[0035] The following describes the embodiments of the present application in conjunction with the accompanying drawings. The terms used in the implementation methods of the present application are only used to explain the specific embodiments of the present application and are not intended to limit the present application.
[0036] The embodiments of the present application are described below in conjunction with the accompanying drawings. Those skilled in the art will appreciate that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.
[0037] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, and this is merely a way of distinguishing the objects of the same attributes when describing them in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.
[0038] In the existing technology, the starting reliability of the air conditioner fan is low due to problems such as starting current impact and temperature rise, starting failure caused by power supply voltage fluctuation, insufficient starting adaptability under complex working conditions, and defects in the trade-off between noise and energy consumption.
[0039] Specifically, the starting current shock and temperature rise problems are mainly manifested as follows:
[0040] Traditional starting schemes typically use a high-duty-cycle PVM (PVM) voltage to drive the fan motor. This results in excessively high peak current at startup (for example, the duty cycle can exceed 30% when starting a DC fan), causing abnormal winding temperature rise. Long-term high-load operation accelerates insulation aging and can even cause winding short circuits or burnout. Especially in high-temperature environments, uncontrolled motor temperature rise can trigger overheating protection, leading to startup failure.
[0041] The main manifestations of startup failure caused by voltage power fluctuation are:
[0042] Air conditioners are often deployed in locations with unstable grid voltage, such as commercial buildings or remote areas. Voltage sags or surges can significantly impact fan startup reliability. For example, when the input voltage drops below 15% of the rated value, traditional control methods are unable to dynamically adjust startup parameters, resulting in insufficient motor torque and an inability to reach rated speed. This results in repeated starts and stops, or even complete stagnation.
[0043] The main manifestations of insufficient startup adaptability under complex working conditions are:
[0044] Existing technologies are less robust to environmental interference. For example, when an outdoor fan is started in a strong headwind, the back electromotive force generated by the reverse rotation can damage circuit components. When a DC fan is started in a flying state (e.g., after a power outage, when driven by wind), traditional control strategies cannot accurately detect rotor position and speed, which can easily lead to motor overcurrent or loss of step. Furthermore, existing solutions often rely on single sensor feedback (such as speed or current) and lack multi-parameter collaborative analysis, making them difficult to handle complex fault scenarios such as partial winding short circuits and capacitor aging.
[0045] The trade-off between noise and energy consumption is mainly manifested in the following aspects:
[0046] To suppress startup noise, some solutions use a step-by-step control strategy that gradually increases the duty cycle. However, fixed step sizes and cycle adjustments make it difficult to balance noise suppression with startup efficiency. For example, while an initial duty cycle that is too low (e.g., 14%-16%) can reduce noise, it also prolongs startup time and increases energy consumption. On the other hand, excessively large step sizes can lead to significant current fluctuations, impacting the user experience.
[0047] In summary, due to the above-mentioned problems in the prior art during the fan startup process, the startup reliability of the air conditioner fan is low. In order to solve this problem, the present application provides a startup control method and related device for an air conditioner fan.
[0048] Optional, see Figure 1 , a flow chart of a method for starting and controlling the fan of an air conditioner provided in this application. Figure 1 As shown, the air conditioner fan startup control method includes the following steps:
[0049] Step 101: When it is detected that the air conditioner fan fails to start, a second starting winding of the air conditioner fan is connected.
[0050] It should be noted that the second starting winding is another starting winding added to the air conditioner fan during the air conditioner fan design phase, based on the original first starting winding of the air conditioner fan.
[0051] In the prior art, the air conditioner fan includes a first starting winding and a running winding. The first starting winding and the running winding are adjacent to each other or differ by a specific mechanical angle on the stator core, and are grouped by the difference in winding polarity.
[0052] First, a method for determining the second resistance of the second starting winding is introduced.
[0053] The initial second resistance of the second starting winding is determined in advance based on the rated power, rated voltage and preset starting current of the air conditioner fan.
[0054] Specifically, the core logic for determining the initial second resistance of the second starting winding can be based on the equivalent circuit model and starting characteristics of the air conditioner fan. In actual operation, capacitance compensation, temperature rise limit and torque requirements must be considered at the same time, and the optimization parameters must be verified through experiments. For complex scenarios, a dynamic impedance model must be introduced for precise control.
[0055] In determining the initial second resistance value of the second starting winding, the positional relationship between the second starting winding, the first starting winding, and the running winding mentioned above must be taken into account. This positional relationship will affect the total impedance between the second starting winding and the running winding. The connection method between the second starting winding and the running winding must also be considered, specifically, whether it is a parallel structure or a series structure. At the same time, the capacitor compensation effect must also be considered. The single-phase motor introduces a phase difference through the starting capacitor, which will make the equivalent impedance complex and increase the starting torque. In this case, the complex impedance needs to be recalculated. The balance between temperature rise and efficiency must also be considered. A resistance value that is too low will result in excessive starting current, which may burn the winding. A resistance value that is too high will result in insufficient starting torque. Specific verification requires thermal simulation and experimental verification.
[0056] Then, the positional relationship between the second starting winding and the original first starting winding is introduced.
[0057] There are three possible positional relationships between the first starting winding and the second starting winding: layered, cross-type, and parallel.
[0058] Layered type: The first starting winding can be in the inner layer and the second starting winding can be in the outer layer. Alternatively, the first starting winding can be in the outer layer and the second starting winding can be in the inner layer.
[0059] For example, see Figure 2 , an example diagram of the positional relationship between the first starting winding and the second starting winding provided in this application.
[0060] like Figure 2 As shown, the figure shows the position distribution relationship in the layered position relationship, where the first starting winding is in the outer layer and the second starting winding is in the inner layer.
[0061] Cross type: The first starting winding and the second starting winding are cross-wound in the stator core slots.
[0062] Parallel type: The first starting winding and the second starting winding are wound in parallel in the stator core slots.
[0063] Finally, it should be noted that the second resistance of the second starting winding provided in this application is adjustable.
[0064] Specifically, the second resistance of the second starting winding can be determined based on the operating parameters, protection control parameters, forward and reverse wind control parameters and stability control parameters of the air conditioner fan to dynamically adjust the resistance of the second starting winding, and then the resistance of the second starting winding is adjusted according to the dynamic adjustment resistance.
[0065] The methods for dynamically adjusting the resistance value mainly include switching the winding connection method, voltage regulation technology, resistance compensation and dynamic adjustment, physical structure optimization, and intelligent adjustment technology.
[0066] Specifically, the winding connection method primarily adjusts the equivalent resistance and magnetic flux distribution by changing the physical connection method of the windings. This can be achieved through tap-type speed regulation and parallel / series winding connection. Tap-type speed regulation is achieved by providing multiple taps in the second starting winding. Switching the tap positions changes the effective number of turns in the winding, thereby adjusting the resistance and voltage distribution. Parallel / series winding connection can be achieved by connecting the second starting winding in parallel or series with the running winding to change the magnetic field phase difference and torque characteristics.
[0067] Voltage regulation primarily affects the actual resistance of the winding by changing the supply voltage or current. This adjustment method can include thyristor voltage regulation and variable frequency speed regulation. Thyristor voltage regulation works by adjusting the input voltage replication using the thyristor's conduction angle, reducing the effective voltage of the secondary starter winding, thereby changing the current and impedance. Variable frequency speed regulation works by varying the power supply frequency, affecting the motor's inductive reactance and thus adjusting the impedance.
[0068] Resistance compensation and dynamic adjustment primarily utilize additional circuitry or algorithms to dynamically compensate for resistance and optimize operating parameters. This adjustment method can include capacitor phase adjustment and closed-loop feedback control. Capacitor phase adjustment works by adjusting the starting capacitor, changing the current phase of the second starting winding, and indirectly affecting the equivalent resistance. Closed-loop feedback control utilizes Hall effect sensor feedback. The built-in Hall effect element detects speed in real time and provides feedback to the controller, dynamically adjusting the thyristor conduction angle to achieve the target resistance.
[0069] Physical structure optimization mainly reduces inherent resistance and improves efficiency by improving winding materials or designs. Specifically, copper wire can be used instead of aluminum wire, or a distributed winding design can be adopted, specifically short-distance winding or fractional slot winding, to reduce harmonic losses and lower equivalent impedance.
[0070] Intelligent resistance tuning technology combines AI algorithms and sensor data to achieve adaptive resistance adjustment. This adjustment method can include environmentally adaptive and load-predictive tuning. For example, in high-temperature environments, the system automatically reduces the supply voltage to compensate for the increase in resistance caused by rising motor winding temperature. Load-predictive tuning works by predicting load changes through current harmonic analysis and adjusting winding connections or capacitor parameters in advance to maintain stable resistance.
[0071] The second resistance value of the second starting winding is adjusted to the dynamically adjusted resistance value. This value is determined through laboratory verification testing of the air conditioner fan's operating parameters, protection control parameters, headwind and tailwind control parameters, and stability control parameters. This dynamically adjusted resistance value ensures that during startup, the current does not exceed the maximum value, thereby preventing excessive thermal stress on the fan winding.
[0072] Optionally, when the air conditioner fan determines that the fan fails to start through a multi-dimensional mechanism such as electrical parameter detection, sensor feedback or control logic judgment, the second starting winding with a second resistance value is energized.
[0073] It should be noted that this application is also applicable to harsh environments of minus 35 degrees Celsius.
[0074] Specifically, under normal temperature conditions, during the startup of the air conditioner fan, the starting winding resistance in the driver is fixed. However, in an environment of minus thirty-five degrees Celsius, the starting winding resistance will become smaller. In order to prevent the fan from starting failure, this application adds a second starting winding resistance in the driver, thereby ensuring that the air conditioner fan starts in a low temperature environment.
[0075] Step 102: Determine whether the air conditioner fan is started successfully.
[0076] In addition, after the above step 101 and before the present step 102, the following steps are further included:
[0077] Monitor the operating parameters of the second starting winding. When the operating parameters of the second starting winding meet the abnormal starting conditions, determine the dynamic adjustment resistance of the second starting winding based on the current operating parameters, protection control parameters, forward and reverse wind control parameters and stability control parameters of the air conditioner fan, and adjust the resistance of the second starting winding according to the dynamic adjustment resistance.
[0078] It should be noted that the operating parameters, protection control parameters, headwind and wind control parameters, and stability control parameters of the air conditioner fan not only determine the performance efficiency of the fan, but also directly affect the stability, energy consumption, and safety of the air conditioning system.
[0079] Among them, the operating parameters are basic performance indicators that can reflect the real-time operating status of the fan, which will affect the cooling / heating effect and energy consumption of the air-conditioning system. For example, the operating parameters include air volume, air pressure, speed, power and noise; the protection control parameters are threshold parameters that can ensure the safe shutdown of the fan under abnormal operating conditions to prevent equipment damage or fire damage. For example, the protection control parameters include temperature protection (compressor exhaust temperature, motor temperature), current protection (overcurrent threshold, phase loss protection), vibration protection (vibration amplitude threshold), pressure protection (high pressure / low pressure protection), delay protection and other parameters; the headwind and tailwind control parameters are parameters that can dynamically adjust the fan operating direction according to the ambient wind direction, which are used to optimize airflow distribution and energy efficiency. For example, the headwind and tailwind control parameters include wind direction detection, speed adjustment, blade angle adjustment, reverse control and other parameters; the stability control parameters are key parameters that can maintain the long-term stable operation of the fan, which can prevent vibration, noise or mechanical failure. For example, the stability control parameters include dynamic balancing calibration, bearing lubrication, damping adjustment, control algorithm optimization, redundant design and other parameters.
[0080] In summary, the above parameters are the core basis for the grade design and operation and maintenance of air conditioners. The operating parameters determine the performance boundaries, the protection control parameters ensure safety, the headwind and tailwind control parameters optimize energy efficiency, and the stability control parameters extend the life.
[0081] It should also be noted that operating parameters may include parameters such as the temperature, current, and voltage of the second starting winding; abnormal starting conditions may include the winding temperature exceeding a preset temperature threshold or the starting current exceeding a preset current threshold. Specifically, if an abnormality is detected during startup using the initial second resistance value of the second starting winding, the second resistance value of the second starting winding will be adjusted. The dynamically adjusted resistance value of the second starting winding will then be determined using the current operating parameters, protection control parameters, headwind and tailwind control parameters, and stability control parameters of the air conditioner fan. The initial second resistance value of the second starting winding will then be replaced with the dynamically adjusted resistance value to prevent fan startup failure.
[0082] Then, continue to execute step 102.
[0083] Optionally, whether the fan is started successfully can also be determined through multi-dimensional mechanisms such as electrical parameter detection, sensor feedback or control logic judgment.
[0084] Step 103: When it is determined that the air conditioner fan fails to start successfully, alternately connect the first starting winding and the second starting winding of the air conditioner fan until the air conditioner fan starts successfully.
[0085] When it is determined that the air conditioner fan fails to start successfully, a first starting winding with a first resistance value and a second starting winding with a dynamically adjusted resistance value are alternately energized.
[0086] It should be noted that the air conditioner fan startup control method provided herein can specifically utilize a fan IPM (Intelligent Power Module) to access different fan windings. The fan IPM is a composite module that integrates power semiconductor devices, drive circuits, and multiple protection functions, specifically designed for motor drive scenarios. For example, in a harsh environment of -35°C, the air conditioner fan windings are very small in this extremely low temperature. The IPM monitors the connection and operating status of the control windings throughout the process. When the IPM detects that the air conditioner fan is operating at the initial second resistance value or dynamically adjusted resistance value of the second winding, the windings themselves heat up. Once certain conditions are met, the IPM automatically switches the connected second starting winding to the first resistance value of the first starting winding. Alternatively, if the IPM detects that the first resistance value of the first winding is insufficient to successfully start the air conditioner fan, it automatically accesses the second starting winding. The IPM alternates between the first and second starting windings, switching between the two states until the air conditioner fan successfully starts.
[0087] In summary, the air conditioner fan startup control method provided by this application connects the air conditioner fan's second startup winding when monitoring the air conditioner fan's startup failure. After connecting the second startup winding, it is determined whether the air conditioner fan has successfully started. If startup still fails, the first and second startup windings of the air conditioner fan are alternately connected until the air conditioner fan successfully starts. By designing a second startup winding for the air conditioner fan, this application improves the reliability of the air conditioner fan startup.
[0088] Optional, see Figure 3 , another flow chart of the air conditioner fan startup control method provided by this application. Figure 3 As shown, the above-mentioned air conditioner fan startup control method further includes the following steps:
[0089] Step 201: When it is determined that the air conditioner fan is started successfully, the second starting winding connected to the air conditioner fan is switched to the first starting winding.
[0090] It should be noted that for the air conditioner fan in this application, during the start-up phase of the air conditioner fan, the first start-up winding and the second start-up winding are alternately used to start the fan. After the air conditioner fan is started, the first start-up winding is generally used to fulfill its potential auxiliary function. For example, in low-speed speed regulation mode, the start-up winding may be reconnected to the circuit to form a composite magnetic field with the running winding to assist in optimizing torque and efficiency at low speeds. For example, in fault design and redundancy design, the start-up winding may serve as a backup winding. If the running winding fails due to a fault, the start-up winding can temporarily take over the work. Therefore, here, after successful startup using the second start-up winding, the first start-up winding needs to be reconnected to the air conditioner fan so that the first start-up winding can subsequently fulfill its potential auxiliary function.
[0091] Optionally, when the air conditioner fan IPM detects that the air conditioner fan is started successfully, the second starting winding connected to the air conditioner fan is replaced with the first starting winding.
[0092] To sum up, the starting control method of the air conditioner fan provided in the present application effectively reduces the current impact during fan startup and improves the startup success rate by alternately connecting the first starting winding and the second starting winding of the fan and timely adjusting the winding resistance of the second starting winding when the fan fails to start. The starting control method of the air conditioner fan has strong adaptability, high reliability and is easy to implement, and has broad application prospects.
[0093] The above describes a method for controlling the start-up of an air conditioner fan provided by the present application. The following describes a device for executing the above method for controlling the start-up of an air conditioner fan.
