Description

Technical Field

[0001] The invention belongs to the technical field of oxygen chamber equipment, and in particular relates to an oxygen chamber air and temperature regulating system and method. Background Art

[0002] An oxygen chamber is a medical or rehabilitation aid that provides a higher concentration of oxygen than air to promote recovery from illness and injury. Large amounts of oxygen can promote tissue repair, reduce inflammation, kill anaerobic bacteria, and promote the formation of new blood vessels. According to the "China Rehabilitation Aids Catalogue (2023 Edition)", the role of oxygen chambers in assisting the rehabilitation of certain diseases has been fully recognized.

[0003] In order to improve comfort, the current oxygen cabins, such as the Chinese invention patent CN106726278A A new type of oxygen health cabin device, and the Chinese utility model patent CN218833085U A cylindrical micro-pressure oxygen-enriched cabin disclosed, are equipped with an air conditioning system, an oxygen production system, and an air compression system. The air conditioning system adjusts the temperature and humidity in the cabin; the oxygen production system provides oxygen; the air compression system is connected to the valve body pipe gas circuit to pressurize the cabin. The pressure in the cabin is usually twice or more than the atmospheric pressure. This high-pressure environment makes it easier for oxygen to enter the blood through the alveoli, thereby increasing the oxygen content in the body.

[0004] In actual use, the air compressor of the air compression system will generate a lot of heat when working, mainly because the distance between gas molecules is shortened and the frequency of molecular collisions increases during the air compression process, causing the gas temperature to rise. This phenomenon is called the compressed gas warming effect (adiabatic compression) in physics. Therefore, the air temperature discharged from the compressor is usually high, especially in the absence of subsequent cooling treatment, the compressed air will carry significant heat.

[0005] At the same time, many air compressors, especially screw compressors, use lubricating oil to reduce mechanical friction and heat dissipation. During the compression process, the lubricating oil may enter the compressed air flow and form tiny oil droplets (oil mist), which may enter the compressed air through the exhaust port of the compressor.

[0006] The hot air, oil mist and moisture generated by the air compressor when it is working will still affect the temperature inside the closed oxygen cabin, even if an air-conditioning system is installed, causing temperature and humidity disorders; at the same time, the oil mist endangers the health of the user and affects the user experience. Summary of the invention

[0007] In view of the above-mentioned deficiencies in the prior art, the problem to be solved by the present invention is that when the air compressor used in the traditional oxygen chamber provides high-pressure air, the air carries heat and oil mist, which affects the user's experience and health. The present invention provides an oxygen chamber air and temperature regulation system and method, which is provided with a water-cooled air conditioner, and a low-temperature thermostatic tank with liquid and gas cooling functions is used to provide refrigerant to the water-cooled air conditioner, cool the hot air generated by the air compressor, filter and remove the oil mist, make the oxygen chamber environment temperature more stable, avoid the harm of oil mist to the user, and improve the user experience.

After the water in the tank body is cooled, the air is cooled through heat exchange.

The water-cooled air conditioner is arranged in the oxygen chamber to cool the oxygen chamber. The heat exchanger of the water-cooled air conditioner is connected to the liquid outlet of the low-temperature constant temperature tank.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] An oxygen chamber air and temperature control system includes an air compressor 1, which provides air required by an oxygen chamber 5. Untreated compressed air may contain tiny particles, oil mist and other pollutants generated by mechanical wear. Impurities and oil mist may irritate the patient's respiratory tract, especially for sensitive patients, such as those suffering from respiratory diseases such as asthma and allergies. Clean and dry air helps to provide a comfortable breathing environment and avoid secondary health problems. Oil mist, moisture and impurities can also have a negative impact on the precision equipment in the oxygen chamber 5, causing equipment aging, corrosion, and even failure.

[0019] Importantly, if Figure 1 As shown, it also includes a low-temperature constant temperature tank 2, an oil-water separator 4, a water-cooled air conditioner 6, and a filter 3. A condensing coil is arranged in the tank body, and the condensing coil is connected to the compressor to cool the water in the tank body; an air circulation pipe is also arranged in the tank body, and the air inlet of the air circulation pipe is connected to the air outlet of the air compressor 1. After the water in the tank body is cooled, the air is cooled through heat exchange. The air circulation pipe of the low-temperature constant temperature tank 2 is a coil type, using copper pipes.

[0020] The oil-water separator 4 is connected to the air outlet of the air circulation pipeline to filter and remove the oil mist and moisture in the compressed air after cooling; the oil-water separator 4 sends the treated air to the oxygen cabin 5 through the pipeline. The water-cooled air conditioner 6 is arranged in the oxygen chamber 5 to cool the oxygen chamber 5 . The heat exchanger of the water-cooled air conditioner 6 is connected to the liquid outlet of the low-temperature constant-temperature tank 2 . The cold water medium of the water-cooled air conditioner 6 is provided by the low-temperature constant-temperature tank 2 .

[0021] The filter 3 is arranged on the pipeline between the air compressor 1 and the low temperature constant temperature tank 2 to filter impurities, oil mist and moisture in the air generated by the air compressor 1. The filter 3 can be an activated carbon type or a filter cotton type.

[0022] The oxygen chamber 5 is connected to an oxygen supply system 7, which includes an oxygen concentrator or an oxygen tank. The control system uniformly controls the operation of the air compressor 1, the low-temperature constant temperature tank 2, the water-cooled air conditioner 6, and the oxygen chamber 5, and the air compressor 1, the low-temperature constant temperature tank 2, the water-cooled air conditioner 6, and the oxygen chamber 5 do not need to be provided with a separate control panel.

[0023] like Figure 2 As shown, accordingly, a method for regulating air and temperature in an oxygen cabin is provided, comprising: In the first step, the air compressor 1 generates compressed air, and the filter 3 filters out dust, impurities, and oil in the compressed air; In the second step, the filtered air from the air compressor 1 enters the low-temperature thermostatic bath 2, and the air flows through the air circulation pipe in the tank body of the low-temperature thermostatic bath 2, and exchanges heat with the cold water in the tank body to reduce the temperature; In the third step, the cooled low-temperature air passes through the oil-water separator 4 to filter and remove the oil mist and moisture in the compressed air, and then is sent to the oxygen cabin 5; In the fourth step, the water medium of the water-cooled air conditioner 6 in the oxygen cabin 5 absorbs the heat in the cabin and enters the low-temperature constant temperature tank 2. In the tank body, it is cooled by the condenser to become cold water. The cold water enters the heat exchanger of the water-cooled air conditioner 6 for circulation and cooling.

[0024] Working principle of the present invention: Traditional oxygen cabins 5 use air conditioning for cooling, and the refrigerants used in ordinary household air conditioners are fluorine-containing, such as R22, R32, etc. These toxic refrigerants used in ordinary household air conditioners will be at a very high working pressure when the air conditioner is operating. For example, the low pressure of R22 refrigerant is about 0.5MPa, and the high pressure is about 1.3 to 1.5MPa. Once a leak occurs in a closed space such as an oxygen cabin, the consequences will be disastrous. Since the people in the cabin may be in a high-pressure environment, the cabin door cannot be opened at any time (decompression is required to exit the cabin), which poses a risk of suffocation. Once the human body inhales these fluorine-containing refrigerants, it may be paralyzed all over the body. After direct contact or inhalation of the respiratory tract, symptoms such as dizziness, headache, dullness, panting, confusion, and movement disorders may occur. Severe cases may even lead to arrhythmia or even cardiac arrest. The water-cooled air conditioner 6 uses pure water as a refrigerant to remove heat from the cabin. During the entire operation process, the pressure of the pure water in the cabin air conditioning main unit is only about 1 kilogram during operation, which is far lower than the working pressure of the fluorine-containing refrigerant in ordinary household air conditioners, eliminating the risk of leakage.

[0025] In addition, the high-temperature air generated by the air compressor 1 will affect the temperature in the cabin, and the moisture and oil mist in the air will affect the user's experience and physical and mental health. Figure 1 As shown, the present invention uses a specially made low-temperature thermostatic tank 2 to cool the water medium used by the water-cooled air conditioner 6 and the compressed air used by the oxygen chamber at the same time. The equipment has a high degree of integration, simplifies operation and management, avoids the need for multiple cooling devices, and saves space and cost. Through the filter 3 and the oil-water separator 4, these harmful substances can be effectively removed to ensure that the air entering the oxygen chamber 5 is clean, oil-free, and particle-free. This is crucial to the patient's respiratory health and avoids respiratory irritation or infection caused by inhaled pollutants.

[0026] The use of the filter 3 and the oil-water separator 4 can effectively reduce the entry of these harmful substances into the oxygen chamber 5, thereby extending the service life of the equipment and reducing maintenance costs.

[0027] Compressed air often contains a lot of water vapor. As the temperature drops, this water may condense in the oxygen chamber 5 to form liquid water. Through the pretreatment of the low-temperature constant temperature tank 2 and the oil-water separator 4, the water in the compressed air can be effectively removed to prevent the oxygen chamber 5 from being too humid. Excessive humidity can not only cause equipment failure, but also cause discomfort to patients and even cause health problems such as bacterial growth.

[0028] The low temperature constant temperature tank 2 can reduce the temperature of the compressed air and water medium, ensuring that the air entering the oxygen chamber 5 and the water-cooled air conditioner 6 keep the oxygen chamber 5 within a suitable temperature range. Too high a temperature will not only affect the patient's comfort, but may also affect the safety of the hyperbaric oxygen chamber 5. Controlling the air temperature can improve the stability and comfort during the treatment process.

[0029] Through multi-stage filtration and temperature control, the oxygen chamber 5 operates more stably, treatment is safer, and the goals of oxygen therapy are better achieved, promoting tissue healing, reducing inflammation and infection, etc.
