Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oxygen production structure, in particular to an oxygen production structure, an air conditioner, a control method, a device and a medium. BACKGROUND

[0002] At present, the oxygen production air conditioner mainly separates oxygen and other gases in the air through a molecular sieve to produce high-purity oxygen. The molecular sieve is a kind of porous material with selective adsorption capacity, which can separate according to the size of gas molecules. However, when water enters the molecular sieve, the water will enter the pores of the molecular sieve and destroy the physical structure of the molecular sieve, causing the pores to be blocked or deformed, thereby affecting its adsorption performance. At the same time, water itself is a substance that can be adsorbed by the molecular sieve, if there is water in the molecular sieve, it may preferentially adsorb water molecules, thereby reducing the adsorption amount of oxygen and other target gases, resulting in reduced oxygen production efficiency, therefore, the existing technology usually needs to use a drying device to dry the gas entering the molecular sieve.

[0003] However, the hygroscopic material in the drying device will reach adsorption saturation after a long time of use, and needs to be regenerated by heating to restore its hygroscopic capacity. During the regeneration process, the heated hygroscopic material releases water vapor, if this part of water vapor cannot be effectively discharged, it may recondense, not only affecting the hygroscopic effect of the drying device, but also polluting the molecular sieve in the oxygen production tower, reducing the oxygen production capacity and operating efficiency of the entire system.

[0064] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0065] like Figures 1 to 7 As shown, one embodiment of the present invention provides an oxygen production structure, which includes an oxygen production section 1, a drying section 2, and a guide section 3. The oxygen production section 1 is used to separate oxygen from the air and has an oxygen production inlet for admitting air. The drying section 2 has a drying chamber 21 for accommodating a hygroscopic material 22, and an air inlet and an air outlet connected to the drying chamber 21. The air inlet is used to admit air. The guide section 3 has a guide inlet 31, a first outlet 32, and a second outlet 33. The guide inlet 31 is selectively connected to the air outlet. The first outlet 32 ​​is used to discharge water vapor and is connected to the oxygen production inlet. The first outlet 32 ​​and the second outlet 33 are both selectively connected to the guide inlet 31.

[0066] The oxygen production structure provided by the embodiment of the present application can significantly reduce the moisture in the air by pre-drying the air entering the oxygen production part 1 through the drying part 2, prevent the moisture from adversely affecting the performance of the molecular sieve in the oxygen production part 1, thereby improving the oxygen production efficiency and the purity of the produced oxygen. The hygroscopic material 22 in the drying part 2 can reach adsorption saturation after long-term use, and in the process of regenerating and recovering the hygroscopic material 22, the adsorbed water vapor in the hygroscopic material 22 can be released. The setting of the guiding part 3 can flexibly adjust the air flow direction according to the regeneration needs of the drying part 2. In the normal oxygen production mode, the second outlet 33 of the guiding part 3 is connected with the oxygen production inlet of the oxygen production part 1, ensuring the stable supply of dry air. In the regeneration process, the guiding inlet 31 can be connected with the first outlet 32, thereby discharging the water vapor generated in the drying process, avoiding the water vapor remaining in the drying part 2 and entering the oxygen production part 1 in the subsequent oxygen production process, and enhancing the overall stability of the oxygen production structure. The guiding part 3 can adjust the connection state of the guiding inlet 31, the first outlet 32 and the second outlet 33 according to different operating conditions and needs. Whether it is the supply of dry air or the discharge of water vapor, it can be efficiently completed under the unified control of the guiding part 3, enhancing the adaptability to different operating environments and the flexibility of operation. Therefore, through the oxygen production structure provided by the embodiment, the problem that the water vapor formed in the regeneration process of the drying device of the oxygen production structure in the prior art cannot be effectively discharged can be solved.

[0067] It should be noted that the guiding inlet 31 being selectively connected with the air outlet means that the guiding inlet 31 can be connected with the air outlet or isolated from the air outlet. The first outlet 32 and the second outlet 33 are selectively connected with the guiding inlet 31, which means that the first outlet 32 can be connected with the guiding inlet 31 or isolated from the guiding inlet 31, and the second outlet 33 can be connected with the guiding inlet 31 or isolated from the guiding inlet 31.

[0068] Specifically, the oxygen production part 1 has an oxygen outlet and a nitrogen discharge port 11. The oxygen outlet is used to discharge the separated oxygen, and the nitrogen discharge port 11 is used to discharge the separated nitrogen. The oxygen outlet is provided with an oxygen outlet pipe 12, which is used to communicate with the to-be-connected equipment to supply oxygen to the to-be-connected equipment.

[0069] Specifically, the hygroscopic material 22 includes silica gel, activated alumina, mineral desiccant and other materials that can be used to adsorb moisture in the air.

[0070] Specifically, the oxygen production structure further comprises a heating portion 4 arranged below the drying portion 2 and configured to perform a heating treatment on the drying cavity 21 to evaporate the moisture adsorbed in the moisture-absorbing material 22 in the drying cavity 21. With such a structure, the heating portion 4 directly heats the moisture-absorbing material 22 in the drying cavity 21, which can effectively improve the regeneration efficiency of the moisture-absorbing material 22. Through heating, the moisture adsorbed in the moisture-absorbing material 22 is rapidly converted into water vapor and discharged, restoring its moisture-absorbing performance and ensuring the dryness of the air in the oxygen production process. Moreover, the heating portion 4 is arranged below the drying portion 2, which can utilize the natural convection principle of hot air rising to make the temperature distribution in the drying cavity 21 more uniform, avoiding damage to the moisture-absorbing material 22 or incomplete regeneration caused by uneven heating. The lower heating design can make full use of the heat generated by the heating portion 4, reduce heat waste, and more efficiently transfer heat directly to the moisture-absorbing material 22 compared to top or peripheral heating, thereby reducing the overall energy consumption of the system. At the same time, by heating from below, the accumulation of condensed water at the top of the drying cavity 21 due to temperature difference can be effectively avoided, reducing the possibility of re-adsorption of condensed water on the moisture-absorbing material 22, maintaining the dry state of the moisture-absorbing material 22, and further improving its regeneration efficiency and the stability of the oxygen production system.

[0071] Specifically, the heating portion 4 comprises an electric heating wire, an electric heating sheet, an infrared heater, or other structures that can be used to heat the moisture-absorbing material 22.

[0072] In an embodiment, the guiding portion 3 has a guiding cavity 34, and the guiding inlet 31, the first outlet 32, and the second outlet 33 are all connected to the guiding cavity 34. The guiding portion 3 comprises a sliding block 35 movably arranged in the guiding cavity 34 to move to an oxygen production position in which the sliding block 35 blocks the first outlet 32 and avoids the guiding inlet 31 and the second outlet 33, a water vapor discharge position in which the sliding block 35 blocks the second outlet 33 and avoids the guiding inlet 31 and the first outlet 32, or a heat preservation position in which the sliding block 35 blocks the guiding inlet 31. With such a structure, the path of the air entering from the guiding inlet 31 to the second outlet 33 (oxygen production position) or the first outlet 32 (water vapor discharge position) can be accurately controlled by the movement of the sliding block 35 in the guiding cavity 34, and the guiding inlet 31 can be blocked (heat preservation position) under certain conditions, ensuring the accuracy and controllability of the air flow in different operating modes of the system. The dynamic blocking and avoiding of the sliding block 35 avoids the entry of moisture into the oxygen production portion 1 during oxygen production, reducing the energy consumption during oxygen production; in the water vapor discharge position, the water vapor can be effectively guided to discharge, avoiding pollution and damage to other components in the system; in the heat preservation position, the guiding inlet 31 is blocked, reducing heat loss and improving the efficiency of the heating and regeneration process.

[0073] Specifically, the guide part 3 is a three-way valve structure. The guide inlet 31 is arranged at one side of the guide cavity 34, the first outlet 32 and the second outlet 33 are both arranged at the other side of the guide cavity 34, the first outlet 32 and the second outlet 33 are arranged in a spaced manner, the first outlet 32 and the second outlet 33 are arranged in a staggered manner with the guide inlet 31, and the sliding block 35 is movably arranged in the direction from the first outlet 32 to the second outlet 33. In this way, through the flexible movement of the sliding block 35, the guidance of the air between the oxygen production position, the water vapor discharge position and the heat preservation position can be accurately controlled, and it is ensured that the dry air is directly supplied to the oxygen production part 1 in the oxygen production process, the water is effectively discharged through the first outlet 32 in the regeneration process, and the air passage is timely blocked in the heat preservation stage, which reduces the invalid air circulation and improves the operation efficiency of the system.

[0074] Specifically, as shown in Figure 5 the sliding block 35 is in the oxygen production position, the guide inlet 31 is communicated with the second outlet 33 through the guide cavity 34, so that the air is introduced into the oxygen production inlet. As shown in Figure 6 the sliding block 35 is in the water vapor discharge position, the guide inlet 31 is communicated with the first outlet 32 through the guide cavity 34, so that the air with water vapor is discharged from the first outlet 32. As shown in Figure 7 the sliding block 35 is in the heat preservation position, the sliding block 35 blocks at the guide inlet 31, so that the first outlet 32 and the second outlet 33 are both isolated from the guide inlet 31, so that the air stays in the drying part 2 and can be fully heated.

[0075] Specifically, the guide part 3 is an electromagnetic three-way valve structure. The electromagnetic driving characteristic of the electromagnetic three-way valve makes its response speed extremely fast, and it can instantaneously switch between different working modes, thereby improving the working efficiency of the entire air conditioning oxygen production system and reducing the energy waste in the transition time.

[0076] In an embodiment, the oxygen production structure further comprises an air inlet pipeline 5 and an air outlet pipeline 6. One end of the air inlet pipeline 5 is used for introducing air, and the other end of the air inlet pipeline 5 is communicated with the air inlet. One end of the air outlet pipeline 6 is communicated with the air outlet, and the other end of the air outlet pipeline 6 is communicated with the guide inlet 31. The air inlet pipeline 5 and the air outlet pipeline 6 are both arranged at the side of the drying part 2, the extension direction of the air inlet pipeline 5 and the extension direction of the air outlet pipeline 6 are arranged at a preset angle, and the preset angle is greater than 0° and less than 180°. By arranging the air inlet pipeline 5 and the air outlet pipeline 6 at the side of the drying part 2 and arranging the extension directions of the two pipelines at a preset angle, the airflow path can be effectively optimized, the flow distance and the number of turns of the gas in the structure are reduced, the flow resistance of the air in the pipeline is reduced, direct collision of the airflow is avoided, the air can smoothly enter and leave the drying cavity 21, and the drying efficiency is improved.

[0077] Specifically, the preset angle is 90°. With such a structural arrangement, the internal space of the device can be fully utilized, making the oxygen production structure more compact, which helps to reduce the overall volume of the device, while providing more flexibility and space for the installation of other components. Moreover, by arranging the two pipes in different directions, the transmission of vibrations caused by pressure of the transmitted gas can be reduced, avoiding mechanical stress and fatigue damage caused by vibrations, and prolonging the service life of the device.

[0078] In an embodiment, the oxygen production part 1 also has an oxygen outlet for discharging oxygen; the oxygen production structure further includes a control member connected to the heating part 4; the oxygen production structure further includes a gas pressure detection member, the detection end of which is arranged on the air inlet pipe 5 to detect the gas pressure of the air entering the air inlet; the gas pressure detection member is connected to the control member, and the control member is used to control the heating part 4 to be in a heating state or a non-heating state according to the detection result of the gas pressure detection member. With such a structural arrangement, the setting of the gas pressure detection member can monitor the gas pressure in the air inlet pipe 5 in real time. When an abnormal gas pressure is detected, it indicates that the hygroscopic material 22 in the drying part 2 may reach a saturation state. At this time, the heating part 4 is adjusted into a heating state by the control member, so as to promote the evaporation of moisture in the hygroscopic material 22 and restore its hygroscopic performance, ensuring that the oxygen production process is not affected.

[0079] Specifically, the oxygen production structure further includes an air compressor 7 for compressing air, and the outlet of the air compressor 7 is in communication with the air inlet. The oxygen production structure further includes an air compressor air inlet pipe 71 and an air compressor exhaust pipe 72, the air compressor air inlet pipe 71 being in communication with the air compressor 7 to supply air to the air compressor 7, and the other end of the air compressor exhaust pipe 72 being in communication with the air inlet of the drying part 2. In this way, the air compressor 7 provides a necessary source of high-pressure air for the oxygen production process by compressing air.

[0080] Specifically, the detection end of the gas pressure detection member is arranged at the outlet of the air compressor 7. The outlet of the air compressor 7 is in communication with the air inlet of the drying part 2 through the air inlet pipe 5. In this way, by directly arranging the detection end of the gas pressure detection member at the outlet of the air compressor 7, the pressure information of the compressed air can be obtained in time, providing the most direct data source for the control of the oxygen production structure. The exhaust pressure of the air compressor 7 obtained by the gas pressure detection member is closely related to the saturation degree of the hygroscopic material 22. By analyzing the trend of the compressed air pressure, it can be inferred whether the hygroscopic material 22 is close to saturation, so as to determine when to start the regeneration program of the heating part 4, thereby improving the operating efficiency and reducing the maintenance cost.

[0081] In an embodiment, the oxygen production part 1 further has an oxygen outlet for discharging oxygen; the oxygen production structure further comprises a control member, the control member being connected with the heating part 4; the oxygen production structure further comprises a flow detection member, a detection end of the flow detection member being arranged at the oxygen outlet to detect the oxygen flow at the oxygen outlet; the flow detection member is connected with the control member, and the control member is used to control the heating part 4 to be in a heating state or a non-heating state according to the detection result of the flow detection member. With such a structure, the flow detection member is arranged, so that the system can monitor the oxygen flow at the oxygen outlet in real time. The oxygen flow reflects the oxygen production efficiency. When the hygroscopic material 22 reaches the saturation state, the adsorption capacity thereof decreases, which will cause the water content of the air entering the oxygen production part 1 to increase, and further affect the oxygen generation efficiency. Therefore, through the arrangement of the flow detection member, it can be determined when to start the heating regeneration, so as to avoid frequent regeneration treatment, reduce energy consumption, and also reduce the replacement cost caused by excessive use of the hygroscopic material 22.

[0082] Specifically, the oxygen production structure further comprises a temperature detection member, a detection end of the temperature detection member being arranged in the drying cavity 21 to detect the temperature in the drying cavity 21.

[0083] As shown in Figure 1 and Figure 2 , an embodiment of the present application provides an air conditioner, which comprises an air conditioner body 8 and the above-mentioned oxygen production structure, and the oxygen production structure is mounted on the air conditioner body 8.

[0084] The air conditioner provided by the embodiment of the present application can significantly reduce the moisture in the air by pre-drying the air entering the oxygen production part 1 through the drying part 2, prevent the moisture from having an adverse effect on the performance of the molecular sieve in the oxygen production part 1, and thus improve the oxygen production efficiency and the purity of the produced oxygen. The hygroscopic material 22 in the drying part 2 can reach adsorption saturation after long-time use, and the adsorbed water vapor in the hygroscopic material 22 can be released during the regeneration and recovery of the hygroscopic material 22. The guide part 3 is arranged to flexibly adjust the air flow direction according to the regeneration needs of the drying part 2. In the normal oxygen production mode, the second outlet 33 of the guide part 3 is connected with the oxygen production inlet of the oxygen production part 1, so as to ensure the stable supply of dry air. In the regeneration process, the guide inlet 31 can be connected with the first outlet 32, so as to discharge the water vapor generated in the drying process, avoid the water vapor remaining in the drying part 2 and entering the oxygen production part 1 in the subsequent oxygen production process, and enhance the overall stability of the oxygen production structure. The guide part 3 can adjust the communication states of the guide inlet 31, the first outlet 32 and the second outlet 33 according to different operating conditions and needs. Whether it is the supply of dry air or the discharge of water vapor, it can be efficiently completed under the unified control of the guide part 3, and the adaptability to different operating environments and the flexibility of operation are enhanced. Therefore, the air conditioner provided by the embodiment can solve the problem that the water vapor generated in the regeneration process of the drying device of the oxygen production structure in the prior art cannot be effectively discharged.

[0085] As shown in Figure 8 and Figure 9 , an embodiment of the present application provides a control method, the control method is suitable for the above-mentioned oxygen production structure, and the control method comprises the following steps: making the oxygen production structure enter a regeneration process; the regeneration process comprises the following steps: acquiring the temperature in the drying cavity 21 of the oxygen production structure; and adjusting the communication states of the guide inlet 31 of the guide part 3 of the oxygen production structure and the air outlet of the drying part 2 of the oxygen production structure, the communication states of the first outlet 32 of the guide part 3 and the guide inlet 31, and the communication states of the second outlet 33 of the guide part 3 and the guide inlet 31 according to the size of the temperature in the drying cavity 21.

[0086] The control method provided by the embodiment of the present application can intelligently adjust the working mode of the guiding part 3 according to the temperature, can control the communication state of the guiding inlet 31, the first outlet 32 and the second outlet 33 according to the temperature in the drying cavity 21, can accurately control each stage of the regeneration process, including heating, moisture removal and heat preservation, and can avoid the performance decline or damage of the moisture absorption material 22 caused by the excessively high or low temperature in the drying part 2, thereby prolonging the service life of the oxygen production structure, reducing the maintenance frequency and cost, ensuring that the moisture absorption material 22 of the drying part 2 works in the best state, reducing the influence of moisture on the oxygen production process, thereby improving the oxygen production and purity, maintaining the stability of the oxygen production efficiency, and improving the user experience. Therefore, the control method provided by the embodiment can solve the problem that the water vapor formed in the regeneration process of the drying device of the oxygen production structure in the prior art cannot be effectively discharged.

[0087] Specifically, the method of adjusting the communication state of the guiding inlet 31 of the guiding part 3 of the oxygen production structure and the air outlet of the drying part 2 of the oxygen production structure, the communication state of the first outlet 32 of the guiding part 3 and the guiding inlet 31, and the communication state of the second outlet 33 of the guiding part 3 and the guiding inlet 31 according to the temperature in the drying cavity 21 includes: when the temperature in the drying cavity 21 is less than a first preset temperature, the guiding inlet 31 is disconnected from the air outlet, the first outlet 32 is disconnected from the guiding inlet 31, and the second outlet 33 is disconnected from the guiding inlet 31; when the temperature in the drying cavity 21 is greater than or equal to the first preset temperature and less than or equal to a second preset temperature, the first outlet 32 is communicated with the guiding inlet 31, the second outlet 33 is disconnected from the guiding inlet 31, and the guiding inlet 31 is communicated with the air outlet; when the temperature in the drying cavity 21 is greater than the second preset temperature, the first outlet 32 is disconnected from the guiding inlet 31, the second outlet 33 is communicated with the guiding inlet 31, and the guiding inlet 31 is communicated with the air outlet. With such a setting, when the temperature is less than the first preset temperature, all the communication with the guiding inlet 31 is cut off, the first outlet 32 is disconnected from the guiding inlet 31, and the second outlet 33 is disconnected from the guiding inlet 31, so that the drying cavity 21 is in a closed heat preservation state, thereby enabling the moisture absorbing material 22 therein to be fully heated, avoiding the loss of temperature. When the temperature is greater than or equal to the first preset temperature and less than or equal to the second preset temperature, it means that the water vapor has begun to be discharged from the moisture absorbing material 22, at this time the communication state of the guiding part 3 is adjusted to the first outlet 32 communicated with the guiding inlet 31, which can promote the evaporation and discharge of moisture, and the guiding inlet 31 communicated with the air outlet can make the air in the drying cavity 21 in a flowing state, thereby better carrying the water vapor and discharging it. When the temperature is greater than the second preset temperature, it means that the regeneration of the moisture absorbing material 22 has been sufficient, at this time the guiding part 3 switches to the second outlet 33 communicated with the guiding inlet 31, and the guiding inlet 31 re-establishes communication with the air outlet, thereby being able to start oxygen production again, ensuring the yield and output efficiency of oxygen.

[0088] Specifically, the first preset temperature is 100°C, and the second preset temperature is 120°C. In this way, by setting 100°C and 120°C as the threshold values for the state adjustment of the guiding part 3, the system can more finely control the regeneration process, ensuring that the moisture absorbing material 22 is regenerated in a suitable temperature range, neither too hot nor too cold, maintaining the best working state. All the communication is closed below 100°C, avoiding starting other processes when the temperature is not sufficient to support effective regeneration, thereby saving energy. The measures taken above 120°C avoid excessive regeneration affecting oxygen production, ensuring the output efficiency of oxygen.

[0089] In an embodiment, the oxygen production structure further comprises a heating unit 4 arranged on the drying unit 2 of the oxygen production structure and configured to perform a heating treatment on the drying cavity 21; before the first outlet 32 is disconnected from the guide inlet 31, the second outlet 33 is connected to the guide inlet 31, and the guide inlet 31 is connected to the air outlet, the control method further comprises: disconnecting the guide inlet 31 from the air outlet, disconnecting the first outlet 32 from the guide inlet 31, and disconnecting the second outlet 33 from the guide inlet 31, and maintaining for a preset time period. With such an arrangement, the drying unit 2 can be kept in a heat preservation state for a preset time period before the oxygen production structure resumes oxygen production, which helps to ensure the sufficiency and completeness of the regeneration of the moisture-absorbing material 22 and ensures that the moisture-absorbing material 22 can recover to an optimal state after regeneration, thereby improving the long-term operation efficiency of the drying unit 2 and the oxygen production quality.

[0090] In an embodiment, the oxygen production structure further comprises a heating unit 4 arranged on the drying unit 2 of the oxygen production structure and configured to perform a heating treatment on the drying cavity 21; before the first outlet 32 is disconnected from the guide inlet 31, the second outlet 33 is connected to the guide inlet 31, and the guide inlet 31 is connected to the air outlet, the control method further comprises: making the oxygen production structure repeat the regeneration process for a preset number of times. With such an arrangement, making the oxygen production structure repeat the regeneration process for a preset number of times can ensure that the moisture-absorbing material 22 is completely regenerated, and even if the initial regeneration fails to completely remove all moisture, the regeneration effect can be further improved through multiple cycles to achieve complete drying.

[0091] In an embodiment, the oxygen production structure further comprises a heating unit 4 arranged on the drying unit 2 of the oxygen production structure and configured to perform a heating treatment on the drying cavity 21; before the first outlet 32 is disconnected from the guide inlet 31, the second outlet 33 is connected to the guide inlet 31, and the guide inlet 31 is connected to the air outlet, the control method further comprises: disconnecting the guide inlet 31 from the air outlet, disconnecting the first outlet 32 from the guide inlet 31, and disconnecting the second outlet 33 from the guide inlet 31, and maintaining for a preset time period, and after maintaining for the preset time period, making the oxygen production structure repeat the regeneration process for a preset number of times. With such an arrangement, in combination with the stay at the heat preservation position and the regeneration process cycle for a preset number of times, the complete regeneration of the moisture-absorbing material 22 can be ensured, thereby improving the regeneration effect of the drying unit 2 and improving the oxygen production efficiency and oxygen production yield of the oxygen production structure.

[0092] Specifically, the preset time period is 30 seconds.

[0093] Specifically, the preset number of times is 3.

[0094] In an embodiment, before the oxygen production structure enters the regeneration process, the control method further comprises: obtaining the inlet air pressure of the gas entering the air inlet of the drying part 2 and the oxygen production of the oxygen production part 1 of the oxygen production structure; and determining whether to enter the regeneration process according to the size of the inlet air pressure and the size of the oxygen production. With such an arrangement, by monitoring the inlet air pressure of the air inlet of the drying part 2 and the oxygen production of the oxygen production part 1, the system can detect potential problem signals such as abnormal air pressure or reduced oxygen production before the performance of the hygroscopic material decreases, so as to timely trigger the regeneration process and avoid sudden decrease in oxygen production efficiency.

[0095] Specifically, the oxygen production structure further comprises an air compressor 7, and the inlet air pressure of the gas entering the air inlet of the drying part 2 can also be the exhaust air pressure at the outlet of the air compressor 7.

[0096] Specifically, the method for determining whether to enter the regeneration process according to the size of the inlet air pressure and the size of the oxygen production comprises: when the inlet air pressure is less than a preset air pressure threshold, making the oxygen production structure produce oxygen; when the inlet air pressure is greater than or equal to the preset air pressure threshold; in the case that the oxygen production is greater than a preset production threshold, making the oxygen production structure produce oxygen; in the case that the oxygen production is less than or equal to the preset production threshold, making the oxygen production structure enter the regeneration process; wherein the preset air pressure threshold is greater than or equal to 0.13 MPa and less than or equal to 0.2 MPa; and the preset production threshold is greater than or equal to 3.7 L / min and less than or equal to 4.3 L / min. With such an arrangement, when the inlet air pressure is lower than the preset air pressure threshold, the system determines that the hygroscopic material 22 of the drying part 2 is in good condition, and directly performs the oxygen production operation, thereby avoiding unnecessary regeneration process, saving energy and maintaining the oxygen production efficiency. When the inlet air pressure reaches or exceeds the preset air pressure threshold, and the oxygen production is lower than the preset production threshold, the system automatically starts the regeneration process, timely restores the performance of the hygroscopic material 22, and ensures that the working efficiency of the oxygen production part 1 is not affected. By monitoring and analyzing the inlet air pressure and the oxygen production, signs of performance decrease of the hygroscopic material 22 can be found in time, so as to perform the regeneration process in advance, avoid the hygroscopic material 22 being in a high humidity condition for a long time, reduce the risk of material aging and equipment damage, and effectively prolong the overall service life of the oxygen production structure.

[0097] Specifically, the preset air pressure threshold is 0.2 MPa, and the preset production threshold is 4.0 L / min.

[0098] As Figure 9As shown, the running logic of the control method includes: after the air conditioner is turned on, the oxygen production mode is started, the exhaust pressure P1 of the air compressor 7 is first detected, and according to the value of P1, the oxygen production Q is further checked. If P1 is less than the preset air pressure threshold P2, it means that the moisture absorbing material 22 has not reached saturation, and the air conditioner continues to produce oxygen. If P1 is greater than or equal to P2, and the oxygen production Q is greater than the preset production threshold Q1, it means that the current oxygen production condition is ideal, and no additional intervention is needed, and the air conditioner can continue to produce oxygen; otherwise, if Q is less than or equal to Q1, it means that the current oxygen production has been affected, and the regeneration program needs to be started at this time. In the regeneration program, the operation of the air compressor 7 is first stopped, then the three-way valve (the guide part 3) is switched to the heat preservation mode position (the heat preservation position), the heater (the heating part 4) is started, and the drying device temperature (the temperature in the drying cavity 21) is raised. When it is detected that the temperature in the drying cavity 21 is less than 100℃, the regeneration program is repeated, so that the three-way valve remains in the heat preservation mode position; when it is detected that the temperature in the drying cavity 21 is greater than or equal to 100℃, but less than or equal to 120℃, the three-way valve is switched to the water vapor discharge mode position (the water vapor discharge position), at this time the air compressor is started, so that the water vapor in the drying device is discharged through the three-way valve position (that is, the first outlet 32); when it is detected that the temperature in the drying cavity 21 is greater than 120℃, the three-way valve position is switched to the heat preservation position, and the heat preservation is 30s, and then the regeneration program is repeated for 3 times to ensure that the drying device moisture absorbing material is regenerated. After the regeneration program is repeated for 3 times, the three-way valve is switched to the oxygen production mode position (the oxygen production position), and the air conditioner continues to produce oxygen.
