve energy saving in heating mode.

[0090] Step A12: When the air conditioner is in cooling mode, if it is detected that no one is in the room where the air conditioner is located, increase the current set temperature of the air conditioner.

[0091] In one feasible implementation, the adjustment amount of the current set temperature of the air conditioner in cooling mode can be obtained, and the current set temperature of the air conditioner can be adjusted based on the obtained adjustment amount to increase the current set temperature of the air conditioner in cooling mode.

[0092] In another feasible implementation, the adjustment amount of the current set temperature of the air conditioner in the cooling mode can be obtained, the change amount of the current set temperature of the air conditioner can be determined based on the adjustment amount, and then the current temperature setting of the air conditioner can be adjusted based on the determined change amount to increase the current set temperature of the air conditioner in the cooling mode.

[0093] In another feasible implementation, when the air conditioner is in cooling mode, if it is detected that there is no one in the indoor space where the air conditioner is located, the current indoor temperature and the current set temperature of the indoor space where the air conditioner is located are obtained; a second temperature difference between the indoor temperature and the current set temperature is determined; the second temperature difference is reduced according to a second ratio to obtain a reduced second temperature difference; and the set temperature value adjusted in cooling mode is obtained based on the reduced second temperature difference and the current indoor temperature.

[0094] The second ratio can be determined based on the operating mode of the air conditioner, or it can be determined based on the magnitude of the second temperature difference. For example, a mapping relationship between the operating mode of the air conditioner and / or the second temperature difference and the second ratio can be pre-established, and then the current set temperature of the air conditioner can be determined based on this mapping relationship, the current operating mode, and the current second temperature difference. The second ratio can be fixed or variable, and it can also be the same as the first ratio mentioned above. This application uses a fixed second ratio as an example.

[0095] For example, in cooling mode, if the first detected indoor temperature is 25℃, the current set temperature is 19℃, the second ratio is 0.5, and it is detected that no one is in the room where the air conditioner is located, the second temperature difference between the indoor temperature and the current set temperature is determined to be 6℃. The second temperature difference is then reduced according to the second ratio, resulting in a reduced second temperature difference of 3℃. At this point, the current indoor temperature can be regarded as a fixed value. The set temperature adjusted in cooling mode is 22℃, which is closer to the current indoor temperature than the set temperature of 19℃. This allows the air conditioner to achieve energy-saving effects while cooling when the air conditioner is activated in cooling mode when no one is present.

[0096] Next, a second test is performed in heating mode. As the air conditioner runs, the indoor temperature gradually increases. If the current indoor temperature is detected to be 24℃, the current set temperature for this test is the set temperature adjusted in the previous test, which is 22℃. When it is detected that no one is in the room where the air conditioner is located, the second temperature difference between the indoor temperature and the current set temperature is determined to be 2℃. The second temperature difference is reduced according to the second ratio, resulting in a reduced second temperature difference of 1℃. At this point, the current indoor temperature can be regarded as a fixed value. Then, the set temperature adjusted in cooling mode is 23℃, which is closer to the current indoor temperature than the set temperature of 22℃. This allows the air conditioner to achieve energy-saving effects while cooling when the cooling mode is activated in the absence of people.

[0097] And so on, conducting subsequent tests in the same manner.

[0098] In cooling mode, if the room where the air conditioner is located is detected to be unoccupied, the current set temperature of the air conditioner is increased, which reduces the temperature difference between the room temperature and the current set temperature. In other words, the adjusted set temperature is closer to the room temperature, thus enabling the air conditioner to achieve energy-saving effects in cooling mode.

[0099] In this embodiment, when no one is detected in the indoor space where the air conditioner is located in heating mode, the current set temperature of the air conditioner is lowered; or, when no one is detected in the indoor space where the air conditioner is located in cooling mode, the current set temperature of the air conditioner is increased, so as to meet the energy-saving effect of different operating modes of the air conditioner.

[0100] In some embodiments of this application, if it is detected that no one is in the indoor space where the air conditioner is located, adjusting the current set temperature of the air conditioner includes:

[0101] Step B11: Check whether the indoor space where the air conditioner is located is unoccupied at preset intervals. If so, adjust the current set temperature of the air conditioner.

[0102] It should be noted that the preset duration can be set fixedly according to the experiment. The preset duration can be different or the same for different operating modes. For example, the preset duration can be 30 minutes in heating mode and 30 minutes in cooling mode, or the preset duration can be 30 minutes in both heating and cooling modes.

[0103] In one feasible implementation, in heating mode, the system checks at preset intervals whether the indoor space where the air conditioner is located is unoccupied; if so, the current set temperature of the air conditioner is lowered. Alternatively, in cooling mode, the system checks at preset intervals whether the indoor space where the air conditioner is located is unoccupied; if so, the current set temperature of the air conditioner is increased.

[0104] In another feasible implementation, in heating mode, the system checks whether the indoor space where the air conditioner is located is unoccupied at preset intervals. If so, it acquires the current indoor temperature and the current set temperature; determines a first temperature difference between the indoor temperature and the current set temperature; reduces the first temperature difference by a first ratio to obtain a reduced first temperature difference; and obtains the adjusted set temperature value in heating mode based on the reduced first temperature difference and the current indoor temperature. Alternatively, in cooling mode, the system checks whether the indoor space where the air conditioner is located is unoccupied at preset intervals. If so, it acquires the current indoor temperature and the current set temperature; determines a second temperature difference between the indoor temperature and the current set temperature; reduces the second temperature difference by a second ratio to obtain a reduced second temperature difference; and obtains the adjusted set temperature value in cooling mode based on the reduced second temperature difference and the current indoor temperature.

[0105] In this embodiment, when no one is detected indoors at preset intervals, adjusting the current set temperature of the air conditioner can reduce the operating power of the air conditioner, thereby reducing unnecessary energy consumption. This adjustment is based on the actual situation that no one is indoors, thus effectively avoiding energy waste caused by the air conditioner continuing to run when no one is present.

[0106] In some embodiments of this application, if the indoor space where the air conditioner is located is detected to be unoccupied a preset number of times, controlling the air conditioner to operate according to the set operating parameters includes:

[0107] Step S31: If no one is detected in the indoor space where the air conditioner is located for a preset number of consecutive times, control the air conditioner compressor to run at the minimum operating frequency or stop.

[0108] When the preset number of detections is reached, the air conditioner's compressor is directly controlled to operate at its minimum operating frequency or shut down. At this point, the compressor's energy consumption is minimized. By continuously detecting that the indoor space is unoccupied for a preset number of times, the user's usage habits and needs can be more accurately determined. Based on this, the air conditioner is controlled to operate at its minimum operating frequency or shut down, ensuring both energy efficiency and meeting the user's comfort requirements.

[0109] In other embodiments, while controlling the air conditioner compressor to run or stop at the minimum operating frequency, if no one is detected in the indoor space where the air conditioner is located for a preset number of consecutive times, the air conditioner fan can be controlled to run or stop at the minimum speed, so that the air conditioner can operate according to the set operating parameters corresponding to the minimum operating energy consumption, thereby improving the energy-saving effect of the air conditioner.

[0110] In some embodiments of this application, the control method for the air conditioner further includes:

[0111] Step S110: If it is detected that there are people in the indoor space where the air conditioner is located, control the air conditioner to operate based on the actual set temperature of the air conditioner. The actual set temperature is either the default temperature of the air conditioner or the temperature set when the air conditioner is turned on.

[0112] It should be noted that regardless of how the set temperature is adjusted, the actual set temperature will always be displayed on the air conditioner's display panel. This displayed set temperature will differ from the adjusted set temperature. During each detection cycle, once occupants are detected in the room, the system will revert to controlling the air conditioner according to the actual set temperature to improve cooling and heating efficiency and enhance indoor comfort when people are present.

[0113] It should be noted that the actual set temperature is the air conditioner's default temperature, or the actual set temperature can be the temperature set by the user when the air conditioner starts running.

[0114] In this embodiment of the application, if it is detected that there are people in the indoor space where the air conditioner is located, the control of the air conditioner is restored to the actual set temperature to improve the cooling and heating effect and improve the comfort of the room when there are people.

[0115] In some embodiments of this application, reference is made to Figure 3 If the room where the air conditioner is located is detected to be unoccupied, the current set temperature of the air conditioner will be adjusted, including:

[0116] Step C11: If it is detected that no one is in the indoor space where the air conditioner is located, obtain the indoor temperature of the indoor space where the air conditioner is located and the current set temperature of the air conditioner.

[0117] Step C12: Determine the third temperature difference between the indoor temperature and the currently set temperature.

[0118] Step C13: If the third temperature difference is greater than the preset temperature difference, adjust the current set temperature of the air conditioner.

[0119] It should be noted that the preset temperature difference can be set to 2℃.

[0120] It should be noted that the third temperature difference is the difference between the indoor temperature and the current set temperature. Since the indoor temperature changes in real time during the operation of the air conditioner, and the current set temperature is also adjusted according to whether there are people in the room, the third temperature difference between the indoor temperature and the current set temperature changes in real time.

[0121] The above method is suitable for situations where the indoor temperature and the set temperature are relatively close, and is generally performed after the air conditioner has been running for a period of time. Therefore, after the air conditioner has been running for a period of time, such as two hours, if it is detected that the room where the air conditioner is located is unoccupied, the indoor temperature of the room and the current set temperature of the air conditioner are obtained. A third temperature difference between the indoor temperature and the current set temperature is determined. If the third temperature difference is greater than the preset temperature difference, the current set temperature of the air conditioner is adjusted.

[0122] In this embodiment, the air conditioner's current set temperature is adjusted only when the temperature difference between the indoor temperature and the current set temperature is greater than the preset temperature difference. This avoids repeated adjustments to the air conditioner's current set temperature when the indoor temperature is close to the set temperature, thus reducing the air conditioner's energy consumption, especially when no one is in the room. Adjusting the air conditioner's current set temperature only when the indoor temperature differs from the current set temperature by a certain value further enhances the energy-saving effect.

[0123] In some embodiments of this application, the method may also be as follows: when the air conditioner is in heating mode, the system checks at preset intervals whether the indoor space where the air conditioner is located is unoccupied; if so, it obtains the indoor temperature of the indoor space where the air conditioner is located and the current set temperature of the air conditioner; it determines a third temperature difference between the indoor temperature and the current set temperature; if the third temperature difference is greater than the preset temperature difference, it reduces the third temperature difference according to a first ratio to obtain a reduced third temperature difference; and it obtains the adjusted set temperature value in heating mode based on the reduced third temperature difference and the current indoor temperature.

[0124] In some embodiments of this application, the method may also be as follows: when the air conditioner is in cooling mode, detect whether the indoor space where the air conditioner is located is unoccupied at preset intervals; if so, obtain the indoor temperature of the indoor space where the air conditioner is located and the current set temperature of the air conditioner; determine a third temperature difference between the indoor temperature and the current set temperature; if the third temperature difference is greater than the preset temperature difference, reduce the third temperature difference according to a second ratio to obtain a reduced third temperature difference; and obtain the set temperature value adjusted in cooling mode based on the reduced third temperature difference and the current indoor temperature.
