Technical Field

[0002] This application relates to the field of refrigeration equipment, and more particularly to a refrigeration device and its control method. Background Technology

[0003] Modified atmosphere storage (MAP) achieves its preservation purpose by adjusting the proportion of a specific gas (such as oxygen) within the modified atmosphere container. To achieve MAP, refrigeration equipment typically requires the installation of an oxygen control module, which processes the specific gas component to increase or decrease its concentration.

[0175] The present application will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present application, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of this application.

[0176] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0177] In the various figures of this application, for ease of illustration, certain dimensions of structures or parts may be exaggerated relative to other structures or parts; therefore, they are only used to illustrate the basic structure of the subject matter of this application.

[0178] Figures 1 to 21 show schematic diagrams of the refrigeration equipment provided in this application, which includes an oxygen-regulating module 10, a modified atmosphere container 20, and a heat sink 30. The oxygen-regulating module 10 is used to perform an electrochemical reaction and produce modified oxygen gas. The modified atmosphere container 20 is used to adjust the gas concentration within it as needed. The modified atmosphere container 20 is connected to the oxygen-regulating module 10 to receive the modified oxygen gas produced by the module 10 to regulate its oxygen content. The heat sink 30 is used to exchange heat with the oxygen-regulating module 10 to cool it down, thereby preventing the temperature of the oxygen-regulating module 10 from becoming too high and affecting the temperature inside the modified atmosphere container 20. This refrigeration equipment includes, but is not limited to, refrigerators and freezers.

[0179] Specifically, the modified atmosphere container 20 receives oxygen-conditioned gas prepared by the oxygen-conditioning module 10, thereby creating a low-temperature, low-oxygen or low-temperature, high-oxygen environment within the modified atmosphere container 20. The oxygen-conditioning module 10 consumes or increases the oxygen content within the modified atmosphere container 20 through an electrochemical reaction, and utilizes the airflow connection between the modified atmosphere container 20 and the oxygen-conditioning module 10 to adjust (consume or increase) the proportion of oxygen within the modified atmosphere container 20.

[0180] The oxygen regulation module 10 includes an electrolyte storage chamber 13 and an electrode assembly exposed within the electrolyte storage chamber 13. In this embodiment, the electrolyte storage chamber 13 can contain an alkaline electrolyte, such as 0.1–8 mol / L NaOH or KOH, the concentration of which can be adjusted according to actual needs. The electrode assembly is powered by a power source and connected to the positive and negative terminals of the power source. It can consume or increase the oxygen content within the oxygen regulation module 10 through an electrochemical reaction, and adjust (i.e., consume or increase) the proportion of oxygen within the modified atmosphere container 20 by utilizing the airflow communication between the oxygen regulation module 10 and the modified atmosphere container 20.

[0181] The electrode assembly includes a first electrode 11 and a second electrode 12. The first electrode 11 and the second electrode 12 are arranged alternately, located on opposite sides of the electrolyte storage chamber 13. The first electrode 11 and the second electrode 12 are respectively connected to the anode and cathode of the power supply, and after energization, the first electrode 11 and the second electrode 12 respectively generate oxygen-conditioned gas.

[0182] After being energized, oxygen reaches the surface of the first electrode 11 connected to the cathode of the power supply. Under the action of the DC electric field, an oxygen dissolution reaction occurs on the surface of the first electrode 11, and then a reverse reaction occurs on the second electrode 12 connected to the anode of the power supply to produce pure oxygen. By introducing the oxygen-conditioned gas prepared by the oxygen-conditioned module 10 into the modified atmosphere container 20 connected to the oxygen-conditioned module 10, the oxygen content in the modified atmosphere container 20 can be increased or decreased.

[0183] Taking the modified atmosphere container 20 receiving oxygen-modified gas from the first electrode 11 to reduce the oxygen content inside the modified atmosphere container 20 as an example.

[0184] The second electrode 12 is located outside the modified atmosphere container 20. The heat dissipation component 30 includes a first heat dissipation component 31 that is attached to the second electrode 12 and exchanges heat with the second electrode 12. The first heat dissipation component 31 reduces the temperature of the second electrode 12, and the second electrode 12 drives the temperature of the electrolyte in the electrolyte storage cavity 13 to decrease, thereby reducing the temperature of the oxygen regulation module 10 and thus reducing the influence of the oxygen regulation module 10 on the temperature inside the modified atmosphere container 20.

[0185] Of course, the modified atmosphere container 20 can also receive oxygen-modified gas from the second electrode 12 to increase the oxygen content inside the modified atmosphere container 20. In this case, the first electrode 11 is located outside the modified atmosphere container 20, and the first heat sink 31 is attached to the first electrode 11. The temperature of the first electrode 11 is reduced by the first heat sink 31, which in turn lowers the temperature of the electrolyte in the electrolyte storage chamber 13, thereby reducing the temperature of the oxygen regulation module 10 and thus reducing the influence of the oxygen regulation module 10 on the temperature inside the modified atmosphere container 20.

[0186] Heat is dissipated by the first electrode 11 or the second electrode 12 located outside the modified atmosphere container 20, and the heat is transferred to the outside of the modified atmosphere container 20 through the first heat dissipation component 31, thereby effectively reducing the temperature of the oxygen regulation module 10, and thus reducing the impact of the heat generated by the operation of the oxygen regulation module 10 on the temperature inside the modified atmosphere container 20.

[0187] Referring to Figures 1 to 3, in one embodiment, the first electrode 11 is located inside the modified atmosphere container 20. Oxygen within the modified atmosphere container 20 participates in a reduction reaction at the location of the first electrode 11, thereby gradually consuming the oxygen within the modified atmosphere container 20. Meanwhile, an oxidation reaction occurs at the second electrode 12, located outside the modified atmosphere container 20, generating oxygen.

[0188] During the electrochemical reaction in the oxygen regulation module 10, the temperature of the electrolyte in the electrolyte storage chamber 13 gradually increases, which in turn raises the temperature of the entire oxygen regulation module 10. This heat is then transferred from the first electrode 11 to the modified atmosphere container 20, causing the temperature of the modified atmosphere container 20 to rise. However, by providing a first heat sink 31 to the second electrode 12, the heat from the electrolyte in the electrolyte storage chamber 13 is transferred from the second electrode 12 to the outside of the modified atmosphere container 20 through the first heat sink 31, effectively reducing the temperature of the oxygen regulation module 10 and preventing large temperature fluctuations within the modified atmosphere container 20 during the oxygen regulation process.

[0189] In one specific embodiment, the first heat sink 31 is a heat sink attached to the second electrode 12. The second electrode 12 transfers heat to the heat sink, which increases the heat exchange area between the second electrode 12 and the external air of the modified atmosphere container 20, thereby accelerating the reduction of the temperature of the oxygen regulation module 10 and reducing the impact of the oxygen regulation module 10 on the temperature inside the modified atmosphere container 20.

[0190] The heat sink can also be paired with a cooling fan to accelerate airflow at the heat sink, thereby further improving the heat dissipation efficiency of the heat sink.

[0191] In this embodiment, the connection method of the heat sink and the second electrode 12 is not specifically limited. The two can be directly connected or indirectly connected, as long as the second electrode 12 can transfer heat to the heat sink.

[0192] In another specific embodiment, the first heat sink 31 is a semiconductor cooling element coupled with a cooling fan. The semiconductor cooling element includes a cold end and a hot end. The cold end of the semiconductor cooling element is in contact with the second electrode 12, and the hot end of the semiconductor cooling element is equipped with a cooling fan. The semiconductor cooling element transfers cooling energy to the second electrode 12 through the cold end to cool the second electrode 12, thereby reducing the temperature of the oxygen regulation module 10.

[0193] Referring to FIG4, in another embodiment, the refrigeration device further includes a communication cavity 40 for connecting the oxygen regulation module 10 and the modified atmosphere container 20, wherein the first electrode 11 is located in the communication cavity 40.

[0194] An opening is provided on the side of the connecting cavity 40 away from the first electrode 11, and the connecting cavity 40 is connected to the modified atmosphere container 20 through the opening. Air flows between the modified atmosphere container 20 and the connecting cavity 40. Oxygen in the air in the connecting cavity 40 participates in a reduction reaction at the position of the first electrode 11, thereby gradually consuming the oxygen in the modified atmosphere container 20 and the connecting cavity 40. Meanwhile, an oxidation reaction occurs at the second electrode 12 located outside the modified atmosphere container 20, generating oxygen.

[0195] Similar to the previous embodiment, during the electrochemical reaction in the oxygen regulation module 10, the temperature of the electrolyte in the electrolyte storage chamber 13 gradually increases, thereby raising the temperature of the entire oxygen regulation module 10. By providing a first heat sink 31 on the second electrode 12, the temperature of the oxygen regulation module 10 is effectively reduced, preventing large temperature fluctuations within the modified atmosphere container 20 during oxygen regulation. The first heat sink 31 can be a heat sink or a semiconductor cooling component, coupled with a cooling fan.

[0196] In this embodiment, the connecting cavity 40 can also be cooled. It is understood that since the first electrode 11 is located inside the connecting cavity 40, some of the heat from the electrolyte will be transferred from the first electrode 11 to the connecting cavity 40. By cooling the connecting cavity 40, the temperature of the oxygen-conditioned gas inside the connecting cavity 40 is reduced, preventing the oxygen-conditioned gas from flowing into the modified atmosphere container 20 and affecting the temperature inside the modified atmosphere container 20. The first heat sink 31 can also be used to cool the connecting cavity 40.

[0197] Referring to Figures 5 and 6, based on the embodiment shown in Figure 4, the connecting cavity 40 includes an inlet pipe 41 and an outlet pipe 42 that communicate with the modified atmosphere container 20. Air from the modified atmosphere container 20 flows into the connecting cavity 40 through the inlet pipe 41. Oxygen in the air flowing into the connecting cavity 40 participates in a reduction reaction at the position of the first electrode 11, thereby reducing the oxygen content in the connecting cavity 40. The low-oxygen air from the connecting cavity 40 then flows into the modified atmosphere container 20 through the outlet pipe 42, thereby reducing the oxygen content in the modified atmosphere container 20.

[0198] A flow guide 50 is provided in the modified atmosphere container 20 and / or the connecting cavity 40. The flow guide 50 drives the oxygen-controlled gas in the connecting cavity 40 to be transported from the outlet pipe 42 into the modified atmosphere container 20. The flow guide 50 accelerates the airflow between the modified atmosphere container 20 and the connecting cavity 40, thereby accelerating the regulation of the oxygen content in the modified atmosphere container 20.

[0199] In this embodiment, the flow guide 50 is disposed within the connecting cavity 40 and directly opposite the outlet pipe 42 to guide the oxygen-conditioned gas within the connecting cavity 40 into the modified atmosphere container 20. The flow guide 50 is a flow guide fan.

[0200] In some embodiments, the refrigeration device further includes a cooling element 60 for dissipating heat from the inlet pipe 41 and / or the outlet pipe 42. The cooling element 60 dissipates heat from the inlet pipe 41 and / or the outlet pipe 42, thereby reducing the temperature of the air within the inlet pipe 41 and / or the outlet pipe 42, and consequently reducing the impact of gas circulation between the controlled atmosphere container 20 and the connecting cavity 40 on the temperature within the controlled atmosphere container 20. The cooling element 60 may be configured with reference to the first heat dissipation element 31; alternatively, a fan may be used to dissipate heat from the inlet pipe 41 and / or the outlet pipe 42.

[0201] The oxygen control module 10 also includes a circulation pipe 14, both ends of which are connected to the electrolyte storage chamber 13 to achieve electrolyte circulation between the electrolyte storage chamber 13 and the circulation pipe 14. The heat dissipation component 30 includes a second heat dissipation component 32 attached to the outer wall of the circulation pipe 14. The second heat dissipation component 32 cools the electrolyte in the circulation pipe 14, and the electrolyte in the circulation pipe 14 flows into the electrolyte storage chamber 13, thereby reducing the temperature of the oxygen control module 10 and thus reducing the impact of the oxygen control module 10 on the temperature of the modified atmosphere container 20.

[0202] The electrolyte storage chamber 13 includes a first connection port 131 and a second connection port 132. The two ends of the circulation pipe 14 are connected to the first connection port 131 and the second connection port 132, respectively. The electrolyte in the electrolyte storage chamber 13 flows into the circulation pipe 14 from the second connection port 132 and flows through the second heat sink 32 for cooling. Then it flows back into the electrolyte storage chamber 13 from the first connection port 131, thereby achieving circulating cooling of the electrolyte and reducing the impact of the heat generated by the oxygen regulation module 10 on the modified atmosphere container 20.

[0203] Preferably, the first connection port 131 and the second connection port 132 are spaced apart along the height direction of the electrolyte storage cavity 13, thereby increasing the flow area of ​​the electrolyte in the electrolyte storage cavity 13 and improving the circulating cooling effect of the electrolyte.

[0204] Referring to Figures 7 to 11, in one embodiment, the electrolyte circulation in the oxygenation module 10 and the circulation pipeline 14 is achieved through the temperature difference of the electrolyte.

[0205] The height of the highest point of the circulation pipeline 14 is less than or equal to the liquid level in the electrolyte storage chamber 13, thereby ensuring that the circulation pipeline 14 is filled with electrolyte and that the electrolyte can circulate between the oxygen regulation module 10 and the circulation pipeline 14.

[0206] The second heat sink 32 is located in the heat dissipation section 141 of the circulation pipe 14. The heat dissipation section 141 has a liquid outlet 141a and a liquid inlet 141b located above the liquid outlet 141a. It can be understood that the highest point of the second heat sink 32 in the circulation pipe 14 is the liquid inlet 141b, and the lowest point of the second heat sink 32 in the circulation pipe 14 is the liquid outlet 141a.

[0207] The liquid outlet 141a is connected to the first connection port 131, and the liquid outlet 141a is located above the first connection port 131, that is, the heights of the liquid inlet 141b, the liquid outlet 141a, and the first connection port 131 gradually decrease. The liquid inlet 141b is connected to the second connection port 132.

[0208] When the oxygen control module 10 is working, the temperature of the electrolyte in the electrolyte storage chamber 13 rises, resulting in a decrease in electrolyte density. Meanwhile, the electrolyte in the heat dissipation section 141 has a lower temperature and higher density. Due to the height difference between the inlet 141b and the outlet 141a, and between the outlet 141a and the first connection port 131, the lower-temperature, higher-density electrolyte in the heat dissipation section 141 flows downwards from the first connection port 131 into the electrolyte storage chamber 13. The electrolyte in the electrolyte storage chamber 13 then gradually flows into the heat dissipation section 141 from the second connection port 132, thus completing a cycle to reduce the electrolyte temperature and decrease the impact of the oxygen control module 10's heat generation on the modified atmosphere container 20.

[0209] The circulation pipeline 14 includes a first section 142 connected to the first connection port 131, a second section 143 connected to the second connection port 132, and a third section 144 connecting the first section 142 and the second section 143.

[0210] Referring to Figures 7 to 9, the second connection port 132 is located above the first connection port 131, and the highest point of the circulation pipe 14 is flush with the second connection port 132.

[0211] Referring to Figures 7 and 8, in a specific embodiment, the first segment 142 and the second segment 143 extend horizontally, and the third segment 144 extends vertically. The second heat sink 32 is located in the third segment 144, that is, the heat sink segment 141 is located in the third segment 144, and both the liquid outlet 141a and the liquid inlet 141b are located in the third segment 144.

[0212] In this embodiment, the second connection port 132 is located above the liquid inlet 141b. The heights of the second connection port 132, the liquid inlet 141b, the liquid outlet 141a, and the first connection port 131 gradually decrease. The second connection port 132 is connected to the liquid inlet 141b via the second segment 143, and the first connection port 131 is connected to the liquid outlet 141a via the first segment 142.

[0213] The electrolyte with low temperature and high density in the heat dissipation section 141 flows into the electrolyte storage chamber 13 through the first connection port 131 via the first section 142. The electrolyte in the electrolyte storage chamber 13 flows into the heat dissipation section 141 through the liquid inlet 141b via the second section 143, so as to achieve the circulation and cooling of the electrolyte.

[0214] Referring to Figure 9, in another embodiment, the only difference from the embodiment shown in Figure 8 is that the second heat sink 32 is located in the second segment 143 and the third segment 144. That is, the heat sink segment 141 is located in the second segment 143 and the third segment 144, the liquid inlet 141b is located in the second segment 143, and the liquid outlet 141a is located in the third segment 144.

[0215] In this embodiment, the second connection port 132 and the liquid inlet 141b are flush. The electrolyte with low temperature and high density in the heat dissipation section 141 flows into the electrolyte storage chamber 13 through the first connection port 131 via the first section 142. The electrolyte in the electrolyte storage chamber 13 flows into the heat dissipation section 141 through the liquid inlet 141b, so as to achieve the circulation and cooling of the electrolyte.

[0216] Referring to Figures 10 and 11, the height of the highest point of the circulation pipe 14 is greater than the height of the first connection port 131 and the second connection port 132.

[0217] The first segment 142 and the second segment 143 extend horizontally, and the third segment 144 is a U-shaped pipe segment. The highest point of the U-shaped pipe segment is greater than the height of the first connection port 131 and the second connection port 132. The U-shaped pipe segment includes a first vertical segment connected to the first segment 142, a second vertical segment connected to the second segment 143, and a third horizontal segment connecting the first vertical segment and the second vertical segment.

[0218] Referring to FIG10, in a specific embodiment, the first connection port 131 is located below the second connection port 132, and the electrolyte in the circulation pipeline 14 flows in a clockwise direction.

[0219] The electrolyte with low temperature and high density in the heat dissipation section 141 flows into the electrolyte storage chamber 13 through the first connection port 131 via the first section 142. The electrolyte in the electrolyte storage chamber 13 flows into the heat dissipation section 141 through the liquid inlet 141b, so as to achieve the circulation and cooling of the electrolyte.

[0220] Referring to Figure 11, in another embodiment, the only difference from the embodiment shown in Figure 10 is that the first connection port 131 is located above the second connection port 132, and the electrolyte in the circulation pipeline 14 flows in a counterclockwise direction.

[0221] The electrolyte with low temperature and high density in the heat dissipation section 141 flows into the electrolyte storage chamber 13 through the first connection port 131 via the first section 142. The electrolyte in the electrolyte storage chamber 13 flows into the heat dissipation section 141 through the liquid inlet 141b, so as to achieve the circulation and cooling of the electrolyte.

[0222] Referring to Figures 12 to 14, in another embodiment, the electrolyte circulation in the oxygenation module 10 and the circulation pipeline 14 is achieved by a drive unit 145.

[0223] The second heat sink 32 in the circulation pipe 14 is located at the heat dissipation section 141. A drive unit 145 is installed on the circulation pipe 14 to drive the electrolyte flow. Under the action of the drive unit 145, the electrolyte with a lower temperature in the heat dissipation section 141 flows from the first connection port 131 into the electrolyte storage chamber 13, and the electrolyte in the electrolyte storage chamber 13 flows from the second connection port 132 into the heat dissipation section 141 for cooling. This completes the circulation, achieving the effect of lowering the electrolyte temperature and reducing the impact of the oxygen regulation module 10's heat generation on the modified atmosphere container 20. The drive unit 145 can be a drive pump.

[0224] To ensure that the drive unit 145 can properly drive the electrolyte to flow between the heat dissipation section 141 and the circulation pipe 14, the height of at least one of the first connection port 131 and the second connection port 132 is less than or equal to the liquid level in the electrolyte storage chamber 13. In this way, the drive unit 145 can draw electrolyte from the connection port below the liquid level and allow it to flow through the heat dissipation section 141.

[0225] Compared to the solution that achieves electrolyte self-circulation through temperature difference, the solution that drives electrolyte flow through drive component 145 does not require consideration of the position of the second heat sink 32, meaning the heat sink section 141 can be located anywhere in the circulation pipeline 14. There is no need to ensure a height difference between the inlet 141b, the outlet 141a, and the first connection port 131.

[0226] Referring to Figure 12, in a specific embodiment, the heights of both the first connection port 131 and the second connection port 132 are lower than the electrolyte level in the electrolyte storage chamber 13, ensuring that the circulation pipeline 14 is always filled with electrolyte. Under the action of the driving component 145, the electrolyte circulates between the electrolyte storage chamber 13 and the heat dissipation section 141 to reduce the electrolyte temperature.

[0227] Referring to Figure 13, in another embodiment, the only difference from the embodiment shown in Figure 12 is that the first connection port 131 is located below the second connection port 132 and below the liquid level in the electrolyte storage chamber 13. The second connection port 132 is above the liquid level in the electrolyte storage chamber 13.

[0228] When the drive unit 145 is turned on, electrolyte is drawn from the electrolyte storage chamber 13 through the first connection port 131 and injected into the circulation pipeline 14 and flows through the heat dissipation section 141 for cooling. The cooled electrolyte then flows back into the electrolyte storage chamber 13 through the second connection port 132, thereby completing the circulation and achieving the effect of reducing the electrolyte temperature, thus reducing the impact of the oxygen regulation module 10's heat generation on the modified atmosphere container 20.

[0229] Referring to Figure 13, in another embodiment, the only difference from the embodiment shown in Figure 12 is that the position of the second heat sink 32 is different, that is, the position of the heat dissipation section 141 is different. As before, the scheme of driving the electrolyte flow by the driving member 145 does not need to consider the position of the second heat sink 32, that is, the heat dissipation section 141 can be located at any position in the circulation pipeline 14.

[0230] In this embodiment, the second heat sink 32 is located in the horizontal section. It can be understood that at this time, the liquid inlet 141b, the liquid outlet 141a and the first connection port 131 are all at the same height.

[0231] The circulation pipeline 14 is provided with multiple sets of second heat dissipation components 32 at intervals, that is, it has multiple sets of heat dissipation sections 141, thereby improving the cooling efficiency of the electrolyte.

[0232] It should be noted that the self-circulation schemes shown in Figures 7 to 11 can also have a drive element 145 installed on the circulation pipeline 14 to assist in driving the electrolyte circulation.

[0233] Referring to Figure 15, the oxygen control module 10 is equipped with multiple sets of circulation pipes 14, each of which is provided with a second heat sink 32, thereby improving the cooling efficiency of the electrolyte. In this embodiment, two sets of circulation pipes 14 are provided, which may be identical or different. The arrangement of the circulation pipes 14 and the second heat sink 32 can be selected from any of the above-described options.

[0234] The second heat sink 32 is one or a combination of a heat sink, a semiconductor cooling element, or a combination thereof. The electrolyte in the heat dissipation section 141 can be cooled by the heat sink alone or by a heat sink plus a cooling fan. Alternatively, a semiconductor cooling element can be used in conjunction with a cooling fan, with the cold end of the semiconductor cooling element in contact with the circulation pipe 14, and a cooling fan installed at the hot end of the semiconductor cooling element.

[0235] Referring to Figure 16, the refrigeration equipment also includes a refrigeration chamber 70, within which the controlled atmosphere container 20 is located. The refrigeration equipment further includes a refrigeration system and a cooling air supply path. The cooling air supply path is connected to the refrigeration system and supplies cold air to the area containing the controlled atmosphere container 20, thereby cooling the container 20. The cooling air supply path is equipped with a fan and a damper. When the damper is open, cold air from the cooling air supply path flows into the area containing the controlled atmosphere container 20 under the action of the fan. When the damper is closed, the supply of cold air from the cooling air supply path ceases to the area containing the controlled atmosphere container 20. Simultaneously, the cooling air supply path also supplies cold air into the refrigeration chamber 70 to cool it. The refrigeration system includes a compressor, a condenser, a throttling device, and an evaporator connected in sequence.

[0236] The modified atmosphere container 20 includes a sealed container 21 and a drawer 22 located inside the sealed container 21. A cold air passage is formed between the sealed container 21 and the inner wall of the refrigeration chamber 70. Cold air flows through the cold air passage to cool the environment around the drawer 22, thereby lowering the temperature inside the drawer 22. The drawer 22 is connected to the oxygen conditioning module 10 to receive the oxygen-conditioned gas prepared by the oxygen conditioning module 10.

[0237] The cold air duct has an air inlet and an air return outlet connected to the cooling air supply circuit, thus forming a circulation channel. The damper is used to open or close the air inlet. When the damper is open, the cold air in the cooling air supply circuit enters the cold air duct from the air inlet, thereby reducing the temperature inside drawer 22. The cooled air, after heat exchange, then re-enters the cooling air supply circuit from the air return outlet.

[0238] Of course, the controlled atmosphere container 20 also obtains cooling capacity through heat exchange with the cooling chamber 70. For example, when the cold air in the cooling chamber 70 circulates, it transfers cooling capacity to the controlled atmosphere container 20. The cooling chamber 70 and the controlled atmosphere container 20 can be sealed to each other, or there can be a certain airflow connection between them. Alternatively, the refrigeration system can equip the controlled atmosphere container 20 with a separate evaporator for cooling.

[0239] To improve the accuracy of the oxygen regulating module 10 in adjusting the concentration of a specific gas in drawer 22, a gas concentration sensor (e.g., an oxygen concentration sensor) can be installed in drawer 22 to detect the concentration of oxygen in drawer 22.

[0240] A first temperature sensor is installed on the oxygen conditioning module 10 to detect its temperature. A second temperature sensor is installed inside the modified atmosphere container 20 to detect its internal temperature. Since the oxygen conditioning module 10 generates a large amount of heat during operation, which can affect the temperature inside the modified atmosphere container 20, the operating state of the oxygen conditioning module 10 is adjusted by detecting the temperatures of both the oxygen conditioning module 10 and the modified atmosphere container 20, thereby reducing the impact of the oxygen conditioning module 10 on the temperature inside the modified atmosphere container 20.

[0241] The refrigeration equipment also includes a control device 80 and a current detection device 90. The current detection device 90 detects the real-time current in the circuit and transmits it to the control device 80. The control device 80 controls the opening and closing of the oxygen regulating module 10, and simultaneously controls the operating rate or power of the oxygen regulating module 10. The control device 80 also adjusts the current voltage of the oxygen regulating module 10 based on the real-time current. The control device 80 also controls the opening and closing of the fan, and simultaneously controls the fan speed.

[0242] This application also provides a control method for a refrigeration device, which includes the following steps:

[0243] Start the oxygen regulation module 10 to prepare oxygen-regulated gas;

[0244] The oxygen-controlled gas is delivered to the modified atmosphere container 20, which is connected to the oxygen-controlled module 10.

[0245] When it is necessary to adjust the oxygen content in the modified atmosphere container 20, the oxygen conditioning module 10 is activated to prepare oxygen-conditioned gas and deliver the oxygen-conditioned gas to the modified atmosphere container 20, which is connected to the oxygen conditioning module 10. Specifically, it can be determined whether the oxygen conditioning module 10 needs to be activated by monitoring the oxygen content in the modified atmosphere container 20; or the oxygen conditioning module 10 can be activated periodically.

[0246] Preferably, the oxygen adjustment module 10 is turned on to perform oxygen adjustment after the refrigeration equipment has finished cooling. On the one hand, the temperature inside the modified atmosphere container 20 is at its lowest at this time; on the other hand, the operation of the oxygen adjustment module 10 can avoid the impact of the operation of the modified atmosphere container 20 on the refrigeration of the modified atmosphere container 20.

[0247] Since the oxygen conditioning module 10 generates a lot of heat during operation, it will affect the temperature inside the modified atmosphere container 20. In order to reduce the impact of the oxygen conditioning module 10 on the temperature inside the modified atmosphere container 20 and prevent the temperature inside the modified atmosphere container 20 from becoming too high.

[0248] In some embodiments, the control method further includes:

[0249] The temperature inside the modified atmosphere container 20 is obtained, and it is determined whether the temperature inside the modified atmosphere container 20 has reached the first node temperature. If so, the oxygen regulation module 10 is turned off to cool down the modified atmosphere container 20. After cooling down, the oxygen regulation module 10 is restarted. If not, the oxygen regulation module 10 continues to provide oxygen gas to the modified atmosphere container 20.

[0250] As the oxygen conditioning module 10 operates, its temperature gradually increases, dissipating heat into the modified atmosphere container 20 connected to it, thus raising the temperature within the container. When the temperature inside the container 20 reaches the first node temperature, the oxygen conditioning module 10 is shut down, stopping the oxygen conditioning operation. Simultaneously, the modified atmosphere container 20 is cooled down. After cooling, the oxygen conditioning module 10 is restarted to continue the oxygen conditioning operation.

[0251] The following steps are included before “Restarting Oxygen Module 10”:

[0252] Obtain the temperature and cooling time inside the modified atmosphere container 20;

[0253] Determine if the temperature of the modified atmosphere container 20 is lower than the temperature of the second node. If yes, restart the oxygen control module 10; otherwise, continue to cool down the modified atmosphere container 20.

[0254] And / or, determine whether the cooling time has reached the first threshold. If yes, restart the oxygen regulation module 10; if no, continue cooling the modified atmosphere container 20.

[0255] During the cooling process of the modified atmosphere container 20, the temperature inside the modified atmosphere container 20 is acquired and the cooling time of the modified atmosphere container 20 is recorded. When the temperature inside the modified atmosphere container 20 is lower than the second node temperature and / or the cooling time exceeds the first threshold, the cooling of the modified atmosphere container 20 ends, and the oxygen regulation module 10 can be restarted to continue the oxygen regulation operation.

[0256] The temperature of the second node is lower than that of the first node. The specific temperature settings of the first and second nodes can be adapted to the food stored in the modified atmosphere container 20 or the set storage temperature of the modified atmosphere container 20.

[0257] Cooling the modified atmosphere container 20 includes the following steps:

[0258] Determine whether the temperature inside the refrigeration chamber 70 where the controlled atmosphere container 20 is located has reached the third node temperature.

[0259] If so, the refrigeration equipment will operate in the first refrigeration mode;

[0260] If not, the refrigeration equipment operates in the second refrigeration mode.

[0261] The third node temperature is the start-up setting temperature of the refrigeration system.

[0262] When the temperature inside the cooling chamber 70 reaches the third node temperature, the cooling system needs to be turned on to cool the cooling chamber 70. At the same time, it can also cool the modified atmosphere container 20 inside the cooling chamber 70. That is, in the first cooling mode, the cooling system is run to cool the modified atmosphere container 20.

[0263] When the temperature inside the cooling chamber 70 is lower than the third node temperature, the refrigeration system's start-up set temperature has not been reached, and the refrigeration system does not start. In the second refrigeration mode, the residual cold of the refrigeration system is used to cool the surrounding environment of the controlled atmosphere container. It should be noted that the evaporator can be a cold storage evaporator. In this way, during the operation of the refrigeration system, part of the evaporator can store some cold energy. Thus, when the refrigeration equipment operates in the second refrigeration mode, the cold energy stored in the evaporator can be used to cool the controlled atmosphere container 20.

[0264] In the first cooling mode, the compressor of the refrigeration system is turned on, and the fan and blower in the cooling air supply circuit are turned on. The gas in the cooling air supply circuit flows through the evaporator and exchanges heat with the evaporator to form cold air. The cold air in the cooling air supply circuit enters the cold air channel through the air inlet, and uses the cold air to cool the controlled atmosphere container 20, thereby reducing the temperature inside the controlled atmosphere container 20.

[0265] It should be noted that the refrigeration compartment 70 is also equipped with other air inlets. Specifically, a portion of the cold air from the cooling air supply line enters the cold air duct through the air inlet to cool the controlled atmosphere container 20. A portion of the cold air from the cooling air supply line enters the refrigeration compartment 70 directly through other air inlets or enters other storage spaces within the refrigeration compartment 70.

[0266] When the temperature inside the controlled atmosphere container 20 is lower than the second node temperature, the damper is closed, i.e., the supply of cold air into the cold air duct to cool the controlled atmosphere container 20 is stopped. At the same time, the oxygen regulation module 10 is restarted to continue the oxygen regulation operation.

[0267] When the temperature inside the refrigeration chamber 70 is lower than the fourth node temperature, the refrigeration system and fan are shut down. The fourth node temperature is the shutdown set temperature of the refrigeration system. When the temperature inside the refrigeration chamber 70 is lower than the fourth node temperature, the refrigeration system is shut down. In this embodiment, the second node temperature is higher than the fourth node temperature, meaning the damper closes first, followed by the refrigeration system and fan.

[0268] In the second refrigeration mode, the residual cooling of the refrigeration system is used to cool the surrounding environment of the controlled atmosphere container 20. At this time, the compressor of the refrigeration system is not turned on, and the fan and damper in the cooling air supply circuit are open. In this embodiment, the residual cooling of the refrigeration system is the cold energy stored in the cold storage evaporator.

[0269] When the gas in the cooling air supply line flows through the evaporator, it utilizes the evaporator's cold storage and heat exchange to cool down and form cold air. The cold air in the cooling air supply line enters the cold air channel from the air inlet and uses the cold air to cool down the controlled atmosphere container 20, thereby reducing the temperature inside the controlled atmosphere container 20.

[0270] In one scenario, when the temperature inside the controlled atmosphere container 20 is lower than the second node temperature, the damper and fan are closed, i.e., the supply of cold air into the cold air duct to cool the controlled atmosphere container 20 is stopped. At the same time, the oxygen regulation module 10 is restarted to continue the oxygen regulation operation.

[0271] In another scenario, considering the limited residual cooling of the evaporator, it may not be sufficient to lower the temperature inside the controlled atmosphere container 20 to the second node temperature. In this case, when the cooling duration exceeds the first threshold, the damper and fan are shut off, i.e., the supply of cold air into the cold air duct to cool the controlled atmosphere container 20 is stopped. At the same time, the oxygen regulation module 10 is restarted to continue the oxygen regulation operation.

[0272] Preferably, dampers are also installed at other air inlets of the refrigeration chamber 70. In this way, when the refrigeration equipment switches to the second refrigeration state and uses the residual coolness of the evaporator to cool the controlled atmosphere container 20, the dampers at other air inlets are closed, so that all the cold air in the cooling air supply path enters the cold air channel from the air inlet of the cold air channel to cool the controlled atmosphere container 20, thereby maximizing the reduction of the temperature inside the controlled atmosphere container 20.

[0273] The control method also includes determining whether the cumulative working time of the oxygen conditioning module 10 exceeds a second threshold. If so, the oxygen conditioning module 10 is turned off; otherwise, the oxygen conditioning module 10 continues to supply oxygenated gas to the modified atmosphere container 20.

[0274] Understandably, during the process of adjusting the oxygen content within the modified atmosphere container 20 via the oxygen regulation module 10, the module is intermittently activated to perform oxygen regulation based on the temperature inside the container 20. This prevents the module from operating for extended periods, which could lead to excessively high temperatures within the container and negatively impact the food stored inside. When the cumulative operating time of the oxygen regulation module 10 exceeds a second threshold, the module is deactivated, thus completing the oxygen regulation operation.

[0275] The second threshold can be set based on the oxygen regulation efficiency of the oxygen regulation module 10, the required oxygen content in the modified atmosphere container 20, and the volume adaptability of the modified atmosphere container 20. Preferably, the cumulative working time of the oxygen regulation module 10 is reset after each oxygen regulation operation.

[0276] In other embodiments, the control method further includes:

[0277] Obtain the temperature of the modified atmosphere container 20;

[0278] Calculate the temperature change of the modified atmosphere container 20 within a first preset time period;

[0279] Obtain the module temperature of oxygen control module 10;

[0280] Calculate the temperature change of the oxygen regulation module 10 within a second preset time period;

[0281] The operating rate or power of the oxygen control module 10 is adjusted based on at least one of the controlled atmosphere container temperature, controlled atmosphere container temperature change, module temperature, and module temperature change, so that the controlled atmosphere container temperature does not exceed the threshold temperature.

[0282] The module temperature is detected by a first temperature sensor. The first temperature sensor can be located inside the electrolyte storage chamber 103, or on the first electrode 101 or the second electrode 102. The temperature change of the oxygen-regulating module 10 within a second preset time period is calculated, i.e., the heating rate of the oxygen-regulating module 10 is calculated. The temperature of the modified atmosphere container 20 is detected by a second temperature sensor, and the temperature change of the modified atmosphere container 20 within a first preset time period is calculated, i.e., the heating rate of the modified atmosphere container 20 is calculated.

[0283] The operating rate or power of the oxygen conditioning module 10 is adjusted based on at least one of the following: the temperature of the modified atmosphere container, the temperature change of the modified atmosphere container, the module temperature, and the temperature change of the module, thereby preventing the oxygen conditioning module 10 from generating a large amount of heat during operation and diffusing it into the modified atmosphere container 20, causing the temperature inside the modified atmosphere container 20 to be too high.

[0284] Specifically, the operating rate or power of the oxygen conditioning module 10 can be adjusted based on one of the following: the temperature of the modified atmosphere container, the temperature change of the modified atmosphere container, the module temperature, and the temperature change of the module. Of course, the operating rate or power of the oxygen conditioning module 10 can also be adjusted based on multiple of the following: the temperature of the modified atmosphere container, the temperature change of the modified atmosphere container, the module temperature, and the temperature change of the module.

[0285] It should be noted that, in order to prevent the temperature of the modified atmosphere container from becoming too high, the operating rate or power of the oxygen conditioning module 10 should be adjusted based on the temperature of the modified atmosphere container first; then the temperature change of the modified atmosphere container; next, the module temperature; and finally, the module temperature change. Of course, in order to improve the oxygen production efficiency of the oxygen conditioning module 10, the operating rate or power of the oxygen conditioning module 10 can also be adjusted based on the module temperature first.

[0286] The following provides a detailed explanation of how the operating rate or power of the oxygen regulation module 10 is adjusted based on at least one of the following: controlled atmosphere container temperature, controlled atmosphere container temperature change, module temperature, and module temperature change.

[0287] Referring to Figure 23, in one embodiment, controlling the operating rate of the oxygen conditioning module 10 based on the temperature of the controlled atmosphere container includes the following steps:

[0288] S1. After the oxygen conditioning module 10 is started, when the temperature of the controlled atmosphere container rises to the first preset value T, the oxygen conditioning module 10 is turned off and the process jumps to S2.

[0289] S2. When the temperature of the controlled atmosphere container drops to the second preset value T, the oxygen control module 10 is activated and jumps to S1.

[0290] In this embodiment, the oxygen conditioning module 10 can be activated when the modified atmosphere container 20 starts cooling. In the initial stage of operation, the temperature of the oxygen conditioning module 10 is low, and the heat generated is less than the cooling capacity of the modified atmosphere container 20. At this time, the temperature of the modified atmosphere container will gradually decrease.

[0291] As the oxygen control module 10 continues to work, its temperature gradually increases. When the heat it generates exceeds the cooling capacity of the controlled atmosphere container 20, the temperature of the controlled atmosphere container will gradually increase.

[0292] When the temperature of the modified atmosphere container rises to the first preset value T, the oxygen control module 10 is shut down. This prevents the oxygen control module 10 from continuing to operate and causing the temperature of the modified atmosphere container to rise continuously, which could affect the food stored in the modified atmosphere container 20.

[0293] As the oxygen control module 10 is shut down, the temperature of the modified atmosphere container begins to gradually decrease, and the temperature of the oxygen control module 10 also decreases to some extent. When the temperature of the modified atmosphere container drops by a second preset value T, the oxygen control module 10 is activated and continues to work to regulate the oxygen content in the modified atmosphere container 20. As the oxygen control module 10 continues to work, the temperature of the modified atmosphere container gradually increases. When the temperature of the modified atmosphere container rises by a first preset value T, the oxygen control module 10 is shut down again.

[0294] This process is repeated to control the opening or closing of the oxygen conditioning module 10 by adjusting the temperature of the modified atmosphere container, thereby preventing the oxygen conditioning module 10 from working continuously for a long time and causing the temperature of the modified atmosphere container to rise continuously, thus reducing the impact of the oxygen conditioning module 10 on the temperature of the modified atmosphere container.

[0295] When the cumulative working time of the oxygen conditioning module 10 reaches the preset time, the oxygen conditioning in the modified atmosphere container 20 ends, the oxygen conditioning module 10 is turned off, and the cycle ends.

[0296] Preferably, the first preset value T_rise is less than or equal to the second preset value T_fall. This ensures that the temperature of the modified atmosphere container generally shows a downward trend, preventing the temperature of the modified atmosphere container from becoming too high and ensuring that the temperature of the modified atmosphere container fluctuates within a certain range.

[0297] Referring to Figure 24, in another embodiment, adjusting the operating rate of the oxygen regulation module 10 based on the module temperature and changes in module temperature includes the following steps:

[0298] Determine if the module temperature is greater than the fourth threshold T1.

[0299] If so, adjust the oxygen regulation module 10 to operate at the first operating rate;

[0300] If not, determine whether the module temperature change exceeds the first speed threshold ΔT1.

[0301] If so, adjust the oxygen regulation module 10 to operate at the first operating rate;

[0302] If not, adjust the oxygen adjustment module 10 to operate at the second operating rate;

[0303] The first startup rate is lower than the second startup rate.

[0304] The module temperature is detected by a first temperature sensor. When the module temperature is greater than the fourth threshold T1, the oxygen regulation module 10 is adjusted to operate at a first operating rate. When the module temperature is less than or equal to the fourth threshold T1, the temperature change of the oxygen regulation module 10 is calculated. When the temperature change is greater than the first speed threshold ΔT1, the oxygen regulation module 10 is adjusted to operate at the first operating rate; when the temperature change is less than or equal to the first speed threshold ΔT1, the oxygen regulation module 10 is adjusted to operate at a second operating rate.

[0305] In this embodiment, the first start-up rate is 50%, meaning that the oxygen regulating module 10 starts for time A, then shuts down, waits for time A, and then starts up again, repeating this process. The second start-up rate is 100%, meaning that the oxygen regulating module 10 is always on. Of course, the first and second start-up rates can also be adjusted adaptively.

[0306] When the module temperature is greater than the fourth threshold T1 or the module temperature change is greater than the first speed threshold ΔT1, in order to reduce the impact of the oxygen conditioning module 10 on the temperature inside the controlled atmosphere container 20, the oxygen conditioning module 10 operates at the first start-up rate.

[0307] When the module temperature is less than or equal to the fourth threshold T1 and the module temperature change is less than or equal to the first speed threshold ΔT1, the oxygen regulating module 10 has little impact on the temperature inside the controlled atmosphere container 20, and the oxygen regulating module 10 can be kept open.

[0308] Understandably, the oxygen control module 10 does not always operate at the first or second operating rate. Every set time, the operating rate is readjusted based on the module temperature and its changes, thereby maximizing the operating efficiency of the oxygen control module 10 while reducing its impact on the temperature of the controlled atmosphere container 20.

[0309] In this embodiment, a fifth threshold T2 can also be set for the modified atmosphere container 20. When the second temperature sensor detects that the temperature of the modified atmosphere container is greater than the fifth threshold T2, the oxygen regulation module 10 is immediately shut down, causing the temperature of the modified atmosphere container to drop. The oxygen regulation module 10 is restarted when the temperature of the modified atmosphere container is lower than the sixth threshold T3. This prevents the temperature of the modified atmosphere container from becoming too high.

[0310] Referring to Figure 25, in another embodiment, adjusting the operating rate of the oxygen conditioning module 10 based on the temperature of the controlled atmosphere container and changes in the temperature of the controlled atmosphere container includes the following steps:

[0311] Determine whether the temperature of the controlled atmosphere container is greater than the fifth threshold T2.

[0312] If so, shut down the oxygen control module 10, and start the oxygen control module 10 when the temperature of the controlled atmosphere container is lower than the sixth threshold T3;

[0313] If not, determine whether the temperature change in the controlled atmosphere container exceeds the second velocity threshold ΔT2.

[0314] If so, adjust the oxygen regulation module 10 to operate at the first operating rate;

[0315] If not, adjust the oxygen adjustment module 10 to operate at the second operating rate;

[0316] The first startup rate is lower than the second startup rate.

[0317] The controlled atmosphere container temperature is detected by a second temperature sensor. When the controlled atmosphere container temperature exceeds the fifth threshold T2, the oxygen control module 10 is shut down, causing the controlled atmosphere container temperature to drop. Once the controlled atmosphere container temperature falls below the sixth threshold T3, the oxygen control module 10 is restarted. This prevents the controlled atmosphere container temperature from becoming too high.

[0318] During the activation of the oxygen regulation module 10, the temperature change of the controlled atmosphere container 20 is calculated. When the temperature change of the controlled atmosphere container is greater than the second speed threshold ΔT2, the oxygen regulation module 10 is adjusted to operate at the first activation rate. When the temperature change of the controlled atmosphere container is less than or equal to the second speed threshold ΔT2, the oxygen regulation module 10 is adjusted to operate at the second activation rate.

[0319] In this embodiment, the first start-up rate is 50%, meaning that the oxygen regulating module 10 starts for time A, then shuts down, waits for time A, and then starts up again, repeating this process. The second start-up rate is 100%, meaning that the oxygen regulating module 10 is always on. Of course, the first and second start-up rates can also be adjusted adaptively.

[0320] When the temperature of the controlled atmosphere container is less than or equal to the fifth threshold T2 and the temperature change of the controlled atmosphere container is greater than the second speed threshold ΔT2, in order to reduce the influence of the oxygen control module 10 on the temperature inside the controlled atmosphere container 20, the oxygen control module 10 operates at the first start-up rate.

[0321] When the temperature of the modified atmosphere container is less than or equal to the fifth threshold T2 and the temperature change of the modified atmosphere container is less than or equal to the second speed threshold ΔT2, the oxygen control module 10 has little effect on the temperature inside the modified atmosphere container 20, and the oxygen control module 10 can be kept open.

[0322] Understandably, the oxygen control module 10 does not always operate at the first or second operating rate. Every set time, the operating rate is readjusted based on the temperature of the controlled atmosphere container and its changes, thereby maximizing the operating efficiency of the oxygen control module 10 while reducing its impact on the temperature of the controlled atmosphere container 20.

[0323] Referring to Figure 26, in another embodiment, adjusting the power of the oxygen regulation module 10 based on the module temperature and changes in module temperature includes the following steps:

[0324] Determine if the module temperature is greater than the fourth threshold T1.

[0325] If so, adjust the oxygen regulation module 10 to operate at the first power.

[0326] If not, determine whether the module temperature change exceeds the first speed threshold ΔT1.

[0327] If so, adjust the oxygen regulation module 10 to operate at the first power.

[0328] If not, adjust the oxygen regulation module 10 to operate at the second power.

[0329] The first power is less than the second power.

[0330] The only difference between this embodiment and the embodiment shown in Figure 24 is that this embodiment adjusts the power of the oxygen regulating module 10, rather than the operating rate.

[0331] In this embodiment, the first power is lower than the rated power of the oxygen regulating module 10, specifically 80% of the rated power. The second power is the rated power of the oxygen regulating module 10. Of course, the first and second powers can also be adjusted adaptively.

[0332] When the module temperature is greater than the fourth threshold T1 or the module temperature change is greater than the first speed threshold ΔT1, the oxygen conditioning module 10 operates at the first power to reduce the impact of the oxygen conditioning module 10 on the temperature inside the controlled atmosphere container 20.

[0333] When the module temperature is less than or equal to the fourth threshold T1 and the module temperature change is less than or equal to the first speed threshold ΔT1, the oxygen conditioning module 10 has little effect on the temperature inside the controlled atmosphere container 20, and the oxygen conditioning module 10 operates at the second power.

[0334] Referring to FIG27, in another embodiment, adjusting the power of the oxygen conditioning module 10 based on the temperature of the controlled atmosphere container and changes in the temperature of the controlled atmosphere container includes the following steps:

[0335] Determine whether the temperature of the controlled atmosphere container is greater than the fifth threshold T2.

[0336] If so, shut down the oxygen control module 10, and start the oxygen control module 10 when the temperature of the controlled atmosphere container is lower than the sixth threshold T3;

[0337] If not, determine whether the temperature change in the controlled atmosphere container exceeds the second velocity threshold ΔT2.

[0338] If so, adjust the oxygen regulation module 10 to operate at the first power.

[0339] If not, adjust the oxygen regulation module 10 to operate at the second power.

[0340] The first power is less than the second power.

[0341] The only difference between this embodiment and the embodiment shown in Figure 25 is that this embodiment adjusts the power of the oxygen regulating module 10, rather than the operating rate.

[0342] In this embodiment, the first power is lower than the rated power of the oxygen regulating module 10, specifically 80% of the rated power. The second power is the rated power of the oxygen regulating module 10. Of course, the first and second powers can also be adjusted adaptively.

[0343] When the temperature of the controlled atmosphere container is less than or equal to the fifth threshold T2 and the temperature change of the controlled atmosphere container is greater than the second speed threshold ΔT2, the oxygen control module 10 operates at the first power in order to reduce the influence of the oxygen control module 10 on the temperature inside the controlled atmosphere container 20.

[0344] When the temperature of the controlled atmosphere container is less than or equal to the fifth threshold T2 and the temperature change of the controlled atmosphere container is less than or equal to the second speed threshold ΔT2, the oxygen control module 10 has little effect on the temperature inside the controlled atmosphere container 20, and the oxygen control module 10 operates at the second power.

[0345] In some embodiments, when the oxygen regulating module 10 is running at a first operating rate or a first power, the fan runs at a first speed; when the oxygen regulating module 10 is running at a second operating rate or a second power, the fan runs at a second speed; wherein the first speed is greater than the second speed.

[0346] When the oxygen conditioning module 10 is running at the first start-up rate or the first power, it indicates that the temperature of the oxygen conditioning module 10 or the controlled atmosphere container 20 is high or the heating rate is fast. At this time, the speed of the fan is increased to accelerate the flow of cold air into the controlled atmosphere container 20 or to accelerate the air flow in the controlled atmosphere container 20, thereby reducing the influence of the oxygen conditioning module 10 on the temperature inside the controlled atmosphere container 20.

[0347] It should be specifically noted that when adjusting the operating rate or power of the oxygen regulating module 10 based on module temperature and its changes conflicts with adjusting the operating rate or power of the oxygen regulating module 10 based on the temperature of the modified atmosphere container and its changes, the adjustment criteria of the oxygen regulating module 10 can be used to improve its working efficiency; alternatively, the adjustment criteria of the modified atmosphere container 20 can be used to ensure minimal temperature fluctuations within the container. Preferably, the adjustment criteria of the modified atmosphere container 20 should be used.

[0348] Referring to Figure 28, in another embodiment, adjusting the power of the oxygen regulation module based on module temperature changes includes the following steps:

[0349] If the module temperature change is within the preset range, control the oxygen regulation module 10 to continue operating at the current power;

[0350] If the temperature change of the module exceeds the preset range, the current power of the oxygen regulation module 10 will be reduced by the first preset change value.

[0351] If the temperature change of the module is less than the preset range, the current power of the oxygen regulating module 10 will be increased by the second preset change value.

[0352] The operating power of the oxygen conditioning module 10 is dynamically adjusted by changing the module temperature, thereby ensuring that the oxygen conditioning module 10 does not heat up too quickly and dissipate a large amount of heat into the modified atmosphere container 20, thus reducing the impact of the oxygen conditioning module 10 on the temperature inside the modified atmosphere container 20.

[0353] In this embodiment, during initial operation, the oxygen regulation module 10 operates at a set power of 10W. The operating power of the oxygen regulation module 10 is adjusted every set time interval, which is 1 minute. If the module temperature change is within a preset range, the current power remains unchanged. If the module temperature change exceeds the preset range, the current power is reduced by a first preset change value. If the module temperature change is less than the preset range, the current power is increased by a second preset change value. The first preset change value is 0.1W, and the second preset change value is the same as the first preset change value.

[0354] It is understandable that the above judgment logic can be recombined to adjust the start-up rate or power of the oxygen regulation module 10, which will not be elaborated further in this application.

[0355] "Adjusting the power of oxygen regulation module 10" includes:

[0356] Obtain the operating current of the oxygen regulation module 10, and adjust the operating voltage of the oxygen regulation module 10 to the target power. The target power is the first power, the second power, the power after reducing the current power by a first preset change value, or the power after increasing the current power by a second preset change value.

[0357] The current operating power of the oxygen regulating module 10 can be obtained by detecting the operating current through the current detection device 90 and controlling the operating voltage through the control device 80. If it is necessary to reduce the operating power of the oxygen regulating module 10, the operating voltage of the oxygen regulating module 10 is adjusted through the control device 80; if it is necessary to increase the operating power of the oxygen regulating module 10, the operating voltage of the oxygen regulating module 10 is increased through the control device 80, and the operating current detected by the current detection device 90 is changed simultaneously.

[0358] Because the oxygen regulating module 10 generates a large amount of heat during operation, as the operating time of the oxygen regulating module 10 increases, its temperature rises while its resistance decreases, leading to an increase in the current of the oxygen regulating module 10. To avoid excessive current affecting the normal operation of the oxygen regulating module 10, or even causing damage to the oxygen regulating module 10...

[0359] Referring to Figures 31, 32, and 35, in some embodiments, the control method further includes:

[0360] Collect the real-time current of the oxygen regulation module 10;

[0361] Based on the real-time current, the voltage of the oxygen regulation module 10 is adjusted so that the real-time current does not exceed the preset range.

[0362] The current detection device 90 detects the real-time current of the oxygen regulation module 10 and transmits the detected real-time current to the control device 80. Based on the real-time current, the control device 80 adjusts the voltage of the oxygen regulation module 10. This ensures that the oxygen regulation module 10 operates with a suitable current and avoids excessive current in the oxygen regulation module 10.

[0363] "Adjusting the voltage of the oxygen regulation module 10 so that the real-time current does not exceed the preset range" includes:

[0364] If the real-time current is within the preset range, control the oxygen regulation module 10 to continue operating at the current voltage;

[0365] If the real-time current is greater than the preset range, reduce the current voltage of the oxygen adjustment module 10 until the real-time current is within the preset range; or reduce the current voltage of the oxygen adjustment module 10 by a preset change value.

[0366] When the real-time current I detected by the current detection device 90 is within the preset range, i.e., I1≤I≤I2, the current of the oxygen adjustment module 10 is within the appropriate range. There is no need to adjust the voltage of the oxygen adjustment module 10 through the control device 80, and the oxygen adjustment module 10 can continue to operate at the current voltage.

[0367] When the real-time current I detected by the current detection device 90 is greater than the maximum value of the preset range, i.e., I > I², the current of the oxygen regulating module 10 exceeds the preset range. To prevent the excessive current of the oxygen regulating module 10 from affecting its normal operation, the control device 80 reduces the preset change value of the current voltage of the oxygen regulating module 10, thereby reducing the current of the oxygen regulating module 10. Alternatively, the current voltage is reduced until the real-time current is less than or equal to the maximum value of the preset range, ensuring that the oxygen regulating module 10 operates with a suitable current and avoiding excessive current.

[0368] Specifically, "reducing the current voltage of the oxygen control module 10 by a preset change value" includes:

[0369] Obtain the module temperature of oxygen control module 10;

[0370] Calculate the temperature change of the oxygen regulation module 10 within the third preset time period;

[0371] Determine if the module temperature change exceeds the third speed threshold.

[0372] If so, reduce the current voltage of the oxygen control module 10 by the third preset change value;

[0373] If not, reduce the current voltage of the oxygen control module 10 by the fourth preset change value;

[0374] Among them, the third preset change value is greater than the fourth preset change value.

[0375] The temperature of the oxygen-regulating module 10 is detected by a temperature sensor, and the temperature change of the oxygen-regulating module 10 within a third preset time period is calculated to obtain the heating rate of the oxygen-regulating module 10. When the temperature change of the module is greater than a third speed threshold, the current voltage of the oxygen-regulating module 10 is reduced by a third preset change value; when the temperature change of the module is less than or equal to the third speed threshold, the current voltage of the oxygen-regulating module 10 is reduced by a fourth preset change value.

[0376] When the module temperature change exceeds the third speed threshold, it indicates that the oxygen regulation module 10 is heating up rapidly, significantly impacting its current. This causes the current voltage of the oxygen regulation module 10 to be reduced by the third preset change value, thus preventing overcurrent. When the module temperature change is less than or equal to the third speed threshold, it indicates that the oxygen regulation module 10 is heating up slowly, having a smaller impact on its current. This also causes the current voltage of the oxygen regulation module 10 to be reduced by the third preset change value, ensuring the oxygen regulation efficiency of the oxygen regulation module 10.

[0377] The third and fourth preset change values ​​can be adjusted according to the power adaptability of the oxygen adjustment module 10.

[0378] "Adjusting the voltage of the oxygen regulation module 10 so that the real-time current does not exceed the preset range" also includes:

[0379] If the real-time current is less than the preset range, increase the current voltage of the oxygen regulation module 10 until the real-time current is within the preset range; or increase the current voltage of the oxygen regulation module 10 by a preset change value.

[0380] When the real-time current I detected by the current detection device 90 is less than the minimum value of the preset range, i.e., I < I1, the current of the oxygen regulation module 10 is lower than the preset range. At this time, the current of the oxygen regulation module 10 is too low, affecting its oxygen regulation efficiency in the chamber 200. The control device 80 increases the preset change value of the current voltage of the oxygen regulation module 10, or increases the current voltage until the real-time current is greater than or equal to the minimum value of the preset range, thereby increasing the current of the oxygen regulation module 10 and ensuring that the oxygen regulation module 10 operates with a suitable current, avoiding excessively low current.

[0381] Specifically, "increasing the current voltage of the oxygen control module 10 by a preset change value" includes:

[0382] Obtain the module temperature of oxygen control module 10;

[0383] Calculate the temperature change of the oxygen regulation module 10 within the fourth preset time period;

[0384] Determine if the module temperature change exceeds the fourth speed threshold.

[0385] If so, increase the current voltage of the oxygen control module 10 by the fifth preset change value;

[0386] If not, increase the current voltage of the oxygen control module 10 by the sixth preset change value;

[0387] Among them, the fifth preset change value is less than the sixth preset change value.

[0388] The temperature of the oxygen regulation module 10 is detected by a temperature sensor, and the temperature change of the oxygen regulation module 10 within a fourth preset time period is calculated to obtain the heating rate of the oxygen regulation module 10. When the temperature change of the module is greater than the fourth speed threshold, the current voltage of the oxygen regulation module 10 is increased by a fifth preset change value; when the temperature change of the module is less than or equal to the fourth speed threshold, the current voltage of the oxygen regulation module 10 is increased by a sixth preset change value.

[0389] When the module temperature change exceeds the fourth speed threshold, it indicates that the oxygen regulation module 10 is heating up rapidly, significantly impacting its current. Therefore, the current voltage of the oxygen regulation module 10 is increased by the fifth preset change value to prevent overcurrent. When the module temperature change is less than or equal to the fourth speed threshold, it indicates that the oxygen regulation module 10 is heating up slowly, having little impact on its current. Therefore, the current voltage of the oxygen regulation module 10 is increased by the sixth preset change value to ensure its oxygen regulation efficiency.

[0390] The fifth and sixth preset change values ​​can be adjusted according to the power adaptability of the oxygen adjustment module 10.

[0391] Understandably, by periodically collecting the real-time current I detected by the oxygen regulation module 10 and transmitting it to the control device 80, the voltage of the oxygen regulation module 10 is adjusted according to the real-time current I at set intervals, thereby regulating the real-time current I of the oxygen regulation module 10. By dynamically adjusting the real-time current I of the oxygen regulation module 10, firstly, it is possible to effectively prevent the generation of large currents that could affect the normal operation of the oxygen regulation module 10; secondly, it is possible to improve the oxygen regulation efficiency of the oxygen regulation module 10.

[0392] The actual voltage value of the adjusted oxygen regulating module 10 is compared with the output voltage value of the control device 80 to determine whether they match. If the difference between the actual voltage value of the oxygen regulating module 10 and the output voltage value of the control device 80 is greater than the set value, the oxygen regulating module 10 is determined to be abnormal and is shut down.

[0393] During the adjustment of the voltage of the oxygen regulation module 10, the ratio of the voltage of the oxygen regulation module 10 to the real-time current I is also calculated.

[0394] Determine if the ratio is greater than the seventh threshold.

[0395] If so, turn off the oxygen regulation module 10 and add electrolyte into the oxygen regulation module 10;

[0396] If not, oxygen regulation module 10 continues to operate.

[0397] During the operation of the oxygen regulation module 10, the electrolyte in the electrolyte storage chamber 101 is continuously consumed. As the electrolyte is consumed, the resistance of the oxygen regulation module 10 continuously increases, causing the current of the oxygen regulation module 10 to decrease and affecting the oxygen regulation efficiency of the oxygen regulation module 10. When the ratio is greater than the seventh threshold, it indicates that the electrolyte level in the electrolyte storage chamber 101 is low, and electrolyte needs to be added to the electrolyte storage chamber 101.

[0398] In this embodiment, the resistance value of the oxygen regulation module 10 measured when the electrolyte in the electrolyte storage chamber 101 is 1 / 3 to 1 / 4 full can be used as the seventh threshold.

[0399] In some embodiments of this application, the method further includes determining whether the ratio is less than an eighth threshold. If so, it is determined that there is a short circuit risk, the operation of the oxygen regulating module 10 is immediately stopped, and an alarm is issued; if not, the oxygen regulating module 10 continues to operate. To avoid the excessive heat generated by the oxygen regulating module 10 during prolonged operation affecting the temperature inside the chamber 200, the oxygen regulating module 10 operates intermittently.

[0400] The continuous running time of the oxygen regulation module 10 is obtained, and it is determined whether the continuous running time has reached the fifth preset time. If not, the oxygen regulation module 10 continues to run; if so, the oxygen regulation module 10 is turned off, and the oxygen regulation module 10 is turned on again after the sixth preset time.

[0401] The oxygen adjustment module 10 is activated by the control device 80 to adjust the oxygen level. After the oxygen adjustment module 10 operates continuously for a fifth preset time, it is turned off. After a sixth preset time, the oxygen adjustment module 10 is activated again, and this process is repeated. Simultaneously, the cumulative activation time of the oxygen adjustment module 10 is calculated. When the cumulative activation time of the oxygen adjustment module 10 reaches the preset time, the oxygen adjustment operation of the oxygen adjustment module 10 ends, and it waits for the next oxygen adjustment. Preferably, the voltage of the oxygen adjustment module 10 when activated is a preset voltage, which is less than or equal to the rated voltage of the oxygen adjustment module 10.

[0402] In one specific embodiment, the control device 80 turns on the oxygen adjustment module 10 with the rated voltage, and at the same time, the current I of the oxygen adjustment module 10 is detected by the current detection device 90.

[0403] When the oxygen regulating module 10 is turned on at the rated voltage, the oxygen regulating efficiency of the oxygen regulating module 10 can be improved, and it is only necessary to prevent the current of the oxygen regulating module 10 from being too high.

[0404] When the real-time current I detected by the current detection device 90 is less than or equal to the maximum value of the preset range (i.e., I ≤ I2), the current of the oxygen adjustment module 10 is within a suitable range, and there is no need to adjust the voltage of the oxygen adjustment module 10 through the control device 80. When the real-time current I detected by the current detection device 90 is greater than the maximum value of the preset range (i.e., I > I2), the control device 80 reduces the current of the oxygen adjustment module 10, thereby reducing the current of the oxygen adjustment module 10 until the current of the oxygen adjustment module 10 is less than or equal to the maximum value of the preset range.

[0405] At set intervals, the current detection device 90 transmits the detected real-time current I to the control device 80. The control device 80 adjusts the voltage of the oxygen regulating module 10 according to the real-time current I, thereby ensuring that the current of the oxygen regulating module 10 is always within a suitable range.

[0406] In another specific embodiment, the control device 80 turns on the oxygen adjustment module 10 with a voltage lower than the rated voltage, and at the same time detects the real-time current I through the current detection device 90.

[0407] When the oxygen regulating module 10 is turned on with a voltage lower than the rated voltage, the voltage of the oxygen regulating module 10 is gradually adjusted according to the current feedback from the current detection device 90, which can reduce the current surge during initial power-on.

[0408] When the real-time current I is within the preset range (I1≤I≤I2), the current voltage of the oxygen regulating module 10 remains unchanged. When the real-time current I detected by the current detection device 90 is greater than the maximum value of the preset range (I>I2), the current current of the oxygen regulating module 10 exceeds the preset range, and the control device 80 reduces the preset change value of the current voltage of the oxygen regulating module 10. When the real-time current I detected by the current detection device 90 is less than the minimum value of the preset range (I<I1), the current current of the oxygen regulating module 10 is lower than the preset range, and the control device 80 increases the preset change value of the current voltage of the oxygen regulating module 10.

[0409] At set intervals, the current detection device 90 transmits the detected real-time current I to the control device 80. The control device 80 adjusts the voltage of the oxygen regulating module 10 according to the real-time current I, thereby ensuring that the current of the oxygen regulating module 10 is always within a suitable range.

[0410] In this embodiment, it is also included to determine whether the current voltage of the oxygen adjustment module 10 has reached the maximum set value. If so, the voltage is maintained at the maximum set value; if not, the voltage value is increased.

[0411] If, during the gradual increase of the voltage of the oxygen regulating module 10, the real-time current I remains below the minimum value within the preset range until the voltage reaches the maximum set value, then the voltage of the oxygen regulating module 10 will no longer be increased, and the voltage will remain at the maximum set value. The maximum set value is the rated voltage.

[0412] Referring to Figures 33 to 35, the only difference from the previous embodiment is that the current detection device 90 detects the sum of the real-time currents of the oxygen regulation module 10 and the control device 80, and adjusts the voltage of the oxygen regulation module 10 based on the sum of the real-time currents.

[0413] The control method also includes the following steps:

[0414] Obtain the sum of the real-time current of the control device 80 used to adjust the voltage of the oxygen adjustment module 10 and the oxygen adjustment module 10;

[0415] Based on the sum of real-time currents, the voltage of the oxygen regulation module 10 is adjusted so that the sum of real-time currents does not exceed a preset range.

[0416] "Adjusting the voltage of the oxygen regulation module 10 so that the sum of the real-time currents does not exceed a preset range" includes:

[0417] If the sum of the real-time currents is within the preset range, the oxygen regulation module 10 will continue to operate at the current voltage.

[0418] If the sum of real-time currents is greater than a preset range, reduce the current voltage of the oxygen adjustment module 10 until the sum of real-time currents is within the preset range; or reduce the current voltage of the oxygen adjustment module 10 by a preset change value.

[0419] When the sum of the real-time currents detected by the current detection device 90 is within the preset range, i.e., I3≤I and ≤I4, the current of the oxygen adjustment module 10 is within the appropriate range. There is no need to adjust the voltage of the oxygen adjustment module 10 through the control device 80, and the oxygen adjustment module 10 can continue to operate at the current voltage.

[0420] When the sum of real-time currents Isum detected by the current detection device 90 exceeds the maximum value of the preset range (i.e., Isum > I4), to prevent excessive current in the oxygen regulating module 10 from affecting its normal operation, the control device 80 reduces the preset change value of the current voltage of the oxygen regulating module 10, thereby reducing the current of the oxygen regulating module 10. Alternatively, the current voltage is reduced until the sum of real-time currents Isum is less than or equal to the maximum value of the preset range, ensuring that the oxygen regulating module 10 operates with a suitable current and avoiding excessive current.

[0421] "Reducing the current voltage of the oxygen control module 10 by a preset change value" also includes reducing the current voltage of the oxygen control module 10 by a third or fourth preset change value based on the module temperature change of the oxygen control module 10. The specific implementation is the same as in the previous embodiment, and will not be repeated here.

[0422] "Adjusting the voltage of the oxygen regulation module 10 so that the sum of the real-time currents does not exceed a preset range" also includes:

[0423] If the sum of real-time currents is less than a preset range, increase the current voltage of the oxygen regulation module 10 until the sum of real-time currents is within the preset range; or increase the current voltage of the oxygen regulation module 10 by a preset change value.

[0424] When the sum of real-time currents Isum detected by the current detection device 90 is less than the minimum value of the preset range, i.e., Isum < I3, the current of the oxygen regulation module 10 is too low, affecting its oxygen regulation efficiency in the chamber 200. The control device 80 increases the preset change value of the current voltage of the oxygen regulation module 10, or increases the current voltage until the sum of real-time currents Isum is greater than or equal to the minimum value of the preset range, thereby increasing the current of the oxygen regulation module 10 and ensuring that the oxygen regulation module 10 operates with an appropriate current, avoiding excessively low current.

[0425] "Increasing the current voltage of the oxygen control module 10 by a preset change value" also includes increasing the current voltage of the oxygen control module 10 by a fifth or sixth preset change value based on the module temperature change of the oxygen control module 10. The specific implementation is the same as in the previous embodiment, and will not be repeated here.

[0426] During the process of adjusting the voltage of the oxygen adjustment module 10, the ratio of the sum of the voltage and the real-time current I of the oxygen adjustment module 10 is also calculated.

[0427] Determine if the ratio is greater than the seventh threshold.

[0428] If so, turn off the oxygen regulation module 10 and add electrolyte into the oxygen regulation module 10;

[0429] If not, oxygen regulation module 10 continues to operate.

[0430] During the operation of the oxygen regulation module 10, the electrolyte in the electrolyte storage chamber 101 is continuously consumed. As the electrolyte is consumed, the resistance of the oxygen regulation module 10 continuously increases, causing the current of the oxygen regulation module 10 to decrease and affecting the oxygen regulation efficiency of the oxygen regulation module 10. When the ratio is greater than the seventh threshold, it indicates that the electrolyte level in the electrolyte storage chamber 101 is low, and electrolyte needs to be added to the electrolyte storage chamber 101.

[0431] In this embodiment, the resistance value of the oxygen regulation module 10 measured when the electrolyte in the electrolyte storage chamber 101 is 1 / 3 to 1 / 4 full can be used as the seventh threshold.

[0432] In some embodiments of this application, it is also included to determine whether the ratio is less than an eighth threshold. If so, it is determined that there is a short circuit risk, the operation of the oxygen adjustment module 10 is stopped immediately, and an alarm is issued; if not, the oxygen adjustment module 10 continues to operate.

[0433] The control device 80 can also turn on the oxygen adjustment module 10 at the rated voltage or at a voltage lower than the rated voltage. The control method is the same as in the previous embodiment, and will not be described again here.

[0434] Referring to FIG37, in order to accurately adjust the oxygen concentration in the modified atmosphere container 20, in some embodiments, the control method includes the following steps:

[0435] Upon receiving an oxygen adjustment command, the oxygen adjustment module 10 is activated to prepare oxygen-adjusted gas, which is then delivered to the modified atmosphere container 20 connected to the oxygen adjustment module 10. In this embodiment, if the oxygen adjustment module 10 is in an on state before receiving the oxygen adjustment command, it remains on after receiving the command. Activating the oxygen adjustment module 10 includes starting the power supply to supply power to the electrode assembly.

[0436] The operating current I0 of the electrode assembly is acquired at a preset time interval t1, and the preset operating time t2 required for the oxygen regulation module 10 to operate is determined based on the operating current I0 of the electrode assembly. In this embodiment, after the electrode assembly is powered by the power supply, the operating current I0 of the electrode assembly can be acquired through the current detection device, that is, the real-time operating current value of the electrode assembly can be obtained.

[0437] The oxygen regulation module 10 is controlled to run for a preset time t2. In this embodiment, controlling the oxygen regulation module 10 to run for a preset time t2 means controlling the electrode assembly to run for a preset time t2.

[0438] By acquiring the operating current I0 of the electrode assembly, the amount of a specific gas (e.g., oxygen) that the oxygen conditioning module 10 can process (i.e., increase or consume) within time t1 can be calculated. This allows for the calculation of the operating time t2 required for the oxygen conditioning module 10 to reach the preset concentration of the specific gas in the modified atmosphere container 20, thereby enabling accurate adjustment of the concentration of the specific gas in the modified atmosphere container 20.

[0439] Specifically, the amount of a specific gas that the oxygen-regulating module 10 can process within a unit time t1 is determined based on the operating current I0 of the electrode assembly, and the preset time t2 is determined based on the volume of the modified atmosphere container 20. In this embodiment, after calculating the amount of a specific gas (e.g., the number of gas molecules) that can be processed within a unit time t1 based on the operating current I0 of the electrode assembly, the amount of this specific gas is converted into volume, and then the preset time t2 required to reach the preset concentration is calculated based on the volume of the modified atmosphere container 20, for example, calculating how many times t1 it will take to reach the preset concentration.

[0440] Furthermore, based on the temperature T0 inside the modified atmosphere container 20, the volume of a specific gas that the oxygen regulation module 10 can process within a unit time t1 is determined. In this embodiment, after determining the amount of a specific gas (e.g., the number of gas molecules) that can be processed within a unit time t1, the volume of the specific gas being processed can be accurately determined by combining it with the temperature T0 inside the modified atmosphere container 20. This allows for the accurate calculation of the preset time t2 required to reach the preset concentration, making the actual concentration of the specific gas inside the modified atmosphere container 20 closer to the preset concentration, and enabling the oxygen regulation module 10 to adjust the gas concentration more accurately.

[0441] In some embodiments, only the volume of the modified atmosphere container 20 can be considered, thereby simplifying the control procedure. For example, when the effect of the temperature T0 inside the modified atmosphere container 20 is not considered, it can be set to a fixed value, such as the operating temperature under normal conditions, thus eliminating the need for temperature detection and simplifying the control procedure.

[0442] In other embodiments, factors affecting gas concentration may be other than the temperature T0 inside the modified atmosphere container 20 (e.g., the sealing performance of the modified atmosphere container 20). To simplify the procedure, the sealing performance can also be controlled to a fixed value, for example, assuming that the modified atmosphere container 20 is in equilibrium with the external space air pressure.

[0443] In some embodiments, t2 = n × t1, where n is a positive integer. When the operating current I0 obtained in each time interval t1 is the same, the amount of specific gas added or consumed in each time interval t1 is the same, and the preset time t2 is fixed, thereby simplifying control.

[0444] In other embodiments, when the operating current I0 is different in each time interval t1 (for example, the operating voltage of the electrode group is large when it is first started, and the operating voltage of the electrode group gradually decreases as the operating time of the electrode group increases), the difference in operating current I0 causes the amount of specific gas processed in each time interval t1 to be different. At this time, the preset time t2 can be adjusted in real time according to the time interval t1. The preset time t2 is changed in real time.

[0445] Of course, the final preset time t2 is obtained by adding all the time intervals t1, that is, t2 = ∑t1 = n × t1.

[0446] It should be noted that when the time interval t1 is small, the error between the instantaneous current value and the average current within the time interval t1 is small and can be ignored.

[0447] Specifically, when the electrode assembly is running, the operating current I0 is acquired using a current detection device. The operating current I0 is detected every time interval t1. Based on the current value, the cumulative increase or consumption of a specific gas molecule within time t1 can be calculated. The volume of this specific gas is calculated based on the temperature T0 inside the modified atmosphere container 20 and the number of added or consumed gas molecules. Then, the actual concentration of the specific gas in the modified atmosphere container 20 after time t1 is calculated based on its volume. After accumulating multiple time intervals t1 (e.g., n time intervals t1), the concentration of the specific gas reaches a preset concentration, thus determining the preset time t2 (i.e., n × t1). n is a positive integer, simplifying the operating procedure.

[0448] In other embodiments, n may not be an integer, such as n = 0.5, 1.8, etc., that is, the preset concentration can be reached after running for 0.5 or 1.8 time t1, thereby improving the accuracy of the oxygen adjustment module 10 in adjusting the gas concentration.

[0449] For example, after acquiring the operating current I0 of the electrode assembly at a preset time interval t1, based on the corresponding relationship (e.g., a linear relationship with coefficient k) between the amount of specific gas added or consumed by the oxygen regulation module 10 (e.g., the number of molecules) and the operating current I0 of the electrode assembly, the number of specific gas molecules added or consumed per unit time t1 can be calculated as N, where N = k × I0 × t1. After acquiring the temperature T0 inside the modified atmosphere container 20, the volume V0 of the specific gas added or consumed per unit time t1 can be calculated based on the temperature T0 inside the modified atmosphere container 20, where V0 = N / N1 = k × I0 × t1 / N1, and N1 is the number of specific gas molecules contained in a unit volume at temperature T0 inside the modified atmosphere container 20. The cumulative increase in the volume V of the specific gas within time t2 is V = ∑k × I0 × t1 / N1 = n × k × I0 × t1 / N1. When the proportion of the specific gas volume V in the modified atmosphere container 20 meets the concentration requirement, the preset time t2 can be determined.

[0450] Furthermore, based on the sealing method of the modified atmosphere container 20, a corresponding calculation method is selected to obtain the preset time t2. In this embodiment, considering that the sealing condition of the modified atmosphere container 20 affects the concentration of a specific gas inside the modified atmosphere container 20, the sealing method of the modified atmosphere container 20 is also taken into account when calculating the preset time t2, thereby meeting more application scenarios and improving the accuracy of the oxygen regulation module 10 in regulating a specific gas. To simplify the program, the sealing methods of the modified atmosphere container 20 can be distinguished and refined. Depending on the sealing method of the modified atmosphere container 20, the corresponding control program can be manually or automatically selected. When the control program is automatically selected, a corresponding sealing method sensor (e.g., a pressure sensor) can be set to detect which sealing method the modified atmosphere container 20 uses.

[0451] Specifically, when the modified atmosphere container 20 is configured with the first sealing method, the internal air pressure of the modified atmosphere container 20 is greater than or less than the external air pressure. In this embodiment, when the modified atmosphere container 20 is configured with the first sealing method, the modified atmosphere container 20 can only communicate with the airflow of the oxygen control module 10 and cannot communicate with the external environment. Therefore, when the modified atmosphere container 20 constitutes a low-temperature, low-oxygen space, i.e., a low-oxygen environment, the consumption of oxygen (i.e., a specific gas) will cause a negative pressure to form inside the modified atmosphere container 20. When the modified atmosphere container 20 constitutes a low-temperature, high-oxygen space, i.e., a high-oxygen environment, the increase of oxygen (i.e., a specific gas) will cause a positive pressure to form inside the modified atmosphere container 20.

[0452] Specifically, when the modified atmosphere container 20 is configured with the first sealing method, the preset time t2 is obtained by selecting the first calculation method.

[0453] For example, when calculating the preset time t2 of the low-temperature, high-oxygen space using the first calculation method: the volume of the modified atmosphere container 20 is obtained as V2, the initial oxygen volume inside the modified atmosphere container 20 is V3, V3 = V2 × 20.9%, and the oxygen content in the modified atmosphere container 20 after the oxygen regulation module 10 runs for t2 is P_high = (V + V3) / V2. The preset time t2 is deduced by using the time required for P_high to reach the preset concentration. When calculating the preset time t2 of the low-temperature, low-oxygen space using the first calculation method: P_low = (V3 - V) / V2, the preset time t2 is deduced by using the time required for P_low to reach the preset concentration.

[0454] Specifically, when the modified atmosphere container 20 is configured with the second sealing method, the air pressure inside the modified atmosphere container 20 is equal to the air pressure outside the modified atmosphere container 20. In this embodiment, when the modified atmosphere container 20 is configured with the second sealing method, the modified atmosphere container 20 can communicate with the external environment with a small amount of airflow to maintain the pressure balance between the modified atmosphere container 20 and the external environment.

[0455] At this point, an air replenishment calculation is introduced. The low-temperature, low-oxygen space, having lost oxygen, is replenished with a corresponding volume of air from the outside. This change in air volume causes a change in the oxygen concentration within the controlled atmosphere container 20. Since the volumes of gas exchanged inside and outside are equal, the actual oxygen concentration can be calculated, and the preset time t2 can then be deduced. Similarly, when a corresponding volume of oxygen enters the low-temperature, high-oxygen space, a corresponding volume of mixed gas will also be discharged.

[0456] Specifically, when the modified atmosphere container 20 is configured with the second sealing method, the preset time t2 is obtained by selecting the second calculation method.

[0457] For example, when calculating the preset time t2 of the low-temperature, high-oxygen space using the second calculation method: Phigh = (V0 + V3 - (V0 × (V0 + V3) / V2)) / V2, the preset time t2 is deduced from the time required for Phigh to reach the preset concentration. When calculating the preset time t2 of the low-temperature, low-oxygen space using the second calculation method: Plow = (V3 - V0 + (V0 × 20.9%)) / V2, the preset time t2 is deduced from the time required for Plow to reach the preset concentration.

[0458] Specifically, the refrigeration equipment has a refrigeration chamber 70. When the modified atmosphere container 20 is configured with a third sealing method, the air pressure inside the modified atmosphere container 20 is equal to the air pressure outside the modified atmosphere container 20, and the airflow of the modified atmosphere container 20 is connected to the refrigeration chamber 70. In this embodiment, when the modified atmosphere container 20 is configured with a third sealing method, the modified atmosphere container 20 can have a small amount of airflow communication with the external environment to maintain the pressure balance between the modified atmosphere container 20 and the external environment, while there is a certain amount of gas exchange between the modified atmosphere container 20 and the refrigeration chamber 70.

[0459] At this point, it is only necessary to increase the airflow exchange between the cooling room 70 and the second calculation method.

[0460] Specifically, when the modified atmosphere container 20 is configured with the third sealing method, the preset time t2 is obtained by selecting the third calculation method.

[0461] For example, when calculating the preset time t2 of the low-temperature, high-oxygen space using the third calculation method: obtain the air volume exchanged between the controlled atmosphere container 20 and the refrigeration chamber 70 within a unit time t1 as V4 (excluding the pressure balance portion), with an oxygen content of 20.9%. The oxygen volume of this exchanged gas is V5 = 20.9% × V4. P_high = (V0 + V3 + V5 - ((V0 + V4) × (V0 + V3) / V2)) / V2. The preset time t2 is deduced by using the time required for P_high to reach the preset concentration. When calculating the preset time t2 of the low-temperature, low-oxygen space using the third calculation method: P_low = (V3 - V0 + (V0 × 20.9%) + V5) / V2. The preset time t2 is deduced by using the time required for P_low to reach the preset concentration.

[0462] In some embodiments, the oxygen regulation module 10 is stopped after running for a preset time t2. In this embodiment, the oxygen regulation module 10 is directly stopped after running for the preset time t2, that is, after the electrode group's running time reaches the preset time t2. This eliminates the need to use a gas concentration sensor to sense the concentration of a specific gas in the modified atmosphere container 20, simplifying the control procedure. Therefore, by running the oxygen regulation module 10 for the preset time t2, the concentration of a specific gas in the modified atmosphere container 20 can reach a preset concentration, eliminating the need for a gas concentration sensor in the refrigeration equipment and simplifying its structure.

[0463] In other embodiments, after the oxygen regulating module 10 has been running for a preset time t2, if the concentration of a specific gas in the modified atmosphere container 20 reaches a preset concentration, the oxygen regulating module 10 is controlled to stop operating. In this embodiment, after the oxygen regulating module 10 has been running for a preset time t2, a gas concentration sensor is used for detection. If the concentration in the modified atmosphere container 20 has not reached the preset concentration (for example, the concentration of a specific gas in a low-temperature, low-oxygen space is greater than the preset concentration, or the concentration of a specific gas in a low-temperature, high-oxygen space is less than the preset concentration), the oxygen regulating module 10 is controlled to continue operating until the preset concentration is reached.

[0464] By adding a concentration detection step, it can be ensured that the actual concentration in the modified atmosphere container 20 meets the preset concentration, thereby improving the accuracy of the oxygen control module 10 in adjusting the concentration of a specific gas and adapting to actual usage scenarios. For example, if the modified atmosphere container 20 is opened to exchange gases with the external environment during the operation of the oxygen control module 10, or if the electrochemical reaction is unstable (e.g., lack of electrolyte), the actual concentration of a specific gas in the modified atmosphere container 20 may not reach the preset concentration after the oxygen control module 10 has been running for a preset time t2.

[0465] At this point, the current concentration of a specific gas in the modified atmosphere container 20 can be obtained through a gas concentration sensor, and the concentration difference between the current concentration and the preset concentration can be calculated. Based on the operating current I0, the preset time t2 of the next round can be calculated, that is, how many time intervals t1 are needed, so that the actual concentration of the specific gas in the modified atmosphere container 20 eventually reaches the preset concentration.

[0466] Specifically, the oxygen adjustment command refers to:

[0467] The oxygen regulation module 10 can be activated by a start signal or by a concentration adjustment signal. In this embodiment, after receiving the start signal, the oxygen regulation module 10 is activated to adjust the specific gas concentration in the modified atmosphere container 20, i.e., the electrode assembly is activated. The concentration adjustment signal can be to activate the oxygen regulation module 10 for a new round of gas concentration adjustment, or it can be to control the operating oxygen regulation module 10 to change its power, i.e., to change the operating voltage or current of the electrode assembly, thereby adjusting the existing concentration to meet different oxygen regulation needs.

[0468] Furthermore, after the oxygen regulating module 10 has been running for a preset time t2, when the cumulative running time of the oxygen regulating module 10 reaches a preset time t3, an abnormal signal is issued. In this embodiment, when the oxygen regulating module 10 has been running for a preset time t2, and the cumulative running time of the oxygen regulating module 10 reaches t3 (e.g., the maximum maximum running time limit of the oxygen regulating module 10), if the oxygen regulating module 10 is still running, it indicates that the concentration of a specific gas in the modified atmosphere container 20 has not yet reached the preset concentration, indicating that there is an abnormality in the oxygen regulating module 10 (e.g., leakage in the modified atmosphere container 20, leakage of electrolyte preventing electrochemical reaction, etc.). At this time, an abnormal signal is issued, and the abnormality is displayed on the display device and sent to the cloud to remind the user to report the abnormality in time. In addition, the oxygen regulating module 10 can also be controlled to stop running to prevent the oxygen regulating module 10 from continuing to work and causing damage.

[0469] Furthermore, when the temperature T0 inside the modified atmosphere container 20 is lower than the preset temperature T1, the oxygen control module 10 is controlled to execute a temperature maintenance command. In this embodiment, considering that the electrochemical reaction efficiency of the oxygen control module 10 will decrease at low temperatures, when the temperature T0 inside the modified atmosphere container 20 is lower than the preset temperature T1, the temperature maintenance command is executed to raise the temperature, thereby avoiding low temperatures inside the modified atmosphere container 20 while ensuring the efficiency of the electrochemical reaction.

[0470] Furthermore, when the liquid temperature T2 in the electrolyte storage chamber 13 or the temperature T0 in the modified atmosphere container 20 is higher than the preset temperature T3, the oxygen regulation module 10 is controlled to stop executing the temperature maintenance command. In this embodiment, when the liquid temperature T2 in the electrolyte storage chamber (e.g., the temperature of the electrolyte) or the temperature T0 in the modified atmosphere container 20 is higher than the preset temperature T3, there is no need to execute the temperature maintenance command, thereby saving energy.

[0471] Furthermore, after obtaining the oxygen adjustment command, the oxygen adjustment module 10 is controlled to stop executing the temperature maintenance command. In this embodiment, when the oxygen adjustment command is obtained, i.e., the start signal or concentration adjustment signal of the oxygen adjustment module 10, the oxygen adjustment command is executed first, regardless of whether the temperature maintenance command is being executed, to ensure the oxygen adjustment requirements of the modified atmosphere container 20.

[0472] Specifically, the temperature maintenance command refers to:

[0473] The oxygen regulation module 10 is controlled to run for a preset time t4 at a preset time interval t3. In this embodiment, the temperature maintenance command includes: controlling the oxygen regulation module 10 to run for t4 at each time interval t3. The heat generated by the operation of the oxygen regulation module 10, i.e., the heat generated by the operation of the electrode group, is used and connected to the modified atmosphere container 20 through the airflow of the oxygen regulation module 10 to prevent the modified atmosphere container 20 from being at a low temperature, i.e., to avoid it being below T0 < T1.

[0474] The operating time t4 of the oxygen conditioning module 10 can be set according to the oxygen conditioning module 10's ability to process specific gases (such as the operating current or operating voltage of the electrode group), the volume of the modified atmosphere container 20, and the sealing condition of the modified atmosphere container 20.

[0475] Furthermore, when the liquid temperature T2 in the electrolyte storage chamber 13 or the temperature T0 in the modified atmosphere container 20 is lower than a preset temperature T4, the oxygen regulation module 10 is controlled to execute a current maintenance command. After the operating current I0 of the electrode group is greater than a preset current I1, the oxygen regulation module 10 is controlled to stop executing the current maintenance command. In this embodiment, the current maintenance command includes: controlling the oxygen regulation module 10 to run continuously, or controlling the oxygen regulation module 10 to run for a preset time t6 at a preset time interval t5. To avoid a decrease in the operating current of the electrode group leading to a reduction in the electrochemical reaction efficiency of the oxygen regulation module 10, the operating current is determined by sensing the liquid temperature T2 in the electrolyte storage chamber 13 or the temperature T0 in the modified atmosphere container 20, i.e., determining whether T0 < T4 or T2 < T4. By activating the current maintenance command of the oxygen regulation module 10, such as controlling the oxygen regulation module 10 to run continuously, the operating current of the electrode group is increased, thereby ensuring the efficiency of the electrochemical reaction.

[0476] It should be noted that the temperature sustaining command and the current sustaining command can be related by "OR", and their priority can be set as needed. For example, if temperature needs to be maintained first, the temperature sustaining command can be selected first; if operating current needs to be maintained first, the current sustaining command can be selected first. In this case, the preset temperature T1 and preset temperature T3 can be the same without causing a conflict between the temperature sustaining command and the current sustaining command. Of course, the temperature sustaining command and the current sustaining command can also be related by "AND", in which case the preset temperature T1 and T3 can be different to avoid a conflict between the temperature sustaining command and the current sustaining command.

[0477] Referring to Figure 37, another preferred embodiment of this application provides a control method for an instruction device, the control method comprising the following steps:

[0478] When the temperature T0 inside the controlled atmosphere container 20 is lower than the preset temperature T1, the oxygen control module 10 is controlled to execute a temperature maintenance command.

[0479] Upon receiving the oxygen adjustment command, the oxygen adjustment module 10 is activated, and the oxygen adjustment gas is delivered to the modified atmosphere container 20 connected to the oxygen adjustment module 10.

[0480] After the oxygen regulation module 10 has been running for a preset time t2, the oxygen regulation module 10 is controlled to stop running.

[0481] In this embodiment, the temperature maintenance command is executed during the interval between the oxygen adjustment command and the oxygen adjustment command, such as before or after the oxygen adjustment command is executed. When the oxygen adjustment module 10 is in the off state, the temperature maintenance command can be used to maintain the temperature T0 inside the controlled atmosphere container 20, thereby ensuring the efficiency of the electrochemical reaction, until the oxygen adjustment command is executed, that is, the oxygen adjustment command takes precedence over the temperature maintenance command.

[0482] Of course, in other embodiments, the temperature maintenance command can also be independent of the oxygen adjustment command. As long as the temperature T0 inside the modified atmosphere container 20 is determined to be lower than the preset temperature T1, the temperature maintenance command can be executed, regardless of whether it is in the oxygen adjustment command, so as to avoid the inside of the modified atmosphere container 20 being at a low temperature.

[0483] Preferably, after the oxygen conditioning module 10 has been running for a preset time t2, that is, after the electrode group has been running for a preset time t2, the oxygen conditioning module 10 is directly controlled to stop running, without the need to use the gas concentration sensor 20 to sense the concentration of a specific gas in the modified atmosphere container 20, thus simplifying the control procedure.

[0484] Referring to Figure 38, a preferred embodiment of this application provides a control method for a refrigeration device, the control method comprising the following steps:

[0485] When the liquid temperature T2 in the electrolyte storage chamber 13 or the temperature T0 in the modified atmosphere container 20 is lower than the preset temperature T4, the oxygen regulation module 10 is controlled to execute the current maintenance command.

[0486] Upon receiving the oxygen adjustment command, the oxygen adjustment module 10 is activated, and the oxygen adjustment gas is delivered to the modified atmosphere container 20 connected to the oxygen adjustment module 10.

[0487] After the oxygen regulation module 10 has been running for a preset time t2, the oxygen regulation module 10 is controlled to stop running.

[0488] In this embodiment, the current sustaining command is executed during the interval between the oxygen adjustment command and the oxygen adjustment command, such as before or after the oxygen adjustment command is executed. When the oxygen adjustment module 10 is in the off state, the current sustaining command can be used to maintain the operating current I0 of the electrode group, thereby ensuring the efficiency of the electrochemical reaction, until the oxygen adjustment command is executed, that is, the oxygen adjustment command takes precedence over the current sustaining command.

[0489] Of course, in other embodiments, the current maintenance command can also be independent of the oxygen adjustment command. As long as the liquid temperature T2 in the electrolyte storage chamber 13 or the temperature T0 in the modified atmosphere container 20 is lower than the preset temperature T4, that is, when T0 < T4 or T2 < T4, the current maintenance command can be executed, regardless of whether it is in the oxygen adjustment command, so as to avoid the operating current of the electrode group being too low and affecting the efficiency of the electrochemical reaction.

[0490] In addition, preferably, after the oxygen conditioning module 10 has been running for a preset time t2, that is, after the electrode group has been running for a preset time t2, the oxygen conditioning module 10 is directly controlled to stop running, without the need to use the gas concentration sensor 20 to sense the concentration of a specific gas in the modified atmosphere container 20, thus simplifying the control procedure.
