[0077] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0078] The inventors discovered through research that traditional control strategies in related technologies typically employ unified scheduling or load balancing mechanisms, which cannot effectively distinguish the priority of ice-making tasks from other temperature zone control tasks, resulting in a decline in user experience, especially under high-load conditions.

[0079] In view of at least one of the above-mentioned technical problems, there is an urgent need for a novel control mechanism that can ensure the continuity of the ice-making process in a multi-system parallel operation environment. This disclosure provides a refrigerator and its ice-making control method, controller, storage medium, and program product. The disclosure is described below through specific embodiments.

[0080] Figure 1 This is a schematic diagram of some embodiments of the refrigerator ice-making control method disclosed herein. Figure 1 The embodiments can be executed by the refrigerator or controller of this disclosure. For example... Figure 1 As shown, Figure 1 The method in the embodiment may include step 100.

[0081] In step 100, during refrigerator operation, the priority of the ice-making system is set to the highest.

[0082] In step 200, when both the ice-making system and the temperature zone control system request cooling output simultaneously, cooling is preferentially delivered to the ice-making system to ensure that the ice-making system completes the current ice-making cycle. The refrigerator includes the ice-making system and the temperature zone control system, and the temperature zone control system includes at least one of a freezing system, a refrigeration system, and a variable temperature system.

[0083] Figure 2 These are schematic diagrams illustrating some embodiments of the refrigerator disclosed herein. Figure 2 As shown, the present disclosure may include a temperature zone control system 11, an ice-making system 12, and a controller 13.

[0084] The embodiments disclosed above establish a control mechanism with the highest priority for the ice-making system, thereby ensuring that the ice-making process is not interrupted when multiple systems are working simultaneously, significantly reducing the ice-making interruption rate and improving ice-making efficiency.

[0085] The embodiments of this disclosure prioritize the ice-making system as the highest priority among all systems, ensuring that any other temperature zone (such as refrigeration, variable temperature, or freezing) cannot interrupt or reduce the load on the ice-making system. When multiple systems simultaneously request cooling output, these embodiments prioritize ensuring the ice-making system completes its current ice-making cycle.

[0086] The ice-making system of the above embodiments of this disclosure has the highest and inalienable control priority in the parallel operation of four systems, and other systems shall not actively interrupt or reduce the load on the ice-making system.

[0087] The above embodiments of this disclosure provide a method for prioritizing ice-making in parallel operation of multiple systems, which can ensure the continuity of the ice-making process in a multi-system parallel operation environment.

[0088] In the above embodiments of this disclosure, when both the ice-making system and the temperature zone control system request cooling output simultaneously, the ice-making system can be prioritized to complete the current ice-making cycle, thereby significantly reducing the ice-making interruption rate and improving ice-making efficiency.

[0089] In some embodiments of this disclosure, step 200, the step of preferentially supplying cold energy to the ice-making system, may include: preferentially supplying cold energy to the ice-making compartment evaporator of the ice-making system, wherein the refrigerator includes an ice-making system, a freezing system, a refrigeration system, and a variable-temperature system, the freezing system includes a freezing compartment evaporator, the refrigeration system includes a refrigeration compartment evaporator, the variable-temperature system includes a variable-temperature compartment evaporator, the ice-making system includes an ice-making compartment evaporator, and the ice-making compartment evaporator, the refrigeration compartment evaporator, and the variable-temperature compartment evaporator are connected in parallel and then connected in series with the freezing compartment evaporator.

[0090] The ice-making system of the above embodiments of this disclosure has the highest and inalienable control priority in the parallel operation of four systems. Other systems are not allowed to actively interrupt or reduce the load on the ice-making system, thereby significantly reducing the ice-making interruption rate and improving ice-making efficiency.

[0091] Figure 3 This is a schematic diagram of some other embodiments of the refrigerator disclosed herein. For example... Figure 3 As shown, the refrigerator disclosed herein may include a compressor A, a condenser B, a first electronic expansion valve C, a refrigerator compartment evaporator D1, a variable temperature compartment evaporator D2, an ice-making compartment evaporator D3, a freezer compartment evaporator D0, and a dynamic compensation port E.

[0092] Figure 3 This is a schematic diagram of the four-system refrigerator of this disclosure. Figure 3 As shown, the refrigerant output from compressor A enters the first electronic expansion valve C after passing through condenser B. The first electronic expansion valve C distributes the refrigerant in parallel to the evaporators D1 (refrigeration compartment), D2 (variable temperature compartment), and D3 (ice-making compartment). These three are connected in parallel, as indicated by the dashed box. After absorbing heat, the refrigerant flows to the evaporator D0 (freezer compartment) and finally returns to the compressor, forming a closed loop. The ice-making compartment evaporator D3 is a priority locking interface, connected to the dynamic compensation port E via a bidirectional arrow, demonstrating the compensation logic of the dynamic compensation port E for cooling capacity when ice making is prioritized.

[0093] The above embodiments of this disclosure provide a four-system coordinated cooling method for a multi-temperature zone refrigerator based on priority control of the ice-making system. The system consists of a refrigerator evaporator system, a variable-temperature evaporator system, and an ice-making evaporator system connected in parallel, which are then connected in series with the freezer compartment evaporator system. All four systems share a single variable-frequency compressor, and precise control is achieved through a first electronic expansion valve, a fan, and an MCU controller.

[0094] In some embodiments of this disclosure, the step of prioritizing the delivery of cold energy to the ice-making system may include: during ice making, cold energy is preferentially supplied to the evaporator of the ice-making chamber. This can be achieved by dynamically adjusting the opening of the electronic expansion valve. For example, when ice making is started, the system can adjust the distribution ratio of C, D1:D2:D3=3:3:4, to D1:D2:D3=1:1:8, so that more refrigerant flows to D3 (the evaporator of the ice-making chamber), while reducing the cold energy supply to D1 and D2.

[0095] In some embodiments of this disclosure, the step of preferentially delivering cold energy to the ice-making system may include at least one of steps 210 to 250.

[0096] In step 220, during the current ice-making cycle, the compressor inverter module is controlled to output stable power.

[0097] In step 220, the evaporator in the ice-making compartment and the evaporator in the freezing compartment are controlled to operate at full capacity. The full capacity operation means that the electronic expansion valves of the evaporators in the ice-making compartment and the freezing compartment are opened to the maximum degree (e.g., 90%), and the fan speed is at full speed.

[0098] In step 230, the variable temperature compartment evaporator and the refrigeration compartment evaporator are controlled to operate at reduced derating. The reduced derating operation means that the opening degree of the electronic expansion valve of the ice-making compartment evaporator and the freezing compartment evaporator is a predetermined opening degree (50% to 30%), and the fan speed is the speed corresponding to the predetermined opening degree, wherein the predetermined opening degree is less than the maximum opening degree.

[0099] The embodiments of this disclosure, for a four-system variable refrigerator where D1, D2, and D3 are connected in parallel and then in series with D0, can prioritize ensuring that the ice-making system completes the current ice-making cycle by controlling D1 / D2 to operate at reduced capacity and D3 / D0 to operate at full capacity. This can significantly reduce the ice-making interruption rate and improve ice-making efficiency.

[0100] In step 240, the opening degree of the electronic expansion valve and the fan speed of the evaporator in the cold compartment are increased, a stable compressor frequency is set, and the cooling capacity is compensated to the evaporator in the cold compartment through the dynamic compensation port E.

[0101] In some embodiments of this disclosure, the step of compensating the cold energy to the evaporator of the cold compartment through the dynamic compensation port E may include: compensating the cold energy of an external cold source to the evaporator of the cold compartment through the dynamic compensation port E.

[0102] In step 250, the opening degree of the electronic expansion valve and the fan speed of the variable temperature compartment evaporator are increased, a stable compressor frequency is set, and the cooling capacity is compensated to the variable temperature compartment evaporator through the dynamic compensation port E.

[0103] In some embodiments of this disclosure, the step of compensating the cooling capacity to the variable temperature compartment evaporator through the dynamic compensation port E may include: compensating the cooling capacity of an external cold source to the variable temperature compartment evaporator through the dynamic compensation port E.

[0104] In some embodiments of this disclosure, the compensation mechanism of the dynamic compensation port E mainly compensates for the lack of cooling capacity in other compartment evaporators (e.g., D1, D2, or D0) during ice-making state by increasing the opening of the electronic expansion valve, the fan speed (1500 RPM), and stabilizing the compressor frequency (45-50 Hz) of other compartment evaporators (e.g., D1, D2, or D0). For example, if a lack of cooling capacity is detected in any branch, the fan speed will be increased.

[0105] The above embodiments of this disclosure, through a dynamic compensation port, can realize dynamic compensation of the cooling capacity of the refrigeration and variable temperature systems, avoiding conflicts with the ice-making system, thereby improving the temperature control accuracy of multiple temperature zones.

[0106] The embodiments disclosed above use a dynamic compensation port as the core cooling capacity adjustment component. By monitoring the changes in cooling capacity demand of the refrigeration and variable temperature systems in real time, the opening degree of the evaporator in the refrigeration compartment or the evaporator in the variable temperature compartment (specifically, the opening degree of the electronic expansion valve next to the evaporator in the refrigeration compartment or the evaporator in the variable temperature compartment (70%-90%)), the fan speed and the compressor frequency are dynamically adjusted to achieve precise cooling capacity compensation, thereby avoiding ice-making interruption due to cooling capacity scheduling conflicts.

[0107] The embodiments disclosed above can dynamically compensate for the cooling demand of the refrigeration and variable temperature systems by adjusting the opening degree of the electronic expansion valve, the fan speed and the compressor frequency of the evaporator in the refrigeration compartment and the evaporator in the variable temperature compartment, thus avoiding conflicts with the ice-making system.

[0108] Figure 4 This is a schematic diagram of some other embodiments of the refrigerator ice-making control method disclosed herein. Figure 4 The embodiments can be executed by the refrigerator or controller of this disclosure. For example... Figure 4 As shown, Figure 4 The method of the embodiment may include at least one of steps 41 to 47.

[0109] In step 41, refrigerator data is acquired, wherein the refrigerator data includes at least one of temperature data, evaporator operating status data, and ice-making request data.

[0110] The embodiments disclosed above can accurately determine whether the ice-making system and the temperature zone control system simultaneously request cold output based on refrigerator data, thereby prioritizing the completion of the current ice-making cycle by the ice-making system, significantly reducing the ice-making interruption rate and improving ice-making efficiency.

[0111] In some embodiments of this disclosure, the temperature data may include temperature data of at least one of nine temperature zones, such as the refrigerator compartment, the refrigerator compartment evaporator, the ice-making compartment, the ice-making compartment evaporator, the freezer compartment, the freezer compartment evaporator, the variable temperature compartment, the variable temperature compartment evaporator, and the compressor exhaust pipe.

[0112] In some embodiments of this disclosure, the evaporator operating status data may include operating status data of at least one of a refrigeration compartment evaporator, an ice-making compartment evaporator, a freezer compartment evaporator, and a variable temperature compartment evaporator.

[0113] The embodiments disclosed above can more accurately determine whether the ice-making system and the temperature zone control system are simultaneously requesting cold output based on data from 9 temperature zones, operating status data of D0-D3, and ice-making request data. This can prioritize ensuring that the ice-making system completes the current ice-making cycle, significantly reduce the ice-making interruption rate, and improve ice-making efficiency.

[0114] In step 42, it is determined whether the ice-making system and the temperature zone control system simultaneously request cooling output based on the refrigerator data.

[0115] In step 43, when both the ice-making system and the temperature zone control system request cooling output simultaneously, it is determined whether the operating status of the evaporator in the freezer compartment meets the cooling requirements of the freezer compartment.

[0116] In step 44, if the operating status of the evaporator in the freezer compartment meets the cooling requirements of the freezer compartment, the cold energy is preferentially delivered to the ice-making system to ensure that the ice-making system completes the current ice-making cycle.

[0117] In some embodiments of this disclosure, the refrigerator ice-making control method may include: when the user starts the ice-making function or the system detects that ice needs to be made, if the ice full detection is not triggered and the water level is normal, the MCU immediately activates the highest priority mechanism of the ice-making system, that is, immediately executes the step of prioritizing the delivery of cold energy to the ice-making system.

[0118] In some embodiments of this disclosure, step 44, the step of preferentially delivering cold energy to the ice-making system, may include at least one of steps 210 to 250.

[0119] In step 45, after the ice-making system starts making ice, the refrigerator enters the ice-making cycle.

[0120] In step 46, during the ice-making cycle, the ice-making lock state is maintained, and temperature fluctuations in the temperature zone control system will not trigger changes in the cooling capacity scheduling priority.

[0121] In the embodiments described above, when the ice-making process is started, the system enters a "locked state". During this period, temperature fluctuations in other temperature zones will not trigger changes in the priority of cooling capacity scheduling, ensuring that the ice-making process is not disturbed.

[0122] The above embodiments of this disclosure employ an ice-making operation state locking mechanism. After ice making is started, the system enters a locking period and remains unaffected by changes in other temperature zones within a set period, thereby further ensuring that the ice-making process is not disturbed.

[0123] In some embodiments of this disclosure, the ice-making cycle (lock-in cycle) can be set according to the actual ice-making time requirements.

[0124] In some embodiments of this disclosure, the ice-making cycle can be set to 30 minutes.

[0125] In some embodiments of this disclosure, the ice-making cycle can be set to 40 minutes.

[0126] Figure 5 This is a schematic diagram of the operation lock-in curve of the ice-making process in some embodiments of this disclosure. Figure 5 This is a schematic diagram of the ice-making and locking operation curves when the four systems of this disclosure are working simultaneously. Figure 5 As shown, the second curve from the bottom represents the temperature of the ice-making evaporator, which is locked at -18℃±0.5℃ for 0-40 minutes, and then rises to -10℃ after 40 minutes, indicating that ice making is complete. The second curve from the top on the left represents the temperature of the refrigeration evaporator, which allows for a wider fluctuation range of 2℃~8℃ during the locked period (normally 3℃±1℃), reflecting derating operation. The third curve from the top on the left represents the temperature of the variable temperature evaporator, which is maintained at -5℃~5℃ during the locked period, retaining basic functions. The first curve from the bottom is the temperature of the freezing evaporator, which is stable at -22℃ during the locked period (normally -18℃), using ultra-low temperature enhancement to compensate for cooling capacity. The first curve from the top on the left represents the total system power, which is stable at 240W during the locked period, with a normal fluctuation of 180~280W, demonstrating the energy consumption stability under priority control.

[0127] In some embodiments of this disclosure, during an ice-making cycle (e.g., 40 minutes), the system enters an "operational lockout state," preventing ice-making load reduction or shutdown even if other temperature zones experience an emergency temperature rise. After the ice-making task is completed, the system automatically releases its priority, resumes multi-system collaborative control, and records the operation data.

[0128] The system described in the above embodiments of this disclosure can achieve independent temperature control in multiple temperature zones, and when the four systems are working simultaneously, the ice-making process is continuous and stable with no risk of interruption.

[0129] The embodiments disclosed herein aim to solve the technical problem that the ice-making function is easily interrupted when multiple systems are running in parallel. The embodiments of this disclosure establish a "highest priority ice-making system" control mechanism, combined with a dynamic compensation port as the cooling capacity adjustment center, to achieve efficient and independent control of nine temperature zones while ensuring that the ice-making process is not interrupted when four systems are operating simultaneously.

[0130] In step 47, if the operating status of the freezer evaporator does not meet the cooling demand of the freezer compartment, the opening of the electronic expansion valve and the fan speed of the freezer evaporator are increased, a stable compressor frequency is set, and the cooling capacity is compensated to the freezer evaporator through the dynamic compensation port E.

[0131] In some embodiments of this disclosure, step 47 may include: compensating the cooling capacity of the external cold source to the evaporator of the freezer compartment via the dynamic compensation port E.

[0132] In some embodiments of this disclosure, step 47 may include: the evaporator (D0) of the freezer compartment can actively improve its own cooling capacity output through a triple self-enhancement mechanism (dynamically increasing the opening of the electronic expansion valve to 70%-90%, synchronously increasing the fan speed to 1500RPM, and stabilizing the compressor frequency at 45-50Hz).

[0133] The embodiments disclosed above meet the refrigeration requirements of the freezer compartment by adjusting the opening of the electronic expansion valve of the freezer compartment evaporator, the fan speed, and the compressor frequency.

[0134] Figure 6 This is a schematic diagram of some embodiments of the refrigerator ice-making control method disclosed herein. Figure 6 The embodiments can be executed by the refrigerator or controller of this disclosure. The ice-making control method of the refrigerator of this disclosure may include, in addition to... Figure 1 , Figure 2 or Figure 4 In addition to the method in the embodiments, it may also include, for example, Figure 6 The embodiment includes at least one of steps 61 to 63.

[0135] In step 61, the user's historical usage behavior and environmental parameters are obtained.

[0136] In step 62, based on the user's historical usage behavior and the environmental parameters, a low-load period is predicted, wherein the low-load period is a period in which the load rate is less than a first threshold.

[0137] In some embodiments of this disclosure, the low-load period may be a nighttime low-load period.

[0138] In some embodiments of this disclosure, the low-load period may be 2:00-4:00.

[0139] In some embodiments of this disclosure, low load (load rate ≤ 50%, cooling capacity ≤ 80W) does not mean low power, but rather refers to low cooling demand, which can also be understood as the electronic expansion valve allocating less cooling capacity to each compartment evaporator. For example: 1. Due to different demands, the load rate may increase from 46.8% (low load) to 81.2% (high load), but the compressor power remains 235W (high power); 2. The load rate can also be understood as the amount of ice in the ice maker; a low load rate means less ice, thus initiating the ice-making mode.

[0140] In step 63, the ice-making task is automatically started during the low-load period.

[0141] The above-described embodiments of this disclosure employ an intelligent scheduling algorithm for ice-making tasks based on user behavior and environmental parameters. This algorithm enables ice-making tasks to start automatically during low-load periods, thereby further reducing the overall system interference risk.

[0142] The embodiments disclosed above predict low-load periods based on users' historical usage behavior (such as door opening frequency and ice-making time) and environmental parameters (such as ambient temperature and humidity), and automatically start the ice-making task during the period to reduce the impact on the control of other temperature zones and improve the overall energy efficiency ratio.

[0143] The embodiments disclosed above utilize an intelligent scheduling algorithm based on user behavior and environmental parameters to automatically start the ice-making task during low-load periods, thereby reducing the overall system interference risk.

[0144] Figure 7 This is a schematic diagram of some embodiments of the refrigerator ice-making control method disclosed herein. Figure 7 The embodiments can be executed by the refrigerator or controller of this disclosure. The ice-making control method of the refrigerator disclosed herein (e.g.) Figure 2 Example Step 200 or Figure 4 The step of prioritizing the delivery of cold energy to the ice-making system in step 44 of the embodiment may include, for example: Figure 7 The embodiment includes at least one of steps 71 to 76.

[0145] In step 71, the current load rate of the refrigerator is obtained.

[0146] In step 72, it is determined whether the current load rate is less than the first threshold.

[0147] In step 73, if the current load rate is less than the first threshold, the step of prioritizing the delivery of cold energy to the ice-making system is performed.

[0148] In some embodiments of this disclosure, the first threshold may be 50%.

[0149] The embodiments disclosed above can maintain ice-making priority scheduling when the load is below a threshold (load rate <50%), thereby ensuring that the ice-making system completes the current ice-making cycle under low load conditions, which can significantly reduce the ice-making interruption rate and improve ice-making efficiency.

[0150] In step 74, it is determined whether the current load rate is greater than a second threshold, wherein the second threshold is greater than the first threshold.

[0151] In some embodiments of this disclosure, the second threshold may be 70%.

[0152] In step 75, if the current load rate is greater than the second threshold, the ice-making task is postponed to a low-load period, wherein the low-load period is the period when the load rate is less than the first threshold.

[0153] In some embodiments of this disclosure, step 75 may include: if the system detects that the current load is higher than a threshold (load rate > 70%), then automatically postpone the ice-making task to a low-load period (e.g., 2:00-4:00).

[0154] The embodiments disclosed above can avoid temperature control fluctuations caused by heat dissipation under high load.

[0155] In step 76, if the current load rate is greater than or equal to the first threshold and less than or equal to the second threshold, the process is buffered for a first predetermined time, and after the load stabilizes, the steps of obtaining the current load rate of the refrigerator and determining whether the current load rate is less than the first threshold are executed again. The ice-making operation is not started and the ice-making priority is not changed.

[0156] In some embodiments of this disclosure, the first predetermined time may be 10 minutes.

[0157] In the embodiments described above, if the current load rate is detected to be between 50% and 70%, a buffering mechanism is activated to buffer for 10 minutes to wait for the load to stabilize and to monitor the load status at all times. Ice making is not started, but the ice making priority is not changed.

[0158] The embodiments disclosed above improve the overall energy efficiency of the system by optimizing the task scheduling window while ensuring the continuity of the ice-making process, and at the same time reduce the temperature fluctuation range of multiple temperature zones.

[0159] The embodiments disclosed above further improve system energy efficiency and temperature control stability while ensuring the continuity of ice-making function.

[0160] The embodiments disclosed herein achieve a comprehensive technical effect of improving system energy efficiency ratio (COP) and user experience through the combined effect of the above-mentioned technical features.

[0161] The embodiments disclosed above achieve efficient coordination between independent control of multiple temperature zones and ice-making function through the above control mechanism, thereby improving user satisfaction and being particularly suitable for high-end smart refrigerator application scenarios.

[0183] Figure 2 This is a schematic diagram of the structure of some embodiments of the refrigerator disclosed herein. For example... Figure 2 As shown, the refrigerator disclosed herein may include a temperature zone control system 11, an ice-making system 12, and a controller 13.

[0184] Temperature zone control system 11, wherein the temperature zone control system 11 may include at least one of a refrigeration system, a cold storage system, and a variable temperature system, wherein the refrigeration system includes, for example, a refrigeration system, a variable temperature system, and a variable temperature system. Figure 3 The evaporator D0 of the freezer compartment shown is included in the refrigeration system. Figure 3 The evaporator D1 in the refrigeration compartment shown, the variable temperature system includes, as follows: Figure 3 The variable temperature chamber evaporator D2 is shown.

[0185] Ice-making system 12, wherein ice-making system 12 may include, for example Figure 3 The evaporator D3 in the ice-making chamber is shown.

[0186] Controller 13 may be a controller as described in any of the above embodiments.

[0187] In some embodiments of this disclosure, when a user starts the ice-making function or the system detects that ice needs to be made, if the ice full detection is not triggered and the water level is normal, the controller 13 immediately activates the highest priority mechanism of the ice-making system.

[0188] In some embodiments of this disclosure, the refrigerator may include a refrigerator ice-making control system.

[0189] In some embodiments of this disclosure, the refrigerator ice-making control system may include a signal acquisition layer, a decision layer, an execution layer, and a feedback layer, wherein the decision layer may be implemented by the controller 13.

[0190] In some embodiments of this disclosure, the signal acquisition layer includes nine temperature sensors, four operating status monitors, and one ice-making request trigger.

[0191] In some embodiments of this disclosure, the 9-channel temperature sensor includes a dedicated sensor for the ice-making module.

[0192] In some embodiments of this disclosure, the nine-channel temperature sensor includes temperature sensors respectively installed in nine temperature zones, such as the refrigerator compartment, the refrigerator compartment evaporator, the ice-making compartment, the ice-making compartment evaporator, the freezer compartment, the freezer compartment evaporator, the variable temperature compartment, the variable temperature compartment evaporator, and the compressor exhaust pipe.

[0193] In some embodiments of this disclosure, a four-channel operating status monitor is used to monitor and detect the operating status of each evaporator, including the evaporator D1 in the refrigeration compartment, the evaporator D2 in the variable temperature compartment, the evaporator D3 in the ice-making compartment, and the evaporator D0 in the freezer compartment. The operating status includes data such as current, voltage, and refrigerant flow rate.

[0194] In some embodiments of this disclosure, a 1-channel ice-making request trigger is used to output a multi-system coordination signal, namely, a coordination signal for the four systems consisting of four evaporators: refrigeration, variable temperature, freezing, and ice making.

[0195] In some embodiments of this disclosure, the core of the decision layer is a priority arbitration module with a built-in ice-making locking algorithm. After receiving a signal, it performs two-step judgment: 1. Whether there is an ice-making request, 2. Whether the freezing compensation capability meets the standard. If there is an ice-making request and the freezing compensation capability meets the standard, it outputs a priority instruction, i.e., D3 > D0 > D1 / D2.

[0196] In some embodiments of this disclosure, the decision layer can be configured to, when there is an ice-making request, only execute ice-making priority control if the operating state of the evaporator in the freezer compartment can stably meet the cooling demand; if the freezing compensation capability is not up to standard, dynamic compensation control in segment E needs to be executed, and then the data from each sensor will be collected again and the instructions will be judged cyclically.

[0197] In some embodiments of this disclosure, the execution layer can be configured to first use an electronic expansion valve controller to regulate the refrigerant distribution, forcing the parallel section of cooling capacity to be preferentially delivered to the ice-making evaporator, preventing other systems from occupying the cooling capacity channel, and controlling the compressor inverter module to output stable power. Then, it controls the evaporator start / stop relay to execute "lock / derating / compensation" commands, such as making D1 / D2 operate at derating and D3 / D0 operate at full power. Afterward, dynamic compensation of cooling capacity can be achieved by adjusting the opening of the electronic expansion valve, fan speed, and compressor frequency of the refrigeration and variable temperature compartment evaporators.

[0198] In some embodiments of this disclosure, derating operation refers to the continuous adjustment of the opening of the electronic expansion valve (e.g., D1 opening from 50% to 30%) and the synchronous adjustment of the fan speed.

[0199] In some embodiments of this disclosure, full-power operation of D3 / D0 refers to the state where the electronic expansion valve of D3 / D0 is at its maximum opening (90%) and the fan is running at full speed.

[0200] In some embodiments of this disclosure, the feedback of all executed commands is collected in real time by the status monitoring module, which collects the temperature and power data of each evaporator and feeds them back to the decision-making layer in a closed loop to ensure a control accuracy of ±0.5℃.
