Description

Technical Field

[0001] The present invention relates to the technical field of air resource utilization, and in particular to an integrated air water extraction and oxygen enrichment air conditioning system and an operating method thereof. Background Art

[0002] Freshwater is an essential resource for daily human production and life. Although 72% of the Earth's surface is covered by water, freshwater resources on land only account for 2.53% of the Earth's total water volume, of which easily exploitable freshwater resources account for only 0.3%. This, coupled with the uneven spatial and temporal distribution of freshwater resources, has led to severe water crises in many regions of the world. In particular, in arid and water-scarce regions such as deserts and plateaus, freshwater has become a major constraint hindering economic development, and ensuring stable and sustainable access to freshwater remains a global challenge. Notably, the atmosphere is rich in water vapor, with its volumetric reserves exceeding the total available freshwater in swamps, wetlands, and rivers worldwide, providing an inexhaustible "natural reservoir" for water-scarce regions. Therefore, developing efficient air-to-water extraction technologies has enormous practical value.

[0003] In addition to the demand for fresh water resources, daily human production and life also rely on an adequate oxygen environment. With the development of urban modernization, people often live and work indoors for extended periods of time, especially in relatively enclosed, air-conditioned rooms in public buildings. Due to insufficient fresh air flow, indoor oxygen concentrations are low, which can easily lead to indoor hypoxia. Long-term living in an oxygen-deficient environment can cause sick building syndrome. This is especially true in plateau areas, where the oxygen partial pressure in the air decreases with increasing altitude. Long-term exposure to the low-pressure, oxygen-deficient environment of the plateau can cause varying degrees of damage to physical and mental health. Therefore, effectively supplying indoor oxygen and creating an oxygen-rich environment has become a pressing need for the development of healthy and comfortable buildings.

[0004] Based on the above background, it is of great practical significance to construct an integrated air water extraction and oxygen-enriched air conditioning system to simultaneously produce fresh water and low-concentration oxygen-enriched air to meet the needs of fresh water supply and indoor oxygen-enriched environment.

[0005] Based on this, the invention patent with patent number 201710025985.7 discloses an integrated device for high-altitude air water extraction and oxygen production and its control method. The device uses direct condensation of air water extraction and electrolysis of water to produce fresh water and oxygen-enriched air. Direct condensation water extraction uses a mechanical cooling source with a temperature below the air dew point to condense water vapor in the air. Due to the low humidity in arid areas such as deserts and plateaus, a lower cooling source temperature is required, resulting in huge energy consumption. Electrolysis of water to produce oxygen not only consumes a lot of energy, but also produces hydrogen as an impurity gas during the oxygen production process, posing a safety hazard.

[0006] In view of the above problems, there is an urgent need for a system that can produce fresh water and low-concentration oxygen-enriched air simultaneously around the clock to solve the problems existing in the existing technology. Summary of the Invention

DETAILED DESCRIPTION

[0044] In order to make the purpose of the invention, technical solutions and beneficial effects of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] like Figure 1 As shown, an integrated air water intake and oxygen enrichment air conditioning system includes: an air duct, an air duct forming an air channel; a heat pump module, the heat pump module includes an evaporator 1 and a condenser 5 connected to each other, and the condenser 5 is arranged at the air inlet end of the air duct; a heating module, the heating module includes an air-water heat exchanger 7, the air-water heat exchanger 7 is arranged in the air duct and is placed at a subsequent position of the condenser 5, and the heating module is used to provide heat for heating the air; an adsorption device, the adsorption device is arranged in the air duct and is placed at a subsequent position of the air-water heat exchanger 7; a water collection module, the water collection module includes a water collection condenser 18 and a water storage device connected and arranged below the water collection condenser 18;

[0046] During operation, it includes an adsorption stage and a desorption stage that can be switched alternately; in the adsorption stage, the evaporator 1 provides a cold source for the adsorption device, cools the adsorption device, and enhances the adsorption effect of the adsorption device on water vapor and oxygen; in the desorption stage, the condenser 5 provides heat for preheating the desorbed air, and cooperates with the heating module to further provide desorption heat for the adsorption device, so that the adsorption device can desorb, and high-humidity oxygen-rich air is generated during desorption and enters the water collection module; the evaporator 1 provides a cold source for the water collection module, condenses water vapor in the water collection module, and realizes the production of fresh water and oxygen-rich air.

[0049] Compared with the existing integrated air water intake and oxygen production technology (direct condensation water intake and electrolysis water oxygen production), the present invention provides an adsorption air water intake and temperature swing adsorption oxygen enrichment air conditioning integrated system driven by a coupled heat pump and a solar thermal collection module. Compared with direct condensation water intake, adsorption water intake has a wider range of applicable conditions and lower energy consumption, while temperature swing adsorption oxygen enrichment has lower energy consumption and convenient operation and maintenance compared with electrolysis water oxygen production. In addition, the present invention couples a heat pump and a solar thermal collection module to jointly drive the adsorption air water intake and temperature swing adsorption oxygen enrichment process, which has the advantages of energy saving and high efficiency. The front-to-back coupling arrangement of the adsorption air water intake and temperature swing adsorption oxygen enrichment process is conducive to eliminating the influence of water vapor in the air on the competitive adsorption of oxygen during the adsorption process, thereby improving the oxygen enrichment efficiency. Moreover, in the present invention, the adsorption stage and the desorption stage are switched alternately, and this cycle is repeated to achieve the simultaneous production of fresh water and low-concentration oxygen-enriched air around the clock.

[0053] Specifically, the heating module can be a conventional heating module such as a heat pump unit or a solar module. In the present invention, the solar module is used as an example for explanation. Moreover, conventional solar modules generally include a solar heat collecting plate 6, which collects heat and provides heat through the solar module.

[0054] In the present invention, the heating module includes a solar collector panel 6, a second water pump 9, an electric heater 10, and an air-to-water heat exchanger 7, forming a circuit. The solar collector panel 6 collects heat to provide heat to the air-to-water heat exchanger 7. Furthermore, the heating module also includes an electric heater 10, which provides supplemental heat, resolving the issue of insufficient heat supply from the solar collector panel 6 in low-insolation conditions. Preferably, the air-to-water heat exchanger 7 is a fin-and-tube air-to-water heat exchanger, a parallel-flow heat exchanger, or a shell-and-tube heat exchanger.

[0055] When solar energy is sufficient during the day, heat is generated by the solar thermal collecting panels 6, which are used to provide heat to further heat the air preheated by the heat pump module condenser 5; and when solar energy is insufficient at night or during the day, the circulating water in the thermal collecting module is heated by the electric heater 10, and heat is provided by the circulating water, that is, the circulating water in the solar heating module is heated by the electric heater 10 to provide heat for further heating of the air, thereby ensuring a stable and continuous supply of heat required in the air water intake-oxygen enrichment air conditioning integrated system.

[0060] The tube-fin air-water heat exchanger 7, parallel flow heat exchanger or shell-and-tube heat exchanger are all prior art and have been widely used in the petroleum, chemical, natural gas processing and other industries. That is, the internal structure of the heat exchanger in the present invention is prior art and will not be described in detail here.

[0061] In some embodiments of the present invention, a plurality of cooling water pipes 23 are provided in the water collecting condenser 18, and the plurality of cooling water pipes 23 are arranged through the water inlet and water outlet of the water collecting condenser 18; an air channel is also provided in the water collecting condenser 18, and the air channel and the cooling water pipe 23 are staggered; a plurality of baffles 22 are also provided in the water collecting condenser 18, and the plurality of baffles 22 are fixedly connected to the inner wall surface of the water collecting condenser 18, and a plurality of positioning holes 24 are opened in each baffle 22, and the plurality of cooling water pipes 23 are arranged in the positioning holes 24, and the air channel is arranged around the outer side of the baffle 22.

[0062] Furthermore, the cross-sectional shape of each baffle 22 is a combination of a gradually expanding and converging shape, with the cross-sectional width of the baffle 22 gradually increasing and then decreasing from top to bottom, and the bottom of the baffle 22 forming a certain angle with the horizontal plane. Preferably, the water collection condenser 18 is a shell and tube air-water heat exchanger 7.

[0063] Specifically, the water collection module includes a water collection condenser 18 and a water storage device disposed below the water collection condenser 18. The water storage device can be a container device capable of storing liquid, such as a water tank 19 or a water storage barrel. Preferably, the water collection condenser 18 is a shell and tube air-water heat exchanger 7.

[0064] The outside of the water collecting condenser 18 is covered with a heat-insulating layer to reduce heat transfer between the outside and the water collecting condenser 18 , thereby ensuring the temperature inside the water collecting condenser 18 .

[0065] As an embodiment of the baffle 22 of the water collecting condenser 18 in the condensation and water collecting module, a plurality of cooling water pipes 23 are provided in the water collecting condenser 18, and the plurality of cooling water pipes 23 are correspondingly connected to the cooling water flow channel 20 on the tube side of the water collecting condenser. The plurality of cooling water pipes 23 are arranged through the water inlet and outlet ends of the water collecting condenser 18; an air channel is also provided in the water collecting condenser 18, and the air channel is correspondingly connected to the air flow channel 21 on the shell side of the water collecting condenser, and the air channel is staggered with the plurality of cooling water pipes 23.

Preferably, the water collecting condenser 18 is a shell and tube air-water heat exchanger 7.

[0066] A plurality of baffles 22 are also provided in the water collecting condenser 18, and the plurality of baffles 22 are fixedly connected to the inner wall surface of the water collecting condenser 18. A plurality of positioning holes 24 are opened in each baffle 22, and a plurality of cooling water pipes 23 are passed through the positioning holes 24, and an air channel is arranged around the outer side of the baffle 22. As another embodiment of the baffle 22 of the water collecting condenser 18 in the condensing and water collecting module, a liquid leakage opening 25 is provided at the lower part of each baffle 22.

[0067] Furthermore, the surfaces of the baffles 22 and the outer surfaces of the pipes are coated with a hydrophobic coating. This helps enhance the condensation of water vapor in highly humid air, while the hydrophobic coating facilitates the collection of condensed water. A leakage opening 25 is provided at the bottom of the baffles 22 located below the water collection condenser 18, allowing all condensed water to be collected at the bottom of the water collection condenser 18.

[0068] Each baffle 22 has a cross-sectional shape that is a combination of expanding and converging. The cross-sectional width of each baffle 22 gradually increases and then decreases from top to bottom, and the bottom of each baffle 22 forms a predetermined angle with the horizontal plane. The cross-sectional shape of the water collection condenser 18 is a combination of expanding and converging. The angled bottom facilitates the collection of condensed water, which is collected at the bottom of the water collection condenser 18 through the leakage opening 25 and then stored in the water storage device.

[0069] In some embodiments of the present invention, the evaporator 1, the three-way valve, the adsorption device and the water collecting condenser 18 are connected by a pipe to form a cooling water circuit; wherein the three-way valve is used to switch the pipeline; in the adsorption stage, the pipeline is switched by the three-way valve, and the evaporator 1 and the adsorption device form a cooling water circuit, and the cooling water generated by the evaporator 1 flows back to the evaporator 1 after passing through the adsorption device; in the desorption stage, the pipeline is switched by the three-way valve, and the evaporator 1 and the water collecting condenser 18 form a cooling water circuit, and the cooling water generated by the evaporator 1 flows back to the evaporator 1 after passing through the water collecting condenser 18.

[0070] In some embodiments of the present invention, the condenser 5, the air-water heat exchanger 7, the adsorption device and the water collecting condenser 18 are arranged in the air duct in sequence; an air duct four-way valve 11 is provided between the air-water heat exchanger 7 and the adsorption device, and an air duct three-way valve 17 is provided between the adsorption device and the water collecting condenser 18.

[0071] In some embodiments of the present invention, a first fan 3 is provided in front of the inlet end of the air duct, and the first fan 3 blows into the air duct. Under the action of the first fan 3,

[0072] In detail, the condenser 5 of the heat pump module, the air-water heat exchanger 7 of the solar heating module, the oxygen-enriched adsorption bed 12, the water intake adsorption bed 14 and the water collection condenser 18 of the condensation and water collection module are connected in sequence by air ducts; a four-way valve is set on the air duct connecting the air-water heat exchanger 7 of the solar heating module and the oxygen-enriched adsorption bed, and a three-way valve is set on the air duct connecting the water intake adsorption bed 14 and the water collection condenser 18 of the condensation and water collection module.

[0073] A first air inlet A is provided at the front end of the condenser 5 of the heat pump module, a second air outlet B and a third air outlet E are provided at the upper and lower ends of the air duct four-way valve 11 respectively, a second air inlet D is provided at the upper end of the air duct three-way valve 17, the air duct outlet at the rear end of the water collection condenser 18 is the first air outlet C, and a second fan 16 is provided outside the second air inlet D.

[0074] The cooling water circuit of the heat pump module evaporator 1 is connected to the oxygen-enriched adsorption bed 12, the water intake adsorption bed 14 and the water collection condenser 18 of the condensation and water collection module through a water pump and a three-way valve.

[0075] Corresponding to the adsorption stage and desorption stage of the system operation process, in the adsorption stage, the cooling water generated by the heat pump module evaporator 1 first flows through the oxygen-rich adsorption bed 12, then enters the water intake adsorption bed 14, and finally flows back to the evaporator 1 to form a cooling water loop; while in the desorption stage, the cooling water generated by the heat pump module evaporator 1 flows into the water collection condenser 18 of the condensation and water collection module through the switching of the three-way valve, and then flows directly back to the evaporator 1 to form a cooling water loop.

[0076] In more detail, in the present invention, during the adsorption stage, the second fan 16 drives the outside air to enter from the second air inlet D. After the air duct three-way valve 17 is switched, the air first flows through the water intake adsorption bed 14, and the water vapor in the air is adsorbed by the water intake adsorption bed 14; then the air flows through the oxygen-enriched adsorption bed 12, and the oxygen in the air is adsorbed by the oxygen-enriched adsorption bed 12; then the air passes through the air duct four-way valve 11 and flows out from the third air outlet E.

[0077] During this phase, placing the water vapor adsorption process upstream of the oxygen adsorption process helps avoid the problem of reduced oxygen absorption capacity caused by water vapor adsorption by the oxygen-selective adsorbent. Furthermore, cooling water generated by the heat pump module's evaporator 1 is switched via the first three-way valve to sequentially cool the interiors of the water-intake adsorption bed 14 and the oxygen-enriched adsorption bed 12, enhancing the adsorption of water vapor and oxygen.

[0078] At the same time, the first fan 3 drives the outside air to flow in from the first air inlet A, dissipating the heat to the condenser 5 of the heat pump module in time. The air then flows through the air-water heat exchanger 7 of the solar heating module, and finally flows out from the second air outlet B after being switched by the four-way valve of the air duct.

[0079] It should be noted that the hot air and cold dry air exhausted from the second air outlet B and the third air outlet E respectively still have multiple potential uses. Typically, heat energy and cold energy can be recovered and used for indoor heating and cooling respectively according to climatic conditions.

[0080] During the desorption stage, the second air inlet D, the second air outlet B and the third air outlet E are closed, and the first fan 3 drives the outside air to flow in from the first air inlet A. The air is first preheated by the condenser 5 and continues to be heated in the air-water heat exchanger 7 in the heating module. The heated hot air is switched through the air duct four-way valve 11 to desorb and regenerate the water intake adsorption bed 14 and the oxygen-enriched adsorption bed 12. The high-humidity oxygen-enriched air generated passes through the air duct three-way valve 17 and enters the water collection condenser 18 of the condensation and water collection module through the switching of the air duct three-way valve 17 to cause water vapor condensation.

[0081] The cooling water generated by the heat pump module's evaporator 1 flows through the first three-way valve into the condenser condenser 18 of the condensation and water collection module, creating conditions for the condensation of high-humidity, oxygen-enriched air. The condensed water is collected by a water storage device located at the lower end of the condenser condenser module, while the generated oxygen-enriched air flows out of the first air outlet C, supplying an oxygen-enriched environment indoors.

[0082] The adsorption stage and the desorption stage are switched alternately and repeatedly, so as to realize the simultaneous production of fresh water and low-concentration oxygen-rich air around the clock.

[0083] In some embodiments of the present invention, the present invention may also include a control system and a detection system. The control system is used to control the start and stop of electrical components such as the electric heater 10. The detection system includes multiple temperature sensors, humidity sensors, and oxygen concentration detection components to achieve real-time monitoring and obtain certain temperature, humidity, oxygen concentration and other data information of the system, and cooperate with the control system to control the start and stop of the electrical components. The internal structure of the control system and the detection system is similar to the existing technology and will not be repeated here.

[0084] The present invention also provides an operating method of an integrated air water intake and oxygen enrichment air conditioning system, comprising an adsorption phase and a desorption phase that can be switched alternately;

[0085] During the adsorption stage, the evaporator 1 provides a cold source for the adsorption device, cools the adsorption device, and enhances the adsorption effect of the adsorption device on water vapor and oxygen;

[0086] During the desorption stage, the condenser 5 provides heat for preheating the desorbed air, and cooperates with the heating module to further provide desorption heat for the adsorption device, so that the adsorption device can desorb. During desorption, high-humidity oxygen-rich air is generated and enters the water collection module; the evaporator 1 provides a cold source for the water collection module, and condenses water vapor in the water collection module to achieve the production of fresh water and oxygen-rich air.

[0087] In detail, in the present invention, during the adsorption stage, the second fan 16 drives the outside air to enter from the second air inlet D. After the air duct three-way valve 17 is switched, the air first flows through the water intake adsorption bed 14, and the water vapor in the air is adsorbed by the water intake adsorption bed 14; then the air flows through the oxygen-enriched adsorption bed 12, and the oxygen in the air is adsorbed by the oxygen-enriched adsorption bed 12; then the air passes through the air duct four-way valve 11 and flows out from the third air outlet E.

[0088] During this phase, placing the water vapor adsorption process upstream of the oxygen adsorption process helps avoid the problem of reduced oxygen absorption capacity caused by water vapor adsorption by the oxygen-selective adsorbent. Furthermore, cooling water generated by the heat pump module's evaporator 1 is switched via the first three-way valve to sequentially cool the interiors of the water-intake adsorption bed 14 and the oxygen-enriched adsorption bed 12, enhancing the adsorption of water vapor and oxygen.

[0089] At the same time, the first fan 3 drives the outside air to flow in from the first air inlet A, dissipating the heat to the condenser 5 of the heat pump module in time. The air then flows through the air-water heat exchanger 7 of the solar heating module, and finally flows out from the second air outlet B after being switched by the four-way valve of the air duct.

[0090] It should be noted that the hot air and cold dry air exhausted from the second air outlet B and the third air outlet E respectively still have multiple potential uses. Typically, heat energy and cold energy can be recovered and used for indoor heating and cooling respectively according to climatic conditions.

[0091] During the desorption stage, the second air inlet D, the second air outlet B and the third air outlet E are closed, and the first fan 3 drives the outside air to flow in from the first air inlet A. The air is first preheated by the condenser 5 and continues to be heated in the air-water heat exchanger 7 in the heating module. The heated hot air is switched through the air duct four-way valve 11 to desorb and regenerate the water intake adsorption bed 14 and the oxygen-enriched adsorption bed 12. The high-humidity oxygen-enriched air generated passes through the air duct three-way valve 17 and enters the water collection condenser 18 of the condensation and water collection module through the switching of the air duct three-way valve 17 to cause water vapor condensation.

[0092] The cooling water generated by the heat pump module's evaporator 1 flows through the first three-way valve into the condenser condenser 18 of the condensation and water collection module, creating conditions for the condensation of high-humidity, oxygen-enriched air. The condensed water is collected by a water storage device located at the lower end of the condenser condenser module, while the generated oxygen-enriched air flows out of the first air outlet C, supplying an oxygen-enriched environment indoors.

[0093] The adsorption stage and the desorption stage are switched alternately and repeatedly, so as to realize the simultaneous production of fresh water and low-concentration oxygen-rich air around the clock.

[0094] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
