Description

Technical Field

[0001] This application relates to the field of refrigerators, and in particular to a refrigeration control method, a refrigeration system, and a readable storage medium. Background Technology

[0002] Currently, there are many types of refrigerators available. Multi-temperature zone refrigerators offer more space and allow for categorized storage of items, making them popular with consumers. However, more temperature zones result in larger refrigerators that occupy more space. Therefore, integrated home appliances are gradually becoming a development trend. Integrated home appliances combine the refrigerator with the furniture, increasing the utilization of room space. However, in this hybrid setup, simultaneously controlling the temperature of each zone increases energy consumption, leading to higher electricity bills. Summary of the Invention

[0018] Determine the demand range within which the total cooling demand falls;

[0019] The operating frequency corresponding to the demand range is found in the frequency operation mapping table, and the operating frequency is used as the operating frequency of the compressor.

[0020] In the above technical solution, an appropriate operating frequency is selected as the compressor's operating frequency based on the demand range of the total cooling demand, thereby reducing energy consumption and saving electricity.

[0021] In some embodiments of this application, the state parameters include the set temperature, the current temperature, and the volume of the refrigerator compartments;

[0026] In some embodiments of this application, determining the target refrigerator unit based on the cooling demand corresponding to each of the refrigerator units includes:

[0027] If the cooling demand is not zero, the refrigerator unit corresponding to the cooling demand is identified as the target refrigerator unit.

[0028] In the above technical solution, when the cooling demand is not zero, the refrigerator unit is indicated to require cooling control, which can accurately identify the refrigerator unit that needs cooling, thereby achieving precise control.

[0033] The total cooling demand is obtained by weighted summation of the cooling demand corresponding to each of the target refrigerator units.

[0034] In the above technical solution, the weighted summation coefficient affects the total cooling demand in the weighted summation calculation, which in turn affects the operating frequency of the compressor, thereby determining an appropriate operating frequency to achieve the effect of saving electricity.

[0037] In the above technical solution, each refrigerator unit is polled, and the output pipeline is connected to the target refrigerator unit through an electric switching valve, thereby achieving accurate control of each refrigerator unit.

[0038] In some embodiments of this application, after the compressor is turned on and the electric switching valve is connected to the output pipeline corresponding to the target refrigerator unit, and before the operating frequency of the compressor is controlled according to the cooling demand corresponding to each target refrigerator unit, the cooling control method further includes:

[0039] When the current temperature of the target refrigerator unit reaches the preset shutdown temperature, the electric switching valve is controlled to point to the next refrigerator unit.

[0040] In the above technical solution, when the current temperature is equal to the preset shutdown temperature, the electric switching valve points to the next refrigerator unit, the cooling ends, the total cooling demand is recalculated, and the compressor's operating frequency is re-determined so that the compressor always operates at the optimal frequency, thereby achieving the purpose of saving electricity.

[0055] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various implementations. Simultaneously, the steps or actions described in the method description can be rearranged or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various orders in the specification and drawings are merely for the clear description of a particular embodiment and do not imply a mandatory order, unless otherwise stated that a particular order must be followed.

The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0058] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0059] In related technologies, multi-temperature zone refrigerators that integrate home appliances typically use multiple solenoid valves to control each temperature zone, with one valve controlling one temperature zone. Precise temperature control is achieved through specific solenoid valves controlling the temperature of the controlled zone. However, in some refrigerators with separate cooling units, where the cooling demand is low or no cooling is required, multiple temperature zones operate at a fixed compressor frequency, leading to wasted electricity.

[0060] Based on the above, this application provides a refrigeration control method, a refrigeration system, and a readable storage medium. By acquiring the state parameters of each refrigerator unit and determining the refrigeration demand of each unit based on these parameters, a target refrigerator unit is identified based on its refrigeration demand. The compressor is then activated, and an electric switching valve is controlled to connect the output pipeline corresponding to the target refrigerator unit. This allows for precise control of the target refrigerator unit, achieving centralized refrigeration and distributed cooling. Furthermore, the operating frequency of the compressor is controlled according to the refrigeration demand of each target refrigerator unit, ensuring the compressor operates at an appropriate frequency and thus saving electricity. This refrigeration control method can be applied to the refrigeration of cabinet-type refrigerators, achieving integrated control of cabinet refrigerators; it can also be applied to the refrigeration of storage cabinet refrigerators in halls or rooms, achieving integrated control of cabinet furniture and refrigerators; and it can also be applied to temperature control in other distributed installation design modes for refrigerator units, making it widely applicable.

[0061] The embodiments of the refrigeration control method provided in this application will be further described below with reference to the accompanying drawings.

[0062] like Figure 1 As shown, Figure 1 This is a flowchart of a refrigeration control method provided in one embodiment of this application. The refrigeration control method of this embodiment is applied to a refrigeration system, which includes a refrigeration unit and multiple refrigerator units. The refrigeration unit includes a compressor, which is connected to multiple output pipes through an electric switching valve. Each output pipe is connected to one refrigerator unit. The refrigeration control method includes, but is not limited to, steps S100, S200, S300, S400, and S500.

[0063] Step S100: Obtain the state parameters corresponding to each refrigerator unit.

[0064] In one embodiment, the refrigerator compartment can be either a freezer or a refrigerator compartment. Each refrigerator compartment is equipped with a sensor to obtain the corresponding status parameters of the freezer and refrigerator compartments. The sensors communicate with the refrigeration unit. The sensors include a temperature sensor and a diameter sensor. The temperature sensor measures the temperature of the refrigerator compartment, including the current temperature, a preset shutdown temperature, or a set temperature. The diameter sensor measures the volume of the refrigerator compartment and can also count the number of refrigerator compartments. Therefore, the status parameters include the set temperature, the current temperature, the volume of each refrigerator compartment, and the number of refrigerator compartments. Obtaining the status parameters corresponding to each refrigerator compartment is beneficial for subsequently determining whether each refrigerator compartment has a cooling requirement.

[0065] Step S200: Determine the cooling demand of each refrigerator unit based on the status parameters of each refrigerator unit.

[0066] In one embodiment, based on the state parameters obtained through communication, these state parameters are substituted into preset arithmetic rules for calculation to obtain the cooling demand corresponding to the refrigerator unit. By determining the cooling demand, it is possible to determine which refrigerator units need cooling and which do not. Determining the cooling demand of each refrigerator unit is beneficial for adjusting the operating frequency of the compressor according to the operating status of each refrigerator unit, thereby achieving energy saving.

[0067] like Figure 4 As shown, based on the status parameters of each refrigerator unit, the cooling demand of each refrigerator unit is determined, including but not limited to the following steps:

[0068] Step S210: For each refrigerator unit, calculate the difference between the current temperature and the set temperature to obtain the temperature difference;

[0069] In one specific embodiment, the current temperature and the set temperature parameters are substituted into an arithmetic formula to first calculate the difference between the current temperature and the set temperature. This temperature difference facilitates the subsequent calculation of cooling demand. Generally, the current temperature is higher than the set temperature. Therefore, in the calculation, the current temperature is subtracted from the set temperature, resulting in a temperature difference that is not less than zero. Alternatively, the set temperature can be subtracted from the current temperature, resulting in a temperature difference that is less than zero. A value less than zero indicates that the temperature is below zero. In the subsequent calculation of cooling demand, the sign is ignored, and the numerical value is used directly. This ensures that the calculated cooling capacity is not less than zero, making it easier to determine if there is a cooling demand. For each refrigerator unit, to ensure that the calculated result is not less than zero, the above temperature difference calculation can be expressed by the following formula:

[0070] ΔT=|T xi -T yi |

[0071] Where ΔT represents the temperature difference, T xi The i-th refrigerator unit represents the current temperature, T. yi This represents the set temperature of the i-th refrigerator unit.

[0072] Step S220: Multiply the temperature difference and the volume of the refrigerator compartments to obtain the cooling demand.

[0073] In one specific embodiment, based on the temperature difference calculated in step S210, the temperature difference and the volume of each refrigerator unit are substituted into an arithmetic rule to calculate the cooling demand of each refrigerator unit, which is expressed by the formula S. i =V i *ΔT, where S i V represents the cooling demand of the i-th refrigerator unit. iLet represent the volume of the i-th refrigerator unit, and ΔT represent the temperature difference.

[0074] For example, the cooling demand calculated based on the set temperature, current temperature, and refrigerator compartment volume is shown in the table below:

[0075]

[0076] Step S300: Determine the target refrigerator unit based on the cooling demand corresponding to each refrigerator unit, wherein the target refrigerator unit refers to the refrigerator unit with cooling demand.

[0077] In one embodiment, step S200 calculates the cooling demand of each refrigerator unit. Since the values ​​of the cooling demand are all not less than zero, if the cooling demand is not zero or is greater than zero, it means that the current temperature in the refrigerator unit is greater than the set temperature. At this time, the refrigerator unit is determined to need cooling, and the refrigerator unit is determined as the target refrigerator unit. The cooling demand is saved, which is beneficial for subsequent calculations to determine the appropriate compressor operating frequency, thereby achieving the effect of saving electricity.

[0078] In another embodiment, after determining the cooling demand of each refrigerator unit according to the state parameters corresponding to each refrigerator unit, the cooling control method further includes: calculating the cooling demand of each refrigerator unit according to step S200. Since the values ​​of the above cooling demand are all not less than zero, when the cooling demand of each refrigerator unit is zero, it means that the current temperature in the corresponding refrigerator unit is equal to the set temperature, or the current temperature in the corresponding refrigerator unit is equal to the preset shutdown temperature. At this time, the refrigerator unit is determined to not need cooling, and the compressor is stopped to save electricity.

[0079] Step S400: Turn on the compressor and control the electric conversion valve to connect the output pipe corresponding to the target refrigerator unit.

[0080] In one embodiment, the cooling demand is obtained based on the acquired state parameters. This allows for the determination of which refrigerator units require cooling and which do not. The compressor and electric switching valve are then activated. Since the output pipe of the electric switching valve corresponds to the refrigerator unit, the target refrigerator unit is identified in step S300. The electric switching valve is then adjusted to connect its output pipe to the corresponding target refrigerator unit, thereby achieving precise temperature control for each refrigerator unit. This also facilitates the subsequent calculation of the total cooling demand based on the cooling demand of the target refrigerator unit, allowing for the setting of an appropriate compressor operating efficiency.

[0081] In one specific embodiment, the compressor is turned on, and the electric switching valve is controlled to poll each refrigerator unit. If the current refrigerator unit does not need cooling, or if the detected cooling demand is zero, the refrigerator unit is not connected to the output pipe of the electric switching valve. If the currently polled refrigerator unit is the target refrigerator unit, the electric switching valve is controlled to connect the output pipe corresponding to the target refrigerator unit, and cooling control is performed on the target refrigerator unit. By polling each refrigerator unit, accurate control of each refrigerator unit is achieved, and the polling time is short, completing the query within a few seconds.

[0082] In one embodiment, after the compressor is turned on and the electric switching valve is connected to the output pipe corresponding to the target refrigerator unit, before controlling the compressor's operating frequency according to the cooling demand of each target refrigerator unit, each refrigerator unit is polled via the electric switching valve. When a target refrigerator unit is polled, cooling is applied to that unit. Once the current temperature reaches the preset shutdown temperature, cooling is complete, and the electric switching valve is then controlled to move to the next refrigerator unit for cooling. The shutdown temperature can be a set temperature or a suitable operating temperature. It should be noted that after cooling is complete for the target refrigerator unit and the electric switching valve moves to the next refrigerator unit, the total cooling demand decreases, and the compressor's operating frequency, determined based on the total cooling demand, decreases, thereby saving energy.

[0083] In another embodiment, the electric switching valve polls each refrigerator unit. First, it determines the initial refrigerator unit to be queried. This can be done through a random algorithm or based on the cooling demand of each target refrigerator unit. Specifically, determining the initial query point based on the cooling demand of each target refrigerator unit involves sorting the cooling demands stored in the communication database and selecting the target refrigerator unit with the largest or smallest cooling demand as the initial query unit. When cooling is performed on the target refrigerator unit with the largest cooling demand, the total cooling demand will decrease significantly after cooling is complete, and the compressor's operating frequency will be reduced to save power. When cooling is performed on the target refrigerator unit with the smallest cooling demand, the total cooling demand will also decrease after cooling is complete, and the compressor's operating frequency will be maintained or reduced based on the total cooling demand to save power.

[0084] Step S500: Control the operating frequency of the compressor according to the cooling demand of each target refrigerator unit.

[0085] In another embodiment, the cooling demand of each refrigerator unit is obtained according to steps S100 to S400. It should be noted that the cooling demand of a refrigerator unit with no cooling demand is zero, and it has little impact on the compressor's operating frequency. Based on the cooling demand of each target refrigerator unit, when the cooling control of one target refrigerator unit is completed, the cooling of one target refrigerator unit is reduced, and the total cooling demand decreases. Therefore, the compressor's operating frequency is adjusted to decrease or remain constant. Conversely, when a refrigerator unit that does not require cooling becomes a target refrigerator unit, the total cooling demand increases. Therefore, the compressor's operating frequency is adjusted to increase or remain constant. These adjustments ensure the compressor operates at a suitable frequency, thereby saving electricity. Adjusting the compressor's operating frequency involves adjusting the compressor's rotational speed, which directly reflects the compressor's operating status.

[0086] like Figure 2 As shown, the compressor's operating frequency is controlled according to the cooling demand of each target refrigerator unit, including but not limited to the following steps:

[0087] Step S510: Calculate the total cooling demand based on the cooling demand of each target refrigerator unit.

[0088] In one embodiment, the cooling requirements of each target refrigerator unit are added together to obtain the total cooling requirement. This total cooling requirement allows for adjusting the compressor's operating frequency, thus saving electricity. The formula for calculating the total cooling requirement based on the individual cooling requirements is as follows: Among them, S i Let S represent the cooling demand of the i-th refrigerator unit, S represent the total cooling demand, and n represent the number of target refrigerator units. In another embodiment, the cooling demand of each target refrigerator unit is weighted and summed, i.e., a correlation coefficient is set for each target refrigerator unit to obtain the total cooling demand. This ensures that the total cooling demand can be controlled within a certain range, and that each target refrigerator unit can be effectively cooled.

[0089] Step S520: Determine the compressor's operating frequency based on the total cooling demand and a preset frequency operation mapping table.

[0090] In one embodiment, the preset frequency operation mapping table is an operating frequency that can save power, set by experts based on experience. The frequency operation mapping table includes a preset demand range and a preset operating frequency, such as... Figure 3 As shown, the compressor's operating frequency is determined based on the total cooling demand and a preset frequency operation mapping table, including but not limited to the following steps:

[0091] Step S521: Determine the demand range in which the total cooling demand falls.

[0092] Step S522: Find the operating frequency corresponding to the demand range in the frequency operation mapping table, and use the operating frequency as the operating frequency of the compressor.

[0093] In one specific embodiment, the preset frequency operation mapping table is shown in the following table:

[0094]

[0095] In one embodiment, based on the total cooling demand obtained in step S510, the demand range in which the total cooling demand falls is first determined according to the demand range in the frequency operation mapping table. For example, if the obtained total cooling demand is 2550, referring to the frequency operation mapping table, this value is less than 3000 and greater than 2000. Therefore, the compressor operating frequency corresponding to the value less than 3000 is determined, and the compressor frequency is adjusted to 900. By obtaining the total cooling demand based on the cooling demand of each target refrigerator body, and searching for the corresponding compressor operating frequency in the preset frequency operation mapping table, energy savings can be achieved.

[0096] like Figure 5 As shown in the schematic diagram of the overall flow of the refrigeration control method provided in this application embodiment, the host first communicates with each refrigerator unit to obtain status parameters, including the refrigerator unit's volume, current temperature, and set temperature. The refrigeration demand of each refrigerator unit is calculated based on these parameters. If the refrigeration demand of any refrigerator unit is zero, it is determined that the refrigerator unit does not require refrigeration, and the compressor is turned off. If the refrigeration demand of at least one refrigerator unit is not zero, the refrigerator unit requiring refrigeration is selected as the target refrigerator unit. The compressor and electric switching valve are then turned on. The electric switching valve polls each refrigerator unit. When a target refrigerator unit is found, the electric switching valve connects to the output pipe corresponding to that target refrigerator unit. The total refrigeration demand is calculated based on the refrigeration demand of each target refrigerator unit. The optimal operating frequency is obtained through a frequency mapping table based on the total refrigeration demand. The polling time is short, and the total refrigeration demand is recalculated with each polling, thereby adjusting the compressor's optimal operating frequency and saving electricity.

[0097] Example 1: Taking the refrigeration system of a cabinet refrigerator as an example, and with reference to the accompanying drawings.

[0098] Cabinet-style refrigerator structure such as Figure 6As shown, the refrigerator compartment 11, rice compartment 12, freezer compartment 16, delicacy dry goods compartment 14, condiment compartment 15, and beverage compartment 13 are all distributed within the cabinet's storage space. The refrigerator is divided into a freezer compartment and a refrigerator compartment. The freezer compartment is located in the refrigerator compartment 11, and the refrigerator compartment is located in the freezer compartment 16. The refrigerator compartment and the freezer compartment are connected, and the freezer compartment is connected to the compressor. Through a series-parallel connection, the refrigerator's space utilization is greatly improved, and precise temperature control is achieved. There is at least one freezer compartment and at least one refrigerator compartment.

[0099] like Figure 7 As shown, Figure 7 This is a schematic diagram of a refrigeration system provided in an embodiment of this application. The refrigeration system includes a compressor 110, a condenser 120, an anti-condensation pipe 130, a dryer filter 140, an electric switching valve 150, and multiple refrigerator compartments. The multiple refrigerator compartments are distributed within the cabinet's storage space. Each refrigerator compartment is equipped with a sensor, including a temperature sensor and a diameter sensor. The temperature sensor is used to detect the temperature of the refrigerator compartment, and the diameter sensor is used to measure the volume of the refrigerator compartment. Each refrigerator compartment includes a freezer compartment 1, a refrigerator compartment 2, a refrigerator compartment 3, and a refrigerator compartment 4. Each of the freezer compartment 1, refrigerator compartment 2, refrigerator compartment 3, and refrigerator compartment 4 is connected to the compressor 110. The compressor 110 is connected to the electric switching valve 150 through the condenser 120, the anti-condensation pipe 130, and the dryer filter 140. The electric switching valve 150 is connected to multiple output pipes, with each output pipe corresponding to one refrigerator compartment. The refrigeration unit controls the compressor 110 and the electric switching valve 150 based on the information detected by the sensor, thereby controlling the temperature of each refrigerator unit to achieve centralized refrigeration and distributed cooling. The electric switching valve 150 polls each refrigerator unit to calculate the total cooling demand of each refrigerator unit and adjusts the compressor 110 to operate at the optimal frequency to reduce power consumption.

[0100] In one embodiment, the refrigeration system further includes components such as an evaporator, a capillary tube, a condenser fan, and a blower to achieve refrigeration. Components such as the compressor 110 and condenser 120 can also be located outdoors to reduce noise generated by the vibration of the compressor 110 during the refrigeration process.

[0101] Example 2: The following describes the specific process of the refrigeration control method using freezer 1, refrigerator 2, refrigerator 3 and refrigerator 4 as examples.

[0102] First, the refrigeration unit communicates with freezer 1, refrigerator 2, refrigerator 3, and refrigerator 4 respectively to obtain their status parameters, including the volume of each refrigerator compartment, current temperature, and set temperature (the preset shutdown temperature is the set temperature). Based on these parameters, the cooling demand of each refrigerator compartment is calculated. For example, the cooling demand of freezer 1 is 3500, the cooling demand of refrigerator 2 is 0, the cooling demand of refrigerator 3 is 0, and the cooling demand of refrigerator 4 is 1500. If the cooling demand of freezer 1 and refrigerator 4 is not zero, then freezer 1 and refrigerator 4 need to cool. If the cooling demand of refrigerator 2 and refrigerator 3 is zero, then refrigerator 2 and refrigerator 3 do not need to cool. In this case, two refrigerator compartments need to cool, so the compressor and electric switching valve are activated. The total cooling demand is the sum of the cooling demand of freezer 1 and refrigerator 4, calculated to be 5000. Based on the preset frequency mapping table, the compressor's operating frequency is adjusted to 2300. Then, each refrigerator unit is polled via an electric switching valve. According to the calculation, freezer 1 has the highest cooling demand, so polling begins with freezer 1. The electric switching valve connects to the output pipe corresponding to freezer 1, cooling it. When the current temperature of freezer 1 reaches the set temperature, the electric switching valve is redirected to the next refrigerator unit. Figure 7 As shown, the next refrigerator compartment is refrigerator compartment 2. At this time, the cooling demand of freezer compartment 1 is 0, the cooling demand of refrigerator compartment 2 is 0, the cooling demand of refrigerator compartment 3 is 0, and the cooling demand of refrigerator compartment 4 is 1500. The total cooling demand is recalculated and found to be 1500. The compressor's operating frequency is adjusted to 600 according to the preset frequency mapping table. Refrigerator compartment 2 has a cooling demand of 0 and does not need to cool. At this time, the total cooling demand remains unchanged, and the compressor's operating frequency is maintained. The electric switching valve is directed to the next refrigerator compartment, refrigerator compartment 3. In the new round of polling, the cooling demand of freezer compartment 1 and refrigerator compartment 2 is zero, the cooling demand of refrigerator compartment 3 is 2200, and the cooling demand of refrigerator compartment 4 is 1000. The total cooling demand is calculated to be 3200. According to the frequency operation mapping table, the compressor's operating frequency is adjusted to 1200 to cool refrigerator compartment 3. After cooling is completed, the electric switching valve is directed to the next refrigerator compartment, refrigerator compartment 4, and the calculation is repeated. The above operation not only enables accurate temperature control for each refrigerator compartment, but also ensures that the compressor operates at the optimal frequency after each polling, thereby reducing energy consumption and saving electricity. The query time for the cooling demand of each refrigerator compartment is short, completed within a few seconds. Through continuous communication and querying, the compressor can be adjusted to the optimal operating frequency.

[0103] like Figure 8 As shown, Figure 8 This is a schematic diagram of the system architecture platform of a cooling control method provided in one embodiment of this application.
