[0002] With the upgrading of domestic energy efficiency standards to Level 1 and the improvement of European energy-saving standards, the market has placed higher demands on refrigerator energy efficiency. Approximately 10% of a refrigerator system's energy consumption is used for defrosting, a significant proportion. Effectively optimizing the energy consumption of defrosting can improve the overall energy efficiency of the refrigerator.
[0003] Currently, refrigerators typically have two defrosting modes, high and low, which allow for simple adjustments to the defrosting power, resulting in poor energy efficiency. Summary of the Invention
[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a control method, apparatus, and refrigeration equipment for refrigeration equipment, which can reduce energy consumption and improve energy-saving performance.
[0005] In a first aspect, this application provides a control method for a refrigeration device, the method comprising:
[0006] In the acquisition step, when the duration of the defrosting action performed by the refrigeration equipment according to the first defrosting power reaches the first target duration, the first temperature data of the evaporator location of the refrigeration equipment at the first target time is acquired.
[0007] The adjustment steps involve determining whether the first temperature data is less than a temperature threshold. If the first temperature data is less than the temperature threshold, the second temperature data of the evaporator's location at the second target time is obtained. Based on the first temperature data and the second temperature data, the second defrosting power of the refrigeration equipment is determined, and the refrigeration equipment is controlled to perform the defrosting action at the second defrosting power.
[0008] Repeat the steps, sequentially repeating the acquisition step and the adjustment step, until the first temperature data is greater than or equal to the temperature threshold.
[0009] If the first temperature data is greater than or equal to the temperature threshold, the refrigeration equipment is controlled to stop the defrosting operation.
[0010] According to the control method of the refrigeration equipment of this application, after the refrigeration equipment performs the defrosting action according to the first defrosting power for a first target time, the temperature data of the evaporator location is acquired at regular intervals. Based on the changes in the temperature data, the defrosting power of the refrigeration equipment is adjusted. The defrosting power of the refrigeration equipment can be reasonably adjusted according to the defrosting process, thereby reducing unnecessary power consumption, reducing the energy consumption of the refrigeration equipment, and improving the energy-saving effect.
[0011] According to one embodiment of this application, determining the second defrosting power of the refrigeration equipment based on the first temperature data and the second temperature data includes:
[0012] Based on the first temperature data, the second temperature data, the first target time, and the second target time, a first temperature change rate at the location of the evaporator is determined.
[0013] The second defrosting power is determined based on the first temperature change rate.

[0016] Based on the mapping relationship between the temperature change rate table and the defrosting power table, the second defrosting power corresponding to the target temperature change rate is found in the defrosting power table.
[0017] According to one embodiment of this application, the target temperature change rate is equal to the first temperature change rate;
[0018] Alternatively, the target temperature change rate is less than the first temperature change rate, and the target temperature change rate is the temperature change rate with the smallest difference from the first temperature change rate in the temperature change rate table.
[0019] According to one embodiment of this application, the first defrosting power is the maximum defrosting power of the refrigeration device.
[0020] Secondly, this application provides a control device for a refrigeration equipment, the device comprising:
[0021] The acquisition module executes the acquisition step, which is used to acquire the first temperature data of the evaporator location of the refrigeration equipment at the first target time when the duration of the defrosting action performed by the refrigeration equipment according to the first defrosting power reaches the first target duration.
[0022] The first processing module performs an adjustment step to determine whether the first temperature data is less than a temperature threshold. If the first temperature data is less than the temperature threshold, it obtains the second temperature data of the evaporator's location at the second target time, and determines the second defrosting power of the refrigeration equipment based on the first temperature data and the second temperature data, and controls the refrigeration equipment to perform the defrosting action at the second defrosting power.
[0023] The second processing module performs a repeating step, which is used to repeat the acquisition step and the adjustment step in sequence until the first temperature data is greater than or equal to the temperature threshold.
[0024] The third processing module is used to control the refrigeration equipment to stop the defrosting action when the first temperature data is greater than or equal to the temperature threshold.
[0025] According to the control device of the refrigeration equipment of this application, after the refrigeration equipment performs the defrosting action according to the first defrosting power for a first target time, it periodically acquires the temperature data of the evaporator location, and adjusts the defrosting power of the refrigeration equipment according to the changes in the temperature data. It can reasonably adjust the defrosting power of the refrigeration equipment according to the defrosting process, thereby reducing unnecessary power consumption, reducing the energy consumption of the refrigeration equipment, and improving the energy-saving effect.
[0026] Thirdly, this application provides a refrigeration device, which includes:
[0027] Evaporator;
[0028] The sensor module is used to collect the duration of the defrosting action of the refrigeration equipment, the first temperature data of the location of the evaporator at the first target time, and the second temperature data of the location of the evaporator at the second target time.
[0029] The control device for the refrigeration equipment as described in the second aspect above is connected to the sensor module.
[0030] According to the refrigeration equipment of this application, after the refrigeration equipment performs the defrosting action at the first defrosting power for a first target time, it periodically acquires the temperature data of the evaporator location, and adjusts the defrosting power of the refrigeration equipment according to the changes in the temperature data. This allows for reasonable adjustment of the defrosting power of the refrigeration equipment based on the defrosting process, thereby reducing unnecessary power consumption, lowering the energy consumption of the refrigeration equipment, and improving energy-saving effects.

[0046] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0047] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0048] It should be noted that the refrigeration equipment 200 in this embodiment can be understood as a refrigeration storage device in a broad sense, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines. The refrigeration equipment 200 has various structural forms and a wide range of applications.
[0049] In this embodiment, the refrigeration device 200 can be a vending machine. The temperature of the compartment 210 of the vending machine can be below 0 degrees Celsius. In some embodiments, the temperature of the compartment 210 of the vending machine can be from -5°C to -30°C, such as -25°C. The vending machine is used to sell frozen products, such as ice cream and ice cubes.
[0050] The control method, control device, electronic equipment, and readable storage medium of the refrigeration equipment 200 provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.
[0051] The control method of the refrigeration equipment 200 can be applied to the terminal, and can be executed by the hardware or software in the terminal.
[0052] The terminal includes, but is not limited to, a desktop computer. The following embodiments describe a terminal including a display and a touch-sensitive surface. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.
[0053] The control method for the refrigeration device 200 provided in this application embodiment can be executed by an electronic device or a functional module or functional entity in an electronic device that can implement the control method for the refrigeration device 200. The electronic devices mentioned in this application embodiment include, but are not limited to, computers. The control method for the refrigeration device 200 provided in this application embodiment is described below using an electronic device as the execution subject.
[0054] like Figure 2 As shown, the refrigeration equipment 200 provided in this application embodiment includes a compressor (not shown in the figure), an evaporator 220, etc., wherein the compressor drives the refrigeration cycle by compressing the refrigerant, and the evaporator 220 achieves refrigeration by absorbing heat through the evaporation of the refrigerant.
[0055] like Figure 2 As shown, the refrigeration device 200 of this application embodiment has a storage compartment 210, which is a space for storing food and other items that can be refrigerated or frozen.
[0056] The compartment 210 may have an opening for users to access items stored in the compartment 210. The opening of the compartment 210 may be equipped with a door for opening or closing the opening of the compartment 210.
[0057] like Figure 3 As shown, the cold air generated by the evaporator 220 is driven by the fan 230 to flow to the compartment 210, providing cooling capacity to the compartment 210. After passing through the compartment 210, the cold air blows towards the evaporator 220, forming an air circulation. When the humid air comes into contact with the cool surface of the evaporator 220, the water vapor in the air may condense into water droplets or even freeze to form frost.
[0058] The control method for the refrigeration equipment 200 provided in this application embodiment is used to control the refrigeration equipment 200 to perform a defrosting action to melt the frost frozen on the evaporator 220.
[0059] It should be noted that, as Figure 2 As shown, the evaporator 220 of the refrigeration equipment 200 can be equipped with heating devices such as heating wire 240, and the heating wire 240 can be controlled to heat the evaporator 220, thereby achieving defrosting.
[0060] like Figure 1 As shown, the control method of the refrigeration equipment 200 includes steps 110-140.
[0061] Step 110: Acquisition Step. When the duration of the defrosting action performed by the refrigeration equipment 200 according to the first defrosting power reaches the first target duration, the first temperature data of the location of the evaporator 220 of the refrigeration equipment 200 at the first target time is acquired.
[0062] The first target duration is a preset duration, which can be set based on the amount of frost on the evaporator 220 and the humidity of the environment where the refrigeration equipment 200 is located. The first target duration can be set to 3-5 minutes.
[0063] The first defrosting power is the power at which the refrigeration equipment 200 performs the defrosting action. When the refrigeration equipment 200 is operating normally and the defrosting start condition is met, it begins to perform the defrosting action according to the fixed first defrosting power until the duration of the defrosting action according to the first defrosting power reaches the first target duration.
[0064] In actual operation, the defrosting power of the refrigeration equipment 200 can be controlled by controlling the operating rate of the heating wire 240.
[0065] In this embodiment, when the duration of the defrosting action performed by the refrigeration device 200 at a fixed first defrosting power reaches a first target duration, the defrosting power of the refrigeration device 200 can be adjusted to obtain the first temperature data of the location of the evaporator 220 of the refrigeration device 200 at the first target time.
[0066] The first target time is the time after the refrigeration equipment 200 has performed the defrosting action according to the first defrosting power for the duration of the first target time.
[0067] In this embodiment, when the acquisition step is executed for the first time, the first target time can be the time when the refrigeration device 200 starts to perform the defrosting action plus the time corresponding to the first target duration.
[0068] In this embodiment, the first temperature data is the temperature data of the location of the evaporator 220 obtained at the first target time. It can be the temperature data of the cold air flowing from the evaporator 220 to the end of the compartment 210. The first temperature data can be obtained by a temperature sensor.
[0069] Step 120: Adjustment steps, determine whether the first temperature data is less than the temperature threshold, if the first temperature data is less than the temperature threshold, obtain the second temperature data of the location of the evaporator 220 at the second target time, and based on the first temperature data and the second temperature data, determine the second defrosting power of the refrigeration equipment 200, and control the refrigeration equipment 200 to perform the defrosting action with the second defrosting power.
[0070] The temperature threshold is a set value, which can be set based on the amount of frost on the evaporator 220 and the humidity of the environment where the refrigeration equipment 200 is located.
[0071] In this embodiment, after the acquisition step is performed, an adjustment step is performed to determine whether the first temperature data is less than the temperature threshold. If the first temperature data is less than the temperature threshold, the second temperature data of the location of the evaporator 220 at the second target time is acquired.
[0072] In this embodiment, the second target time is the time after the first target time. The second target time can be determined based on the first target time. The second target time can be separated from the first target time by a first time interval. The first time interval is a preset value and can be 10s-30s.
[0073] In this embodiment, the second temperature data is the temperature data of the location of the evaporator 220 at the second target time, and the first temperature data and the second temperature data can be obtained by the same temperature sensor.
[0074] In this embodiment, the second defrosting power is the power of the refrigeration device 200 when performing the defrosting action, and the second defrosting power is less than the first defrosting power.
[0075] In this embodiment, the temperature data change of the evaporator 220 location from the first target time to the second target time can be obtained based on the first temperature data and the second temperature data. The second defrosting power is determined based on the temperature data change. After determining the second defrosting power, the refrigeration equipment 200 is controlled to perform the defrosting action with a second defrosting power that is lower than the first defrosting power, thereby reducing the energy consumption of the refrigeration equipment 200.
[0076] Step 130: Repeat the steps, successively obtaining and adjusting the data until the first temperature data is greater than or equal to the temperature threshold.
[0077] In this embodiment, during the defrosting process of the refrigeration device 200, the acquisition step and the adjustment step are repeated sequentially. Based on the changes in temperature data, a new second defrosting power is continuously determined, and the refrigeration device 200 is continuously adjusted to perform the defrosting action with the new second defrosting power until the first temperature data is greater than or equal to the temperature threshold, at which point the acquisition step and the adjustment step are stopped.
[0078] It is understandable that each execution of the acquisition step corresponds to a first target time, and correspondingly, to a first temperature data at the first target time; each execution of the adjustment step corresponds to a second target time, and correspondingly, to a second temperature data at the second target time; and correspondingly, each execution of the acquisition step and the adjustment step in sequence corresponds to a second defrosting power.
[0079] For example, after the first acquisition step and adjustment step are executed sequentially, the acquisition step is executed a second time to acquire the first temperature data of the location of the evaporator 220 at the second first target time.
[0080] The second first target time can be separated from the first second target time by a second time interval, which is a preset value and can be equal to the first time interval.
[0081] After the second acquisition step, the second adjustment step is performed to determine whether the first temperature data is less than the temperature threshold. If the first temperature data is less than the temperature threshold, the second temperature data of the location of the evaporator 220 at the second second target time is acquired.
[0082] Based on the first temperature data and the second temperature data, a new second defrosting power for the refrigeration equipment 200 is determined, and the refrigeration equipment 200 is controlled to perform the defrosting action with the new second defrosting power.
[0083] In this embodiment, after the acquisition and adjustment steps are executed for the second time, the acquisition and adjustment steps are executed for the third time, and so on, repeating the acquisition and adjustment steps until the first temperature data is greater than or equal to the temperature threshold, at which point the acquisition and adjustment steps are stopped.
[0084] Step 140: If the first temperature data is greater than or equal to the temperature threshold, control the refrigeration equipment 200 to stop the defrosting action.
[0085] In this embodiment, during the process of repeatedly acquiring and adjusting the steps, when the first temperature data acquired at a certain first target time is greater than or equal to the temperature threshold, the acquisition and adjustment steps are stopped, and the refrigeration equipment 200 is controlled to stop defrosting.
[0086] In related technologies, refrigeration equipment 200 typically starts defrosting in the first operating mode. By calculating the time it takes for the evaporator 220 temperature to reach the preset temperature during defrosting, it is determined whether to adopt the second operating mode for defrosting. The defrosting power of the refrigerator is simply adjusted, resulting in poor energy-saving effect.
[0087] In this embodiment, during the initial defrosting phase of the refrigeration equipment 200, defrosting is performed at a first defrosting power. After the duration of defrosting at the first defrosting power reaches a first target duration, temperature data at the location of the evaporator 220 is periodically acquired. Based on the changes in temperature data, the remaining amount of frost on the evaporator 220 is represented, and the defrosting power of the refrigeration equipment 200 is adjusted until the first temperature data is greater than or equal to the temperature threshold. At this point, the refrigeration equipment 200 is controlled to stop defrosting. The defrosting power of the refrigeration equipment 200 can be reasonably adjusted according to the defrosting process, thereby reducing unnecessary power consumption and further reducing the temperature rise of the room 210. This can reduce the energy consumption of the refrigeration equipment 200 and improve energy-saving performance.
[0088] According to the control method of the refrigeration equipment 200 provided in the embodiments of this application, after the refrigeration equipment 200 performs the defrosting action according to the first defrosting power for a period of time until the first target time is reached, the temperature data of the location of the evaporator 220 is acquired at regular intervals. Based on the changes in the temperature data, the defrosting power of the refrigeration equipment 200 is adjusted. The defrosting power of the refrigeration equipment 200 can be reasonably adjusted according to the defrosting process of the refrigeration equipment 200, thereby reducing useless power consumption, reducing the energy consumption of the refrigeration equipment 200, and improving the energy-saving effect.
[0089] In some embodiments, determining the second defrosting power of the refrigeration device 200 based on first temperature data and second temperature data includes:
[0090] Based on the first temperature data, the second temperature data, the first target time, and the second target time, determine the first temperature change rate at the location of the evaporator 220;
[0091] The second defrosting power is determined based on the first temperature change rate.
[0092] Among them, the first temperature change rate can characterize the rate of temperature change of the refrigeration equipment 200.
[0093] In this embodiment, the first temperature change rate can be the second temperature data minus the ratio of the first temperature data to the second target time minus the first target time.
[0094] For example, the second temperature data is T2, the first temperature data is T1, the second target time is t2, the first target time is t1, and the first temperature change rate S = (T2-T1) / (t2-t1).
[0095] In this embodiment, first temperature data of the location of evaporator 220 is acquired at a first target time, and second temperature data of the location of evaporator 220 is acquired at a second target time. The first temperature change rate is calculated by the difference between the second temperature data and the first temperature data, and the time interval between the second target time and the first target time. The second defrosting power corresponding to the first temperature change rate is determined, and the refrigeration equipment 200 is controlled to perform defrosting action with the second defrosting power.
[0096] In some embodiments, determining the second defrosting power based on the first temperature change rate includes:
[0097] Find the target temperature change rate corresponding to the first temperature change rate in the temperature change rate table;
[0098] Based on the mapping relationship between the temperature change rate table and the defrosting power table, the second defrosting power corresponding to the target temperature change rate is found in the defrosting power table.
[0099] The table of temperature change rates includes multiple temperature change rates.
[0100] In this embodiment, the first temperature change rate can be compared with the temperature change rates in the temperature change rate table. Based on the comparison results between the first temperature change rate and each temperature change rate in the temperature change rate table, the target temperature change rate corresponding to the first temperature change rate can be determined in the temperature change rate table.
[0101] In this embodiment, the defrosting power table is a table that includes multiple defrosting powers.
[0102] In this embodiment, the temperature change rate in the temperature change rate table can correspond one-to-one with the defrosting power in the defrosting power table. The mapping relationship between the temperature change rate table and the defrosting power table can characterize the one-to-one correspondence between the temperature change rate in the temperature change rate table and the defrosting power in the defrosting power table.
[0103] In this embodiment, after determining the target temperature change rate, the defrosting power corresponding to the target temperature change rate can be found in the defrosting power table according to the mapping relationship between the temperature change rate table and the defrosting power table, and used as the second defrosting power.
[0104] In some embodiments, the target temperature change rate is equal to the first temperature change rate;
[0105] Alternatively, the target temperature change rate is less than the first temperature change rate, and the target temperature change rate is the temperature change rate with the smallest difference from the first temperature change rate in the temperature change rate table.
[0106] In this embodiment, when a temperature change rate equal to the first temperature change rate exists in the temperature change rate table, the temperature change rate equal to the first temperature change rate is determined as the target temperature change rate.
[0107] If there is no temperature change rate in the temperature change rate table that is equal to the first temperature change rate, the temperature change rate that is less than the target temperature change rate and has the smallest difference from the first temperature change rate in the temperature change rate table will be determined as the target temperature change rate.
[0108] In some embodiments, the first defrosting power is the maximum defrosting power of the refrigeration device 200.
[0109] In this embodiment, during the initial defrosting stage of the refrigeration equipment 200, there is a large amount of ice on the evaporator 220, which can supply power to the heating wire 240 at 100% operating rate to ensure maximum defrosting power and ensure rapid defrosting.
[0110] Table 1
[0111] Temperature change rate numerical values S1 1℃ / min S2 2℃ / min S3 3℃ / min S4 4℃ / min S5 5℃ / min S6 6℃ / min S7 7℃ / min S8 8℃ / min S9 9℃ / min S10 10℃ / min
[0112] The following is a specific embodiment of a control method for a refrigeration device 200.
[0113] like Figure 6 As shown, in step one, after the refrigeration equipment 200 is running normally and the defrosting start conditions are met, it starts to supply power to the heating wire 240 at the maximum start rate h1 in Table 2, that is, 100% start rate, and sets the first target duration t0, which can be 3min-5min.
[0114] Step 2: Set the first time interval to 10s and the second time interval to 10s. After the heating wire 240 is powered at 100% power and the heating time reaches the first target duration t0, start timing the first target time t1 and acquire the first temperature data T1 at the first target time.
[0115] Step 3: Determine whether the first temperature data T1 has reached the set temperature threshold T0. If the first temperature data T1 has reached the set temperature threshold T0, control the refrigeration equipment 200 to stop defrosting. If the first temperature data T1 has not reached the set temperature threshold T0, proceed to the next step.
[0116] Step 4: After the first time interval is 10s, time the second target time t2, and obtain the second temperature data T2 at the second target time. Calculate the first temperature change rate S = (T2-T1) / (t2-t1).
[0117] Step 5: Find the target temperature change rate corresponding to the first temperature change rate in the temperature change rate table in Table 1. Let Sn < S < Sn+1, determine Sn as the target temperature change rate, and derive the value of n.
[0118] Step 6: Find the second defrosting power corresponding to the target temperature change rate in the defrosting power table in Table 2, that is, adjust the heating wire 240 to operate at the hn operating rate.
[0119] Step 7: Collect temperature data again and continuously adjust the on-time of heating wire 240 until the first temperature data reaches the temperature threshold T0.

[0122] In related technologies, such as Figure 4 As shown, the horizontal axis represents the defrosting time, and the vertical axis represents the temperature of the evaporator 220. The refrigeration equipment 200 defrosts with a fixed defrosting power. As the defrosting time increases, the temperature of the evaporator 220 gradually rises faster. After reaching the temperature threshold T0, defrosting stops, resulting in high power consumption and incomplete defrosting.
[0123] In the embodiments of this application, such as Figure 5 As shown, the horizontal axis represents the defrosting time, and the vertical axis represents the temperature of the evaporator 220. During the start-up phase, that is, within the time t0 when the refrigeration equipment 200 begins to perform the defrosting action, the refrigeration equipment 200 performs the defrosting action with a fixed defrosting power. After the time t0, the defrosting power of the refrigeration equipment 200 is adjusted according to the changes in the temperature data of the evaporator 220. The defrosting power is intelligently controlled, and the temperature rise rate of the evaporator 220 is more gradual, which can fully defrost while reducing power loss.
[0124] The control method for the refrigeration equipment 200 provided in this application embodiment can be executed by the control device of the refrigeration equipment 200. This application embodiment uses the control device of the refrigeration equipment 200 executing the control method as an example to illustrate the control device of the refrigeration equipment 200 provided in this application embodiment.
[0125] This application also provides a control device for a refrigeration device 200.
[0126] like Figure 7 As shown, the control device of the refrigeration equipment 200 includes:
[0127] The acquisition module 710 executes the acquisition step, which is used to acquire the first temperature data of the location of the evaporator 220 of the refrigeration equipment 200 at the first target time when the duration of the defrosting action performed by the refrigeration equipment 200 according to the first defrosting power reaches the first target duration.
