Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, and in particular to an air volume adjustment control method and device for an air conditioner, an air conditioner and an electronic device. BACKGROUND

[0002] As a common device for adjusting indoor temperature and humidity, one of the core functions of an air conditioner is to circulate air through a fan system to achieve cooling or heating effects. The air volume output by the fan is a key parameter that determines the performance of the air conditioner and the comfort of the user. Users usually set the desired air supply experience by selecting different speed gears (such as low, medium, and high wind).

[0003] In traditional air conditioner air volume control, an open-loop control strategy is usually adopted. Specifically, the control system presets a fixed fan motor speed (RPM) for each speed gear. When the user selects a gear, the controller drives the fan motor to run at the corresponding preset speed. The advantage of this method is simple control and low cost.

[0004] However, the resistance (i.e. static pressure) of the air conditioner is dynamically changing. The actual air volume output by the fan is not only related to the speed, but also closely related to the total resistance of the entire air duct system. In the actual use of the air conditioner, the most common situation is that the filter screen will accumulate dust over time, causing the air duct resistance to gradually increase. In addition, different installation conditions (such as the length of the air pipe and the number of elbows) will also cause different initial resistances. As a result, under the condition of fixed fan speed, the actual output air volume will decrease with the increase of use time, and cannot be maintained at the target value set by the user. This will seriously affect the cooling / heating effect of the air conditioner, leading to a decrease in user comfort and a decrease in the energy efficiency ratio of the air conditioner.

[0005] Changes in environmental factors such as air density will also affect the output air volume of the fan. The performance of the fan is usually calibrated at standard air density. However, in actual applications, the temperature, humidity and altitude of the environment will all affect the air density. When the air density changes, even if the fan speed and air duct resistance remain unchanged, the actual output air mass flow and volume flow will also change, resulting in unstable air volume.

[0006] In summary, due to the dynamic changes in air duct resistance (static pressure) and the interference of environmental factors (such as air density), the traditional open-loop control method cannot achieve constant air volume output, i.e. it cannot guarantee that the fan can accurately output the target air volume corresponding to the set gear under any working condition, thereby affecting the performance stability of the air conditioner and the comfort experience of the user. Therefore, how to overcome the changes in system resistance and the influence of environmental factors to achieve precise and stable air volume control is a technical problem that needs to be solved. SUMMARY

[0007] The application provides an air volume regulation control method, a control device and an air conditioner, to solve at least one problem in the prior art, and to maintain the target air volume corresponding to the set gear of the fan output in the actual working condition of dynamic system static pressure, improve the comfort and energy efficiency, and prolong the service life of the system.

[0029] The following is combined Figures 1 to 3 This invention describes the airflow regulation and control method, control device, air conditioner, and electronic equipment provided in embodiments of the present invention. Before detailing the embodiments, the overall application scenario is described first. The airflow regulation and control method for the air conditioner in this invention can be applied locally to the air conditioner, to cloud platforms in the internet field, or to other types of cloud platforms in the internet field, or to third-party devices. These third-party devices may include various types such as mobile phones, tablets, laptops, in-vehicle computers, and other smart terminals.

[0030] That is, the execution subject of the air volume adjustment control method of the air conditioner provided by the embodiments of the present application can be the air conditioner body, can be the control device, can be the cloud platform in the Internet field, or other kinds of cloud platforms in the Internet field, and can also be a third-party device. The third-party device can include various types of devices such as mobile phones, tablet computers, notebook computers, vehicle-mounted computers and other smart terminals. Of course, the execution subject can also be the air volume adjustment control device of the air conditioner provided by the embodiments of the present application. The air volume adjustment control method of the air conditioner provided by the embodiments of the present application is described below with the air volume adjustment control device (hereinafter referred to as the control device) of the air conditioner as the execution subject.

[0031] As shown in Figure 1 The embodiments of the first aspect of the present application provide an air volume adjustment control method of an air conditioner. The air volume adjustment control method comprises the following steps.

[0032] S110, determining a calibration rotating speed according to the air volume and rotating speed calibration curve and the target air volume. Specifically, the storage module of the air volume adjustment control device of the air conditioner stores the air volume and rotating speed calibration curve calibrated in advance under standard working conditions, and the first determining module can determine the calibration rotating speed through the air volume and rotating speed calibration curve when the target air volume is received.

[0033] S120, determining a rotating speed correction coefficient based on the current actual rotating speed and the calibration rotating speed.

[0034] Specifically, the second determining module of the control device obtains the current actual rotating speed from the rotating speed detection unit (for example, a Hall sensor), and determines the rotating speed correction coefficient according to the relationship between the current actual rotating speed and the calibration rotating speed.

[0035] After obtaining the target "calibration rotating speed", the actual rotating speed measured by the rotating speed detection unit is compared with the target "calibration rotating speed", and a "rotating speed correction coefficient" for adjusting the rotating speed of the motor is calculated according to the deviation between the two. This step introduces a dynamic feedback adjustment mechanism. When the filter screen is clogged and other factors cause the air duct resistance to increase, the actual rotating speed will deviate from the calibration rotating speed. This step can quantify this deviation in real time and generate a correction instruction, so that the system can actively perceive and respond to changes in the actual working condition, rather than being indifferent to it as in traditional open-loop control.

[0036] S130, determining a target rotating speed based on the current actual rotating speed, the rotating speed correction coefficient and the initial resistance coefficient.

[0037] Specifically, the third determining module of the control device determines the target rotating speed according to the relationship between the current actual rotating speed, the rotating speed correction coefficient and the initial resistance coefficient.

[0038] This step is the implementation link of control adjustment, which comprehensively considers the current running state of the motor (actual speed), the dynamic adjustment amount (speed correction coefficient) calculated from the speed deviation, and the possible installation difference (initial resistance coefficient), and finally calculates the new "target speed" that the motor needs to reach, realizing accurate and self-adaptive adjustment of the fan speed. By combining the speed correction coefficient, the system can dynamically increase the speed to overcome the increased resistance, or appropriately reduce the speed when the resistance decreases, so as to ensure that the actual output air volume is always stable at the target value set by the user, regardless of the change of external resistance, thereby ensuring the constant refrigeration / heating effect and energy efficiency of the air conditioner, and significantly improving the user's comfort experience.

[0039] In the embodiment, by constructing a double-compensation closed-loop control system, accurate constant air volume output under complex and variable working conditions is realized. The method first converts the abstract target air volume into a calibrated speed that can be accurately measured as a control reference; then, by monitoring the deviation between the actual speed and the calibrated speed in real time, a speed correction coefficient is dynamically generated, so as to actively overcome the change of air duct resistance caused by factors such as filter dirt and blockage; further, the method also takes the change of air density caused by environmental factors such as altitude, temperature and humidity into the compensation model. Finally, by comprehensively considering the air duct resistance feedback and air density compensation, the system can adaptively and accurately adjust the motor speed, so as to ensure that the actual output air volume of the air conditioner can be stably maintained at the user-set value, whether in the long-term use process or in different installation and application environments, thereby bringing the user a consistent comfortable experience and ensuring the efficient and stable operation efficiency of the air conditioner.

[0040] In some embodiments of the present application, S130, based on the current actual speed, the speed correction coefficient and the initial resistance coefficient, determines the target speed, comprising: Based on the standard air density and the current actual air density, the air density deviation is determined. This step takes environmental factors into the control algorithm. By quantifying the influence of air density change, the control system can identify and compensate for the change of air supply characteristics caused by environmental changes such as altitude, temperature and humidity. This provides a key parameter for subsequent accurate compensation, breaks the limitation of traditional control methods that are only effective under standard air density, and significantly enhances the adaptability of the air conditioner to different application environments.

[0041] The target rotating speed is determined based on the current actual rotating speed, the rotating speed correction coefficient, the initial resistance coefficient and the air density deviation. Thus, a multi-dimensional adaptive control model is constructed. The model can not only overcome the change of air duct resistance (such as filter blockage) according to the rotating speed feedback, but also pre-adjust the rotating speed by using the air density deviation parameter to offset the influence of environmental changes on air volume. The double compensation mechanism ensures that the air conditioner can maintain the target air volume output extremely accurately in the case of internal resistance increase caused by long-term use, or external air density change caused by different regions and seasons. Finally, the constant air volume operation under various complex working conditions is realized, which brings the user consistent comfort experience and stable system energy efficiency.

[0042] Specifically, the third determining module of the control device determines the air density deviation based on the standard air density and the current actual air density. The target rotating speed is determined based on the current actual rotating speed, the rotating speed correction coefficient, the initial resistance coefficient and the air density deviation.

[0043] In some embodiments of the present application, determining the air density deviation based on the standard air density and the current actual air density includes taking the ratio of the current actual air density to the standard air density as the air density deviation. Thus, an efficient and simple engineering method is selected to quantify the influence of environmental changes. By calculating the ratio, the complex air density influence is quantified as a simple, dimensionless correction factor. This ratio can be directly used as a multiplier or divisor in the subsequent rotating speed calculation formula, simplifying the mathematical model of the control algorithm. For example, when the air becomes thinner (the ratio is less than 1), the adjustment amount of the rotating speed can be directly amplified by multiplying the reciprocal of the ratio. This way makes the compensation for air density changes intuitive and easy to implement in a microcontroller, improving the computational efficiency and robustness of the control system.

[0044] The present application also provides a parallel scheme: determining the air density deviation based on the standard air density and the current actual air density includes taking the difference between the standard air density and the current actual air density as the air density deviation. This embodiment provides another effective way to quantify environmental influences. This method expresses the air density deviation as an absolute difference with physical units. The difference can be directly used as the input error signal of a classic control system (especially a PID controller). The control system can dynamically generate a rotating speed adjustment amount by integrating and differentiating the error according to its size and sign, with the goal of driving the fan to operate to eliminate the air volume influence caused by the error. This way conforms to the traditional feedback control theory, making the algorithm design and debugging can draw on mature control engineering methods.

[0045] In some embodiments of the present application, the target rotating speed is determined based on the current actual rotating speed, the rotating speed correction coefficient, the initial resistance coefficient and the air density deviation, and the product of the actual rotating speed, the rotating speed correction coefficient, the initial resistance coefficient and the air density deviation is taken as the target rotating speed.

[0046] The design of the present embodiment, which multiplies a plurality of correction parameters to determine the final target rotating speed, provides an algorithm that is simple, efficient and easy to implement in a controller. Through simple multiplication, the three completely different dimensional factors, i.e., the dynamic correction (rotating speed correction coefficient) due to the change of air duct resistance, the static compensation (initial resistance coefficient) due to the difference in installation conditions, and the pre-adjustment (air density deviation) due to environmental changes, are organically integrated into a unified adjustment instruction.

[0047] The various correction coefficients jointly act to form a comprehensive and real-time scaling ratio, which directly acts on the current actual rotating speed. This ensures that the final calculated "target rotating speed" can simultaneously and accurately compensate for various disturbances from the inside (dirty and blocked) and the outside (environment), thereby achieving the clearification of the control logic and the rapidization of the adjustment response, and ultimately achieving a better constant air volume control effect at a lower calculation cost.

[0048] In some embodiments of the present application, after the target rotating speed is determined, the target rotating speed is further subjected to amplitude limiting processing based on the relationship between the target rotating speed and the maximum allowable rotating speed of the fan.

[0049] In the present embodiment, a safety protection mechanism is introduced, which can effectively prevent the situation where the target rotating speed calculated by the algorithm exceeds the physical bearing limit of the motor due to excessive system resistance (e.g., complete blockage of the filter screen). By setting an explicit upper limit (i.e., the maximum allowable rotating speed of the fan), the fan motor can be reliably protected from damage such as overheating, accelerated wear and tear, and even burning caused by over-speed operation, thereby greatly improving the long-term operation safety and hardware reliability of the air conditioner. In addition, this amplitude limiting processing also avoids the generation of excessive abnormal noise due to excessively high rotating speed of the fan under extreme working conditions, thereby protecting the hardware while ensuring the acoustic comfort of the user and the stability and robustness of the entire control system.

[0050] In some embodiments of the present application, the initial resistance coefficient is determined by the following method: In the process of running the air conditioner at the target rotating speed, a plurality of sets of actual rotating speed and actual rotating speed data pairs are obtained. Through the collection of data in actual operation, the control system can be capable of "real-time self-calibration". In this way, instead of relying on the theoretical model at the time of factory shipment or standard laboratory data, the real performance of the air conditioner in a specific installation environment (such as different pipe lengths, bends, and air outlet types) is captured. This collection method based on real data on site provides a reliable data source for the subsequent accurate calculation of the actual resistance coefficient of the system.

[0051] According to the plurality of sets of actual rotating speed and actual rotating speed data pairs, the current actual resistance coefficient is determined. This is to convert the plurality of sets of dynamic data collected into a static parameter "actual initial resistance coefficient" that can represent the inherent resistance characteristics of the current system through an algorithm. The unique static resistance brought by the specific installation environment can be accurately quantified to provide an accurate and personalized benchmark for each air volume adjustment calculation. This makes the control system "know" the physical environment characteristics from the beginning, thereby significantly improving the initial accuracy of subsequent rotating speed adjustment.

[0052] In the case where the resistance deviation between the actual resistance coefficient and the initial resistance coefficient exceeds the deviation threshold, the initial resistance coefficient is updated with the actual resistance coefficient. This introduces a long-term adaptive learning mechanism. The air conditioner can adapt to cases where the installation environment has undergone permanent or long-term changes, such as the user modifying the air duct or replacing different types of filter screens. By setting the deviation threshold, the system can distinguish between normal short-term fluctuations (such as filter screens gradually becoming dirty) and significant systematic changes. Once the latter is identified, the system updates its "initial resistance coefficient" cognition, which realizes the long-term self-learning and self-correction of the control system, ensures that the control benchmark remains accurate throughout the life cycle of the air conditioner, and avoids the decline in control accuracy due to environmental changes.

[0053] In some embodiments of the present application, based on the current actual rotating speed and the calibration rotating speed, a rotating speed correction coefficient is determined, including: taking the ratio of the calibration rotating speed to the actual rotating speed as the rotating speed correction coefficient.

[0054] When the air duct resistance increases due to filter clogging and other reasons, the "actual speed" will be lower than the "calibration speed", and the ratio of the calculated "calibration speed" to the "actual speed" (i.e. the speed correction coefficient) will be a number greater than 1. Conversely, if the air duct resistance abnormally decreases, the actual speed is higher than the calibration speed, and the coefficient will be less than 1. The advantage of this method is that it directly and linearly converts the deviation of the speed into a clear adjustment coefficient. The size of the coefficient directly reflects the degree of deviation from the target, so that the subsequent adjustment of the motor speed has a basis and is in proportion. For example, a correction coefficient of 1.2 means that the speed needs to be increased by about 20% to compensate for the loss of air volume. This direct proportional relationship not only simplifies the control algorithm and reduces the requirement for processor computing power, but also ensures that the control system responds quickly and stably, avoiding air volume fluctuations caused by excessive or insufficient correction, thereby achieving precise constant air volume control in a low-cost and highly reliable manner.
