Description

Technical Field

[0001] This invention relates to the field of air-water extraction technology, and in particular to a highly efficient and energy-saving adaptive all-weather composite air-water extraction device. Background Technology

[0002] Air-based water extraction technologies mainly include mist capture, direct condensation, and adsorption. Mist capture technology is only suitable for environments with extremely high relative humidity, and is greatly limited by location and time. Direct condensation technology obtains condensate by directly cooling air to below the dew point temperature. Its working principle is simple and the technology is mature, making it more suitable for water extraction under high relative humidity conditions. However, it is difficult to operate under low relative humidity conditions and consumes a lot of energy, even facing problems such as machine frosting and failure to extract water. Adsorption technology, using adsorbents, can achieve water extraction under a wide range of relative humidity conditions. However, existing research shows that its water extraction efficiency is low under high relative humidity conditions, and its energy consumption is significantly higher than that of direct condensation technology. Therefore, it is more suitable for operation under low relative humidity conditions.

[0003] A search of existing technologies revealed that current air-to-water extraction devices generally employ single direct condensation or adsorption air-to-water extraction technologies. Chinese patent application CN202321057677.X designs a structure for a direct condensation air-to-water extraction device, improving its stability and condensation efficiency. However, this device suffers from high energy consumption and low water extraction efficiency in low-temperature and low-humidity environments, and also has disadvantages such as failure to extract water due to excessively low dew point temperatures and machine frosting, limiting its application scope. Another existing Chinese patent application CN201710711661.9 designs a method for using an air-to-water extraction device combining a multi-stage rotor and a refrigeration unit, utilizing single adsorption air-to-water extraction technology. While exhibiting wide humidity applicability, it suffers from low water extraction efficiency and energy utilization in high-relative-humidity operating environments.

[0004] However, in real life, relative humidity fluctuates greatly throughout the year and between day and night. Devices that rely solely on air-based water extraction technology cannot meet the demand for energy-efficient water production under all weather conditions in practical applications. Summary of the Invention

[0005] The purpose of this invention is to provide a highly efficient and energy-saving adaptive all-weather composite air-water intake device, solving the problem of how to achieve efficient and energy-saving water production without being limited by geographical location or time.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

A third three-way valve is installed on the pipeline of the second inlet air duct, and a fourth three-way valve is installed on the pipeline of the second outlet air duct.

[0014] In this embodiment, specifically, a first air filter is installed between the first outlet air duct and the first three-way valve; and a second air filter is installed between the second outlet air duct and the third three-way valve.

[0015] In this embodiment, specifically, one end of the second three-way valve connected to the first outlet air duct is connected to the first water collector, and the other end is connected to the heat exchanger; one end of the first three-way valve connected to the first inlet air duct is connected to the ambient air, and the other end is connected to the fifth three-way valve through a pipeline; the other end of the fifth three-way valve is connected to the external environment.

[0016] The fourth three-way valve connected to the second outlet air duct has a second water collector connected to one end and a heat exchanger connected to the other end; the third three-way valve connected to the second inlet air duct has one end connected to the ambient air and the other end connected to the sixth three-way valve through a pipeline; the other end of the sixth three-way valve is connected to the external environment.

[0017] In this embodiment, specifically, the first three-way valve, the second three-way valve, the third three-way valve, the fourth three-way valve, the fifth three-way valve, and the sixth three-way valve are all solenoid valves; the four-way directional valve is a solenoid directional valve; the first three-way valve, the second three-way valve, the third three-way valve, the fourth three-way valve, the fifth three-way valve, the sixth three-way valve, the four-way directional valve, the first fan, the second fan, and the compressor are all intelligently controlled by a PLC module with integrated energy efficiency algorithms, which adaptively switches between "direct condensation air water intake" and "adsorption air water intake" operation modes according to the temperature and humidity conditions of the working environment to achieve efficient and energy-saving continuous water intake.

[0030] This embodiment provides a high-efficiency and energy-saving adaptive all-weather composite air-water collection device, including a heat pump-driven refrigerant closed loop and a fan-driven air loop. During operation, the heat pump-driven refrigerant closed loop efficiently converts electrical energy into heat and cold energy through a condenser and evaporator. The fan-driven air loop is directly integrated into the heat pump-driven refrigerant closed loop, utilizing the heat and cold released by the condenser and evaporator to collect water from the air. The device can intelligently switch between the most energy-efficient "direct condensation air-water collection" and "adsorption air-water collection" operating modes based on the working environment via a PLC module with integrated energy efficiency algorithms. In the "adsorption air-water collection" mode, by automatically switching the flow path of the heat pump-driven refrigerant closed loop, the device maintains the adsorbent coating on the cooling side in an adsorption state and the adsorbent coating on the heat-releasing side in a desorption state, achieving a highly efficient, continuous, and safe drinking water supply.

[0031] Specifically, the heat pump-driven refrigerant closed loop includes a compressor 1, a second adsorbent-coated heat exchanger 2, an expansion valve 3, a first adsorbent-coated heat exchanger 4, and a four-way diverter valve 5. The first flow port of the four-way diverter valve 5 is connected to the inlet of the compressor 1, the outlet of the compressor 1 is connected to the second flow port of the four-way diverter valve 5, the third flow port of the four-way diverter valve 5 is connected to the top opening of the second adsorbent-coated heat exchanger 2, and the fourth flow port is connected to the top opening of the first adsorbent-coated heat exchanger 4. The bottom openings of the second adsorbent-coated heat exchanger 2 and the first adsorbent-coated heat exchanger 4 are connected through the expansion valve 3, forming a closed loop. The refrigerant circulates within this loop, constituting the heat pump-driven refrigerant closed loop. The four-way diverter valve 5 can be used to reverse the refrigerant flow direction, switching the heat release and cooling states of the second adsorbent-coated heat exchanger 2 and the first adsorbent-coated heat exchanger 4.

[0032] The first adsorbent-coated heat exchanger 4 includes multiple layers of first fins 4-1 and multiple layers of first adsorbent coating 4-2, with each layer of first fins 4-1 loaded with a first adsorbent coating 4-2; the second adsorbent-coated heat exchanger 2 includes multiple layers of second fins 2-1 and multiple layers of second adsorbent coating 2-2, with each layer of second fins 2-1 loaded with a second adsorbent coating 2-2; both the first fins 4-1 and the second fins 4-2 are installed in multiple layers at equal intervals, and the flow pipe is installed between the second adsorbent-coated heat exchanger 2 and the first adsorbent-coated heat exchanger 4 in a bypass manner. Through structural optimization, the heat exchange effect in the second adsorbent-coated heat exchanger 2 and the first adsorbent-coated heat exchanger 4 is enhanced, which is conducive to the uniform and rapid transfer of heat in the adsorbent coating.

[0033] Specifically, the fan-driven air circuit includes a first flow path 6 integrated outside the first adsorbent-coated heat exchanger 4, a second flow path 7 integrated outside the second adsorbent-coated heat exchanger 2, a first water collector 8, a second water collector 9, and an adsorption-type water collection module 10; the first flow path 6 integrated outside the first adsorbent-coated heat exchanger 4 includes a first three-way valve 6-1, a first air filter 6-2, a first inlet air duct 6-3, a first outlet air duct 6-4, a first fan 6-5, and a second three-way valve 6-6; the second flow path 7 integrated outside the second adsorbent-coated heat exchanger 2 includes a third three-way valve 7-1, a second air filter 7-2, a second inlet air duct 7-3, a second outlet air duct 7-4, a second fan 7-5, and a fourth three-way valve 7-6; the adsorption-type water collection module 10 includes a heat exchanger 10-1, a third water collector 10-2, a fifth three-way valve 10-3, and a sixth three-way valve 10-4;

[0034] In the first flow path 6, the first three-way valve 6-1 is connected to the first inlet air duct 6-3 through an air pipe. The inlet air duct of the first inlet air duct 6-3 is equipped with a first air filter 6-2. The first inlet air duct 6-3 and the first outlet air duct 6-4 are directly integrated outside the first adsorbent coating heat exchanger 4. The first outlet air duct 6-4 is connected to the inlet of the first fan 6-5 through an air pipe. The outlet of the first fan 6-5 is connected to the inlet of the second three-way valve 6-6. The two outlets of the second three-way valve 6-6 are respectively connected to the bottom side inlet of the first water collector 8 and the heat exchanger 10-1 in the adsorption water collection module 10.

[0035] In the second flow path 7, the third three-way valve 7-1 is connected to the second inlet air duct 7-3 through an air pipe. The inlet air duct of the second inlet air duct 7-3 is equipped with a second air filter 7-2. The second inlet air duct 7-3 and the second outlet air duct 7-4 are directly integrated outside the second adsorbent coating heat exchanger 2. The second outlet air duct 7-4 is connected to the inlet of the second fan 7-5 through an air pipe. The outlet of the second fan 7-5 is connected to the inlet of the fourth three-way valve 7-6. The two outlets of the fourth three-way valve 7-6 are respectively connected to the second water collector 9 and the other side inlet of the bottom of the heat exchanger 10-1 in the adsorption water collection module 10.

[0036] The third water collector 10-2 in the adsorption water collection module 10 is directly integrated into the bottom of the heat exchanger 10-1. It collects water obtained by the adsorption air water intake mode using gravity. One outlet of the top of the heat exchanger 10-1 is connected to the fifth three-way valve 10-3, and the other outlet is connected to the sixth three-way valve 10-4. The two outlets of the fifth three-way valve 10-3 are connected to the first three-way valve 6-1 and the external environment, respectively. The two outlets of the sixth three-way valve 10-4 are connected to the third three-way valve 7-1 and the external environment, respectively. By adjusting the passage of each three-way valve, the switching between the "direct condensation air water intake" and "adsorption air water intake" operation modes can be achieved.

[0037] Specifically, the adsorption-type water collection module 10 has both heat exchange and water collection functions. In the adsorption-air water collection mode, the high-temperature and high-humidity air flowing out from the second flow path 7 and the low-temperature and low-humidity air flowing out from the first flow path 6 exchange heat in the heat exchanger 10-1. The water vapor in the high-temperature and high-humidity air is condensed into water droplets and falls into the third water collector 10-2 under the action of gravity. The low-temperature and low-humidity air after heat exchange flows into the external environment through the fifth three-way valve 10-3 or the sixth three-way valve 10-4. The high-temperature and high-humidity air after heat exchange flows back to the first flow path 6 or the second flow path 7 through the corresponding sixth three-way valve 10-4 or fifth three-way valve 10-3, and the desorbed but uncondensed water vapor is recirculated.

[0038] Specifically, a water purification module is installed between the second three-way valve 6-6 and the first water collector 8, a water purification module is installed between the fourth three-way valve 7-6 and the second water collector 9, and a water purification module is installed between the heat exchanger 10-1 and the third water collector 10-2. This can effectively prevent impurities such as sand and dust from polluting the water body and achieve a direct supply of safe water.

[0039] Specifically, the first three-way valve 6-1, the second three-way valve 6-6, the third three-way valve 7-1, the fourth three-way valve 7-6, the fifth three-way valve 10-3, and the sixth three-way valve 10-4 are all solenoid valves; the four-way directional valve 5 is a solenoid directional valve; the first three-way valve 6-1, the second three-way valve 6-6, the third three-way valve 7-1, the fourth three-way valve 7-6, the fifth three-way valve 10-3, the sixth three-way valve 10-4, the four-way directional valve 5, the first fan 6-5, the second fan 7-5, and the compressor 1 are all intelligently controlled by a PLC module with integrated energy efficiency algorithms.

[0040] Specifically, the PLC module with integrated energy efficiency algorithm will determine the energy efficiency of different water intake operation modes based on the temperature and humidity conditions of the working environment, and perform intelligent adaptive control on the composite air-water intake device: when the temperature and humidity conditions of the working environment are in the high-efficiency range of the "direct condensation air-water intake" operation mode, the passage of each three-way valve will be adjusted to obtain safe drinking water using the "direct condensation air-water intake" method; when the temperature and humidity conditions of the working environment are in the high-efficiency range of the "adsorption air-water intake" operation mode and the range that is unique to the "adsorption air-water intake" operation mode, the passage of each three-way valve will be adjusted to obtain safe drinking water using the "adsorption air-water intake" method; when the device uses the "adsorption air-water intake mode" to obtain safe drinking water, the four-way diverting valve will be controlled according to the adsorption state of the first adsorbent coating and the second adsorbent coating to always maintain the adsorbent coating on the refrigeration side in the adsorption state and the adsorbent coating on the heat release side in the desorption state, so as to achieve a continuous supply of safe drinking water.

[0041] A highly efficient and energy-saving adaptive all-weather composite air-water intake device includes two operating modes: "direct condensation air-water intake" and "adsorption air-water intake." The working process of each operating mode is described below:

[0042] Specifically, the "direct condensation air-to-water intake" operating mode includes two working paths:

[0043] like Figure 2 As shown, the first flow port of the four-way diverting valve 5 is connected to the fourth flow port, and the second flow port is connected to the third flow port. At this time, the first adsorbent coating heat exchanger 4 acts as the evaporator of the heat pump system, and the second adsorbent coating heat exchanger 2 acts as the condenser of the heat pump system. The first three-way valve 6-1 connects the outside air with the first inlet air duct 6-3. The inlet air duct of the first inlet air duct 6-3 is equipped with a first air filter 6-2. The second three-way valve 6-6 connects the first fan 6-5 and the first water collector 8, and shuts off the second fan 7-5. In this operating path, when the heat pump-driven refrigerant circuit is working, the refrigerant releases cooling energy as it flows through the first adsorbent coating heat exchanger 4. At the same time, the outside air, driven by the first fan 6-5, flows along the first flow path 6 and is condensed as it flows through the first adsorbent coating heat exchanger 4, with the temperature dropping below the dew point, directly generating condensate. The generated condensate is collected by the first water collector 8. The first air filter 6-2 can effectively filter dust and impurities in the air, preventing clogging of the first adsorbent coating 4-2.

[0044] like Figure 3As shown, the first flow port of the four-way diverting valve 5 is connected to the third flow port, and the second flow port is connected to the fourth flow port. At this time, the second adsorbent coating heat exchanger 2 acts as the evaporator of the heat pump system, and the first adsorbent coating heat exchanger 4 acts as the condenser of the heat pump system. The third three-way valve 7-1 connects the outside air to the second inlet air duct 7-3. The inlet air duct of the second inlet air duct 7-3 is equipped with a second air filter 7-2. The fourth three-way valve 7-6 connects the second fan 7-5 and the second water collector 9, and shuts off the first fan 6-5. In this operating path, when the heat pump-driven refrigerant circuit is working, the refrigerant releases cooling energy as it flows through the second adsorbent coating heat exchanger 2. At the same time, the outside air, driven by the second fan 7-5, flows along the second flow path 7 and is condensed as it flows through the second adsorbent coating heat exchanger 2, with the temperature dropping below the dew point, directly generating condensate. The generated condensate is collected by the second water collector 9. The second air filter 7-2 can effectively filter dust and impurities in the air, preventing clogging of the second adsorbent coating 2-2.

[0045] In addition, in the "direct condensation air water intake" operation mode, water vapor in the air will directly condense into droplets on the surface of the first adsorbent coating heat exchanger 4 or the second adsorbent coating heat exchanger. When the droplets fall, they can also clean and rinse the first adsorbent coating 4-2 or the second adsorbent coating 2-2, ensuring that the adsorbent can still maintain its original adsorption-desorption capacity in extremely harsh environments such as sandstorms.

[0046] Specifically, the "adsorption-type air-to-water extraction" operation mode includes two working stages:

[0047] The first working phase is as follows Figure 4 As shown, the first and fourth flow ports of the four-way diverting valve 5 are connected, and the second and third flow ports are connected. In this case, the first adsorbent-coated heat exchanger 4 acts as the evaporator of the heat pump system, and the second adsorbent-coated heat exchanger 2 acts as the condenser of the heat pump system. In the first flow path 6, the first three-way valve 6-1 connects the outside air to the first inlet air duct 6-3. The inlet air duct of the first inlet air duct 6-3 is equipped with a first air filter 6-2. The second three-way valve 6-6 connects to the first fan 6-5. In the heat exchanger 10-1; in the second flow path 7, the third three-way valve 7-1 connects to the sixth three-way valve 10-4 and the second inlet air duct 7-3, the inlet air duct of the second inlet air duct 7-3 is equipped with a second air filter 7-2, and the fourth three-way valve 7-6 connects to the second fan 7-5 and the heat exchanger 10-1; in the adsorption water collection module 10, the fifth three-way valve 10-3 connects to the heat exchanger 10-1 and the external environment, and the sixth three-way valve 10-4 connects to the heat exchanger 10-1 and the third three-way valve 7-1.

[0048] During this working phase, when the refrigerant circuit driven by the heat pump is working, the low-temperature and low-pressure refrigerant flows into the first adsorbent coating heat exchanger 4 through the expansion valve 3 and releases cold energy to the outside. At this time, the first adsorbent coating 4-2 loaded on the first fin 4-1 is cooled by the air flowing through it, resulting in an increase in relative humidity and easier removal of adsorbed heat. It can more easily capture water vapor in the air. The refrigerant flowing out of the first adsorbent coating heat exchanger 4 becomes relatively high-temperature and high-pressure after passing through the compressor 1. It flows into the second adsorbent coating heat exchanger 2 through the refrigerant pipeline and releases heat to the outside. At this time, the second adsorbent coating 2-2 loaded on the second fin 2-1 absorbs heat and drives the adsorbent to desorb and release water vapor.

[0049] Meanwhile, outside air along the first flow path 6 is cooled as it flows through the first adsorbent coating heat exchanger 4 driven by the first fan 6-5, and water vapor is adsorbed by the first adsorbent coating 4-2. Finally, the low-temperature and low-humidity air flows into the heat exchanger 10-1. The first air filter 6-2 can effectively filter dust and impurities in the air, preventing blockage of the first adsorbent coating 4-2. Air along the second flow path 7 is heated as it flows through the second adsorbent coating heat exchanger 2 driven by the second fan 7-5, and water vapor released by the desorption of the adsorbent is carried away. Finally, the high-temperature and high-humidity air flows into the heat exchanger 10-1. The second air filter 7-2 can effectively filter dust and impurities in the air, preventing blockage of the second adsorbent coating 2-2.

[0050] In the adsorption-type water collection module, the high-temperature and high-humidity air flowing out from the second flow path 7 and the low-temperature and low-humidity air flowing out from the first flow path 6 exchange heat in the heat exchanger 10-1. The water vapor in the high-temperature and high-humidity air is condensed into water droplets and falls into the third water collector 10-2 under the action of gravity. The low-temperature and low-humidity air after heat exchange flows into the external environment through the fifth three-way valve 10-3, and the high-temperature and high-humidity air after heat exchange flows back to the second flow path 7 through the sixth three-way valve 10-4, recirculating the desorbed but uncondensed water vapor.

[0051] The second working phase, as follows Figure 5As shown, the first and third flow channels of the four-way diverting valve 5 are connected, and the second and fourth flow channels are connected. In this case, the second adsorbent-coated heat exchanger 2 acts as the evaporator of the heat pump system, and the first adsorbent-coated heat exchanger 4 acts as the condenser of the heat pump system. In the first flow path 6, the first three-way valve 6-1 connects to the fifth three-way valve 10-3 and the first inlet air duct 6-3. The inlet air duct of the first inlet air duct 6-3 is equipped with a first air filter 6-2. The second three-way valve 6-6 connects to the first… Fan 6-5 and heat exchanger 10-1; in the second flow path 7, the third three-way valve 7-1 connects the outside air with the second inlet air duct 7-3, the inlet air duct of the second inlet air duct 7-3 is equipped with a second air filter 7-2, and the fourth three-way valve 7-6 connects the second fan 7-5 and heat exchanger 10-1; in the adsorption water collection module 10, the fifth three-way valve 10-3 connects the heat exchanger 10-1 and the first three-way valve 6-1, and the sixth three-way valve 10-4 connects the heat exchanger 10-1 and the outside environment.

[0052] During this working phase, when the refrigerant circuit driven by the heat pump is working, the low-temperature and low-pressure refrigerant flows into the second adsorbent coating heat exchanger 2 through the expansion valve 3 and releases cold energy to the outside. At this time, the second adsorbent coating 2-2 loaded on the second fin 2-1 is cooled by the air flowing through it, resulting in an increase in relative humidity and easier removal of adsorbed heat. It can more easily capture water vapor in the air. The refrigerant flowing out of the second adsorbent coating heat exchanger 2 becomes relatively high-temperature and high-pressure after passing through the compressor 1. It flows into the first adsorbent coating heat exchanger 4 through the refrigerant pipeline and releases heat to the outside. At this time, the first adsorbent coating 4-2 loaded on the first fin 4-1 absorbs heat and drives the adsorbent to desorb and release water vapor.

[0053] Meanwhile, the outside air along the second flow path 7, driven by the second fan 7-5, is cooled as it flows through the second adsorbent coating heat exchanger 2, and water vapor is adsorbed by the second adsorbent coating 2-2. Finally, the low-temperature and low-humidity air flows into the heat exchanger 10-1. The second air filter 7-2 can effectively filter dust and impurities in the air, preventing clogging of the second adsorbent coating 2-2. The air along the first flow path 6, driven by the first fan 6-5, is heated as it flows through the first adsorbent coating heat exchanger 4, and at the same time, it carries away the water vapor released by the desorption of the adsorbent. Finally, the high-temperature and high-humidity air flows into the heat exchanger 10-1. The first air filter 6-2 can effectively filter dust and impurities in the air, preventing clogging of the first adsorbent coating 4-2.

[0054] In the adsorption-type water collection module, the high-temperature and high-humidity air flowing out from the first flow path 6 and the low-temperature and low-humidity air flowing out from the second flow path 7 exchange heat in the heat exchanger 10-1. The water vapor in the high-temperature and high-humidity air is condensed into water droplets and falls into the third water collector 10-2 under the action of gravity. The low-temperature and low-humidity air after heat exchange flows into the external environment through the sixth three-way valve 10-4, and the high-temperature and high-humidity air after heat exchange flows back to the first flow path 6 through the fifth three-way valve 10-4, recirculating the desorbed but uncondensed water vapor.

[0055] The first three-way valve 6-1, the second three-way valve 6-6, the third three-way valve 7-1, the fourth three-way valve 7-6, the fifth three-way valve 10-3, the sixth three-way valve 10-4, the four-way diverting valve 5, the first fan 6-5, the second fan 7-5, and the compressor 1 are all intelligently controlled by a PLC module with integrated energy efficiency algorithms according to the working environment, realizing the automatic switching of various operating modes and working stages.

[0056] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
