Description

Technical Field

[0001] This specification relates to the field of heating, ventilation and air conditioning (HVAC), and in particular to a heating control method, device, storage medium, and electronic equipment. Background Technology

[0002] During the operation of air conditioning equipment, the electronic control module plays a crucial role in driving the operation of core components such as the compressor. It generates a significant amount of heat during high-power inverter operation. When the heat generated by the electronic control module exceeds its physical tolerance limit, it can easily cause permanent damage to internal components, leading to a system malfunction and shutdown. Currently, to prevent overheating of the electronic control module, the industry commonly uses methods such as setting a fixed AC current frequency limit or simply relating it to the external ambient temperature. When the current reaches a set threshold, the compressor's operating frequency is limited or reduced, thereby passively controlling the heat generated by the electronic control module.

[0003] However, this fixed current frequency limiting logic has significant limitations. The actual heating state of the electronic control module is not determined solely by the current, but is closely related to the overall real-time input power of the system. Since voltage fluctuations are constant in actual power grid operation, if the fixed current limiting threshold is set with reference to the rated voltage, then under high-voltage conditions, the same current often results in a larger actual input power. In this case, traditional current limiting logic cannot effectively suppress heating, easily leading to module overheating and damage. Conversely, if a conservative current limiting threshold is set with reference to high-voltage conditions for absolute safety, then under normal or low-voltage conditions, the system will prematurely trigger frequency limiting protection, severely restricting the optimal cooling or heating capacity output of the air conditioning equipment. Therefore, related technologies cannot effectively balance the safety protection of the electronic control module with the maximization of system capacity output. Summary of the Invention

[0004] This specification provides a method, apparatus, storage medium, and electronic device for controlling heat generation, which achieves dynamic frequency limiting control. While effectively preventing overheating of the electronic control module, it maximizes the system operating capacity of the air conditioning equipment. The technical solution is as follows: In a first aspect, embodiments of this specification provide a heat generation control method for adjusting the heat generated by an electronic control module in an air conditioning unit. The air conditioning unit is equipped with a compressor, and the electronic control module is used to drive the compressor to operate. The electronic control module is configured with a heat dissipation component. The method includes: Monitor the real-time input current and real-time input voltage of the air conditioning equipment to obtain the maximum power and maximum allowable current used for the heating limit of the electronic control module; Based on the real-time input voltage, the maximum power, and the preset power factor, the dynamic current threshold of the electronic control module under the current operating conditions is determined, and the comprehensive frequency limiting current is determined based on the dynamic current threshold and the maximum allowable current. The operating frequency of the compressor is adjusted based on the real-time input current and the comprehensive frequency limiting current to control the heat generation of the electronic control module.

[0005] Secondly, embodiments of this specification provide a heat dissipation control device for regulating the heat generated by an electronic control module in an air conditioning unit. The air conditioning unit includes a compressor, and the electronic control module drives the compressor. The electronic control module is equipped with heat dissipation components. The device includes: The monitoring module is used to monitor the real-time input current and real-time input voltage of the air conditioning equipment, and to obtain the maximum power and maximum allowable current for the heating limit of the electronic control module; The control module is used to determine the dynamic current threshold of the electronic control module under the current operating conditions based on the real-time input voltage, the maximum power and the preset power factor, and to determine the comprehensive frequency limiting current based on the dynamic current threshold and the maximum allowable current. The control module is used to adjust the operating frequency of the compressor based on the real-time input current and the comprehensive frequency limiting current, so as to control the heat generation of the electronic control module.

[0006] Thirdly, embodiments of this specification provide a computer storage medium storing a plurality of instructions adapted for loading by a processor and executing the above-described method steps.

[0007] Fourthly, this specification provides a computer program product storing at least one instruction adapted to be loaded by a processor and to execute the method steps of one or more embodiments of this specification.

[0008] Fifthly, this specification provides a computer program product storing at least one instruction adapted to be loaded by a processor and to execute the method steps of one or more embodiments of this specification.

[0009] Fifthly, embodiments of this specification provide an electronic device that may include: a processor and a memory; wherein the memory stores a computer program adapted to be loaded by the processor and to execute the above-described method steps.

[0010] The beneficial effects of the technical solutions provided in some embodiments of this specification include at least the following: In one or more embodiments of this specification, by real-time monitoring of the input voltage and current of the air conditioning equipment, a preset power factor of the electronic control module is introduced. The maximum power used for heat limitation is decoupled from the real-time input voltage to dynamically generate a current threshold adapted to the current power grid conditions. Simultaneously, this threshold is precisely determined by comparing it with the maximum allowable current at a purely physical level to obtain a comprehensive frequency-limiting current. Finally, based on the dynamic comparison between this comprehensive frequency-limiting current and the real-time input current, a closed-loop regulation of the compressor's operating frequency is implemented. This solves the technical problem that when air conditioning equipment relies on fixed current frequency-limiting logic for overheat protection, it cannot effectively balance the hardware safety of the electronic control module and the system's ultimate output capacity under fluctuating power grid voltage conditions (especially high-voltage conditions, which can easily lead to power overload and module burnout; and low / normal pressure conditions, which can easily lead to premature frequency limiting due to conservative thresholds). This represents a leap from traditional passive static current protection to active dynamic power protection. Through the aforementioned control logic, not only can frequency limiting intervention be triggered in advance based on the lower current threshold obtained through real-time decoupling when the grid voltage is high, effectively preventing thermal breakdown or permanent damage to internal power devices caused by excessive actual input power and severe heat accumulation in the electronic control module; simultaneously, under normal or low grid voltage conditions, the current limit can be automatically relaxed, completely avoiding the drawback of the system prematurely entering the protection state due to the overly conservative traditional fixed limits, thereby maximizing the cooling or heating efficiency of the air conditioning equipment within the safe thermal boundary. Ultimately, this solution ensures the absolute operational safety of the electronic control hardware in all weather conditions and across the entire voltage fluctuation range without increasing any additional expensive hardware costs, achieving a balance between long-term system reliability and the overall unit's extreme temperature control output capability.

Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this specification.

Those skilled in the art can understand the specific meaning of the above terms in this specification based on the specific circumstances. Furthermore, in the description of this specification, unless otherwise stated, "multiple" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0015] The present specification will now be described in detail with reference to specific embodiments.

[0016] In one embodiment, such as Figure 1As shown, a heat control method is proposed, which can be implemented using a computer program and can run on a heat control device based on the von Neumann architecture. This computer program can be integrated into an application or run as a standalone utility application. The heat control device can be an electronic device, such as an air conditioning unit or an electronic component (e.g., a microprocessor, electronic control unit, etc.) within the air conditioning unit, used to regulate the heat generated by the electronic control module in the air conditioning unit. The air conditioning unit is equipped with a compressor, and the electronic control module drives the compressor. The electronic control module is equipped with heat dissipation components.

[0017] For example, the following describes the architecture of a split-type frequency-divided air conditioning unit to aid understanding, such as... Figure 2 As shown, Figure 2 This is a schematic diagram of an example architecture for an air conditioning unit, mainly including an outdoor unit and an indoor unit interconnected by refrigerant piping. The outdoor unit contains a compressor 1, a four-way valve 2, an outdoor heat exchanger 3 (which may be a refrigerant heat exchanger), an outdoor fan 4 providing cooling airflow to the outdoor heat exchanger, a throttling device 5, and an electrical control module. Figure 2 (Not directly shown in the diagram). The indoor unit of the air conditioner is equipped with an indoor heat exchanger 7 and an indoor fan 8 that provides heat exchange airflow to the indoor environment.

[0018] In the refrigerant circulation system, to prevent the electronic control module from overheating during high-power operation, a dedicated heat dissipation component (specifically, a refrigerant radiator 6 in this embodiment) can be installed inside the outdoor unit of the air conditioner. The refrigerant radiator 6 is connected in series in the refrigerant pipeline downstream of the throttling component 5, and uses the low-temperature, low-pressure liquid (or gas-liquid two-phase) refrigerant flowing through it to absorb and carry away the heat generated by the electronic control module during operation.

[0019] It is particularly important to note the following regarding the electronic control module described in this invention: exist Figure 2 In the illustrated hardware topology, the "INV" label next to number 1 (compressor) represents the final inverter output execution terminal of the electronic control module. Those skilled in the art should understand that the electronic control module, as a complete AC / DC power conversion hub, physically consists of the refrigerant radiator 6 tightly attached to its heating substrate; electrically, it internally cascades a rectifier filter circuit, a power factor correction (PFC) boost circuit, and an inverter drive circuit (INV).

[0020] For example, the following is a schematic diagram of an energy conversion scenario for an electronic control module, such as... Figure 3 As shown, in Figure 3 The diagram shows the specific energy conversion path of the electronic control module as follows: First, the rectifier and filter circuit of the electronic control module receives the primary AC power (such as 220V / 50Hz mains power) from the external power grid and rectifies it into a smooth primary DC power (about 310V). The "real-time input voltage" and "real-time input current" sampled in the control method of the present invention can be the power grid side input terminal located at this stage of the circuit. Secondly, the power factor correction (PFC) boost circuit further boosts the primary DC voltage to a higher stable DC voltage (around 380V) and corrects the current waveform in the process. This also relates to the hardware physical source of the preset "power factor (PF)" involved in one or more embodiments of this specification. Finally, the inverter drive circuit (INV) uses its internal power semiconductor switching devices (such as IGBT modules) to convert high-voltage DC power into three-phase AC power with stepless adjustment of both frequency and voltage, which is used to directly drive the compressor 1. The conduction and switching heat losses generated during the above multi-stage power conversion process are the "heat" that this invention needs to control and dissipate, which is handled by a refrigerant radiator 6 (not limited to one type of refrigerant heat dissipation; the above is only for ease of understanding).

[0021] Specifically, the heat control method includes: S102: Monitor the real-time input current and real-time input voltage of the air conditioning equipment, and obtain the maximum power and maximum allowable current used for the heating limit of the electronic control module; In practical implementation, the electrical control module of the air conditioner outdoor unit is equipped with a high-precision voltage transformer (or voltage sampling circuit) and a current transformer (or shunt sampling circuit). When the air conditioner is in cooling or heating operation, it monitors the real-time input current and real-time input voltage at a preset sampling period through an analog-to-digital converter (A / D interface). For example, it can detect the real-time AC input voltage (Vac) and real-time AC input current Iac from the power grid side. At the same time, it reads preset safety reference parameters from its internal memory, namely the maximum power (Watt_max) used to limit the heating of the electrical control module and the maximum allowable current (Iac_max) limited by the physical limits of the hardware.

[0022] The maximum power (Watt_max) represents the limit of electrical power that the electronic control module can operate stably for a long time without thermal breakdown under the design heat dissipation capacity of the currently configured heat dissipation components (such as refrigerant heat sinks or air-cooled heat dissipation components). In some embodiments, this value can be a factory-fixed static safety value or a related calculated value that is dynamically updated in real time according to the external ambient temperature or the state of the heat dissipation medium.

[0023] The maximum allowable current (Iac_max) is usually a safety limit set to prevent cables from melting or devices from burning out due to instantaneous overcurrent.

[0024] In one feasible implementation, monitoring the real-time input current of the air conditioning equipment can be achieved in the following way: Optionally, the primary AC current on the grid side of the air conditioning equipment can be collected as the real-time input current; Primary AC current: refers to the total AC current that the air conditioning equipment directly draws from the external mains power grid at the energy input source. This node is located before all power conversions (such as rectification, boost, and inversion) occur within the electrical control module, representing the most basic overall load input of the air conditioning equipment system.

[0025] In a schematic representation, a direct measurement method can be used. On the mains input live wire (L line) or neutral wire (N line) circuit of the air conditioning unit, a hardware sampling circuit, such as a high-precision current transformer or a high-power shunt resistor connected in series, is installed. When the air conditioning unit is operating, this hardware sampling circuit senses the passing AC mains current in real time and converts it into a low-voltage analog signal. This signal is directly read through its built-in analog-to-digital converter (A / D module), filtered, and directly used as the "real-time input current." The advantage of this process is that the acquired data is intuitive, has no delay, and includes the entire current load of the air conditioning system (including indoor and outdoor fans, electrical control losses, etc.), resulting in high control accuracy.

[0026] Optionally, the secondary phase current output by the electronic control module to the compressor drive terminal can be collected as the real-time input current.

[0027] Secondary phase current: refers to the three-phase AC drive current that is finally output to the stator winding of the compressor motor after the grid power has passed through the rectification, filtering, power factor correction and high-frequency inversion inside the electronic control module. This node is located at the very end of the energy transmission link.

[0028] In illustrative terms, in related technologies, to achieve vector control of the compressor, the electronic control module of a variable frequency air conditioner typically includes a sampling resistor in the lower arm of the inverter bridge for detecting the secondary phase current. This secondary phase current can be directly read, along with known internal parameters such as the real-time operating frequency of the inverter output, the bus DC voltage, and the pulse width modulation duty cycle. Based on the law of conservation of energy (i.e., the input power minus the electronic control conversion losses is approximately equal to the output power), an internal conversion algorithm is executed to reverse-convert the secondary phase current into an equivalent input current on the grid side, and this converted equivalent value is used as the "real-time input current." This process, without increasing any additional hardware BOM cost, cleverly achieves accurate estimation of the total input power load through underlying algorithm reuse.

[0029] S104: Based on the real-time input voltage, the maximum power, and the preset power factor, determine the dynamic current threshold of the electronic control module under the current operating conditions, and determine the comprehensive frequency limiting current based on the dynamic current threshold and the maximum allowable current. The preset power factor (PF) refers to the cosine value of the phase difference between voltage and current in an AC circuit. It is mainly determined by the hardware electrical characteristics and software compensation algorithm of the power factor correction circuit configured inside the electronic control module. It is usually represented as a fixed constant stored in the microprocessor or a piecewise fitting coefficient that varies with the load rate.

[0030] Dynamic current threshold: This refers to the maximum AC current value theoretically allowed to pass through under the premise of meeting the above maximum power limits, as specified in this specification. This threshold is not fixed but changes adaptively and decoupled in real time with fluctuations in the mains voltage.

[0031] Comprehensive frequency limiting current: refers to the current criterion used as the basis for frequency limiting intervention, which takes into account both the system's thermodynamic heating constraints (i.e., power constraints) and the purely electrical hardware overcurrent constraints (i.e., current constraints).

[0032] In one feasible implementation, a multi-dimensional data mapping matrix (such as a two-dimensional lookup table matrix) can be pre-set. The real-time input voltage and the preset power factor are used as the row and column index parameters of the matrix. The corresponding current conversion coefficient is obtained by lookup table matching. The maximum power is multiplied by the current conversion coefficient to obtain the dynamic current threshold.

[0033] Furthermore, to prevent frequent fluctuations in the calculated dynamic current threshold caused by transient voltage spikes in the grid when determining the final comprehensive frequency-limiting current, a first-order hysteresis filtering algorithm can be introduced before comparison. The smoothed dynamic current threshold is compared with the maximum allowable current. If the smoothed dynamic current threshold is less than the maximum allowable current, the comprehensive frequency-limiting current is determined to be the smoothed dynamic current threshold; if the smoothed dynamic current threshold is greater than or equal to the maximum allowable current, the comprehensive frequency-limiting current is determined to be the maximum allowable current. This implementation method significantly reduces the computational load and improves anti-interference robustness while ensuring protection accuracy.

[0034] Optionally, the specific execution of step S104, which involves determining the dynamic current threshold of the electronic control module under the current operating conditions based on the real-time input voltage, the maximum power, and the preset power factor, and determining the comprehensive frequency limiting current based on the dynamic current threshold and the maximum allowable current, can be performed using the following method: The dynamic current threshold is obtained by dividing the maximum power by the product of the real-time input voltage and the power factor. The smaller value between the dynamic current threshold and the maximum allowable current is determined as the comprehensive frequency limiting current.

[0035] In this embodiment, the maximum power read is divided by the product of the real-time input voltage Vac and the preset power factor PF to calculate the dynamic current threshold Watt_max / (Vac*PF) of the electronic control module under the current operating condition. This dynamic current threshold is then compared in real time with the aforementioned maximum allowable current, and the smaller of the two values ​​is selected as the final comprehensive frequency-limiting current Iac_Lmt. This can be expressed by the following formula: Iac_Lmt=min(Watt_max / (Vac*PF),Iac_lmt) Through the above calculations, it can be ensured that under any grid voltage fluctuation conditions, the calculated comprehensive frequency limiting current can strictly clamp the total input power of the electronic control module within the safe limit allowed by the heat dissipation capacity, realizing the leap from passive static current limiting to active dynamic voltage and current limiting.

[0036] S106: Adjust the operating frequency of the compressor based on the real-time input current and the comprehensive frequency limiting current to control the heat generation of the electronic control module.

[0037] This is illustrative of calculating the difference between the real-time input current and the comprehensive frequency-limiting current within the control cycle.

[0038] When the real-time input current exceeds the comprehensive frequency limiting current, the frequency reduction or frequency increase is not immediately executed. Instead, the internal integrator is activated to integrate the excess current value over time and calculate the current thermal load accumulation in real time.

[0039] The cumulative integral of the heat load is continuously compared with the preset heat capacity trigger threshold. If the cumulative integral of the heat load does not reach the heat capacity trigger threshold, it means that the overcurrent at this time is only a short-term transient phenomenon. The physical heat capacity of the electronic control module is sufficient to absorb this part of the heat and will not cause the temperature rise to exceed the standard. The electronic equipment maintains the current operating frequency of the compressor unchanged. If the system continues to be overloaded, causing the cumulative integral of the heat load to rise continuously and reach or exceed the heat capacity trigger threshold, the electronic device determines that a substantial heat threat has been formed, and then deducts one frequency reduction penalty step from the current compressor operating frequency to forcibly reduce the heat generation.

[0040] Correspondingly, when the real-time input current after frequency reduction is less than the comprehensive frequency limiting current, the integrator begins to perform negative integration (i.e., simulating the cooling process of heat loss over time) until the integral value is cleared to zero, and the electronic equipment is completely deactivated. This implementation process greatly improves the air conditioning equipment's anti-disturbance capability under extreme operating conditions and avoids unnecessary frequency fluctuations.

[0041] In one or more embodiments of this specification, by real-time monitoring of the input voltage and current of the air conditioning equipment, a preset power factor of the electronic control module is introduced. The maximum power used for heat limitation is decoupled from the real-time input voltage to dynamically generate a current threshold adapted to the current power grid conditions. Simultaneously, this threshold is precisely determined by comparing it with the maximum permissible current at a purely physical level to obtain a comprehensive frequency-limiting current. Finally, based on the dynamic comparison between this comprehensive frequency-limiting current and the real-time input current, a closed-loop regulation of the compressor's operating frequency is implemented. This solves the technical problem that when air conditioning equipment relies on fixed current frequency-limiting logic for overheat protection, it cannot effectively balance the hardware safety of the electronic control module and the system's ultimate output capacity under fluctuating power grid voltage conditions (especially under high-voltage conditions, which can easily lead to power overload and module burnout; under low / normal pressure conditions, it can easily lead to premature frequency limiting due to conservative thresholds). This represents a leap from traditional passive static current protection to active dynamic power protection. Through the aforementioned control logic, not only can frequency limiting intervention be triggered in advance based on the lower current threshold obtained through real-time decoupling when the grid voltage is high, effectively preventing thermal breakdown or permanent damage to internal power devices caused by excessive actual input power and severe heat accumulation in the electronic control module; simultaneously, under normal or low grid voltage conditions, the current limit can be automatically relaxed, completely avoiding the drawback of the system prematurely entering the protection state due to the overly conservative traditional fixed limits, thereby maximizing the cooling or heating efficiency of the air conditioning equipment within the safe thermal boundary. Ultimately, this solution ensures the absolute operational safety of the electronic control hardware in all weather conditions and across the entire voltage fluctuation range without increasing any additional expensive hardware costs, achieving a balance between long-term system reliability and the overall unit's extreme temperature control output capability.

[0042] Optional, such as Figure 4 As shown, Figure 4 This is a flowchart illustrating compressor frequency regulation. Specifically, the compressor's operating frequency is adjusted based on the comparison between the real-time input current Iac and the comprehensive frequency-limiting current Iac_Lmt. The following method can be used as a reference: S202: Obtain the first bias parameter and the second bias parameter; The first bias parameter (denoted as C) and the second bias parameter (denoted as A) are two internally preset safety margin constants used to define different levels of safety warning intervals before reaching the absolute frequency limiting threshold (i.e., the comprehensive frequency limiting current Iac_Lmt). In engineering logic, the first bias parameter is usually greater than the second bias parameter (both are greater than 0) to ensure that the primary warning of prohibiting frequency increase is triggered first, followed by the advanced intervention of forced frequency reduction.

[0043] S204: When the real-time input current is greater than or equal to the difference between the comprehensive frequency limiting current and the first bias parameter, the compressor frequency increase is prohibited; The difference between the integrated frequency-limiting current and the first bias parameter can be denoted as Iac_Lmt-C, to construct the first line of defense; "Disable compressor frequency increase" means locking the upper limit of the target operating frequency currently output to the compressor. In this state, any frequency increase requests due to insufficient room temperature are blocked, but normal frequency reduction is allowed according to temperature control requirements. This can be regarded as a pressure-maintaining control strategy that only reduces the frequency and does not increase it.

[0044] S206: When the real-time input current is greater than or equal to the difference between the comprehensive frequency limiting current and the second bias parameter, the compressor frequency reduction is executed.

[0045] The difference between the combined frequency-limiting current and the second bias parameter can be denoted as Iac_Lmt-A, to construct a second line of defense; The compressor frequency reduction refers to forcibly taking over the inverter control, which can ignore the current indoor temperature control needs and actively and forcibly reduce the actual operating frequency of the compressor at a preset rate (such as 1Hz / s) in order to sacrifice some cooling / heating output to achieve safe cooling of the electronic control module.

[0046] This specification describes a technological upgrade achieved through the refined control steps described above, transitioning from a single rigid protection mechanism to a multi-level flexible system. As the system's heat load gradually increases, the control logic prioritizes triggering the outer frequency-prevention defense for early warning and load maintenance, thus avoiding unnecessary significant frequency reductions. Only when the heat load continues to deteriorate and triggers the inner defense will the system decisively execute forced frequency reduction to precisely and quickly curb thermal runaway. This ensures the mechanical smoothness and long service life of the compressor, and, while guaranteeing that the electronic control module will never suffer thermal breakdown damage, minimizes interference from safety protection interventions on the normal cooling or heating capacity output of the air conditioner. It balances the ultimate thermal safety of the underlying hardware with the ultimate efficiency of the entire unit and user comfort.

[0047] Optionally, after performing the steps described above to prevent the compressor from increasing its frequency or to reduce its frequency, the following implementation method can be referred to: S302: Obtain the third, fourth, and fifth bias parameters; The third bias parameter (which can be denoted as B) and the fourth bias parameter (which can be denoted as D) refer to the preset state recovery tolerance constants, used to construct the lower half of the hysteresis loop. Optionally, the fourth bias parameter is greater than the third bias parameter and both are greater than 0, to ensure that when the current drops, the frequency reduction is stopped first (voltage holding observation), and the complete unlocking is triggered only after the current returns to a deeper safe zone.

[0048] The fifth bias parameter (which can be denoted as E) refers to the preset limit disaster recovery bias constant. This parameter, when added to the comprehensive frequency limiting current, constitutes an absolute shutdown red line that surpasses all conventional frequency conversion regulation algorithms.

[0049] S304: When the real-time input current is less than the difference between the comprehensive frequency limiting current and the third bias parameter, the step of reducing the compressor frequency is terminated. The difference between the integrated frequency limiting current and the third bias parameter can be denoted as Iac_Lmt-B; The compressor frequency reduction instruction is canceled, and the compressor stops reducing the frequency. However, its upper limit frequency still exists. At this time, it can be regarded as being in an intermediate "wait and see" period.

[0050] S306: When the real-time input current is less than the difference between the comprehensive frequency limiting current and the fourth bias parameter, the step of prohibiting the compressor from increasing its frequency is lifted; The difference between the integrated frequency limiting current and the fourth bias parameter can be denoted as Iac_Lmt-D; The execution of the prohibition on compressor frequency increase is lifted, which completely releases the forced safety control over the compressor inverter module. For example, the compressor's operating frequency is returned to the normal indoor ambient temperature PID loop for free adjustment.

[0051] S308: When the real-time input current is greater than or equal to the sum of the comprehensive frequency limiting current and the fifth bias parameter, execute the system protection shutdown procedure.

[0052] The sum of the integrated frequency limiting current and the fifth bias parameter can be denoted as Iac_Lmt + E. System protection shutdown refers to immediately blocking all pulse width modulation (PWM) signals output to the inverter drive module (INV), cutting off the compressor's power source from the physical circuitry to prevent catastrophic thermal damage to the electronic control module.

[0053] Exemplarily, when the system is already in the frequency-down intervention state, the microprocessor continuously executes the difference comparison logic at a high frequency: When the heat generation of the system decreases due to frequency down, the real-time operating current drops back and satisfies Iac < Iac_Lmt - B (execute S304), it is determined that the frequency-down measure has effectively curbed the thermal runaway, and immediately execute "解除强制压缩机降频" (Release forced compressor frequency down); If the heat dissipation condition further improves, the real-time operating current continues to drop back and satisfies Iac < Iac_Lmt - D (execute S306), it is determined that the system has returned to the high safety margin area, execute "解除禁止压缩机升频" (Release the prohibition of compressor frequency up), and resume the conventional temperature control regulation. At the same time, a shutdown interruption runs in parallel in the background: If an extremely恶劣工况 (severe working condition) causes the current to soar out of control, when it satisfies Iac ≥ Iac_Lmt + E (execute S308), bypass all mitigation adjustment means and trigger the "system protection shutdown" instruction.

[0054] Exemplarily, as Figure 5 shown, Figure 5 is a schematic diagram of compressor frequency control. In the figure, the vertical coordinate represents the real-time input current Iac of the air-conditioning equipment, and Iac_Lmt is the comprehensive frequency-limiting current baseline calculated by the system's dynamic decoupling. The system sets a series of offset parameters (the fifth offset parameter E, the second offset parameter A, the third offset parameter B, the first offset parameter C, the fourth offset parameter D), and demarcates different levels of safety defenses above and below the baseline. From the physical threshold levels shown in the figure, it can be seen that the engineering magnitude relationship of the absolute values of each offset parameter satisfies: A < B < C < D.

[0055] Combined with the foregoing control steps, the specific evolution process of this control logic diagram is as follows: I. Current rising period (corresponding to Figure 5 the upward arrow on the left side in and execute S202 - S206) When the load of the air-conditioning system gradually increases and the real-time input current Iac continuously climbs along the left arrow trajectory, the system sequentially triggers the warning and intervention mechanisms: Figure 5 1) Touch the primary defense line (corresponding to execute S204): When the current rises and touches the Iac_Lmt - C threshold line, it is determined that the heat generation of the system enters the warning area, and immediately execute the "禁止升频" (Prohibit frequency up) action. Figure 5 The flat section on the right side of this threshold line in

[0056] 2) Touch the advanced defense line (corresponding to execute S206): If the load continues to deteriorate in the frequency-up prohibited state and the current continues to climb and touches the Iac_Lmt - A threshold line, it is determined that there is a risk of thermal breakdown, and immediately execute the "强制降频" (Forced frequency down) action. At this time, the compressor speed is forcibly lowered, and the heat generation power of the electronic control module is reduced from the source.

[0057] It should be noted that the Chinese term "解除强制压缩机降频" and "解除禁止压缩机升频" are left in Chinese as there is no clear indication of their exact English equivalents in the context. You may need to provide more context or clarify these terms for a more accurate translation. Also, "恶劣工况" is translated as "severe working condition" as a placeholder, which may need to be adjusted according to the actual situation.II. Current Fallback Period (corresponding to the downward arrow on the right and execution of S302-S306): After forced frequency reduction, the heat generated by the electronic control module decreases, and the real-time input current (Iac) begins to fall back along the trajectory of the arrow on the right. To prevent frequent frequency increase / decrease jumps (i.e., system oscillation) near the threshold line, the embodiment in this specification adopts a hysteresis design of "separation of trigger line and recovery line": Release of forced frequency reduction (corresponding to execution of S304): When the current falls back to the original trigger line (Iac_Lmt-A), the intervention is not immediately released, but needs to continue to fall back to the lower I_ac_Lmt-B threshold line (at this time, a hysteresis buffer band of size BA is formed). It is determined that thermal runaway has been effectively contained. At this time, frequency reduction stops, and the system returns to the "prohibited frequency increase" voltage holding and observation state. Completely restore frequency boost (corresponding to execution S306): If the current drops further, it must also cross the original warning line (Iac_Lmt-C) and continue to fall back to the lowest threshold line I_ac_Lmt-D (forming a second-level hysteresis buffer band of size DC) before the microprocessor determines that the system has completely retreated to the safe zone, executes "restore frequency boost" (i.e., remove the prohibition on frequency boost), and returns control to the regular temperature control logic.

[0058] III. Limit Protection (corresponding to the top horizontal line and S308) Figure 5 The highest horizontal line in the middle is the absolute safety red line. Under any operating condition, if a sudden extreme fault (such as the sudden stop of the external fan) causes the current to surge uncontrollably, once it touches the Iac_Lmt+E threshold line (corresponding to the execution of S308), it will bypass all graded frequency regulation methods and directly trigger "system shutdown", cutting off the inverter drive output to ensure the absolute physical safety of the hardware.

[0059] Optionally, the process of obtaining the preset maximum power limit for the heating of the electronic control module can also be performed in the following ways: Obtain the current real-time heat dissipation capability parameters of the heat dissipation component, and update the value of the maximum power based on the real-time heat dissipation capability parameters.

[0060] in: Real-time heat dissipation capability parameters refer to physical variables that characterize the efficiency or potential of the current air conditioner outdoor unit's heat dissipation components (such as refrigerant radiators or air-cooled heat dissipation components) in dissipating the heat generated by the electronic control module to the external environment. This parameter can be a single environmental parameter that is directly measured (such as outdoor ambient temperature), or it can be a system internal circulation status parameter (such as refrigerant high pressure, refrigerant pipe temperature, or outdoor fan speed).

[0061] Updating the maximum power value means breaking the factory-fixed single power limit and adjusting the maximum power Watt_max baseline value in step S104 upwards or downwards in real time based on the current "heat dissipation capacity". The core logic is: when the heat dissipation capacity deteriorates, the maximum allowable heat dissipation power is actively reduced; when the heat dissipation capacity is sufficient, the maximum allowable heat dissipation power is actively increased.

[0062] In one feasible implementation, a highly reliable ambient temperature feedforward control is employed. Whether using air cooling or refrigerant cooling, the ultimate heat sink is the outdoor ambient air; therefore, the outdoor ambient temperature To is the most critical variable determining heat dissipation capacity. An outdoor ambient temperature sensor collects the current outdoor ambient temperature in real time as the "real-time heat dissipation capacity parameter," pre-programmed with a mapping curve or one-dimensional discrete lookup table matrix showing a negative correlation between ambient temperature and maximum allowable power. When the collected outdoor ambient temperature increases (indicating a decrease in heat exchange temperature difference and reduced heat dissipation capacity), a smaller power setpoint is obtained through a lookup table or curve, and this setpoint is used to update the current maximum power Watt_max. Conversely, when the outdoor ambient temperature decreases (indicating a larger heat exchange temperature difference and increased heat dissipation capacity), a larger power setpoint is obtained through a lookup table or curve, and this setpoint is used to update the maximum power Watt_max. This process consumes minimal computational power and effectively prevents thermal breakdown under extreme high temperatures.

[0063] Optionally, the air conditioning equipment further includes refrigerant piping and a throttling device, and the heat dissipation component is a refrigerant radiator connected to the refrigerant piping downstream of the throttling device (see reference). Figure 2 Specifically, the process of obtaining the current real-time heat dissipation capacity parameters of the heat dissipation component and updating the maximum power value based on the real-time heat dissipation capacity parameters can be performed in the following manner: S402: Monitor the refrigerant cooling temperature and / or refrigerant mass flow rate through the refrigerant radiator; A refrigerant radiator is a thermally conductive aluminum / copper component with internal microchannels or coils. Its physical mounting surface is in close contact with the heat-generating power devices (such as IGBT chips) of the electronic control module. Its two ends are connected in series or parallel downstream to the throttling device (such as an electronic expansion valve) of the air conditioning system, using the low-temperature, low-pressure liquid or gas-liquid two-phase refrigerant generated after throttling and pressure reduction to absorb the heat from the electronic control module.

[0064] The refrigerant cooling temperature refers to the real-time physical temperature of the refrigerant flowing through the refrigerant radiator. The lower this temperature, the greater the heat exchange temperature difference between the radiator and the electronic control module, indicating that more heat can be removed per unit time.

[0065] Refrigerant mass flow rate refers to the physical mass of refrigerant flowing through the cross-section of the refrigerant radiator per unit time. Given a constant specific enthalpy difference, a higher refrigerant mass flow rate indicates a higher upper limit to the overall heat dissipation capacity of the system.

[0066] S404: Update the value of the maximum power based on the refrigerant cooling temperature and / or refrigerant mass flow rate.

[0067] Updating the value of the maximum power refers to dynamically rewriting the Watt_max variable value used for calculating the maximum power in the system memory based on the aforementioned refrigerant cooling temperature and / or refrigerant mass flow rate.

[0068] In one feasible implementation, when a decrease in the refrigerant cooling temperature and / or an increase in the refrigerant mass flow rate are detected, it is determined that the heat dissipation capacity of the refrigerant radiator has increased, and the maximum power value is increased; when an increase in the refrigerant cooling temperature and / or a decrease in the refrigerant mass flow rate are detected, it is determined that the heat dissipation capacity of the refrigerant radiator has decreased, and the maximum power value is decreased. For example, by reusing existing conventional sensors in the system to construct the underlying thermodynamic state equation, the real-time refrigerant mass flow rate can be accurately calculated, and the maximum allowable power of the electronic control module can be coupled in the end. Specifically, during any control cycle of the air conditioning equipment, the system's existing sensor network and the underlying interface of the variable frequency drive are used to synchronously collect the compressor's real-time operating frequency, the system high-pressure side pressure obtained by the exhaust side pressure sensor, the system low-pressure side pressure obtained by the return gas side pressure sensor, the refrigerant return gas temperature obtained by the suction port temperature sensor, and the refrigerant cooling temperature obtained by the temperature sensor attached to the surface of the refrigerant radiator. Based on the acquired system low-pressure side pressure and refrigerant return gas temperature, combined with a pre-stored refrigerant property parameter table, the refrigerant suction density entering the compressor suction port is calculated by looking up the table or polynomial fitting; at the same time, the high-low pressure ratio of the current system high-pressure side pressure and system low-pressure side pressure is calculated, and it is substituted into a pre-calibrated compressor volumetric efficiency fitting function to calculate the actual volumetric efficiency under the current operating condition. Based on the above derived parameters, using the pre-stored theoretical cylinder displacement of the compressor, the transient refrigerant mass flow rate flowing through the refrigerant radiator is obtained by multiplying the actual volumetric efficiency, theoretical cylinder displacement, real-time compressor operating frequency, and refrigerant suction density. After successfully resolving the transient refrigerant mass flow rate and directly acquiring the refrigerant cooling temperature, a thermoelectric coupling calculation stage is performed. This stage utilizes the internally preset power semiconductor device limit safe junction temperature and the thermal resistance inverse proportionality coefficient K, which characterizes the geometry of the heat dissipation component and the inherent physical properties of the thermally conductive material. Based on Newton's law of cooling and the convective heat transfer physical model, the thermal resistance inverse proportionality coefficient K, the calculated transient refrigerant mass flow rate m, and the heat transfer temperature difference between the limit safe junction temperature T_limit and the refrigerant cooling temperature T_ref are multiplied (i.e., the calculation formula Watt_max = K * m * (T_limit - T_ref)) to calculate the absolute limit heat transfer power Watt_max that can be carried away under the current refrigerant condition. Finally, the calculated value is directly assigned and updated to the maximum power value of the current control cycle.

[0069] This specification describes the implementation of cross-domain dynamic adaptive coupling between the underlying physical thermodynamic system and the upper-level variable frequency electrical control. By using refrigerant temperature and mass flow rate as feedforward adjustment parameters, the system can proactively and significantly increase the maximum allowable power limit of the electronic control module under superior heat dissipation conditions such as abundant refrigerant circulation and low cooling temperature. This completely unlocks the high-frequency operation of the compressor, maximizing the release of the air conditioning equipment's extreme rapid cooling or heating potential. Conversely, under conditions such as extreme weather or refrigerant leakage leading to a sharp drop in actual heat dissipation capacity, the system can sensitively detect underlying thermodynamic anomalies and quickly tighten the maximum power reference, allowing for earlier and more precise frequency reduction protection. This innovative thermoelectric coupling mechanism, without increasing additional high hardware costs, enables full-speed output under good heat dissipation conditions and precise self-protection under poor heat dissipation conditions.

[0070] Optionally, the heat dissipation component is an air-cooled heat dissipation assembly configured for the electronic control module (which can be installed around the electronic control module inside the outdoor unit of the air conditioner); specifically, the process of obtaining the current real-time heat dissipation capacity parameters of the heat dissipation component and updating the value of the maximum power based on the real-time heat dissipation capacity parameters can be performed in the following manner: Monitor the real-time ambient temperature of the environment where the air conditioning equipment is located, and update the value of the maximum power according to the real-time ambient temperature.

[0071] in: Air-cooled heat dissipation components refer to high thermal conductivity metal heat dissipation fins set on the back (or periphery) of the heating substrate of the electronic control module. They rely on the negative pressure airflow generated by the main shaft fan of the outdoor unit of the air conditioner, or on the forced convection by a specially configured independent micro fan, to directly dissipate the heat generated by the electronic control module into the surrounding air, which is a purely physical heat dissipation structure.

[0072] Real-time ambient temperature refers to the absolute temperature of the outdoor ambient air, which is collected in real time by temperature sensors (such as ambient temperature sensors) installed at the air inlet of the outdoor unit of the air conditioner or in the surrounding environment.

[0073] In one feasible implementation, when the real-time ambient temperature is detected to decrease, it is determined that the heat dissipation capacity of the air-cooled heat dissipation component is enhanced, and the value of the maximum power is increased; when the real-time ambient temperature is detected to increase, it is determined that the heat dissipation capacity of the air-cooled heat dissipation component is weakened, and the value of the maximum power is decreased.

[0074] In one feasible implementation, a forced convection thermodynamic state equation is constructed by reusing the ambient temperature sensing element and the speed feedback signal from the fan's underlying layer. This allows for the accurate calculation of the transient true heat dissipation limit of the air-cooled heat dissipation component, and the dynamic update of the maximum allowable power accordingly. Specifically, during any control cycle of the air conditioning equipment operation, the real-time ambient temperature To, obtained from the ambient temperature sensor located at the air inlet of the outdoor unit, and the real-time operating speed N_fan of the outdoor fan are simultaneously collected through the system's existing sensor network and motor drive interface. After obtaining these parameters, thermodynamic state calculations are performed, calling the pre-stored limit safe junction temperature T_limit of the power semiconductor device in the electronic control module and the inherent structural wind resistance coefficient C_str of the air-cooled heat dissipation component. Subsequently, a subtraction operation is performed based on the real-time ambient temperature and the limit safe junction temperature to calculate the theoretical maximum heat transfer temperature difference DT = T_limit - To of the current system; simultaneously, the real-time operating speed of the outdoor fan is substituted into the pre-calibrated speed-airflow mapping polynomial to calculate the forced convection heat transfer coefficient compensation factor h_wind under the current operating condition. Next, using the physical model of Newton's law of cooling, the combined structural drag coefficient, forced convection heat transfer coefficient compensation factor, and theoretical maximum heat transfer temperature difference are multiplied together using the formula Watt_max = C_str*h_wind*(T_limit- T_o) to accurately reconstruct the absolute limit heat power that the air-cooled heat dissipation component can dissipate under the current transient state. After completing the dual-parameter coupled calculation, to prevent frequent jumps in calculation results caused by brief mechanical fluctuations in the outdoor fan speed due to backdrafts from outdoor gusts, the absolute limit heat power calculated over multiple consecutive control cycles is smoothed and filtered. Finally, the filtered final smoothed value is directly assigned and updated to the maximum power Watt_max value of the current control cycle.

[0075] In this specification, the above method is used to realize the direct mapping and update process based on a single environmental temperature variable, and realize the rapid adaptive response of the heating safety boundary of the electronic control module to external extreme climate changes, enabling it to respond quickly to changes in external extreme climate.
