Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an oxygen-enhancing air conditioner. Background Art

[0002] Oxygen is an essential element for human metabolism. Oxygen from the air enters the bloodstream through breathing, binds to the hemoglobin in red blood cells, and is then circulated throughout the body. People living in oxygen-deficient environments experience decreased sleep quality, with frequent awakenings, nightmares, and drowsiness in the early morning. Periodic apnea during sleep is also common, and this may be a significant factor in premature awakenings. Working in an oxygen-deficient environment (compared to an environment with sufficient oxygen) shortens attention span, increases mental fatigue, and reduces visual acuity. This condition, especially when performing precision work, can lead to poor decisions due to brain hypoxia. Living and working in such an environment significantly impacts human function. Hypoxia reduces blood oxygen levels, increasing the workload on the cardiovascular system. Chronic hypoxia can lead to organ disease. Hypoxia can also cause constriction of pulmonary blood vessels, leading to high pressure in the pulmonary arteries, and may trigger acute and chronic cardiovascular diseases, such as emphysema, cor pulmonale, heart failure, and other diseases; at the same time, hypoxia can damage brain tissue cells, causing disorders in the energy metabolism of the entire tissue cells, and then cell degeneration and necrosis, affecting the normal functioning of the human body, and the body is in a sub-healthy state for a long time, posing a serious threat to life safety.

[0003] Currently, the main existing technical solution for regulating oxygen concentration in the air conditioning industry is fresh air technology. This technology actively draws outdoor air into the room, creating a pressure difference that forces low-oxygen air outside, thereby indirectly increasing indoor oxygen concentration.

[0004] However, the current fresh air solution also has obvious shortcomings. For example, fresh air technology does not specifically increase oxygen. By introducing outdoor air into the room, not only will the oxygen concentration change, but other air components and parameters will also change, such as changing the indoor temperature and humidity, and introducing outdoor particulate pollutants. To avoid these problems, the fresh air system needs to add modules such as filters to filter out particles and other pollutants. Moreover, in order to effectively increase the oxygen concentration, the fresh air module needs to achieve a larger air volume, resulting in a larger module size; high fan air volume will also bring high noise problems. In addition, the fresh air solution requires effective air exchange between indoors and outdoors, so a thicker fresh air duct is required, and a larger hole needs to be opened in the wall. The construction is cumbersome and costly.

[0005] In addition, oxygen enrichment equipment in other industries, such as diffused oxygen concentrators, uses molecular sieves to separate nitrogen and oxygen from outdoor air to produce high-purity oxygen, which is then transported indoors for oxygen enrichment. However, molecular sieves, a key material for nitrogen and oxygen separation, are sensitive to dirt and water, while outdoor air quality is poor, containing not only dust and particulate matter but also humid water vapor. This not only causes the molecular sieve's micropores to be clogged by airborne particulate matter, significantly reducing oxygen production capacity, but the intrusion of humid water vapor also shortens the molecular sieve's service life. Therefore, common space oxygen concentrators on the market require the addition of multi-layer filtration modules and dehumidification modules to extend the machine's service life. Utility Model Content

[0006] The utility model aims to solve the above technical problem, that is, to solve the problem that the existing oxygen-enriched air conditioner uses outdoor air for oxygenation, which is disadvantageous to the oxygenation module.

[0028] like Figure 1As shown, an embodiment of the present application provides an oxygen-enriched air conditioner, comprising an indoor unit 1, an outdoor unit 2, and an oxygen-enriching module 3. The indoor unit 1 is arranged indoors, and the outdoor unit 2 is arranged outdoors. The oxygen-enriching module 3 is arranged on the side of the outdoor unit 2, and is arranged outdoors together with the outdoor unit 2. It is used to separate nitrogen and oxygen from the indoor air transported to the oxygen-enriching module 3 through the indoor unit 1 to generate high-concentration oxygen; and then the high-concentration oxygen is dispersed indoors through the indoor unit 1 to increase the indoor oxygen concentration. The oxygen-enriching module 3 is connected to the indoor unit 1 through a first pipeline 4 and a second pipeline 5; the first pipeline 4 is used to transport the indoor air to the oxygen-enriching module 3 through the indoor unit 1; the second pipeline 5 is used to transport the high-concentration oxygen generated by the oxygen-enriching module 3 to the indoor unit 1.

[0029] Furthermore, if Figure 2 As shown, the oxygen enrichment module 3 includes an air compression unit 31 and a nitrogen-oxygen separation unit 32. The air compression unit 31 is connected to the indoor unit 1 via a first pipeline 4 and is connected to the nitrogen-oxygen separation unit 32 via a third pipeline (not shown in the figure); the nitrogen-oxygen separation unit 32 is connected to the indoor unit 1 via a second pipeline 5.

[0030] Furthermore, if Figure 2 As shown, the air compression unit 31 includes an air compressor 311; the air inlet of the air compressor 311 is connected to the indoor unit 1 via a first pipeline 4; and the exhaust of the air compressor 311 is connected to the nitrogen-oxygen separation unit 32 via a third pipeline. By connecting the air compressor 311 to the indoor unit 1 via the first pipeline 4, the indoor unit 1 can deliver indoor air to the air inlet of the air compressor 311 via the first pipeline 4, where it is drawn into the air compressor 311. The high-pressure air compressed by the air compressor 311 is then delivered to the nitrogen-oxygen separation unit 32 via a third pipeline connected to the exhaust of the air compressor 311. Preferably, the air compressor 311 is an oil-free air compressor.

[0031] In order to dissipate heat for the air compressor 311 , a heat dissipation device 312 is further provided in the air compression unit 31 .

[0032] Furthermore, the nitrogen and oxygen separation unit 32 includes a solenoid valve 321, a first molecular sieve module 322, and a second molecular sieve module 323. The solenoid valve 321 includes an air inlet, an exhaust hole, a first air outlet, and a second air outlet. The air inlet is connected to the exhaust port of the air compressor 311 through a third pipeline to introduce the high-pressure indoor air compressed by the air compressor 311 into the solenoid valve 321; the first air outlet is connected to the inlet end of the first molecular sieve module 322, and the second air outlet is connected to the inlet end of the second molecular sieve module 323, so that the high-pressure indoor air introduced into the solenoid valve 321 can be controlled by the solenoid valve 321 to be delivered to the first molecular sieve module 322 or the second molecular sieve module 323.

[0033] Both the first molecular sieve module 322 and the second molecular sieve module 323 are equipped with molecular sieves, which have the ability to adsorb nitrogen. Molecular sieves can be used to separate nitrogen and oxygen through adsorption and pressure swing adsorption, thereby producing high-concentration oxygen. The molecular sieve adsorption method utilizes the properties of molecular sieves to separate nitrogen and oxygen by passing compressed air through a special adsorbent called a molecular sieve. This method exploits the differences in the molecular sieve's adsorption capacity for molecules of different sizes, selectively adsorbing nitrogen and other impurities in the air while allowing oxygen to pass through. Pressure swing adsorption, on the other hand, utilizes the molecular sieve's adsorption and pressure swing properties to produce nitrogen. Under high pressure, nitrogen passes through the molecular sieve's pores and is adsorbed on the molecular sieve's surface. Reducing the pressure then releases the adsorbed nitrogen. This process not only converts air into high-purity nitrogen but also is highly efficient, enabling rapid nitrogen adsorption. Furthermore, by reducing the pressure, the nitrogen adsorbed on the molecular sieve's surface is recovered, reducing production time and costs.

[0034] By utilizing the above-mentioned characteristics of the molecular sieve, when the high-pressure indoor air passes through the molecular sieve in the first molecular sieve module 322 or the second molecular sieve module 323 , nitrogen in the air can be absorbed by the molecular sieve to obtain high-concentration oxygen.

[0035] The nitrogen and oxygen separation unit 32 is also provided with an air storage tank 324. The air storage tank 324 is connected to the outlet of the first molecular sieve module 322 and the outlet of the second molecular sieve module 323. This allows the high-concentration oxygen generated by the nitrogen and oxygen separation of the compressed indoor air in the first molecular sieve module 322 or the second molecular sieve module 323 to enter the air storage tank 324 through the outlet of the first molecular sieve module 322 or the outlet of the second molecular sieve module 323 and be stored there. The air storage tank 324 is also connected to the indoor unit 1 via a second pipeline 5. This allows the high-concentration oxygen in the air storage tank 324 to be transported to the indoor unit 1 through the second pipeline 5 and enter the room through the indoor unit 1, thereby increasing the oxygen concentration in the indoor space.

[0036] In order to detect the oxygen concentration of the air in the room where the indoor unit 1 is located, an oxygen concentration sensor may be provided in the indoor unit 1 to detect the oxygen concentration of the indoor air.

[0037] Furthermore, a filter module (not shown in the figure) can be provided in the indoor unit 1 to filter the air delivered to the air compressor 311 through the first pipeline 4, thereby filtering out impurities such as particles in the air and reducing the influence of impurities in the air on the nitrogen adsorption capacity of the molecular sieves in the first molecular sieve module 322 and the second molecular sieve module 323 in the oxygenation module 3.

[0038] Furthermore, the oxygen-enhancing air conditioner in this embodiment also includes a control device (not shown). The control device is connected to the air compressor 311, the solenoid valve 321, and the oxygen concentration sensor. The control device controls the operation of the air compressor 311 and the solenoid valve 321 by connecting to the air compressor 311 and the solenoid valve 321. The control device is connected to the oxygen concentration sensor to read the real-time oxygen concentration of the indoor air collected by the oxygen concentration sensor. Based on the real-time oxygen concentration of the indoor air, the control device determines whether to activate the oxygen enrichment module 3 to deliver high-concentration oxygen to the room to increase the oxygen concentration of the indoor air.

[0039] In a specific embodiment, Figure 1 As shown, the oxygenation module 3 is arranged at the upper part of the outdoor unit 2. The oxygenation module 3 can be arranged at other positions of the outdoor unit 2 as needed. The embodiment of the present application does not specifically limit the position of the oxygenation module 3 relative to the outdoor unit 2. In addition, in the oxygenation module 3, the nitrogen and oxygen separation unit 32 is on the left, and the air compression unit 31 is on the right. The relative positions of the nitrogen and oxygen separation unit 32 and the air compression unit 31 in the oxygenation module 3 can be set as needed. For example, the nitrogen and oxygen separation unit 32 and the air compression unit 31 can be arranged up and down in the oxygenation module 3. The embodiment of the present application does not specifically limit the arrangement of the nitrogen and oxygen separation unit 32 and the air compression unit 31 in the oxygenation module 3.

[0040] In the embodiment of the present application, when the oxygen-enhancing air conditioner is working, the oxygen concentration sensor arranged in the indoor unit 1 collects the oxygen concentration value in the room where the indoor unit 1 is located at a set frequency, for example, once every five seconds; and sends the collected oxygen concentration value to the control device.

[0041] Upon receiving the real-time indoor oxygen concentration value, the control device compares it with a pre-set oxygen concentration threshold to determine whether the indoor oxygen concentration is too low. If the real-time oxygen concentration value is greater than the pre-set oxygen concentration threshold, the control device determines that the current indoor oxygen concentration is normal and there is no need to activate the oxygen enrichment module 3. If the real-time oxygen concentration value is lower than the pre-set oxygen concentration threshold, the control device determines that the current indoor oxygen concentration is too low and requires activation of the oxygen enrichment module 3.

[0042] At this point, the control device sends instructions to the air compressor 311 in the air compression unit 31 and the solenoid valve 321 in the nitrogen-oxygen separation unit 32, activating them. The air compressor 311 draws indoor air through the first pipeline 4 and the indoor unit 1 to the air compressor 311 in the oxygenation module 3 located outdoors. Before entering the air compressor 311, the indoor air is first filtered by a filter module located in the indoor unit 1 to remove impurities such as particulate matter. Because indoor air is much cleaner than outdoor air, the operating pressure of the filter module is lower than that of drawing outdoor air into the oxygenation module 3 for nitrogen-oxygen separation. Furthermore, this significantly extends the service life of the molecular sieves in the first molecular sieve module 322 and the second molecular sieve module 323 in the oxygenation module 3. Furthermore, unlike the outdoors, indoor air is not subject to rain or snow, so moisture damage to the molecular sieves is significantly reduced.

[0043] The air entering the air compressor 311 is compressed and then transported from the exhaust port of the air compressor 311 to the solenoid valve 321 through the air inlet of the solenoid valve 321 via the third pipeline.

[0044] Then, the control device controls the solenoid valve 321 so that the compressed indoor air alternately enters the first molecular sieve module 322 and the second molecular sieve module 323 to separate nitrogen and oxygen, produce high-concentration oxygen (concentration 30%-96%), and deliver it to the indoor unit 1.

[0045] Specifically, when solenoid valve 321 is energized, its first outlet opens and its second outlet closes, allowing compressed indoor air to enter the first molecular sieve module 322. Nitrogen in the pressurized air is adsorbed by the molecular sieves in the first molecular sieve module 322, generating highly concentrated oxygen. This highly concentrated oxygen enters the gas storage tank 324 through the outlet of the first molecular sieve module 322, is transported to the indoor unit 1 via the second pipeline 5, and is then evenly distributed throughout the room by the indoor unit 1's air supply system.

[0046] When the molecular sieve in the first molecular sieve module 322 reaches saturation in its nitrogen adsorption capacity, the control device de-energizes the solenoid valve 321, closing its first outlet and opening its second outlet. Compressed indoor air is no longer supplied to the first molecular sieve module 322, but is instead supplied to the second molecular sieve module 323. Nitrogen in the pressurized air is adsorbed by the molecular sieve in the second molecular sieve module 323, generating a high-concentration oxygen gas. This high-concentration oxygen gas enters the gas storage tank 324 through the outlet of the second molecular sieve module 323 and is then transported to the indoor unit 1 via the second pipeline 5. The air supply system of the indoor unit 1 then evenly distributes the oxygen gas to every corner of the room.

[0047] At the same time, since no compressed air enters the first molecular sieve module 322, the pressure in the first molecular sieve module 322 decreases, causing the molecular sieve in the first molecular sieve module 322 to release the restriction on the nitrogen it adsorbed, allowing the adsorbed nitrogen to be released from the molecular sieve and accumulate in the first molecular sieve module 322. When the pressure reaches a certain level, the solenoid valve 321 opens its exhaust port and discharges the desorbed nitrogen into the outdoor ambient air.

[0048] Then, when the ability of the molecular sieve in the second molecular sieve module 323 to adsorb nitrogen reaches saturation, the control device energizes the solenoid valve 321, opens the first air outlet of the solenoid valve 321, and closes the second air outlet, so that the compressed indoor air is switched from being input into the second molecular sieve module 323 to being input into the first molecular sieve module 322, and the above-mentioned nitrogen and oxygen separation operation is repeated.

[0049] At the same time, the molecular sieve in the second molecular sieve module 323 also performs a desorption operation to release the nitrogen adsorption due to the pressure reduction as described above and discharge the nitrogen to the outside.

[0050] The solenoid valve 321 repeats the above operation under the control of the control device, so that the indoor air is continuously compressed by the air compressor 311 and then delivered to the solenoid valve 321. Under the control of the solenoid valve 321, the indoor air is alternately delivered to the first molecular sieve module 322 and the second molecular sieve module 323 for continuous nitrogen and oxygen separation, thereby realizing direct oxygen production from the air and continuously delivering high-concentration oxygen into the room to achieve the effect of increasing oxygen.

[0051] When the real-time oxygen concentration measured by the oxygen concentration sensor in indoor unit 1 exceeds a preset oxygen concentration threshold, the control device determines that the indoor oxygen concentration has reached the set requirement and sends a command to oxygenation module 3, causing air compressor 311 and solenoid valve 321 to stop operating. The control device restarts oxygenation module 3 and repeats the above oxygenation operation until the real-time oxygen concentration in the room falls below the set oxygen concentration threshold.

[0052] Figure 3 The figure shows the flow diagram of indoor air, nitrogen, and oxygen during the oxygen enrichment operation of the oxygen enrichment air conditioner in the embodiment of the present application. The red line represents the flow path of indoor air, the brown line represents the flow path of nitrogen, and the green line represents the flow path of oxygen.

[0053] The above-mentioned sample increase method adopts a molecular sieve pressure swing adsorption scheme, using indoor air as raw material and molecular sieve as adsorbent, extracting indoor air into the oxygen production module for nitrogen and oxygen separation, and then delivering high-concentration oxygen into the room. This method does not require complex chemical reactions or high-temperature and high-pressure operations, so it has high energy utilization efficiency, low system energy consumption, and relatively economical operating costs. In addition, the operation of the oxygenation module 3 is controlled by a control device according to the real-time oxygen concentration in the room, and the operating state of the oxygenation module 3 can be adjusted in real time according to the indoor oxygen concentration demand, reducing the need for manual intervention. It is also suitable for installation and use in various industrial environments. This method is simple to operate, easy to implement, and has the characteristics of automated control, and can achieve efficient, high-purity, and automated preparation of oxygen.

[0054] The oxygen-enhancing air conditioner in the embodiments of the present application extracts indoor air into an outdoor oxygenation module for nitrogen and oxygen separation, generating high-concentration oxygen that is then delivered indoors to increase the indoor oxygen concentration. Using indoor air rather than outdoor air for nitrogen and oxygen separation avoids the adverse effects of outdoor air contamination and humidity on the oxygen production capacity of the oxygenation module. Figure 4 This is a comparison chart of the nitrogen and oxygen separation effects of indoor and outdoor air when using expansion modules of the same capacity for nitrogen and oxygen separation. As can be seen from the chart, the effect of using indoor air to produce oxygen is significantly better than that of using outdoor air to produce oxygen in the same period of time.

[0055] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
