Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to a control method for an air conditioner, an air conditioner, and a computer-readable storage medium. Background Technology

[0002] With the development of economy and technology, air conditioners are being used more and more widely, and their performance is constantly being optimized. At present, in addition to the indoor circulation module, air conditioners are also equipped with a fresh air module. The indoor circulation module can realize the internal circulation functions such as cooling, heating or air supply through the internal circulation of indoor air. When the fresh air function is turned on, the fresh air module can introduce outdoor fresh air into the room to maintain the freshness of the indoor environment.

[0003] However, in air conditioners that simultaneously have internal circulation and fresh air modules, the corresponding fans operate according to preset fixed parameters regardless of whether the internal circulation or fresh air function is activated. The fan speed is prone to being too high, causing the air conditioner's operating noise to exceed the standard noise level, while the fan speed is prone to being too low, resulting in insufficient airflow and difficulty in meeting indoor air conditioning needs. It is evident that current air conditioners with both internal circulation and fresh air functions suffer from inaccurate fan speed, making it difficult to effectively balance low noise and airflow requirements during operation. Summary of the Invention

[0020] And / or, the step of determining the operating speed as the target speed when the operating noise value is less than the set noise threshold includes:

[0021] When the operating noise value is less than the set noise threshold, the first operating speed is determined to be the first target speed, and the second operating speed is determined to be the second target speed.

[0037] This invention proposes a control method for an air conditioner. In an air conditioner equipped with a fresh air fan and a recirculation fan, a first parameter adapted to the fresh air function and the internal recirculation function determines the target speed of the target fan to be activated. During this process, the operating speed of the target fan is no longer based on a pre-set fixed speed, but can vary depending on whether the fresh air function and the internal recirculation function are activated. Based on this, it can be ensured that the noise of the fresh air fan and the internal recirculation fan will not be too high and exceed the noise limit value, while the operating speed of the fan can be matched with the current indoor air conditioning demand. Thus, the air conditioner with internal recirculation and fresh air functions can effectively balance low noise and air conditioning volume requirements during operation. Attached Figure Description

[0041] The realization of the objective, functional features and advantages of the present invention 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 invention and are not intended to limit the invention.

[0043] The main solution of this invention is as follows: First parameters corresponding to the fresh air function and the internal circulation function of the air conditioner are obtained; the first parameters indicate whether the fresh air function and the internal circulation function are respectively activated; a target fan and a target speed of the target fan are determined based on the first parameters; the target fan is the fan corresponding to the activated function of the fresh air fan and the internal circulation fan corresponding to the first parameter, and different first parameters correspond to different target fans and target speeds; the target fan is controlled to operate according to the target speed so that the total noise value of the fresh air fan and the internal circulation fan is less than a set noise threshold.

[0044] In existing technology, in air conditioners that simultaneously have internal circulation and fresh air modules, the corresponding fans operate according to pre-set fixed parameters regardless of whether the internal circulation or fresh air function is activated. The fan speed is prone to being too high, causing the air conditioner's operating noise to exceed the standard noise level. Conversely, the fan speed is prone to being too low, resulting in insufficient airflow and difficulty in meeting indoor air conditioning needs. Therefore, it is evident that current air conditioners with both internal circulation and fresh air functions suffer from inaccurate fan speed, making it difficult to effectively balance low noise and adequate airflow during operation.

[0045] The present invention provides the above-mentioned solution, which aims to achieve an effective balance between low noise and air conditioning volume requirements when an air conditioner with internal circulation and fresh air functions is running.

[0046] This invention provides an air conditioner. In this embodiment, the air conditioner is a wall-mounted air conditioner. In other embodiments, the air conditioner may also be a floor-standing air conditioner, a window air conditioner, a portable air conditioner, or a ceiling-mounted air conditioner, etc.

[0047] In this embodiment of the invention, reference is made to Figure 1 The air conditioner includes a fresh air fan 1, an internal circulation fan 2, and a control device. Both the fresh air fan 1 and the internal circulation fan 2 are connected to the control device, which controls their operation. When the fresh air fan 1 is on, it drives outdoor air into the indoor environment; when the fresh air fan 1 is off, outdoor air stops entering the indoor environment. When the internal circulation fan 2 is on, indoor air enters the air conditioner, is conditioned, and then delivered into the indoor environment; when the internal circulation fan 2 is off, indoor air stops entering the air conditioner.

[0048] Specifically, the air conditioner may also include a casing, within which are independent fresh air ducts and indoor air ducts. The fresh air duct connects the indoor environment with the outdoor environment, while the air inlet and outlet of the indoor air duct are both connected to the indoor environment. Fresh air fan 1 is located within the fresh air duct, and internal circulation fan 2 is located within the indoor air duct.

[0049] Furthermore, refer to Figure 1 The control device of the air conditioner includes a processor 1001 (e.g., CPU), a memory 1002, etc. The processor 1001 and the memory 1002 are connected via a communication bus. The memory 1002 can be a high-speed RAM or a stable memory (non-volatile memory), such as a disk storage device. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0050] Those skilled in the art will understand that Figure 1 The device structure shown does not constitute a limitation on the device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0051] like Figure 1 As shown, the memory 1002, which is a computer-readable storage medium, may include a control program for an air conditioner. Figure 1 In the device shown, the processor 1001 can be used to call the control program of the air conditioner stored in the memory 1002 and execute the relevant steps of the control method of the air conditioner in the following embodiments.

[0052] This invention also provides a control method for an air conditioner, applied to control the aforementioned air conditioner.

[0053] Reference Figure 2 This application proposes an embodiment of a control method for an air conditioner. In this embodiment, the control method for the air conditioner includes:

[0054] Step S10: Obtain the first parameters corresponding to the fresh air function and the internal circulation function of the air conditioner; the first parameters indicate whether the fresh air function and the internal circulation function are turned on respectively;

[0055] Specifically, the fresh air function and the internal circulation function of the air conditioner can operate independently, and both can be turned on or off according to the user's actual needs. In this embodiment, the first parameter can be determined based on the user's input control command. Furthermore, in other embodiments, the fresh air function and the internal circulation function can be controlled by the air conditioner based on scene parameters actually monitored in the indoor environment. Based on this, scene parameters of the indoor environment can be obtained, and the first parameter can be determined based on these scene parameters.

[0056] In this embodiment, the first parameter specifically includes one of the following: fresh air function is on and internal circulation function is on, fresh air function is on and internal circulation function is off, and fresh air function is off and internal circulation function is on.

[0057] Step S20: Determine the target fan and the target speed of the target fan according to the first parameter; the target fan is the fan corresponding to the function that is turned on in the fresh air fan and the internal circulation fan corresponding to the first parameter, and different first parameters correspond to different target fans and target speeds;

[0058] The fresh air function uses a fresh air fan, while the internal circulation function uses an internal circulation fan. Different first parameters correspond to different target fans.

[0059] Different target fans correspond to different target speeds. For example, the target speed when the target fan includes both a fresh air fan and an internal circulation fan differs from the target speed when the target fan is solely a fresh air fan. Specifically, a correspondence between the target fan or a first parameter and the target speed is established in advance based on a set noise threshold. This correspondence can be a calculated relationship, a mapping relationship, etc., and the target speed corresponding to the current target fan can be determined based on this correspondence. The target speed when the target fan is either a fresh air fan or an internal circulation fan is higher than the target speed when the target fan is both a fresh air fan and an internal circulation fan.

[0060] Step S30: Control the operation of the target fan according to the target rotation speed so that the total noise value of the fresh air fan and the internal circulation fan is less than the set noise threshold.

[0061] The noise threshold is specifically set as the maximum noise level that the combined noise level of the fresh air fan and the internal circulation fan cannot exceed. Specifically, when the target fan is the fresh air fan and the internal circulation fan is off, the noise level when the fresh air fan alone is turned on is less than the set noise threshold; when the target fan is the internal circulation fan and the fresh air fan is off, the noise level when the internal circulation fan alone is turned on is less than the set noise threshold; when the target fan is both the fresh air fan and the internal circulation fan, the noise level generated when both the fresh air fan and the internal circulation fan are turned on simultaneously is less than the set noise threshold.

[0062] In this embodiment, the target speed is the maximum speed at which the target fan is allowed to operate when the total noise level of the fresh air fan and the internal circulation fan is less than the set noise threshold. Therefore, the step of controlling the target fan's operation based on the target speed includes controlling the target fan to operate at a speed less than or equal to the maximum speed. Specifically, the target fan can be controlled to operate at a fixed speed or a variable speed less than or equal to the maximum speed. For example, when the fresh air function and / or internal circulation function are activated, if the user-set speed corresponding to the fan setting is less than or equal to the maximum speed, the corresponding target fan operates at the set speed; if the set speed is greater than the maximum speed, the corresponding target fan operates at the maximum speed.

[0063] In other embodiments, the target speed may also be the target speed value of the target fan, which can control the target fan to operate at the target speed.

[0064] This invention proposes a control method for an air conditioner. In an air conditioner equipped with a fresh air fan and a recirculation fan, the target speed of the target fan to be turned on is determined by a first parameter corresponding to the fresh air function and the internal recirculation function. During this process, the operating speed of the target fan to be turned on is no longer a fixed speed preset, but can be different depending on whether the fresh air function and the internal recirculation function are turned on. Based on this, it can be ensured that the noise of the fresh air fan and the internal recirculation fan will not be too high and exceed the noise limit value, while the operating speed of the fan can be matched with the current indoor air conditioning demand. Thus, the air conditioner with internal recirculation function and fresh air function can effectively balance low noise and air conditioning volume demand during operation.

[0065] Furthermore, based on the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, reference is made to... Figure 3 Step S20 includes:

[0066] Step S21: Determine the target fan based on the first parameter;

[0067] Different first parameters correspond to different target fans. Specifically, when the first parameter is that the fresh air function is on and the internal circulation function is on or off, the target fan is determined to be the fresh air fan; when the first parameter is that the fresh air function is off and the internal circulation function is on, the target fan is determined to be the internal circulation fan; when the first parameter is that the fresh air function is on and the internal circulation function is on, the target fan is determined to be both the fresh air fan and the internal circulation fan. In other embodiments, when the internal circulation fan and the fresh air fan are located in the same air duct, and the first parameter is that the fresh air function is on and the internal circulation function is on or off, the target fan can also be both the fresh air fan and the internal circulation fan.

[0068] Step S22: Obtain the operating speed corresponding to the target fan;

[0069] The operating speed here can be the system's default operating speed required when the target fan is turned on, or it can be the operating speed required by the user-defined target fan.

[0070] Specifically, the operating speed is obtained by acquiring the user's set rotational speed based on their own needs. Additionally, the pre-set system rotational speed corresponding to the current target fan can also be acquired as the operating speed.

[0071] Specifically, when the target fan is a fresh air fan, a first operating speed of the fresh air fan is obtained, the operating speed including the first operating speed; when the target fan is an internal circulation fan, a second operating speed of the internal circulation fan is obtained, the operating speed including the second operating speed; when the target fan includes both the fresh air fan and the internal circulation fan, the first operating speed of the fresh air fan and the second operating speed of the internal circulation fan are obtained. In this embodiment, both the first operating speed and the second operating speed are target speed values ​​set by the user for the fresh air fan and the internal circulation fan to operate when turned on.

[0072] Step S23: Determine the target speed based on the operating noise value corresponding to the operating speed and the operating speed.

[0073] Different operating speeds correspond to different operating noise levels; the higher the operating speed, the higher the operating noise level. The operating noise level corresponding to a given operating speed can be determined based on a pre-set relationship between operating speed and operating noise.

[0074] Different operating noise levels and different operating speeds correspond to different target speeds.

[0075] In this embodiment, when the operating noise value is greater than or equal to the set noise threshold, the operating speed is reduced to obtain the target speed; when the operating noise value is less than the set noise threshold, the operating speed is determined as the target speed. Specifically, the operating speed can be reduced to a preset set speed, where the total noise value of the two fans is less than the set noise threshold. Alternatively, speed adjustment parameters (such as speed adjustment amplitude and / or speed adjustment ratio) can be determined based on the noise deviation between the operating noise value and the set noise threshold, and the result obtained after reducing the operating speed according to the determined speed adjustment parameters can be used as the target speed. Here, when the operating noise value corresponding to the operating speed of the current target fan is too high, the target speed required for the target fan to operate after reducing its operating speed ensures that the total operating noise value of the two fans will not exceed the set noise threshold, regardless of whether the fresh air fan, the internal circulation fan, or both the fresh air fan and the internal circulation fan are turned on.

[0076] In other embodiments, the speed adjustment parameters can be determined by the operating noise value, and the result of adjusting the operating speed of the target fan according to the speed adjustment parameters can be used as the target speed.

[0077] In this embodiment, through steps S21 to S23, it can be ensured that no matter how many fans are turned on for indoor air conditioning, the total noise of the air conditioner's fans will not exceed the set noise threshold, and the air volume requirements for indoor air conditioning can be met.

[0078] Specifically, before step S23 and after step S22, the operating noise value corresponding to the operating speed of the target fan can be determined according to the following method:

[0079] When the target fan is a fresh air fan, the operating speed is the first operating speed. The operating noise value is determined based on the first operating speed, and different first operating speeds correspond to different operating noise values. The operating noise value tends to increase as the first operating speed increases.

[0080] When the target fan is an internal circulation fan, the operating speed is the second operating speed. The operating noise value is determined based on the second operating speed, and different second operating speeds correspond to different operating noise values. The operating noise value tends to increase as the second operating speed increases.

[0081] When the target fan includes a fresh air fan and an internal circulation fan, the operating speed includes a first operating speed and a second operating speed. The operating noise value is determined based on the first operating noise value corresponding to the first operating speed and the second operating noise value corresponding to the second operating speed. The first operating noise value increases with the increase of the first operating speed, and the second operating noise value increases with the increase of the second operating speed. Therefore, in this embodiment, the sum of the first and second operating noise values ​​can be used as the operating noise value. Alternatively, the noise deviation between the first and second operating noise values ​​and the distance between the user and the air conditioner within the air conditioner's operating space can be used to determine the weight values ​​corresponding to the first and second operating noise values, respectively. The weighted average of the first and second operating noise values ​​and their corresponding weight values ​​is then used as the operating noise value. It should be noted that the process of determining the operating noise value based on the first and second operating noise values ​​satisfies the noise superposition principle.

[0082] Specifically, the process for determining the first operating noise value mentioned above is as follows: determine the first sound power corresponding to the first operating speed, and calculate the first sound pressure level corresponding to the first operating speed as the first operating noise value based on the ratio of the first sound power to the reference power; the process for determining the second operating noise value mentioned above is as follows: determine the second sound power corresponding to the second operating speed, and calculate the second sound pressure level corresponding to the second operating speed as the second operating noise value based on the ratio of the second sound power to the reference power.

[0083] Furthermore, when the target fan includes a fresh air fan and an internal circulation fan, the operating speed includes a first operating speed and a second operating speed. Based on this, the target speed includes the first target speed of the fresh air fan and the second target speed of the internal circulation fan. Then, step S23 may include: when the operating noise value is greater than or equal to the set noise threshold, reducing the first operating speed to obtain the first target speed and determining the second operating speed as the second target speed; or, determining the first operating speed as the first target speed and reducing the second operating speed to obtain the second target speed; or, reducing the first operating speed to obtain the first target speed and reducing the second operating speed to obtain the second target speed. Additionally, step S23 may also include: when the operating noise value is less than the set noise threshold, determining the first operating speed as the first target speed and determining the second operating speed as the second target speed.

[0084] The first operating speed and / or the second operating speed can be reduced to a preset set speed. Different fans can correspond to different set speeds. The set speed is the speed value at which the total noise value of the two fans is less than the set noise threshold. In addition, the speed adjustment parameters (such as speed adjustment amplitude and / or speed adjustment ratio, etc.) can be determined according to the noise deviation between the operating noise value and the set noise threshold. The result obtained after reducing the first operating speed and / or the second operating speed according to the determined speed adjustment parameters is used as the target speed.

[0085] When two fans need to be turned on, if the total noise at the corresponding operating speeds of the two fans is too high, the target operating speed values ​​for each fan can be obtained by reducing the operating speed of one fan or both fans. Otherwise, both fans will maintain their original operating speeds to ensure that the total noise when the two fans are running at the same time does not exceed the threshold.

[0086] Furthermore, in this embodiment, in addition to obtaining the first parameter, a second parameter can also be obtained. The second parameter represents the activation priority of the fresh air function and the internal circulation function. Then, step S20 may include determining the target fan based on the first parameter and determining the target speed of the target fan based on the second parameter. Here, the second parameter can be determined by obtaining the order in which the user inputs the fresh air function activation command and the internal circulation function activation command. When the first parameter includes both the fresh air function and the internal circulation function being activated, if the user inputs the fresh air function activation command first and then the internal circulation function activation command, the priority of the fresh air function is higher than the priority of the internal circulation function; if the user inputs the internal circulation function activation command first and then the fresh air function activation command, the priority of the internal circulation function is higher than the priority of the fresh air function.

[0087] Based on this, in this embodiment, when the operating noise value is greater than the set noise threshold, a second parameter is obtained. The second parameter represents the activation priority of the fresh air function and the internal circulation function. If the second parameter indicates that the activation priority of the internal circulation function is higher than that of the fresh air function, then the first operating speed is reduced to obtain the first target speed, and the second operating speed is determined to be the second target speed. If the second parameter indicates that the activation priority of the fresh air function is higher than that of the internal circulation function, then the first operating speed is determined to be the first target speed, and the second operating speed is reduced to obtain the second target speed. Here, when the air conditioner needs to activate both the fresh air function and the internal circulation function simultaneously, the fan whose operating speed needs to be reduced is determined based on the activation priority of the fresh air function and the internal circulation function. This ensures that the total noise of the two fans after the speed reduction does not exceed the set noise threshold, while the actual airflow of the air conditioner's indoor air conditioning function can accurately meet the user's actual adjustment needs, improving the comfort of the indoor user.

[0088] In other embodiments, when the operating noise value is greater than the set noise threshold, the weight values ​​of the speed adjustment corresponding to the first operating speed and the second operating speed are determined according to the second parameter. The target speed adjustment parameters corresponding to the first operating speed and the second operating speed are determined according to the determined weight values ​​and the preset speed adjustment parameters. The first target speed and the second target speed are obtained by adjusting the first operating speed and the second operating speed according to the target speed adjustment parameters.
