[0002] The indoor unit of a wall-mounted air conditioner typically uses a cross-flow fan to deliver air, with the user setting the fan speed based on their needs. However, when multiple users share a single air conditioner, individual user experiences of temperature and fan speed may vary.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] In the related art, windless air flow adjustment is achieved by adjusting the operating parameters of the air conditioner; however, it is not disclosed how to meet the different air flow requirements of users when multiple users share one air conditioner. Summary of the Invention

[0006] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical elements or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0007] The embodiments of the present disclosure provide a method, an apparatus, an air conditioner, and a storage medium for controlling the air output of an air conditioner, so as to meet different air output requirements when multiple users share one air conditioner.

[0022] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The accompanying drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the sake of convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0023] In the description and claims of the embodiments of the present disclosure, as well as in the accompanying drawings, the terms "first," "second," and the like are used to distinguish similar items and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate to describe the embodiments of the present disclosure herein. In addition, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0024] Unless otherwise stated, the term "plurality" means two or more.

[0025] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B means: A or B.

[0026] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0027] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0028] In an embodiment of the present disclosure, an air conditioner includes vertical oscillating blades that swing left and right for air delivery. The swinging of the blades divides the air delivery area into left and right zones. The left zone refers to the air delivery range when the blades swing from the leftmost side to the middle position, or from the middle position to the leftmost side; the right zone refers to the air delivery range when the blades swing from the rightmost side to the middle position, or from the middle position to the rightmost side. To meet the varying wind speed requirements of multiple users sharing an air conditioner, different wind speeds can be set for different air delivery zones. For example, suppose user A is in the left zone and user B is in the right zone. The two users have different wind speed requirements: user A sets a medium speed, and user B sets a high speed. When the air conditioner is oscillating for air delivery, the wind speed automatically adjusts to medium when the blades swing from the middle to the left, or from the left to the middle. The wind speed automatically adjusts to high when the blades swing from the middle to the right, or from the right to the middle. However, changes in wind speed can affect the heat exchange effect of the air, leading to fluctuations in the outlet air temperature. To address this technical issue, the air outlet of the air conditioner is controlled.

[0029] Combine Figure 1 As shown, the embodiment of the present disclosure provides a method for controlling air outlet of an air conditioner, comprising:

[0030] S101: When the air conditioner swings left and right to supply air and the air outlet speeds in the left and right air zones are different, the processor obtains the temperatures of the left and right air zones.

[0031] S102, when the temperatures of the left and right air zones are different, the processor adjusts the operating parameters of the air conditioner according to the temperature difference between the left and right air zones, the air outlet speed, and the operating mode to reduce the temperature difference between the left and right air zones.

[0032] The operating parameters of the air conditioner include one or more of the opening of the electronic expansion valve, the rotation speed of the outdoor fan, and the operating frequency of the compressor.

[0033] When an air conditioner sets different wind speeds for the left and right air zones, the wind speed changes can cause the outlet air temperature to drop or rise. Large temperature fluctuations can cause user discomfort. For example, when the air speed decreases from a higher speed to a lower speed in cooling mode, the lower wind speed reduces the amount of air that exchanges heat with the indoor heat exchanger per unit time. While the heat exchange efficiency remains unchanged, the air temperature drops, causing the outlet air temperature to fluctuate between hot and cold, which is detrimental to user health. Similarly, when the air speed decreases from a higher speed to a lower speed in heating mode, the lower wind speed reduces the amount of air that exchanges heat with the indoor heat exchanger per unit time. While the heat exchange efficiency remains unchanged, the air temperature rises, also detrimental to the user experience. Therefore, in both of these scenarios, the temperatures of the left and right air zones are acquired. Temperature sensors can be installed in each zone to monitor the temperature of each. The air conditioner's operating parameters can then be adjusted based on the temperature differences between the left and right zones.

[0034] Specifically, the air conditioner's operating parameters are adjusted based on the temperature difference between the left and right air zones, the wind speeds in those zones, and the air conditioner's operating mode. For example, when the air conditioner is in cooling mode and the vertical blades are swinging left and right to deliver air, the user may set the left air zone to high wind speed and the right air zone to low wind speed based on user needs. If the temperature in the right air zone is detected to be lower than that in the left air zone, the outlet air temperature will continue to drop after the high wind speed is reduced to low wind speed. This results in a lower perceived temperature for the user and a poor cooling experience. Therefore, the air conditioner's operating parameters can be adjusted to reduce cooling capacity and increase outlet air temperature. Adjusting the air conditioner's operating parameters may include one or more of the following: the opening of the electronic expansion valve, the speed of the outdoor fan, and the operating frequency of the compressor. For example, adjusting the operating parameters may include: reducing the opening of the electronic expansion valve to reduce refrigerant flow; reducing the speed of the outdoor fan to reduce outdoor heat exchange efficiency; reducing the operating frequency of the compressor to reduce cooling capacity; or adjusting multiple of the above operating parameters simultaneously. This prevents the temperature in the right air zone from continuing to drop.

[0035] Using the method for controlling air conditioner airflow provided by the disclosed embodiments, when the air conditioner is in a swinging airflow mode, the user can set different airflow speeds for the left and right air zones according to their needs. To ensure a roughly constant airflow temperature at different airflow speeds, the air conditioner's operating parameters are adjusted by monitoring the temperatures of the left and right air zones and combining the airflow speed and air conditioner operating mode. This reduces the temperature difference between the left and right air zones, thereby ensuring a roughly constant airflow temperature while still meeting the user's desired airflow speed, thereby improving the user experience.

[0036] Optionally, in step S101, the processor obtains the temperatures of the left and right wind zones, including:

[0037] The sensor detects the air outlet temperature at the left and right ends of the air conditioner outlet; or detects the temperature at the left and right ends of the indoor unit coil.

[0038] Here, temperature sensors can be installed on both sides of the air conditioner's air outlet to detect the air temperature at the left and right ends of the outlet. Alternatively, temperature sensors can be installed on the left and right ends of the indoor unit's coil to detect the temperature at both ends of the coil. The air conditioner's air outlet temperature or the coil's temperature can both reflect the air temperature at the left and right wind zones. This temperature can then be used to determine whether the air conditioner's operating parameters need to be adjusted.

[0039] Combine Figure 2 As shown, the embodiment of the present disclosure provides another method for controlling air outlet of an air conditioner, including:

[0040] S101: When the air conditioner swings left and right to supply air and the air outlet speeds in the left and right air zones are different, the processor obtains the temperatures of the left and right air zones.

[0041] S121, when the temperatures of the left and right air zones are different, if the operating mode is the cooling mode and the temperature difference between the first air zone and the second air zone is greater than a first threshold, the processor adjusts down the operating parameters of the air conditioner.

[0042] S122: When the temperatures of the left and right air zones are different, if the operating mode is the heating mode and the temperature difference between the first air zone and the second air zone is less than a second threshold, the processor adjusts down the operating parameters of the air conditioner.

[0043] Among them, the first wind zone is the wind zone with the highest wind speed among the left and right wind zones, and the second wind zone is the wind zone with the lowest wind speed among the left and right wind zones.

[0044] Here, airflow control is performed based on the air conditioner's different operating modes. The temperature difference ΔT = G1 - G2 is calculated, where G1 represents the temperature of the first high-speed air zone and G2 represents the temperature of the second low-speed air zone. A first threshold and a second threshold are set. For example, the first threshold T1 is 1°C and the second threshold T2 is -1°C. In cooling mode, if the temperature difference is greater than the first threshold, it indicates that the temperature of the second low-speed air zone is lower than that of the first high-speed air zone. This means that switching from high to low air speed will cause the outlet air temperature to drop sharply. In this case, to prevent the temperature in the second low-speed air zone from continuing to drop, the air conditioner's operating parameters are adjusted downward. Similarly, in heating mode, if the temperature difference is less than the second threshold, it indicates that the temperature in the second low-speed air zone is higher than that in the first high-speed air zone. This means that switching from high to low air speed will cause the outlet air temperature to rise sharply. In this case, to prevent the temperature in the low-speed air zone from continuing to rise, the air conditioner's operating parameters are adjusted downward. This ensures that the outlet air temperatures in the left and right air zones are roughly the same.

[0045] Furthermore, it should be noted that in cooling or heating mode, if the temperature difference is greater than or equal to the second threshold and less than or equal to the first threshold, the air conditioner's operating parameters are maintained. In this case, the temperature difference between the high-speed and low-speed wind zones is small and will not cause noticeable discomfort to the user. Therefore, in this case, no compensation control is performed on the air outlet temperature.

[0046] Optionally, combined Figure 3 As shown, in step S121 and step S122, the processor adjusts the operating parameters of the air conditioner, including:

[0047] S1201: When the temperature difference is greater than the first threshold and less than the third threshold, or when the temperature difference is less than the second threshold and greater than the fourth threshold, the processor reduces the opening of the electronic expansion valve.

[0048] S1202: When the temperature difference is greater than or equal to the third threshold, or less than or equal to the fourth threshold, the processor preferentially reduces the speed of the outdoor fan and then reduces the operating frequency of the compressor.

[0049] Here, the air conditioner operating parameters to be adjusted are determined based on the magnitude of the temperature difference. The third threshold value can be 3°C, and the fourth threshold value can be -3°C. Specifically, when the temperature difference is small, decreasing the opening of the electronic expansion valve is prioritized. On the one hand, adjusting the opening of the electronic expansion valve can achieve temperature compensation. On the other hand, adjusting the opening of the electronic expansion valve has a minimal impact on air conditioner operating noise. Therefore, when the temperature difference is small, decreasing the opening of the electronic expansion valve is prioritized. If the opening of the electronic expansion valve is at the minimum allowable opening, the outdoor fan speed or compressor operating frequency is adjusted. When the temperature difference is large, adjusting the outdoor fan speed takes priority, followed by adjusting the compressor operating frequency. In this case, to achieve rapid temperature compensation, the outdoor fan speed or compressor operating frequency is adjusted. The compressor operating frequency is adjusted last. On the one hand, compressor adjustment significantly impacts air conditioner noise, and on the other hand, frequent compressor adjustments can be detrimental to system stability. Therefore, adjusting the compressor operating frequency has the lowest priority.

[0050] Optionally, in step S1202, the processor preferentially reduces the outdoor fan speed and secondarily reduces the operating frequency of the compressor, including:

[0051] When the current rotation speed of the outdoor fan is greater than the minimum permissible rotation speed, the processor reduces the rotation speed of the outdoor fan.

[0052] When the current rotation speed of the outdoor fan is less than or equal to the minimum permissible rotation speed, the processor reduces the operating frequency of the compressor.

[0053] During air conditioning operation, a minimum allowable outdoor fan speed is set to ensure stable operation. When the current indoor speed exceeds the minimum allowable speed, the outdoor fan speed is reduced. When the current indoor speed is equal to or less than the minimum allowable speed, the outdoor fan speed is not adjusted, and the compressor operating frequency is reduced. This ensures temperature compensation while maintaining air conditioning system stability.

[0054] Optionally, combined Figure 4 As shown, in step S121 and step S122, the processor adjusts the operating parameters of the air conditioner, including:

[0055] S1201': When the user is sensitive to the noise of the air conditioner operation or the air conditioner is operating at night, the processor determines a target adjustment range of the electronic expansion valve according to the temperature difference.

[0056] S1202': The processor controls the electronic expansion valve to adjust its opening according to the target adjustment range.

[0057] Here, the primary consideration is the impact of adjusting air conditioning operating parameters on system noise. Among air conditioning operating parameters, adjusting the electronic expansion valve opening has the least impact on noise. Therefore, if the user requires a lower noise level, or if the system is operating in a quiet environment, such as at night, adjusting the electronic expansion valve opening for temperature compensation can be used. This ensures outlet air temperature compensation while minimizing noise impact on the user.

[0058] Optionally, in step S1201', the processor determines a target adjustment range of the electronic expansion valve according to the temperature difference, including:

[0059] The processor reduces the opening of the electronic expansion valve according to the first amplitude when the temperature difference is greater than the first threshold and less than the third threshold, or when the temperature difference is greater than the fourth threshold and less than the second threshold.

[0060] When the temperature difference is greater than or equal to the third threshold, or less than or equal to the fourth threshold, the processor reduces the opening of the electronic expansion valve according to the second amplitude.

[0061] Here, when the temperature difference is small, the opening of the electronic expansion valve is adjusted with a smaller amplitude. When the temperature difference is large, the opening of the electronic expansion valve is adjusted with a larger amplitude. This minimizes overshoot during rapid temperature compensation. The first amplitude can be 1 to 10 steps per 10 seconds, and the second amplitude can be 10 to 20 steps per 10 seconds.

[0062] Combine Figure 5 As shown, the embodiment of the present disclosure provides another method for controlling air outlet of an air conditioner, including:

[0063] S101: When the air conditioner swings left and right to supply air and the air outlet speeds in the left and right air zones are different, the processor obtains the temperatures of the left and right air zones.

[0064] S121, when the temperatures of the left and right air zones are different, if the operating mode is the cooling mode and the temperature difference between the first air zone and the second air zone is greater than a first threshold, the processor adjusts down the operating parameters of the air conditioner.

[0065] S103: When the adjusted temperature difference is less than the second threshold, the processor increases the operating parameters of the air conditioner.

[0066] S122: When the temperatures of the left and right air zones are different, if the operating mode is the heating mode and the temperature difference between the first air zone and the second air zone is less than a second threshold, the processor adjusts down the operating parameters of the air conditioner.

[0067] S104: When the adjusted temperature difference is greater than the first threshold, the processor increases the operating parameters of the air conditioner.

[0068] Here, in cooling mode, after reducing the operating parameters of the air conditioner, there may be a problem of over-adjustment. This will cause the temperature in the low wind speed zone to be higher than the temperature in the high wind speed zone. At this time, it is necessary to increase the operating parameters of the air conditioner to reduce the temperature in the low wind speed zone. In addition, after adjustment, when the temperature difference between the two wind zones is between the first threshold and the second threshold (i.e., T2≤ΔT≤T1), it indicates that the temperature difference has not changed much. At this time, the operating parameters of the air conditioner are no longer adjusted and the temperature is compensated.

[0069] Similarly, in heating mode, reducing the air conditioner's operating parameters may lead to over-adjustment. This can cause the temperature in the low-speed wind zone to be lower than that in the high-speed wind zone. In this case, the air conditioner's operating parameters need to be increased to raise the temperature in the low-speed wind zone. Furthermore, if the temperature difference between the two wind zones after adjustment falls between the first and second thresholds, the temperature difference is not significant. In this case, the air conditioner's operating parameters are no longer adjusted to compensate for the temperature.

[0070] Optionally, in step S121 and step S122, the processor adjusts the operating parameters of the air conditioner to be smaller, including:

[0071] When the absolute value of the temperature difference is greater than the first threshold and less than the third threshold, the processor reduces the rotation speed of the outdoor fan according to the third amplitude, or reduces the operating frequency of the compressor according to the fifth amplitude.

[0072] When the absolute value of the temperature difference is less than or equal to the third threshold, the processor reduces the rotation speed of the outdoor fan according to the fourth amplitude, or reduces the operating frequency of the compressor according to the sixth amplitude.

[0073] Among them, the third amplitude is smaller than the fourth amplitude, and the fifth amplitude is smaller than the sixth amplitude.

[0074] Here, when the temperature difference is small, the air conditioner's operating parameters are adjusted with a smaller amplitude. When the temperature difference is large, the air conditioner's operating parameters are adjusted with a larger amplitude. This way, overshoot is minimized during rapid temperature compensation. The third amplitude can be 1 to 10 revolutions per 10 seconds, the fourth amplitude can be 10 to 20 revolutions per 10 seconds, the fifth amplitude can be 1 to 3 Hz per 30 seconds, and the sixth amplitude can be 3 to 6 Hz per 30 seconds.

[0075] Optionally, in step S123 and step S124, the processor increases the operating parameters of the air conditioner, including:

[0076] S1203: When the temperature difference is less than the second threshold and greater than the fourth threshold, the processor preferentially increases the opening of the electronic expansion valve.

[0077] S1204: When the temperature difference is less than or equal to the third threshold, the processor increases the speed of the outdoor fan first and then increases the operating frequency of the compressor.

[0078] Here, the principle of the adjustment priority of the air-conditioning operating parameters is the same as that of step S203 above, and will not be repeated here. In addition, the adjustment range of the air-conditioning operating parameters can also refer to the adjustment range in the above text.

[0079] Optionally, in step S1204, the processor increases the speed of the outdoor fan first and then increases the operating frequency of the compressor, including:

[0080] When the current rotation speed of the outdoor fan is less than the maximum allowable noise rotation speed, the processor increases the rotation speed of the outdoor fan.

[0081] When the current rotation speed of the outdoor fan is greater than or equal to the rotation speed of the maximum allowable noise, the processor increases the operating frequency of the compressor.

[0082] To prevent excessive noise during air conditioning system operation, the maximum speed of the outdoor fan is limited. Specifically, a maximum permissible noise level is set. If the current outdoor fan speed is lower than this maximum permissible noise level, the outdoor fan speed is increased to lower the outlet air temperature. If the current outdoor fan speed is greater than or equal to this maximum permissible noise level, the compressor operating frequency is adjusted instead of the outdoor fan speed. This reduces the impact on air conditioning noise.

[0083] An embodiment of the present disclosure provides a device for controlling airflow from an air conditioner, comprising an acquisition module and an adjustment module. The acquisition module is configured to acquire the temperatures of the left and right air zones when the air conditioner is swinging left and right and the airflow speeds in the left and right air zones are different. The adjustment module is configured to adjust operating parameters of the air conditioner based on the temperature difference between the left and right air zones, the airflow speed, and the operating mode to reduce the temperature difference between the left and right air zones when the temperatures in the left and right air zones are different. The operating parameters of the air conditioner include one or more of the opening of the electronic expansion valve, the speed of the outdoor fan, and the operating frequency of the compressor.

[0084] Using the device for controlling airflow from an air conditioner provided in an embodiment of the present disclosure, when the air conditioner is in a swinging airflow mode, the user can set different airflow speeds for the left and right air zones according to their needs. To ensure a roughly constant airflow temperature at different airflow speeds, the air conditioner's operating parameters are adjusted by monitoring the temperatures of the left and right air zones and combining the airflow speed and air conditioner operating mode. This reduces the temperature difference between the left and right air zones, thereby ensuring a roughly constant airflow temperature while still meeting the user's desired airflow speed, thereby improving the user experience.
