Description

Technical Field

[0001] This disclosure relates to the field of air conditioning technology, and in particular to air conditioning control methods, devices, air conditioners, storage media, and program products. Background Technology

[0002] With the development of air conditioning technology, the demand for low-energy-consumption air conditioners is increasing, leading to the development of inverter air conditioners. Inverter air conditioners can adjust the operating voltage of the air conditioner through a corresponding voltage regulation mechanism, thereby reducing the energy consumption of the air conditioner. Summary of the Invention

[0003] To overcome the problem that related technologies cannot effectively guarantee the stable operation of air conditioners while achieving efficient operation under various working conditions, this disclosure provides an air conditioner control method, device, air conditioner, storage medium, and program product, which reduces the energy consumption of air conditioners while ensuring their operational stability, and enables air conditioners to maintain efficient operation under different load conditions.

[0004] According to a first aspect of the present disclosure, a method for controlling an air conditioner is provided, comprising: determining the power loss of the air conditioner's controller before voltage adjustment in response to the current of the air conditioner satisfying a current stability condition; adjusting the output voltage of the power factor correction circuit of the controller; determining the power loss of the controller after voltage adjustment in response to the current of the air conditioner once again satisfying the current stability condition; determining power loss change information based on the power loss of the controller before voltage adjustment and the power loss after voltage adjustment; determining a target voltage in response to the power loss change information satisfying a power loss minimization condition; and controlling the voltage of the air conditioner based on the target voltage.

[0005] Since the output voltage of the power factor correction circuit in an air conditioner controller affects the controller's power loss, adjusting the output voltage of this circuit can regulate the controller's power loss. Furthermore, by analyzing how power loss changes with the adjustment of the output voltage, a target voltage that minimizes power loss can be determined. Controlling the air conditioner's voltage based on this target voltage allows the air conditioner to operate with minimal power loss, effectively reducing energy consumption and ensuring efficient operation under various load conditions. Moreover, the output voltage adjustment must be performed when the current remains stable to avoid frequent voltage adjustments and ensure stable air conditioner operation. Therefore, this technical solution reduces energy consumption while maintaining stable air conditioner operation, enabling efficient operation under different load conditions.

[0006] In some possible implementations, the method further includes: acquiring input current information of the air conditioner, the input current information including the current input current of the air conditioner and the change in input current compared to historical input current; acquiring compressor current information of the air conditioner, the compressor current information including the current compressor current and the change in compressor current compared to historical compressor current; and determining that the current of the air conditioner satisfies the current stability condition in response to the input current information and the compressor current information satisfying the current stability condition.

[0007] Based on the input current and compressor current of the air conditioner, it can be determined whether the air conditioner meets the current stability condition, thus achieving effective and accurate detection of air conditioner current stability.

[0008] In some possible implementations, determining that the air conditioner's current meets the current stability condition in response to the input current information and the compressor current information meeting the current stability condition includes: determining that the air conditioner's current meets the current stability condition in response to the duration for which the input current information meets the input current stability condition being greater than a preset duration, and the duration for which the compressor current information meets the compressor current stability condition being greater than the preset duration; the input current stability condition includes: the input current change being less than an input current change threshold, and the current input current being within a preset input current range; the compressor current stability condition includes: the compressor current change being less than a compressor current change threshold, and the current compressor current being within a preset compressor current range.

[0009] If the input current information and compressor current information meet the corresponding current conditions and remain so for a certain duration, the air conditioner can be considered to have met the current stability condition, thus achieving reliable and stable detection of air conditioner current stability.

[0010] In some possible implementations, the controller includes an inverter circuit and the power factor correction circuit, wherein determining the power loss of the controller after voltage adjustment includes: determining the power loss of the power factor correction circuit after voltage adjustment; determining the power loss of the inverter circuit after voltage adjustment; and determining the power loss of the controller after voltage adjustment based on the power loss of the power factor correction circuit and the power loss of the inverter circuit after voltage adjustment.

[0011] Considering that the power factor correction circuit and the inverter circuit are related to the power loss of the controller, the power loss of the controller can be effectively and accurately determined based on the power loss of the power factor correction circuit and the inverter circuit respectively.

[0012] In some possible implementations, the power factor correction circuit includes an inductor, an insulated-gate bipolar transistor (IGBT), and a fast recovery diode. Determining the power loss of the power factor correction circuit after voltage adjustment includes: determining the power loss of the inductor after voltage adjustment; determining the power loss of the IGBT after voltage adjustment; determining the power loss of the fast recovery diode after voltage adjustment; and determining the power loss of the power factor correction circuit after voltage adjustment based on the power loss of the inductor, the IGBT, and the fast recovery diode.

[0013] By determining the power losses of inductors, insulated-gate bipolar transistors, and fast recovery diodes, and combining the power losses of these three devices, the power loss of the power factor correction circuit can be accurately and effectively determined.

[0014] In some possible implementations, the power loss change information is the difference between the power loss of the controller before voltage adjustment and the power loss after voltage adjustment. The method further includes: in response to the difference between the power loss of the controller before voltage adjustment and the power loss after voltage adjustment being less than a preset difference, determining that the power loss change information satisfies the power loss minimization condition.

[0015] If the difference between the power loss before and after voltage adjustment is less than the preset difference, it means that the power loss has been minimized through voltage adjustment. Therefore, it can be determined that the power loss change information meets the power loss minimization condition.

[0016] In some possible implementations, controlling the voltage of the air conditioner according to the target voltage includes: determining the optimal compressor voltage of the air conditioner according to the target voltage; and controlling the compressor voltage of the air conditioner according to the optimal compressor voltage.

[0017] Since the target voltage corresponds to the minimum power loss, by determining the optimal compressor voltage of the air conditioner based on the target voltage and controlling the compressor voltage, the compressor can operate at the optimal voltage, thereby enabling the air conditioner to maintain efficient operation under different load conditions.

[0018] In some possible implementations, the method further includes: in response to the power loss change information not satisfying the power loss minimization condition, determining a voltage adjustment amount based on the power loss change information using an adaptive learning rate optimizer; determining a target output voltage of the power factor correction circuit based on the current output voltage of the power factor correction circuit and the voltage adjustment amount; and readjusting the output voltage of the power factor correction circuit based on the target output voltage.

[0019] When the power loss minimization condition is not met, the output voltage of the power factor correction circuit can be readjusted through an adaptive voltage adjustment method, thereby achieving dynamic adjustment of power loss. Furthermore, the adaptive learning rate optimizer has the characteristic of adaptively adjusting the learning rate, which can avoid the tediousness and difficulty of manually setting the learning rate. Compared with some other adjustment algorithms, its processing is also more efficient. Therefore, implementing adaptive adjustment of the output voltage of the power factor correction circuit based on the adaptive learning rate optimizer can improve the voltage adjustment effect.

[0020] In some possible implementations, determining the voltage adjustment amount based on the power loss change information using an adaptive learning rate optimizer includes: updating the adaptive parameters used to determine the voltage adjustment amount in the adaptive learning rate optimizer based on the power loss change information, wherein the adaptive parameters include first-order moment parameters and second-order moment parameters; and determining the voltage adjustment amount based on the updated adaptive parameters using the adaptive learning rate optimizer.

[0021] By associating power loss variation information with the adaptive parameters in the adaptive learning rate optimizer, the adaptive parameters can be continuously updated based on dynamic power loss variation information, thereby determining the voltage adjustment amount that conforms to the actual operating conditions of the air conditioner.

[0022] In some possible implementations, the adaptive learning rate optimizer is pre-configured with a limit range for the voltage adjustment amount. The step of determining the voltage adjustment amount based on the updated adaptive parameters through the adaptive learning rate optimizer includes: determining the voltage adjustment amount based on the updated adaptive parameters and the limit range for the voltage adjustment amount through the adaptive learning rate optimizer, wherein the voltage adjustment amount is within the limit range for the voltage adjustment amount.

[0023] By pre-configuring the voltage adjustment range in the adaptive learning rate optimizer, the adaptive learning rate optimizer can determine the voltage adjustment amount based on the range, avoiding voltage jumps caused by excessive voltage adjustment and improving the safety and reliability of air conditioning operation.

[0024] In some possible implementations, determining the target output voltage of the power factor correction circuit based on the current output voltage of the power factor correction circuit and the voltage adjustment amount includes: obtaining a preset voltage range; and determining the target output voltage of the power factor correction circuit based on the current output voltage of the power factor correction circuit, the voltage adjustment amount, and the preset voltage range, wherein the target output voltage is located within the preset voltage range.

[0025] By combining the preset voltage range, voltage adjustment amount, and current output voltage, the target output voltage can be determined, and the output voltage of the power factor correction circuit can be constrained within the preset voltage range. This avoids the impact on the operational stability and safety of the air conditioner due to the output voltage of the power factor correction circuit being too large or too small, thereby improving the operational stability and safety of the air conditioner.

[0026] According to a second aspect of the present disclosure, an air conditioner control device is provided, the air conditioner control device being configured to perform the air conditioner control method described in the first aspect of the present disclosure.

[0027] According to a third aspect of the present disclosure, an air conditioner control device is provided, comprising: a processor; a memory for storing processor-executable instructions; wherein the processor is configured to execute the executable instructions to implement the air conditioner control method described in the first aspect of the present disclosure.

[0028] According to a fourth aspect of the present disclosure, a computer-readable storage medium is provided that stores computer program instructions thereon, which, when executed by a processor, implement the air conditioning control method described in the first aspect of the present disclosure.

[0029] According to a fifth aspect of the present disclosure, a computer program product is provided, including a computer program that, when executed by a processor, implements the air conditioning control method described in the first aspect of the present disclosure.

[0030] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0031] The accompanying drawings, which are incorporated in and form a part of this specification, illustrate embodiments consistent with this disclosure and, together with the description, serve to explain the principles of this disclosure.

[0032] Figure 1 This is a flowchart illustrating an air conditioner control method according to an exemplary embodiment.

[0033] Figure 2 This is a schematic diagram illustrating the control flow of an air conditioner according to an exemplary embodiment.

[0034] Figure 3 This is a block diagram illustrating an air conditioner control device according to an exemplary embodiment.

[0035] Figure 4 This is a block diagram illustrating an air conditioner according to an exemplary embodiment. Detailed Implementation

[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.

[0037] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0038] As mentioned in the background section, variable frequency air conditioners can adjust the operating voltage of the air conditioner through a corresponding voltage adjustment mechanism, thereby reducing the energy consumption of the air conditioner.

[0039] In related technologies, the voltage adjustment mechanism of inverter air conditioners uses preset control parameters or simple proportional control. This method cannot adaptively adjust the voltage according to the real-time operating status, making it difficult for the air conditioner to achieve optimal energy efficiency under various operating conditions. Furthermore, when faced with rapid changes in load and environmental conditions, system oscillations are prone to occur, affecting the stable operation of the air conditioner.

[0040] Therefore, the air conditioning control solutions of related technologies cannot achieve efficient operation of air conditioning under various working conditions while effectively ensuring the stable operation of the air conditioning.

[0041] Based on this, the present disclosure provides a technical solution. Since the output voltage of the power factor correction circuit of the air conditioner controller affects the power loss of the controller, adjusting the output voltage of the power factor correction circuit can regulate the power loss of the controller. Furthermore, by analyzing the change in power loss with the adjustment of the output voltage of the power factor correction circuit, a target voltage that meets the condition of minimizing power loss can be determined. By controlling the air conditioner voltage based on the target voltage, the air conditioner can operate under the condition of minimizing power loss, thereby effectively reducing the energy consumption of the air conditioner and enabling the air conditioner to maintain efficient operation under different load conditions.

[0042] Furthermore, the adjustment of the output voltage must be performed when the current meets the current stability condition, which can avoid frequent voltage adjustments and ensure the stability of the air conditioner operation.

[0043] Therefore, this technical solution can reduce the energy consumption of air conditioners while ensuring their operational stability, enabling them to maintain efficient operation under different load conditions.

[0044] The technical solutions of this disclosure can be applied to inverter air conditioners, as well as other air conditioners with voltage control mechanisms.

[0045] Figure 1 This is a flowchart illustrating an air conditioner control method according to an exemplary embodiment, such as... Figure 1 As shown, the control method includes the following steps: Step S11: In response to the current of the air conditioner meeting the current stability condition, determine the power loss of the air conditioner controller before voltage adjustment.

[0046] Step S12: Adjust the output voltage of the power factor correction circuit of the controller.

[0047] Step S13: In response to the current of the air conditioner once again satisfying the current stability condition, determine the power loss of the controller after voltage adjustment.

[0048] Step S14: Determine the power loss change information based on the power loss of the controller before voltage adjustment and the power loss after voltage adjustment.

[0049] Step S15: In response to the power loss change information satisfying the power loss minimization condition, determine the target voltage.

[0050] Step S16: Control the voltage of the air conditioner according to the target voltage.

[0051] In this embodiment of the disclosure, the current of the air conditioner meets the current stability condition, which can be a prerequisite for adjusting the output voltage of the power factor correction circuit and determining whether the power loss is minimized.

[0052] It is understandable that when the current of the air conditioner meets the current stability condition, the relevant parameters detected are more accurate, and the state of the air conditioner is also more stable. Therefore, voltage adjustment under this condition can ensure the stable operation of the air conditioner.

[0053] Therefore, the method may further include: detecting whether the current of the air conditioner meets the current stability condition; if yes, executing step S11; if not, continuing to detect whether the current of the air conditioner meets the current stability condition.

[0054] As an optional implementation, detecting whether the air conditioner is in a stable current state includes: acquiring the input current information of the air conditioner, including the current input current of the air conditioner and the change in input current compared to historical input current; acquiring the compressor current information of the air conditioner, including the current compressor current and the change in compressor current compared to historical compressor current; and determining that the air conditioner is in a stable current state based on the input current information and the compressor current information.

[0055] In this implementation, based on the input current and compressor current of the air conditioner, it is determined whether the air conditioner meets the current stability condition, which can achieve effective and accurate detection of air conditioner current stability.

[0056] In some embodiments, the controller is electrically connected to the compressor. The controller may include a rectifier circuit, a power factor correction circuit, and an inverter circuit. The input terminal of the rectifier circuit can be electrically connected to the power supply of the air conditioner to receive the supply current / voltage; the output terminal of the rectifier circuit can be connected to the input terminal of the power factor correction circuit; the output terminal of the power factor correction circuit can be connected to the input terminal of the inverter circuit; and the output terminal of the inverter circuit can be electrically connected to the compressor.

[0057] The power factor correction circuit, also known as a PFC (Power Factor Correction) circuit, has been experimentally verified to have a minimum total power loss point within a specific range of its output voltage. Therefore, by adjusting the output voltage of the PFC circuit, the total power loss of the air conditioner can be reduced, thus achieving lower energy consumption.

[0058] The rectifier circuit, power factor correction circuit, and inverter circuit are all mature air conditioner controller circuits in this field. Therefore, the specific circuit structure and function of each circuit will not be described in detail here. You can refer to the mature technologies in this field.

[0059] In some embodiments, the input current of the air conditioner may be the input current of the rectifier circuit.

[0060] In some embodiments, the compressor current may also be the compressor's input current / operating current.

[0061] In some embodiments, the historical input current and the historical compressor current can be the current at a historical moment (e.g., the previous moment).

[0062] It is understandable that the current input current and current compressor current are currents detected in real time.

[0063] Furthermore, by inputting current information and compressor current information, it can be determined whether the air conditioner meets the current stability condition.

[0064] As an optional implementation, determining that the air conditioner's current meets the current stability condition in response to the input current information and compressor current information meeting the current stability condition includes: determining that the air conditioner's current meets the current stability condition in response to the duration that the input current information meets the input current stability condition being greater than a preset duration, and the duration that the compressor current information meets the compressor current stability condition being greater than a preset duration; the input current stability condition includes: the input current change is less than an input current change threshold, and the current input current is within a preset input current range; the compressor current stability condition includes: the compressor current change is less than a compressor current change threshold, and the current compressor current is within a preset compressor current range.

[0065] In this implementation, when the input current information and the compressor current information meet the corresponding current conditions and reach a certain duration, the air conditioner can be considered to meet the current stability condition, thus achieving reliable and stable detection of the air conditioner current stability.

[0066] It is understandable that the threshold for input current change, the threshold for compressor current change, the preset input current range, and the preset compressor current range can be set based on experience, actual measurement, simulation test, etc., and no specific value is limited here.

[0067] As an example, the input current stability condition can be expressed as:

[0068] Among them, I k+1 I represents the input current detected in the (k+1)th time (e.g., the current input current). k This represents the input current during the k-th detection (e.g., historical input current). I represents the threshold value for the change in input current. max and I min This indicates the maximum and minimum input current within the preset input current range.

[0069] As an example, the compressor current stabilization condition can be expressed as:

[0070] Among them, i k+1 i represents the compressor current detected in the (k+1)th time (e.g., the current compressor current). k This represents the compressor current during the k-th detection (e.g., historical compressor current). i represents the threshold value for the change in input current. max and imin This indicates the maximum and minimum input current within the preset compressor current range.

[0071] Regarding a duration greater than the preset duration, it can be expressed as: T > T th Where T represents the duration, T th This indicates the preset duration, which can be determined based on experience, actual measurement, simulation test, etc., and no specific value is limited here.

[0072] It is understood that, in addition to the above-described current stabilization condition implementation method, other current stabilization condition implementation methods may also be used, and no limitation is made in the embodiments disclosed herein.

[0073] Furthermore, the power loss of the air conditioner controller before voltage adjustment can be understood as the controller power loss under the condition of current stability.

[0074] In some embodiments, the power loss of the controller before voltage regulation may include: the power loss of the power factor correction circuit before voltage regulation and the power loss of the inverter circuit before voltage regulation.

[0075] Therefore, determining the power loss of the controller before voltage regulation can include: determining the power loss of the power factor correction circuit before voltage regulation; determining the power loss of the inverter circuit before voltage regulation; and determining the power loss of the controller before voltage regulation based on the power loss of the power factor correction circuit and the power loss of the inverter circuit before voltage regulation.

[0076] Considering that the power factor correction circuit and the inverter circuit are related to the power loss of the controller, the power loss of the controller can be effectively and accurately determined based on the power loss of the power factor correction circuit and the inverter circuit respectively.

[0077] Regarding the power loss P of the inverter circuit INVERTER It can be represented as: P INVERTER =P sw +P son =P t +P c +P r +P son .

[0078] Among them, P sw P represents the operating loss of a switching transistor (such as a diode). son P represents the conduction loss of the switching transistor. t P represents the power loss during the turn-on operation of the switching transistor. c P represents the loss during the turn-off action of the switching transistor. rThis represents the reverse recovery loss of the switching transistor.

[0079] In some embodiments, the power factor correction circuit may include an inductor, an insulated-gate bipolar transistor (IGBT), and a fast recovery diode. Accordingly, the power loss of the power factor correction circuit may be related to the power losses of the inductor, the IGBT, and the fast recovery diode, respectively.

[0080] Therefore, determining the power loss of the power factor correction circuit before voltage adjustment includes: determining the power loss of the inductor before voltage adjustment; determining the power loss of the insulated-gate bipolar transistor before voltage adjustment; determining the power loss of the fast recovery diode before voltage adjustment; and determining the power loss of the power factor correction circuit before voltage adjustment based on the power loss of the inductor, the power loss of the insulated-gate bipolar transistor, and the power loss of the fast recovery diode before voltage adjustment.

[0081] In this implementation, by determining the power losses of the inductor, the insulated gate bipolar transistor, and the fast recovery diode, and combining the power losses of these three devices, the power loss of the power factor correction circuit can be accurately and effectively determined.

[0082] The power losses of inductors, insulated-gate bipolar transistors, and fast recovery diodes can be calculated using the corresponding methods. The following section will provide a detailed introduction to the power loss calculation methods for power factor correction circuits.

[0083] Regarding the power loss P of the inductor L Losses can be divided into copper losses and iron losses, which can be specifically represented as follows:

[0084] Among them, P cu P represents copper loss. Fe Indicates iron loss, i L R represents the inductor current. L P represents the internal resistance of the inductor. c V represents the loss per unit volume of the magnetic core. e This represents the volume of the inductor core.

[0085] The insulated gate bipolar transistor, also known as an IGBT, has a power loss P. IGBT It can be divided into switching loss and conduction loss, which can be specifically expressed as:

[0086] Among them, P rf P represents the switching loss. onP represents the conduction loss. out f represents the output power. s Indicates the operating frequency, t r Indicates the start-up time, t f Indicates the off-rise time. U represents efficiency. in U represents the input voltage (of the IGBT). o This represents the output voltage (of the IGBT), V. Qce This indicates the conduction voltage drop.

[0087] Regarding fast recovery diodes, their English name is FRD (Fast recovery diode), and their power loss P... FRD It can be divided into reverse recovery loss and conduction loss, which can be specifically expressed as:

[0088] Among them, P Dr P represents the reverse recovery loss. Don U represents the conduction loss, and U represents the voltage across the fast recovery diode. rm Represents the reverse recovery current, t rr Indicates the reverse recovery time, f s Indicates the operating frequency (of the FRD), V F P represents the on-state voltage drop. out U represents the output power (of the FRD). o This indicates the output voltage (of the FRD).

[0089] It is understood that the definitions and methods of obtaining the various parameters in the above calculation formulas can refer to mature technologies in this field, and will not be described in detail here.

[0090] Furthermore, the total power loss P of the controller total It can be represented as:

[0091] In some embodiments, based on the formula for total power loss, specific circuit parameters and corresponding values ​​are substituted, and the formula is mathematically processed. Furthermore, by differentiating the total power loss with the output voltage of the PFC circuit, it can be found that within a specific range of the PFC circuit's output voltage, the total power loss value has a minimum point. Therefore, there exists an optimal output voltage value that minimizes the total power loss of the controller.

[0092] Therefore, in this embodiment of the disclosure, power loss can be minimized by adjusting the output voltage of the power factor correction circuit.

[0093] Therefore, in step S12, the output voltage of the power factor correction circuit of the controller is adjusted.

[0094] In some embodiments, if the air conditioner's current is meeting the current stability condition for the first time, the output voltage of the power factor correction circuit can be directly adjusted in step S12. If the air conditioner's current is not meeting the current stability condition for the first time, it is necessary to determine the controller power loss after the last voltage adjustment. Based on the difference between the controller power loss after the last voltage adjustment and the current controller power loss, power loss change information is determined. If the power loss change information does not meet the power loss minimization condition, step S12 is executed.

[0095] That is, in this embodiment of the disclosure, the adjustment condition for the output voltage is: the power loss change information does not meet the power loss minimization condition.

[0096] Furthermore, if the air conditioner's current is meeting the current stability condition for the first time, the output voltage can be adjusted according to the set initial adjustment value during the initial adjustment, or it can be adjusted through a corresponding optimizer. The implementation method of adjusting through the optimizer will be described in subsequent embodiments. If the air conditioner's current is not meeting the current stability condition for the first time, the voltage can be adjusted based on the optimizer and power loss change information. The specific adjustment method will be described in subsequent embodiments.

[0097] In some embodiments, the adjustment of the output voltage of the power factor correction circuit can be achieved by controlling the duty cycle of the input signal of the power factor correction circuit, as can be found in mature technologies in the field.

[0098] Furthermore, after adjusting the output voltage of the controller's power factor correction circuit, it is necessary to re-detect whether the air conditioner's current meets the current stability condition.

[0099] Therefore, in step S13, when the current of the air conditioner meets the current stability condition again, the power loss of the controller after voltage adjustment is determined.

[0100] The calculation method for the power loss of the controller after voltage adjustment is the same as the calculation method for the power loss before voltage adjustment in the previous embodiment. The difference is that the specific parameters obtained are the parameters of the controller after voltage adjustment, which will not be repeated here.

[0101] For example, determining the power loss of the controller after voltage adjustment may include: determining the power loss of the power factor correction circuit after voltage adjustment; determining the power loss of the inverter circuit after voltage adjustment; and determining the power loss of the controller after voltage adjustment based on the power loss of the power factor correction circuit and the power loss of the inverter circuit after voltage adjustment.

[0102] Furthermore, determining the power loss of the power factor correction circuit after voltage adjustment may include: determining the power loss of the inductor after voltage adjustment; determining the power loss of the insulated-gate bipolar transistor after voltage adjustment; determining the power loss of the fast recovery diode after voltage adjustment; and determining the power loss of the power factor correction circuit after voltage adjustment based on the power loss of the inductor, the power loss of the insulated-gate bipolar transistor, and the power loss of the fast recovery diode.

[0103] In step S14, the power loss change information can be the difference between the power loss of the controller before voltage adjustment and the power loss after voltage adjustment.

[0104] As an example, △P=P i+1 -P i Where ΔP is the change in power loss, P i P represents the power loss of the controller before voltage regulation. i+1 This refers to the power loss of the controller after voltage adjustment.

[0105] In this embodiment of the disclosure, the power loss minimization condition can be that the power loss change value is less than a preset difference.

[0106] Therefore, as an optional implementation, step S15 includes: in response to the controller determining that the power loss change information satisfies the power loss minimization condition when the difference between the power loss before voltage adjustment and the power loss after voltage adjustment is less than a preset difference.

[0107] In this implementation, if the difference between the power loss before and after voltage adjustment is less than a preset difference, it indicates that the power loss has been minimized by voltage adjustment. Therefore, it can be determined that the power loss change information meets the power loss minimization condition.

[0108] Furthermore, if the power loss change information satisfies the power loss minimization condition, the target voltage can be determined. The target voltage can be the compressor's current output voltage.

[0109] In step S14, controlling the voltage of the air conditioner according to the target voltage may include: determining the optimal compressor voltage of the air conditioner according to the target voltage; and controlling the compressor voltage of the air conditioner according to the optimal compressor voltage.

[0110] In this implementation, since the target voltage corresponds to the minimized power loss, by determining the optimal compressor voltage of the air conditioner based on the target voltage and controlling the compressor voltage, the compressor can operate at the optimal voltage, thereby enabling the air conditioner to maintain efficient operation under different load conditions.

[0111] In some embodiments, the optimal compressor voltage of the air conditioner can be directly the target voltage.

[0112] In some embodiments, the optimal compressor voltage of the air conditioner can be the voltage obtained by adding or subtracting the corresponding control error from the target voltage.

[0113] Alternatively, other relationships may exist between the target voltage and the optimal compressor voltage, which are not specified here.

[0114] Furthermore, by controlling the compressor voltage of the air conditioner at the optimal compressor voltage, the air conditioner can maintain efficient and stable operation under various load conditions, and reduce the energy consumption of the air conditioner.

[0115] In some embodiments, the compressor voltage can be controlled by controlling the compressor input voltage, input current, etc. For details, please refer to the mature technologies in this field, which will not be described in detail here.

[0116] In some embodiments, the method further includes: in response to the power loss change information not satisfying the power loss minimization condition, determining a voltage adjustment amount based on the power loss change information using an adaptive learning rate optimizer; determining a target output voltage of the power factor correction circuit based on the current output voltage of the power factor correction circuit and the voltage adjustment amount; and readjusting the output voltage of the power factor correction circuit based on the target output voltage.

[0117] In this implementation, when the power loss minimization condition is not met, the output voltage of the power factor correction circuit can be readjusted through an adaptive voltage adjustment method, thereby achieving dynamic adjustment of power loss. Furthermore, the adaptive learning rate optimizer has the characteristic of adaptively adjusting the learning rate, which can avoid the tediousness and difficulty of manually setting the learning rate. Compared with some other adjustment algorithms, its processing is also more efficient. Therefore, implementing adaptive adjustment of the output voltage of the power factor correction circuit based on the adaptive learning rate optimizer can improve the voltage adjustment effect.

[0118] The adaptive learning rate optimizer is called Adam, short for Adaptive Moment Estimation. Adam is an adaptive learning rate optimization algorithm based on first-order and second-order moment estimation. Its core idea is to dynamically adjust the learning rate of each parameter using the first-order and second-order moment estimates of the gradient, thereby accelerating the convergence process. The Adam algorithm requires relatively few memory resources, reducing resource consumption. The Adam algorithm exhibits good performance when dealing with sparse gradients.

[0119] In this embodiment, power loss variation information can be used as input to Adam, enabling Adam to determine and output a voltage adjustment amount. Furthermore, using this voltage adjustment amount, the output voltage of the power factor correction circuit can be readjusted.

[0120] It is understandable that the output voltage adjustment in step S12 can also be implemented based on an adaptive learning rate optimizer. Therefore, before the optimal compressor voltage is determined, the parameters of the adaptive learning rate optimizer will be continuously updated and used to determine the voltage adjustment amount for each output voltage adjustment.

[0121] As an optional implementation, the voltage adjustment amount is determined based on power loss change information using an adaptive learning rate optimizer, including: updating the adaptive parameters used to determine the voltage adjustment amount in the adaptive learning rate optimizer based on the power loss change information, the adaptive parameters including first-order moment parameters and second-order moment parameters; and determining the voltage adjustment amount based on the updated adaptive parameters using the adaptive learning rate optimizer.

[0122] In this implementation, power loss variation information is associated with adaptive parameters in the adaptive learning rate optimizer, so that the adaptive parameters can be continuously updated based on dynamic power loss variation information, thereby determining the voltage adjustment amount that conforms to the actual operating conditions of the air conditioner.

[0123] As an example, the adaptive learning rate optimizer needs to update adaptive parameters, including: First-order moment parameter m n : Second-order moment parameter v n : .

[0124] Here, n represents the number of updates (iterations), for example, n=3 represents the 3rd update. β1 and β2 represent hyperparameters, which are fixed values. g represents power loss variation information (i.e., the amount of power loss change). It can be understood that g can be 0 during the first output voltage adjustment.

[0125] In some embodiments, the adaptive parameters determined based on power loss variation information can be further corrected for deviations.

[0126] As an example, the deviation correction values ​​for the first-order moment parameters and the second-order moment parameters. and It can be represented as:

[0127] In some embodiments, the adaptive learning rate optimizer can calculate and output the voltage adjustment based on the updated adaptive parameters.

[0128] As an example, voltage regulation amount It can be represented as:

[0129] Where α is the learning rate, which is a fixed value; It is a small constant used to avoid the denominator being 0.

[0130] In some embodiments, to prevent the output voltage of the PFC circuit from jumping, the amount of voltage adjustment each time can be limited.

[0131] Therefore, as an optional implementation, the adaptive learning rate optimizer is pre-configured with a limit range for the voltage adjustment amount. Then, determining the voltage adjustment amount based on the updated adaptive parameters using the adaptive learning rate optimizer can include: determining the voltage adjustment amount based on the updated adaptive parameters and the limit range for the voltage adjustment amount, wherein the voltage adjustment amount is within the limit range.

[0132] By pre-configuring the voltage adjustment range in the adaptive learning rate optimizer, the adaptive learning rate optimizer can determine the voltage adjustment amount based on the range, avoiding voltage jumps caused by excessive voltage adjustment and improving the safety and reliability of air conditioning operation.

[0133] As an example, voltage regulation amount It can also be expressed as:

[0134] in, Indicates the maximum voltage adjustment amount. This indicates the minimum voltage adjustment amount.

[0135] It is understandable that if the output voltage of the power factor correction circuit is too high or too low, it may cause the operating voltage of the air conditioner to be too high or too low, thereby affecting the stability and safety of the air conditioner's operation.

[0136] Therefore, as an optional implementation, determining the target output voltage of the power factor correction circuit based on the current output voltage and voltage adjustment amount of the power factor correction circuit includes: obtaining a preset voltage range; and determining the target output voltage of the power factor correction circuit based on the current output voltage, voltage adjustment amount, and preset voltage range, wherein the target output voltage is within the preset voltage range.

[0137] By combining the preset voltage range, voltage adjustment amount, and current output voltage, the target output voltage can be determined, and the output voltage of the power factor correction circuit can be constrained within the preset voltage range. This avoids the impact on the operational stability and safety of the air conditioner due to the output voltage of the power factor correction circuit being too large or too small, thereby improving the operational stability and safety of the air conditioner.

[0138] In some embodiments, an output voltage can be determined first based on the voltage adjustment amount and the current output voltage. Then, it can be determined whether the output voltage is within a preset output voltage range. If it is, the output voltage can be directly determined as the target output voltage. If not, it needs to be constrained to the preset output voltage range.

[0139] As an example, the redefined output voltage U new It can be represented as: U new =U old +△u, where △u represents the voltage adjustment amount, U old This indicates the current output voltage.

[0140] Therefore, the target output voltage U can be expressed as: U = max(U min ,min(U max U new )).

[0141] In some embodiments, the adjustment of the output voltage of the power factor correction circuit can be achieved by adjusting the input voltage of the power factor correction circuit or the input voltage of related devices in the power factor correction circuit, etc. For details, please refer to the mature technologies in this field.

[0142] It is understood that the output voltage adjustment process of the power factor correction circuit in this embodiment is an iterative adjustment process. Through this iterative adjustment process, the total power loss of the air conditioner can be minimized.

[0143] Figure 2 This is a schematic diagram illustrating the control flow of an air conditioner according to an exemplary embodiment, such as... Figure 2 As shown, the control flow includes: The air conditioner is turned on and enters operating mode.

[0144] Obtain the current information of the air conditioner.

[0145] Based on the air conditioner's current information, check whether the air conditioner meets the current stability requirements.

[0146] If the air conditioner does not meet the current stability condition, return to the step of checking whether the air conditioner meets the current stability condition.

[0147] If the air conditioner meets the current stability condition, then calculate the power loss P1 of the air conditioner controller.

[0148] Next, adjust the output voltage of the PFC circuit, retest the air conditioner to ensure it meets the current stability condition, and then calculate the power loss P2 of the controller.

[0149] Calculate the difference ΔP between power losses P1 and P2, and determine whether ΔP is less than the preset difference.

[0150] If ΔP is less than the preset difference, the current compressor voltage is determined as the optimal compressor voltage, and the voltage adjustment mode can be exited. The compressor voltage is then controlled based on this optimal compressor voltage.

[0151] If ΔP does not meet the requirement of being less than the preset difference, the adaptive parameters in the adaptive learning rate optimizer are updated, and the voltage adjustment is calculated based on the updated adaptive parameters, and the voltage adjustment is limited to the preset range.

[0152] Then, within the preset voltage range, the output voltage of the PFC circuit is readjusted based on the voltage adjustment amount.

[0153] In this embodiment of the disclosure, by dynamically adjusting the output voltage of the PFC circuit, the power loss of the air conditioner is minimized, enabling the air conditioner to maintain efficient and low-energy operation under different load conditions, significantly reducing the operating energy consumption of the air conditioner, and enhancing its adaptability to different working environments.

[0154] In this embodiment, a real-time feedback mechanism is used to rapidly adjust the voltage based on changes in power loss, enhancing the response speed to load changes. Compared to related technologies, this allows the air conditioner to reach a new stable state in a shorter time.

[0155] In this embodiment of the disclosure, by using the momentum and adaptive learning rate characteristics of the Adam optimization algorithm, high stability is maintained during the adjustment process, avoiding fluctuations in the air conditioning system caused by frequent adjustments, so that the air conditioning can operate smoothly under various environmental conditions.
