Description

Technical Field

[0001] This invention belongs to the field of artificial environment control and air conditioning technology, specifically relating to a building heat, humidity and oxygen supply device and method that combines active ejection evaporation and oxygen diffusion. Background Technology

[0002] The Qinghai-Tibet Plateau, a unique geographical unit on Earth, has an average altitude exceeding 4,000 meters and is characterized by extreme climate features of low oxygen, severe cold, and dryness. Related research data indicates that the atmospheric oxygen content on the plateau is far lower than at sea level, and the relative humidity in winter often falls below 30%. This extreme environment has a severe cumulative effect on human physiological functions: hypoxia leads to decreased blood oxygen saturation, causing headaches and chest tightness; extreme dryness and severe cold damage the respiratory mucosa, cause dry and cracked skin, and exacerbate the difficulty in tolerating hypoxia symptoms. Therefore, creating a comfortable indoor living environment with suitable temperature, adequate humidity, and sufficient oxygen concentration is crucial for ensuring the health of military personnel and civilians on the plateau and for the smooth implementation of various aid projects in Tibet. Currently, the control of indoor environments on the plateau mainly relies on a combination of independently operating equipment: heating through air conditioners or radiators, humidification using various humidifiers, and oxygen supply through oxygen generators or cylinders. This model has many drawbacks: First, the simultaneous operation of multiple devices not only occupies the already limited indoor space of high-altitude buildings, but also leads to complex pipelines, superimposed energy consumption, and serious noise interference; second, the lack of coordinated control among the devices often results in neglecting one aspect while focusing on another, making it impossible to achieve a precise dynamic balance of environmental parameters.

[0003] More importantly, existing technologies face irreconcilable thermodynamic contradictions when dealing with the three physical fields of heat, humidity, and oxygen: Firstly, while current air conditioning and heating technologies raise room temperature, they significantly reduce relative humidity, leading to greater indoor dryness. Secondly, conventional humidification methods mostly rely on the principle of sensible heat absorption through water evaporation, which causes a drop in room temperature while humidifying. Furthermore, reduced air density leads to a decrease in the mass flow rate of conventional fans, significantly reducing their heat dissipation and moisture exchange capabilities. At low Reynolds numbers, the diffusion performance of airflow weakens; relying solely on natural diffusion or low-pressure transport, the hot, humid, and oxygen-rich airflow easily forms significant stratification indoors, making it difficult to create a uniformly mixed and comfortable airflow field in areas where people are active. Summary of the Invention

[0004] The purpose of this invention is to overcome the limitations of heat and mass transfer caused by the low air pressure and low temperature environment of high altitude, solve the technical problems of heating causing dryness, humidification causing coldness and unsuitable oxygen supply, and provide a building heat, humidity and oxygen supply device and method that coordinates active ejection evaporation and oxygen diffusion to achieve coordinated coupling of heat, humidity and oxygen fields.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a building heat, humidity and oxygen supply device that combines active ejector evaporation and oxygen diffusion, including a water storage tank, a hot air ejector nozzle assembly, a porous media assembly, an oxygen diffusion assembly and a heating rod assembly; A porous media assembly is vertically mounted above the water storage tank. An oxygen diffusion assembly is mounted on top of the porous media assembly. The input end of the oxygen diffusion assembly is connected to an oxygen source interface. A hot air ejector nozzle assembly is located below the bottom of the porous media assembly and above the water storage tank. The input end of the hot air ejector nozzle assembly is connected to a hot air source interface. A heating rod assembly is installed inside the water storage tank. The hot air ejector nozzle assembly sprays air upwards toward the porous media assembly, and the oxygen dispersing assembly releases oxygen downwards toward the porous media assembly.

[0006] A further improvement of the present invention is that the hot air ejector nozzle assembly includes a distribution pipe and a plurality of adjustable angle ejector nozzles mounted on the distribution pipe.

[0007] A further improvement of the present invention is that porous media fixing devices are provided on both sides of the porous media assembly, and the porous media fixing devices are fixed to the water storage tank.

[0008] A further improvement of the present invention is that the oxygen diffusion assembly includes an adjustable-angle canopy with an internal space, and a gas distribution cavity is formed inside the adjustable-angle canopy.

[0009] A further improvement of the present invention is that the oxygen source interface extends into the interior of the adjustable-angle ceiling through a pipeline, and a main pipeline diffusion hole is provided on the pipeline; The bottom surface of the adjustable-angle canopy has several evenly distributed canopy diffuser holes.

[0010] A further improvement of the present invention is that the adjustable angle canopy is mounted on top of the porous media assembly via a rotating shaft mechanism.

[0011] A further improvement of the present invention is that the diameter of the main pipe diffusion hole is larger than the diameter of the ceiling diffusion hole.

[0012] A further improvement of the present invention is that the heating rod assembly includes a heating rod that extends into the interior of the water storage tank.

[0013] A further improvement of the present invention is that it also includes a control component, which is electrically connected to the heating rod assembly, the oxygen source interface and the hot air source interface.

[0014] Secondly, the present invention also provides a method for combined heat, humidity and oxygen supply in buildings that combines active ejection evaporation with oxygen diffusion, comprising the following steps: S1, the working fluid water in the water storage tank is heated by the heating rod assembly, and the porous medium assembly absorbs the heated working fluid water through capillary action to form a wet evaporation interface. S2, hot air is input to the hot air ejector nozzle assembly through the hot air source interface, and oxygen is input to the oxygen diffusion assembly through the oxygen source interface; S3, the hot air ejector nozzle assembly ejects hot air upward to impact the humidified evaporation interface formed in S1, forming an upward hot and humid airflow, while the oxygen diffusion assembly releases oxygen-rich airflow downward. S4, the rising hot and humid airflow and the oxygen-enriched airflow come into contact and mix in the porous medium component area to form a mixed airflow, which is then output to the room.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a building combined heat, moisture, and oxygen supply device that integrates active ejector evaporation and oxygen diffusion. By placing a hot air ejector nozzle assembly at the bottom of a porous media component and spraying upwards, while simultaneously placing an oxygen diffusion component at the top and releasing downwards, a counter-flow pattern is created between the rising hot and humid airflow and the descending oxygen-rich airflow. This counter-current heat exchange arrangement allows the two airflows to fully contact and undergo intense turbulent mixing in the porous media component area, fundamentally solving the problem of uneven distribution of heat, moisture, and oxygen caused by weak gas diffusion and easy stratification under low-pressure conditions at high altitudes. The hot air ejector nozzle assembly uses an active ejection method to spray high-speed airflow. Its strong momentum entrainment effect effectively overcomes the mass flow rate reduction of conventional fans caused by low-pressure conditions at high altitudes, ensuring the stability and penetration depth of the airflow, thereby enhancing the heat and mass transfer power required for moisture evaporation on the porous media surface. The porous media component is vertically mounted on the water storage tank. Utilizing capillary action, it automatically draws in liquid to form a large-area humidification and evaporation interface. Combined with the preheating of the working fluid water by the heating rod component, a significant water vapor partial pressure difference is created, enabling highly efficient humidification without an additional power source in low-temperature environments. This effectively avoids the problem of room temperature drop caused by conventional humidification methods. Ultimately, through the synergistic coupling of heat, humidity, and oxygen fields, the device simultaneously completes heating, humidification, and oxygen supply in an integrated structure. This replaces the redundant mode of traditional multi-unit independent operation, significantly saving space and energy consumption. It provides an efficient, uniform, and energy-saving indoor environmental protection solution for extreme environments such as high-altitude low-pressure, hypoxic, and frigid dry conditions.

[0016] Furthermore, the oxygen diffusion assembly includes an adjustable-angle canopy with an internal space. A gas distribution cavity is formed inside the adjustable-angle canopy. An external oxygen source interface extends into the adjustable-angle canopy through a pipeline. A main pipeline diffusion hole is opened on the pipeline to release oxygen into the cavity of the adjustable-angle canopy to establish a pressure stabilization buffer. Several evenly distributed canopy diffusion holes are opened on the bottom surface of the adjustable-angle canopy to evenly diffuse the oxygen-rich gas in the cavity downwards, forming an "oxygen shower" field.

[0017] Furthermore, the hot air ejector nozzle assembly includes a distribution pipe and several adjustable-angle ejector nozzles mounted on the distribution pipe. The adjustable-angle ejector nozzles are configured to spray obliquely upwards. This design utilizes the momentum of the high-speed hot airflow to entrain surrounding air, overcoming the attenuation of airflow under low air pressure at high altitudes. At the same time, the oblique upward spray angle prevents unevaporated condensate dripping from the porous medium above from directly dripping into the nozzle and causing blockage or damage.

[0018] This invention also provides a method for co-supplying heat, humidity, and oxygen in buildings through active ejection evaporation and oxygen diffusion. First, water is heated as the working fluid, and a humidified evaporation interface is spontaneously formed using capillary action, laying the foundation for efficient evaporation and avoiding additional power consumption. Then, hot air and oxygen are simultaneously introduced to prepare for the subsequent synergistic effect. Next, the rising hot air stream impacts the humidified interface for forced convection heat transfer and humidification, while simultaneously releasing an oxygen-rich stream downwards. This counter-current arrangement allows the two air streams to fully converge in the porous medium region, generating a strong turbulent mixing effect, effectively solving the problems of slow gas diffusion and easy stratification under low-pressure environments. The entire method integrates heating, evaporation, ejection, diffusion, and mixing processes into a coherent flow. Through the temporal coordination and spatial synergy between each step, it overcomes the contradictions of humidification and cooling and uneven oxygen supply in traditional technologies, while utilizing jet entrainment to ensure efficient airflow delivery under low-pressure environments. Ultimately, it outputs a comfortable airflow with uniform temperature, humidity, and oxygen concentration distribution, achieving efficient and energy-saving synergy of heating, humidification, and oxygen supply in an integrated manner under extreme high-altitude environments.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] In the description of the embodiments of the present invention, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0027] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings: like Figures 1 to 2 As shown, this invention provides a building combined heat, humidity, and oxygen supply device that integrates active ejector evaporation and oxygen diffusion, including an oxygen source interface 1, a hot air source interface 2, a water storage tank 3, a hot air ejector nozzle assembly 4, a porous media assembly 5, an oxygen diffusion assembly 6, and a heating rod assembly 7. The porous media assembly 5 is vertically mounted above the water storage tank 3, and the oxygen diffusion assembly 6 is positioned on top of the porous media assembly 5. The input end of the oxygen diffusion assembly 6 is connected to the oxygen source interface 1. The hot air ejector nozzle assembly 4 is located below the bottom of the porous media assembly 5 and above the water storage tank 3. The input end of the hot air ejector nozzle assembly 4 is connected to the hot air source interface 2. The heating rod assembly 7 is located inside the water storage tank 3. The jetting direction of the hot air ejector nozzle assembly 4 is upward towards the porous media assembly 5, and the release direction of the oxygen diffusion assembly 6 is downward towards the porous media assembly 5.

[0029] The water storage tank 3 forms the base of the device. Made of stainless steel, it offers good corrosion resistance and structural strength, and is used to store the working fluid, water. The porous media assembly 5 is vertically mounted above the water storage tank 3 via a capillary structure at its bottom. This assembly is made of a hydrophilic material with a high specific surface area, such as sintered metal fibers or porous ceramics, and its function is to provide a reaction interface for gas-liquid contact and mixing. The oxygen diffusion assembly 6 is fixed to the top of the porous media assembly 5 by a bracket. Its input end is connected to the oxygen source interface 1 via a pipe, which is used to connect to an external oxygen cylinder or oxygen generator. The hot air ejector nozzle assembly 4 is mounted below the bottom of the porous media assembly 5 via a support structure. Its position is higher than the water level in the water storage tank 3 to avoid interference. Its input end is connected to the hot air source interface 2 via a pipe, which is used to connect to an external hot air source, such as an electric heater or a waste heat recovery device. The heating rod assembly 7 is located inside the water storage tank 3 and is used to heat the working fluid water within the tank. The hot air ejector nozzle assembly 4 is configured to spray upwards towards the porous media assembly 5, i.e., obliquely upwards; the oxygen dispersing assembly 6 is configured to release downwards towards the porous media assembly 5, i.e., vertically or obliquely downwards. This arrangement allows the rising hot and humid airflow and the sinking oxygen-rich airflow to form a counter-current contact in the region of the porous media assembly 5. This specific structure, through the counter-current gas-liquid arrangement, effectively promotes the turbulent mixing of heat, humidity, and oxygen, overcoming the problems of weak airflow diffusion performance and easy stratification in the low-pressure environment of high altitudes, and achieving uniform and comfortable indoor environmental control.

[0030] like Figure 3 and Figure 6 As shown, porous media assembly 5 is provided with porous media fixing devices 8 on both sides, and the porous media fixing devices 8 are fixed to the water storage tank 3. Specifically, the porous media fixing device 8 can be an L-shaped groove. The vertical side of the L-shaped groove is fixedly connected to the upper edge of the side wall of the water storage tank 3 by bolt fasteners, while the horizontal side of the L-shaped groove supports and clamps the bottom edge of the porous media assembly 5. This fixing method ensures that the porous media assembly 5 maintains a stable vertical posture during device operation, which is conducive to uniform liquid absorption by capillary action. At the same time, it facilitates the disassembly, cleaning, or replacement of the porous media assembly 5, improving the maintainability of the equipment.

[0031] For example Figure 4As shown, the hot air ejector nozzle assembly 4 includes a distribution pipe and several adjustable-angle ejector nozzles 12 mounted on the distribution pipe. The adjustable-angle ejector nozzles 12 are arranged along the width direction of the porous media assembly 5, and the nozzle angle is configured to spray obliquely upwards. Each adjustable-angle ejector nozzle 12 is connected to the distribution pipe via a ball hinge or threaded structure, allowing the nozzle to be adjusted within a certain angle range. In practical applications, the angle can be adjusted to the optimal value based on the wetting area of ​​the porous media assembly 5. The adjustable angle design ensures that the high-speed hot airflow can uniformly cover the evaporation interface of the porous media assembly 5, while preventing condensate that may drip from above from directly entering the nozzle, thus ensuring the stability of the spray and extending the assembly's service life.

[0032] like Figure 7 As shown, the oxygen diffusion assembly 6 includes an adjustable-angle canopy 11 with an internal space. The adjustable-angle canopy 11 is no longer merely a baffle; it forms a gas distribution cavity, constituting the basic structure for oxygen diffusion. The oxygen source interface 1 extends into the adjustable-angle canopy 11 via a pipeline. A main pipeline diffusion hole 9 is provided on the pipeline to release oxygen into the internal cavity of the adjustable-angle canopy 11, establishing a static pressure buffer. Several evenly distributed canopy diffusion holes 10 are provided on the bottom surface of the adjustable-angle canopy 11 to evenly diffuse the oxygen-rich gas in the cavity downwards. To ensure uniform airflow distribution, the diameter of the main pipeline diffusion hole 9 is designed to be larger than the diameter of the canopy diffusion holes 10. This design ensures that the oxygen can be adequately buffered and stabilized after entering the internal cavity of the adjustable-angle canopy 11, thereby achieving a uniform downward "oxygen shower" effect through the canopy diffusion holes 10.

[0033] In this embodiment, the adjustable-angle canopy 11 is mounted on top of the porous media assembly 5 via a rotating shaft mechanism. The rotating shaft mechanism includes a fixed shaft and a bearing seat. The fixed shaft is mounted on a support frame at the top of the device, while the bearing seat is fixed to the back of the adjustable-angle canopy 11. Through this rotating shaft mechanism, the adjustable-angle canopy 11 can be rotated and adjusted within a certain angle range around a horizontal axis. This structure allows the tilt angle of the adjustable-angle canopy 11 to be adjusted, enabling flexible guidance of the outflow direction of the mixed airflow according to the indoor spatial layout and the area of ​​human activity, thus optimizing the delivery accuracy of comfortable airflow.

[0034] like Figure 5As shown, the thermal and humidity self-balancing system of this device consists of a heating rod assembly 7 and a water storage tank 3 forming a closed loop. The heating rod assembly 7 includes a heating rod 13 that extends into the interior of the water storage tank 3. The heating rod 13 is an electric heating tube type, which is horizontally inserted into the interior of the water storage tank 3 through a sealed interface on the side wall of the water storage tank 3 and is immersed in the working fluid water. This direct immersion heating method has high thermal efficiency and can quickly heat the water to the preset temperature. The device also includes a water circulation mechanism for transporting the preheated warm water from the water storage tank 3 to the top of the porous media component 5 for wetting. The heating rod assembly 7 works in conjunction with the water circulation mechanism to heat the water in the water storage tank 3 to a preset temperature of 40-50°C and wet the porous media component 5, making the water vapor partial pressure on the surface of the porous media component 5 significantly higher than that of the flowing hot air. This utilizes the huge enthalpy difference to achieve efficient humidification in a low-temperature environment.

[0035] In this embodiment, the device further includes a control component, which is electrically connected to the heating rod assembly 7, the oxygen source interface 1, and the hot air source interface 2. Specifically, the control component can be an integrated control panel or a separate multiplexer. In practical applications, the control component is electrically connected via cables to the power circuit of the heating rod assembly 7, the solenoid valve installed on the oxygen source interface 1 pipeline, and the solenoid valve installed on the hot air source interface 2 pipeline, thereby achieving independent control of heating, oxygen supply, and hot air supply.

[0036] Based on the aforementioned control connections, when the hot and humid airflow at the top of the device condenses and liquefies during heat exchange, the droplets fall back into the water storage tank 3 along the porous media component 5. According to the system's operating status, the control component uses the heating rod 13 to reheat the collected condensate to the operating temperature. The resulting water vapor, under the entrainment effect of the low-humidity hot air jet at the bottom, participates again in the wetting cycle of the porous media component 5 through the water circulation mechanism. This heat and humidity self-balancing mechanism transforms the traditional "waste liquid discharge" into "energy recovery," effectively preventing overflow from the water storage tank 3 and significantly reducing dependence on external humidification water sources, achieving dynamic water balance during long-term operation of the device.

[0037] Based on the aforementioned precise control capability over a single process, this control component can independently control the opening and closing of the valves corresponding to the heating rod assembly 7, the external hot air source, and the external oxygen source. This enables centralized and independent regulation of the three media—water (indirectly controlled by the heating rod), air (hot air), and oxygen—allowing the device to switch between different operating modes and achieve intelligent operation and energy-saving regulation with "one machine for multiple uses." Specifically, it includes the following five operating modes: Mode 1 (Heated Humid Air Mode): When the indoor temperature and relative humidity The indoor environment is dry and cold, typically occurring during the initial cold start phase in winter, when the demand for both heat and humidity is extremely high. The user issues commands through the control component, or the control component automatically connects the power supply to the external hot air source and heating rod assembly 7 based on sensor signals, while simultaneously keeping the oxygen supply pipeline valve closed. At this time, the hot air ejector nozzle assembly 4 continuously sprays low-humidity hot air upwards. This airflow, upon passing through the porous media assembly 5 preheated to 40-50℃, undergoes a vigorous heat and moisture exchange with the wet film surface, rapidly absorbing moisture and transforming it into a high-temperature, high-humidity airflow that is then delivered into the room, achieving both heating and humidification.

[0038] Mode 2 (Humidity and Oxygen Supply Mode): When the indoor temperature... relative humidity This range typically occurs in scenarios where basic heating (such as underfloor heating) is already in place, but the air is dry and the human body is sensitive to oxygen demand. The user or control system issues a command to open the oxygen supply valve and the water circulation heating system, while keeping the hot air ejector nozzle assembly closed. The heating rod assembly 7 heats the working fluid water in the water storage tank 3 and maintains it at 50-60℃, with the circulating warm water continuously wetting the porous media assembly 5. Without bottom forced convection air interference, due to the large water vapor partial pressure difference, a high-concentration warm water vapor diffusion layer naturally forms around the porous media on the heated wet film surface, generating weak natural convection and rising moisture. Without the obstruction and dilution of the high-speed hot air from the bottom, the descending oxygen-enriched airflow slowly passes through or skims over the porous media assembly 5 surrounded by warm water vapor under the influence of gravity. At this time, dry oxygen molecules and high-density water vapor molecules undergo sufficient mass diffusion and gradually transform into high-humidity oxygen-enriched clusters that diffuse into the environment, achieving a humidifying and high-oxygen effect.

[0039] Mode 3 (Simple Humidification Mode): When the indoor temperature... But relative humidity This range is commonly seen in the "hot dryness" phenomenon caused by excessive heating in high-altitude areas. Introducing hot air in this situation would exacerbate the stuffiness indoors. Therefore, it is suitable for situations where the indoor temperature has reached the standard and the oxygen content meets basic requirements, but the relative humidity is severely low, and the user only needs to increase the indoor humidity. The user or control system issues a command to turn on the water circulation heating system, while keeping the hot air ejector nozzle assembly 4 and oxygen diffusion assembly 6 in the off state. The heating rod assembly 7 starts working, heating the working fluid water in the water storage tank 3 and maintaining it at a constant temperature of 55-65℃. The circulating water pump delivers hot water to the top and continuously wets the porous media assembly 5, causing it to form a high-temperature water film on its large specific surface area. Since the hot air ejector nozzle assembly 4 and oxygen diffusion assembly 6 are not turned on at this time, the inside of the device is in a static flow field without forced convection. A significant water vapor partial pressure difference is generated between the high-temperature water film on the surface of the porous media assembly 5 and the surrounding static dry air. Driven by this partial pressure difference, liquid water molecules undergo violent natural evaporation and molecular diffusion, transforming into gaseous water vapor. The generated high-temperature water vapor, being less dense than the surrounding cold air, creates a weak natural buoyancy. Under this buoyancy, the hot, humid air naturally rises above the top of the device and gradually diffuses into the room via Brownian motion, effectively alleviating the dry environment.

[0040] Mode 4 (Simple Oxygen Supply Mode): When the indoor temperature... relative humidity Furthermore, the indoor personnel density is relatively high, such as in a conference room. Within this parameter range, both temperature and humidity are within a comfortable range; the only environmental drawback is low air pressure and oxygen deficiency. By controlling the components to cut off the power to the external hot air source and heating rod assembly 7, only the valve on the oxygen supply pipeline is opened. At this time, the device stops the heat and humidity treatment function, and only the oxygen diffusion assembly 6 at the top evenly diffuses and releases an oxygen-enriched flow downwards. Utilizing the physical property that oxygen is denser than air, the oxygen-enriched flow naturally sinks without active hot air interference, forming a high-concentration "oxygen bath" area in the personnel activity area below the device, meeting the personnel's oxygen intake needs, and this mode has extremely low energy consumption.

[0041] Mode 5 (Heat, Humidity, and Oxygen Combined Supply Mode): When the indoor temperature... relative humidity This area falls within the most common "sub-comfort transition zone" in high-altitude areas, where the human body feels slightly cold, somewhat dry, and experiences persistent hypoxia. To address the extreme combination of hypoxia, cold, and dryness common in high-altitude regions, the user issues commands through the control components, simultaneously activating the external hot air source, heating rod assembly 7, and oxygen supply valve. At this time, the hot air ejector nozzle assembly 4 sprays a low-humidity airflow of 50-60°C upwards at high speed. This airflow impacts and penetrates the porous media assembly 5, which is continuously wetted with preheated working fluid water at approximately 40°C. Due to the significant water vapor partial pressure difference between the high-temperature dry air and the warm water surface, the liquid water rapidly vaporizes (absorbing latent heat), and the airflow completes a near-isoenthalpic humidification process in a very short time, transforming into a high-temperature, high-humidity rising buoyant flow. Simultaneously, the oxygen diffusion assembly 6 at the top diffuses and releases a lower-temperature, oxygen-enriched flow downwards. The rising hot, humid airflow and the descending cold, oxygen-enriched flow form a countercurrent in the porous media assembly 5 area, resulting in intense collision and turbulent mixing. After sufficient heat and mass exchange, the oxygen is preheated and humidified, and the hot and humid airflow is moderately cooled and mixed with oxygen, ultimately forming a composite comfortable airflow with uniform temperature and humidity distribution and qualified oxygen concentration. This mixed airflow is concentrated and transported to the indoor activity area by the guiding effect of the adjustable-angle ceiling 11, realizing comprehensive, coordinated and efficient control of the extreme plateau environment.

[0042] It should be noted that the above modes are only the main modes. Users can set other working modes separately according to different personnel and environmental needs.

[0043] This invention also provides a method for combined heat, humidity and oxygen supply in buildings that integrates active ejection evaporation and oxygen diffusion, comprising the following steps: S1, the working fluid water in the water storage tank 3 is heated by the heating rod assembly 7, and the porous medium assembly 5 absorbs the heated working fluid water through capillary action to form a moist evaporation interface. S2, hot air is input to the hot air ejector nozzle assembly 4 through the hot air source interface 2, and oxygen is input to the oxygen diffusion assembly 6 through the oxygen source interface 1. S3, the hot air ejector nozzle assembly 4 ejects a stream of hot air upward to impact the humidified evaporation interface formed in S1, forming an upward hot and humid airflow, while the oxygen diffusion assembly 6 releases an oxygen-rich stream downward. S4, the rising hot and humid airflow and the oxygen-enriched airflow come into contact and mix in the region of the porous medium component 5 to form a mixed airflow, which is then output to the room.

[0044] In step S1, the heating rod assembly 7 heats the working fluid water in the water storage tank 3 to 40-50°C. Simultaneously, the porous media assembly 5, utilizing its hydrophilicity and capillary action, continuously draws the heated working fluid water from the water storage tank 3, forming a water film on its large specific surface area, i.e., a humidified evaporation interface. In step S2, low-humidity hot air at approximately 50-60°C, supplied by an external hot air source, is introduced into the hot air ejector nozzle assembly 4 through the hot air source interface 2; simultaneously, oxygen-enriched gas supplied by an external oxygen source is introduced into the oxygen diffusion assembly 6 through the oxygen source interface 1. These two input processes can occur simultaneously. In step S3, the hot air ejector nozzle assembly 4 ejects a high-speed hot air stream upwards, which directly impacts the humidified evaporation interface formed on the surface of the porous media assembly 5 in step S1. Due to the significant water vapor partial pressure difference between the high-temperature airflow and the warm water interface, the moisture is rapidly evaporated, the airflow is humidified and moderately cooled, forming a buoyant rising hot and humid airflow. At the same time, the oxygen diffusion assembly 6 uniformly releases a lower-temperature oxygen-enriched stream downwards. In S4, the rising hot and humid airflow meets the descending cold and oxygen-rich airflow in the space containing the porous media component 5. Due to the difference in flow velocity and temperature, strong turbulent mixing occurs. The oxygen is preheated, and the hot and humid airflow is moderately cooled and diluted, ultimately forming a mixed airflow with uniform temperature, humidity, and oxygen concentration. This mixed airflow is then transported to the indoor personnel activity area by the guide components at the top of the device. This method, through orderly steps, synergistically utilizes ejector evaporation and oxygen diffusion technologies, effectively solving the technical challenge of coordinating and efficiently operating heating, humidification, and oxygen supply in high-altitude environments.

[0045] Based on the above embodiments, the present invention also provides two derivative simplification devices for modular reduction in specific application scenarios. For details, please refer to the provided text. Figure 8 and Figure 9 .exist Figure 8 In the illustrated embodiment, the heating rod assembly 7 within the water storage tank is removed; the remaining structure and airflow organization logic remain consistent with the embodiments described above. During device operation, the porous media assembly 5 is wetted using room-temperature working fluid water. At this time, the device primarily relies on forced convection of the airflow for mass transfer. This configuration is suitable for oxygen-deficient environments with low or even low heat load requirements, but rigid requirements for relative humidity and oxygen content. This structure achieves the "oxygenation and humidification" function with lower energy consumption and avoids the problem of excessive temperature rise during oxygen supply in summer. Figure 9 In the illustrated embodiment, the top oxygen diffusion assembly 6 is removed, leaving only the bottom hot air ejector nozzle assembly 4 and the water circulation heating system. The device focuses on using a dual heat source of "hot air + hot water" to drive the evaporation of moisture from the porous medium surface. This configuration is suitable for situations where indoor oxygen levels are acceptable, but there are extremely high requirements for increasing indoor temperature and humidity. Utilizing the unique ejector and thermal compensation technology of this invention, this structure can be used independently as a highly efficient "non-insulated humidifier and heater."
