Description

Technical Field

[0001] This application relates to the field of food preservation technology, and in particular to a food preservation refrigerator and its working method, electronic equipment and storage medium. Background Technology

[0002] Common methods for preserving fresh meat include refrigeration, soft freezing, and freezing. Refrigeration has a shorter preservation time, while frozen meat has a poor texture and requires thawing. Therefore, soft freezing is a more suitable method for meat preservation. Soft freezing can extend the shelf life of meat to 1-2 weeks, minimize nutrient loss, and allow for further processing without thawing. However, existing soft freezing technology has certain problems. The refrigerator's cooling system delivers low-temperature air to the soft-freezing area to remove heat, thus lowering the entire soft-freezing area and the stored meat to the preset temperature. During this process, the low humidity of the low-temperature air leads to a decrease in humidity inside the soft-freezing area. When the cold air directly contacts unpackaged meat, it causes the surface to dry out. Over time, this results in dehydration loss, leading not only to a deterioration in the appearance of the meat but also accelerating the spoilage process.

[0003] Therefore, some technologies propose using indirect cooling, where cold air is not directly blown into the soft-freeze compartment. This solution effectively avoids the desiccation loss caused by direct cold air. However, new problems still arise during long-term use. Each time a user opens the soft-freeze compartment to store meat, moisture from the outside air enters and accumulates inside due to the lower internal temperature compared to the outside air. Since the soft-freeze compartment is below freezing, frost and ice buildup similar to those in direct-cooling refrigerators can occur inside. Frost and ice buildup reduce cooling efficiency and can even make drawers difficult to open, causing inconvenience. Furthermore, the internal temperature rises each time meat is accessed, and the slower cooling rate of indirect cooling can cause the surface of the stored meat to thaw and melt. Repeated temperature fluctuations can also cause recrystallization in the meat, further reducing the preservation effect of soft freezing. The freezing area for long-term storage of meat is generally frozen at -18°C or lower, and the freezing area is usually controlled by air cooling. As a result, the freezing area also has the problem of low environmental humidity and meat is prone to drying out.

[0004] To address the aforementioned issues, this solution establishes a special channel (such as an electric damper) between the soft-freezing zone and the freezer compartment. This allows for heat and moisture transfer between the two zones when the channel is open. By controlling the opening and closing of the channel, excess moisture in the soft-freezing zone is promptly drained into the freezer compartment, where air convection rapidly lowers the temperature. Simultaneously, water can be added to the freezer compartment, increasing its humidity and reducing dryness to some extent. Summary of the Invention

[0005] This application provides a refrigerator with a working method, electronic device, and storage medium to solve the above-mentioned technical problems.

[0006] In a first aspect, this application provides a refrigerator for preserving food, which includes a cabinet, wherein the cabinet is provided with a freezer compartment and a soft-freeze compartment, and the refrigerator further includes:

[0007] The refrigeration module includes an air-cooling system and a cooling structure disposed in the soft-freezing chamber. The air-cooling system is configured to control the temperature in the freezing chamber using an air-cooling method. The air-cooling system is used to transfer cold energy to the cooling structure. The cooling structure is configured to control the temperature in the soft-freezing chamber using a direct cooling method.

[0008] A connecting passage is located inside the housing, with its two ends connecting the freezing chamber and the soft freezing chamber, respectively. A first damper for controlling the opening and closing of the connecting passage is provided inside the connecting passage.

[0009] Furthermore, the cooling structure is a soft-freezing air duct, and the cold air generated by the air-cooling system can circulate within the soft-freezing air duct.

[0010] Furthermore, the soft-freezing air duct is arranged in a U-shape within the soft-freezing room.

[0011] Furthermore, a second damper is provided between the soft-freezing air duct and the air-cooling system.

[0012] Furthermore, the soft-freezing room is equipped with a first temperature sensor and a humidity sensor.

[0015] Secondly, this application provides a method for operating a food preservation refrigerator, the method comprising:

[0016] After detecting that the soft-freezing compartment has been opened, monitor in real time whether the soft-freezing compartment has been closed;

[0017] When the soft-freezing compartment is closed, the temperature inside the soft-freezing compartment is recorded as the first temperature T1, the humidity inside the soft-freezing compartment is recorded as the first humidity H1, and the temperature inside the freezing compartment is recorded as the second temperature t0.

[0018] The air-cooling system controls the temperature inside the freezer room to drop from the second temperature t0 to the third temperature T2;

[0019] Controlling the opening and closing of the connecting channel and the soft-freezing air duct ensures that the temperature inside the soft-freezing room reaches a preset temperature T0, and the humidity inside the soft-freezing room reaches a preset humidity H0.

[0022] When the soft-freezing air duct is closed and the connecting channel is opened, both the temperature and humidity inside the soft-freezing room decrease.

[0023] Based on the priority of the temperature in the soft-freezing room reaching a preset temperature T0 and the humidity in the soft-freezing room reaching a preset humidity H0, it is determined whether the soft-freezing air duct should be opened.

[0024] Furthermore, the process of determining whether to open the soft-freezing air duct based on the priority of the temperature in the soft-freezing room reaching a preset temperature T0 and the humidity in the soft-freezing room reaching a preset humidity H0 includes:

[0025] If the temperature inside the soft-freezing room reaches the preset temperature T0 first, the connecting channel is closed. When the temperature inside the soft-freezing room rises back to T0+ΔT, the connecting channel is reopened. After the temperature inside the soft-freezing room drops back to the preset temperature T0, the connecting channel is closed again. This cycle continues until the humidity inside the soft-freezing room reaches the preset humidity H0, where 0.1℃≤ΔT≤1.5℃.

[0026] Furthermore, the process of determining whether to open the soft-freezing air duct based on the priority of the temperature in the soft-freezing room reaching a preset temperature T0 and the humidity in the soft-freezing room reaching a preset humidity H0 includes:

[0027] If the humidity in the soft-freezing room reaches the preset humidity H0 first, the connecting channel is closed and the soft-freezing air duct is opened. After the temperature in the soft-freezing room reaches the preset temperature T0, the soft-freezing air duct is closed.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0049] In the embodiments of this application, such as Figure 1As shown, the basic structure of a refrigerator includes at least a cabinet 1, storage compartments, a compressor 2, an evaporator 3, and a cooling system. The storage compartments can be at least one of a freezer compartment 102, a refrigerator compartment 101, a soft-freeze compartment 103, and a ripening compartment. The evaporator 3 is located in an evaporator cavity 107 and is connected to the compressor 2 via a refrigerant circulation pipeline. The evaporator 3 cools down under the action of the refrigerant in the compressor 2 and the circulation pipeline, serving as a cold source for temperature regulation in each storage compartment. The cooling system is used to directly or indirectly deliver the cooling capacity of the evaporator 3 to each storage compartment. Optionally, the cooling system includes a connected evaporator cavity 107, a fan 4, and an air duct. The air duct is used to transport the cooling capacity generated by the evaporator 3 in the evaporator cavity 107 to the cooling points via airflow, and to return the airflow that has completed heat exchange at the cooling points to the evaporator cavity 107. Specifically, an evaporator 3 is provided inside the evaporator cavity 107. After the airflow in the evaporator cavity 107 exchanges heat with the evaporator 3, a cooling airflow is formed. The fan 4 can drive the airflow in the evaporator cavity 107 into the air duct, and then drive the airflow to flow in the air duct. The cooling airflow in the air duct exchanges heat with each storage compartment, reducing the temperature in the storage compartment. After the heat exchange, the airflow enters the air duct and finally enters the evaporator cavity 107, completing the airflow circulation.

[0050] The refrigerator provided in this application embodiment includes at least a freezer compartment 102 and a soft-freeze compartment 103, and may also include a refrigerator compartment 101. The refrigerator compartment 101 has a refrigeration space, which may be equipped with drawers or shelves, and the refrigerator includes a refrigerator door 104 for opening or closing the refrigeration space. The soft-freeze compartment 103 has a soft-freeze space, which may be equipped with drawers or shelves, and the refrigerator has a soft-freeze door 106 for opening or closing the soft-freeze space. The freezer compartment 102 has a freezer space, which may be equipped with drawers or shelves, and the refrigerator has a freezer door 105 for opening or closing the freezer space. The refrigerator compartment 101, the soft-freeze compartment 103, and the freezer compartment 102 are separated by an insulating foam layer.

[0051] The refrigerator includes a refrigeration module and a connecting passage 6. The refrigeration module includes an air-cooling system and a cooling structure disposed in the soft-freezing compartment 103.

[0052] The air-cooling system is configured to control the temperature within the freezer compartment 102 using air cooling. The evaporator chamber 107 is connected to the freezer compartment 102 via a supply air duct, and the freezer compartment 102 is connected to the evaporator chamber 107 via a return air duct. An evaporator 3 is installed within the evaporator chamber 107. The airflow within the evaporator chamber 107 exchanges heat with the evaporator 3 to form a cooling airflow. A fan 4 drives the airflow within the evaporator chamber 107 into the supply air duct, where it flows. The cooling airflow then enters the freezer compartment 102 for heat exchange, lowering the temperature within the freezer compartment 102 to the target temperature. The airflow within the freezer compartment 102 then continues through the outlet air duct and finally returns to the evaporator chamber 107, completing the airflow circulation.

[0053] The air-cooling system also transfers cooling capacity to the cooling-conducting structure, which is configured to control the temperature within the soft-freezing compartment 103 using direct cooling. Specifically, the air-cooling system is configured to cool the cooling-conducting structure. During operation, the airflow in the evaporator cavity 107 exchanges heat with the evaporator 3 to form a cooling airflow. The fan 4 drives the cooling airflow in the evaporator cavity 107 to exchange heat with the cooling-conducting structure, transferring cooling capacity to the cooling-conducting structure. The airflow after heat exchange continues to return to the evaporator cavity 107, completing the airflow circulation. The cooling-conducting structure, having obtained cooling capacity, continues to transfer the cooling capacity to the soft-freezing compartment 103 using direct cooling, thereby achieving the purpose of controlling the temperature within the soft-freezing compartment 103.

[0054] The connecting channel 6 of the refrigerator is located inside the cabinet 1. Specifically, the connecting channel 6 is disposed in the insulation foam layer between the soft-freezing compartment 103 and the freezing compartment 102. The two ends of the connecting channel 6 are respectively connected to the freezing compartment 102 and the soft-freezing compartment 103. A first damper 7 is provided in the connecting channel 6 for controlling the opening and closing of the connecting channel 6. When the first damper 7 is open, the connecting channel 6 is in the open state, and the freezing compartment 102 and the soft-freezing compartment 103 are connected through the connecting channel 6; when the first damper 7 is closed, the connecting channel 6 is in the closed state, and the freezing compartment 102 and the soft-freezing compartment 103 cannot be connected through the connecting channel 6.

[0055] In the above embodiment, when the soft freezer door 106 is closed, the entire soft freezer compartment 103 forms a relatively sealed space. The cooling structure is located inside the soft freezer compartment 103 and exchanges heat with the soft freezer compartment 103 in a direct cooling manner, so that the interior of the soft freezer area and the stored items are reduced to the preset temperature, which can effectively avoid the problem of low humidity and dry loss of items caused by direct cold air blowing.

[0056] In another usage scenario, every time a user opens the soft freezer compartment 103 to store or retrieve items, because the internal temperature of the soft freezer compartment 103 is lower than the outside air temperature, moisture from the outside air will enter the soft freezer compartment 103 and accumulate over time, forming condensation. Since the soft freezer compartment 103 is below zero degrees Celsius, the condensation will cause frost and ice to form inside, similar to a direct-cooling refrigerator. Frost and ice formation will reduce the cooling efficiency of the soft freezer compartment 103, and in severe cases, make the drawers inside the soft freezer compartment difficult to open, causing inconvenience to the user. Furthermore, every time a user opens the soft-freezing compartment 103 to store or retrieve items, external heat enters the soft-freezing compartment 103, causing the temperature inside the soft-freezing compartment 103 to rise. The cooling speed of the direct cooling method using the heat conduction structure is relatively low, which may cause the surface of the stored food to melt and thaw. Repeated temperature fluctuations may also cause recrystallization of the meat, thus reducing the preservation effect of soft freezing on meat. In addition, the direct cooling method using the heat conduction structure cannot reduce the humidity inside.

[0057] In the embodiments described above, a connecting channel 6 is provided between the soft-freezing compartment 103 and the freezing compartment 102. This allows for heat and moisture transfer between the two compartments when the connecting channel 6 is open. By controlling the opening and closing of the connecting channel 6, excess moisture in the soft-freezing compartment 103 is promptly discharged into the freezing compartment 102, and the temperature inside the soft-freezing compartment 103 rapidly decreases due to air convection, thereby reducing the temperature and humidity within the soft-freezing compartment 103. It should be noted that the connecting channel 6 operates when the soft-freezing compartment 103 of the refrigerator is opened, resulting in an increase in both temperature and humidity. The connecting channel 6 facilitates heat and humidity exchange between the soft-freezing compartment 103 and the freezing compartment 102. When the soft-freezing compartment 103 operates smoothly in its normally closed state, its internal humidity does not fluctuate significantly. In this scenario, the cooling structure of the refrigeration module is sufficient to maintain the normal temperature within the soft-freezing area.

[0058] In some embodiments, the soft-freezing compartment 103 is located above the freezing compartment 102, and the connecting channel 6 is used to guide the condensation in the soft-freezing compartment 103 to flow into the freezing compartment 102 by gravity. The freezing compartment 102, which stores frozen food for a long time, is generally frozen at -18°C or lower, and the freezing compartment 102 uses air cooling for temperature control, resulting in low humidity and food dehydration issues within the freezing compartment 102. In this embodiment, each time a user opens the soft-freezing compartment 103 to store or retrieve items, because the internal temperature of the soft-freezing compartment 103 is lower than the external air temperature, moisture from the external air will enter the soft-freezing compartment 103 and accumulate there over a long period of time, producing condensation. The connecting channel 6 guides the condensation in the soft-freezing compartment 103 to flow by gravity into the freezing compartment 102, which can replenish the water in the freezing compartment 102, thereby increasing the humidity of the freezing compartment 102 to a certain extent and reducing the dehydration of the food in the freezing compartment 102.

[0059] In some embodiments, the cooling structure is a soft-freezing air duct 5, within which the cold air generated by the air-cooling system circulates. The soft-freezing air duct 5 extends into the soft-freezing compartment 103. Cold air from the refrigeration system can carry away heat from the soft-freezing compartment 103 by passing through the soft-freezing air duct 5. When the soft-freezing compartment 103 needs cooling, the soft-freezing air duct 5 is opened, the air-cooling system is activated, and the cold air generated by the air-cooling system continuously circulates within the soft-freezing air duct 5. Through heat conduction from the wall of the soft-freezing air duct 5, the interior of the soft-freezing compartment 103 and the stored items are lowered to a preset temperature. This achieves cooling using a non-direct airflow method, reducing the dehydration of meat stored in the soft-freezing compartment 103 and improving the preservation effect of the soft-freezing compartment 103. To facilitate the opening and closing of the soft-freezing air duct 5, a second air damper 8 is provided between the soft-freezing air duct 5 and the air-cooling system. When the second air damper 8 is open, the soft-freezing air duct 5 is connected to the air-cooling system, and the cold air generated by the air-cooling system can enter the soft-freezing air duct 5 for circulation. When the second air damper 8 is closed, the soft-freezing air duct 5 is not connected to the air-cooling system, and the cold air generated by the air-cooling system cannot enter the soft-freezing air duct 5.

[0060] In some embodiments, the shape of the soft-freezing air duct 5 within the soft-freezing chamber 103 includes, but is not limited to, a straight line, a U-shape, and a serpentine shape. Setting the soft-freezing air duct 5 in a U-shape or a serpentine shape can increase the effective length of the soft-freezing air duct 5 within the soft-freezing chamber 103 and increase the heat exchange area. However, the serpentine structure will increase the internal air resistance. To balance the heat exchange area and air resistance, the soft-freezing air duct 5 is arranged in a U-shape within the soft-freezing chamber 103, and the soft-freezing air duct 5 is arranged as close as possible to the wall of the soft-freezing chamber 103 to reduce the space occupied by the soft-freezing air duct 5 within the soft-freezing chamber 103.

[0061] In some embodiments, a first temperature sensor and a humidity sensor are installed in the soft-freezing compartment 103. The first temperature sensor is used to collect the temperature inside the soft-freezing compartment 103 in real time, and the humidity sensor is used to collect the humidity inside the soft-freezing compartment 103 in real time. A second temperature sensor is installed in the freezing compartment 102, and the second temperature sensor is used to collect the temperature inside the freezing compartment 102 in real time. By using the first temperature sensor, the second temperature sensor, and the humidity sensor, the temperature and humidity inside the soft-freezing compartment 103, as well as the temperature inside the freezing compartment 102, can be monitored in real time.

[0062] Based on the same technical concept, this application also provides a method for operating a food preservation refrigerator, which is applied to the food preservation refrigerator in the foregoing embodiments of this application. Figure 2 As shown, the working method of a fresh food refrigerator includes:

[0063] Step 1: After detecting that the soft-freezing compartment has been opened, monitor in real time whether the soft-freezing compartment has been closed;

[0064] Step 2: When the soft-freezing compartment is closed, the temperature inside the soft-freezing compartment is recorded as the first temperature T1, the humidity inside the soft-freezing compartment is recorded as the first humidity H1, and the temperature inside the freezing compartment is recorded as the second temperature t0.

[0065] Step 3: The air-cooling system controls the temperature inside the freezer room to drop from the second temperature t0 to the third temperature T2;

[0066] Step 4: Control the opening and closing of the connecting channel and the soft freezing air duct so that the temperature in the soft freezing room reaches the preset temperature T0 and the humidity in the soft freezing room reaches the preset humidity H0.

[0067] Each time a user opens the soft freezer compartment 103 to store or retrieve items, moisture from the outside air enters the compartment because the internal temperature is lower than the outside air temperature. This moisture accumulates and condenses over time. Furthermore, each time the user opens the soft freezer compartment 103, heat from the outside enters, causing the internal temperature to rise. In the above implementation, step 1 obtains information about the opening and closing of the soft-freezing compartment door, which serves as the trigger condition for starting the operation method of the refrigerator in this application embodiment; in step 2, after the soft-freezing compartment of the refrigerator has experienced this door opening and closing, at the moment the door is closed, the first temperature T1 and the first humidity H1 inside the soft-freezing compartment, and the second temperature t0 inside the freezer compartment are obtained. The first temperature T1 and the first humidity H1 are used to evaluate the deviation of the current temperature and humidity inside the soft-freezing compartment from the preset values, and the second temperature t0 inside the freezer compartment is used to evaluate the potential of the freezer compartment to provide cooling capacity to the soft-freezing compartment, providing basic data for cooling capacity control in subsequent steps; in step 3, each time the user opens the soft-freezing compartment to store or retrieve items, the air-cooling system simultaneously activates when the soft-freezing compartment is closed. The process begins by cooling the freezer compartment, which stores cold energy to ensure that the freezer compartment remains within its normal temperature range after transferring cold energy to the soft-freezing compartment. In step 4, once the freezer compartment has finished cooling, the first damper in the connecting channel opens, allowing cold energy to convect from the freezer compartment to the soft-freezing compartment. Simultaneously, moisture in the soft-freezing area can be drained into the freezer compartment. If the temperature is not up to standard, the soft-freezing air duct can be activated to further cool the soft-freezing compartment until the temperature and humidity levels in the soft-freezing compartment reach the preset values. This achieves rapid cooling and dehumidification of the soft-freezing compartment, improving its preservation effect. It also replenishes water to the freezer compartment to a certain extent, further enhancing its preservation effect.

[0068] It should be noted that this method is based on the refrigerator described in the foregoing embodiments of this application. By setting a connecting channel 6 between the soft-freezing compartment 103 and the freezing compartment 102, heat and moisture can be transferred between the soft-freezing compartment 103 and the freezing compartment 102 when the connecting channel 6 is open. By controlling the opening and closing of the connecting channel 6, excess moisture in the soft-freezing compartment 103 can be discharged into the freezing compartment 102 in a timely manner, and the temperature in the soft-freezing compartment 103 can be rapidly reduced under air convection, thereby achieving the purpose of reducing the temperature and humidity in the soft-freezing compartment 103.

[0069] In the aforementioned embodiment, the working scenario of the refrigerator's operation method is that after the soft-freezing compartment 3 of the refrigerator is opened, both the temperature and humidity inside the soft-freezing compartment increase. Heat and humidity exchange is established between the soft-freezing compartment and the freezer compartment through the connecting channel. Therefore, step 1 is the trigger condition for the operation method of this embodiment. When the soft-freezing compartment is running smoothly in the normally closed state, its internal humidity will not fluctuate significantly. In this scenario, the normal temperature in the soft-freezing area can be maintained by the cooling structure of the refrigeration module, and this operation method is not required.

[0070] In some embodiments, the third temperature T2 ≤ t0 - (T1 - T0). According to the heat transfer formula... Where K represents the thermal conductivity coefficient, A represents the heat transfer area, ΔT represents the temperature difference, and Δd represents the heat transfer distance. Assuming no heat loss during heat transfer, the temperature changes between the soft-freezing and freezing compartments are the same; that is, the temperature change of the soft-freezing compartment is equal to the temperature change of the freezing compartment. In other words, after opening the connecting passage, the temperature of the soft-freezing compartment drops from the first temperature T1 to the preset temperature T0, while the temperature of the freezing compartment simultaneously rises from t0 - (T1 - T0) to the second temperature t0, which is the normal operating temperature of the freezing compartment. At this point, the third temperature T2... = t0-(T1-T0). Since there will be some heat loss during the heat transfer process, in the actual control process, it is advisable to set the third temperature to T2≤t0-(T1-T0). In this way, the freezer compartment can provide enough cooling capacity to the soft freezer compartment so that the temperature in the soft freezer compartment can be raised to the preset temperature T0, and the temperature of the freezer compartment can be maintained at the second temperature t0.

[0071] In some embodiments, the process of controlling the opening and closing of the connecting channel and the soft-freezing air duct to make the temperature in the soft-freezing room reach a preset temperature T0 and the humidity in the soft-freezing room reach a preset humidity H0 includes: controlling the soft-freezing air duct to close and the connecting channel to open, so that both the temperature and humidity in the soft-freezing room decrease; and determining whether to open the soft-freezing air duct based on the priority of the temperature in the soft-freezing room reaching the preset temperature T0 and the humidity in the soft-freezing room reaching the preset humidity H0.

[0072] Because the temperature and humidity inside the soft-freezing compartment vary depending on the external environment after the user opens it, the degree of temperature and humidity change will differ at different times during operation. Furthermore, the temperature and humidity inside the freezer compartment are not constant. Although the freezer compartment maintains a low temperature and low humidity state compared to the soft-freezing compartment, both temperature and humidity will drop rapidly when the connecting aisle is opened. However, which indicator reaches the preset value first varies under different operating conditions, and it is difficult for both to reach the preset value simultaneously. If the first indicator reaches the preset value first, and the connecting aisle remains open to allow the second indicator to drop to its preset value, then after the second indicator reaches its preset value, the first indicator will be lower than its preset value, affecting the control parameters inside the soft-freezing compartment and negatively impacting food preservation. Therefore, after the humidity reaches the preset value first, consider closing the connecting aisle and opening the soft-freezing aisle. Use a soft-freezing air duct that will not affect the humidity inside the soft-freezing compartment to continue lowering the temperature until the temperature also reaches the preset value.

[0073] like Figure 3 As shown, the process of determining whether to open the soft-freezing air duct based on the priority of the temperature in the soft-freezing room reaching a preset temperature T0 and the humidity in the soft-freezing room reaching a preset humidity H0 includes:

[0074] If the temperature inside the soft-freezing room reaches the preset temperature T0 first, the connecting channel is closed. When the temperature inside the soft-freezing room rises back to T0 + ΔT, the connecting channel is reopened. Then, when the temperature inside the soft-freezing room drops back to the preset temperature T0, the connecting channel is closed again. This cycle continues until the humidity inside the soft-freezing room reaches the preset humidity H0, where 0.1℃ ≤ ΔT ≤ 1.5℃. Figure 3 The following explanation uses ΔT = 1℃ as an example. During this process, due to heat loss, the temperature inside the soft-freezing room will continue to rise when the connecting passage is closed. When the temperature rises, the connecting passage will be reopened to lower the temperature and humidity at the same time. This process will be repeated multiple times until both the temperature and humidity reach the preset values.

[0075] If the humidity in the soft-freezing room reaches the preset humidity H0 first, the connecting channel is closed and the soft-freezing air duct is opened. After the temperature in the soft-freezing room reaches the preset temperature T0, the soft-freezing air duct is closed.

[0081] Optionally, the process of determining whether to open the soft-freezing air duct based on the priority of the temperature in the soft-freezing room reaching a preset temperature T0 and the humidity in the soft-freezing room reaching a preset humidity H0 includes: if the temperature in the soft-freezing room reaches the preset temperature T0 first, then the connecting channel is closed; when the temperature in the soft-freezing room rises back to T0+ΔT, the connecting channel is reopened; and when the temperature in the soft-freezing room drops back to the preset temperature T0, the connecting channel is closed again, and so on, until the humidity in the soft-freezing room reaches the preset humidity H0, where 0.1℃≤ΔT≤1.5℃.
