Description

Technical Field

[0001] This application relates to refrigeration technology, and more particularly to a refrigeration control method and a refrigerator. Background Technology

[0002] A refrigerator is an essential household appliance. It typically consists of a cabinet and an inner liner. An insulation structure separates the liner from the cabinet to reduce cold air loss and thus lower energy consumption. The storage space of a refrigerator usually includes a refrigerator compartment and a freezer compartment; some refrigerators also have a variable temperature compartment. Shelves or drawers can be installed within each storage compartment to divide it into multiple storage areas.

[0003] In typical refrigerators, the evaporator, refrigerator fan, refrigerator damper, and air vents are located at the back of the refrigerator compartment. When the refrigerator fan is activated and the damper is open, the cooling energy generated by the evaporator is delivered into the refrigerator compartment via the air vents. Technicians have observed that even after cooling is stopped, the temperature inside the refrigerator compartment continues to drop significantly, resulting in excessively low temperatures, particularly near the air vents where the temperature can fall more than 3°C below the preset temperature. This causes food in that area to freeze easily.

[0004] Furthermore, cold storage compartments typically only have one air vent and one refrigerated air damper, which controls the flow of cold air from the vent into the compartment. Areas closer to the vent are cooler, while areas farther away are warmer, resulting in uneven temperature distribution and poor preservation. Additionally, because hot air rises, the upper areas of the cold storage compartment experience greater temperature fluctuations and more significant temperature changes, which is also detrimental to food preservation.

[0005] Furthermore, some variable temperature compartments are located within the refrigeration room, serving as sub-functional zones within the refrigeration room. This is equivalent to the refrigeration room being divided into a large space and sub-functional zones, with the target temperature of the sub-functional zones being lower than that of the surrounding large space. In existing solutions, the sub-functional zones and the large space start cooling simultaneously. When cooling ends, the temperature in the sub-functional zones cannot reach a lower level, thus failing to achieve a good preservation effect. Extending the cooling time can lead to over-cooling in the large space, causing food to freeze. Summary of the Invention

Detailed Implementation

[0013] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0014] A refrigerator is an essential household appliance. It typically consists of a cabinet and an inner liner. An insulation structure separates the liner from the cabinet to reduce cold air loss and thus lower energy consumption. The storage space of a refrigerator usually includes a refrigerator compartment and a freezer compartment; some refrigerators also have a variable temperature compartment. Shelves or drawers can be installed within each storage compartment to divide it into multiple storage areas.

[0015] In typical refrigerators, the evaporator, refrigerator fan, refrigerator damper, and air vents are located at the back of the refrigerator compartment. When the refrigerator fan is activated and the damper is open, the cooling energy generated by the evaporator is delivered into the refrigerator compartment via the air vents. Technicians have discovered that even after cooling is stopped, the temperature inside the refrigerator compartment continues to drop significantly, exhibiting a considerable lag. This results in excessively low temperatures, particularly near the air vents, where the temperature can fall more than 3°C below the preset temperature, causing food in that area to freeze easily.

[0016] Furthermore, cold storage compartments typically only have one air vent and one refrigerated air damper, which controls the flow of cold air from the vent into the compartment. Areas closer to the vent are cooler, while areas farther away are warmer, resulting in uneven temperature distribution and poor preservation. Additionally, because hot air rises, the upper areas of the cold storage compartment experience greater temperature fluctuations and more significant temperature changes, which is also detrimental to food preservation.

[0017] Furthermore, some variable temperature compartments are located within the refrigeration room, serving as sub-functional zones within the refrigeration room. This is equivalent to the refrigeration room being divided into a large space and sub-functional zones, with the target temperature of the sub-functional zones being lower than that of the surrounding large space. In existing solutions, the sub-functional zones and the large space start cooling simultaneously. When cooling ends, the temperature in the sub-functional zones cannot reach a lower level, thus failing to achieve a good preservation effect. Extending the cooling time can lead to over-cooling in the large space, causing food to freeze.

[0018] Based on the above problems, this embodiment provides a refrigeration control method and a refrigerator, which can improve the problem that the temperature of the sub-functional area cannot reach a lower target temperature.

[0019] The refrigerator provided in this embodiment can be a double-door refrigerator, with the upper and lower doors being a refrigerator compartment and a freezer compartment, respectively. The refrigerator compartment is divided into a large space area and sub-functional areas.

[0020] The refrigerator can also be configured with double doors on both sides, a French door, or other designs. It can also have a double door upper section and a drawer lower section. This embodiment does not impose any limitations.

[0021] Example 1.

[0022] like Figure 1As shown, the refrigerator provided in this embodiment includes: a cabinet 10, with a top-opening door 20 and a bottom-opening door 30 at the front end of the cabinet 10, corresponding to the refrigerator compartment and the freezer compartment respectively. A variable temperature drawer can be installed in the refrigerator compartment as a sub-functional area. Figure 1 The top-opening door 20 is a single-leaf door.

[0023] Figure 2 The top-hinged door 20 is shown in its open state. Figure 2 The top door is a double door. The refrigerator liner is located inside the cabinet 10, and an insulation structure is installed between the refrigerator liner and the cabinet 10 to form a refrigerator space. Figure 2 The inner liner or insulation structure is not shown.

[0024] A refrigeration evaporator and a refrigeration fan 40 are installed on the rear of the refrigerator compartment, with air outlets on both sides. A refrigeration damper is installed in the air duct at the front end of each air outlet. A return air vent 60 is installed on the lower rear of the refrigerator compartment. The refrigeration evaporator generates cooling, lowering the ambient air temperature to create cold air. When the refrigeration fan 40 starts, it opens the refrigeration damper, driving the cold air in the air duct from the air outlets into the refrigerated space for cooling.

[0025] In this embodiment, as Figure 4 As shown, this embodiment provides a refrigeration control method, including: Step 101: When entering the refrigeration state, the refrigeration evaporator generates cold energy and delivers the cold energy to the large space area and sub-functional areas.

[0026] Specifically, when the temperature inside the cold storage room exceeds the preset value, the refrigeration system switches to cold storage mode. Refrigerant flows through the cold storage evaporator, which generates cooling capacity. The refrigeration fan starts, delivering the cooling capacity to the large space and sub-functional areas of the cold storage room.

[0027] Step 102: When the refrigeration in the cold storage room ends, the refrigeration evaporator stops generating cold energy; only the remaining cold energy of the refrigeration evaporator is transferred to the sub-functional area.

[0028] When the refrigerator compartment is in cooling mode, its temperature gradually decreases. Once the target temperature is reached, the cooling process stops (e.g., switching to freezing mode), and the evaporator stops producing cooling. However, the evaporator and the cooling fan continue to operate. At this point, the evaporator's temperature is lower, and the remaining cooling capacity is supplied to the sub-functional areas to further lower their temperatures, reducing the rate of temperature recovery and effectively avoiding frequent cooling demands, thus reducing energy consumption. Stopping the supply of cooling to larger spaces prevents excessive cooling and food freezing.

[0029] Step 103: When the supplemental cooling conditions are met, only the remaining cooling capacity of the refrigeration evaporator is transferred to the upper part of the large space area.

[0030] In the above steps, while continuing to supply cooling capacity to the sub-functional area, the supplementary cooling conditions are monitored and judged. When the supplementary cooling conditions are met, the supply of cooling capacity to the sub-functional area is stopped, and the remaining cooling capacity of the refrigeration evaporator is supplied to the upper part of the large space area.

[0031] Specifically, during refrigerator operation, heat loss causes the temperature of the large compartment to rise, especially the upper part of the large compartment where the temperature rises faster; or when a user puts new items into the large compartment, these new items act as heat sources, further raising the temperature. Therefore, the duration and temperature of the large compartment can be determined as restart conditions. For example, if the temperature of the upper part of the large compartment exceeds a certain value, the restart condition is considered met; or in step 102, cooling capacity is continued to be supplied to the sub-functional area for a period of time, and the restart condition is considered met after that time.

[0032] It can also monitor and judge the temperature of sub-functional areas. For example, when the temperature of a sub-functional area drops to the preset temperature, it is considered that the restart conditions are met.

[0033] Once the restart conditions are met, the supply of cooling energy to the sub-functional areas is stopped to prevent excessive cooling and food freezing. Then, the supply of cooling energy to the upper part of the large space area is resumed to replenish the lost cooling energy and improve the food preservation effect in that area.

[0034] Step 104: When the temperature of the refrigeration evaporator reaches the preset first upper limit value, close the air supply channel between the refrigeration evaporator and the large space area and sub-functional area.

[0035] During steps 102 and 103 above, the refrigeration evaporator does not generate new cooling capacity, and its temperature gradually increases. The temperature of the refrigeration evaporator is monitored. If the temperature of the refrigeration evaporator rises to a preset first upper limit value T, for example, higher than the required temperature of the refrigeration room by 4°C or 5°C, and the "hot air" does not meet the cooling capacity requirements of the refrigeration room, the air supply channel between the refrigeration evaporator and the large space area and sub-functional areas is closed to prevent "hot air" from entering the large space area and sub-functional areas.

[0036] The technical solution provided in this embodiment includes a refrigeration control method comprising: when entering the refrigeration state, the refrigeration evaporator generates cooling capacity and delivers the cooling capacity to the large space area and sub-functional areas; when the refrigeration of the refrigeration compartment ends, the refrigeration evaporator stops generating cooling capacity; only the remaining cooling capacity of the refrigeration evaporator is delivered to the sub-functional areas; when the supplementary refrigeration conditions are met, only the remaining cooling capacity of the refrigeration evaporator is delivered to the upper part of the large space area; when the temperature of the refrigeration evaporator reaches a preset first upper limit value, the air supply channel between the refrigeration evaporator and the large space area and sub-functional areas is closed, thereby realizing that when the refrigeration ends, the remaining cooling capacity of the refrigeration evaporator is delivered to the sub-functional areas to meet the cooling needs of the lower-temperature sub-functional areas; and further providing cooling capacity to the upper area of ​​the large space area, improving the problem of rapid temperature rise and large temperature fluctuation in this area, thereby improving the preservation effect.

[0037] Example 2.

[0038] This embodiment optimizes the refrigerator and refrigeration control method based on the above embodiments.

[0039] This embodiment provides a specific implementation of a refrigerator: the large space area is provided with at least two air outlets from top to bottom; the sub-functional area is provided with air outlets; each air outlet is connected to an air supply channel, and all air supply channels converge to connect with the main air duct, which is equipped with a refrigeration fan.

[0040] It is also equipped with a first air damper, a second air damper and a third air damper. The first air damper is used to control the opening and closing of the air supply channel corresponding to the lower air supply outlet of the large space area; the second air damper is used to control the opening and closing of the air supply channel corresponding to the upper air supply outlet of the large space area; and the third air damper is used to control the opening and closing of the air supply channel corresponding to the air supply outlet of the sub-functional area.

[0041] In step 101 above, when entering the refrigeration state, the refrigeration evaporator generates cold energy and delivers the cold energy to the large space area and sub-functional area. Specifically, this may include: opening the first air damper, the second air damper, and the third air damper, and starting the refrigeration fan to deliver the cold energy generated by the refrigeration evaporator to the large space area and sub-functional area.

[0042] In step 102 above, when the refrigeration of the cold storage room ends, the refrigeration evaporator stops generating cold energy; only the remaining cold energy of the refrigeration evaporator is delivered to the sub-functional area. Specifically, the first and second air dampers are closed, the third air damper remains open, the refrigeration fan continues to work, and the remaining cold energy of the refrigeration evaporator is delivered only to the sub-functional area.

[0043] In step 103 above, when the supplementary refrigeration conditions are met, only the remaining cold energy of the refrigeration evaporator is delivered to the upper part of the large space area. Specifically, the third air damper is closed, the second air damper is reopened, the first air damper remains closed, and the refrigeration fan continues to work to deliver only the remaining cold energy of the refrigeration evaporator to the upper part of the large space area.

[0044] In step 104 above, when the temperature of the refrigeration evaporator reaches the preset first upper limit value, the air supply channel between the refrigeration evaporator and the large space area and sub-functional area is closed, and the refrigeration fan and each air damper are turned off. Specifically, the first air damper, the second air damper, and the third air damper are all closed, and the refrigeration fan is stopped.

[0045] Example 3.

[0046] This embodiment optimizes the refrigerator and refrigeration control method based on the above embodiments.

[0047] This embodiment provides a specific implementation method for a refrigerator: as follows Figure 2 and Figure 3 As shown, the left side of the large space area has three air outlets from top to bottom: the first air outlet 51, the second air outlet 52, and the third air outlet 53, located at the upper, middle, and lower parts of the left side of the large space area, respectively. The right side of the large space area has three air outlets from top to bottom: the fourth air outlet 54, the fifth air outlet 55, and the sixth air outlet 56, located at the upper, middle, and lower parts of the right side of the large space area, respectively. A seventh air outlet 57 is provided for the sub-functional area.

[0048] Of the seven air outlets mentioned above, each outlet is connected to a corresponding air supply channel, for a total of seven air supply channels: the first air supply channel 81 connects to the first air outlet 51, the second air supply channel 82 connects to the second air outlet 52, the third air supply channel 83 connects to the third air outlet 53, the fourth air supply channel 84 connects to the fourth air outlet 54, the fifth air supply channel 85 connects to the fifth air outlet 55, the sixth air supply channel 86 connects to the sixth air outlet 56, and the seventh air supply channel 87 connects to the seventh air outlet 57. The seven air supply channels converge and connect to the main air duct 80. A refrigeration fan 40 is installed inside the main air duct 80. When the refrigeration fan 40 is turned on, cold air is directed vertically from the main air duct 80 to each air supply channel, and then delivered out from the corresponding air outlet.

[0049] The first damper 91 is located at the junction of the second air supply channel 82 and the third air supply channel 83 corresponding to the second air supply outlet 52 and the third air supply outlet 53 with the main air duct 80. The first damper 91 is used to control the opening and closing of the second air supply channel 82 and the third air supply channel 83.

[0050] The second damper 92 is located at the junction of the first air supply channel 81 and the fourth air supply channel 84 with the main air duct 80, corresponding to the first air supply outlet 51 and the fourth air supply outlet 54. The second damper 92 is used to control the opening and closing of the first air supply channel 81 and the fourth air supply channel 84.

[0051] The third damper 93 is located at the junction of the seventh air supply channel 87 and the main air duct 80 corresponding to the seventh air supply outlet 57. The third damper 93 is used to control the opening and closing of the seventh air supply channel 87.

[0052] It also includes: a fourth damper 94, located at the junction of the fifth air supply channel 85 and the sixth air supply channel 86, corresponding to the fifth air supply outlet 55 and the sixth air supply outlet 56, and the main air duct 80; and a third damper 93 used to control the opening and closing of the fifth air supply channel 85 and the sixth air supply channel 86. The fourth damper 94 and the first damper 91 can open and close synchronously.

[0053] In step 101 above, when entering the refrigeration state, the refrigeration evaporator generates cold energy and delivers the cold energy to the large space area and sub-functional area. Specifically, this may include: opening the first air damper 91, the second air damper 92, the third air damper 93, and the fourth air damper 94, and starting the refrigeration fan 40 to deliver the cold energy generated by the refrigeration evaporator to the large space area and sub-functional area.

[0054] In step 102 above, when the refrigeration of the cold storage compartment ends, the refrigeration evaporator stops generating cold energy; only the remaining cold energy of the refrigeration evaporator is delivered to the sub-functional area, specifically by closing the first air damper 91, the second air damper 92 and the fourth air damper 94, keeping the third air damper 93 open, and the refrigeration fan 40 continues to work to deliver the remaining cold energy to the sub-functional area.

[0055] In step 103 above, when the supplementary refrigeration conditions are met, only the remaining cold energy of the refrigeration evaporator is delivered to the upper part of the large space area. Specifically, the third air damper 93 is closed, the second air damper 92 is reopened, the first air damper 91 and the fourth air damper 94 remain closed, and the refrigeration fan 40 continues to work to deliver the remaining cold energy to the upper part of the large space area.

[0056] In step 104 above, when the temperature of the refrigeration evaporator reaches the preset first upper limit value, the air supply channel between the refrigeration evaporator and the large space area and sub-functional area is closed. Specifically, the first air damper 91, the second air damper 92, the third air damper 93 and the fourth air damper 94 are all closed, and the refrigeration fan 40 is stopped.

[0057] Example 4.

[0058] This embodiment optimizes the refrigeration control method of the refrigerator based on the above embodiment.

[0059] In step 101 above, when entering the refrigeration state, cold energy is delivered to the large space area and sub-functional area for refrigeration, including: when it is detected that at least one of the large space area and sub-functional area has a refrigeration demand, the refrigeration state is switched.

[0060] like Figure 5As shown, this embodiment provides an implementation method: when a cooling demand is detected in a large space area, the valves in the refrigeration system switch to the refrigeration state, the first damper 91, the second damper 92 and the fourth damper 94 are opened, and the refrigeration fan 40 is started to deliver cooling capacity to the large space area for cooling.

[0061] During the process of delivering cooling capacity to the large space area, when a cooling demand is detected in a sub-functional area, the third air damper 93 is opened to deliver cooling capacity to the sub-functional area for cooling.

[0062] Then continue with the following steps: Step 102: When the refrigeration in the cold storage room ends, the refrigeration evaporator stops generating cold energy; only the remaining cold energy of the refrigeration evaporator is transferred to the sub-functional area.

[0063] Specifically, the electric valve switches to the refrigeration mode, and the refrigeration evaporator stops generating new cooling capacity.

[0064] The first air damper 91, the second air damper 92, and the fourth air damper 94 are closed, while the third air damper 93 remains open. The refrigeration fan 40 continues to operate, delivering the remaining cooling capacity to the sub-functional area.

[0065] Step 103: When the supplemental cooling conditions are met, only the remaining cooling capacity of the refrigeration evaporator is transferred to the upper part of the large space area.

[0066] Specifically, the third air damper 93 is closed, the second air damper 92 is reopened, the first air damper 91 and the fourth air damper 94 remain closed, and the refrigeration fan 40 continues to work to deliver the remaining cold energy to the upper part of the large space area.

[0067] Step 104: When the temperature of the refrigeration evaporator reaches the preset first upper limit value, close the air supply channel between the refrigeration evaporator and the large space area and sub-functional area.

[0068] Specifically, when the temperature of the refrigeration evaporator reaches the preset first upper limit value T, the first air damper 91, the second air damper 92, the third air damper 93, and the fourth air damper 94 are all closed, and the refrigeration fan 40 is stopped.

[0069] The specific methods for each of the above steps can be referred to in the above embodiments, and will not be repeated in this embodiment.

[0070] Example 5.

[0071] This embodiment optimizes the refrigeration control method of the refrigerator based on the above embodiment.

[0072] In step 101 above, when entering the refrigeration state, cold energy is delivered to the large space area and sub-functional area for refrigeration, including: when it is detected that at least one of the large space area and sub-functional area has a refrigeration demand, the refrigeration state is switched.

[0073] like Figure 6 As shown, this embodiment provides an implementation method: when a cooling demand is detected in the sub-functional area, the electric valve switches to the refrigeration state, and the refrigeration evaporator generates cooling capacity; the third air damper 93 is opened, and the refrigeration fan is turned on to deliver cooling capacity to the sub-functional area for refrigeration.

[0074] During the process of delivering cooling capacity to the sub-functional areas, when a cooling demand is detected in the large space area, the first damper 91, the second damper 92, and the fourth damper 94 are opened to deliver cooling capacity to the large space area for cooling.

[0075] Then continue with the following steps: Step 102: When the refrigeration in the cold storage room ends, the refrigeration evaporator stops generating cold energy; only the remaining cold energy of the refrigeration evaporator is transferred to the sub-functional area.

[0076] Specifically, the electric valve switches to the refrigeration mode, and the refrigeration evaporator stops generating new cooling capacity.

[0077] The first air damper 91, the second air damper 92, and the fourth air damper 94 are closed, while the third air damper 93 remains open. The refrigeration fan 40 continues to operate, delivering the remaining cooling capacity to the sub-functional area.

[0078] Step 103: When the supplemental cooling conditions are met, only the remaining cooling capacity of the refrigeration evaporator is transferred to the upper part of the large space area.

[0079] Specifically, the third air damper 93 is closed, the second air damper 92 is reopened, the first air damper 91 and the fourth air damper 94 remain closed, and the refrigeration fan 40 continues to work to deliver the remaining cold energy to the upper part of the large space area.

[0080] Step 104: When the temperature of the refrigeration evaporator reaches the preset first upper limit value, close the air supply channel between the refrigeration evaporator and the large space area and sub-functional area.

[0081] Specifically, when the temperature of the refrigeration evaporator reaches the preset first upper limit value T, the first air damper 91, the second air damper 92, the third air damper 93, and the fourth air damper 94 are all closed, and the refrigeration fan 40 is stopped.

[0082] The specific methods for each of the above steps can be referred to in the above embodiments, and will not be repeated in this embodiment.

[0083] Based on the above scheme, in step 101, during the process of supplying cooling capacity to the sub-functional areas, if there is no cooling demand in the large space area, the temperature of the large space area is monitored. If the temperature of the large space area is between the start-up and stop points, the second air damper 92 is opened and maintained for t1 minutes, so that during the process of supplying cooling capacity to the sub-functional areas, cooling capacity is also supplied to the upper part of the large space area.

[0084] After the preset time t1 minutes have elapsed, or after the refrigeration of the cold storage compartment has ended, the third air damper 93 will be closed, and the cold energy will no longer be supplied to the sub-functional area, but will continue to be supplied to the upper part of the large space area to ensure that the temperature of the upper part of the large space area meets the preset requirements and improve the food preservation effect.

[0085] Example 6.

[0086] This embodiment optimizes the refrigeration control method of the refrigerator based on the above embodiment.

[0087] The difference from the above embodiments is that the supplementary cooling conditions are specifically defined: Step 101: When entering the refrigeration state, the refrigeration evaporator generates cold energy and delivers the cold energy to the large space area and sub-functional areas.

[0088] Specifically, when the temperature inside the cold storage room exceeds the preset value, the refrigeration system switches to cold storage mode. Refrigerant flows through the cold storage evaporator, which generates cooling capacity. The refrigeration fan starts, delivering the cooling capacity to the large space and sub-functional areas of the cold storage room.

[0089] Step 102: When the refrigeration in the cold storage room ends, the refrigeration evaporator stops generating cold energy; only the remaining cold energy of the refrigeration evaporator is transferred to the sub-functional area.

[0090] When the refrigerator compartment is in cooling mode, its temperature gradually decreases. Once the target temperature is reached, the cooling process stops (e.g., switching to freezing mode), and the evaporator stops producing cooling. However, the evaporator and the cooling fan continue to operate, delivering the remaining cooling energy to the sub-functional areas to keep their temperatures dropping until the target temperature is reached. Stopping the delivery of cooling to the larger space prevents excessive cooling and thus avoids food freezing.

[0091] Step 103: When the supplemental cooling conditions are met, only the remaining cooling capacity of the refrigeration evaporator is transferred to the upper part of the large space area.

[0092] In the above steps, while continuing to supply cooling capacity to the sub-functional area, the supplementary cooling conditions are monitored and judged. When the supplementary cooling conditions are met, the supply of cooling capacity to the sub-functional area is stopped, and the remaining cooling capacity of the refrigeration evaporator is supplied to the upper part of the large space area.

[0093] Specifically, when the refrigeration in the cold storage compartment ends, the evaporator stops generating cooling capacity; only the remaining cooling capacity of the evaporator is transferred to the sub-functional areas for a preset time. When the preset time is up, it is considered that the supplementary refrigeration conditions have been met.

[0094] The condition for supplemental cooling is met when the preset time is reached. After the condition for supplemental cooling is met, the remaining cold energy from the refrigeration evaporator is no longer supplied to the sub-functional area. Instead, the cold energy is switched to the upper part of the large space area to replenish the cold energy lost in the upper part of the large space area, thereby improving the food preservation effect in that area.

[0095] Step 104: When the temperature of the refrigeration evaporator reaches the preset first upper limit value, close the air supply channel between the refrigeration evaporator and the large space area and sub-functional area.

[0096] Example 7.

[0097] This embodiment optimizes the refrigeration control method of the refrigerator based on the above embodiment.

[0098] The difference from the above embodiments is that the supplementary cooling conditions are specifically defined: Step 101: When entering the refrigeration state, the refrigeration evaporator generates cold energy and delivers the cold energy to the large space area and sub-functional areas.

[0099] Specifically, when the temperature inside the cold storage room exceeds the preset value, the refrigeration system switches to cold storage mode. Refrigerant flows through the cold storage evaporator, which generates cooling capacity. The refrigeration fan starts, delivering the cooling capacity to the large space and sub-functional areas of the cold storage room.

[0100] Step 102: When the refrigeration in the cold storage room ends, the refrigeration evaporator stops generating cold energy; only the remaining cold energy of the refrigeration evaporator is transferred to the sub-functional area.

[0101] When the refrigerator compartment is in cooling mode, its temperature gradually decreases. Once the target temperature is reached, the cooling process stops (e.g., switching to freezing mode), and the evaporator stops producing cooling. However, the evaporator and the cooling fan continue to operate, delivering the remaining cooling energy to the sub-functional areas to keep their temperatures dropping until the target temperature is reached. Stopping the delivery of cooling to the larger space prevents excessive cooling and thus avoids food freezing.

[0102] Step 103: When the supplemental cooling conditions are met, only the remaining cooling capacity of the refrigeration evaporator is transferred to the upper part of the large space area.

[0103] In the above steps, while continuing to supply cooling capacity to the sub-functional area, the supplementary cooling conditions are monitored and judged. When the supplementary cooling conditions are met, the supply of cooling capacity to the sub-functional area is stopped, and the remaining cooling capacity of the refrigeration evaporator is supplied to the upper part of the large space area.

[0104] Specifically, when the refrigeration in the cold storage compartment ends, the evaporator stops generating cooling capacity; only the remaining cooling capacity of the evaporator is supplied to the sub-functional areas, and the temperature of the sub-functional areas or the upper part of the large space area is monitored. When the temperature of the sub-functional area drops to the first preset value or the temperature of the upper part of the large space area rises to the second preset value, the supplementary cooling conditions are considered to be met.

[0105] Once the additional cooling conditions are met, the remaining cold energy from the refrigeration evaporator is no longer supplied to the sub-functional area. Instead, the cold energy is switched to the upper part of the large space area to replenish the cold energy lost in the upper part of the large space area, thereby improving the food preservation effect in that area.

[0106] Step 104: When the temperature of the refrigeration evaporator reaches the preset first upper limit value, close the air supply channel between the refrigeration evaporator and the large space area and sub-functional area.
