Description

Technical Field

[0001] This utility model relates to the field of integrated air conditioning technology, specifically an integrated air conditioning unit for oxygen chambers. Background Technology

[0002] An oxygen chamber is a device with a sealed space that provides a specific gaseous environment for users by regulating parameters such as internal oxygen concentration, pressure, and temperature. It is widely used in medical rehabilitation, health care, and other scenarios. Its core function is to ensure the user's oxygen safety and comfort through a stable internal environment.

[0003] The operation of existing oxygen chambers relies on the coordinated work of multiple key systems, such as the oxygen supply system, air conditioning system, and pressurization system: The air conditioning system is mainly responsible for regulating the temperature inside the chamber, achieving heat exchange through refrigerant circulation, and maintaining a suitable temperature inside the chamber; The oxygen supply system generates oxygen through oxygen generators and delivers it to the chamber through pipelines to meet the oxygen needs of users; The pressurization system compresses outside air through air compression equipment and sends it into the chamber to maintain the required air pressure inside the chamber and ensure the pressure stability of the closed environment.

[0004] The existing oxygen chambers have poor system integration. The air conditioning system, oxygen supply system, and pressurization system all need to be arranged separately. The independence of the three systems not only results in a large system space occupation, but also increases the complexity of system installation and maintenance. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an integrated oxygen chamber air conditioning unit to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated oxygen chamber air conditioning unit, comprising an integrated unit body, wherein an air conditioning compressor, an air conditioning condenser, an air conditioning fan, two radiators, and an oxygen-generating molecular sieve are respectively installed at the lower part of the integrated unit body, and an oxygen-generating molecular sieve is connected to the back of the oxygen-generating molecular sieve; a compressed air pipe is connected to one side of one of the radiators; a sealed water tank is installed on one side of the integrated unit body, and an evaporator pipe and a temperature regulating pipe are respectively connected inside the sealed water tank; an outlet pipe and a return pipe are respectively connected to one side of the sealed water tank; two oil-water filters are installed on the back of the sealed water tank; a soundproof cover is connected to the other side of the integrated unit body, and an air compressor and an oxygen-generating compressor are respectively installed inside the soundproof cover; a pre-filter is connected to the air inlet of both the air compressor and the oxygen-generating compressor, and an automatic pressure relief valve is connected to the air outlet of both the air compressor and the oxygen-generating compressor; a cooling fan is installed on one side of the soundproof cover.

[0007] By adopting the above technical solution, the core components of the air conditioning system, pressurization system, and oxygen supply system required for the oxygen chamber can be integrated into the main body of the unit, eliminating the need for separate layout of the three systems, significantly reducing the overall space occupied by the system, and at the same time realizing the basis for the coordinated operation of each system. The air conditioning system relies on the air conditioning compressor, air conditioning condenser, sealed water tank, and evaporator to build a dual-cycle cooling and heating structure. The pressurization system ensures clean and stable pressurized air through the air compressor, oil-water filter, and radiator. The oxygen supply system provides clean oxygen supply through the oxygen generating compressor, oxygen generating molecular sieve, and temperature regulating pipe. The soundproof cover and cooling fan provide sound insulation and heat dissipation guarantee for the operation of the compressor. Structurally, this solves the problems of the existing oxygen chamber system being scattered and complex to install and maintain.

[0008] Furthermore, a third air inlet is provided on the outer surface of the main body of the integrated unit, and the position of the third air inlet corresponds to the position of the two radiators. First air inlets are provided on both sides and the bottom of the main body of the integrated unit, and the first air inlets correspond to the sides and the bottom of the air conditioner condenser, respectively. A second air inlet is provided on the upper side of one side of the main body of the integrated unit, and the position of the second air inlet corresponds to the position of the sound insulation cover. A first air outlet and a second air outlet are provided on the back of the main body of the integrated unit, and the position of the first air outlet corresponds to the position of the air conditioner fan, and the position of the second air outlet corresponds to the position of the cooling fan.

[0009] By adopting the above technical solution, each air inlet and outlet is precisely matched to the corresponding functional component: the third air inlet introduces cooling airflow to the radiator, the first air inlet supplies cooling air to the air conditioner condenser, the second air inlet supplements the compressor inside the soundproof enclosure, the first air outlet discharges the cooling airflow from the air conditioner condenser, and the second air outlet discharges the cooling air inside the soundproof enclosure; this precise airflow path design can avoid mutual interference between airflows of different functions, reduce air resistance loss, ensure that each component requiring heat dissipation can obtain sufficient and stable cooling airflow, improve overall heat dissipation efficiency, and ensure stable system operation.

[0010] Furthermore, the air conditioner compressor, air conditioner condenser, and evaporator are connected by an expansion valve, a four-way valve, and pipes.

[0011] By adopting the above technical solutions, the expansion valve can reduce the pressure of the medium-temperature, high-pressure refrigerant cooled by the air conditioner condenser to a low-temperature, low-pressure state, meeting the refrigerant's need for heat absorption and evaporation in the evaporator tube; the four-way valve can switch the refrigerant circulation direction, allowing the system to flexibly switch between cooling and heating modes. In summer cooling, the refrigerant circulates through the air conditioner compressor, air conditioner condenser, expansion valve, evaporator tube, and air conditioner compressor. In winter heating, the four-way valve reverses the flow, allowing the refrigerant to directly enter the evaporator tube and exchange heat with the cooling water, thereby meeting the oxygen chamber's temperature control needs in different seasons and improving the equipment's applicability.

[0012] Furthermore, the two automatic pressure relief valves are connected to two oil-water filters via pipes, and the two oil-water filters are connected to two radiators via channels. The other radiator is connected to a temperature control pipe via a pipe, and one end of the temperature control pipe is connected to an oxygen-generating molecular sieve via a pipe.

[0013] By adopting the above technical solutions, a stable transmission path for the pressurization and oxygen supply system is established: the automatic pressure relief valve can monitor the compressed air pressure in real time, and automatically release pressure when the pressure exceeds the set value to avoid overpressure damage to equipment or affecting the stability of the oxygen chamber pressure; the oil-water filter can filter out oil and water in the compressed air to prevent oil and water from contaminating the oxygen chamber air or clogging the oxygen-generating molecular sieve; the radiator can cool the compressed air to prevent high-temperature air from entering the oxygen chamber and causing temperature fluctuations inside the chamber; the temperature regulating pipe can further exchange heat between the compressed air used for oxygen generation and the cooling water in the sealed water tank, so that the temperature of the generated oxygen is closer to the temperature inside the oxygen chamber, ensuring that the pressurized air is clean and stable, the oxygen temperature is suitable, and the environmental parameters inside the oxygen chamber are stable.

[0014] Furthermore, the inner wall of the soundproof enclosure is lined with sound-insulating felt, and shock absorbers are installed at the bottom of the air conditioning compressor, air compressor, and oxygen compressor.

[0015] By adopting the above technical solutions, the sound-absorbing felt on the inner wall of the soundproof enclosure can effectively absorb the noise generated by the air compressor and oxygen compressor during operation, reduce the outward transmission of noise, and reduce the noise interference of the equipment operation to the surrounding environment; the shock absorbers at the bottom of the air conditioning compressor, air compressor and oxygen compressor can buffer the vibration generated during equipment operation, on the one hand, to prevent the vibration from causing the internal parts of the equipment to loosen or be damaged, and extend the service life of the parts, and on the other hand, to reduce the vibration transmitted to the main body of the integrated machine, improve the overall operating stability of the equipment, and indirectly reduce the additional noise caused by vibration.

[0016] Furthermore, the air compressor and the oxygen compressor are arranged vertically in parallel.

[0017] By adopting the above technical solution, the air compressor and oxygen compressor are arranged in a vertically parallel manner, which can make full use of the vertical space inside the integrated machine and avoid the two compressors occupying too much horizontal space when placed side by side. This makes the internal structure of the integrated machine more compact and reasonable, and allows for the integrated installation of more core components within the limited main body space, further improving the integration level of the equipment and reducing the overall footprint of the equipment.

[0018] Furthermore, four omnidirectional brake casters are connected to the bottom sides of the main body of the integrated machine, and the four omnidirectional brake casters are distributed in a rectangular array.

[0019] By adopting the above technical solution, the four omnidirectional brake casters arranged in a rectangular array not only have flexible mobility, allowing the integrated unit to be easily transported to the installation position around the oxygen chamber without the need for large handling equipment, thus reducing the difficulty of position adjustment during installation; but also can fix the equipment in the designated position through the braking mechanism, preventing the equipment from shifting due to vibration or external force during operation, and ensuring the stability of the connection pipeline between the equipment and the oxygen chamber; at the same time, during later maintenance, the brakes can be released to quickly move the equipment, improving the convenience of maintenance.

[0020] Furthermore, a touch screen is installed on the top of the all-in-one machine body, a control cabinet is installed inside the upper part of the all-in-one machine body, and a leakage current protector is installed on one side of the control cabinet.

[0021] By adopting the above technical solutions, the touch screen provides staff with an intuitive and convenient operating interface, which can set and adjust parameters such as air conditioning temperature, oxygen chamber pressure, and oxygen concentration in real time without the need to operate each system controller separately; the control cabinet, as the core control unit, can coordinate the operation rhythm of the air conditioning, pressurization, and oxygen supply systems to ensure that each system operates synchronously according to the oxygen chamber's needs; the leakage current protector can monitor the status of the equipment's power lines in real time, and will automatically trip and cut off the power supply immediately when a leakage fault occurs, avoiding electric shock accidents or equipment damage caused by leakage, and providing safety assurance for equipment operation and personnel operation.

[0022] Furthermore, both the evaporator tube and the temperature control tube are spiral-shaped, and both are made of titanium.

[0023] By adopting the above technical solution, the spiral structure can significantly increase the contact area between the evaporator tube, the temperature regulating tube, and the cooling water in the sealed water tank, prolonging the heat exchange time between the refrigerant or compressed air and the cooling water, significantly improving the heat exchange efficiency. The evaporator tube can more fully absorb the heat from the cooling water to achieve refrigerant evaporation, and the temperature regulating tube can more accurately regulate the temperature of the compressed air used for oxygen production. The titanium tube material has excellent corrosion resistance, which can prevent the evaporator tube and the temperature regulating tube from rusting due to long-term contact with the cooling water, extend the service life of the components, ensure long-term stable heat exchange effect, and reduce the frequency of maintenance and replacement.

[0024] Furthermore, the heat sink consists of a copper serpentine tube, densely distributed heat dissipation fins, and an axial fan, with the densely distributed heat dissipation fins connected to the outside of the serpentine copper tube and the axial fan mounted on the outer surface of the heat dissipation fins.

[0025] By adopting the above technical solution, the copper serpentine tube has excellent thermal conductivity, which can quickly transfer heat from the compressed air. The serpentine structure can extend the residence time of the compressed air in the tube, ensuring that the heat is fully released. The densely distributed heat dissipation fins can further expand the heat dissipation area, quickly diffusing the heat transferred by the copper serpentine tube into the air. The axial fan can generate forced airflow, accelerating the airflow through the heat dissipation fins and quickly carrying away the heat. The synergistic effect of the three can achieve efficient cooling of the compressed air, ensuring that the temperature of the pressurized air entering the oxygen chamber meets the requirements of the compressed air before oxygen production, and avoiding the impact of high-temperature air on the temperature stability inside the oxygen chamber.

[0026] In summary, the present invention has the following main advantages: 1. This utility model, through the arrangement of an air conditioning compressor, air conditioning condenser, air conditioning fan, sealed water tank, evaporator, outlet pipe, and return pipe, ensures that during cooling, the refrigerant flow path of the outdoor unit is through the air conditioning compressor, air conditioning condenser, and evaporator, while the air conditioning fan generates airflow to dissipate heat from the condenser. Meanwhile, the cooling water flow path of the indoor unit within the oxygen chamber is through the sealed water tank, outlet pipe, external water pump, indoor unit, and return pipe. The cooling water exchanges heat with the evaporator in the sealed water tank, causing the refrigerant to absorb heat and evaporate before returning to the air conditioning compressor. The cooling water, due to heat absorption, transforms into low-temperature cooling water, which then enters the evaporator of the indoor unit, absorbs heat, evaporates, and returns to the sealed water tank. The reason for using cooling water instead of refrigerant in the indoor unit is to enhance safety, preventing refrigerant leakage within the oxygen chamber and the associated fire or suffocation hazards. Furthermore, integrating the outdoor unit system into a single unit improves the overall integration of the oxygen chamber system. 2. This utility model incorporates a pre-filter, air compressor, automatic pressure relief valve, oil-water filter, radiator, and compressed air pipe. The air compressor draws in outside air through the pre-filter and a second air inlet. During this process, the pre-filter reduces dust ingress. The air compressor then delivers pressurized compressed air to the automatic pressure relief valve and oil-water filter. When the air pressure is too high, the automatic pressure relief valve begins to release pressure, and the oil-water filter removes oil and water from the compressed air, improving its cleanliness and reducing contamination of the oxygen chamber. The radiator then significantly reduces the heat of the pressurized compressed air, minimizing temperature fluctuations caused by high-temperature, high-pressure air entering the oxygen chamber. Finally, the pressurized compressed air enters the oxygen chamber through the compressed air pipe and the pressurization pipeline within the oxygen chamber, achieving the pressurization effect. Integrating the air pressure system into a single unit improves the overall integration of the oxygen chamber system. 3. This utility model incorporates a pre-filter, an oxygen compressor, an automatic pressure relief valve, an oil-water filter, a radiator, a temperature control pipe, an oxygen molecular sieve, and an oxygen pipe. The oxygen compressor draws in outside air through the pre-filter and a second air inlet. During this process, the pre-filter reduces dust ingress. The oxygen compressor delivers compressed air for oxygen production to the automatic pressure relief valve and the oil-water filter. When the air pressure is too high, the automatic pressure relief valve begins to release pressure, and the oil-water filter removes oil and water from the compressed air, improving the cleanliness of the compressed air for oxygen production and reducing stress on the oxygen molecular sieve and oxygen pipe. The system addresses air pollution within the chamber by significantly reducing the heat of the compressed air used for pressurization via a radiator. A temperature control pipe facilitates heat exchange between the oxygen-generating compressed air and the cooling water in the sealed water tank, bringing the temperature of the subsequent oxygen closer to the air conditioning temperature. This reduces the likelihood of large temperature fluctuations within the oxygen chamber caused by oxygen entering. The compressed air then passes through an oxygen-generating molecular sieve to separate nitrogen and other gases. Finally, oxygen enters the oxygen chamber through oxygen pipes and internal oxygen channels, achieving the desired oxygen supply. Integrating the oxygen supply system into a single unit enhances the overall integration of the oxygen chamber system. 4. This utility model reduces the noise transmitted outwards during the operation of the air compressor and oxygen generator by setting up a soundproof cover and a cooling fan. At the same time, the cooling fan generates airflow, drawing in outside air and air from inside the main body of the integrated unit into the soundproof cover and then expelling it through the cooling fan and the second air outlet. Although this will have some impact on the sound insulation effect, it reduces the risk of overheating of the air compressor and cooling fan operating in a closed environment. Furthermore, since the integrated unit is an outdoor unit, the slight reduction in sound insulation will not have a significant impact on the rest and training of personnel inside the oxygen chamber; thus reducing some noise transmission.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] Example 1:

[0032] Oxygen chamber air conditioning unit, such as Figures 1-8As shown, the system includes an integrated main unit 1. Inside the main unit 1, at its lower part, are installed an air conditioning compressor 4, an air conditioning condenser 5, an air conditioning fan 6, two radiators 22, and an oxygen-generating molecular sieve 23. An oxygen pipe 24 is connected to the back of the oxygen-generating molecular sieve 23. A compressed air pipe 25 is connected to one side of one of the radiators 22. A sealed water tank 9 is installed on one side inside the main unit 1. An evaporator pipe 10 and a temperature regulating pipe 19 are connected inside the sealed water tank 9. Both the evaporator pipe 10 and the temperature regulating pipe 19 are spiral-shaped and made of titanium. The air conditioning compressor 4, the air conditioning condenser 5, and the evaporator pipe 10 are connected via an expansion valve, a four-way valve, and pipes. A water outlet pipe 11 and a water return pipe 12 are connected to one side of the sealed water tank 9. Two oil-water filters 26 are installed on the back of the sealed water tank 9. The two oil-water filters 26 are connected to the two radiators 22 via channels. The other radiator 22... 2. The system is connected to the temperature control pipe 19 via a pipe. One end of the temperature control pipe 19 is connected to the oxygen-generating molecular sieve 23 via a pipe. A soundproof cover 13 is connected to the other side of the main body 1 of the integrated machine. The inner wall of the soundproof cover 13 is covered with soundproof felt. An air compressor 14 and an oxygen-generating compressor 15 are installed inside the soundproof cover 13. The air compressor 14 and the oxygen-generating compressor 15 are arranged parallel to each other. Shock absorbers are installed at the bottom of the air conditioning compressor 4, the air compressor 14 and the oxygen-generating compressor 15. A pre-filter 16 is connected to the air inlet of the air compressor 14 and the oxygen-generating compressor 15. An automatic pressure relief valve 17 is connected to the air outlet of the air compressor 14 and the oxygen-generating compressor 15. The two automatic pressure relief valves 17 are connected to two oil-water filters 26 via pipes. A cooling fan 18 is installed on one side of the soundproof cover 13. The air conditioning system, pressurization system and oxygen supply system are integrated into one machine, which effectively reduces the space occupied. The main body 1 of the all-in-one unit has a third air inlet 27 on its outer surface, which corresponds to the position of the two radiators 22. The main body 1 of the all-in-one unit has a first air inlet 7 on both sides and the bottom, which corresponds to the sides and the bottom of the air conditioner condenser 5, respectively. The main body 1 of the all-in-one unit has a second air inlet 20 on the upper side of one side, which corresponds to the position of the sound insulation cover 13. The main body 1 of the all-in-one unit has a first air outlet 8 and a second air outlet 21 on its back, which corresponds to the position of the air conditioner fan 6 and the position of the cooling fan 18. The air inlets and outlets are scientifically distributed to reduce air resistance and conflict between hot and cold air.

[0033] See Figure 1 and Figure 3In the above embodiment, a touch screen 3 is installed on the top of the all-in-one machine body 1, and a control cabinet 2 is installed inside the upper part of the all-in-one machine body 1. A leakage current protector 28 is installed on one side of the control cabinet 2. The operator can operate and control the machine through the touch screen 3 on the top. The control cabinet 2 inside the upper part of the all-in-one machine body 1 coordinates the operation rhythm of each system. At the same time, the leakage current protector 28 on one side of the control cabinet 2 monitors the power consumption status in real time. When leakage occurs, it will automatically trip to reduce the risk of leakage and provide a safe foundation for the overall operation.

The copper tube has good thermal conductivity and is serpentine to extend the residence time of compressed air. Together with the densely distributed heat dissipation fins, it increases the heat dissipation area, and the axial fan generates airflow for forced air cooling.

[0037] Example 3:

[0038] Based on the above embodiment one, the following settings are now implemented to facilitate handling, assembly, and maintenance.

[0039] See Figures 1-4 In the above embodiment, four universal brake casters are connected to the bottom sides of the main body 1 of the integrated machine. The four universal brake casters are arranged in a rectangular array and can be moved to the periphery of the oxygen chamber to assemble pipelines and run after maintenance. The machine can also be moved by the bottom universal brake casters.

[0040] The implementation principle of this utility model is as follows: First, this all-in-one machine integrates three major systems into the main body 1. Operators can operate and control it through the touch screen 3 on the top. The control cabinet 2 inside the main body 1 coordinates the operation rhythm of each system. At the same time, the leakage protection device 28 on one side of the control cabinet 2 monitors the power status in real time. When leakage occurs, it will automatically trip to reduce the risk of leakage and provide a safe foundation for overall operation. After the all-in-one machine is started, the air conditioning system, pressurization system, and oxygen supply system operate in coordination according to the temperature, pressure and oxygen concentration requirements in the oxygen chamber. The auxiliary structures such as sound insulation, heat dissipation and vibration reduction play their roles simultaneously. The specific process is as follows. The air conditioning system employs a dual-circulation mode, where refrigerant circulates within the integrated unit 1, while cooling water circulates between the integrated unit 1 and the oxygen chamber air conditioning unit. This dual circulation ensures effective cooling while mitigating safety hazards. The air conditioning compressor 4, located at the bottom of the integrated unit 1, starts, compressing the refrigerant to a high-temperature, high-pressure state before delivering it to the adjacent air conditioning condenser 5. Simultaneously, the air conditioning fan 6 next to the condenser 5 operates, generating airflow. This airflow enters through the first air inlet 7, passes through the condenser 5, and exits through the first air outlet 8, rapidly carrying away heat from the refrigerant and cooling it within the condenser. In the medium-temperature, high-pressure state, the cooled refrigerant is converted to a low-temperature, low-pressure state by the expansion valve and then transported to the evaporator tube 10 in the sealed water tank 9. The evaporator tube 10 adopts a spiral titanium tube design, which can maximize the contact area with the cooling water in the water tank and improve the heat exchange efficiency. The refrigerant absorbs heat from the cooling water here, evaporates to a medium-high temperature, low-pressure state, and finally flows back to the air conditioning compressor 4 to complete the refrigerant cycle. If it is in heating operation, the high-temperature, high-pressure refrigerant output by the air conditioning compressor 4 is switched through a four-way valve to directly enter the evaporator tube 10 to exchange heat with the cooling water, which is the same as the heating principle of existing air conditioning technology. The cooling water in the sealed water tank 9 is cooled down because the heat is absorbed by the refrigerant. The low-temperature cooling water is delivered to the air conditioning unit in the oxygen chamber through the outlet pipe 11 on one side of the sealed water tank 9 to cool the air in the oxygen chamber. The cooling water that has absorbed heat and heated up flows back to the sealed water tank 9 through the return pipe 12 to form a cooling water circulation. If it is for heating, the air in the oxygen chamber is heated up. In this process, cooling water is used to replace the refrigerant and enter the oxygen chamber directly, which completely avoids the risk of fire or suffocation caused by refrigerant leakage. To ensure stable air pressure within the oxygen chamber, the air compressor 14 starts, drawing in outside air through the pre-filter 16 at the intake end and the second air inlet 20. The pre-filter 16 filters dust and impurities from the air, reducing clogging of subsequent components and contamination of the air within the oxygen chamber. The air compressor 14 compresses the intake air into high-pressure air, which is then delivered to the automatic pressure relief valve 17 at the outlet end. If the air pressure exceeds the set value, the automatic pressure relief valve 17 will automatically open to release pressure, ensuring stable air pressure and reducing the risk of overpressure damage to the integrated unit. The regulated high-pressure air then enters one of the oil-water filters 2 through a pipeline. 6. Filter out oil and moisture from the compressed air to further improve air cleanliness; then pressurize the air and direct it to one of the radiators 22. The radiator 22 consists of a copper serpentine tube, dense heat dissipation fins, and an axial fan. After the axial fan starts, it draws air through the third air inlet 27 to generate airflow. The heat is quickly carried away by the heat dissipation fins from the high-pressure air in the copper serpentine tube, and the airflow is then discharged from the first air outlet 8, reducing the temperature fluctuations in the oxygen chamber caused by hot air entering the chamber; finally, the cooled clean high-pressure air is delivered to the oxygen chamber through the compressed air pipe 25 on one side of the radiator 22 to complete the pressurization. To ensure a stable oxygen supply to the oxygen chamber, the oxygen compressor 15 starts, drawing in outside air through the pre-filter 16 and the second air inlet 20. After the pre-filter 16 filters out dust, the oxygen compressor 15 compresses the air into high-pressure air for oxygen production. This high-pressure air then passes through the automatic pressure relief valve 17 for pressure stabilization before entering the oil-water filter 26 to remove oil and water, reducing contamination of the oxygen-generating molecular sieve 23 or the generated oxygen. The filtered high-pressure air first flows to the radiator 22 for initial cooling, then is delivered to the temperature-regulating pipe 19 in the sealed water tank 9. The temperature-regulating pipe 19, also a spiral titanium pipe, fully exchanges heat with the cooling water in the sealed water tank 9, ensuring the high-pressure air temperature is close to the cooling water temperature of the air conditioning system, reducing temperature fluctuations inside the oxygen chamber after the oxygen enters. The temperature-regulated high-pressure air then enters the oxygen-generating molecular sieve 23, which separates impurities such as nitrogen from the air, generating high-purity oxygen. Finally, the oxygen is delivered to the oxygen chamber through the oxygen pipe 24 on the back of the molecular sieve 23, thus achieving oxygen supply. During operation of the integrated unit, the sound-insulating felt pasted on the inner wall of the soundproof cover 13 can effectively block the noise generated by the air compressor 14 and the oxygen compressor 15. At the same time, the cooling fan 18 on one side of the soundproof cover 13 starts synchronously, drawing in air from the outside and the inside of the integrated unit body 1. As the airflow passes through the inside of the soundproof cover 13, it carries away the heat generated by the compressor and then discharges it from the second air outlet 21 on the back of the integrated unit body 1, reducing the risk of compressor damage due to high temperature caused by sealing. Although it will slightly weaken the sound insulation effect, since the integrated unit body 1 is the outdoor unit, it will not affect the rest and use of the personnel in the oxygen chamber. In addition, the shock absorbers at the bottom of the air conditioning compressor 4, air compressor 14, and oxygen compressor 15 can reduce the vibration of the integrated unit during operation, improve the overall stability, and reduce noise. The universal brake casters at the bottom of the integrated unit body 1 facilitate the movement and positioning of the integrated unit, reducing the difficulty of installation and maintenance.
