[0036] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

Furthermore, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same elements.

[0038] In the description of this disclosure, unless otherwise stated, "multiple" means two or more; "and / or" is a term describing the relationship between related objects, indicating that there can be three relationships, for example, A and / or B can represent: A alone, A and B simultaneously, and B alone, where A and B can be singular or plural. The character " / " indicates that the related objects before and after it are in an "or" relationship.

[0039] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0040] Figure 1 This is a flowchart illustrating a control method for an air conditioner according to an exemplary embodiment, such as... Figure 1 As shown, the method is applied to an air conditioner, which includes multiple air outlets and multiple evaporators, each of which is connected to the evaporator via a connection channel. The method may include the following steps.

[0041] In step S101, the temperature of the first region of the target area is obtained.

[0042] The target area can be, for example, the area covered by the air outlet of the air conditioner. For instance, if the air conditioner is installed in room A, then the target area can be room A. The target area can also be all or part of the area in room A, and this disclosure does not specifically limit it in this regard.

[0043] In one possible implementation, the temperature of the first region can be the ambient temperature of the target region, which can be obtained by a set temperature sensor or infrared sensor, etc.

[0044] In another possible implementation, the first zone temperature can also be the object temperature of a target object within the target zone, such as a user within the target zone. In some scenarios, considering that a user's body temperature may be higher or lower upon entering the target zone, it can be determined that the user has a greater need for temperature changes (i.e., rapid cooling or rapid heating). Therefore, in this embodiment, the object temperature can also reflect the temperature demand within the target zone. That is, the object temperature of the target object can be used as the first zone temperature of the target zone, and the air conditioner's airflow can be adjusted based on the object temperature of the target object. For example, this object temperature can be obtained using an infrared sensor.

[0045] In step S102, a first temperature difference between the temperature of the first region and the first preset temperature is determined.

[0046] When the temperature of the first zone is the ambient temperature of the target zone, the first preset temperature can be, for example, the set temperature of an air conditioner, i.e., the temperature the user expects the target zone to reach. The first temperature difference is the difference between the ambient temperature and the set temperature, which can be used to determine the target zone's temperature change requirements. For example, if the first temperature difference is large, it indicates that the target zone currently needs rapid cooling or heating. If the first temperature difference is small, it indicates that the ambient temperature of the target zone is relatively close to the set temperature.

[0047] In addition, during the preset time period after the air conditioner is turned on, the temperature difference between the target area and the first preset temperature is often large. Therefore, the preset time period after the air conditioner is turned on can also indicate that the target area currently needs rapid cooling or heating.

[0048] When the temperature of the first region is the object temperature of the target object in the target region, the first preset temperature can be, for example, the preset object temperature, which is the temperature of the target object under normal conditions. The first temperature difference is the difference between the object temperature and the preset object temperature. This first temperature difference can be used to determine whether the current target object needs rapid cooling or heating. Since the target object is located in the target region, the target object's need for temperature change can be considered as the target region's need for temperature change. For example, if the first temperature difference is large, it indicates that the region where the target object is located currently needs rapid cooling or heating. If the first temperature difference is small, it indicates that the object temperature of the target object is relatively close to the preset object temperature.

[0049] Once the initial temperature difference is determined, it becomes easier to control the airflow of the air conditioner based on this initial temperature difference, so as to meet the temperature change requirements of the target area in different scenarios.

[0050] In step S103, based on the first temperature difference, a target air outlet is determined from the plurality of air outlets, and the evaporator connected to the target air outlet is taken as the target evaporator.

[0051] In this step, if the initial temperature difference is large, it indicates that the target area needs rapid cooling or heating. In this case, the number of operating air outlets and evaporators of the air conditioner can be adjusted to increase air pressure and enhance heat exchange, allowing the temperature of the target area to cool down or heat up quickly. For example, when the initial temperature difference is large, the number of air outlets can be reduced. Understandably, since the total airflow of the air conditioner remains unchanged, reducing the number of air outlets will increase the air pressure at the open outlets, thereby increasing the air delivery distance. Simultaneously, the number of operating evaporators can be reduced. Similarly, since the total refrigerant flow of the air conditioner remains unchanged, reducing the number of operating evaporators will allow excess refrigerant to flow to the operating evaporators, thereby lowering (in cooling mode) or raising (in heating mode) the outlet air temperature, enhancing heat exchange, and thus achieving energy-saving operation of the air conditioner.

[0052] If the initial temperature difference is small, it indicates that the temperature in the first area is close to the first preset temperature. In this case, the air pressure can be reduced and the comfort of the airflow can be improved by adjusting the number of operating air outlets and evaporators. For example, when the initial temperature difference is small, the number of air outlets can be increased. Since the total air volume of the air conditioner remains unchanged, increasing the number of air outlets will reduce the air pressure of each open air outlet. At the same time, the number of operating evaporators can also be increased to appropriately increase (in cooling mode) or decrease (in heating mode) the outlet temperature (so that the temperature of the target area changes slowly). At this time, the user's perceived airflow from the air conditioner is reduced, improving the comfort of the air conditioner's air delivery.

[0053] Understandably, most air conditioners are equipped with a start-stop mechanism for energy saving. This means the air conditioner shuts down when the ambient temperature is close to the set temperature and restarts when the temperature difference becomes significant. In this embodiment, when the initial temperature difference is small, the outlet air temperature can be increased (in cooling mode) or decreased (in heating mode) to better adapt the air conditioner to the reduced temperature changes in the target area, effectively reducing the number of times the air conditioner stops.

[0054] Furthermore, in this step, if the target area comprises multiple sub-areas, the temperature of each sub-area can be determined separately, thereby determining a first temperature difference between each sub-area temperature and a first preset temperature, resulting in multiple first temperature differences. Based on the first temperature difference of each sub-area, the temperature requirement of each sub-area is determined. Then, based on the temperature requirement of each sub-area, the number of air conditioner vents and evaporators can be adjusted to meet the temperature needs of different sub-areas and improve comfort.

[0055] In step S104, the air conditioner is controlled to output air based on the target air outlet and the target evaporator.

[0056] In this step, the target air outlet can be opened, and the target evaporator connected to the target air outlet can be controlled to operate, so as to meet the temperature change requirements of the target area under different scenarios.

[0057] It should be noted that in some scenarios, the air outlets and evaporators in an air conditioner are in one-to-one correspondence, meaning one air outlet is connected to one evaporator. In this case, the evaporator connected to the target air outlet can be directly controlled to operate from that target evaporator. In other scenarios, one evaporator in an air conditioner may be connected to multiple air outlets. In this case, the passage of the evaporator connected to the target air outlet can be opened (e.g., by opening the flow regulating valve on the evaporator used to control the refrigerant flow), while the other passages in that evaporator are closed.

[0058] The above technical solution allows for the identification of a target air outlet from multiple outlets and a target evaporator from multiple evaporators based on temperature changes in the first area within the target region. The airflow from the air conditioner is then controlled according to the target outlet and evaporator. This ensures that the airflow from the air conditioner is adapted to the needs of the current target area, meeting users' temperature requirements in different scenarios and improving the user experience. Furthermore, by adjusting the number of air outlets and evaporators to control the airflow, energy efficiency and comfortable air delivery are guaranteed during air conditioning operation.

[0059] The following is a detailed explanation of step S103.

[0060] In one possible implementation, step S103, which determines the target air outlet from the plurality of air outlets based on the first temperature difference, may include:

[0061] If the first temperature difference is greater than or equal to the second preset temperature, the first air outlet among the plurality of air outlets is used as the target air outlet; or, if the first temperature difference is less than the second preset temperature, the second air outlet among the plurality of air outlets is used as the target air outlet.

[0062] The number of the first air outlets is less than the number of the second air outlets.

[0063] For example, an air conditioner may include three evaporators (e.g., a left evaporator, a right evaporator, and a top evaporator) and three air outlets (e.g., a left air outlet, a right air outlet, and a top air outlet). Each air outlet is connected to one evaporator via a connecting channel. For example, channel 1 connects the left air outlet and the left evaporator, channel 2 connects the right air outlet and the right evaporator, and channel 3 connects the top air outlet and the top evaporator. When the first temperature difference is greater than or equal to a second preset temperature, it indicates that the target area has a greater demand for temperature changes. In one possible embodiment, the first air outlet may include a left air outlet and a right air outlet; that is, the left and right air outlets can be opened, and the left and right evaporators can be controlled to operate, thereby increasing the air pressure, enhancing heat exchange, and enabling the target area to cool down or heat up rapidly. In another possible embodiment, the first air outlet may include a top air outlet; that is, the top air outlet can be opened, and the top evaporator can be controlled to operate, thereby increasing the air pressure, enhancing heat exchange, and enabling the target area to cool down or heat up rapidly.

[0064] It should be noted that the above example is for illustrative purposes only. The first air outlet can also be other combinations or can be preset by the user according to their personal usage habits. This disclosure does not impose any specific limitations on this.

[0065] When the first temperature difference is less than the second preset temperature, it indicates that the target area has a lower demand for temperature changes, meaning the temperature in the first area is close to the first preset temperature. Therefore, to improve airflow comfort, the second air outlet can include a left outlet, a right outlet, and a top outlet. This means that the left, right, and top outlets are simultaneously activated to reduce the static pressure and airflow velocity of the air conditioner. Simultaneously, the left, right, and top evaporators are controlled to increase (in cooling mode) or decrease (in heating mode) the outlet temperature. Understandably, since the temperature in the first area is close to the first preset temperature, increasing (in cooling mode) or decreasing (in heating mode) the outlet temperature can mitigate temperature changes in the target area, reducing the perceived airflow and improving comfort. Furthermore, by indirectly altering the air conditioner's outlet temperature, the air conditioner becomes more adaptable to the reduced temperature changes in the target area, effectively reducing the number of times the air conditioner stops operating.

[0066] It should be noted that the above example is only for illustration. As long as the number of second air outlets is greater than the number of first air outlets, the second air outlets can also be other combination types, or can be preset by the user according to their personal usage habits. This disclosure does not impose any specific limitations on this.

[0067] In another possible implementation, considering that different areas within the target area may have different temperature change requirements in some scenarios, such as in a room with doors and windows, if the doors and windows are opened, the areas near the doors and windows may experience significant temperature changes, resulting in different temperatures in different areas of the room, a door and window sensor can be used to detect whether the doors and windows are open. If the doors and windows are detected to be open, the temperature changes in multiple sub-areas within the target area can be detected to determine whether the temperature change requirements of these sub-areas have changed.

[0068] In this embodiment, the target area includes multiple sub-areas, the first area temperature includes the temperature of each sub-area, and the first temperature difference includes the difference between the temperature of each sub-area and the first preset temperature. Determining the target air outlet from the multiple air outlets based on the first temperature difference in step S103 may include the following steps:

[0069] S1, take the first temperature difference that is greater than or equal to the second preset temperature among the multiple first temperature differences as the target temperature difference.

[0070] In this step, by determining the first temperature difference for each sub-region, a target temperature difference is determined from multiple first temperature differences. This means identifying which sub-regions currently have a greater need for temperature changes (i.e., which sub-regions require rapid heating or cooling). If the number of target temperature differences is less than the number of first temperature differences, it indicates that different sub-regions within the current target region have different needs for temperature changes.

[0071] In addition, if the first temperature difference of multiple sub-regions is less than the second preset temperature, or if the first temperature difference of multiple sub-regions is greater than or equal to the second preset temperature, it indicates that the demand for temperature change in the target area is the same. In this case, the air outlet of the air conditioner can be controlled by referring to the method in the first possible implementation method mentioned above, which will not be elaborated here.

[0072] S2, based on the target temperature difference, determine the target air outlet from among the multiple air outlets.

[0073] In this step, the location of the target sub-region corresponding to the target temperature difference can be determined. Then, based on the location of the region and a preset correspondence, the target air outlet is determined from multiple air outlets. This preset correspondence includes the correspondence between the region location and the air outlet. In real-world scenarios, users can also set or change this preset correspondence according to their personal usage habits.

[0074] For example, if the target area includes a left and a right region, and the first temperature difference corresponding to the left region is greater than or equal to the second preset temperature, meaning the left region needs rapid cooling or heating, then the target air outlet corresponding to the left region can be determined as the left air outlet and the target evaporator as the left evaporator through a preset correspondence. In this case, the left air outlet and the left evaporator can be opened to achieve strong airflow from the left side, meeting the temperature change requirements of the left region within the target area. Similarly, if the first temperature difference corresponding to the right region is greater than or equal to the second preset temperature, meaning the right region needs rapid cooling or heating, then the target air outlet corresponding to the right region can be determined as the right air outlet and the target evaporator as the right evaporator through a preset correspondence. In this case, the right air outlet and the right evaporator can be opened to achieve strong airflow from the right side, meeting the temperature change requirements of the right region within the target area.

[0075] Figure 2 This is a flowchart illustrating another control method for an air conditioner according to an exemplary embodiment, such as... Figure 2 As shown, the method may further include the following steps:

[0076] In step S105, based on the first temperature difference, the remaining air outlets of the plurality of air outlets, except for the target air outlet, are controlled to close, and the flow rate of the remaining evaporators of the plurality of evaporators, except for the target evaporator, is controlled to decrease or close.

[0077] As described above, the airflow of the air conditioner is controlled based on the target air outlet and the target evaporator. For the remaining air outlets and evaporators, in one possible implementation, they can be directly shut off. In another possible implementation, the remaining air outlets and evaporators can be controlled to close based on a first temperature difference; that is, the flow rate of the remaining air outlets and evaporators can be gradually reduced until they are completely shut off based on the first temperature difference.

[0078] Specifically, each of the evaporators is provided with a flow regulating valve for controlling the refrigerant flow. Controlling the closure of the remaining air outlets (excluding the target air outlet) among the plurality of air outlets according to the first temperature difference, and controlling the flow of the remaining evaporators (excluding the target evaporator) to decrease or close may include: cyclically executing the adjustment steps until the remaining air outlets are completely closed and the flow regulating valves of the remaining evaporators are completely closed.

[0079] The adjustment steps include:

[0080] Based on the first temperature difference, adjust the opening of the remaining air outlets and the opening of the corresponding flow regulating valves of the remaining evaporators.

[0081] In some embodiments, the adjustment opening of the air outlet and the adjustment opening of the flow control valve corresponding to different temperature differences can be preset. In this way, the adjustment opening of the remaining air outlets and the adjustment opening of the flow control valve can be determined according to the first temperature difference, and the remaining air outlets and the remaining evaporators can be adjusted accordingly.

[0082] If the remaining air outlets are not completely closed after adjustment and / or the flow regulating valves corresponding to the remaining evaporators are not completely closed, the second zone temperature of the target area is obtained, and the second temperature difference between the second zone temperature and the first preset temperature is determined, and the second temperature difference is used as the new first temperature difference.

[0083] In this way, by repeatedly adjusting the opening of the remaining air outlets and the opening of the flow regulating valves of the remaining evaporators until the remaining air outlets and the flow regulating valves of the remaining evaporators are completely closed, the air outlets of the air conditioner are made to be completely delivered through the target air outlets and the target evaporators.

[0084] For example, let's consider a target area comprising a left and a right region, where the first temperature difference in the left region is greater than or equal to a second preset temperature. As shown in the example, when the first temperature difference in the left region is greater than or equal to the second preset temperature, the left air outlet and the left evaporator can be opened. At this point, based on the first temperature difference, the opening of the right and top air outlets can be adjusted, and the flow control valves of the right and top evaporators can be adjusted to reduce the refrigerant flow to the right and top evaporators. This adjustment process is repeated until the right and top air outlets are completely closed, and the corresponding flow control valves of the right and top evaporators are completely closed, achieving full-load operation on the left side and matching the temperature change requirements of the left region within the target area.

[0085] For example, consider a target area comprising a left and a right region, where the first temperature difference corresponding to the right region is greater than or equal to a second preset temperature. As illustrated in the example, when the first temperature difference corresponding to the right region is greater than or equal to the second preset temperature, the right air outlet and the right evaporator can be opened. At this point, based on the first temperature difference, the opening of the left and upper air outlets can be adjusted, and the flow control valves of the left and upper evaporators can be adjusted to reduce the refrigerant flow to the left and upper evaporators. This adjustment process is repeated until the left and upper air outlets are completely closed, and the corresponding flow control valves of the left and upper evaporators are completely closed, achieving full-load operation on the right side and matching the temperature change requirements of the right region within the target area.

[0086] Even with the flow control valves of the remaining air outlets and evaporators completely closed, the opening of the flow control valve of the target evaporator can still be adjusted to increase the refrigerant flow into the target evaporator, so as to meet the temperature change requirements of the target area more quickly.

[0087] In summary, after determining the temperature change requirements of the target area, the corresponding air outlets can be opened according to these requirements, while other air outlets can be reduced or closed. Simultaneously, the flow valves of the evaporators corresponding to other air outlets can be reduced or closed to meet user needs while achieving energy-saving operation.

[0088] In addition, users can preset the air outlet and airflow direction after the air conditioner is turned on to meet their needs and improve their user experience.

[0089] For example, when the air conditioner is first turned on, designated air outlets can be opened and the remaining air outlets closed or reduced according to preset parameters. After the temperature in the target area has been adjusted for a period of time, and the temperature in the target area is close to the first preset temperature, all air outlets are opened to reduce the airflow speed to adapt to low-load operation. When inconsistent temperature requirements are detected in the target area or the user has activated directional airflow, the corresponding air outlet can be opened and the remaining air outlets and the flow control valve corresponding to the evaporator can be closed or reduced to achieve centralized cooling.

[0090] Figure 3 This is a flowchart illustrating another control method for an air conditioner according to an exemplary embodiment, such as... Figure 3 As shown, the method may further include the following steps:

[0091] In step S106, the location information of the target object in the target area is obtained.

[0092] To further enhance the user experience, directional airflow can be implemented based on the location of the target object within the target area. Therefore, this step involves first obtaining the location information of the target object within the target area.

[0093] In step S107, the air outlet direction of the air conditioner is adjusted according to the location information.

[0094] Based on the location information of the target object, adjust the air outlet direction of the air conditioner so that the air outlet can blow in the direction of the target object.
