Abstract
Description
Technical Field
[0001] This application belongs to the field of refrigeration equipment technology, and particularly relates to a control method, device and refrigeration equipment for refrigeration equipment. Background Technology
[0002] During the operation of refrigeration equipment, due to prolonged exposure to low temperatures, internal components such as the evaporator may frost or even ice up. If these frost or ice formations are not addressed promptly, the increasingly thick frost layer will interfere with heat exchange efficiency, thereby reducing the cooling performance of the refrigeration system. Furthermore, frost can damage the internal structure of the equipment. Therefore, it is necessary to assess the refrigeration equipment for defrosting and perform defrosting operations as needed.
[0003] Currently, a fixed defrosting judgment method is usually used for defrosting judgment. If the defrosting judgment method is abnormal, continuing to perform defrosting judgment will lead to the refrigeration equipment performing defrosting at an inappropriate time, resulting in insufficient defrosting or excessive defrosting.

[0048] The capacitor structure is 410, the first plate is 411, and the power supply is 420. Detailed Implementation
[0049] 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.
[0050] 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.
[0051] The control method, control device, refrigeration equipment 200, 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.
[0052] 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.
[0053] The terminal includes, but is not limited to, portable communication devices such as mobile phones or tablets with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads). It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads).
[0054] 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.
[0055] 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.
[0056] like Figure 2 As shown, the refrigeration device 200 of 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.
[0057] 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.
[0058] The storage room 210 may have an opening for users to access items stored in the storage room 210. The opening of the storage room 210 may be equipped with a door for opening or closing the opening of the storage room 210.
[0059] Understandably, when the door is closed, the storage room 210 is a sealed space that can isolate the refrigeration equipment 200 from the external environment.
[0060] like Figure 3 As shown, the cold air generated by the evaporator 220 is driven by the fan 230 to flow to the storage compartment 210, providing cooling capacity to the storage compartment 210. After passing through the storage 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.
[0061] The control method of the refrigeration equipment 200 in this application embodiment is used to determine the defrosting mode in which the refrigeration equipment 200 performs defrosting action to defrost the evaporator 220.
[0062] The defrosting mode represents the way the refrigeration equipment 200 makes a defrosting judgment, that is, the way to judge whether the refrigeration equipment 200 needs to defrost. For example, the defrosting mode may include making a defrosting judgment based on the running time of the refrigeration equipment 200, making a defrosting judgment based on the ambient humidity and temperature of the refrigeration equipment 200, and making a defrosting judgment based on the compressor operating status of the refrigeration equipment 200.
[0063] like Figure 1 As shown, the control method of the refrigeration equipment 200 includes steps 110, 120 and 130.
[0064] Step 110: Obtain the first defrost count of the refrigeration equipment 200 within the target time period.
[0065] The target time period can be the time period ending when the refrigeration equipment 200 stops defrosting. The duration of the target time period can be preset, such as 12 hours or 24 hours. The first defrosting count is the number of times the refrigeration equipment 200 performs the defrosting action within the target time period.
[0066] In this embodiment, the first defrosting count of the refrigeration equipment 200 within the target time period can be obtained by reading the monitoring system or log records of the refrigeration equipment 200.
[0067] Step 120: Compare the first number of defrost cycles with the preset number of defrost cycles to obtain the first comparison result.
[0068] The preset defrost count range is a pre-set range. The minimum value of the preset defrost count range can represent the number of times the refrigeration equipment 200 performs defrost action under normal circumstances within the target time period. The preset defrost count range and the duration of the target time period can be set according to the humidity of the environment where the refrigeration equipment 200 is located.
[0069] For example, if the average humidity of the environment during the target period is 60%-80% and the duration of the target period is 12 hours, the preset number of defrost cycles is 2 to 5. If the ambient humidity is less than 20%, the environment is considered to be relatively dry. If the duration of the target period is 24 hours, the preset number of defrost cycles is 1 to 3.
[0070] In this embodiment, the first number of defrost cycles is compared with two boundary values of a preset defrost cycle range to obtain a first comparison result. The first comparison result may include the first number of defrost cycles being less than the minimum value of the preset defrost cycle range, the first number of defrost cycles being equal to the minimum value of the preset defrost cycle range, the first number of defrost cycles being within the preset defrost cycle range, the first number of defrost cycles being greater than the maximum value of the preset defrost cycle range, and the first number of defrost cycles being equal to the maximum value of the preset defrost cycle range.
[0071] Step 130: Based on the first comparison result, determine the defrosting mode of the refrigeration equipment 200 after the target time period.
[0072] In this embodiment, the appropriateness of the current defrosting mode is determined based on the first comparison result. If the current defrosting mode is appropriate or the judgment logic is normal, the current defrosting mode is maintained. If the current defrosting mode is inappropriate or the judgment logic is abnormal, the current defrosting mode is adjusted or another defrosting mode is used.
[0073] After determining the defrosting mode, a defrosting judgment is made based on the determined defrosting mode.
[0074] According to the control method of the refrigeration equipment 200 provided in the embodiments of this application, the defrosting mode of the refrigeration equipment 200 after the target time period is determined by comparing the first defrosting number of the refrigeration equipment 200 within the target time period with the first comparison result of the preset defrosting number range. When the current defrosting mode is not suitable or an abnormality occurs, the current defrosting mode can be adjusted or other defrosting modes can be used to ensure that the refrigeration equipment 200 defrosts at the appropriate time and reduce the defrosting of the refrigeration equipment 200 being insufficient or excessive.
[0075] In some embodiments, determining the defrosting mode of the refrigeration device 200 after a target time period based on the first comparison result includes:
[0076] If the number of defrost cycles is less than the first boundary value, obtain the ambient humidity information of the refrigeration equipment 200 during the target time period;
[0077] Based on the ambient humidity information, the defrosting mode of the refrigeration equipment 200 after the target time period is determined.
[0078] The first boundary value is the minimum value within the preset range of defrosting times.
[0079] The ambient humidity information is the humidity information of the environment in which the refrigeration equipment 200 is located during the target time period. It can be the average ambient humidity during the target time period. A humidity sensor can be set to obtain the ambient humidity information.
[0080] In this embodiment, when the first number of defrost cycles is less than the first boundary value, the ambient humidity information can be compared with the set humidity value, and the defrosting mode of the refrigeration equipment 200 after the target time period can be determined based on the humidity comparison result.
[0081] In some embodiments, the refrigeration device 200 includes an evaporator 220, which forms a capacitor structure 410 with a first electrode plate 411. The capacitor structure 410 is periodically charged and discharged between a first voltage and a second voltage. Based on ambient humidity information, the defrosting mode of the refrigeration device 200 after a target time period is determined, including:
[0082] If the ambient humidity information is lower than the preset ambient humidity, the defrosting mode of the refrigeration equipment 200 after the target time period is determined to be the first mode.
[0083] The first mode is a defrosting determination mode based on the time it takes for the capacitor structure 410 to charge from the first voltage to the second voltage.
[0084] like Figure 4 As shown, the evaporator 220 and the first electrode plate 411 form a capacitor structure 410. The first electrode plate 411 is connected to the power supply 420, and the evaporator 220 is grounded.
[0085] In this embodiment, the first electrode plate 411 is a flat plate made of a material with good conductivity, such as metal and graphene, and the capacitor structure 410 is an electrical component that can store and release charge.
[0086] A periodic square wave signal can be sent to the capacitor structure 410 through the internal power supply 420 of the cooling device 200 or the external power supply 420. Within one square wave signal cycle, the capacitor structure 410 starts charging when the square wave signal is high and starts discharging when the square wave signal is low. The capacitor structure 410 is periodically charged and discharged between the first voltage and the second voltage.
[0087] The first voltage can be the voltage when the capacitor structure 410 is fully discharged, i.e., the first voltage can be 0. The second voltage is the stable voltage of the capacitor structure 410 after it is fully charged.
[0088] like Figure 5 As shown, the first mode includes:
[0089] Step 510: Obtain the first duration for the capacitor structure 410 to charge from the first voltage to the second voltage.
[0090] Step 520: If the first duration is greater than or equal to the preset duration threshold, control the refrigeration equipment 200 to perform the defrosting action.
[0091] In this embodiment, the cooling device 200 acquires the first duration of the capacitor structure 410 charging from the first voltage to the second voltage in the first mode. The capacitor structure 410 can be connected to a timer, which is used to record the first duration of the capacitor structure 410 charging from the first voltage to the second voltage each time during the periodic charging and discharging process of the capacitor structure 410.
[0092] When the first duration is greater than or equal to the preset duration threshold, the refrigeration equipment 200 is controlled to perform a defrosting action. The preset duration threshold is a preset value. An initial preset duration threshold can be set when the refrigeration equipment 200 leaves the factory. The initial preset duration threshold can be set according to the design parameters of the refrigeration equipment 200 and the operating environment that the refrigeration equipment 200 is adapted to.
[0093] In this embodiment, the larger the capacitance value of the capacitor structure 410, the longer it takes for the capacitor structure 410 to charge an equal amount of power. The capacitance value of the capacitor structure 410 can be determined based on the time it takes for the capacitor structure 410 to charge or discharge the corresponding amount of power.
[0094] According to the formula for calculating the capacitance of a parallel plate When air is used as the dielectric, the formula for calculating capacitance is as follows: When ice is used as the dielectric, the formula for calculating capacitance is as follows: When ice forms between the plates of capacitor structure 410, the capacitance value will increase significantly, resulting in a longer first duration corresponding to capacitor structure 410.
[0095] In this step, when the first duration is greater than or equal to the preset duration threshold, it indicates that there is a lot of frost on the evaporator 220, and the refrigeration equipment 200 is controlled to perform a defrosting action to defrost the evaporator 220.
[0096] In this embodiment, such as Figure 2 As shown, the evaporator 220 of the refrigeration equipment 200 can be equipped with heating devices 240 such as heating tubes. The heating tubes can be controlled to heat the evaporator 220, thereby achieving defrosting. The heating tubes can be defrosting heating steel tubes or defrosting heating aluminum tubes.
[0097] Alternatively, an electric valve can be installed at the discharge end of the compressor. When the refrigeration equipment 200 performs the defrosting action, the electric valve is controlled to open, and the hot gas discharged from the compressor passes through the evaporator 220 to defrost the evaporator 220.
[0098] In this embodiment, the defrosting mode of the refrigeration device 200 during the target time period can be the first mode, that is, when the refrigeration device 200 performs defrosting judgment in the first mode, the defrosting mode of the refrigeration device 200 after the target time period is determined based on the first comparison result.
[0099] In this embodiment, when the first defrosting count is less than the first boundary value and the ambient humidity information is less than the preset ambient humidity, it indicates that the current first mode of the refrigeration device 200 is not abnormal, and the refrigeration device 200 performs defrosting judgment in the first mode after the target time period.
[0100] In some embodiments, determining the defrosting mode of the cooling device 200 after a target time period based on ambient humidity information includes:
[0101] When the ambient humidity information is greater than or equal to the preset ambient humidity, the defrosting mode of the refrigeration equipment 200 after the target time period is determined to be the second mode, which is the mode that performs the defrosting action according to the preset time interval.
[0102] The preset time interval is a pre-defined time interval that can be set based on the humidity, temperature, and other environmental factors of the environment in which the refrigeration equipment 200 is located.
[0103] In this embodiment, when the first defrosting count is less than the first boundary value and the ambient humidity information is greater than or equal to the preset ambient humidity, it indicates that the first mode of the refrigeration device 200 is abnormal. After the target time period, the refrigeration device 200 performs defrosting judgment in the second mode, that is, it judges whether the time elapsed since the last defrosting action has reached the preset time interval. If the preset time interval has been reached, the refrigeration device 200 is controlled to perform the defrosting action.
[0104] In some embodiments, the refrigeration device 200 includes an evaporator 220, which forms a capacitor structure 410 with a first electrode plate 411. The capacitor structure 410 is periodically charged and discharged between a first voltage and a second voltage. Based on a first comparison result, a defrosting mode of the refrigeration device 200 after a target time period is determined, including:
[0105] If the number of defrost cycles is within the preset number of defrost cycles, the defrosting mode of the refrigeration equipment 200 after the target time period is determined as the first mode. The first mode is a defrosting judgment based on the time it takes for the capacitor structure 410 to charge from the first voltage to the second voltage.
[0106] In this embodiment, if the first defrost count is greater than the minimum value of the preset defrost count range but less than the maximum value of the preset defrost count range, the refrigeration equipment 200 will perform defrosting judgment in the first mode after the target time period.
[0107] In some embodiments, determining the defrosting mode of the refrigeration device 200 after a target time period as a first mode includes:
[0108] The defrosting mode of the refrigeration equipment 200 after the target time period is determined as the first mode, and the duration of the next defrosting action of the refrigeration equipment 200 is increased.
[0109] In this embodiment, if the first defrost count is greater than the minimum value of the preset defrost count range and less than the maximum value of the preset defrost count range, it indicates that there is no abnormality in the current first mode, but the defrosting action of the refrigeration equipment 200 is insufficient, and the defrosting time will be increased when the refrigeration equipment 200 performs the defrosting action next time.
[0110] In some embodiments, determining the defrosting mode of the refrigeration device 200 after a target time period based on the first comparison result includes:
[0111] If the first defrosting count is greater than or equal to the second boundary value, the defrosting mode of the refrigeration equipment 200 after the target time period is determined to be the second mode, which is the mode of performing defrosting actions according to a preset time interval.
[0112] The second boundary value is the maximum value within the preset range of defrosting times.
[0113] In this embodiment, if the first defrosting count is greater than or equal to the second boundary value, it indicates that the first mode of the refrigeration device 200 is abnormal, and the refrigeration device 200 will perform defrosting judgment according to the second mode after the target time period.
[0114] In some embodiments, the refrigeration device 200 includes an evaporator 220, which forms a capacitor structure 410 with a first electrode plate 411. The capacitor structure 410 is periodically charged and discharged between a first voltage and a second voltage. Based on a first comparison result, a defrosting mode of the refrigeration device 200 after a target time period is determined, including:
[0115] When the first number of defrost cycles equals the first boundary value, the defrosting mode of the refrigeration equipment 200 after the target time period is determined as the first mode. The first mode is a defrosting judgment based on the time it takes for the capacitor structure 410 to charge from the first voltage to the second voltage.
[0116] In this embodiment, the first defrosting count being equal to the first boundary value indicates that the refrigeration equipment 200 has not encountered any abnormalities in defrosting according to the first mode, and the refrigeration equipment 200 continues to defrost according to the first mode after the target time period.
[0117] The following is a specific embodiment of a control method for a refrigeration device 200.
[0118] like Figure 6 As shown, in step one, the cooling device 200 is detected to be powered on, and the positive power supply 420 voltage Vcc begins to send a set square wave signal to the capacitor structure 410. At the same time, the analog-to-digital converter A / D port of the control chip begins to detect the voltage of the capacitor structure 410.
[0119] Step 2: Record the first time t of the capacitor structure 410 rising from the first voltage 0 to the second voltage Vc.
[0120] Step 3: Determine whether t is greater than or equal to the preset time threshold T, where T = T1 + T2, T1 is the factory charging time of capacitor structure 410, and T2 is the first preset time. The first preset time represents the charging time that increases when the refrigeration equipment 200 frosts to a certain extent.
[0121] The factory charging time can be the time it takes for the capacitor structure 410 of the refrigeration equipment 200 to charge from the first voltage to the second voltage when it leaves the factory.
[0122] Step 4: When t is greater than or equal to T, turn off Vcc, turn on the defrosting heating wire, and control the refrigeration equipment 200 to perform the defrosting action according to the first target duration, where the first target duration is a preset duration.
[0123] Step 5: After defrosting is complete, continue to turn on Vcc to detect the amount of frost, and at the same time record the number of defrost cycles within the target time period plus 1.
[0124] Step 6: Determine whether the number of defrosting actions performed within the target time period is greater than the target number of defrosting actions, i.e. whether it is greater than the first boundary value, within the preset number of defrosting actions.
[0125] Step 7: Check if the number of defrosting actions performed within the target time period is greater than the target number of defrosting actions. If it is within the preset number of defrosting actions, the next time the defrosting action is performed, the duration will be increased by 50% based on the first target duration.
[0126] Step 8: Immediately detect the second time T0 of the capacitor structure 410 charging from the first voltage to the second voltage, and determine whether T0 is greater than or equal to T1.
