Description

Technical Field

[0001] This invention relates to a refrigeration device, and more particularly to a method for regulating oxygen in a refrigeration device. Background Technology

[0002] Existing refrigeration equipment typically employs a single temperature control method, directly cooling the storage space through the refrigeration system to meet the preservation needs of food. However, some fruits and vegetables maintain their freshness better in low-oxygen environments. Low-oxygen environments effectively inhibit respiration and slow down spoilage, thus improving the preservation quality of fruits and vegetables. Therefore, the market demand for refrigeration equipment capable of providing low-oxygen environments is gradually increasing.

[0003] However, there may be some issues between oxygen regulation and refrigeration in the refrigeration equipment. Since the oxygen regulation chamber needs to be relatively isolated from other environments within the refrigeration equipment to form a relatively sealed space, the temperature within this space is affected by both indirect refrigeration from the cold air outside the space and the temperature of the oxygen regulation gas itself. If these two cold sources are not properly coordinated, the internal temperature of the space may become too high or too low during use. Furthermore, the internal temperature cannot be independently and precisely controlled during oxygen regulation, or other areas within the refrigeration equipment may become too cold in order to refrigerate the oxygen regulation chamber. These situations can range from affecting the overall preservation effect to causing food to freeze or spoil, all of which will impact the user experience. Summary of the Invention

[0004] To address the coordination problem between oxygen regulation and refrigeration in the aforementioned prior art, the present invention aims to provide a refrigeration device and its oxygen regulation method that can ensure the preservation of food in a suitable oxygen concentration and temperature environment.

[0005] To achieve the above-mentioned objectives, one embodiment of the present invention provides a refrigeration device.

[0006] A humidity sensor is used to continuously monitor the temperature of the oxygen conditioning room and the temperature of the cooling room during the operation of the oxygen conditioning module. The oxygen conditioning module is used to adjust the oxygen concentration in the oxygen conditioning room, and the cooling component is used to supply the cooling capacity generated by the cooling system to the oxygen conditioning room and the cooling room. The cooling component cools the oxygen conditioning room in the first operating state.

[0007] The processing module is used to control the refrigeration system to shut down and switch the cooling component to the first operating state when the temperature of the refrigeration chamber is lower than the high temperature threshold for refrigeration and the temperature of the oxygen conditioning chamber is higher than the oxygen conditioning temperature threshold.

[0008] To achieve one of the above-mentioned objectives, an embodiment of the present invention provides an oxygen regulation method for a refrigeration device, comprising the following steps:

[0009] During the operation of the oxygen conditioning module, the temperature of the oxygen conditioning chamber and the temperature of the cooling chamber are continuously monitored.

[0010] The oxygen regulating module is used to regulate the oxygen concentration in the oxygen regulating chamber, the cooling gas supply assembly is used to supply the cooling capacity generated by the refrigeration system to both the oxygen regulating chamber and the cooling chamber simultaneously, the cooling assembly cools the oxygen regulating chamber in the first operating state, an openable and closable damper is provided between the oxygen regulating chamber and the cooling gas supply assembly, and a fan is provided in the cooling gas supply assembly.

[0011] When the temperature of the refrigeration chamber is lower than the high-temperature threshold for refrigeration and the temperature of the oxygen-regulating chamber is higher than the oxygen-regulating temperature threshold, the refrigeration system shuts down and the cooling component switches to the first operating state.

[0012] As a further improvement to the present invention, the following steps are also included:

[0013] When the downtime of the oxygen regulation module exceeds the downtime cycle time, the oxygen regulation module is switched to working state.

[0014] As a further improvement of the present invention, the method further includes the step of: when the downtime of the oxygen regulation module is greater than the downtime cycle time, checking whether the refrigeration system is in a downtime state.

[0015] If the refrigeration system is in a shutdown state, switch the oxygen regulation module to the working state;

[0016] If the refrigeration system is not in a shutdown state, the oxygen regulation module will be switched to the working state after the refrigeration system is shut down.

[0017] As a further improvement of the present invention, the oxygen regulation module is used to adjust the oxygen concentration in the oxygen regulation chamber so that the oxygen concentration in the oxygen regulation chamber is lower than the oxygen concentration in the outside.

[0018] As a further improvement to the present invention, the following steps are also included:

[0019] During the operation of the oxygen regulation module, if the working time of the oxygen regulation module is longer than the working cycle time, the oxygen regulation module will be switched to a shutdown state.

[0020] As a further improvement to the present invention, the following steps are also included:

[0021] When the temperature of the refrigeration chamber is higher than the high temperature threshold for refrigeration and the temperature of the oxygen conditioning chamber is higher than the oxygen conditioning temperature threshold, the refrigeration system is started and the cooling components are switched to the first operating state.

[0022] As a further improvement of the present invention, the cooling assembly includes a cooling air path, a first fan and a first damper. In the first operating state, the first fan is running and the first damper is open. The cooling air supplied by the cooling air path to the oxygen conditioning room flows only outside the oxygen conditioning room.

[0023] The oxygen regulation method also includes the following steps:

[0024] When the temperature of the refrigeration chamber is lower than the high-temperature threshold for refrigeration and the temperature of the oxygen-regulating chamber is lower than the oxygen-regulating temperature threshold, the refrigeration system shuts down, the first fan stops, and the first damper closes.

[0025] As a further improvement of the present invention, the oxygen-regulating chamber contains a drawer, and a moisture-permeable module is provided above the opening of the drawer to adjust the humidity difference between the oxygen-regulating chamber and the cooling chamber.

[0026] To achieve one of the above-mentioned objectives, an embodiment of the present invention provides a refrigeration device, comprising:

[0027] The cooling component air path includes a cooling air path, a first fan and a first damper. When the cooling component is in the first operating state, it cools the oxygen conditioning chamber (10).

[0029] The oxygen conditioning room and the refrigeration room are both connected to the cold air supply circuit for refrigeration.

[0030] An oxygen regulation module is used to adjust the oxygen concentration in the oxygen regulation chamber.

[0031] Storage module, used to store computer programs;

[0032] The processing module, when executing the computer program, can implement the steps in the oxygen regulation method of the refrigeration equipment described above.

[0033] To achieve one of the above-mentioned objectives, one embodiment of the present invention provides a readable storage medium storing a computer program that, when executed by a processing module, can implement the steps in the oxygen regulation method of the refrigeration device described above.

[0034] Compared with the prior art, the present invention has the following beneficial effects: The oxygen regulation method of the refrigeration equipment can achieve precise cooling of the oxygen regulation room by utilizing the existing cooling capacity without further cooling of the refrigeration room. This can avoid the risk of excessively low temperatures in the refrigeration room and the oxygen regulation room, while effectively reducing the temperature of the oxygen regulation room. This ensures that the food is kept fresh in a suitable low-oxygen and suitable-temperature environment, improves the refrigeration efficiency of the equipment, enhances the intelligence level of the refrigeration equipment, and ensures that the temperature is controlled within a suitable range while maintaining a suitable oxygen concentration.

Detailed Implementation

[0043] The present invention 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 invention, 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 the present invention.

[0044] One embodiment of the present invention provides a refrigeration device and its oxygen regulation method that can ensure the preservation of food in a suitable oxygen concentration and temperature environment.

[0045] The refrigeration equipment in this embodiment can be a refrigerator, freezer, upright refrigerator, wine cabinet, etc. The following embodiment will use a refrigerator as an example for explanation. The overall structure of the refrigerator is as follows: Figure 1 As shown.

[0046] The refrigerator includes a refrigeration system, a refrigeration compartment 60, an oxygen-regulating compartment 10, an oxygen-regulating module, and a cooling supply component. The refrigeration system includes a compressor, a condenser, a capillary tube, an evaporator, and refrigeration pipes. The evaporator can be located in the evaporator chamber, and there can be one or more evaporators. For example, for a refrigerator with separate refrigeration compartments and freezer compartments, separate refrigeration evaporators and freezer evaporators are provided.

[0047] The cooling system includes a cooling air supply path, a first fan, and a first damper. When the first fan operates and the first damper opens, the cooling air supplied to the oxygen-regulating chamber 10 flows only outside the oxygen-regulating chamber 10. Alternatively, the cooling system may also include a second fan and a second damper, wherein the first fan corresponds to the oxygen-regulating chamber 10, and the second fan corresponds to the cooling chamber 60. Alternatively, when the first and second dampers are open, the first fan can simultaneously cool both the oxygen-regulating chamber 10 and the cooling chamber 60. The following explanation uses the example of a single fan simultaneously supplying cooling to both the oxygen-regulating chamber 10 and the cooling chamber 60.

[0048] Furthermore, the first operating state of the cooling component, as distinguished below, is a state in which the first fan is running, the first damper is open, and the cooling air supplied to the oxygen-regulating chamber 10 by the cooling air circuit flows only outside the oxygen-regulating chamber 10. At this time, the second damper can be closed. The cooling component can also have a second, third, and fourth operating states. In the second operating state, the first fan is running, the first damper is closed, and the second damper is open. In the third operating state, the first fan is running, the first damper is open, and the second damper is open. In the fourth operating state, the first fan is closed, the first damper is closed, and the second damper is closed.

[0049] Cold air can be blown into the interior of the cooling room 60, or into or out of the oxygen conditioning room 10. In this embodiment, the cold air flows only on the outside of the oxygen conditioning room 10, and the cooling capacity is indirectly transmitted into the interior of the oxygen conditioning room 10 through the outer wall of the oxygen conditioning room 10.

[0050] The cooling air supply circuit connects the refrigeration compartment 60 and the refrigeration system. When the second damper is open, the first fan and / or the second fan can blow the cooling energy from the evaporator in the evaporator chamber into the refrigeration compartment 60. The refrigeration compartment 60 can be a refrigerator compartment, a freezer compartment, a variable temperature compartment, etc. The refrigeration compartment 60 described below uses a refrigerator compartment as an example. A portion of the refrigeration system is installed within the cooling air supply circuit, which includes, for example, air ducts and the evaporator chamber.

[0051] As described in the background section, the oxygen-regulating chamber 10 is a dedicated compartment for preserving fresh ingredients. Its internal oxygen concentration is adjustable, and an oxygen-regulating module is used to adjust the oxygen concentration within the chamber. Based on the characteristics of the stored ingredients, different oxygen concentrations are adjusted to maintain the ingredients in their optimal storage condition. A first, closable damper is installed between the outer side of the oxygen-regulating chamber 10 and the cooling air supply path. When the first damper is open and the first fan operates, it blows the cooling energy from the cooling air supply path, especially from the evaporator, towards the outer side of the oxygen-regulating chamber 10. The first damper can be connected to a motor; the motor rotates the damper to open and close it. When the first damper is open, the cooling air supply path is connected to the oxygen-regulating chamber 10; when closed, it isolates the cooling air supply path from the oxygen-regulating chamber 10. A second damper also employs the same structure as the first damper.

[0052] The humidity and / or oxygen concentration in the oxygen-controlled chamber 10 are adjustable. The oxygen-controlled chamber 10 includes a cavity with an opening. A drawer 20 is housed in the cavity through the opening. The drawer 20 includes an open opening. Users can pull out the drawer 20 through the opening and take food into the drawer 20 through the open opening.

[0053] To clearly express the positions and directions described in this embodiment, in this embodiment, the direction of gravity is defined as up and down, that is, the direction of gravity is down and the opposite direction is up. When the user operates the items inside the refrigerator, the user is defined as standing in front of the refrigerator, and the opposite direction is behind. The two sides of the plane containing the front, back, up, and down are the left and right sides, respectively. Correspondingly, the opening is located in front of the oxygen-regulating chamber 10, and the open opening is located above the drawer 20. The drawer 20 can be pushed and pulled in the front-back direction.

[0054] The oxygen conditioning module can supply gas to the oxygen conditioning chamber 10 from below. A moisture permeable module 40 is provided above the opening of the drawer 20 to adjust the humidity difference between the oxygen conditioning chamber 10 and the refrigeration chamber 60.

[0055] The following is combined Figures 2-3 This invention describes an oxygen regulation method for a refrigeration device 100 provided in an embodiment of the present invention. Although the present application provides method operation steps as shown in the following embodiments or flowcharts, the execution order of these steps is not limited to the execution order provided in the embodiments of the present application, based on conventional or non-creative labor, where there is no necessary causal relationship in the logically consistent steps of the method.

[0056] Specifically, such as Figure 2 As shown, the oxygen regulation method of the refrigeration equipment 100 includes the following steps:

[0057] Step S20: During the operation of the oxygen conditioning module, continuously monitor the temperature of the oxygen conditioning chamber 10 and the temperature of the cooling chamber 60.

[0058] Step S41: Determine whether the temperature Tr of the refrigeration chamber 60 is lower than the high temperature threshold Tr' of refrigeration, and whether the temperature Tt of the oxygen conditioning chamber 10 is higher than the oxygen conditioning temperature threshold Tt'.

[0059] Step S51: If both are true, the refrigeration system stops and the cooling component switches to the first operating state.

[0060] As described in the background art, if the effects of oxygen regulation and refrigeration are not considered as a whole, and the entire refrigeration chamber 60 and the oxygen regulation chamber 10 are refrigerated only through the refrigeration system, when the temperature of the refrigeration chamber 60 is already lower than the set value, further refrigerating the refrigeration chamber 60 in order to refrigerate the oxygen regulation chamber 10 will result in an excessively low storage environment temperature, affecting the preservation effect.

[0061] In this embodiment, the coordination of the operation of the refrigeration system, the operation of the first fan, and the opening and closing of the first damper allows the oxygen-regulating chamber 10 to utilize the existing cooling capacity of the evaporator for cooling when the refrigeration chamber 60 does not require refrigeration, thus preventing the refrigeration chamber 60 from being over-cooled. Specifically, assuming a high-temperature threshold of 4°C for refrigeration and a temperature threshold of 1°C for oxygen regulation, when the temperature of the refrigeration chamber 60 is lower than the high-temperature threshold, for example, 3°C, the refrigeration system stops, and the temperature of the refrigeration evaporator may be between -20°C and -30°C. At this time, the temperature of the oxygen-regulating chamber 10 is also 3°C. Through step S51, without operating the refrigeration system (i.e., when the compressor is not working), the oxygen-regulating chamber 10 is cooled using the existing cooling capacity of the evaporator. This prevents the temperature of the refrigeration chamber 60 from becoming too low and also lowers the temperature of the oxygen-regulating chamber 10 to a suitable level, avoiding a decrease in the preservation effect caused by an excessively high temperature in the oxygen-regulating chamber 10 and preventing food from freezing due to an excessively low temperature in the refrigeration chamber 60.

[0062] Furthermore, this method reduces the frequency of switching the refrigeration system on and off, improving the energy efficiency of the equipment. This solution enhances the intelligence level of the refrigeration equipment 100, ensuring that while maintaining a suitable oxygen concentration, the temperature is also controlled within a suitable range.

[0063] In addition, the refrigeration compartment 60 can be a cold storage compartment, and the oxygen-conditioning compartment 10 contains drawers 20. That is to say, the volume of the refrigeration compartment 60 is much larger than the volume of the oxygen-conditioning compartment 10. Therefore, when the refrigeration system has been shut down, the existing cooling capacity of the evaporator can maintain a dynamic balance between the cooling of the cold storage compartment and the natural heating of the cold storage compartment itself for a certain period of time. When the refrigeration system is shut down, the temperature of the refrigeration compartment 60 will not drop too much, and the remaining cooling capacity of the refrigeration system is sufficient to lower the temperature of the oxygen-conditioning compartment 10.

[0064] Furthermore, such as Figure 3 As shown, the oxygen regulation method also includes the following steps:

[0065] Step S10: When the downtime of the oxygen regulation module is greater than the downtime cycle time, switch the oxygen regulation module to the working state.

[0066] The oxygen adjustment module operates in a periodic manner, with a working cycle time t1 and a shutdown cycle time t2. That is to say, the oxygen adjustment module can be shut down after working for time t1, and then restarted after shutdown for time t2, and so on.

[0067] Step S10 is when the downtime exceeds t2, the system returns to the working state. That is, when the downtime of the oxygen adjustment module exceeds the set cycle time, the system will automatically switch the oxygen adjustment module to the working state, which can effectively avoid the situation where the oxygen concentration is out of control due to the oxygen adjustment module being shut down for too long.

[0068] Through proper time management and automatic control, this oxygen regulation module can maintain a continuous and stable oxygen concentration environment without manual intervention. For food items requiring long-term storage, it can maintain their freshness over a longer storage period, preventing spoilage due to changes in oxygen concentration. Furthermore, the automated adjustment not only improves system efficiency, as the oxygen regulation module only activates when necessary, avoiding unnecessary energy consumption.

[0069] In addition, the work cycle time t1 and the downtime cycle time t2 can be a guarantee period, meaning that the arrival of the downtime cycle time t2 does not mean that work will start immediately. For example, the following steps can be performed:

[0070] When the downtime of the oxygen control module is longer than the downtime cycle time, check whether the refrigeration system is in a shutdown state.

[0071] If the refrigeration system is in a shutdown state, switch the oxygen regulation module to the working state;

[0072] If the refrigeration system is not in a shutdown state, the oxygen regulation module will be switched to the working state after the refrigeration system is shut down.

[0073] If the refrigeration system is operating, the oxygen regulating module is not activated immediately. Instead, it is activated only after the refrigeration system has shut down. This avoids refrigeration conflicts that can occur when the oxygen regulating module is running simultaneously during the refrigeration process. For example, if the temperature of the oxygen regulating gas is too low or too high, and its temperature differs from the external cooling capacity of the oxygen regulating chamber 10, the temperature inside the drawer 20 may be difficult to control accurately, making it hard to judge. Therefore, the oxygen regulating module is switched to operating mode only after the refrigeration system has shut down. This phased and rationally arranged operating mode allows the system to effectively and accurately control the temperature, avoid excessive energy consumption, and improve energy efficiency.

[0074] Furthermore, the oxygen-regulating module and refrigeration system can operate at different times, ensuring that they do not interfere with each other and avoiding the superposition of noise from both types of equipment, thus reducing the maximum noise emitted by the refrigeration equipment. Each module also operates independently, avoiding resonance and improving the overall balance and stability of the system. Ultimately, this ensures that the operation of both the oxygen-regulating module and the refrigeration system can more accurately meet the preservation requirements.

[0075] The oxygen regulation module is used to adjust the oxygen concentration in the oxygen regulation chamber 10 so that the oxygen concentration in the oxygen regulation chamber 10 is lower than the oxygen concentration in the outside.

[0076] By precisely controlling oxygen concentration, a stable low-oxygen environment can be provided for stored food, inhibiting respiration and extending shelf life. The benefits of a low-oxygen environment include a significant reduction in oxidation rates and microbial growth, particularly for perishable fruits and vegetables, where the preservation effect is especially pronounced. Because this solution precisely controls oxygen concentration, it avoids the instability in food quality caused by large fluctuations in oxygen concentration in traditional equipment, thus ensuring long-term preservation.

[0077] The oxygen concentration in the outside atmosphere is generally around 21%, while the oxygen concentration in oxygen-regulating chamber 10 can be reduced to the range of 17% to 20%.

[0078] In addition, if some ingredients require a high-oxygen environment, the oxygen regulation module can also be used to adjust the oxygen concentration in the oxygen regulation chamber 10 so that the oxygen concentration in the oxygen regulation chamber 10 is higher than the oxygen concentration in the outside, for example, so that the oxygen concentration in the oxygen regulation chamber 10 reaches the range of 22% to 25%.

[0079] Furthermore, such as Figure 3 As shown, the oxygen regulation method also includes the following steps:

[0080] Step S30: During the operation of the oxygen regulation module, when the working time of the oxygen regulation module is greater than the working cycle time, the oxygen regulation module is switched to the shutdown state.

[0081] By setting an upper limit for the working time of the oxygen regulating module, it can automatically shut down when the oxygen concentration reaches the expected target, avoiding abnormal oxygen concentration, effectively reducing energy waste, improving the energy efficiency of the equipment, and also reducing mechanical wear and extending its service life. Furthermore, the automatic shutdown function avoids the potential for system overheating or efficiency degradation that may result from prolonged continuous operation of the oxygen regulating module, thus enabling the system to maintain efficient and stable operation for an extended period.

[0082] Continue as Figure 3 As shown, the oxygen regulation method also includes the following steps:

[0083] Step S42: Determine whether the temperature of the refrigeration chamber 60 is higher than the refrigeration high temperature threshold Tr' and whether the temperature Tt of the oxygen conditioning chamber 10 is higher than the oxygen conditioning temperature threshold Tt';

[0084] Step S52: If both are true, the refrigeration system is started, the first fan runs, and the first damper is opened.

[0085] When the temperature in the cooling compartment 60 and the oxygen-regulating compartment 10 is too high, the refrigerator temperature becomes excessive. The system automatically activates cooling, simultaneously turning on the first fan and the first damper to allow cold air to enter the oxygen-regulating compartment 10, thereby lowering the temperature of both compartments. This system responds quickly and effectively to high temperatures, preventing a decrease in food preservation due to excessive heat.

[0086] Continue as Figure 3 As shown, the oxygen regulation method also includes the following steps:

[0087] Step S43: Determine whether the temperature Tr of the refrigeration chamber 60 is lower than the refrigeration high temperature threshold Tr' and whether the temperature Tt of the oxygen conditioning chamber 10 is lower than the oxygen conditioning temperature threshold Tt';

[0088] Step S53: If both are true, the refrigeration system stops, the first fan stops, and the first damper closes.

[0089] When the temperature in the refrigeration chamber 60 falls below the set value, and the temperature in the oxygen-regulating chamber 10 is also low, the system will shut down and close the first fan and the first damper, ceasing cooling of both the oxygen-regulating chamber 10 and the refrigeration chamber 60 to prevent further temperature drops. This reasonable shutdown mechanism prevents the refrigeration chamber 60 and the oxygen-regulating chamber 10 from becoming too cold due to continuous cooling, thus avoiding damage to food due to low temperatures. Furthermore, it effectively reduces unnecessary system operation time, decreases energy consumption, and extends the equipment's lifespan.

[0090] like Figures 4-7 As shown, the oxygen conditioning chamber 10 includes a first air inlet and a first air return port, the drawer 20 includes a second air inlet 21 and a second air return port 22, and the oxygen conditioning module includes an air outlet 31 and a third air return port 32. The air outlet 31 supplies air to the first air inlet and passes through the second air inlet 21, the second air return port 22, and the first air return port in sequence before returning to the third air return port 32. Figure 6In this design, both the air outlet 31 and the third return air outlet 32 ​​face the bottom wall of the oxygen-regulating chamber 10. The closed-loop circulation of the second air inlet 21 and the return air outlet within the drawer 20 ensures that oxygen is evenly distributed within the oxygen-regulating chamber 10. This multi-stage airflow circulation design avoids uneven oxygen concentration in localized areas, especially when storing large or complex-shaped food items, ensuring consistent oxygen concentration throughout the drawer 20 and extending the shelf life of the food. The entire airflow circulation path design not only ensures continuous oxygen regulation but also improves the energy efficiency of the equipment and reduces energy waste through a reasonable airflow layout.

[0091] In addition, the oxygen control module includes at least one anode and at least one cathode, with the anode being controllably connected to the positive terminal of the power supply and the cathode being controllably connected to the negative terminal of the power supply.

[0092] Thus, when the controller controls the oxygen regulating module to run, under the control of the controller, the positive terminal of the power supply is connected to the anode and the negative terminal of the power supply is connected to the cathode, that is, the power supply supplies power to the oxygen regulating module; and when the controller controls the oxygen regulating module to stop, under the control of the controller, the positive terminal of the power supply is connected to the anode and the negative terminal of the power supply is connected to the cathode, that is, the power supply stops supplying power to the oxygen regulating module.

[0093] The oxygen control module also includes an inner cavity that can at least contain the electrolyte, with a first side of the cathode exposed in the inner cavity and a second side exposed to the external air of the oxygen control module.

[0094] When the oxygen regulating module is running, i.e., when it is energized, the cathode is used to consume oxygen from the outside air through an electrochemical reaction. Specifically, oxygen undergoes a reduction reaction at the cathode, with the reaction formula being O2 + 2H2O + 4e-. - →4OH - In this way, an oxygen-deficient preservation atmosphere can be formed outside the oxygen-regulating module.

[0095] One or both sides of the anode are exposed in the inner cavity. The anode is used to generate oxygen in the inner cavity through an electrochemical reaction to create an oxygen-rich preservation atmosphere. Specifically, OH- in the electrolyte... - An oxidation reaction can occur at the anode to produce oxygen, with the reaction formula being 4OH⁻. - →O2 + 2H2O + 4e - The generated oxygen is collected to create an oxygen-rich preservation atmosphere.

[0096] This allows you to adjust the oxygen concentration as needed and choose a suitable oxygen-deficient or oxygen-enriched preservation atmosphere.

[0097] Compared with the prior art, this embodiment has the following beneficial effects:

[0098] The oxygen regulation method of this refrigeration equipment can precisely cool the oxygen-regulating room using existing cooling capacity without further cooling of the refrigeration room. This avoids the risk of excessively low temperatures in both the refrigeration and oxygen-regulating rooms, while effectively reducing the temperature of the oxygen-regulating room. This ensures that food is kept fresh in a suitable low-oxygen, suitable-temperature environment, improves the refrigeration efficiency of the equipment, enhances the intelligence level of the refrigeration equipment, and ensures that the temperature is controlled within a suitable range while maintaining a suitable oxygen concentration.

[0099] The refrigeration equipment may also include, but is not limited to, a processing module, a storage module, and a computer program stored in the storage module and executable on the processing module, such as the oxygen regulation method program for the refrigeration equipment described above. When the processing module executes the computer program, it implements the steps in the oxygen regulation method embodiments of the various refrigeration equipment described above, for example... Figure 2 and 3 The steps are shown.

[0100] The humidity sensor of the refrigeration equipment is used to continuously monitor the temperature of the oxygen conditioning chamber 10 and the temperature of the refrigeration chamber 60 during the operation of the oxygen conditioning module. The oxygen conditioning module is used to adjust the oxygen concentration of the oxygen conditioning chamber 10, and the cooling component is used to supply the cooling capacity generated by the refrigeration system to the oxygen conditioning chamber 10 and the refrigeration chamber 60. The cooling component cools the oxygen conditioning chamber 10 in the first operating state.

[0101] The processing module is used to control the refrigeration system to shut down and switch the cooling component to the first operating state when the temperature of the refrigeration chamber 60 is lower than the refrigeration high temperature threshold and the temperature of the oxygen conditioning chamber 10 is higher than the oxygen conditioning temperature threshold.

[0102] The processing module can be a Central Processing Unit (CPU), or other general-purpose processors, Digital Signal Processors (DSPs), Application Specific Integrated Circuits (ASICs), Field-Programmable Gate Arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. General-purpose processors can be microprocessors or any conventional processor. The processing module is the control center of the refrigeration equipment, connecting all parts of the equipment via various interfaces and lines.

[0103] The storage module can be used to store the computer programs and / or modules. The processing module implements various functions of the refrigeration equipment by running or executing the computer programs and / or modules stored in the storage module and by calling the data stored in the storage module. The storage module may mainly include a program storage area and a data storage area. The program storage area may store the operating system, at least one application program required for a function, etc. In addition, the storage module may include high-speed random access memory, and may also include non-volatile memory, such as hard disk, RAM, plug-in hard disk, smart media card (SMC), secure digital (SD) card, flash card, at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0104] For example, the computer program can be divided into one or more modules / units, which are stored in a storage module and executed by a processing module to complete the present invention.
