[0047] According to another aspect of the present invention, an air conditioner is provided, applicable to the above-described air conditioner control method, the air conditioner comprising:

[0048] The oxygen generating module includes an air compressor and a molecular sieve component, which are connected by a connecting pipeline.

[0049] The oxygen generation module also includes a heat dissipation module, which includes a heat dissipation fan. The heat dissipation fan is positioned opposite the air compressor to dissipate heat from the air compressor.

[0050] Furthermore, the air conditioner also includes an outdoor unit, which includes a first installation space and a second installation space that are interconnected.

The axial flow fan guides part of the airflow in the first installation space and discharges it to the outdoor unit.

[0051] By applying the technical solution of this invention, the system can immediately identify any changes exceeding the normal range by acquiring key actual operating parameters of the oxygen generation module in real time (including exhaust temperature, pipeline pressure, module humidity, and adsorbent change rate) and comparing them with preset parameter thresholds.

Attached Figure Description

[0054] The accompanying drawings, which form part of this application, are used to provide a further understanding of the invention. The illustrative embodiments of the invention and their descriptions are used to explain the invention and do not constitute an undue limitation of the invention. In the drawings:

[0055] Figure 1 A control flowchart of the air conditioner control method according to the present invention is shown. Detailed Implementation

[0056] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0057] As mentioned in the background section, existing air conditioners with oxygen generation functions do not require oxygen generation in all seasons. Therefore, during prolonged periods when the oxygen generation function is not activated, the oxygen generation system may experience physical or chemical environmental changes, such as decreased adsorbent performance, pipe corrosion or deposits, and alterations in internal temperature and pressure parameters. These changes affect the system's oxygen production and purity. Existing technologies typically rely on manual adjustments or simple experience-based adjustments to address these potential changes during downtime, which not only increases operational complexity and cost but may also lead to inaccurate parameter settings and inefficiency. To address these technical problems, the air conditioner control method provided in this application, after the air conditioner starts oxygen generation mode, acquires the actual operating parameters of the oxygen generation module, compares the actual operating parameters with parameter thresholds, adjusts the actual operating parameters or maintains the current operating parameters based on the comparison results, further acquires the actual total oxygen production C, and compares the actual total oxygen production with the total oxygen production threshold C. m The system compares data; based on the comparison results, it continues to adjust the actual operating parameters or terminates the adjustment program. By integrating real-time monitoring devices for key environmental parameters such as temperature, pressure, humidity, and adsorbent performance, the system can automatically analyze changes in the internal environment of the equipment and dynamically adjust the operating parameters of the oxygen generation system by combining historical operating data and optimization algorithms. This method greatly improves the intelligence level of the equipment, reduces reliance on manual adjustments, and enables the system to automatically optimize operation based on real-time environmental conditions, thereby improving operating efficiency and reliability. The parameter adaptive optimization method ensures that the oxygen generation system quickly reaches its optimal operating state after restarting. Even in cases of significant changes in the internal environment due to long-term shutdown, it can effectively improve oxygen production and purity by dynamically adjusting key parameters such as adsorption time, desorption time, and pressure regulation, meeting users' health needs.

[0058] Please refer to Figure 1 This application provides an air conditioner control method applicable to air conditioners with an oxygen generation module. When the air conditioner starts the oxygen generation mode, the air conditioner control method includes:

[0059] Obtain the actual operating parameters of the oxygen generation module. The actual operating parameters include at least: exhaust temperature, pipeline pressure, module humidity, and adsorbent change rate.

[0060] Compare the actual operating parameters with the parameter thresholds;

[0061] Based on the comparison results, adjust the actual operating parameters or maintain the current operating parameters;

[0062] Obtain the actual total amount of oxygen produced, C;

[0063] Compare the actual total amount of oxygen with the total oxygen threshold C. m Compare;

[0064] Based on the comparison results, continue adjusting the actual operating parameters or terminate the adjustment program.

[0065] By acquiring key operational parameters of the oxygen generation module in real time (including exhaust temperature, pipeline pressure, module humidity, and adsorbent change rate) and comparing them with preset parameter thresholds, the system can immediately identify any changes outside the normal range. This real-time monitoring capability ensures that the system can react quickly and take necessary parameter adjustment measures to prevent low oxygen generation efficiency or system failure caused by abnormal parameters.

[0066] Based on parameter adjustments, the system further monitors the actual total amount of oxygen produced (C) and compares it with the set total oxygen threshold (C). m This closed-loop control strategy can promptly detect and correct situations where oxygen production is insufficient or purity is substandard, ensuring that the quality of the output oxygen always meets user needs.

[0067] Specifically, the air conditioner control method also includes: constructing a temperature threshold T. limit Obtain the exhaust temperature T, and compare the exhaust temperature T with the temperature threshold T. limit Compare the results; based on the comparison, control the oxygen generating module to operate at the current exhaust temperature or adjust the exhaust temperature of the oxygen generating module.

[0068] Temperature threshold (T) limit The settings provide a temperature safety boundary for the operation of the oxygen generation module. When the actual exhaust temperature exceeds the preset temperature threshold, the system can promptly identify and take cooling measures to avoid safety hazards caused by high temperatures, such as premature aging of the adsorbent and overheating damage to the equipment, thereby ensuring the safe operation of the equipment.

[0069] Exhaust temperature is a crucial factor affecting oxygen production efficiency and oxygen purity. By monitoring the exhaust temperature in real time and comparing it with a threshold, the system can intelligently adjust the operating temperature of the oxygen production module to ensure it operates within the optimal temperature range. This helps improve oxygen generation efficiency, reduce energy consumption, and maintain high oxygen purity, meeting users' high standards for air quality.

[0070] Based on the comparison results, methods for controlling the oxygen generating module to operate at the current exhaust temperature or adjusting the exhaust temperature of the oxygen generating module include: when the exhaust temperature T is less than the temperature threshold T... limit When the oxygen generation module operates at the current exhaust temperature, the exhaust temperature T is controlled to operate at the current exhaust temperature; when the exhaust temperature T is greater than or equal to the temperature threshold T... limit At that time, adjust the exhaust temperature of the oxygen generating module.

[0071] When the exhaust temperature T reaches or exceeds the temperature threshold T limit At this time, the system will automatically adjust the operating parameters of the oxygen generation module to reduce the exhaust temperature and prevent the equipment from overheating.

[0072] Exhaust temperature is a crucial factor affecting oxygen production and purity. By precisely controlling the exhaust temperature, the oxygen generation system can separate oxygen more efficiently, ensuring that the produced oxygen is both sufficient and pure. Furthermore, consistently high exhaust temperatures accelerate equipment aging and increase maintenance frequency. Timely adjustment of the exhaust temperature can reduce equipment failure rates, thereby lowering the costs of regular inspections and repairs, saving users money.

[0073] Methods for adjusting the exhaust temperature of the oxygen generating module include: reducing the operating power of the air compressor in the oxygen generating module, or increasing the operating power of the air compressor's heat dissipation module.

[0074] By dynamically controlling the operating power of the air compressor or the operating power of the heat dissipation module, the system can accurately adjust the exhaust temperature to a safe and efficient operating range, avoiding the impact of excessively high or low temperatures on the oxygen production process and ensuring the stability of oxygen production and purity.

[0075] Reducing the operating power of the air compressor can decrease the heat load on the equipment, preventing aging and malfunctions caused by prolonged full-load operation, and extending the service life of the oxygen generation module in the air conditioner. At the same time, increasing the operating power of the heat dissipation module helps improve the equipment's heat dissipation effect, further protecting the equipment from high-temperature damage.

[0076] In the implementation process, a temperature sensor is integrated into the oxygen generation module of the air conditioner to monitor the exhaust temperature in real time. A reasonable temperature threshold T is set. limit When the temperature T reaches or exceeds T limit When the system detects excessively high exhaust temperature, it triggers a temperature regulation program. By reducing the operating power of the air compressor, it decreases the heat generated during compression, thereby lowering the exhaust temperature. This process can be gradual, ensuring a smooth transition for the air compressor to the new operating state and preventing system instability due to sudden changes. Simultaneously, the system can enhance the heat dissipation capacity of the equipment and quickly reduce the internal temperature by increasing the operating power of the cooling module. This includes increasing fan speed or activating additional cooling devices, such as a water-cooling system.

[0077] After adjusting the operating parameters, the system continuously monitors changes in exhaust temperature. If the temperature remains above the threshold, the operating status of the air compressor and cooling module is further adjusted until the temperature stabilizes within a safe range. Conversely, if the temperature returns to normal, the system maintains the current operating parameters and continues monitoring.

[0078] To achieve optimal temperature control, the system can dynamically adjust the operating parameters of the air compressor and cooling module by combining historical operating data and optimization algorithms. For example, based on seasonal changes and usage frequency, the system can intelligently predict the required cooling capacity and avoid over-adjustment.

[0079] Air conditioner control methods also include: constructing a pressure threshold P limit Obtain the pipeline pressure P, and compare the pipeline pressure P with the pressure threshold P. limit Compare the results; based on the comparison, control the oxygen generating module to operate at the current pipeline pressure or adjust the pipeline pressure of the oxygen generating module.

[0080] Setting a pressure threshold provides the system with a safe operating pressure range. When the pipeline pressure P exceeds P0... limit In such cases, the system can immediately identify and take measures to reduce pressure, avoiding pipe rupture, equipment damage, or potential safety accidents caused by excessive pressure, thus ensuring the safe operation of the oxygen production system.

[0081] The oxygen separation efficiency of the oxygen generation module is closely related to the pipeline pressure. By controlling the pipeline pressure within the optimal operating range, the working state of adsorption materials such as molecular sieves can be optimized, improving the oxygen separation rate and purity, and ensuring that the output oxygen quality meets user needs.

[0082] Real-time monitoring and intelligent adjustment of pipeline pressure helps to detect potential pressure anomalies, such as leaks and blockages, in advance, facilitating preventative maintenance, reducing the possibility of sudden failures, and ensuring the long-term stable operation of the equipment.

[0083] Based on the comparison results, methods for controlling the oxygen generating module to operate at the current pipeline pressure or adjusting the pipeline pressure of the oxygen generating module include: when the pipeline pressure P is less than the pressure threshold P... limit When the oxygen generating module operates at the current pipeline pressure, the system will control the oxygen generating module to operate at the current pipeline pressure; when the pipeline pressure P is greater than or equal to the pressure threshold P... limit At that time, adjust the pipeline pressure of the oxygen generating module.

[0084] Set pipeline pressure threshold P limit This can effectively prevent safety issues caused by abnormally high pipeline pressure, such as pipeline rupture or equipment damage. When the detected pipeline pressure P reaches or exceeds P... limit In case of an emergency, the system immediately initiates an adjustment program to reduce the gas supply or open the pressure relief valve to ensure the safe operation of the system.

[0085] Excessive pipeline pressure increases mechanical stress on equipment, accelerating wear on components, especially critical parts such as valves and pipe joints. By setting and automatically adjusting pressure thresholds, the system can effectively reduce pressure shocks and extend the service life of the equipment.

[0086] Excessive pipeline pressure leads to increased air compressor energy consumption, while insufficient pressure affects oxygen production. By precisely controlling the pipeline pressure, the system can ensure oxygen production while achieving rational energy utilization and reducing operating costs.

[0087] Methods for adjusting the pipeline pressure of the oxygen generating module include: reducing the gas supply in the pipeline or controlling the pipeline to release pressure.

[0088] By reducing the gas supply in the pipeline or depressurizing, excessive pipeline pressure can be effectively avoided, reducing safety risks such as pipeline rupture and leakage, and providing a higher level of safety for equipment and users.

[0089] Stable pipeline pressure is fundamental to the continuous operation of an oxygen production system. Through real-time monitoring and adjustment, the system can quickly respond to changes in the external environment, such as fluctuations in grid voltage or changes in gas source pressure, ensuring the continuity and stability of the oxygen production process.

[0090] A pressure sensor is integrated into the oxygen generation module of the air conditioner to monitor the pipeline pressure in real time. A safe pressure threshold P is set. limit When the pipeline pressure P exceeds P limit Immediately initiate the pressure regulation procedure. When the pipeline pressure P is greater than or equal to the pressure threshold P... limit In such cases, the system reduces the air supply by lowering the operating power of the air compressor or adjusting the valve opening, thereby reducing the gas pressure in the pipeline and preventing overpressure. The system should include a pressure relief valve or pressure relief control system. When it is necessary to reduce the pipeline pressure, the pressure relief valve is opened to safely release excess gas into the environment, quickly reducing pipeline pressure and ensuring system safety.

[0091] After adjusting the gas supply or depressurizing, the system continuously monitors changes in the pipeline pressure P. If the pressure remains higher than P... limit If the pressure does not stabilize within a safe range, the gas supply will be adjusted or the pressure relief will be increased until the pressure returns to a safe level. If the pressure recovers, the system will maintain its current state and continue to monitor it to ensure pressure stability.

[0092] In practical implementation, the air conditioner control method also includes: constructing a humidity threshold H. limit ; Obtain the module humidity H, and compare the module humidity H with the humidity threshold H limit Compare the results; based on the comparison, control the oxygen generating module to operate at the current module humidity or adjust the humidity value of the oxygen generating module.

[0093] Humidity has a direct impact on the operating efficiency of oxygen generation modules, especially on the performance of adsorption materials such as molecular sieves. This can be addressed by setting a humidity threshold H. limit The system monitors the humidity (H) within the module in real time. When the humidity exceeds the threshold, the system can take corresponding measures to adjust it, thereby optimizing the working state of the adsorption material and improving the purity and yield of oxygen.

[0094] Humidity control helps components such as air compressors and dryers operate under more suitable conditions, reducing unnecessary energy consumption. For example, in a dry environment, the system can appropriately reduce the operating intensity of the dryer, saving energy.

[0095] A stable humidity environment is a prerequisite for the continuous and efficient operation of the oxygen generation module. Through intelligent adjustment, the system can respond promptly to humidity fluctuations, maintaining the equipment at the optimal humidity level, thus enhancing the system's stability and reliability.

[0096] Different geographical locations and seasons can lead to significant variations in humidity levels. By setting humidity thresholds and automatically adjusting them, the system can effectively adapt to various environmental conditions, ensuring the normal functioning of its oxygen production capabilities.

[0097] Based on the comparison results, methods for controlling the oxygen generating module to operate at the current module humidity or adjusting the humidity value of the oxygen generating module include: when the module humidity H is less than the humidity threshold H... limit When the humidity level is high, the oxygen generating module operates at the current humidity value; when the module humidity H is greater than or equal to the humidity threshold H... limit At that time, adjust the humidity value of the oxygen generating module.

[0098] Humidity is one of the key factors affecting oxygen separation efficiency. When the module humidity H exceeds H... limit Excessive moisture may adsorb onto adsorbent materials such as molecular sieves, reducing their selective adsorption of oxygen and thus affecting oxygen purity. By adjusting the humidity level of the oxygen generation module, the system can ensure that the adsorbent materials are in optimal working condition, improving oxygen separation efficiency and increasing oxygen purity.

[0099] In dry environments, the oxygen generation module can operate with higher efficiency because lower humidity means the adsorbent does not require as much energy for moisture adsorption, thus reducing energy consumption. When H > H0 limit At the same time, by adjusting the humidity value, the system can maintain a better working humidity range, optimize energy use, and improve overall operating efficiency.

[0100] Methods for adjusting the humidity value of the oxygen generating module include: increasing the rotation speed of the cooling fan inside the oxygen generating module.

[0101] Increasing the speed of the cooling fan can quickly change the airflow rate inside the oxygen generation module, accelerate the exchange of heat and moisture, and enable the humidity to reach the target value more quickly, thereby improving the accuracy and response speed of humidity control.

[0102] Specifically, a high-precision humidity sensor is installed inside the oxygen generation module to continuously monitor humidity changes within the module, ensuring real-time data acquisition and accuracy. The main control system receives data from the humidity sensor and compares it with a preset humidity threshold H. limit When the detected humidity H≥H limit Upon detection, the system immediately activates its intelligent algorithm to calculate and execute an instruction to increase the cooling fan speed until the humidity drops to the target level. The system features dynamic adjustment of the cooling fan speed, intelligently adjusting the speed increase based on the humidity difference to ensure rapid humidity reduction while preventing excessive energy consumption.

[0103] The system records the changes and effects of the cooling fan speed during each humidity adjustment process. Through machine learning algorithms, it continuously optimizes the speed adjustment strategy to better suit the optimal humidity control practices for specific environments. To prevent the cooling fan from overloading, the system needs to set a speed limit and automatically switch to other humidity control methods, such as activating a dehumidifier, when the speed reaches the limit, ensuring safe operation of the equipment.

[0104] The air conditioner control method also includes: constructing an adsorbent change rate threshold A. limit Obtain the adsorbent change rate A, and compare the adsorbent change rate A with the adsorbent change rate threshold A. limit Compare the results; based on the comparison, control the oxygen generation module to operate with the current operating parameters or adjust the adsorption time of the adsorbent.

[0105] Adsorbent performance directly affects the quality and efficiency of oxygen production. This is achieved by constructing an adsorbent change rate threshold A. limit And monitor the change rate A of the adsorbent. When A ≥ A limit In this case, the system can promptly identify situations where the adsorbent performance declines and compensate for the loss of adsorbent performance by adjusting the adsorption time, thereby ensuring that the oxygen output of the oxygen production system remains at a high purity level.

[0106] Adsorbent performance degrades over time, especially under conditions of frequent start-stop cycles or high-load operation. By comparing with Alimit, timely adjustment of adsorption time can avoid overuse of the adsorbent, slow down its performance degradation rate, extend the adsorbent's lifespan, and reduce the frequency and cost of adsorbent replacement.

[0107] Adsorbent performance is affected by a variety of factors, including temperature, humidity, and operating time. By setting the Alimit, the system can automatically adapt to these changes and dynamically adjust the adsorption time based on the real-time monitored rate of adsorbent change A, maintaining stable operation of the system under various environmental conditions.

[0108] Based on the comparison results, methods for controlling the oxygen generation module to operate with the current operating parameters or adjusting the adsorption time of the adsorbent include: when the adsorbent change rate A is less than the adsorbent change rate threshold A... limit When the oxygen generation module operates at the current adsorbent change rate, the adsorbent change rate A is greater than or equal to the adsorbent change rate threshold A. limit This extends the adsorption time of the adsorbent while shortening the desorption time.

[0109] The rate of change A of the adsorbent reflects the effective adsorption capacity and regeneration efficiency of the adsorbent. When A limit When A ≥ A, it indicates that the adsorbent is still in good working condition, and there is no need to adjust the adsorption time. Conversely, when A ≥ A limit At this point, the adsorbent may be partially saturated or its performance may have declined. By extending the adsorption time, the adsorbent can adsorb oxygen more fully, thereby increasing oxygen production. At the same time, shortening the desorption time can accelerate the circulation rate, which helps to improve oxygen purity and system operating efficiency.

[0110] Adsorption is an energy-intensive process; extending the adsorption time can reduce the energy consumption required for the desorption stage, as desorption typically requires higher temperatures or pressures, consuming more energy. (When A≥A) limit By optimizing the adsorption / desorption time allocation, the system can reduce energy waste and improve energy utilization efficiency while meeting oxygen production requirements.

[0111] Based on the comparison results, methods for continuing to adjust the actual operating parameters or ending the adjustment program include: ensuring the actual total oxygen amount C is less than the total oxygen amount threshold C. m Continue to adjust the actual operating parameters of the oxygen generating module; ensure that the actual total oxygen quantity C is greater than or equal to the total oxygen quantity threshold C. m When the time comes, the adjustment procedure ends.

[0112] By setting a total oxygen threshold C m The system can ensure that the total amount of oxygen produced reaches the expected target. When C < C m In certain situations, the system will automatically adjust the operating parameters of the oxygen-generating module, such as increasing adsorption time, adjusting pressure or temperature, to increase oxygen production until C reaches or exceeds C60. m To achieve the production target. When C≥C m ​When the system determines that oxygen production has met demand, it will terminate the adjustment process, avoiding unnecessary energy consumption and equipment wear. This demand-based dynamic adjustment mechanism helps optimize resource utilization efficiency in key processes such as air compression and adsorption separation.

[0113] This application also provides an air conditioner, applicable to the air conditioner control method of the above embodiments. The air conditioner includes: an oxygen generating module, which includes an air compressor and a molecular sieve component, and the air compressor and the molecular sieve component are connected by a connecting pipeline; the oxygen generating module also includes a heat dissipation module, which includes a heat dissipation fan, which is arranged opposite to the air compressor to dissipate heat from the air compressor.

[0114] The air conditioner also includes an outdoor unit, which includes a first installation space and a second installation space that are interconnected. An oxygen generating module is installed in the first installation space, and an axial flow fan is installed in the second installation space. The axial flow fan guides part of the airflow in the first installation space and discharges it to the outdoor unit.

[0115] By optimizing the operating parameters of the air conditioner's oxygen generation module, especially with adaptive optimization after long-term shutdown, the system can quickly adjust to the most suitable state for the current environment, maximizing oxygen generation efficiency. The addition of a heat dissipation module, particularly the relative arrangement of the cooling fan and the air compressor, effectively solves the problem of heat accumulation caused by the air compressor's operation, preventing high temperatures from adversely affecting the performance of the molecular sieve components and ensuring the efficient operation of the oxygen generation process.

[0116] Dynamic adjustment of the cooling fan can not only maintain the internal humidity of the system within a suitable range, avoiding damage to electronic components and adsorbents from moisture, but also effectively control the temperature of the air compressor, preventing overheating, thereby reducing equipment wear, extending the service life of the air compressor and molecular sieve components, and reducing long-term maintenance costs.

[0117] Real-time monitoring and dynamic adjustment of environmental parameters enable the oxygen generating module to quickly adapt to different working conditions, such as changes in temperature, pressure, and humidity. This adaptive capability helps maintain stable system operation, reduces fluctuations in oxygen production and purity caused by environmental changes, and ensures users receive a consistent supply of high-quality oxygen.

[0118] The axial flow fan effectively regulates the airflow environment within the primary installation space, helping to reduce the heat generated by the oxygen generator module during operation and preventing overheating. Simultaneously, it promotes fresh air circulation, providing high-quality raw material air for the oxygen generation process, thereby optimizing the working conditions of the oxygen generator module and increasing oxygen production and purity. The axial flow fan also increases air velocity, improving the heat exchange efficiency between the primary installation space and the outside environment, effectively cooling heat-generating components such as the oxygen generator module, preventing performance degradation or malfunction due to overheating, and extending the equipment's lifespan.

[0119] Effective thermal management and airflow circulation can reduce internal temperature gradients and thermal stress, preventing localized overheating and improving overall system stability. Simultaneously, timely removal of moisture and contaminants from the initial installation space minimizes the impact on adsorbent performance, ensuring the continuous reliability of the oxygen production process. The efficient airflow from the axial fan reduces energy consumption of the oxygen production module, especially in high-temperature or high-humidity environments. Good heat dissipation and airflow circulation lower the cooling energy required for system operation, achieving energy conservation and emission reduction goals.

[0120] This application primarily addresses the issue that when an oxygen generation system restarts after a long-term shutdown, the internal physical and chemical environment may undergo significant changes. These changes can cause the original parameter settings to fail to meet the operational requirements after restarting, resulting in lower-than-expected oxygen production and purity. Utilizing the air conditioner control method described in the above embodiments, by real-time monitoring of changes in the internal physical and chemical environment of the oxygen generation equipment, combined with historical operating data and optimization algorithms, the operating parameters of the oxygen generation system are dynamically adjusted, thereby quickly reaching the optimal operating state after restarting.

[0121] Specifically, temperature sensors, pressure sensors, humidity sensors, and adsorbent performance monitoring devices are installed in the adsorption tower, pipelines, and control system of the oxygen production system. These sensors can collect environmental parameter data inside the equipment in real time and transmit it to the main control system through the data acquisition module. When the oxygen production system is restarted after a long-term shutdown, the main control system first retrieves the environmental parameter data collected during the shutdown period and analyzes the changing trends of parameters such as temperature, pressure, and humidity inside the equipment. Based on the environmental change analysis results and combined with historical operating data, the system calculates the optimal adsorption and desorption times using optimization algorithms (such as genetic algorithms). After adjusting the parameters, the system monitors changes in oxygen production in real time. If the oxygen production does not reach the expected value, the system will further adjust the pressure regulation parameters; through multiple iterative optimizations, the oxygen production system is ultimately brought to its optimal operating state.

[0122] The control method is as follows:

[0123] Step 1: After the air conditioner oxygen production mode is started, the parameters are initialized and dynamically calibrated. The system ambient temperature, system pressure, system humidity and adsorbent performance are collected.

[0124] Step 2: Analyze the detected parameters.

[0125] (1) Determine the current system temperature T and T limit The relationship when T <T limit When T = 115℃, it indicates that the current temperature is within the logic control range, and the current state will be maintained; when T ≥ T limitWhen the temperature reaches 115℃, retrieve historical operating data for further assessment, gradually reduce the heating power or increase cooling measures, and slowly lower the temperature to the limit value.

[0126] (2) Determine the current system pressure P and P limit The relationship when P <P limit When P = 0.15 MPa, it indicates that the current pressure is within the logic control range, and the current state should be maintained; when P ≥ P limit When the pressure is 0.15 MPa, retrieve historical operating data for further judgment, gradually reduce the gas supply or increase pressure relief measures, and slowly reduce the pressure to the limit value.

[0127] (3) Determine the current system humidity H and H limit The relationship when H <H limit When H = 60%, it indicates that the current humidity is within the logical control range, and the current state will be maintained; when H ≥ H limit When the humidity reaches 60%, historical operating data will be retrieved for further assessment. Ventilation measures will be increased to gradually reduce the humidity to the maximum limit.

[0128] (4) Determine the current adsorbent performance A and A limit The relationship when A limit When A = 10%, it indicates that the current adsorbent performance is within the logical control range, and the current state should be maintained; when A ≥ A limit When the adsorption rate is 10%, historical operating data is retrieved for further assessment. The adsorption time is extended by 5%, and the desorption time is shortened by 3%.

[0129] Step 3: Based on the above parameters, the adaptive feedback mechanism monitors changes in oxygen production in real time. If the oxygen production does not reach the expected value C < C m The system will further adjust the pressure regulation parameters and optimize them through multiple iterations to ultimately bring the oxygen generation system to its optimal operating state.

[0130] ​In this application, the adsorbent change rate refers to the degree to which the adsorption performance of an adsorbent changes over time or with the number of uses during its use. Specifically, it is an important indicator for measuring the proportion of performance degradation of an adsorbent from its initial state to a certain point in time. In the oxygen generation system of an air conditioner, molecular sieves or other types of adsorbents are used to separate oxygen from other gases in the air. Over time, the surface of the adsorbent may become contaminated, the pores may become clogged, or changes in its physicochemical properties may occur, all of which affect its ability to adsorb oxygen. Monitoring the adsorbent change rate is crucial in the oxygen generation system of an air conditioner because it directly relates to whether the system can generate oxygen stably and efficiently. When the adsorbent change rate reaches a certain threshold, the system needs to take corresponding measures, such as extending the adsorption time, increasing the regeneration frequency, or replacing the adsorbent with a new one, to restore or compensate for the decline in adsorbent performance, ensuring the normal operation of the oxygen generation system and the quality of the oxygen product.

[0131] Pressure swing adsorption (PSA) systems typically consist of two or more adsorption towers. While one tower undergoes desorption and regeneration, the other tower continues the adsorption process. Through this alternating cycle, oxygen-enriched gas can be continuously produced.

[0132] Desorption time is a key parameter in the operation of an oxygen generation system, specifically referring to the time period during the adsorption-desorption cycle during which adsorbed gases (such as nitrogen) are released from the adsorbent. In an oxygen generation system, molecular sieves or other highly selective adsorbents first adsorb nitrogen from the air during the adsorption phase, thereby enriching the oxygen supply. However, as the adsorption process continues, the adsorbent gradually reaches its adsorption saturation state. At this point, the desorption phase is required. By changing the pressure, temperature, or both simultaneously, the adsorbed nitrogen in the adsorbent is released so that the adsorbent can be reused.

[0133] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0134] By acquiring key operational parameters of the oxygen generation module in real time (including exhaust temperature, pipeline pressure, module humidity, and adsorbent change rate) and comparing them with preset parameter thresholds, the system can immediately identify any changes outside the normal range. This real-time monitoring capability ensures that the system can react quickly and take necessary parameter adjustment measures to prevent low oxygen generation efficiency or system failure caused by abnormal parameters.

[0135] Based on parameter adjustments, the system further monitors the actual total amount of oxygen produced (C) and compares it with the set total oxygen threshold (C). m This closed-loop control strategy can promptly detect and correct situations where oxygen production is insufficient or purity is substandard, ensuring that the quality of the output oxygen always meets user needs.

[0136] This addresses the issue that when an oxygen generation system is restarted after a long period of shutdown, the internal physical and chemical environment may undergo significant changes. These changes could cause the original parameter settings to fail to meet the operational requirements after restarting, resulting in lower-than-expected oxygen production and purity.
