Description

Technical Field

[0001] This application relates to the field of electrical technology, specifically to a refrigeration equipment control method, device, refrigerator, and computer-readable storage medium. Background Technology

[0002] In existing technologies, refrigerator noise reduction strategies or solutions typically employ a preset "quiet mode," which simply limits the compressor and fan to a fixed low speed. This mode sacrifices cooling efficiency and cannot meet noise reduction requirements under high load conditions. Alternatively, existing technologies for addressing refrigerator noise reduction typically only control the noise level based on the decibel level produced by the refrigerator. This lacks a comprehensive assessment of the overall system load and cannot guarantee a certain level of cooling performance while meeting noise reduction requirements. Summary of the Invention

[0021] This application provides a refrigeration equipment control method, apparatus, device, and storage medium, which are described in detail below.

[0024] It should be noted that, Figure 1 The schematic diagram of the refrigeration equipment control system shown is merely an example.

As those skilled in the art will know, with the evolution of refrigeration equipment control systems and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0025] like Figure 2 As shown, Figure 2 This is a schematic flowchart of an embodiment of the refrigeration equipment control method in this application. The method specifically includes the following steps 201 to 204: 201. Obtain the current sound information generated by the target refrigeration equipment.

[0026] In this embodiment, the target refrigeration equipment generates noise during operation due to the operation of components such as the compressor and fan. Therefore, the target refrigeration equipment produces sound information during operation. Based on this, in this embodiment, a sound sensor can be installed at any suitable location on the target refrigeration equipment to acquire the current sound information generated by the target refrigeration equipment itself.

[0027] 202. Determine the current target load type of the target refrigeration equipment.

[0028] In the workflow of a target refrigeration device, it typically includes at least several stages. For example, the target refrigeration device may be in the refrigeration process stage; or, after completing the refrigeration process, it may be in a stage of maintaining the refrigeration temperature; or, after refrigeration, the achieved temperature is much lower than the set temperature, the refrigeration device may be in a shutdown or standby stage. Therefore, the target refrigeration device in different stages has different load types, i.e., different load levels, such as high load, medium load, low load, or no load. Thus, the current target load type can be considered as high load, medium load, low load, or no load.

[0029] In this embodiment, to determine the current target load type, it can be determined based on the current mode of the target refrigeration equipment. For example, when the target refrigeration equipment is in refrigeration mode, it can be a high load type or a medium load type. At this time, it can be further determined as a high load or a medium load based on the temperature difference between the current temperature and the set temperature. When the target refrigeration equipment is in noise reduction mode, it is a low load type. When the target refrigeration equipment is in shutdown or standby mode, it is a no load type. Of course, this embodiment can also determine the load type based on the specific power value of the compressor. For example, the higher the power, the higher the load type, and the lower the power, the lower the load type. Specifically, this embodiment does not limit it.

[0030] 203. Determine whether the current audio information needs to be adjusted based on the current target load type.

[0031] In existing technologies, noise control of refrigeration equipment can be achieved by reducing noise at the current decibel level or by limiting the compressor power. However, existing technologies do not consider normal cooling needs in terms of noise reduction. Therefore, in this embodiment, after determining the current target load type of the target refrigeration equipment, it can be determined whether the current target load type is a high load type. If it is a high load type, it can be determined that the target refrigeration equipment is in a stage requiring cooling. In this case, noise reduction would limit the noise reduction effect of the target refrigeration equipment. Therefore, to avoid a decrease in the cooling effect of the target refrigeration equipment, it is determined that the current sound information does not need to be adjusted during a high load type. Conversely, if the current target load type is not a high load type, it can be determined that the compressor of the target refrigeration equipment does not need to operate at high power. In this case, noise reduction will not affect its cooling effect. In other words, when in a non-high load type, it can be determined that the current sound information needs to be adjusted. At this time, adjustment can be made according to the specific decibel level of the current sound information, such as reducing a specific decibel percentage or reducing it below a certain decibel level. This embodiment does not limit this adjustment.

[0032] 204. If it is determined that the current sound information needs to be adjusted, adjust the compressor speed and / or fan speed of the target refrigeration equipment to reduce the volume corresponding to the current sound information.

[0033] In this embodiment, if it is determined that the current sound information needs adjustment according to the above steps, it means that the noise generated by the target cooling device needs to be reduced. Since the current sound information is generated by the operation of the target cooling device, and the sources of sound generated when the target cooling device is working include the compressor and the fan, the compressor speed and / or fan speed can be reduced. For example, if it is determined that the current sound information needs adjustment, the compressor speed can be appropriately reduced, such as reducing the compressor speed by one unit step or reducing the compressor speed level; or, the fan speed can be appropriately reduced, such as reducing the fan speed by one level; or the compressor speed and fan speed can be reduced by one level at the same time. The specific speed reduction scheme can be set according to the actual situation. For example, if the cooling temperature is closer to the user-set target temperature, the fan speed and compressor speed can be reduced at the same time; if the cooling temperature is higher than the fan speed, only the compressor speed or fan speed can be reduced to maintain a certain cooling capacity.

[0034] Therefore, the refrigeration equipment control method provided in this application can first acquire the current sound information generated by the target refrigeration equipment during operation and determine the current target load type of the target refrigeration equipment. Then, based on the specific target load type, it can be determined whether the volume of the current sound information needs to be adjusted. For example, when the load type is large, the volume of the current sound information can be dynamically limited, thereby ensuring both cooling and noise reduction. This solves the problem in existing technologies where noise reduction cannot guarantee the cooling effect.

[0035] To better implement the embodiments of this application, in one embodiment of this application, determining the current target load type of the target refrigeration device includes: Obtain the current operating parameters of the compressor in the target refrigeration equipment and the current temperature of the refrigeration chamber in the target refrigeration equipment; determine the current target load type of the target refrigeration equipment based on the current operating parameters and the current temperature.

[0036] The above embodiments provide a scheme for determining the current target load type of the target refrigeration equipment based on its current mode. Furthermore, this application also provides an implementation method. Specifically, in this application embodiment, during the operation of the target refrigeration equipment, the processor of the target refrigeration equipment can obtain the current operating parameter information of the compressor, such as the current power and current speed. Simultaneously, it can also obtain the current temperature information from temperature sensors in the refrigeration compartments of the target refrigeration equipment, such as the current temperature information of the refrigerator compartment and the freezer compartment. At this time, the compressor load can be determined first based on the compressor's current power and current speed. For example, if the compressor power is greater than a certain power threshold and the compressor speed is also greater than a certain speed threshold, the compressor can be determined to be under high load; or, if the compressor power is less than the power threshold and the compressor speed is less than the speed threshold, the compressor can be determined to be under low load; or, if either the compressor power or the compressor speed is greater than the corresponding threshold, the compressor can be determined to be under medium load. Next, based on the current temperature information of the cooling room, the temperature difference between it and the ambient temperature is determined. This determines whether further cooling is needed or not. If cooling is needed and the compressor load is high or medium, the compressor needs to increase its power or speed, and the target cooling equipment's load type can be high. If cooling is needed and the compressor load is low, the target cooling equipment's load type can be medium. If the compressor load is medium or low and further cooling is not needed, the target cooling equipment's load type can be low. By first determining the compressor load and then using the cooling room temperature information to determine the target cooling equipment's load type, the compressor load can be predicted using the cooling room temperature information, thus enabling pre-judgment of the target cooling equipment's load type and facilitating subsequent noise reduction control.

[0037] To better implement the embodiments of this application, in one embodiment, the current operating parameter information includes compressor power change information and compressor speed change information; based on the current operating parameter information and the current temperature information, the current target load type of the target refrigeration equipment is determined, including: Based on the power change information and speed change information, determine the current energy efficiency information; obtain the current set temperature information of the target refrigeration equipment; determine the target temperature difference information between the current temperature information and the current set temperature information; and determine the current target load type based on the current energy efficiency information and the target temperature difference information.

[0038] The above embodiments provide a scheme for determining the target load type of a target refrigeration device by using the operating parameters of the compressor and the current temperature of the refrigeration chamber. In addition, this application also provides an implementation method.

[0039] Specifically, in this embodiment, the compressor power change information is the change in compressor power per unit time, and the compressor speed change information is the change in compressor speed per unit time. This unit time can be any unit time, and this embodiment does not limit it. Furthermore, in this embodiment, the current energy efficiency information can be determined based on the power change information and the speed change information according to formula (1), as shown below: K=ΔP / ΔV……(1) In formula (1), K represents the current energy efficiency information, ΔP represents the power change information, and ΔV represents the speed change information.

[0040] It should also be noted that in this embodiment, the currently set temperature information is the target cooling temperature set by the user, such as 8 degrees Celsius, 5 degrees Celsius, etc. In this case, the target temperature difference information is obtained by subtracting the current temperature information from the currently set temperature information. In this embodiment, after obtaining the current energy efficiency information and the target temperature difference information, if either the current energy efficiency information or the target temperature difference information is less than the corresponding numerical threshold, the current target load type of the target cooling device can be determined to be low load; or, if either the current energy efficiency information or the target temperature difference information is greater than the corresponding numerical threshold, the current target load type of the target cooling device can be determined to be high load; if either the current energy efficiency information or the target temperature difference information is greater than the corresponding numerical threshold, and the other is less than the corresponding numerical threshold, the current target load type of the target cooling device can be determined to be medium load. This method allows for real-time determination of the load type of the target cooling device, ensuring timely data confirmation.

[0041] To better implement the embodiments of this application, in one embodiment, the current target load type includes a first load type and a second load type; determining the current target load type based on current energy efficiency information and target temperature difference information includes: If the current energy efficiency information value is less than the first target threshold and the target temperature difference information value is less than the second target threshold, the first load type is determined; if the current energy efficiency information value is greater than or equal to the first target threshold or the target temperature difference information value is greater than or equal to the second target threshold, the second load type is determined.

[0042] The above embodiments provide a scheme for determining the current target load type based on current energy efficiency information and target temperature difference information. In practical application scenarios, determining whether the target cooling equipment needs noise reduction is usually based on a certain threshold. For example, if it is a high load, noise reduction is not required temporarily; if it is a low or medium load, noise reduction can be performed. Therefore, in this embodiment, the current target load type is divided into a first load type and a second load type. The first load type can correspond to load types that require noise reduction, such as low load type and medium load type, while the second load type can correspond to load types that do not require noise reduction, such as high load type.

[0043] Based on this, in this embodiment, if the current energy efficiency information value is less than a first target threshold and the target temperature difference information value is less than a second target threshold, then a first load type requiring noise reduction is determined; if the current energy efficiency information value is greater than or equal to the first target threshold or the target temperature difference information value is greater than or equal to the second target threshold, then a second load type not requiring noise reduction is determined. After determining the corresponding load type, subsequent noise reduction control can be performed according to any of the above embodiments.

[0044] To better implement the embodiments of this application, in one embodiment, determining whether the current audio information needs adjustment based on the current target load type includes: Based on the current target load type, determine the corresponding target volume threshold; if the volume of the current sound information is less than the target volume threshold, determine that the current sound information does not need to be adjusted; if the volume of the current sound information is greater than or equal to the target volume threshold, determine that the current sound information needs to be adjusted.

[0045] The above embodiments provide an implementation method for determining whether noise reduction is needed based on the current target load type. However, in practice, if the current target load type is a high load type, not performing noise reduction at all will affect the user experience. Therefore, determining whether noise reduction is needed solely based on the load type also has certain problems. Therefore, this application embodiment also provides an implementation method in which different noise thresholds can be preset for different load types. In this case, if the current target load type is determined, the corresponding noise threshold can be determined. For example, if the current target load type is a high load type, it can correspond to a noise threshold A; if the current target load type is a medium load type, it can correspond to a noise threshold B; if the current target load type is a low load type, it can correspond to a noise threshold C, etc., where noise threshold A is greater than noise threshold B, and noise threshold B is greater than noise threshold C. Based on this, different load types correspond to different noise thresholds, and the higher the load type, the larger the corresponding noise threshold value. The advantage of this is that a higher load type indicates a greater need for cooling, resulting in louder noise from the cooling equipment. A higher noise threshold can be considered a more lenient noise judgment condition, making it less likely to trigger noise reduction. Conversely, a lower load type indicates that the cooling equipment does not need cooling, resulting in quieter noise from the equipment. A lower noise threshold can be considered a more restrictive noise judgment condition, making it easier to trigger noise reduction. This allows for dynamic noise reduction, ensuring that under high loads, light noise reduction is implemented to maintain cooling, while under low loads, noise reduction is prioritized, and cooling may be appropriately sacrificed. Then, based on the determined dynamic noise threshold, the current sound information is used to determine whether noise reduction is necessary.

[0046] To better implement the embodiments of this application, in one embodiment, if it is determined that the current sound information needs to be adjusted, the compressor speed and / or fan speed of the target refrigeration equipment are adjusted, including: If the current target load type is the first load type, determine the target heat dissipation temperature of the heat dissipation object corresponding to the fan in the target refrigeration equipment and determine the target fan speed corresponding to the target heat dissipation temperature; reduce the current compressor speed of the compressor and the current fan speed of the fan to the target fan speed; if the current target load type is the second load type, maintain or reduce the current compressor speed of the compressor, wherein the reduction in the current compressor speed is less than the reduction in the current compressor speed when the current target load type is the first load type; determine the user's hearing-sensitive frequency band; adjust the current fan speed so that the audio frequency band generated by the adjusted fan speed does not belong to the user's hearing-sensitive frequency band.

[0047] In the above embodiments, the first load type can be a load type that requires noise reduction, and the second load type can be a type that does not require noise reduction. Since this application also provides an implementation method for determining whether to perform noise reduction based on the noise threshold corresponding to the load type, in this embodiment, the first load type can also be a light load type, in which case a more aggressive noise reduction strategy can be implemented; while the second load type can be a heavy load type, in which case a more conservative noise reduction strategy can be implemented.

[0048] Based on this, in this embodiment, if the current target load type is the first load type, the target heat dissipation temperature of the heat dissipation object corresponding to the fan in the target refrigeration equipment, i.e., the heat dissipation temperature of the condenser, can be determined first. Simultaneously, based on the heat dissipation strategy, the heat dissipation temperature of the condenser is usually also limited by the program, i.e., the required fan speed for different condenser temperatures, which can be obtained from the program. At this time, the current temperature of the condenser can be monitored through the condenser's temperature sensor. If the fan speed is gradually reduced to the target fan speed, and the condenser temperature can be maintained at the design temperature for normal operation, then the speed reduction can be determined to be complete. Furthermore, the logic for reducing the compressor speed can include reducing the speed by one compressor speed setting or reducing the compressor speed by one step; specific implementations in this embodiment do not limit this.

[0049] Furthermore, if the current target load type is the second load type, a restrictive noise reduction strategy can be implemented. This allows the compressor's current speed to be maintained or reduced, with the reduction being less than the reduction when the target load type is the first load type. Additionally, in this embodiment, the user's hearing-sensitive frequency band can be a preset, harsh frequency band, which can be user-defined. After obtaining the user's hearing-sensitive frequency band, the current fan speed is adjusted to a non-user hearing-sensitive frequency band. Because the fan speed deviates from the user's hearing-sensitive frequency band, the impact of the refrigeration equipment noise on the user is reduced, thus achieving a noise reduction effect.

[0050] It should be noted that, under normal circumstances, the determination of whether to maintain or reduce the compressor speed in maintaining or reducing the current compressor speed can be based on whether the current sound information after the fan speed adjustment is less than the noise threshold corresponding to the second load type. If it is less, the compressor speed is maintained; if it is not less, the compressor speed is reduced.

[0051] To better implement the embodiments of this application, in one embodiment, if it is determined that the current sound information needs to be adjusted, after adjusting the compressor speed and / or fan speed of the target refrigeration equipment, the method further includes: If the current cooling temperature is determined to be higher than the user-set target cooling temperature, the fan speed is increased within the target time period; the compressor speed is controlled to increase according to the preset compressor speed smoothing curve.

[0052] In any of the above embodiments, different noise reduction schemes are provided. However, in the prior art, if the refrigeration equipment resumes cooling, its control logic will cause the compressor or fan to suddenly increase its speed, resulting in a large change in the sound value produced by the refrigeration equipment. Such a large change in sound can severely disturb the user. For example, when a user suddenly moves from a quiet environment to a noisy one, the user's perception will be very noticeable. To avoid this situation, this application also provides an implementation method.

[0053] Specifically, if the current cooling temperature is determined to be higher than the user-set target cooling temperature, the refrigeration equipment needs to cool. At this time, the heat dissipation demand of the refrigeration equipment increases. Therefore, the fan speed can be increased within a short target time period to increase heat dissipation capacity. It should be noted that in refrigeration equipment, the compressor is the largest source of noise, while the fan generates relatively less noise. Therefore, the fan speed does not need to be increased gradually. It should also be noted that a smooth compressor speed increase curve ensures that the compressor speed increases smoothly, avoiding sudden increases in compressor speed and thus preventing users from suddenly perceiving a surge in noise. In summary, controlling the compressor speed to increase steadily in a smooth manner can prevent users from suddenly perceiving drastic changes in noise, while the increase in fan speed also ensures heat dissipation. The smooth compressor speed increase curve can be adaptively set according to the compressor model and specific rated power; this application embodiment does not limit it.

[0054] In summary, if the refrigeration equipment is operating at night, the load type is assessed as "light load," and the dynamic noise threshold for this type can be set to 35dB. If the current noise level of the refrigeration equipment exceeds 35dB, the compressor's current speed can be reduced, for example, to a low-frequency operation of 800rpm. Simultaneously, the control unit slightly reduces the condenser fan speed by 50rpm. If the noise level drops to 34.5dB after adjustment, the speed adjustment is complete. Because the load is light and the heat dissipation requirement is low, the cooling effect is not significantly affected by this solution. Alternatively, if the user places a large amount of room-temperature food inside, causing the room temperature to rise rapidly, the load type is reassessed as "heavy load," and the dynamic noise threshold is automatically widened to 45dB, corresponding to the heavy load type. The compressor speed increases to 1500rpm, reaching a noise level of 47dB. To accommodate the quick-freezing requirement, the control unit does not immediately reduce the compressor speed but instead increases the condenser fan speed by 10% to enhance heat dissipation and ensure continuous efficient compressor operation. Simultaneously, the evaporator fan is controlled to operate in a specific non-constant speed mode to break up airflow resonance. After 30 seconds, the internal heat load pressure decreased slightly, and the control unit then gradually reduced the compressor speed to 1450 rpm in a very smooth manner, decreasing by 20 rpm every 5 seconds, ultimately stabilizing the noise at 44 dB, maximizing the cooling speed within an acceptable noise range.

[0055] Furthermore, in this embodiment, after each adjustment of the compressor or fan speed by the refrigeration equipment, the adjustment range, the change in noise before and after the adjustment, and the change in refrigeration temperature before and after the adjustment can be recorded to form a historical dataset. Then, through machine learning algorithms (such as reinforcement learning), the specific decision-making logic is continuously optimized, enabling the system to adapt to individual differences (such as installation environment and refrigerant charge) and aging, achieving a noise reduction effect that becomes increasingly intelligent with use. For example, based on the historical dataset, it was found that at an ambient temperature of 30℃ and a "medium load" load type, the strategy of "compressor speed reduced by 50 rpm + condenser fan speed reduced by 30 rpm" resulted in 0.8 dB lower overall noise and 5% faster cooling speed compared to the strategy of "compressor speed reduced by 80 rpm only." The system updates this experience to the strategy library. When encountering similar operating conditions again, the learned optimal collaborative strategy is prioritized.

[0056] To better implement the refrigeration equipment control method in the embodiments of this application, a refrigeration equipment control device is also provided in the embodiments of this application, such as... Figure 3 As shown, the device 300 includes: The acquisition module 301 is used to acquire the current sound information generated by the target refrigeration device; Module 302 is used to determine the current target load type of the target refrigeration equipment; The determining module 302 is also used to determine whether the current sound information needs to be adjusted based on the current target load type; The control module 303 is used to adjust the compressor speed and / or fan speed of the target refrigeration equipment to reduce the volume corresponding to the current sound information if it is determined that the current sound information needs to be adjusted.

[0057] The refrigeration equipment control device provided in this application allows the acquisition module 301 to first acquire the current sound information generated by the target refrigeration equipment during operation and determine the current target load type of the target refrigeration equipment. Then, the determination module 302 can determine whether the volume of the current sound information needs to be adjusted based on the specific target load type.
