Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a refrigeration device. Background Technology

[0002] In current refrigerator refrigeration technology, the ice-making compartment typically uses either a freezer evaporator or a separate evaporator for air supply. Because the ice-making process has more stringent temperature requirements than other compartments, needing to maintain a low temperature for an extended period to complete ice making and storage, the refrigeration system frequently starts the compressor to meet ice-making demands. This significantly reduces the refrigeration system's operating time, leading to higher temperatures and larger temperature fluctuations in other compartments, affecting the overall temperature control performance and food preservation. Therefore, it is necessary to optimize the ice-making temperature control strategy to avoid excessive refrigeration time in the ice-making compartment and reduce frequent compressor starts and stops, achieving a balance between ice-making efficiency and the temperature stability of other compartments. Summary of the Invention

[0003] In view of this, the present application provides a refrigeration device. The refrigeration device disclosed in the present application improves the stability and energy efficiency of the refrigeration device by supplementing the cooling with ice making during the refrigeration operation, avoiding excessive occupation of the refrigeration time by the ice making room.

[0004] This application provides a refrigeration device, including: The box contains multiple storage compartments, including an ice-making compartment, a freezing compartment, and a refrigeration compartment. A refrigeration system for providing cooling capacity to the refrigeration equipment, comprising an ice-making circuit corresponding to the ice-making chamber, a freezing circuit corresponding to the freezing chamber, and a refrigeration circuit corresponding to the refrigeration chamber, wherein any one of the ice-making circuit, the freezing circuit, and the refrigeration circuit includes a compressor; A valve is used to control the flow of refrigerant to the ice-making circuit, the freezing circuit, or the refrigeration circuit; The sensor module includes multiple temperature sensors corresponding to the multiple storage compartments. Each temperature sensor is installed in a corresponding storage compartment and is used to collect the temperature of the corresponding storage compartment. The controller is connected to the refrigeration system, the sensor module, and the valve, respectively, and is configured to: Control the valve to switch to the refrigeration circuit so that the refrigeration equipment operates in refrigeration mode; If the first ice-making temperature of the ice-making room, as measured by the ice-making temperature sensor corresponding to the ice-making room, is greater than or equal to the first ice-making start-up temperature, the valve is controlled to switch from the refrigeration circuit to the ice-making circuit so that the refrigeration equipment operates in ice-making mode. When the ice-making chamber meets the first ice-making shutdown condition, the valve is controlled to switch from the ice-making circuit to the refrigeration circuit so that the refrigeration equipment operates in the refrigeration mode. The first ice-making shutdown condition is: the second ice-making temperature of the ice-making chamber, which is re-collected by the ice-making temperature sensor, is less than the first ice-making shutdown temperature, or the ice-making time of the ice-making chamber is greater than or equal to the first preset time.

[0005] In the above technical solution, the control valve switches to the refrigeration circuit, enabling the refrigeration equipment to operate in refrigeration mode. In this case, when the first ice-making temperature in the ice-making chamber is greater than or equal to the first ice-making start-up temperature, it indicates that the temperature in the ice-making chamber has risen to the point where refrigeration intervention is required. At this time, the control valve switches from the refrigeration circuit to the ice-making circuit, enabling the refrigeration equipment to operate in ice-making mode. This achieves proactive valve switching during refrigeration operation, providing short-term supplemental cooling to the ice-making circuit, preventing the ice from melting due to excessively high temperatures in the ice-making chamber, and delaying the moment when the ice-making chamber triggers independent ice-making startup due to temperature rise. This achieves a balance between ice-making efficiency and overall temperature control stability. Furthermore, when the ice-making chamber meets the first ice-making shutdown condition (i.e., the second ice-making temperature is less than the first ice-making shutdown temperature, or the ice-making duration is greater than or equal to the first preset duration), the control valve switches from the ice-making circuit back to the refrigeration circuit, allowing the refrigeration equipment to resume refrigeration mode operation, preventing excessive temperature rise in the refrigeration chamber due to prolonged occupation of the refrigeration circuit. This solution prevents the ice-making room from excessively occupying the refrigeration time by supplementing the cooling during refrigeration operation, reduces frequent compressor start-stop, and improves the operational stability and energy efficiency of the refrigeration equipment. It not only ensures the normal operation of the refrigeration mode, but also meets the ice-making and ice-storage needs of the ice-making room, achieving a balance between the overall temperature control performance and ice-making efficiency of the refrigeration equipment.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0022] It should be noted that the terms "first, second, third" used in the embodiments of this application are used to distinguish similar or different objects and do not represent a specific order of objects. It can be understood that "first, second, third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0023] In current refrigerator refrigeration technology, the ice-making compartment typically uses either a freezer evaporator or a separate evaporator for air supply. Because the ice-making process has more stringent temperature requirements than other compartments, needing to maintain a low temperature for an extended period to complete ice making and storage, the refrigeration system frequently starts the compressor to meet ice-making demands. This significantly reduces the refrigeration system's operating time, leading to higher temperatures and larger temperature fluctuations in other compartments, affecting the overall temperature control performance and food preservation. Therefore, it is necessary to optimize the ice-making temperature control strategy to avoid excessive refrigeration time in the ice-making compartment and reduce frequent compressor starts and stops, achieving a balance between ice-making efficiency and the temperature stability of other compartments.

[0024] In view of this, this application provides a refrigeration device, which includes a housing, a refrigeration system, valves, a sensor module, and a controller. The controller is configured to: control the valves to switch to the refrigeration circuit, so that the refrigeration device operates in refrigeration mode; when the first ice-making temperature of the ice-making chamber, collected by the ice-making temperature sensor corresponding to the ice-making chamber, is greater than or equal to the first ice-making start-up temperature, control the valves to switch from the refrigeration circuit to the ice-making circuit, so that the refrigeration device operates in ice-making mode; when the ice-making chamber meets the first ice-making shutdown condition, control the valves to switch from the ice-making circuit to the refrigeration circuit, so that the refrigeration device operates in refrigeration mode. The refrigeration device disclosed in this application improves the stability and energy efficiency of the refrigeration device by performing ice-making supplementary cooling during refrigeration operation, avoiding excessive occupation of the refrigeration time by the ice-making chamber.

[0025] To make the purpose and technical solution of this application clearer and more intuitive, the refrigeration equipment disclosed in this application will be described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a refrigeration device disclosed in an embodiment of this application. Figure 1 The refrigeration equipment shown includes: cabinet 1, refrigeration system 2 (see [link]). Figure 2 ), sensor module (not shown in the figure) and controller (not shown in the figure).

[0027] The housing 1 is the main structure of the refrigeration equipment, and multiple storage compartments are formed within it; these multiple storage compartments may include at least one refrigerator compartment, at least one freezer compartment, and at least one ice-making compartment. For example, as... Figure 1 At least one storage compartment shown includes a freezer compartment 11, a refrigerator compartment 15, and an ice-making compartment (which may be located in the cabinet 1, not shown in the figure). It should be understood that... Figure 1The example described uses a cabinet 1 with a refrigerator compartment, a freezer compartment, and an ice-making compartment. However, in actual applications, the number of refrigerator compartments, freezer compartments, and ice-making compartments inside the cabinet 1 of the refrigeration equipment can be one or more. This application does not limit the number of such compartments.

[0028] The refrigeration system is located inside the cabinet 1 and is used to provide cooling capacity for the refrigeration equipment. It forms an ice-making circuit corresponding to the ice-making chamber, a freezing circuit corresponding to the freezer chamber 11, and a refrigeration circuit corresponding to the refrigeration chamber 15. Each of the ice-making circuit, freezing circuit, and refrigeration circuit includes a compressor.

[0029] As an example, please see Figure 2 , Figure 2 This is a schematic diagram of a refrigeration system for a refrigeration device disclosed in an embodiment of this application. The refrigeration system may include a compressor 21, a condenser (not shown in the figure), a valve 23, multiple evaporators (such as an ice-making evaporator 221, a freezing evaporator, and a refrigeration evaporator 223), and passages for allowing refrigerant to flow through the various components. The valve 23 is used to control the flow of refrigerant to the ice-making circuit, the freezing circuit, or the refrigeration circuit; for example, the valve is a three-way valve.

[0030] Among them, the three refrigeration circuits of the freezer compartment 11, the refrigerator compartment 15 and the ice-making compartment 14 share core components such as compressor 21, condenser and valve 23, and realize the dynamic distribution of refrigerant flow through valve switching passage.

[0031] As an example, such as Figure 2 The refrigerant flow direction of each operating loop in the refrigeration system shown is as follows: Ice-making circuit: The compressor compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which is then sent to the condenser to dissipate heat and transform into a high-pressure liquid refrigerant. The high-pressure liquid refrigerant flows through valves and enters the ice-making evaporator, where it absorbs heat and evaporates into a low-temperature, low-pressure gaseous refrigerant, providing cooling for the ice-making compartment. Finally, the low-temperature, low-pressure gaseous refrigerant returns to the compressor to begin the next cycle.

[0032] Refrigeration Circuit: The compressor compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which is then delivered to the condenser. There, it dissipates heat to the outside and transforms into a high-pressure liquid refrigerant. This high-pressure liquid refrigerant flows through a valve and enters the evaporator. In the evaporator, the refrigerant absorbs heat from the freezer compartment, vaporizes, and becomes a low-temperature, low-pressure gaseous refrigerant. This process cools the freezer compartment; for example, in a refrigerator, the evaporator absorbs heat from the freezer compartment to maintain its low temperature. Finally, the low-temperature, low-pressure gaseous refrigerant returns to the compressor to begin the next cycle.

[0033] Refrigeration Circuit: The compressor compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which is then delivered to the condenser, where it dissipates heat to the outside and transforms into a high-pressure liquid refrigerant. The high-pressure liquid refrigerant flows through a valve and enters the refrigeration evaporator, where it absorbs heat and evaporates into a low-temperature, low-pressure gaseous refrigerant. It then flows through the refrigeration evaporator, continuing to absorb heat and providing cooling to the freezer compartment. The low-temperature, low-pressure gaseous refrigerant, having completed the entire heat absorption process, finally returns to the compressor, is compressed again, and begins the next refrigeration cycle. This path enables a single-loop refrigerant to simultaneously cool both the refrigeration and freezer compartments.

[0034] The sensor module includes multiple temperature sensors corresponding to multiple storage compartments. Each temperature sensor is located in its corresponding storage compartment and is used to collect the temperature of that compartment. As an example, when... Figure 1 When the multiple storage compartments of the refrigeration equipment shown include an ice-making compartment, a freezer compartment 11, and a refrigerator compartment 15, the sensor module may include an ice-making temperature sensor, a freezer temperature sensor, and a refrigerator temperature sensor.

[0035] The controller is used to control the operating parameters of valves, compressors and other devices in refrigeration equipment, etc., which will not be exemplified one by one in the embodiments of this application.

[0036] It should be noted that refrigeration equipment may also include other components ( Figure 1 (Not shown in the image), such as ambient humidity sensors, evaporator temperature sensors, memory, etc., which will not be listed here in this application.

[0037] The above combination Figure 1 and Figure 2 The structure of the refrigeration equipment is briefly described, in which the ice-making chamber uses a separate evaporator for air supply. Because the ice-making process requires maintaining a low temperature for an extended period to complete ice making and storage, the refrigeration system frequently starts the compressor to meet ice-making demands, significantly reducing the system's operating time. Therefore, this application further improves the evaporator structure of the ice-making chamber by assisting the ice-making chamber in cooling during freezing mode, thereby reducing the operating time of the ice-making chamber.

[0038] Please see Figures 1-4 , Figure 3 This is a schematic diagram of the structure of an evaporator assembly of a refrigeration device disclosed in an embodiment of this application. Figure 4 This is a schematic diagram of the structure of an evaporator assembly of another refrigeration device disclosed in an embodiment of this application. Figure 1 and Figure 2 As shown, the refrigeration equipment includes: a housing 1, a door (not shown in the figure), and a refrigeration system 2.

[0039] The cabinet 1 has a freezer compartment 11, a refrigerator compartment 15, a freezer evaporator compartment 12 and an ice-making evaporator compartment 13. The freezer evaporator compartment 12 is connected to the freezer compartment 11 and separated from the ice-making evaporator compartment 13. The door, connected to the cabinet 1, is used to open or close the freezer compartment 11; Ice-making room 14 is located in the box body 1 or the door body and is connected to the ice-making evaporator chamber 13; Refrigeration system 2, installed in cabinet 1, includes: Compressor 21 is installed inside housing 1; Evaporator assembly 22, connected to compressor 21, includes: An ice-making evaporator 221 is installed in the ice-making evaporator compartment 13. The ice-making evaporator 221 is connected in series with the compressor 21 to form an ice-making circuit. The ice-making evaporator 221 is used to cool the ice-making chamber 14. A refrigerated evaporator 223 is installed in the refrigerated compartment 15. The refrigerated evaporator 223 is connected in series with the compressor 21 to form a refrigerated circuit. A frozen evaporator 222 is connected in series with the refrigerated circuit. The refrigerated evaporator 223 is used to cool the refrigerated compartment 15. Refrigeration evaporator 222, connected in series with compressor 21 to form a refrigeration circuit, includes: The refrigeration unit 2221 is located in the refrigeration evaporator compartment 12 and is used to refrigerate the refrigeration compartment 11. The ice-making and refrigeration unit 2222 is connected in series with the freezing and refrigeration unit 2221 and is disposed in the ice-making evaporator chamber 13; the ice-making and refrigeration unit 2222 is used to refrigerate the ice-making chamber 14. Valve 23 is connected to the ice-making circuit, the freezing circuit, or the refrigeration circuit. Valve 23 is used to control the flow of refrigerant from compressor 21 to the ice-making circuit, the freezing circuit, or the refrigeration circuit. Air supply assembly 24 is installed inside housing 1. The air supply assembly includes: A refrigeration fan is used to deliver the cooling capacity provided by the refrigeration evaporator 222 into the refrigeration compartment 11; An ice-making fan is used to send cold air from the ice-making evaporator chamber 13 into the ice-making room 14. A refrigeration fan is used to supply air to the refrigeration compartment 15.

[0040] like Figure 1 , Figure 2 , Figure 3As shown, the refrigeration equipment provided in this embodiment divides the refrigeration evaporator 222 into a refrigeration unit 2221 and an ice-making unit 2222 connected in series. Therefore, when the refrigeration chamber 11 meets the refrigeration operation conditions (for example, the refrigeration operation conditions are that the temperature of the refrigeration chamber is greater than or equal to the first refrigeration start-up temperature and there is no priority ice-making demand, or the refrigeration operation conditions are that the ice-making chamber requires the ice-making chamber to meet the fourth ice-making shutdown condition after startup and the third refrigeration temperature is greater than or equal to the first refrigeration shutdown temperature), it is necessary to... When the refrigeration system is activated, valve 23 connects the refrigeration circuit. At this time, the refrigeration unit 2221 and the ice-making refrigeration unit 2222 operate simultaneously. The refrigeration unit 2221 lowers the temperature of the refrigeration evaporator chamber 12, and the ice-making refrigeration unit 2222 lowers the temperature of the ice-making evaporator chamber 13. The air supply assembly 24 delivers cold air from the refrigeration evaporator chamber 12 into the refrigeration chamber 11 to lower its temperature, and delivers cold air from the ice-making evaporator chamber 13 into the ice-making chamber 14 to lower its temperature. Thus, auxiliary cooling of the ice-making chamber 14 can be achieved when the refrigeration system is activated.

[0041] When the freezer compartment 11 meets the conditions for stopping the freezer operation (for example, the freezer compartment temperature is lower than the first freezer shutdown temperature, or the freezer duration is greater than or equal to the preset duration), valve 23 disconnects the freezer circuit. Furthermore, when the refrigerator compartment meets the conditions for refrigeration operation (e.g., the second refrigeration temperature is greater than or equal to the first refrigeration shutdown temperature), the refrigerator circuit is connected; or, when the ice-making compartment meets the conditions for ice-making operation (e.g., the eleventh ice-making temperature is greater than or equal to the first ice-making shutdown temperature), the ice-making circuit is connected. If the compartment has already been operating in freezer mode before switching to the ice-making circuit, since the freezer evaporator compartment 12 and the ice-making compartment 14 have already been cooled to a certain extent by the freezer cooling unit 2221, the cooling time required for ice-making can be shortened after the ice-making mode is activated, thereby reducing the operating time occupied by the ice-making mode. In summary, compared to designs that use only one evaporator 222 to supply air to the ice-making chamber, the refrigeration equipment provided in this application does not simultaneously cool the freezer compartment when the ice-making mode is activated, thus preventing the freezer compartment 11 from becoming too cold. Furthermore, compared to designs that use a separate evaporator 221 to supply air to the ice-making chamber, this application's solution can shorten the operating time for ice making, thereby extending the operating time for refrigeration and preventing the freezer compartment 11 from becoming too hot.

[0042] like Figure 2As shown, the refrigeration system 2 also includes a capillary tube 25, which can throttle and reduce pressure and regulate flow. In addition, the refrigeration system 2 may also include a dryer filter 26, which is connected upstream of the capillary tube 25. The dryer filter 26 can filter impurities in the refrigerant and absorb moisture in the refrigerant, preventing these impurities from clogging the extremely fine capillary tube 25 or damaging the compressor 21.

[0043] like Figure 1 , Figure 2 As shown, the refrigeration equipment provided in this embodiment can also form a cold storage compartment 15 inside the housing 1. In order to refrigerate the cold storage compartment 15, the evaporator assembly 22 also includes a cold storage evaporator 223. The cold storage evaporator 223 is connected in series with the compressor 21 to form a cold storage circuit, and the freezing evaporator 222 is connected in series with the cold storage circuit. Thus, the refrigerant passing through the cold storage evaporator 223 will also flow through the freezing evaporator 222. The cooling capacity of the refrigerant during refrigeration can be used to supplement the cooling of the freezing compartment, reduce the temperature rise of the freezing compartment, and improve the cooling effect of the freezing compartment. Furthermore, since the ice-making refrigeration section 2222 of the freezing evaporator 222 is located in the ice-making evaporator compartment 13, it can also provide auxiliary cooling to the ice-making compartment 14 when the refrigeration is turned on.

[0044] In some embodiments, the air supply assembly 24 may include a refrigeration fan 241, an ice-making fan 242, and a refrigerator fan.

[0045] like Figure 1 , Figure 2 As shown, the refrigerant passing through the refrigeration evaporator 223 flows through the freezing evaporator 222. Since the ice-making cooling section 2222 of the freezing evaporator 222 is located inside the ice-making evaporator compartment 13, in refrigeration mode, it can simultaneously provide auxiliary cooling to both the freezing compartment 11 and the ice-making compartment 14. Therefore, when valve 23 is switched to the refrigeration circuit, the ice-making fan 242, the freezing fan 241, and the refrigeration fan can be turned on.

[0046] like Figure 1 , Figure 2 As shown, since the ice-making and refrigeration section 2222 of the refrigeration evaporator 222 is located inside the ice-making evaporator compartment 13, it can also provide auxiliary cooling to the ice-making chamber 14 during operation in refrigeration mode. Therefore, when valve 23 is switched to the refrigeration circuit, the ice-making fan 242 and the refrigeration fan 241 can be turned on.

[0047] It should be noted that the ice-making room 14 can be located inside the refrigerator room 15 or the freezer room 11, or it can be located on the door of the refrigeration equipment; there is no limitation on this.

[0048] The locations of the freezer evaporator compartment 12 and the ice-making evaporator compartment 13 can be varied. For example, the freezer evaporator compartment 12 can be located in the freezer compartment 11, and the ice-making evaporator compartment 13 can be located in the ice-making compartment 14. Alternatively, both the freezer evaporator compartment 12 and the ice-making evaporator compartment 13 can be located within the freezer compartment 11, such as... Figure 3 , Figure 4 As shown, the freezer evaporator compartment 12 and the ice-making evaporator compartment 13 can be separated by a heat insulation component 16, ensuring that the temperatures of the freezer evaporator compartment 12 and the ice-making evaporator compartment 13 do not affect each other. Additionally, an insulation layer can be provided on the inner or outer wall of the ice-making evaporator compartment 13 to isolate it from the freezer compartment 11, preventing the temperature inside the ice-making evaporator compartment 13 from affecting the temperature of the freezer compartment 11. The aforementioned heat insulation component 16 and insulation layer can be made of materials such as foam or insulation cotton.

[0049] like Figure 3 As shown, the air supply assembly 24 may include: a refrigeration air supply duct (not shown), an ice-making air supply duct (not shown), a refrigeration fan 241, and an ice-making fan 242. The refrigeration air supply duct is connected between the refrigeration evaporator chamber 12 and the refrigeration chamber 11. The refrigeration fan 241 is installed in the refrigeration air supply duct to deliver cold air from the refrigeration evaporator chamber 12 into the refrigeration chamber 11. The ice-making air supply duct is connected between the ice-making evaporator chamber 13 and the ice-making chamber 14. The ice-making fan 242 is installed in the ice-making air supply duct to deliver cold air from the ice-making evaporator chamber 13 into the ice-making chamber 14. Thus, cold air can be supplied to the refrigeration chamber 11 and the ice-making chamber 14.

[0050] Specifically, both the refrigeration fan 241 and the ice-making fan 242 can be centrifugal fans, which can be installed on the rear wall of the inner liner of the freezer compartment 11. The axial air inlet of the refrigeration fan 241 is connected to the freezer evaporator compartment 12, and the radial air outlet of the refrigeration fan 241 is connected to multiple refrigeration air supply ducts. These multiple refrigeration air supply ducts guide the cold air in the freezer evaporator compartment 12 to different locations within the freezer compartment 11, thereby making the cooling of the freezer compartment 11 more uniform. The axial air inlet of the ice-making fan 242 is connected to the ice-making evaporator compartment 13, and the radial air outlet of the ice-making fan 242 can be connected to the ice-making air supply duct or directly to the ice-making compartment 14.

[0051] It should be noted that, Figures 1-4 The components of the refrigeration equipment illustrated herein do not constitute a specific limitation on the refrigeration equipment. The components of the refrigeration equipment may include more or fewer components than illustrated, or some components may be combined, some components may be separated, or different component arrangements may be made. The illustrated components may be implemented in hardware, software, or a combination of software and hardware. That is to say, the refrigeration equipment disclosed in the embodiments of this application may also include… Figures 1-4Other components not shown.

[0052] Through the above description of the system architecture and other hardware of the refrigeration equipment, the functions of each component of the refrigeration equipment can be understood. The following will further describe the controller provided in the embodiments of this application for controlling valve switching.

[0053] Please see Figure 5 , Figure 5 This is a schematic flowchart illustrating a control method for a controller of a refrigeration device disclosed in an embodiment of this application. Figure 5 The control method shown includes the following steps: Step 501: The controller switches the valve to the refrigeration circuit so that the refrigeration equipment operates in refrigeration mode.

[0054] Optionally, when there is a need for refrigeration in the refrigeration room (for example, when the refrigeration room requires to be turned on but does not meet the priority ice-making conditions, or when the priority ice-making ends and the refrigeration is switched to refrigeration after the refrigeration room requires to be turned on), the control valve can be switched to the refrigeration circuit.

[0055] It should be understood that after the control valve is switched to the refrigeration circuit, such as Figure 2 As shown, the refrigerant flow loop is: compressor-valve-refrigeration evaporator-freezing evaporator, which provides cooling capacity to the refrigerator and freezer compartments.

[0056] In some embodiments, the refrigeration evaporator is connected in series with the refrigeration circuit, and when the valve is switched to the refrigeration circuit, the controller controls the refrigeration fan, ice-making fan and refrigeration fan to turn on.

[0057] It should be understood that, such as Figure 1 , Figure 2 As shown, the refrigeration evaporator is connected in series with the refrigeration circuit. The refrigerant passing through the refrigeration evaporator flows through the freezing evaporator. Furthermore, since the ice-making refrigeration section of the freezing evaporator is located inside the ice-making evaporator compartment, it can simultaneously provide auxiliary cooling to both the freezer compartment and the ice-making compartment in refrigeration mode. Therefore, when the valve is switched to the refrigeration circuit, the ice-making fan, the freezing fan, and the refrigeration fan can be turned on.

[0058] Furthermore, in any step of this solution involving "switching the valve to the refrigeration circuit", the refrigeration fan, ice-making fan, and freezing fan can be turned on, and this application will not provide examples of each one.

[0059] As can be seen, by implementing the above embodiments, since the refrigerant passing through the refrigeration evaporator flows through the freezing evaporator, and the ice-making refrigeration section of the freezing evaporator is located inside the ice-making evaporator compartment, auxiliary cooling of the freezing compartment and the ice-making compartment can be provided simultaneously in refrigeration mode. In this solution, when the valve switches to the refrigeration circuit, the refrigeration fan, ice-making fan, and freezing fan are all turned on. The cooling capacity generated by the refrigeration evaporator and the freezing evaporator (including their ice-making refrigeration sections) is delivered to the refrigeration compartment, ice-making compartment, and freezing compartment respectively through the three fans. This achieves effective cooling of all three compartments simultaneously in a single refrigeration mode, thereby reducing the frequency of individually starting the freezing mode or ice-making mode, lowering the number of compressor start-stop cycles, and reducing overall energy consumption.

[0060] Step 502: When the first ice-making temperature of the ice-making room, collected by the ice-making temperature sensor corresponding to the ice-making room, is greater than or equal to the first ice-making start-up temperature, the controller controls the valve to switch from the refrigeration circuit to the ice-making circuit so that the refrigeration equipment operates in ice-making mode.

[0061] In this embodiment, the first ice-making start-up temperature is a preset threshold. For example, the first ice-making start-up temperature is the start-up temperature of the ice-making chamber (e.g., -12°C).

[0062] It should be noted that when the refrigeration equipment is running in refrigeration mode, if the first ice-making temperature in the ice-making compartment is greater than or equal to the first ice-making start-up temperature, it indicates that the temperature in the ice-making compartment has risen to the point where refrigeration intervention is required. At this time, the valve can be switched from the refrigeration circuit to the ice-making circuit. This allows for proactive valve switching during refrigeration operation, enabling a short-term ice-making supplementary cooling mode. This prevents the ice in the ice-making compartment from becoming too hot and melting the ice, thus avoiding prolonged high-load ice-making by the compressor. It also delays the moment when the ice-making compartment triggers independent ice-making operation due to temperature rise, avoiding frequent compressor starts and achieving a balance between ice-making efficiency and overall temperature control stability.

[0063] It should be understood that after the control valve is switched to the ice-making circuit, the refrigerant flow path is: compressor-valve-ice-evaporator, thus providing cooling capacity to the ice-making room.

[0064] Step 503: When the ice-making room meets the first ice-making shutdown condition, the controller controls the valve to switch from the ice-making circuit to the refrigeration circuit so that the refrigeration equipment operates in refrigeration mode.

[0065] In this embodiment, the first ice-making shutdown condition is: the second ice-making temperature of the ice-making chamber, re-collected by the ice-making temperature sensor, is less than the first ice-making shutdown temperature; or, the ice-making time of the ice-making chamber is greater than or equal to a first preset time. The first ice-making shutdown temperature is a preset threshold. For example, the first ice-making shutdown temperature is the shutdown temperature of the ice-making chamber (e.g., -15°C). The first preset time is a preset duration, such as 15 minutes.

[0066] It should be understood that ice-making time can be interpreted as the continuous running time accumulated from the moment the ice-making mode is entered (i.e., the moment the valve switches to the ice-making circuit). To prevent the ice-making temperature from failing to reach the target for an extended period due to sensor malfunction or insufficient refrigerant, thus excessively occupying the refrigeration system's running time, the ice-making shutdown condition in this solution includes the ice-making time of the ice-making chamber being greater than or equal to the preset time.

[0067] It should be noted that in step 502, to address the temperature rise in the ice-making compartment, the valve is switched to the ice-making circuit, initiating a short-term ice-making supplementary cooling mode. Supplementary cooling is not a case of the longer the better: if supplementary cooling is stopped too early, the ice-making compartment temperature may not have effectively decreased, and supplementary cooling will be triggered again quickly, leading to frequent valve switching and multiple compressor frequency increases, increasing energy consumption; if it is stopped too late, prolonged occupation of the refrigeration circuit may cause the refrigerator compartment temperature to rise beyond the allowable range. Therefore, it is necessary to set the first ice-making shutdown condition appropriately to switch back to refrigerator mode at the right time.

[0068] As can be seen, by implementing the above embodiments, the control valve switches to the refrigeration circuit, enabling the refrigeration equipment to operate in refrigeration mode. In this case, when the first ice-making temperature of the ice-making chamber is greater than or equal to the first ice-making start-up temperature, it indicates that the temperature of the ice-making chamber has risen to the temperature requiring refrigeration intervention. At this time, the control valve switches from the refrigeration circuit to the ice-making circuit, enabling the refrigeration equipment to operate in ice-making mode. This achieves proactive valve switching during refrigeration operation, providing short-term supplemental cooling to the ice-making circuit, preventing the ice from melting due to excessively high temperatures in the ice-making chamber, and delaying the moment when the ice-making chamber triggers independent ice-making startup due to temperature rise. This achieves a balance between ice-making efficiency and overall temperature control stability. Furthermore, when the ice-making chamber meets the first ice-making shutdown condition (i.e., the second ice-making temperature is less than the first ice-making shutdown temperature, or the ice-making time is greater than or equal to the first preset time), the control valve switches from the ice-making circuit back to the refrigeration circuit, enabling the refrigeration equipment to resume refrigeration mode operation, avoiding excessive temperature rise in the refrigeration chamber due to prolonged occupation of the refrigeration circuit. This solution prevents the ice-making room from excessively occupying the refrigeration time by supplementing the cooling during refrigeration operation, reduces frequent compressor start-stop, and improves the operational stability and energy efficiency of the refrigeration equipment. It not only ensures the normal operation of the refrigeration mode, but also meets the ice-making and ice-storage needs of the ice-making room, achieving a balance between the overall temperature control performance and ice-making efficiency of the refrigeration equipment.

[0069] In the above scheme, the controller switches to the ice-making circuit for short-term supplemental cooling during refrigeration mode operation based on a comparison between the ice-making chamber temperature and the initial ice-making start-up temperature. However, during a single continuous compressor operation (i.e., a complete cycle from compressor start-up to shutdown), if the ice-making chamber temperature repeatedly rises above the start-up threshold due to poor insulation, high ambient temperature, or frequent door opening, the valves will frequently switch back and forth between the refrigeration and ice-making circuits, creating a dead loop. Furthermore, repeated valve switching and multiple compressor frequency increases lead to increased energy consumption and accelerated valve wear, shortening their lifespan. Therefore, the following further limits the number of supplemental cooling cycles before switching to the ice-making circuit.

[0070] Please see Figure 6 , Figure 6 This is a schematic flowchart illustrating another control method for a controller of a refrigeration device disclosed in an embodiment of this application. Figure 6 The control method shown includes the following steps: Step 601: The controller switches the valve to the refrigeration circuit so that the refrigeration equipment operates in refrigeration mode.

[0071] For the specific implementation of step 601, please refer to the content of step 501 above, which will not be repeated here.

[0072] Step 6021: When the number of recooling cycles in the ice-making chamber is less than a threshold value, and the first ice-making temperature is greater than or equal to the first ice-making start-up temperature, the controller switches the valve from the refrigeration circuit to the ice-making circuit. The number of recooling cycles is the number of times the valve switches from the refrigeration circuit to the ice-making circuit while the compressor is running continuously in refrigeration mode; the threshold value is a preset non-negative integer (e.g., 3 times).

[0073] For example, the initial ice-making start-up temperature is -12℃, and the threshold for the first replenishment is 3 times. After the compressor starts, the refrigeration equipment initially operates in refrigeration mode. The controller maintains a counter N for the number of replenishment cycles, initially set to 0. After running in refrigeration mode for a period of time, the current replenishment cycle N = 0, which is less than 3 times. At this point, the ice-making room temperature rises to -9℃, which is higher than the initial ice-making start-up temperature of -12℃. The controller then switches the valve from the refrigeration circuit to the ice-making circuit, performing the first replenishment cycle and updating the replenishment cycle N to 1.

[0074] As can be seen, by implementing the above embodiments, by comparing the number of times of replenishment cooling and the number of times threshold, when the number of times of replenishment cooling in the ice-making chamber is less than the number of times threshold, the comparison between the first ice-making temperature and the first ice-making start-up temperature is then performed. This effectively limits the number of times the ice-making chamber occupies the refrigeration system during the continuous operation of the compressor in refrigeration mode. It avoids frequent valve switching caused by repeated temperature rises in the ice-making chamber, thereby reducing mechanical wear and switching energy consumption of the valves, extending valve life, and ensuring the continuity of refrigeration mode operation and the temperature control stability of other chambers.

[0075] Step 6022: If the number of recooling cycles is greater than or equal to the threshold number, the controller controls the valve to remain connected to the refrigeration circuit so that the refrigeration equipment continues to operate in refrigeration mode.

[0076] It should be understood that after the number of replenishment cycles exceeds the threshold, even if the temperature of the ice-making room is greater than or equal to the first ice-making start-up temperature, the system will no longer switch from the refrigeration circuit to the ice-making circuit until the compressor starts up again and the replenishment cycle is reset.

[0077] As can be seen, after implementing the above embodiments, if the number of recooling cycles exceeds the threshold, it indicates that the valve switching is too frequent. The valve will no longer switch to the ice-making circuit and will continue to keep the refrigeration circuit connected. This avoids the valve from frequently operating within a single compressor cycle, effectively extending the valve's service life and reducing switching energy consumption, while ensuring the temperature stability of the refrigeration compartment.

[0078] Step 6023: If the number of recooling cycles in the ice-making room is less than the threshold number and the first ice-making temperature is less than the first ice-making start-up temperature, the controller controls the valve to remain connected to the refrigeration circuit so that the refrigeration equipment continues to operate in refrigeration mode.

[0079] Step 603: When the ice-making room meets the first ice-making shutdown condition, the controller controls the valve to switch from the ice-making circuit to the refrigeration circuit so that the refrigeration equipment operates in refrigeration mode.

[0080] For the specific implementation of step 603, please refer to the content of step 503 above, which will not be repeated here.

[0081] In the actual operation of refrigeration equipment, there are three types of start-up requests: refrigeration compartments, freezer compartments, and ice-making compartments. Each of these requests corresponds to a specific start-up temperature trigger condition. Temperature thresholds are used to determine whether the corresponding circuit needs to be switched to meet the cooling needs of the respective compartment.

[0082] The following sections describe these three scenarios of requesting to start up. In particular, when multiple compartments request to start up simultaneously, they are usually processed according to time sequence or fixed priority (such as ice making first, freezing second, and refrigeration last).

[0083] 1. The cold storage room must be kept running.

[0084] It should be noted that the temperature in the refrigerator compartment can fluctuate within a certain range (e.g., 3℃~6℃), and a short delay in refrigeration has little impact on food preservation. However, the ice-making compartment is extremely sensitive to temperature fluctuations: if its temperature rises too high, it may cause partial melting and clumping of the ice, affecting the quality of the ice. Based on this characteristic, this solution can prioritize responding to the ice-making request and control the refrigeration equipment to operate in ice-making mode when the refrigerator compartment requests to be turned on and the ice-making compartment temperature has risen to a relatively low but intervention-required threshold (e.g., the second ice-making start-up temperature) (the priority ice-making method when the refrigerator compartment requests to be turned on).

[0085] Furthermore, in refrigeration equipment with three functional compartments—freezing, refrigeration, and ice making—a control logic that prioritizes ice making followed by refrigeration when the refrigeration compartment requires operation fully utilizes the compressor's single-cycle startup time, thereby improving the refrigeration system's efficiency. Please see [link / reference]. Figure 7 , Figure 7 This is a schematic flowchart illustrating another control method for a controller of a refrigeration device disclosed in an embodiment of this application. Figure 7 The control method shown includes the following steps: Step 7011: When the first refrigeration temperature in the refrigeration compartment is greater than or equal to the first refrigeration start-up temperature, and the third ice-making temperature in the ice-making compartment is greater than or equal to the second ice-making start-up temperature, the controller controls the valve to switch to the ice-making circuit so that the refrigeration equipment operates in ice-making mode.

[0086] In this embodiment, the second ice-making start-up temperature is lower than the first ice-making start-up temperature, and the third ice-making temperature is acquired by an ice-making temperature sensor. Optionally, the second ice-making start-up temperature is a preset threshold. For example, the first ice-making start-up temperature is the start-up temperature of the ice-making chamber (e.g., -12°C), and the second ice-making start-up temperature is equal to the start-up temperature of the ice-making chamber minus 1 (e.g., -13°C).

[0087] It should be noted that if the third ice-making temperature of the ice-making compartment is greater than or equal to the first ice-making start-up temperature, it indicates that the ice-making compartment requires activation. Therefore, in this solution, the second ice-making start-up temperature is lower than the first ice-making start-up temperature. When the ice-making compartment temperature rises to the second ice-making start-up temperature, it indicates that the ice-making compartment temperature has recovered somewhat, but has not yet reached the required start-up temperature. If the refrigerator compartment requires activation, the refrigeration system can prioritize cooling the ice-making compartment in advance to lower its temperature, preventing the ice-making compartment from requiring activation alone in a short period of time, thus avoiding frequent compressor starts.

[0088] In this embodiment of the application, the first refrigeration temperature is collected by a refrigeration temperature sensor corresponding to the refrigeration compartment.

[0089] Optionally, the first refrigerator start-up temperature is a preset threshold. For example, the first refrigerator start-up temperature is the start-up temperature of the refrigerator compartment (e.g., 6°C).

[0090] It should be noted that if the first refrigeration temperature in the refrigerator compartment is greater than or equal to the first refrigeration start-up temperature, it indicates that the refrigerator compartment meets the start-up conditions, and the compressor can be controlled to run, with the valves switched to the refrigeration circuit. However, further, if the first refrigeration temperature in the refrigerator compartment is greater than or equal to the first refrigeration start-up temperature, and the third ice-making temperature in the ice-making compartment is greater than or equal to the second ice-making start-up temperature, it indicates that although the refrigerator compartment meets the start-up conditions, there is a demand for ice making. Therefore, ice making should be prioritized, and the valves should be switched to the ice-making circuit so that the refrigeration equipment operates in ice-making mode.

[0091] Step 7012: When the first refrigeration temperature in the refrigeration compartment is greater than or equal to the first refrigeration start-up temperature, and the third ice-making temperature in the ice-making compartment is less than the second ice-making start-up temperature, the controller controls the valve to switch to the refrigeration circuit.

[0092] It should be noted that if the first refrigeration temperature in the refrigeration compartment is greater than or equal to the first refrigeration start-up temperature, and the third ice-making temperature in the ice-making compartment is less than the second ice-making start-up temperature, it means that the refrigeration compartment meets the start-up conditions and there is no need for ice making at this time. The valve can be directly controlled to switch to the refrigeration circuit so that the refrigeration equipment can operate in refrigeration mode.

[0093] Step 7021: When the ice-making room meets the second ice-making shutdown condition, the controller controls the valve to switch from the ice-making circuit to the refrigeration circuit.

[0094] In this embodiment of the application, the second ice-making shutdown condition is: the fourth ice-making temperature of the ice-making chamber, which is re-collected by the ice-making temperature sensor, is less than the second ice-making shutdown temperature, or the ice-making time of the ice-making chamber is greater than or equal to the second preset time.

[0095] Optionally, the second ice-making shutdown temperature is lower than the first ice-making shutdown temperature, and the second ice-making shutdown temperature is a preset threshold. For example, the first ice-making shutdown temperature is the shutdown temperature of the ice-making chamber (e.g., -15℃), and the second ice-making shutdown temperature is equal to the shutdown temperature of the ice-making chamber minus a preset value. For example, the second ice-making shutdown temperature is equal to the shutdown temperature of the ice-making chamber minus 1, which is -16℃.

[0096] Optionally, the second preset duration can be longer than the first preset duration. For example, the first preset duration is 15 minutes, and the second preset duration is 30 minutes.

[0097] It should be understood that in the above steps, the temperature of the ice-making chamber that triggers priority ice making is close to the start-up temperature of the ice-making chamber. To achieve a sufficient low-temperature maintenance time, the temperature of the ice-making chamber needs to be lowered to a relatively low level to avoid repeated short-term supplemental cooling under refrigeration mode operation. Therefore, this solution sets different secondary ice-making shutdown conditions to make full use of the compressor's operating window and lower the temperature of the ice-making chamber to a low level.

[0098] Step 7022: If the ice-making room does not meet the second ice-making shutdown condition, the controller controls the valve to remain connected to the ice-making circuit so that the refrigeration equipment continues to operate in ice-making mode.

[0099] It should be noted that if the ice-making room does not meet the second ice-making shutdown conditions, it will continue to operate in ice-making mode until the ice-making room meets the second ice-making shutdown conditions, at which point the control valve will switch from the ice-making circuit to the refrigeration circuit.

[0100] As can be seen, by implementing the above embodiments, when the first refrigeration temperature in the refrigeration compartment is greater than or equal to the first refrigeration start-up temperature and the third ice-making temperature in the ice-making compartment is greater than or equal to the second ice-making start-up temperature, it indicates that although the refrigeration compartment meets the start-up conditions, there is a demand for ice making. Ice making can be prioritized, and the control valve switches to the ice-making circuit to operate in ice-making mode. This avoids the ice-making temperature from further increasing, which would cause the compressor to frequently start due to a need to start up again in a short period of time. Furthermore, when the ice-making compartment meets the second ice-making shutdown condition, the control valve switches the control valve back from the ice-making circuit to the refrigeration circuit. This condition includes a fourth ice-making temperature lower than the second ice-making shutdown temperature or an ice-making duration greater than or equal to a second preset duration.

[0101] Specifically, the second ice-making shutdown temperature is lower than the first ice-making shutdown temperature, and the second preset duration is longer than the first preset duration. This means that a lower temperature threshold and a longer allowable operating time are used during priority ice making, thereby lowering the ice-making compartment to a relatively low level and achieving a more sustained low-temperature maintenance effect. This solution can significantly extend the insulation time of the ice-making compartment through a single priority ice making operation, reducing the number of subsequent recooling cycles. Simultaneously, it fully utilizes the compressor's operating window without additional startups, improving ice-making efficiency and overall energy efficiency while ensuring temperature control in the refrigerator compartment.

[0102] 2. The freezer compartment must be kept running.

[0103] It should be noted that both the freezer compartment and the ice-making compartment are extremely sensitive to temperature fluctuations. However, frozen food in the freezer compartment will not experience rapid deterioration in quality if it experiences small temperature fluctuations (e.g., a 2°C rise) within a short period, as long as the temperature does not remain above the freezing point for an extended period. However, if the temperature in the ice-making compartment rises too high, the surface of the ice will partially melt, making it prone to sticking and clumping together upon refreezing, severely impacting ice-making quality and user experience. Based on this characteristic, this solution prioritizes ice-making requests when the freezer compartment requests to start and the ice-making compartment temperature has risen to a relatively low but intervention-required threshold (e.g., the second ice-making start-up temperature), controlling the refrigeration equipment to operate in ice-making mode (the priority ice-making method when the freezer compartment requests to start).

[0104] Furthermore, in refrigeration equipment with three functional compartments—freezing, refrigeration, and ice making—a control logic that prioritizes ice making, followed by freezing, and finally refrigeration, when the freezing compartment requires operation, fully utilizes the compressor's single-cycle startup time, thereby improving the refrigeration system's efficiency. Please see [link / reference]. Figure 8 , Figure 8 This is a schematic flowchart illustrating another control method for a controller of a refrigeration device disclosed in an embodiment of this application. Figure 8 The control method shown includes the following steps: Step 8011: When the first freezing temperature in the freezing chamber is greater than or equal to the first freezing start-up temperature, and the fifth ice-making temperature in the ice-making chamber is greater than or equal to the second ice-making start-up temperature, the controller controls the valve to switch to the ice-making circuit so that the refrigeration equipment operates in ice-making mode.

[0105] In this embodiment, the first freezing temperature is collected by a freezing temperature sensor corresponding to the freezing chamber, and the fifth ice-making temperature is collected by an ice-making temperature sensor.

[0106] Optionally, the first freezer start-up temperature is a preset threshold. For example, the first freezer start-up temperature is the start-up temperature of the freezer compartment (e.g., -14°C).

[0107] In this embodiment, the second ice-making start-up temperature is lower than the first ice-making start-up temperature. Optionally, the second ice-making start-up temperature is a preset threshold. For example, the first ice-making start-up temperature is the start-up temperature of the ice-making chamber (e.g., -12°C), and the second ice-making start-up temperature is equal to the start-up temperature of the ice-making chamber minus 1 (e.g., -13°C).

[0108] It should be noted that if the third ice-making temperature of the ice-making compartment is greater than or equal to the first ice-making start-up temperature, it indicates that the ice-making compartment requires activation. Therefore, in this solution, the second ice-making start-up temperature is lower than the first ice-making start-up temperature. When the ice-making compartment temperature rises to the second ice-making start-up temperature, it indicates that the ice-making compartment temperature has recovered somewhat, but has not yet reached the required start-up temperature. If the freezer compartment requires activation, the refrigeration system can prioritize cooling the ice-making compartment in advance to lower its temperature, preventing the ice-making compartment from requiring activation alone in a short period of time, thus avoiding frequent compressor starts.

[0109] Step 8012: When the first freezing temperature in the freezing chamber is greater than or equal to the first freezing start-up temperature, and the fifth ice-making temperature in the ice-making chamber is less than the second ice-making start-up temperature, the controller controls the valve to switch to the freezing circuit so that the refrigeration equipment operates in freezing mode.

[0110] It should be understood that if the first freezing temperature of the freezer compartment is greater than or equal to the first freezing start-up temperature, and the fifth ice-making temperature of the ice-making compartment is less than the second ice-making start-up temperature, it means that the freezer compartment meets the start-up conditions and there is no ice-making demand at this time. The valve can be directly controlled to switch to the freezing circuit so that the refrigeration equipment can operate in freezing mode.

[0111] In some embodiments, when the valve is switched to the refrigeration circuit, the controller can control the ice-making fan and the refrigeration fan to turn on.

[0112] It should be understood that, such as Figure 1 , Figure 2 As shown, since the ice-making and refrigeration section of the evaporator is located inside the ice-making evaporator chamber, it can also provide auxiliary cooling to the ice-making compartment during operation in refrigeration mode. Therefore, when the valve is switched to the refrigeration circuit, the ice-making fan and the refrigeration fan can be turned on.

[0113] Furthermore, in any step of this solution involving "switching the valve to the refrigeration circuit", the ice-making fan and the refrigeration fan can be turned on, and this application will not provide examples of each one.

[0114] As can be seen, by implementing the above embodiments, since the ice-making refrigeration section of the refrigeration evaporator is located inside the ice-making evaporator chamber, it can also provide auxiliary cooling to the ice-making chamber during operation in freezing mode. In this solution, when the valve switches to the refrigeration circuit, the ice-making fan and the refrigeration fan are simultaneously turned on, sending the cooling capacity of the refrigeration section into the freezing chamber. At the same time, the cooling capacity generated by the ice-making refrigeration section in the ice-making evaporator chamber is sent into the ice-making chamber via the ice-making fan. This achieves effective cooling of both the freezing chamber and the ice-making chamber simultaneously in freezing mode, thereby reducing the frequency of starting the ice-making mode separately, lowering the number of compressor start-ups and shutdowns, and reducing overall energy consumption.

[0115] Step 8021: When the ice-making room meets the third ice-making shutdown condition, the controller controls the valve to switch from the ice-making circuit to the freezing circuit.

[0116] In this embodiment, the third ice-making shutdown condition is: the sixth ice-making temperature of the ice-making chamber, which is re-collected by the ice-making temperature sensor, is less than the first ice-making shutdown temperature, or the ice-making time of the ice-making chamber is greater than or equal to the second preset time.

[0117] Optionally, the first ice-making shutdown temperature is greater than the second ice-making shutdown temperature, and the first ice-making shutdown temperature is a preset threshold. For example, the first ice-making shutdown temperature is the shutdown temperature of the ice-making chamber (e.g., -15℃), and the second ice-making shutdown temperature is equal to the shutdown temperature of the ice-making chamber minus the preset value.

[0118] Optionally, the second preset duration can be longer than the first preset duration. For example, the second preset duration is the same as the preset duration, such as 30 minutes, while the first preset duration is 15 minutes.

[0119] It should be understood that in the above steps, the temperature of the ice-making compartment that triggers priority ice making is close to its start-up temperature. To maintain a sufficient low temperature for a sufficient period, the ice-making compartment needs to be lowered to a relatively low level to avoid repeated short-term supplemental cooling under refrigeration mode. However, the freezer compartment requires a relatively high start-up temperature, and larger temperature fluctuations in the freezer compartment have a greater impact on food storage than in the refrigeration compartment. Therefore, the priority ice-making shutdown conditions for the freezer compartment when it requires operation differ from those for the refrigeration compartment when it requires operation. When the temperature of the ice-making compartment reaches the first ice-making shutdown temperature (the shutdown temperature of the ice-making compartment), the control valve switches from the ice-making circuit to the freezing circuit to cool the freezer compartment as quickly as possible.

[0120] It should be understood that after the control valve is switched to the refrigeration circuit, such as Figure 2 As shown, the refrigerant flow loop is: compressor-valve-refrigeration evaporator, which provides cooling capacity to the freezer compartment.

[0121] Step 8022: If the ice-making room does not meet the third ice-making shutdown condition, the control valve continues to be connected to the ice-making circuit so that the refrigeration equipment continues to operate in ice-making mode.

[0122] It should be noted that if the ice-making room does not meet the third ice-making shutdown condition, it will continue to operate in ice-making mode until the ice-making room meets the third ice-making shutdown condition, at which point the controller will switch the valve from the ice-making circuit to the freezing circuit.

[0123] Step 8031: When the freezer compartment meets the first freezer shutdown condition and the second refrigeration temperature of the refrigerator compartment is greater than or equal to the first refrigeration shutdown temperature, the controller controls the valve to switch from the freezer circuit to the refrigeration circuit.

[0124] In this embodiment, the first freezer shutdown condition is: the second freezer temperature, re-collected by the freezer temperature sensor, is less than the first freezer shutdown temperature; or, the freezer duration of the freezer compartment is greater than or equal to a third preset duration. Optionally, the first freezer shutdown temperature is a preset threshold. For example, the first freezer shutdown temperature is equal to the freezer compartment shutdown temperature (e.g., -20°C); the third preset duration is 30 minutes.

[0125] It should be understood that freezing time can be interpreted as the continuous operating time accumulated from the moment the freezing mode is entered (i.e., the moment the valve switches to the freezing circuit). To prevent the freezing temperature from failing to reach the target for an extended period due to sensor malfunction or insufficient refrigerant, thus excessively occupying the refrigeration system's operating time, the freezing shutdown condition in this solution includes the freezing time of the freezing compartment being greater than or equal to the preset time.

[0126] In this embodiment of the application, the second refrigeration temperature is collected by a refrigeration temperature sensor corresponding to the refrigeration compartment.

[0127] Optionally, the first refrigerator shutdown temperature is a preset value, for example, the first refrigerator shutdown temperature is equal to the shutdown temperature of the refrigerator compartment (e.g., 2°C).

[0128] It should be noted that if the second refrigeration temperature in the refrigeration compartment is greater than or equal to the first refrigeration shutdown temperature, it indicates that the temperature in the refrigeration compartment has risen. After the freezing mode operation ends, the refrigerant flow path can be switched to the refrigeration circuit to cool down the refrigeration compartment, thereby improving the utilization efficiency of the refrigeration system and avoiding frequent compressor start-stop.

[0129] Step 8032: If the first refrigeration shutdown condition is not met in the refrigeration compartment, the controller controls the valve to remain connected to the refrigeration circuit so that the refrigeration equipment continues to operate in refrigeration mode.

[0130] It should be noted that if the freezer compartment does not meet the first freezer shutdown condition, it will continue to operate in freezer mode until the freezer compartment meets the first freezer shutdown condition, at which point subsequent condition judgments will be made.

[0131] Step 8033: If the freezer compartment does not meet the first freezer shutdown condition, the second refrigeration temperature of the refrigerator compartment is lower than the first refrigeration shutdown temperature, and the ice-making temperature is greater than or equal to the first ice-making shutdown temperature, the controller controls the valve to switch from the freezer circuit to the ice-making circuit.

[0132] In this embodiment of the application, the ice-making temperature is collected by an ice-making temperature sensor.

[0133] Optionally, the first ice-making shutdown temperature is a preset threshold. For example, the first ice-making shutdown temperature is the shutdown temperature of the ice-making chamber (e.g., -15°C).

[0134] It should be noted that if the freezer compartment does not meet the first freezer shutdown condition and the second refrigerator temperature is lower than the first refrigerator shutdown temperature, it indicates that there is no refrigeration demand in the refrigerator compartment after the freezer mode has been activated. In this case, it can be determined whether there is an ice-making demand in the ice-making compartment. If the ice-making temperature is greater than or equal to the first ice-making shutdown temperature, it indicates that the temperature in the ice-making compartment has risen, and there is an ice-making demand. In this case, the valve can be switched from the refrigerator circuit to the ice-making circuit.

[0135] Step 804: When the ice-making room meets the conditions for shutting down the ice-making machine, the controller controls the compressor to stop.

[0136] In this embodiment of the application, the ice-making shutdown condition is: the ice-making temperature of the ice-making chamber, which is re-collected by the ice-making temperature sensor, is less than the second ice-making shutdown temperature, or the ice-making time of the ice-making chamber is greater than or equal to the second preset time.

[0137] For example, the second ice-making shutdown temperature is the shutdown temperature of the ice-making room minus a preset value. For example, the second ice-making shutdown temperature is equal to the shutdown temperature of the ice-making room minus 1, which is -16℃; the second preset duration is 30 minutes.

[0138] By lowering the ice-making chamber to a relatively low level, it is possible to avoid the moment when the temperature of the ice-making chamber rises again in a short period of time, triggering the independent ice-making start-up, thus avoiding frequent compressor start-ups and achieving a balance between ice-making efficiency and overall temperature control stability.

[0139] As can be seen, implementing the above embodiments involves several key steps. First, when the freezer compartment requests to start and the ice-making compartment temperature has risen to a relatively low but intervention-required threshold (such as the second ice-making start-up temperature), the system prioritizes responding to the ice-making request by switching the control valve to the ice-making circuit. This allows the refrigeration equipment to operate in ice-making mode, preventing ice from melting and clumping due to excessive temperature rise, thus ensuring ice quality. It also prevents the ice-making compartment from requesting to start independently in a short period, causing frequent compressor starts. Second, when the ice-making compartment meets the third ice-making shutdown condition, the control valve switches from the ice-making circuit to the freezer circuit, ensuring timely cooling of the freezer compartment after ice-making is completed. Third, when the freezer compartment meets the first freezer shutdown condition, it checks whether the refrigerator compartment temperature has risen. When the second refrigerator compartment temperature is greater than or equal to the first refrigerator shutdown temperature, the control valve switches from the freezer circuit to the refrigerator circuit to cool the refrigerator compartment, thereby improving the utilization efficiency of the refrigeration system and preventing frequent compressor starts and stops. This solution prioritizes ice making, followed by freezing, and finally refrigeration when the freezer compartment requires operation. This approach ensures ice quality, frozen food safety, and refrigeration preservation while significantly improving the robustness and energy efficiency of the refrigeration system.

[0140] 3. The ice-making room must be kept running.

[0141] It should be noted that the ice-making compartment is most sensitive to temperature fluctuations, followed by the freezer compartment. This solution can switch the control valve to the ice-making circuit when the ice-making compartment requires operation, and then determine whether to switch back to the freezer circuit and the refrigerator circuit, thereby making full use of one compressor start-up cycle and improving the operating efficiency of the refrigeration system. Please refer to [link / reference]. Figure 9 , Figure 9 This is a schematic flowchart illustrating another control method for a controller of a refrigeration device disclosed in an embodiment of this application. Figure 9 The control method shown includes the following steps: Step 901: When the seventh ice-making temperature in the ice-making chamber is greater than or equal to the first ice-making start-up temperature, the controller controls the valve to switch to the ice-making circuit so that the refrigeration equipment operates in ice-making mode.

[0142] In this embodiment of the application, the seventh ice-making temperature is collected by an ice-making temperature sensor.

[0143] Optionally, the first ice-making start-up temperature is a preset threshold. For example, the first ice-making start-up temperature is equal to the start-up temperature of the ice-making chamber (e.g., -12°C).

[0144] It should be understood that if the seventh ice-making temperature in the ice-making chamber is greater than or equal to the first ice-making start-up temperature, it means that the ice-making chamber meets the start-up conditions and the control valve can be switched to the ice-making circuit.

[0145] Step 9021: When the ice-making room meets the fourth ice-making shutdown condition and the third freezing temperature is greater than or equal to the first freezing shutdown temperature, the controller controls the valve to switch from the ice-making circuit to the freezing circuit so that the refrigeration equipment operates in freezing mode.

[0146] In this embodiment of the application, the fourth ice-making shutdown condition is: the eighth ice-making temperature of the ice-making chamber, which is re-collected by the ice-making temperature sensor, is less than the first ice-making shutdown temperature, or the ice-making time of the ice-making chamber is greater than or equal to the second preset time.

[0147] Optionally, the first ice-making shutdown temperature is greater than the second ice-making shutdown temperature, and the first ice-making shutdown temperature is a preset threshold. For example, the first ice-making shutdown temperature is the shutdown temperature of the ice-making chamber (e.g., -15℃), and the second ice-making shutdown temperature is equal to the shutdown temperature of the ice-making chamber minus the preset value.

[0148] Optionally, the second preset duration can be longer than the first preset duration. For example, the second preset duration is the same as the preset duration, such as 30 minutes, while the first preset duration is 15 minutes.

[0149] It should be understood that when the ice-making chamber meets the start-up conditions in the above steps, the temperature of the ice-making chamber is relatively high. To achieve a sufficient low-temperature maintenance time, the temperature of the ice-making chamber needs to be lowered to a relatively low level to avoid repeated short-term supplemental cooling under refrigeration mode. Therefore, compared to the ice-making supplemental cooling mode under refrigeration operation and the priority ice-making method when the refrigeration chamber requires start-up, this solution sets a second preset duration and a first ice-making shutdown temperature as shutdown conditions to ensure that the ice-making chamber is sufficiently cooled.

[0150] In this embodiment of the application, the third freezing temperature is collected by the freezing temperature sensor corresponding to the freezing room.

[0151] Optionally, the first freezer shutdown temperature is a preset threshold. For example, the first freezer shutdown temperature is equal to the freezer compartment shutdown temperature (e.g., -20°C).

[0152] It should be understood that if the third freezing temperature is greater than or equal to the first freezing shutdown temperature, it indicates that the temperature of the freezing room has risen slightly. The freezing room temperature can be appropriately controlled to cool down, and the control valve can be switched from the ice-making circuit to the freezing circuit.

[0153] Step 9022: If the ice-making room does not meet the fourth ice-making shutdown condition, the controller controls the valve to remain connected to the ice-making circuit so that the refrigeration equipment continues to operate in ice-making mode.

[0154] It should be noted that if the ice-making room does not meet the fourth ice-making shutdown condition, it will continue to operate in ice-making mode until the ice-making room meets the fourth ice-making shutdown condition, at which point subsequent condition judgments will be made.

[0155] Step 9023: If the ice-making room meets the fourth ice-making shutdown condition and the third freezing temperature is lower than the first freezing shutdown temperature, the controller determines whether the third refrigeration temperature of the refrigeration room is greater than or equal to the first refrigeration shutdown temperature.

[0156] It should be noted that if the ice-making room meets the fourth ice-making shutdown condition and the third freezing temperature is lower than the first freezing shutdown temperature, it means that there is no freezing demand in the freezer room at this time, and it can be further determined whether there is a refrigeration demand in the refrigerator room.

[0157] Step 9031: When the freezer compartment meets the second freezer shutdown condition and the third refrigeration temperature is greater than or equal to the first refrigeration shutdown temperature, the controller controls the valve to switch from the freezer circuit to the refrigeration circuit.

[0158] In this embodiment of the application, the second freezing shutdown condition is: the fourth freezing temperature re-collected by the freezing temperature sensor is less than the second freezing shutdown temperature, or the freezing time of the freezing chamber is greater than or equal to the fourth preset time.

[0159] Optionally, the second freezer shutdown temperature is a preset threshold. For example, the first freezer shutdown temperature is equal to the freezer compartment shutdown temperature minus a preset value, such as equal to the freezer compartment shutdown temperature minus 2 (e.g., -22℃). For example, the fourth preset duration is 30 minutes.

[0160] In this embodiment of the application, the third refrigeration temperature is collected by the refrigeration temperature sensor corresponding to the refrigeration compartment.

[0161] Optionally, the first refrigerator shutdown temperature is a preset threshold. For example, the first refrigerator shutdown temperature is equal to the shutdown temperature of the refrigerator compartment, such as 2°C.

[0162] It should be noted that the temperature threshold (second refrigeration shutdown temperature) involved in the second refrigeration shutdown condition is lower than the shutdown temperature of the refrigeration compartment. By controlling the cooling of the refrigeration compartment, it is possible to avoid the subsequent refrigeration compartment requesting to be turned on separately in a short period of time, which would cause the compressor to start frequently.

[0163] If the third refrigeration temperature is greater than or equal to the first refrigeration shutdown temperature, it indicates that the temperature of the refrigeration compartment has risen slightly. The refrigeration compartment temperature can be appropriately controlled to cool down, and the control valve can be switched from the freezing circuit to the refrigeration circuit.

[0164] Step 9032: If the freezer compartment does not meet the second freezer shutdown conditions, the controller controls the valve to remain connected to the freezer circuit so that the refrigeration equipment continues to operate in freezer mode.

[0165] As can be seen, implementing the above embodiments involves several steps. First, when the ice-making chamber requires startup, the control valve switches to the ice-making circuit, allowing the refrigeration equipment to operate in ice-making mode. This prevents ice from melting and clumping due to excessive temperature rise, ensuring ice quality. Second, after the ice-making chamber meets the fourth ice-making shutdown condition, it is determined whether the freezer chamber requires freezing. When the third freezing temperature is greater than or equal to the first freezing shutdown temperature, the control valve switches from the ice-making circuit to the freezing circuit and operates in freezing mode. This achieves seamless circuit switching without shutting down the compressor, reducing the number of compressor start-ups and shutdowns. Finally, when the freezer chamber meets the second freezing shutdown condition, it is determined whether the refrigerator chamber requires refrigeration. When the third refrigerator temperature is greater than or equal to the first refrigerator shutdown temperature, it indicates a slight temperature rise in the refrigerator chamber. The refrigerator chamber temperature can be appropriately controlled to cool down, and the control valve switches from the freezing circuit to the refrigerator circuit. This solution, by determining whether to switch to the freezing circuit after operating in ice-making mode, and then whether to switch to the refrigerator circuit, fully utilizes one compressor start-up cycle, improving the operating efficiency of the refrigeration system.

[0166] Step 9033: When the freezer compartment meets the second freezer shutdown condition, the third refrigeration temperature is lower than the first refrigeration shutdown temperature, and the ninth ice-making temperature is greater than or equal to the first ice-making shutdown temperature, the controller controls the valve to switch from the freezer circuit to the ice-making circuit so that the refrigeration equipment operates in ice-making mode.

[0167] In this embodiment of the application, the ninth ice-making temperature is collected by an ice-making temperature sensor.

[0168] Optionally, the first ice-making shutdown temperature is a preset threshold. For example, the first ice-making shutdown temperature is the shutdown temperature of the ice-making chamber (e.g., -15°C).

[0169] It should be noted that if the freezer compartment meets the second freezer shutdown condition and the third refrigerator temperature is lower than the first refrigerator shutdown temperature, it indicates that there is no refrigeration demand in the refrigerator compartment after the freezer mode has been running. At this point, it can be determined whether there is an ice-making demand in the ice-making compartment. If the ninth ice-making temperature is greater than or equal to the first ice-making shutdown temperature, it indicates that the temperature in the ice-making compartment has risen, and there is an ice-making demand. In this case, the valve can be switched from the refrigerator circuit to the ice-making circuit.

[0170] Step 904: When the ice-making room meets the fifth ice-making shutdown condition, the controller controls the compressor to stop.

[0171] In this embodiment of the application, the fifth ice-making shutdown condition is: the tenth ice-making temperature of the ice-making chamber, which is re-collected by the ice-making temperature sensor, is less than the second ice-making shutdown temperature, or the ice-making time of the ice-making chamber is greater than or equal to the second preset time.

[0172] For example, the second ice-making shutdown temperature is the shutdown temperature of the ice-making room minus a preset value. For example, the second ice-making shutdown temperature is equal to the shutdown temperature of the ice-making room minus 1, which is -16℃; the second preset duration is 30 minutes.

[0173] By lowering the ice-making chamber to a relatively low level, it is possible to avoid the moment when the temperature of the ice-making chamber rises again in a short period of time, triggering the independent ice-making start-up, thus avoiding frequent compressor start-ups and achieving a balance between ice-making efficiency and overall temperature control stability.

[0174] As can be seen, by implementing the above embodiments, after running in ice-making and freezing modes, it is determined whether there is a refrigeration demand in the refrigerator compartment. If the third refrigerator temperature is lower than the first refrigerator shutdown temperature, it indicates that there is no refrigeration demand in the refrigerator compartment, and at this point, it can be determined whether there is an ice-making demand in the ice-making compartment. If the ninth ice-making temperature is greater than or equal to the first ice-making shutdown temperature, it indicates that the temperature in the ice-making compartment has risen, indicating an ice-making demand, and the valve can be switched from the refrigerator circuit to the ice-making circuit. Simultaneously, by setting a lower second ice-making shutdown temperature (lower than the first ice-making shutdown temperature), a sufficiently low temperature is ensured in the ice-making compartment, allowing the ice to freeze fully and prevent melting and clumping. This solution performs a final check on ice-making demand before the compressor stops, ensuring that the temperature in the ice-making compartment remains stable at a low level, thus achieving overall temperature control performance of the refrigeration equipment.

[0175] When the refrigerator compartment, freezer compartment, or ice-making compartment requests to be turned on, the controller will execute the following actions accordingly. Figures 7-9 The steps are as shown. Especially when the freezer compartment or ice-making compartment requires to be turned on, after the valve is switched to the refrigeration circuit, if the refrigeration compartment meets the shutdown conditions, the compressor will generally be directly controlled to stop. However, considering that both the freezer compartment and the ice-making compartment are extremely sensitive to temperature fluctuations, it is necessary to ensure that both the freezer compartment and the ice-making compartment are at a low level. Therefore, this application determines again whether there is a freezing demand or an ice-making demand before the compressor stops.

[0176] Please see Figure 10 , Figure 10 This is a schematic flowchart illustrating a control method for a controller of a refrigeration device disclosed in an embodiment of this application. Figure 10 The control method shown includes the following steps: Step 1001: If the refrigeration compartment meets the first refrigeration shutdown condition, the controller determines whether the fifth freezing temperature of the freezer compartment is greater than or equal to the first freezing shutdown temperature.

[0177] In this embodiment of the application, the first refrigeration shutdown condition is: the fourth refrigeration temperature collected by the refrigeration temperature sensor corresponding to the refrigeration compartment is less than the first refrigeration shutdown temperature, or the refrigeration time of the refrigeration compartment is greater than or equal to the fifth preset time.

[0178] It should be understood that the refrigeration time can be interpreted as the continuous operating time accumulated from the moment the refrigeration mode is entered (i.e., the moment the valve switches to the refrigeration circuit). To prevent the refrigeration temperature from failing to reach the target for an extended period due to sensor malfunction or insufficient refrigerant, thus excessively occupying the refrigeration system's operating time, the refrigeration shutdown condition in this solution includes a refrigeration time in the refrigeration compartment that is greater than or equal to the preset time.

[0179] Optionally, the first refrigerator shutdown temperature is a preset threshold, such as the first refrigerator shutdown temperature being equal to the shutdown temperature of the refrigerator compartment (2°C).

[0180] For example, the fifth preset duration is 25 minutes. It should be understood that temperature fluctuations in the refrigerator compartment have a relatively small impact on food preservation, allowing for a relatively short single refrigeration cycle. In a single refrigeration process, the time required to drop from the start-up temperature to the shutdown temperature is generally between 15 and 25 minutes. The fifth preset duration can ensure that the refrigerator compartment is sufficiently cooled.

[0181] In this embodiment of the application, the fifth freezing temperature is collected by the freezing temperature sensor corresponding to the freezing room.

[0182] Optionally, the first freezer shutdown temperature is a preset threshold. For example, the first freezer shutdown temperature is equal to the freezer compartment shutdown temperature (e.g., -20°C).

[0183] Step 10021: When the fifth freezing temperature is greater than or equal to the first freezing shutdown temperature, the controller controls the valve to switch from the refrigeration circuit to the freezing circuit.

[0184] It should be understood that if the fifth freezing temperature is greater than or equal to the first freezing shutdown temperature, it indicates that the temperature of the freezing compartment has risen slightly. The freezing compartment temperature can be appropriately controlled to cool down, and the control valve can be switched from the refrigeration circuit to the freezing circuit.

[0185] As can be seen, by implementing the above embodiments, when either the freezer compartment or the ice-making compartment requests to be turned on, after the valve is switched to the refrigeration circuit, if the refrigeration compartment meets the shutdown conditions, considering that both the freezer and ice-making compartments are extremely sensitive to temperature fluctuations, a judgment is made before the compressor stops to determine if there is a freezing demand. This ensures that the temperature of the freezer compartment remains stable at a low level, preventing the freezer compartment from requesting to be turned on independently in a short period of time, thus avoiding frequent compressor starts. When the refrigeration compartment requests to be turned on, after the valve is switched to the refrigeration circuit, if the refrigeration compartment meets the shutdown conditions, the freezing demand of the freezer compartment has not yet been determined. Therefore, after the refrigeration is completed, the freezer compartment is cooled only when there is a cooling demand. This fully utilizes the compressor's single-run time and improves the efficiency of the refrigeration system.

[0186] Step 10022: If the fifth freezing temperature is lower than the first freezing shutdown temperature, the controller determines whether the eleventh ice-making temperature is greater than or equal to the first ice-making shutdown temperature.

[0187] It should be understood that if the fifth freezing temperature is lower than the first freezing shutdown temperature, it indicates that there is no freezing demand at this time, and it can be further determined whether there is a demand for ice making.

[0188] Step 10031: If the freezer compartment meets the third freezer shutdown condition, the controller determines whether the eleventh ice-making temperature is greater than or equal to the first ice-making shutdown temperature.

[0189] In this embodiment, the third freezing shutdown condition is: the sixth freezing temperature re-collected by the freezing temperature sensor is less than the second freezing shutdown temperature, or the freezing time of the freezing chamber is greater than or equal to the sixth preset time, and the eleventh ice-making temperature is collected by the ice-making temperature sensor.

[0190] Optionally, the second freezer shutdown temperature is a preset threshold. For example, the first freezer shutdown temperature is equal to the freezer compartment shutdown temperature minus a preset value, such as equal to the freezer compartment shutdown temperature minus 2 (e.g., -22℃). For example, the sixth preset duration is 30 minutes.

[0191] It should be noted that the temperature threshold (second refrigeration shutdown temperature) involved in the second refrigeration shutdown condition is lower than the shutdown temperature of the refrigeration compartment. By controlling the cooling of the refrigeration compartment, it is possible to avoid the subsequent refrigeration compartment requesting to be turned on separately in a short period of time, which would cause the compressor to start frequently.

[0192] Optionally, the first ice-making shutdown temperature is a preset threshold. For example, the first ice-making shutdown temperature is the shutdown temperature of the ice-making chamber (e.g., -15°C).

[0193] Step 10032: If the freezer compartment does not meet the third freezer shutdown condition, the controller controls the valve to remain connected to the freezer circuit so that the refrigeration equipment continues to operate in freezer mode.

[0194] It should be noted that if the freezer compartment does not meet the third freezer shutdown condition, it will continue to operate in freezer mode until the freezer compartment meets the third freezer shutdown condition, at which point subsequent condition judgments will be made.

[0195] Step 10041: When the eleventh ice-making temperature is greater than or equal to the first ice-making shutdown temperature, the controller controls the valve to switch from the freezing circuit to the ice-making circuit.

[0196] It should be understood that if the eleventh ice-making temperature is greater than or equal to the first ice-making shutdown temperature, it indicates that the temperature of the ice-making chamber has risen slightly. The temperature of the ice-making chamber can be appropriately controlled to cool it down, and the control valve can be switched from the freezing circuit to the ice-making circuit.

[0197] Step 10042: If the eleventh ice-making temperature is lower than the first ice-making shutdown temperature, the controller controls the compressor to stop.

[0198] It should be understood that if the eleventh ice-making temperature is lower than the first ice-making shutdown temperature, it means that there is no need for ice making at this time, and the compressor can be directly shut down.

[0199] Step 10051: When the ice-making room meets the sixth ice-making shutdown condition, the controller controls the compressor to stop.

[0200] In this embodiment, the sixth ice-making shutdown condition is: the twelfth ice-making temperature of the ice-making chamber, which is re-collected by the ice-making temperature sensor, is less than the second ice-making shutdown temperature, or the ice-making time of the ice-making chamber is greater than or equal to the second preset time.

[0201] Optionally, the second ice-making shutdown temperature is a preset threshold. For example, it is equal to the shutdown temperature of the ice-making chamber minus a preset value. For instance, the second ice-making shutdown temperature is equal to the shutdown temperature of the ice-making chamber minus 1, which is -16℃.

[0202] By lowering the ice-making chamber to a relatively low level, it is possible to avoid the moment when the temperature of the ice-making chamber rises again in a short period of time, triggering the independent ice-making start-up, thus avoiding frequent compressor start-ups and achieving a balance between ice-making efficiency and overall temperature control stability.

[0203] Step 10052: If the ice-making room does not meet the sixth ice-making shutdown condition, the controller controls the valve to remain connected to the ice-making circuit so that the refrigeration equipment continues to operate in ice-making mode.

[0204] It should be noted that if the ice-making chamber does not meet the sixth ice-making shutdown condition, it will continue to operate in ice-making mode until the ice-making chamber meets the sixth ice-making shutdown condition and the compressor is controlled to stop.

[0205] As can be seen, by implementing the above embodiments, considering that the ice-making room is extremely sensitive to temperature fluctuations, the final step before the compressor stops is to determine whether there is an ice-making demand, ensuring that the temperature of the ice-making room is stable at a low level, guaranteeing ice-making quality, avoiding the ice-making room from requesting to start up alone in a short period of time, causing the compressor to start up frequently, and at the same time, making full use of the compressor's single start-up time and improving the utilization efficiency of the refrigeration system.
