Description

Technical Field

[0001] This utility model belongs to the field of air water extraction technology, and in particular relates to a dual-purpose device for air water extraction and dehumidification. Background Technology

[0002] Globally, freshwater scarcity and energy consumption have become significant factors hindering the sustainable development of human society. Although approximately 70% of the Earth's surface is covered by water, the vast majority of this water is seawater, glaciers, and other bodies that are difficult to use directly. Freshwater resources directly accessible to humans account for less than 1% of the total water volume. Furthermore, due to the extremely uneven distribution of water resources, about two-thirds of the world's population faces varying degrees of water scarcity, with over 500 million people experiencing extreme water shortages. In addition, global energy demand continues to grow, accompanied by increasingly prominent environmental pollution and carbon emissions, urgently requiring the development of new energy-efficient, high-performance, and environmentally friendly technological pathways.

[0003] In the built environment, air conditioning systems constitute a major component of energy consumption. Statistics show that buildings account for approximately 40% of global energy consumption, with air conditioning systems accounting for about 50% of that. Traditional vapor compression (VC) cooling systems generally employ a heat-humidity coupled condensation dehumidification method. The system evaporation temperature must be 5-7°C below the air dew point, which not only limits the coefficient of performance (COP) but also sometimes requires reheating for dehumidification, further increasing energy consumption. The latent heat load of dehumidification accounts for approximately 40% of the total air conditioning load, becoming a crucial factor restricting energy conservation. Therefore, how to effectively reduce dehumidification energy consumption while meeting environmental control requirements has become a key focus of research and industry.

[0004] Meanwhile, air-based water extraction technology, as an important means of addressing freshwater shortages, has gradually attracted attention in recent years. Water vapor resources are ubiquitous in the air, especially in areas with high humidity or large diurnal temperature variations, showing great development potential. Extracting liquid water from the air through condensation, adsorption, and membrane separation can effectively alleviate local water supply pressures and has broad application prospects. However, existing air-based water extraction technologies are mostly independent systems, and their water extraction efficiency is closely related to environmental conditions. Limited by issues such as temperature and humidity fluctuations, high energy consumption, and poor operational stability, they are still difficult to widely replace traditional water supply methods.

[0005] To improve the system efficiency of dehumidification and air water extraction, various improvement schemes have been disclosed in related technical fields. For example, Chinese Patent CN116557983A discloses a high-efficiency dehumidification rotor mechanism. This mechanism optimizes the operating efficiency of the dehumidification rotor by setting up a reflux device and a detachable filter component, which can reduce regeneration energy consumption and dust accumulation to a certain extent, and improve the service life and operational stability of the device. However, this scheme mainly focuses on improving dehumidification performance and does not involve the collection and utilization of water resources in the air, so it cannot achieve the synergistic use of dehumidification and water extraction functions. Chinese Patent CN119686416A discloses an air water extraction device and method that operates under all working conditions. It adopts a saline gel adsorption-desorption unit, an electric heating unit, and a PID control system, which enables the device to stably extract water under relative humidity conditions of 15%~100%, significantly improving the air water extraction efficiency and environmental adaptability. This technology primarily targets the development of independent water supply systems in arid regions. While adaptable to various humidity environments, its function focuses on water extraction, neglecting the synergy between dehumidification and air quality control in building environments, making integration with air conditioning systems difficult. Chinese patent CN113684890A proposes a solution-air moisture-collecting water extraction system and method driven by an adsorption refrigeration system suitable for arid desert regions. This system combines an adsorption chiller, a solution moisture-collecting device, and a heat recovery system, improving water extraction efficiency and energy efficiency ratio through multi-stage moisture collection and tiered heat utilization. Although this solution demonstrates good water extraction capabilities under extreme climates, its design is primarily geared towards deserts or remote areas without electricity, making it unsuitable for building environments with high requirements for air quality, temperature and humidity control, and failing to effectively integrate dehumidification functionality. Chinese patent CN115316102A discloses an intelligent irrigation device based on adsorption-based air water extraction. Through the coupling of an adsorption module, a water purification unit, a water tank, and an irrigation module, it extracts water resources from the air for automated agricultural irrigation. This solution has practical significance in agricultural applications, but its core function is agricultural water use and it does not address the issue of coordinated utilization of air treatment and water resources in the built environment. Furthermore, the system coupling method is not suitable for air conditioning scenarios that require stable air volume and constant temperature air supply.

[0006] In summary, existing air-to-water extraction and dehumidification devices generally suffer from a lack of functional diversity, focusing solely on either dehumidification or water extraction, or, while coupled, failing to address the synergy between dehumidification and water extraction. In practical applications, simultaneously achieving dehumidification and water extraction often necessitates separate equipment configurations, leading to equipment redundancy, energy waste, and excessive system complexity. This hinders the realization of comprehensive, efficient, and low-carbon benefits in areas such as building energy conservation and industrial production.

[0007] Therefore, there is an urgent need for a device that can organically couple dehumidification and water extraction functions to make full use of moisture in the air, provide a feasible technical path for freshwater resource acquisition and building energy conservation, meet the comprehensive needs of high efficiency and low carbon emissions in modern building and industrial environments, and promote global sustainable development. Utility Model Content

[0008] This invention aims to solve the problems of single structure and function, inability to operate in coordination, high energy consumption and equipment redundancy in existing dehumidification and air water collection systems. It proposes a dual-purpose device that integrates dehumidification and air water collection functions. By setting up two alternating dehumidification heat exchangers, a switching valve unit, an evaporative cooler, a constant temperature water tank and a water collection device, it achieves efficient adsorption, regeneration and condensation collection of moisture in the air. It not only meets the air dehumidification needs, but also enables the acquisition of potable water, thereby improving indoor air quality and expanding the access to freshwater resources.

[0009] In view of this, the present invention provides a dual-purpose device for air water intake and dehumidification, comprising: The air intake assembly is used to draw in ambient air and deliver it to the dehumidification and heat exchange unit. The dehumidification heat exchange unit includes two dehumidification heat exchangers, a switching valve unit, and an evaporative cooler and a constant temperature water bath connected thereto. The two dehumidification heat exchangers are a first dehumidification heat exchanger and a second dehumidification heat exchanger. Adsorbent material is placed inside the first dehumidification heat exchanger and the second dehumidification heat exchanger. The adsorbent material adsorbs or regenerates moisture in the air at different temperature conditions. The evaporative cooler is used to provide cold water to the first dehumidification heat exchanger or the second dehumidification heat exchanger and to adsorb and dehumidify the adsorbent material inside it. The constant temperature water bath is used to provide hot water to the first dehumidification heat exchanger or the second dehumidification heat exchanger and to regenerate the adsorbent material inside it into water vapor. The switching valve unit is used to adjust the connection status between the evaporative cooler, the constant temperature water bath, and the first dehumidification heat exchanger and the second dehumidification heat exchanger. The air outlet assembly is connected to the first dehumidifying heat exchanger and the second dehumidifying heat exchanger, and can respectively introduce the dehumidified or regenerated air into the indoor space or guide it to the water intake device. The water collection device includes a condensing device and a water collection tank. The condensing device is used to condense the hot and humid air discharged from the air outlet assembly into liquid water, which is then collected by the water collection tank. The switching valve unit adjusts the working state of the first dehumidifying heat exchanger and the second dehumidifying heat exchanger, enabling the two dehumidifying heat exchangers to alternate between dehumidification mode and regeneration mode.

[0010] In some examples of this application, the switching valve unit includes a first four-way reversing valve and a second four-way reversing valve, used to switch the connection status of the first dehumidifying heat exchanger, the second dehumidifying heat exchanger, the evaporative cooler, and the constant temperature water bath.

[0011] In some examples of this application, the air intake assembly includes a first fan and a second fan, which are respectively used to introduce ambient air into the first dehumidifying heat exchanger and the second dehumidifying heat exchanger.

[0012] In some examples of this application, the dehumidifying heat exchanger includes a second heat exchange pipe and heat exchange plates. The second heat exchange pipe is connected to the evaporative cooler and the constant temperature water bath through a second four-way reversing valve. The adsorbent material is disposed on the heat exchange plates.

[0013] In some examples of this application, the evaporative cooler includes a first heat exchange pipe and a water collection tank. The first heat exchange pipe includes a hot water inlet and a cold water outlet. The cold water outlet is used to supply cold water to the dehumidifying heat exchanger after the first heat exchange pipe has undergone water cooling and heat exchange in the water collection tank. The hot water inlet is used to circulate the hot water after dehumidification and heat exchange in the dehumidifying heat exchanger.

[0014] In some examples of this application, the water collection tank is connected to a nozzle by a water pump, which pumps water from the water collection tank to the top of the first heat exchange pipe and sprays it onto the first heat exchange pipe for heat exchange via the nozzle.

[0015] In some examples of this application, an air inlet is provided on the evaporative cooler, which is located below the first heat exchange pipe and above the water collection tank. A third fan is provided inside the evaporative cooler to exhaust air during the cooling of the first heat exchange pipe.

[0016] In some examples of this application, a baffle plate is provided inside the evaporative cooler, the baffle plate is located below the third fan, and the nozzle is located below the baffle plate and arranged downwards.

[0017] In some examples of this application, the condensation device in the water intake device includes a condenser plate on which a semiconductor cooling component is disposed.

[0018] In some examples of this application, the high-temperature heat source of the constant temperature water bath is any one or more of a solar collector, industrial waste heat, or electric heating element.

[0019] Compared with existing technologies, the dual-purpose device for air intake and dehumidification described in this utility model has the following advantages: This application constructs a system architecture consisting of dual dehumidifying heat exchangers, dual four-way reversing valves, an evaporative cooler, a constant-temperature water bath, and water intake devices. This architecture achieves the organic coupling of dehumidification and water intake functions within the same device, allowing the two dehumidifying heat exchangers to alternate between adsorption and regeneration. Through the efficient capture and low-temperature regeneration of moisture in the air by the adsorption material, not only is the dehumidification efficiency improved, but the high-humidity air during the regeneration process is also used for condensation and water intake. At the same time, the evaporative cooler and the constant-temperature water bath serve as cold and heat sources, respectively, to provide energy, reducing energy consumption. The system also supports low-grade heat sources such as solar energy or industrial waste heat, thereby achieving energy-saving operation. It has the advantages of compact overall structure, simple operation, stable operation, and low energy consumption. Attached Figure Description

[0025] like Figures 1-4 As shown, this application discloses a dual-purpose device for air water intake and dehumidification, comprising: Air intake assembly 26 is used to draw in ambient air and deliver it to the dehumidification and heat exchange unit; The dehumidification heat exchange unit includes two dehumidification heat exchangers, a switching valve unit 28, and an evaporative cooler 7 and a constant temperature water tank 8 connected thereto. The two dehumidification heat exchangers are a first dehumidification heat exchanger 3 and a second dehumidification heat exchanger 4. Adsorbent material 24 is provided in the first dehumidification heat exchanger 3 and the second dehumidification heat exchanger 4. The adsorbent material 24 adsorbs or regenerates moisture in the air at different temperature conditions. The evaporative cooler 7 is used to provide cold water to the first dehumidification heat exchanger 3 or the second dehumidification heat exchanger 4 and adsorbs and dehumidifies the adsorbent material 24 inside it. The constant temperature water tank 8 is used to provide hot water to the first dehumidification heat exchanger 3 or the second dehumidification heat exchanger 4 and regenerate the adsorbent material 24 inside it into water vapor. The switching valve unit 28 is used to adjust the connection state between the evaporative cooler 7, the constant temperature water tank 8 and the first dehumidification heat exchanger 3 and the second dehumidification heat exchanger 4. The air outlet assembly 10 is connected to the first dehumidifying heat exchanger 3 and the second dehumidifying heat exchanger 4, and can respectively introduce the dehumidified or regenerated air into the indoor space 9 or guide the water intake device 27. The water collection device 27 includes a condensation device and a water collection tank 11. The condensation device is used to condense the hot and humid air discharged from the air outlet assembly 10 into liquid water, which is then collected by the water collection tank 11. The switching valve unit 28 adjusts the working state of the first dehumidifying heat exchanger 3 and the second dehumidifying heat exchanger 4, enabling the two dehumidifying heat exchangers to alternate between dehumidification mode and regeneration mode.

[0026] This application discloses a dual-purpose device capable of simultaneously achieving air dehumidification and water collection. It includes a fan unit for drawing in ambient air and supplying it to a subsequent processing module, and a dehumidification heat exchange unit for adsorbing and dehumidifying moisture in the air and performing pyrolysis regeneration. This unit contains two parallel dehumidification heat exchangers, referred to as the first dehumidification heat exchanger 3 and the second dehumidification heat exchanger 4. Each dehumidification heat exchanger is filled with an adsorbent material 24 with reversible water absorption and release properties. When low-temperature cold water flows in, the adsorbent material 24 adsorbs moisture from the air to complete dehumidification; when high-temperature hot water flows in, the adsorbent material 24 releases the adsorbed water vapor to complete regeneration, providing a dynamic supply for air drying and water collection. An evaporative cooler 7 and a constant-temperature water bath 8 are provided to supply cold and heat sources respectively, enabling the system to maintain the required temperature difference without the need for a high-power compressor, reducing overall energy consumption and improving energy efficiency. The switching valve unit 28 dynamically controls the flow of cold and hot water to different dehumidifying heat exchangers, enabling the two heat exchangers to operate alternately to ensure continuous and stable system operation. To regulate airflow, the device is equipped with an air inlet assembly 26 to deliver ambient air to the two heat exchangers, and an air outlet assembly 10 to guide the treated air to the indoor space 9 or to the water intake device 27. The condenser in the water intake device 27 converts water vapor into liquid water through refrigeration and drips it into the water collection tank 11 below to complete water resource recovery. The dual-purpose device for air intake and dehumidification described in this application uses the air intake assembly 26 as its core power source. It first draws in ambient air from the outside or inside the room and introduces it into the first dehumidifying heat exchanger 3 or the second dehumidifying heat exchanger 4. In the dehumidifying heat exchanger, which is currently at a low temperature, cold water flows through its internal heat exchange structure, maintaining the surface of the adsorption material 24 at a suitable moisture absorption temperature. When air passes through, the water vapor in the air is captured by the adsorption material 24, achieving dehumidification. The dried air is selectively delivered into the indoor space 9 by the air outlet assembly 10 to improve air quality. When the dehumidifying heat exchanger becomes saturated, the system switches off... The valve switching unit 28 adjusts the supply direction of cold and hot water, causing it to stop adsorption and switch to the regeneration process. That is, it switches to supplying hot water from the constant temperature water tank 8 to heat up the adsorbent material 24 and desorb it, releasing the previously adsorbed water vapor and carrying it away by the air to form a high-humidity airflow. Then, the humid airflow is sent to the condensation module of the water intake device 27 through the air outlet assembly 10. After cooling, it forms liquid water droplets that enter the water collection tank 11 to complete the extraction of water resources. The two dehumidification heat exchangers of the system alternate between dehumidification and regeneration states, with one always working in adsorption mode and the other in regeneration mode, ensuring that the air treatment and water recovery processes run continuously without interruption.

[0027] This application integrates air dehumidification and water extraction processes into the same system. In dehumidification mode, it outputs dry air to improve the indoor humidity environment, and in water extraction mode, it introduces humid air into the condensation module to obtain fresh water resources. This achieves the dual goals of air humidity regulation and water resource acquisition, effectively solving the problems of functional separation, equipment redundancy, and high energy consumption in existing technologies. By controlling the two dehumidification heat exchangers to work alternately through the switching valve unit 28, the dehumidification and regeneration processes do not conflict and are uninterrupted, avoiding energy waste and operational interruptions. It has the advantages of compact overall structure, simple operation, stable operation, and low energy consumption, and is suitable for various scenarios such as homes, office buildings, mobile devices, and temporary settlements.

[0028] As a preferred example of this application, the switching valve unit 28 includes a first four-way reversing valve 5 and a second four-way reversing valve 6, which are used to switch the connection status of the first dehumidifying heat exchanger 3, the second dehumidifying heat exchanger 4, and the evaporative cooler 7 and the constant temperature water bath 8, respectively. In some examples of this application, the first four-way reversing valve 5 is used to switch the water inlet passage of the evaporative cooler 7 and the constant temperature water bath 8 to the first dehumidifying heat exchanger 3 and the second dehumidifying heat exchanger 4, and the second four-way reversing valve 6 is used to switch the water return passage of the evaporative cooler 7 and the constant temperature water bath 8 to the first dehumidifying heat exchanger 3 and the second dehumidifying heat exchanger 4; or, the first four-way reversing valve 5 is used to switch the water return passage of the evaporative cooler 7 and the constant temperature water bath 8 to the first dehumidifying heat exchanger 3 and the second dehumidifying heat exchanger 4, and the second four-way reversing valve 6 is used to switch the water inlet passage of the evaporative cooler 7 and the constant temperature water bath 8 to the first dehumidifying heat exchanger 3 and the second dehumidifying heat exchanger 4. This application achieves dynamic switching between two dehumidifying heat exchangers and either the evaporative cooler 7 or the constant temperature water bath 8 by setting two four-way reversing valves. This enables dynamic interchange of adsorption and desorption functions, improving dehumidification efficiency and the frequency of adsorption material use. It avoids the time waste and energy efficiency reduction caused by the repeated switching of a single heat exchanger in traditional systems. In dehumidification mode, the cold water provided by the evaporative cooler 7 cools the air and improves the moisture adsorption capacity. In regeneration mode, the hot water provided by the constant temperature water bath 8 causes the adsorption material to quickly release moisture. This ensures the system's adaptability to different ambient air moisture levels and optimizes the energy structure and thermal humidity management. By simultaneously operating two sets of four-way valves, the connection path between the cold source and the heat source is switched, allowing the two dehumidifying heat exchangers to interchange roles and ensuring the continuous alternation of dehumidification and regeneration operations. This forms a stable and efficient circulating dehumidification and water intake process.

[0029] As a preferred example of this application, the air inlet assembly 26 includes a first fan 1 and a second fan 2, which are respectively used to introduce ambient air into the first dehumidifying heat exchanger 3 and the second dehumidifying heat exchanger 4. This application adopts a configuration in which the first fan 1 and the second fan 2 correspond to the two dehumidifying heat exchangers respectively. Compared with the traditional single fan or unified air supply structure, this design ensures that the two dehumidifying heat exchangers can obtain independent and sufficient airflow input during operation through a physically separated dual-fan system, so that air can directly enter the designated heat exchanger area, reducing the uneven airflow or pressure loss caused by flow path branching. Especially when one dehumidifying heat exchanger is in dehumidification mode and the other is in regeneration mode, the requirements for airflow and air pressure vary greatly under different operating conditions. The independent fan air supply structure can dynamically adjust the speed and airflow of each fan according to the system control strategy to achieve a more personalized airflow supply that fits the operating conditions, effectively avoiding the problem of reduced dehumidification capacity or low regeneration efficiency caused by insufficient airflow, thereby ensuring that each stage can operate under ideal conditions.

[0030] As a preferred example of this application, the dehumidifying heat exchanger includes a second heat exchange pipe 23 and a heat exchange plate 25. The second heat exchange pipe 23 is connected to the evaporator cooler 7 and the constant temperature water tank 8 through a switching valve unit 28. The adsorbent material 24 is disposed on the heat exchange plate 25. In the example of this application, by optimizing the structural design of the dehumidifying heat exchanger, it is made to have both high heat exchange efficiency and strong dehumidification capacity. Each dehumidifying heat exchanger consists of an internal second heat exchange pipe 23 and several heat exchange plates 25 that can exchange heat with it. The second heat exchange pipe 23 is connected to the first four-way reversing valve 5 and the second four-way reversing valve 6 of the switching valve unit 28, which can introduce cold water from the evaporative cooler 7 or hot water from the constant temperature water tank 8 as needed, and then conduct heat to the air circulation channel through the heat exchange plates 25. The adsorbent material 24 is coated on the surface of the heat exchange plates 25. When the air passes through the densely arranged heat exchange plates 25, its temperature will change rapidly. At the same time, water vapor will be captured by the adsorbent material 24 and retained in its microporous structure to achieve dehumidification. When hot water flows through the second heat exchange pipe 23, the heat exchange plates 25 will heat up and cause the moisture in the adsorbent material 24 to be released in the form of water vapor. The high humidity airflow formed at this time is introduced into the water collection device 27 for condensation and water collection.

[0031] This setup enhances the contact area with air through heat exchange plates 25, while adsorbent material 24 is distributed on its surface, allowing air to complete both heat exchange and dehumidification processes in a single flow. Furthermore, the combination of the second heat exchange pipe 23 and the switching valve unit 28 enables flexible and rapid switching between cold and hot water, allowing for flexible switching between dehumidification and regeneration processes. This ensures continuous operation of the device, which features a simple structure and low manufacturing and maintenance costs, providing strong support for the efficient operation of the entire dual-purpose device and helping to better realize the dual functions of air dehumidification and water intake.

[0032] As a preferred example of this application, the evaporative cooler 7 includes a first heat exchange pipe 16 and a water collection tank 17. The first heat exchange pipe 16 includes a hot water inlet 14 and a cold water outlet 15. The cold water outlet 15 is used to supply cold water to the dehumidifying heat exchanger after the first heat exchange pipe 16 undergoes water cooling heat exchange through the water collection tank 17. The hot water inlet 14 is used to circulate the hot water after dehumidification heat exchange in the dehumidifying heat exchanger. In the example of this application, the evaporative cooler 7 is designed with a structure including a first heat exchange pipe 16 and a water collection tank 17. One end of the first heat exchange pipe 16 is provided with a hot water inlet 14 to receive high-temperature hot water returning from the dehumidifying heat exchanger, and the other end is provided with a cold water outlet 15 to output cooled low-temperature cold water for subsequent dehumidification. The water collection tank 17 contains a certain amount of water and exchanges heat with the first heat exchange pipe 16 during operation, gradually cooling the hot water returning to the first heat exchange pipe 16 into cold water, which is then sent back to the dehumidifying heat exchanger through the cold water outlet 15. The first heat exchange pipe 16 in the evaporative cooler 7... Pipeline 16 is switched to connect with the first dehumidifying heat exchanger 3 and the second dehumidifying heat exchanger 4 via the first four-way reversing valve 5 and the second four-way reversing valve 6. When the first dehumidifying heat exchanger 3 is dehumidifying, the dehumidified hot water flows back from the first dehumidifying heat exchanger 3 to the evaporative cooler 7, is cooled, and then returns to the first dehumidifying heat exchanger 3. When the second dehumidifying heat exchanger 4 is dehumidifying, the hot water flows back from the second dehumidifying heat exchanger 4, is cooled by the evaporative cooler 7, and then returns to the second dehumidifying heat exchanger 4. This cycle repeats continuously, realizing the recycling of hot water and the continuous supply of cold water, ensuring the normal operation of the entire device.

[0033] Similarly, the pipelines in the constant temperature water bath 8 are also switched and connected to the first dehumidifying heat exchanger 3 and the second dehumidifying heat exchanger 4 through the first four-way reversing valve 5 and the second four-way reversing valve 6. Preferably, a circulation pump is installed in the circulation path of the evaporative cooler 7 and the circulation path of the constant temperature water bath 8. In the example of this application, the pipeline of the constant temperature water tank 8 is connected to the first dehumidifying heat exchanger 3 and the second dehumidifying heat exchanger 4 through a four-way reversing valve. When the system needs to regenerate the adsorbent material 24, the switching valve unit 28 switches to the state where the constant temperature water tank 8 is connected to the corresponding dehumidifying heat exchanger. The hot water in the constant temperature water tank 8 flows into the dehumidifying heat exchanger under the action of the circulating pump, providing the heat required for the regeneration of the adsorbent material 24, so that the adsorbent material 24 releases the adsorbed moisture. During the dehumidification stage, the switching valve unit 28 disconnects the passage between the constant temperature water tank 8 and the dehumidifying heat exchanger. At the same time, the circulating pump drives the cold water in the evaporative cooler to enter the dehumidifying heat exchanger, reducing the temperature of the adsorbent material 24 to achieve the adsorption of moisture in the air. Through the continuous action of the circulating pump, the stable flow of hot water and cold water in their respective circulation paths is ensured, so that the entire system can operate in an orderly manner according to the set operating conditions, and achieve efficient switching between the dehumidification and regeneration processes.

[0034] As a preferred example of this application, the water collection tank 17 is connected to the nozzle 19 by a water pump 18. The water pump 18 is used to pump water from the water collection tank 17 to the top of the first heat exchange pipe 16 and spray it onto the first heat exchange pipe 16 for heat exchange through the nozzle 19. In the example of this application, in order to improve heat exchange efficiency and enhance the cooling capacity of the system under multiple environmental conditions, the evaporative cooler 7 is further optimized to adopt a spray cooling structure, which specifically includes a water collection tank 17, a water pump 18, nozzles 19 and connecting pipes. The water collection tank 17 is located at the bottom of the evaporative cooler 7 and is used to store cooling water. During the operation of the device, the water pump 18 draws water from the water collection tank 17 to the top of the first heat exchange pipe 16, and sprays it through the nozzles 19 arranged at the top. During the falling process, the water fully contacts the surface of the first heat exchange pipe 16, so that the high-temperature hot water returned from the dehumidification heat exchanger inside the first heat exchange pipe 16 can quickly exchange heat with the external water droplets, reducing equipment costs and maintenance difficulty. Moreover, the water in the water collection tank 17 can be recycled, saving water resources and conforming to the concept of energy conservation and environmental protection.

[0035] As a preferred example of this application, an air inlet 22 is provided on the evaporative cooler 7. The air inlet 22 is located below the first heat exchange pipe 16 and above the water collection tank 17. A third fan 21 is provided inside the evaporative cooler 7 to exhaust air during the cooling of the first heat exchange pipe 16. In this example, to improve the hot water cooling efficiency and further enhance the heat exchange capacity of the system, the structure of the evaporative cooler 7 is further optimized by providing an air inlet 22 on its outer shell and a third fan 21 inside the evaporative cooler 7. The air inlet 22 is arranged below the first heat exchange pipe 16 and above the water collection tank 17. The third fan 21 and the air inlet 22 form an airflow guiding relationship to drive external air to enter from the air inlet 22 and flow through the spray cooling zone. The cooling zone is provided with multiple nozzles 19, which atomize the cooling water from the water collection tank 17 and spray it onto the first heat exchange pipe 16. On the surface of pipe 16, a fine water droplet and air convection channel are formed. The hot water flowing into the first heat exchange pipe 16 from the dehumidifying heat exchanger fully contacts the sprayed water droplets and flowing air on the outer wall of the first heat exchange pipe 16 to exchange heat. The sprayed water partially evaporates and absorbs heat to lower the temperature in contact with the first heat exchange pipe 16 and the air. The unevaporated part flows back to the water collection tank 17 for reuse. The air heated by water evaporation is discharged from the top or side of the evaporative cooler 7 by the third fan 21, thereby ensuring that the airflow in the heat exchange area continues, the evaporation process continues, and the temperature difference remains stable, forming a stable and efficient cooling mechanism.

[0036] This application establishes a stable and efficient air intake and hot and humid air exhaust system by setting up a reasonably arranged air inlet 22 and a dedicated third fan 21 in the evaporative cooler 7. When combined with the cooling water spray device, it can significantly improve the evaporation rate of the spray water and the heat exchange capacity per unit time, so that a low-temperature cooling environment can be quickly formed outside the first heat exchange pipe 16, thereby effectively cooling the return hot water. This achieves a stable supply of cold water under high-temperature conditions, effectively ensuring the continuous operation of the dehumidifying heat exchanger. At the same time, since water vapor absorbs heat significantly during evaporation, the cooling efficiency is high and no additional compressor is required for refrigeration, which greatly reduces the system's operating energy consumption and simplifies the structural complexity. In addition, the setting of the fan breaks through the heat exchange efficiency bottleneck caused by the limitation of natural convection, enhances the air velocity and the air exchange frequency of the heat exchange area, and effectively prevents the evaporation stagnation problem caused by local saturation, thereby improving the overall system's heat exchange reliability and stability.

[0037] As a preferred example of this application, a baffle plate 20 is provided inside the evaporative cooler 7, the baffle plate 20 is located below the third fan 21, and the nozzles 19 are located below the baffle plate 20 and arranged downwards. In this example, by providing a baffle plate 20 inside the evaporative cooler 7 and installing the baffle plate 20 below the third fan 21, placing it at the middle height within the airflow rising channel, and arranging multiple nozzles 19 below the baffle plate 20, the nozzles 19 are arranged with their openings facing downwards and are supplied with water by the lower water collection tank 17 and the water pump 18. This structure enables precise downward spraying of water onto the outer surface of the lower first heat exchange pipe 16 for heat exchange. Simultaneously, during the spraying process, external air enters the evaporative cooler 7 through the air inlet 22, comes into contact with the water mist to form humid and hot air, and then flows upwards. As the air flows past the baffle plate 20 located below the third fan 21, the incompletely evaporated fine water droplets carried in the air are effectively intercepted by the surface of the baffle plate 20 and fall back into the water collection pool 17 along the surface of the plate to continue participating in the cooling cycle. This avoids the water droplets being directly discharged with the fan, thus preventing waste. In addition, the baffle plate 20 also has the function of sorting the airflow direction and buffering changes in flow velocity, so that the rising air can diffuse and flow through a sufficient path before reaching the third fan 21, improving the heat exchange efficiency between the air and the sprayed water, enhancing the overall cooling capacity of the evaporative cooler 7, and realizing the simultaneous operation of air-water separation and efficient evaporation.

[0038] As a preferred example of this application, the condensation device in the water intake device 27 includes a condenser plate 13, on which a semiconductor cooling component 12 is disposed. In the example of this application, the condensation device includes a condenser plate 13 arranged in the water intake air duct, and a semiconductor cooling component 12 is installed on the condenser plate 13 to provide a stable cold source to reduce the temperature of the condenser plate so that water vapor in the hot and humid air condenses into liquid water on the surface of the condenser plate 13. When the hot and humid air, after being treated by the dehumidification heat exchanger in the regeneration process, is partially distributed to the water intake device 27 under the action of the air outlet assembly 10, the hot and humid air flows over the surface of the condenser plate 13. Due to the influence of the surface temperature of the condenser plate 13 being lower than the dew point of the air, the water vapor in the air rapidly loses heat and condenses to form liquid water droplets. This process relies on semiconductor cooling. The low-temperature environment maintained by the continuous operation of the cooling component 12 keeps the surface temperature of the condenser 13 within the effective condensation range. The formed liquid water drips down to the water collection tank 11 below under gravity and is collected uniformly without the need for additional flow guidance or demisting structures. After condensation, the air loses moisture and becomes dry air, which is eventually discharged through the exhaust port. This achieves the dual goals of resource utilization of hot and humid air and air drying. The structure is compact and the response is rapid. The semiconductor cooling component 12 is small in size, has low energy consumption, and a fast cooling speed, which makes it easy to integrate efficiently in a limited space and work in conjunction with the dehumidification module, further improving the water intake performance and practicality of the device.

[0039] As a preferred example of this application, the first dehumidifying heat exchanger 3 and the second dehumidifying heat exchanger 4 are provided with distribution air sections at their outlet ends, and the air outlet assembly 10 is located at the outlet of the distribution air section on the side away from the dehumidifying heat exchanger. In the example of this application, the air outlet assembly 10 is a dual-channel electric air valve. Through the electric switching of the air outlet assembly 10, the airflow processed by the two dehumidifying heat exchangers flows to the air outlet assembly 10, and is distributed to the indoor space 9 or the water intake device 27 through its internal valve. In some examples of this application, the air outlet assembly 10 can also be designed as two relatively independent three-way valves, each including one inlet and two outlets. The inlet end is connected to the distribution air section, and the two outlet ends are respectively connected to the indoor space 9 and the water intake device 27. This application sets up distribution air sections at the outlet ends of two dehumidifying heat exchangers and installs electrically switchable air outlet components 10 at their outlets. This allows the dehumidified airflow to be flexibly directed to the indoor space 9 or the water intake device 27 according to actual needs after being gathered. This enables the free switching between dehumidifying air supply and condensing water intake functions in one system, significantly improving the functional integration and adaptability of the device. At the same time, this design avoids the repeated laying of delivery pipelines and multiple fan systems, simplifies the overall structure, reduces equipment costs, and saves space.

[0040] As a preferred example of this application, the high-temperature heat source of the constant-temperature water tank 8 is any one or more of a solar collector, industrial waste heat, or electric heating element. In the example of this application, the constant-temperature water tank 8 serves as an intermediate heat source for heat storage and transfer. At its high-temperature end, heat energy is input through at least one heat source, which can be a solar collector, industrial waste heat, or electric heating element. The water in the constant-temperature water tank 8 is heated to a set temperature under the action of the heat source and transported to the dehumidification heat exchanger through a circulating pump system. Then, through water-air heat exchange, heat is transferred to the air or the surface of the adsorbent material 24, raising the temperature of the environment where the adsorbent material 24 is located inside the dehumidification heat exchanger during the regeneration stage. This causes the adsorbent material 24 to release the adsorbed moisture, achieving efficient regeneration.

[0041] The dual-purpose device for air intake and dehumidification disclosed in this application mainly consists of two parts: an air duct unit and a hot and cold water supply unit. The air duct unit includes an air inlet section, a dehumidification and water intake treatment section, and a distribution section. In the air inlet section, air is driven into the first dehumidification heat exchanger 3 and the second dehumidification heat exchanger 4 of the dehumidification and water intake treatment section by a first fan 1 and a second fan 2. The dehumidification and water intake treatment section is located in the middle of the air duct. Ambient air flows to the dehumidification and water intake sections of the dehumidification heat exchange unit under the action of the first fan 1 and the second fan 2, corresponding to the air ducts where the first dehumidification heat exchanger 3 and the second dehumidification heat exchanger 4 are located, respectively. The pre-treated air is processed by the first dehumidification heat exchanger 3 and the second dehumidification heat exchanger 4. The cold water for adsorption and the hot water for regeneration in the dehumidification heat exchangers are provided by an evaporative cooler 7 and a constant temperature water tank 8, respectively. In the distribution section, the air, after being processed by the dehumidification heat exchangers, flows to the air outlet assembly 10 and is distributed to the indoor space 9 or the water intake device 27 via valves. In the example of this application, the first fan 1 and the second fan 2 are axial flow fans, and the air outlet assembly 10 is a dual-channel electric air valve.

[0042] The hot and cold water supply unit includes a switching valve unit 28, an evaporative cooler 7, and a constant temperature water tank 8. The evaporative cooler 7 serves as a cold source for the dehumidifying heat exchanger to adsorb at low temperatures, thus meeting the cooling requirements of the air during the dehumidification stage. The constant temperature water tank 8 serves as a heat source to provide the heat required during the regeneration process, which is used for the dehumidifying heat exchanger to regenerate at high temperatures. This allows the system to simultaneously perform water intake and dehumidification operations. The switching between the two operating conditions is regulated by the switching valve unit 28, which includes a first four-way reversing valve 5 and a second four-way reversing valve 6.

[0043] In the example of this application, the dual-purpose device for air intake and dehumidification described in this application has two operating modes through the adjustment of the switching valve unit 28. The first mode is as follows: Figure 1 As shown, this is the dehumidification mode of the first dehumidifying heat exchanger 3 and the regeneration mode of the second dehumidifying heat exchanger 4. By adjusting the first four-way reversing valve 5 and the second four-way reversing valve 6, the first dehumidifying heat exchanger 3 and the second dehumidifying heat exchanger 4 are connected to the evaporative cooler 7 and the constant temperature water tank 8, respectively. The evaporative cooler 7 acts as a cold source, supplying cold water to the first dehumidifying heat exchanger 3 to process the air while simultaneously dehumidifying. The constant temperature water tank 8 acts as a heat source, supplying hot water to the second dehumidifying heat exchanger 4 for regeneration. After operating for a period of time during the dehumidification stage, the adsorption capacity of the adsorbent material 24 in the first dehumidifying heat exchanger 3 approaches saturation. At this point, the second operating mode is switched by adjusting the switching valve unit 28, as shown... Figure 2 As shown, the second dehumidifying heat exchanger 4 dehumidifies and the first dehumidifying heat exchanger 3 regenerates. Furthermore, by switching the first four-way reversing valve 5 and the second four-way reversing valve 6, the system can achieve a mode in which dehumidification and water intake can be carried out simultaneously and continuously.

[0044] In the examples of this application, the airflow direction of the dual-purpose air intake and dehumidification device is as follows: Figure 1 , Figure 2 As shown, the wind path is represented by double lines with hollow arrows, including: During dehumidification by the first dehumidifying heat exchanger 3 and regeneration by the second dehumidifying heat exchanger 4: (a) First fan 1 → First dehumidifying heat exchanger 3 → Air outlet assembly 10 → Indoor space 9; (b) Second fan 2 → Second dehumidification heat exchanger 4 → Air outlet assembly 10 → Condenser fin 13.

[0045] The first dehumidifying heat exchanger 3 is regenerated, and the second dehumidifying heat exchanger 4 is dehumidifying: (c) First fan 1 → First dehumidifying heat exchanger 3 → Air outlet assembly 10 → Condenser fin 13; (d) Second fan 2 → Second dehumidifier heat exchanger 4 → Air outlet assembly 10 → Indoor space 9.

[0046] The water path of the air intake and dehumidification dual-purpose device is as follows: Figure 1 , Figure 2 As shown, the waterway is represented by a single line with a solid arrowhead, including: (e) Evaporative cooler 7 → First four-way reversing valve 5 → First dehumidifying heat exchanger 3 → Second four-way reversing valve 6 → Evaporative cooler 7; (f) Constant temperature water bath 8 → First four-way reversing valve 5 → Second dehumidifying heat exchanger 4 → Second four-way reversing valve 6 → Constant temperature water bath 8.

[0047] The first dehumidifying heat exchanger 3 is regenerated, and the second dehumidifying heat exchanger 4 is dehumidifying: (g) Evaporative cooler 7 → First four-way reversing valve 5 → Second dehumidifying heat exchanger 4 → Second four-way reversing valve 6 → Evaporative cooler 7; (h) Constant temperature water bath 8 → First four-way reversing valve 5 → First dehumidifying heat exchanger 3 → Second four-way reversing valve 6 → Constant temperature water bath 8.

[0048] In the circulating water circuit, e and g are dehumidification and cooling sections, which remove moisture from the air and regulate the air temperature through the dehumidification heat exchanger; f and h are regeneration and water intake sections, which regenerate the adsorbent by heating and process the air at the same time, activate the semiconductor refrigeration component 12 and allow the air to flow to the condenser plate 13 to obtain water.

[0049] To understand the dehumidification and water extraction efficiency of the device, the applicant conducted a continuous dehumidification-regeneration cycle experiment. A thermally responsive salt-loaded composite material, P-SG-L, composed of PNIPAM (POLY(N-ISOPROPYL ACRYLAMIDE), poly(N-isopropylacrylamide)), silica gel, and lithium chloride, was used as the adsorbent material 24 coated on the dehumidification heat exchanger. Under conditions of 20℃ and 70%RH, the equilibrium adsorption capacity of P-SG-L was 1.59 g / g; under conditions of 30℃ and 70%RH, the equilibrium adsorption capacity of P-SG-L reached 2.01 g / g, far exceeding that of traditional silica gel adsorbents (<0.4 g / g), and also greater than that of silica-salt (Silica / LiCl adsorption capacity 0.5 g / g) composite adsorbents. This material possesses high adsorption capacity and good desorption capacity. PNIPAM's critical dissolution temperature (LCST) is 32℃. PNIPAM contains two special functional groups: a hydrophilic amide group (-CONH-) and a hydrophobic isopropyl-CH(CH3)2. When the ambient temperature is below its LCST, the hydrophilic group binds to water molecules through hydrogen bonds, exhibiting a stretched coil structure; otherwise, the chain contracts, becoming a tight colloidal structure, squeezing out water molecules and thus reducing desorption energy consumption. P-SG-L can effectively utilize low regeneration heat sources in the range of 40℃-60℃, while the regeneration temperature of silica gel-salt composite adsorbents is typically 60-90℃, resulting in higher energy consumption.

[0050] When the operating conditions are set, by adjusting the parameters of the first fan 1 and the second fan 2, the ambient air enters the dehumidification and heat exchange unit, the wind speed is maintained at 0.5m / s, the hot water temperature in the constant temperature water tank 8 is 50℃, the cold water temperature in the evaporative cooler 7 is 20℃, and the switching time between dehumidification and regeneration water intake is 600s.

[0051] The final result is: the dual-purpose device for air intake and dehumidification in this application is 30 o The average water removal capacity was 4.43 g / kg and the COP was 0.49 under C&60%RH conditions. Furthermore, when SG-L (silica gel-salt composite adsorbent) adsorbent material was coated onto a dehumidifying heat exchanger for testing, under the same experimental conditions, the average water removal capacity of the dual-purpose device using SG-L was 2.33 g / kg and the COP was 0.37.

[0052] Both dual-purpose devices coated with adsorbent P-SG-L and dual-purpose devices coated with adsorbent SG-L can achieve the dual purpose of water intake, drinking, and dehumidification. The dual-purpose device coated with adsorbent P-SG-L has a higher dehumidification capacity and a larger COP than the dual-purpose device coated with adsorbent SG-L.

[0053] The adsorbent 24 used in this application is a P-SG-L type composite adsorbent. This material is formed by the combination of thermally responsive polymer PNIPAM and inorganic salt. It has significant water vapor adsorption capacity and low-temperature regeneration characteristics. Compared with the technical contradictions of traditional adsorbents, which have high adsorption capacity but high regeneration temperature or low regeneration temperature but limited adsorption capacity, this material combines the advantages of both. It can still maintain efficient adsorption and desorption performance under low energy consumption conditions. Applying it to the dehumidification and air water extraction dual-purpose device of this application can effectively improve the overall water vapor treatment capacity and operating efficiency of the device. During the dehumidification stage, the P-SG-L adsorbent can quickly absorb a large amount of moisture from the air, making the air entering the room drier and more comfortable, significantly improving the living and working environment. At the same time, its high moisture absorption capacity also means that it can absorb more moisture from the air per unit time. In the subsequent regeneration stage, the stored moisture is released by heating the adsorbent material, obtaining more recyclable liquid water to meet the needs of domestic or industrial water use. In terms of heat source selection, the low-temperature desorption characteristics of this material allow it to be regenerated by low-grade heat sources such as solar collectors or industrial waste heat, no longer relying on traditional high-energy-consuming methods such as electric heating or gas heating. This effectively reduces the operating cost of the device, improves energy utilization efficiency, and gives the device significant advantages of being green and environmentally friendly, low in energy consumption, and having a wide operating range.
