Description

Technical Field

[0001] This invention belongs to the field of indoor air conditioning technology, specifically relating to an integrated oxygen-rich and hydrogen-rich humidification environment conditioning system and its control method. Background Technology

[0002] In high-altitude areas above 3,000 meters, the air is thin and the oxygen content is low, and conventional indoor environmental control equipment has serious compatibility defects. The oxygen concentration produced by existing oxygen generators is still mainly 93%±3%, and this concentration can only be maintained at low flow rates (1–2 L / min). When the flow rate is increased to 3–5 L / min, the oxygen concentration drops significantly, and some models even drop below 80%, which cannot meet the high-flow oxygen supply needs of enclosed spaces in high-altitude areas. Furthermore, in existing technologies, air separation oxygen generators, humidifiers, and negative ion (or hydrogen ion) generators are mostly independent devices. Independent operation has problems such as occupying more space, high energy consumption, uncoordinated control, and mutual interference of environmental parameter adjustments (such as some humidification methods may affect the concentration of negative ions).

[0003] Currently, there is a lack of an environmental regulation system specifically designed for high-altitude areas that can stably output medium-concentration, high-flow-rate oxygen and integrate intelligent and coordinated regulation of oxygen enrichment, hydrogen enrichment, and humidification. Summary of the Invention

[0004] To address the aforementioned technical problems, one aspect of the present invention proposes an integrated oxygen- and hydrogen-enriched humidification environment control system, comprising a housing and an integrated air separation module, a humidification module, a hydrogen ion generation module, a control module, an output unit, and a water tank. The air separation module includes a molecular sieve and a double-tower molecular sieve alternating adsorption structure for producing oxygen-enriched gas with an oxygen concentration of 50% ± 3%. Both the humidification module and the hydrogen ion generation module are connected to the water tank via water pipes. The hydrogen outlet of the hydrogen ion generation module is connected to the humidification module, allowing the hydrogen gas to be atomized and discharged. The control module is electrically connected to the air separation module, the humidification module, and the hydrogen ion generation module, and is also connected to the oxygen concentration sensor, the humidity sensor, and the hydrogen concentration sensor for signal transmission. It is used to collect real-time data from each sensor and regulate the operating status of each module. The output unit is used to mix the oxygen-enriched gas output from the air separation module with the hydrogen-enriched atomized water mist output from the humidification module and then output the mixture to the room.

[0005] Optionally, the air separation module is located in the middle of the housing, the control module is located in the upper part of the housing, the humidification module, the hydrogen ion generation module and the water tank are located in the lower part of the housing, and the output unit is set corresponding to the air outlet of the housing.

[0006] Optionally, the molecular sieve is embedded in the adsorption chamber of the air separation module, and the adsorption chamber corresponds one-to-one with the dual-tower molecular sieve. The dual-tower molecular sieve is connected to the switching pipeline through a solenoid valve, and the switching pipeline is connected to the first input end of the output unit.

[0007] Optionally, the dual-tower molecular sieve is symmetrically arranged inside the air separation module. The control module is electrically connected to the corresponding solenoid valve of the dual-tower molecular sieve through wires. By adjusting the opening and closing of the solenoid valve, the adsorption and desorption switching rhythm of the dual-tower molecular sieve is controlled to achieve uninterrupted continuous oxygen production.

[0008] Optionally, the atomization input end of the humidification module is connected to the hydrogen outlet of the hydrogen ion generation module, and the atomization output end is connected to the second input end of the output unit; the humidification module uses ultrasonic atomization, cold evaporation or hot evaporation to mix and atomize the hydrogen input from the hydrogen ion generation module with the water in the water tank to form hydrogen-rich atomized water mist, which is then delivered to the output unit.

[0009] Optionally, the oxygen concentration sensor, humidity sensor, and hydrogen concentration sensor are installed at the air inlet or air outlet of the housing. The oxygen concentration sensor, humidity sensor, and hydrogen concentration sensor are all bidirectionally connected to the control module through signal lines. The control module has a built-in operating condition calibration module, which automatically locks the oxygen supply range of 50%±3% after power-on, and collects feedback data from each sensor in real time and makes adjustments accordingly.

[0010] Optionally, the control module has an interactive interface on its surface and multiple preset modes, including at least a sleep aid mode, an office mode, and a sports recovery mode. The preset modes correspond to preset oxygen concentration, humidity, and hydrogen concentration parameters. The control module controls the working status of each module through wire linkage.

[0011] Another aspect of the present invention provides a control method for an integrated oxygen- and hydrogen-rich humidification environment conditioning system, comprising the following steps: S1: Operating condition calibration. After the system is turned on, it automatically locks the safe oxygen supply range of 50%±3% target oxygen concentration and 20L / min rated flow rate. S2: Parameter and mode settings. Users can set target humidity and hydrogen concentration parameters through the interactive interface, or select a preset health mode. S3: Continuous oxygen production control. The control module drives the air separation module to work in a dual-tower alternating adsorption mode to ensure that the oxygen concentration is stable at 50%±3%, and the produced oxygen-enriched gas is delivered to the output unit. S4: Hydrogen atomization control. The control module starts the hydrogen ion generation module and the humidification module. The hydrogen ion generation module obtains water from the water tank to produce hydrogen, which is then delivered to the humidification module through the hydrogen outlet. The humidification module mixes and atomizes the hydrogen with the water in the water tank to form hydrogen-rich atomized water mist, which is then delivered to the output unit. S5: Coordinated hybrid output regulation. The output unit mixes oxygen-rich gas with hydrogen-rich atomized water mist and outputs it indoors. The control module collects feedback data from various sensors in real time, compares it with user-set parameters or preset mode parameters, and fine-tunes oxygen flow rate and atomization power to ensure that indoor oxygen concentration, humidity, and hydrogen concentration remain stable within the target range for a long time.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes molecular sieves and dual-tower alternating adsorption to stably output 50%±3% medium-concentration oxygen at a high flow rate of 20L / min, satisfying oxygen supplementation needs while eliminating the safety hazards of high-concentration oxygen; direct oxygen emission and hydrogen atomization emission are suitable for the indoor environmental regulation needs of high-altitude areas. It integrates stable oxygen production, hydrogen atomization, humidification, intelligent control and mixed output into one unit. All modules are integrated into the same housing, saving space, reducing energy consumption and avoiding the drawbacks of multiple devices operating independently. Medium-concentration oxygen is more suitable for long-term use. It features fully automatic closed-loop control, with hydrogen being atomized and mixed with oxygen-enriched gas for safer output, adapting to the environmental adjustment needs of different scenarios.

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

Example 1

[0018] like Figure 1 As shown, an integrated oxygen- and hydrogen-enriched humidification environment control system includes a housing. The top of the housing has an air outlet (corresponding to the output unit), and the lower side has an air inlet. A dust filter is installed at the air inlet; it is removable and washable to prevent sand and dust from entering the housing and damaging the modules. The bottom of the housing has anti-slip pads to enhance stability. The interior of the housing adopts a partitioned design, divided from top to bottom into an upper control zone, a middle oxygen generation zone, and a lower humidification hydrogen generation zone. Sealed partitions separate each zone to prevent water vapor and hydrogen from entering the control and oxygen generation zones, ensuring safe operation. An air separation module 1 is fixed in the middle oxygen generation zone of the housing and includes an adsorption chamber, a dual-tower molecular sieve, a solenoid valve, a switching pipeline, an air intake fan, and a flow regulating valve. The adsorption chamber consists of two independent cylindrical cavities, each corresponding to a dual-tower molecular sieve. The molecular sieve uses a 13X type medical molecular sieve with a particle size of 2-3 mm, and a filling weight of 1.2 kg per adsorption chamber. This type of molecular sieve can efficiently adsorb nitrogen from the air even in low-pressure environments at high altitudes, ensuring a stable oxygen concentration.

[0019] The dual-tower molecular sieve is symmetrically arranged in two adsorption chambers and sealed to the adsorption chambers via flanges, facilitating future replacement and maintenance. Two two-position three-way solenoid valves are selected and connected to the inlet and outlet of each adsorption chamber respectively. One end of the switching pipeline is connected to the solenoid valve, and the other end is connected to the first input end of the output unit. A flow regulating valve is installed in the middle of the switching pipeline to regulate the output flow rate of oxygen-enriched gas, with a range of 0-30L / min, which can accurately match the rated flow rate requirement of 20L / min.

[0020] The intake fan is a low-noise centrifugal fan (2800 r / min speed, 1200 Pa air pressure), installed at the intake end of the air separation module 1 and connected to the air inlet of the housing. It is used to draw outdoor air into the adsorption chamber. The fan adopts frequency conversion control and can automatically adjust the speed according to the oxygen concentration at the air inlet to ensure adsorption efficiency.

[0021] Humidification module 2 and hydrogen ion generation module 3 are both installed in the humidification and hydrogen generation area at the bottom of the housing, arranged side by side with water tank 5. Water tank 5 has a water inlet (with a sealing cap) at the top and a drain outlet at the bottom. A water level sensor is installed inside water tank 5 to detect the water level in real time. When the water level is lower than the warning value, a signal is sent to control module 4 to trigger an alarm and stop the machine to prevent the module from burning out and being damaged.

[0022] The humidification module 2 uses ultrasonic atomization to meet the atomization needs of high-altitude, low-pressure environments. It includes an atomizing plate, an atomizing chamber, and a mist guide tube. The atomizing plate is a 2.4MHz high-frequency atomizing plate with an adjustable atomization rate (100-300ml / h). The atomizing chamber is connected to the water tank 5 via a water pipe, which is equipped with a miniature water pump to deliver water from the water tank 5 to the atomizing chamber. The input end of the atomizing chamber is connected to the hydrogen outlet of the hydrogen ion generation module 3, and the output end is connected to the second input end of the output unit via the mist guide tube to ensure that the hydrogen can be fully mixed with the atomized water mist.

[0023] The humidification module can also use a cold evaporation method, specifically including a polymer fiber wet curtain (10-15mm thick, air permeability ≥85%), a low-noise axial flow fan, and a water guide pipe. The wet curtain and water tank 5 are connected through the water guide pipe to achieve automatic water replenishment. The matching fan speed is 1500-2500r / min and the air pressure is 800-1000Pa. The fan speed can be adjusted according to the humidity requirements to avoid insufficient atomization under low air pressure. Hydrogen is introduced through one side of the wet curtain and mixed with the water mist formed by evaporation before being delivered to the output unit. Alternatively, a hot evaporation method can be used, specifically including a PTC heating element, an evaporation chamber, a temperature sensor, and a condensation reflux structure. The PTC heating element power is adjustable from 50-100W. The temperature sensor monitors the heating temperature in real time (controlled at 80-90℃) to prevent dry burning. The evaporation chamber is connected to the hydrogen outlet to ensure that the hydrogen and water vapor are fully mixed. The condensation reflux structure can return the unevaporated water vapor to the water tank 5 to reduce water waste. The mixed hydrogen-rich water vapor is delivered to the output unit through the mist guide pipe.

[0024] The hydrogen ion generating module 3 uses an electrolytic hydrogen ion generator, including an electrolytic cell, electrode plates, and a gas-liquid separator. The electrolytic cell is connected to the water tank 5 via a water pipe. After the hydrogen generated by electrolysis is separated from the water by the gas-liquid separator, it is delivered to the atomization chamber of the humidification module 2 through a one-way valve (to prevent water mist backflow). The hydrogen output flow rate is adjustable (10-50 ml / min) to ensure that the hydrogen concentration is controlled within a safe range.

[0025] The control module 4 is installed in the upper control area of ​​the housing. It uses an STM32F407 microcontroller as the main control chip and has built-in operating condition calibration module, data acquisition module and linkage control module 4. The surface is equipped with a 7-inch touch screen interface, which can display real-time oxygen concentration, humidity, hydrogen concentration, water level in water tank 5 and equipment operating status. It also supports manual parameter setting and preset mode selection.

[0026] The sensors include an oxygen concentration sensor, a humidity sensor, and a hydrogen concentration sensor, all installed at the air outlet of the housing, close to the output unit, to collect parameters of the mixed gas for more accurate detection. The oxygen concentration sensor is an electrochemical type, model ME2-O2, with a range of 0-100%VOL and an accuracy of ±1%VOL, used to detect and output the concentration of oxygen-enriched gas in real time. The humidity sensor is a capacitive type, model DHT22, with a range of 0-99%RH and an accuracy of ±2%RH, and detects the humidity of the atomized air. The hydrogen concentration sensor is a catalytic combustion type, model MQ-8, with a range of 0-1000ppm and an accuracy of ±50ppm. It is used to detect hydrogen concentration and prevent hydrogen leakage from exceeding the limit.

[0027] All sensors are bidirectionally connected to the control module 4 via signal lines. The control module 4 can collect sensor feedback data in real time and send calibration signals to the sensors to ensure detection accuracy. The control module 4 is electrically connected to the fan and solenoid valve in the air separation module 1, the atomizing plate and micro water pump in the humidification module 2, and the electrolytic cell in the hydrogen ion generation module 3 via wires to realize the linkage control of each module.

[0028] The output unit is located at the air outlet on the top of the housing, including a mixing chamber and a louvered air outlet. It has two input terminals, which are connected to the switching pipeline of the air separation module 1 and the mist guide pipe of the humidification module 2, respectively. The mixing chamber is equipped with a baffle plate to ensure that the oxygen-rich gas and the hydrogen-rich atomized water mist are fully mixed and to avoid stratification. The louvered air outlet of the air outlet fan can be manually adjusted to adjust the air outlet angle (0-90°) to adapt to the air supply needs of different indoor layouts. Example 2

[0029] This embodiment optimizes the air inlet of the air separation module 1 based on embodiment 1, integrating a HEPA filter, an activated carbon filter, and a negative ion generator to achieve multi-stage filtration and purification of the intake air, further improving the cleanliness of the output gas and adapting to indoor and outdoor environments with high altitudes, dust, and poor air quality. The remaining structure and control methods remain consistent with embodiment 1; only the air inlet purification structure and related adaptability are adjusted. At the air inlet on the lower side of the housing, an activated carbon filter and a HEPA filter are added sequentially from the outside to the inside, based on the original dust filter. A negative ion generator is integrated inside the HEPA filter, forming a four-stage purification structure of "dust prevention + activated carbon adsorption + HEPA fine filtration + negative ion sterilization." All filters are detachable and sealed to the air inlet slot for easy regular cleaning or replacement. Specific parameters are as follows: HEPA filter: Uses H13 grade high-efficiency filter with pore size of 0.3μm and filtration efficiency ≥99.97%. It can effectively filter PM2.5, fine dust, pollen, bacteria and other suspended particulate matter in the air. It is suitable for the high-altitude and dusty environment. The filter size matches the air inlet (300mm long × 200mm wide × 20mm thick). Activated carbon filter: Made of honeycomb activated carbon material, with a filling amount of 150g and a specific surface area of ​​≥1000m² / g, it can efficiently adsorb formaldehyde, odors, and harmful gases in the air (such as a small amount of residual exhaust gas that may exist in high-altitude areas), while also assisting in filtering larger particulate impurities and extending the service life of the HEPA filter. Negative ion generator: A low-temperature plasma negative ion generator (operating voltage 12V DC, power 5W) is selected and installed inside the HEPA filter and at the front of the air intake fan, producing a negative ion concentration of 1×10⁻⁶. 6 The negative ion generator has a capacity of 1 ion / cm³, which can sterilize and disinfect air after multi-stage filtration, destroy the cell membranes of bacteria and viruses, and cause fine particulate matter in the air to agglomerate and settle, further improving air cleanliness. The negative ion generator is electrically connected to the control module 4 and can automatically start, stop or adjust the power according to the air quality.

[0030] After optimization, the air intake path of the air separation module 1 is as follows: outdoor air → dust filter (coarsely filters sand and dust) → activated carbon filter (adsorbs odors and harmful gases) → HEPA filter (finely filters fine particulate matter) → negative ion generator (sterilizes and settles particulate matter) → air intake fan → adsorption chamber. This ensures that the air entering the oxygen generation system is clean and free of impurities, which not only prevents sand and impurities from damaging core components such as molecular sieves and solenoid valves, but also improves the cleanliness of the output oxygen-rich and hydrogen-rich gas, thus protecting human respiratory health. Because the addition of multiple filters at the air inlet creates some air resistance, the intake fan has been adapted and adjusted. The original low-noise centrifugal fan has been replaced with a high-pressure variable frequency centrifugal fan to ensure sufficient air intake even with multi-stage filtration, meeting the rated oxygen flow requirement of 20L / min. The control module 4 has a built-in air quality detection module that is linked with the negative ion generator. It can automatically adjust the power of the negative ion generator and the speed of the intake fan according to the air quality (PM2.5 concentration) at the air inlet, balancing the purification effect and air intake efficiency. Example 3

[0031] like Figure 2 As shown, the control method of the integrated oxygen-rich and hydrogen-rich humidification environment conditioning system includes the following steps: Detailed implementation process. S1: Operating Condition Calibration When the user connects the power supply to the equipment and presses the power button, the system automatically enters the initialization state. The control module 4 drives each sensor to perform self-tests, and at the same time, the air intake fan of the air separation module 1 starts to run unloaded for 3 minutes to expel the residual gas in the adsorption chamber. Subsequently, the operating condition calibration module automatically locks the target oxygen concentration of 50%±3% and the rated flow rate of 20L / min into a safe oxygen supply range. At the same time, it calibrates the default target values ​​for humidity (50%RH) and hydrogen concentration (300ppm), and detects the water level in the water tank 5 and the circuit connection status of each module. If an abnormality is detected (such as low water level or sensor failure), the interactive interface displays an alarm message, and the equipment stops until the fault is resolved and restarted.

[0032] S2: Parameter and Mode Settings Users can set parameters through a touch interface, and can choose from two methods: ① Manual settings: Manually input the target oxygen concentration (adjustable from 47% to 53%), target humidity (adjustable from 40% to 70% RH), and target hydrogen concentration (adjustable from 100 to 500 ppm); ② Preset Mode Selection: Select from the built-in sleep aid mode, office mode, and sports recovery mode. The parameters for each preset mode are as follows: Sleep aid mode: Oxygen concentration 48%±3%, humidity 55%±2%RH, hydrogen concentration 200±50ppm, low fan speed (1500r / min) to reduce noise and suit nighttime sleep scenarios. Office mode: Oxygen concentration 50%±3%, humidity 50%±2%RH, hydrogen concentration 300±50ppm, air outlet fan speed (2200r / min), balancing comfort and work efficiency; Exercise recovery mode: Oxygen concentration 52%±3%, humidity 60%±2%RH, hydrogen concentration 400±50ppm, high-speed air outlet fan (3000r / min), quickly replenishing oxygen and water to aid post-exercise recovery.

[0033] After the parameters are set, the control module 4 saves the settings and enters the running state.

[0034] S3: Continuous oxygen production control Control module 4 drives air separation module 1 to start, and the intake fan starts working, drawing outdoor air into the adsorption chamber through the dust filter. At the same time, it controls two solenoid valves to alternately open and close, regulating the adsorption and desorption switching rhythm of the dual-tower molecular sieve: the first tower molecular sieve performs adsorption (adsorbing nitrogen from the air to produce oxygen-rich gas), with an adsorption time set to 8 minutes; the second tower molecular sieve performs desorption (discharging adsorbed nitrogen and regenerating for later use), with a desorption time set to 4 minutes; after 8 minutes, the solenoid valves switch, the first tower enters the desorption state, and the second tower enters the adsorption state, repeating the cycle to achieve uninterrupted continuous oxygen production.

[0035] The oxygen concentration sensor collects the oxygen-enriched gas concentration in real time and feeds it back to the control module 4. If the oxygen concentration is detected to be lower than 47%, the control module 4 adjusts the flow regulating valve to increase the oxygen production flow rate (maximum not exceeding 25L / min) and at the same time increases the speed of the intake fan to increase the air intake. If the oxygen concentration is detected to be higher than 53%, the oxygen production flow rate is reduced and the fan speed is reduced to ensure that the oxygen concentration is stable within the target range of 50%±3%. The produced oxygen-enriched gas is transported to the mixing chamber of the output unit through the switching pipeline.

[0036] S4: Hydrogen atomization control Control module 4 synchronously starts hydrogen ion generating module 3 and humidifying module 2: the electrolyzer of hydrogen ion generating module 3 obtains water from water tank 5 and undergoes electrolysis under the action of electrode plates to generate hydrogen. After the hydrogen is separated from water by gas-liquid separator, it is delivered to the atomization chamber of humidifying module 2 through a one-way valve. At the same time, the micro water pump delivers water from water tank 5 to atomization chamber, the atomizing plate is activated, and the water is atomized into tiny water mists, which are fully mixed with the input hydrogen to form hydrogen-rich atomized water mist (the hydrogen concentration is consistent with the set target value). The hydrogen-rich atomized water mist is delivered to the mixing chamber of the output unit through the mist guide tube.

[0037] During the process, the hydrogen concentration sensor detects the hydrogen concentration after atomization in real time. If the detected hydrogen concentration is higher than the upper limit of the set value, the control module 4 reduces the electrolysis power of the hydrogen ion generation module 3 to reduce the amount of hydrogen produced; if it is lower than the lower limit of the set value, the electrolysis power is increased to ensure the hydrogen concentration is stable. The atomization power of the humidification module 2 is adjusted according to the humidity setting value, and the atomization amount changes dynamically with the humidity demand.

[0038] Collaborative Hybrid Output Regulation The mixing chamber of the output unit uses a guide vane to thoroughly mix oxygen-rich gas and hydrogen-rich atomized water mist. The outlet fan adjusts its speed according to the set mode, delivering the mixed oxygen-rich and hydrogen-rich humidified gas into the room through a louvered outlet. Control module 4 collects feedback data from oxygen concentration, humidity, and hydrogen concentration sensors every second, compares it with user-set parameters or preset mode parameters, and performs real-time fine-tuning. When the oxygen concentration deviation is ±1%, adjust the oxygen production flow rate by ±1L / min to ensure stable concentration. When the humidity deviation is ±2%RH, adjust the atomization power of humidification module 2 by ±5W to change the atomization amount; When the hydrogen concentration deviates by ±50ppm, adjust the electrolysis current of the hydrogen ion generation module 3 by ±0.5A to adjust the hydrogen production.

[0039] Meanwhile, the water level sensor monitors the water level in water tank 5 in real time. When the water level is lower than the warning value, the control module 4 triggers an audible and visual alarm and shuts down the hydrogen ion generator module 3 and the humidification module 2, leaving only the air separation module 1 running at low load until the user adds water and the system returns to normal. If the hydrogen concentration is detected to exceed 1000ppm (safe threshold), the control module 4 immediately shuts down the hydrogen ion generator module 3, starts the exhaust fan to run at high speed to expel the excessive hydrogen from the room, and issues an alarm until the hydrogen concentration drops to a safe range.

[0040] When the user shuts down the device, the system enters the shutdown process. Control module 4 first shuts down the operation of each module, starts the fan to run under no-load for 5 minutes to expel residual hydrogen and oxygen-enriched gas from the casing, and then cuts off the power to complete the shutdown.

[0041] Example Effect Verification The system of this embodiment was placed in enclosed rooms with an area of ​​20㎡ at altitudes of 3000 meters, 4000 meters, and 5000 meters, respectively. After powering on, the system was selected in office mode (target oxygen concentration 50%±3%, humidity 50%±2%RH, hydrogen concentration 300±50ppm) and ran continuously for 24 hours. The test results are as follows:

[0042] Energy consumption: The total operating power of the machine is ≤150W, which is 40% lower than that of a traditional independent oxygen concentrator + humidifier + hydrogen ion generator (total power ≥250W). Space occupancy: The entire unit has a volume of only 0.095m³, which reduces space occupancy by 60% compared to independent equipment combinations.

[0043] Verification results show that the system in this embodiment can operate stably in a plateau environment at an altitude of 3,000-5,000 meters, achieving integrated and coordinated control of oxygen enrichment, hydrogen enrichment, and humidification, meeting the needs of indoor environmental regulation in plateau areas, and possessing the advantages of energy saving, space saving, and safety and reliability.

[0044] The above detailed description of an integrated oxygen- and hydrogen-enriched humidification environment control system with reference to the embodiments is illustrative rather than limiting. Several embodiments can be listed according to the defined scope. Therefore, changes and modifications without departing from the overall concept of the present invention should be within the protection scope of the present invention.

7. The integrated oxygen- and hydrogen-enriched humidification environment control system according to claim 1, characterized in that, The control module has an interactive interface on its surface and multiple preset modes, including at least a sleep aid mode, an office mode, and a sports recovery mode. Each preset mode corresponds to preset oxygen concentration, humidity, and hydrogen concentration parameters. The control module controls the working status of each module through wire linkage.

8. A control method for an integrated oxygen-rich and hydrogen-rich humidification environment conditioning system according to any one of claims 1-7, characterized in that, Includes the following steps: S1: Operating condition calibration. After the system is turned on, it automatically locks the safe oxygen supply range of 50%±3% target oxygen concentration and 20L / min rated flow rate. S2: Parameter and mode settings. Users can set target humidity and hydrogen concentration parameters through the interactive interface, or select a preset health mode. S3: Continuous oxygen production control. The control module drives the air separation module to work in a dual-tower alternating adsorption mode to ensure that the oxygen concentration is stable at 50%±3%, and the produced oxygen-enriched gas is delivered to the output unit. S4: Hydrogen atomization control. The control module starts the hydrogen ion generation module and the humidification module. The hydrogen ion generation module obtains water from the water tank to produce hydrogen, which is then delivered to the humidification module through the hydrogen outlet. The humidification module mixes and atomizes the hydrogen with the water in the water tank to form hydrogen-rich atomized water mist, which is then delivered to the output unit. S5: Coordinated hybrid output regulation. The output unit mixes oxygen-rich gas with hydrogen-rich atomized water mist and outputs it indoors. The control module collects feedback data from each sensor in real time, compares it with the set parameters or preset mode parameters, and fine-tunes the oxygen flow rate and atomization power to ensure that the indoor oxygen concentration, humidity and hydrogen concentration remain stable within the target range for a long time.
