Description

ATMOSPHERIC WATER GENERATIONTECHNICAL FIELD

[0001] The disclosure relates generally to atmospheric water generation systems. In particular, the disclosure relates to an atmospheric water generation system comprising a cooling condensation circuit and a desiccant circuit.BACKGROUND

[0002] Access to clean water is a global challenge, particularly in regions facing water scarcity. Atmospheric water generation (AWG) systems are designed to extract water from ambient air in order to produce potable water. AWG systems are utilised across a broad range of applications where access to safe drinking water is essential. AWG systems are typically based on either cooling condensation technology or desiccant technology.

[0003] In AWG systems based on cooling condensation technology, air is cooled below its dew point and subsequently condensed such that liquid water droplets are formed. In AWG systems based on desiccant technology, a desiccant is used to capture water vapour from the air. A desiccant is a hygroscopic material and may be classified as a dry desiccant, which is a porous, solid material such as silica gels configured to adsorbs moisture from air, or a wet desiccant, which is a liquid hygroscopic material such as a lithium chloride solution configured to absorb moisture from air. The water vapour is then regenerated from the desiccant through heating and subsequently condensed into liquid water.

[0004] Existing AWG systems may be effective in certain conditions, but face limitations when operated in environments that provide operational parameters outside of their optimal range. It is therefore desired to develop a solution for extracting water from ambient air that addresses or at least mitigates some of these issues.SUMMARY

[0005] An object of the present disclosure is to provide systems, methods and other approaches for efficiently extracting water from air in a variety of different climatic conditions. More specifically, one object of the disclosure is to combine a cooling condensation system and a desiccant system into a hybrid AWG system, controlledby a control system configured to determine operational parameters for each of the systems based on acquired data relating to parameters affecting operation of the systems. In this way, the hybrid AWG system is enabled to effectively generate water in a range of climates and operating conditions.

[0006] In a first aspect, a hybrid AWG system is provided. The hybrid AWG system comprises a cooling condensation circuit comprising a first air intake and a condenser configured to extract water from ambient air, a desiccant circuit comprising a second air intake and a desiccant configured to absorb water from ambient air, at least one fan for causing the ambient air to enter the first air intake and the second air intake, and a control system comprising processing circuitry. The control system is configured to acquire data relating to one or more parameters affecting operation of the cooling condensation circuit and the desiccant circuit, determine control parameters for each of the cooling condensation circuit and the desiccant circuit based on the acquired data, and control operation of each of the cooling condensation circuit and the desiccant circuit based on the respective determined control parameters.

[0007] By combining a cooling condensation circuit and a desiccant circuit into one system, the hybrid AWG system takes advantage of the benefits provided by each circuit and enables water to be efficiently generated from humid air across a wide range of climatic conditions. The control system further enables the hybrid AWG system to dynamically adapt to varying climatic conditions and demands, such that a reliable and efficient water production is ensured.

[0008] In some variants, the processing circuitry is configured to cause the cooling condensation circuit and the desiccant circuit to operate simultaneously based on the determined control parameters by enabling an airflow into each of the first and second air intakes. Operating both systems simultaneously is beneficial in situations where for example a sudden increase in water production rate is desired. In some variants, the processing circuitry is further configured to control a degree to which each of the cooling condensation circuit and the desiccant circuit operate based on the determined control parameters by controlling a degree to which each of the first and second air intakes are opened, controlling an airflow from the desiccant circuit to the cooling condensation circuit by controlling a valve between the desiccant circuit and the cooling condensation circuit, and / or controlling parameters relating to the condenser and the desiccant respectively. This is beneficial as it allows the hybrid AWG systemto adapt the degree to which each circuit contributes to the generation of water depending on the current climatic conditions.

[0009] In some variants, the processing circuitry is configured to cause operation of the cooling condensation circuit only, based on the determined control parameters, by controlling the first air intake to be in an at least partially opened position, and controlling the second air intake to be in a closed position and / or causing a valve between the desiccant circuit and the cooling condensation circuit to be closed. This is beneficial when current climatic conditions are favourable for generating water using cooling condensation technology.

[0010] In some variants, the processing circuitry is configured to cause operation of the desiccant circuit only, based on the determined control parameters, controlling the second air intake to be in an at least partially opened position, controlling the first air intake to be in a closed position, and optionally causing a valve between the desiccant circuit and the cooling condensation circuit to be opened. This is beneficial when current climatic conditions are favourable for generating water using desiccant technology.

[0011] In some variants, the hybrid AWG system further comprises a sensor system configured to acquire sensor data relating to one or more parameters affecting operation of the cooling condensation circuit and / or the desiccant circuit and provide the acquired sensor data to the control system. In this way, the control system is enabled to control the hybrid AWG system based on current conditions. The sensor data may relate to at least one of a temperature of one or more components of the hybrid AWG system, a temperature of air inside the hybrid AWG system, an humidity of air inside the hybrid AWG system, a water content of the desiccant, an air flow rate inside the hybrid AWG system, a water flow rate inside the hybrid AWG system, a speed of the fan, a current level of water in a tank of the hybrid AWG system, an ambient temperature, an ambient air humidity and an atmospheric pressure.

[0012] In some variants, the acquired data relates to one or more of a rate of water generation of the hybrid AWG system, a power usage of the hybrid AWG system, a water demand from the hybrid AWG system, and weather forecast data. In this way, the control system is enabled to control the hybrid AWG system based on current operational parameters of the hybrid AWG system and current and forecast weather data. The processing circuitry may further be configured to generate a prediction of atleast one of a future water demand, a future power usage, and future weather conditions based on the acquired data and determine the control parameters based on the prediction. In this way, the control system is enabled to control the hybrid AWG system based on both current and projected water demand, power usage and / or weather conditions.

[0013] In some variants, the processing circuitry is configured to determine the control parameters based on an objective, comprising one or more of optimising water production, reducing cost of operation and reducing energy consumption. This enables the control system to tailor the control parameters for, for example, energy efficient operation. To this end, the control parameters may comprise a timeframe for operating the cooling condensation circuit and / or the desiccant circuit, for example to postpone operation of the hybrid AWG system until conditions are desirable for efficient water generation.

[0014] In some variants, the processing circuitry is configured to determine the control parameters using a machine learning algorithm. This is beneficial as the machine learning algorithm and other artificial intelligence approaches can identify patterns and relationships that influence the efficiency of the hybrid AWG system and continuously learn from new input data, thereby enabling the hybrid AWG system to adapt dynamically to varying conditions and demands.

[0015] In some variants, the processing circuitry is configured to control the cooling condensation circuit to extract water by controlling the first air intake to be in an at least partially open position, operating the at least one fan to draw air into the first air intake, and operating the condenser to extract water from air drawn into the first air intake. In this way, an airflow is enabled through the cooling condensation circuit and water is enabled to be generated. In some variants, the processing circuitry is further configured to determine control parameters for the condenser. In this way, the cooling capacity of the condenser and thus the amount of water that may be generated by the cooling condensation circuit may be controlled.

[0016] In some variants, the processing circuitry the processing circuitry is configured to control the desiccant circuit to extract water by controlling the second air intake to be in an at least partially open position and operating the at least one fan to draw air into the second air intake such that the desiccant absorbs water from the air.In this way, an airflow is enabled through the desiccant condensation circuit such that water can be generated.

[0017] In some variants, the desiccant circuit further comprises a heating device configured to heat the desiccant such that the absorbed water is evaporated into humid air. This allows the desiccant to be regenerated when saturated. In some variants, the processing circuitry is configured to cause the humid air to be input to the condenser and operate the condenser to extract water from the humid air. In this way, the condenser may be used as a cooling component during the regeneration process.

[0018] In some variants, the hybrid AWG system further comprising a compressor and a heat exchanger, wherein the compressor is configured absorb heat from components of the hybrid AWG system using a coolant gas and transfer the heat to the heat exchanger, and the heat exchanger is configured to dissipate the heat. This is beneficial as it enables heat to be transported from heat generating components of the hybrid AWG system which enables efficient operation of each of the desiccant circuit and the cooling condensation circuit.

[0019] In some variants, the hybrid AWG system further comprises a heat recovery system configured to recover heat generated by components of the cooling condensation circuit and / or the desiccant circuit, and use the recovered heat in the desiccant circuit, store it or release it into ambient air. This is beneficial as it increases the efficiency of the hybrid AWG system by capturing and utilizing waste heat generated by components of the hybrid AWG system.

[0032] The detailed description set forth below provides information and embodiments of the disclosed technology with reference to the accompanying drawings. The invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the invention, such as it is defined in the appended claims, to those skilled in the art.

[0033] Access to clean water is a global challenge, particularly in regions facing water scarcity. Atmospheric Water Generation (AWG) systems offer a promising solution by extracting moisture from air. AWG systems are utilized across a broad range of applications where access to safe drinking water is essential. However, existing AWG technologies face significant limitations, as they are dependent on specific climatic conditions to efficiently generate water.

[0034] For example, systems based on cooling condensation require environments with high humidity and relatively low air temperatures to efficiently condense humid air into water. The air in such environments contains sufficient moisture to be efficiently condensed when cooled, while the energy required to cool the air is comparatively low. In comparison, in low-humidity or high-temperature environments, these systemsbecome energy-intensive and inefficient as the energy required to cool the warm air is high, while the water production from the low-humidity air is minimal.

[0035] Desiccant systems, on the other hand, are efficient at absorbing moisture in environments with low humidity and high air temperatures, such as arid regions. In these climates, the air typically contains a significant amount of water vapour even if the relative humidity is low and desiccant materials are highly efficient at absorbing water vapour in these conditions. Desiccant systems exhibit limitations in climates where the air contains less moisture for the desiccant to absorb, such as in cold and dry climates. However, desiccant systems may be more effective than cooling condensation systems in cold climates, as the desiccant can absorb small amounts of water vapour from the cold air over time and the condensation phase of regenerating the desiccant requires a lower temperature difference compared to condensation in a cooling condensation system. However, the process is energy intensive and requires a significant heat input to release the moisture from the desiccant and condense it. Additionally, the desiccant's absorption efficiency decreases at lower temperatures. Further, desiccant systems are less effective in climates with very high humidity where the desiccant quickly gets saturated and frequent regeneration is required, which leads to high energy consumption.

[0036] Consequently, current AWG solutions fail to operate efficiently across a range of climates, which limit their functionality. Specifically, current solutions struggle to perform efficiently when confronted with varying climatic conditions.

[0037] Relative humidity is a measure of the amount of water vapour present in air compared to the maximum amount of water vapour the air can hold at a given temperature. A higher relative humidity means that the air contains more moisture relative to its capacity at a given temperature compared to air with a lower relative humidity. Thus, a higher relative humidity of the ambient air enables a larger volume of water to be generated from the air.

[0038] Relative humidity is affected by temperature. As air warms up, its capacity to hold water vapour increases. Consequently, air that is warmed up will have a lower relative humidity than cooler air if its moisture content remains constant. Conversely, cooling the air will increase its relative humidity. Air may be cooled until it reaches its dew point. The dew point is the temperature at which air becomes saturated with water vapour, meaning it can no longer hold all the moisture it contains. When air is cooledto its dew point, the excess water vapour condenses into liquid. The dew point is directly related to the amount of moisture in the air, wherein a high dew point indicates high moisture content and humid conditions, and a low dew point indicates dry air and lower moisture levels.

[0039] Relative humidity is also affected by pressure. At higher altitudes or in lower- pressure environments, the capacity of air to hold moisture decreases. Further, changes in atmospheric conditions, such as rain and wind, will also influence the relative humidity of air.

[0040] The temperature of the ambient air also plays a crucial role in the efficiency of an AWG system. As discussed above, temperature affects the air’s capacity to hold moisture. Further, when water is generated from air in a system based on cooling condensation technology, the air must be cooled to a temperature below its dew point to initiate condensation. Consequently, a higher air temperature will require more energy for cooling. In contrast, in a system based on desiccant technology, a higher air temperature may be beneficial as the air temperature influences the desiccant’s absorption efficiency, with warmer air often enhancing moisture uptake.

[0041] To remedy this, a hybrid AWG system is proposed for efficiently extracting water from humid air in a variety of different climatic conditions by combining cooling condensation technology and desiccant technology into one system. The hybrid AWG system comprises a cooling condensation circuit and a desiccant circuit which can be operated separately (i.e. using the cooling condensation circuit or the desiccant circuit only) as well as in combination. The operation of the circuits is controlled by a control system configured to determine appropriate (e.g. optimal) operational parameters for each of the circuits based on acquired data relating to parameters affecting operation of the circuits. In this way, a hybrid AWG system is capable of effectively generating water in a range of climates and operating conditions, such that reliable and efficient water production is ensured regardless of local and current weather conditions.

[0042] FIG. 1 is a schematic view of a hybrid AWG system 100 according to an example. The hybrid AWG system 100 comprises a cooling condensation circuit 110 and a desiccant circuit 120. The cooling condensation circuit 110 is configured to extract water from air using a condenser 140. The desiccant circuit 120 is configured to extract water from air using a desiccant 150a. The hybrid AWG system 100 utilizes ambient air as a source of moisture for generating water. Ambient air is understood tomean air outside of the hybrid AWG system 100 in the environment around the hybrid AWG system 100. The properties of the ambient air, including its temperature and relative humidity, impact the performance and efficiency of the cooling condensation circuit 110 and the desiccant circuit 120 to extract water from the air.

[0043] As discussed above, the properties of the ambient air will directly affect the efficiency of each of the cooling condensation circuit 110 and the desiccant circuit 120 to generate water from the air. High-humidity and moderate temperature environments are preferred for the cooling condensation circuit 110, as the air contains a lot of moisture and the energy required to cool the air is low. Low-humidity and high- temperature environments are less ideal for the cooling condensation circuit 110, as the air contains less moisture and requires more energy for cooling. For the desiccant circuit 120, dry and warm climates provide preferred conditions, as the desiccant is effective at absorbing moisture from warm and dry air. The desiccant circuit 120 becomes less efficient in humid conditions, where the desiccant may quickly become saturated, and the energy required for desiccant regeneration increases. Consequently, depending on environmental conditions and the properties of the ambient air, operation of either the cooling condensation circuit 110, the desiccant circuit 120 or a combination of the two, may provide the best option for efficiently generating water from the ambient air. Operation of each of the cooling condensation circuit 110 and the desiccant circuit 120, alone and in combination, will be discussed in detail in relation to FIG. 2.

[0044] During operation of the hybrid AWG system 100, the ambient air is drawn into the hybrid AWG system 100 through at least one air intake. In some examples, the cooling condensation circuit 110 comprises a first air intake 130a and the desiccant circuit 120 comprises a second air intake 130b. Each of the first and second air intakes 130a, 130b are controllable to be in an opened, closed, or partially opened position, in order to control how much air is received by the respective air intake. The air intakes 130a, 130b are controlled to be opened or closed by a control mechanism such as an actuator-controlled shutter or a motorized valve, configured to open or close the air intakes 130a, 130b in response to signals from a control unit.

[0045] In some examples, the hybrid AWG system 100 further comprises a valve 180 between the cooling condensation circuit 110 and the desiccant circuit 120, configured to enable an airflow between the desiccant circuit 120 to the coolingcondensation circuit 110, for example from the desiccant circuit 120 to the cooling condensation circuit 110.

[0046] The hybrid AWG system 100 further comprises at least one fan 160, positioned downstream of the cooling condensation circuit 110 and the desiccant circuit 120. By means of the at least one fan 160, the ambient air is drawn into at least one of the first and second air intakes 130a, 130b, depending on whether the respective air intakes 130a, 130b are in the opened, closed or partially opened position. The ambient air is thereby conveyed into at least one of the cooling condensation circuit 110 and the desiccant circuit 120. As such, the least one fan 160 is suitable for causing ambient air to enter the first air intake 130a and the second air intake 130b. In some examples, one fan 160 is used to control air into each of the first and second air intake 130a, 130b. Having a single fan reduces the system complexity and allows for a more compact hybrid AWG system 100. In some examples, a first fan is used to control airflow into the first air intake 130a and a second fan is used to control airflow into the second air intake 130b. Having a separate fan for each circuit 110, 120 enables the airflow into each circuit 110, 120 to be controlled individually based on the requirements of the circuit.

[0047] By controlling the speed and power of the at least one fan 160, the volume and flow rate of air entering the hybrid AWG system 100 may be regulated to provide the appropriate (e.g. optimal) conditions for the hybrid AWG system 100 to generate water. In the cooling condensation circuit 110, the volume of air entering the circuit is related to the volume of water which may be generated from the volume of air, with a larger volume of air enabling a larger volume of water to be condensed. In the desiccant circuit 120, the flow rate of the air entering the circuit determines the exposure of the air to the desiccant, wherein a slower airflow allows more time for the desiccant 150a to absorb moisture, which may increase the efficiency of the desiccant circuit 120. Further, the at least one fan 160 may be controlled to provide a consistent air pressure and airflow rate through the hybrid AWG system 100, enhancing overall system efficiency and water production.

[0048] Ambient air drawn in through the first air intake 130a of the cooling condensation circuit 110 will be conveyed to the condenser 140 of the cooling condensation circuit 110. The condenser 140 is configured to cool the air below its dew point and condense the water vapour contained in the air such that liquid wateris formed, as known in the art. The cooling capacity of the condenser 140 may be controlled by controlling an amount of refrigerant flowing through the condenser 140. The condensed water is then collected and directed to a storage tank (not shown) of the hybrid AWG system 100.

[0049] Ambient air drawn in through the second air intake 130b of the desiccant circuit 120 will be conveyed to the desiccant 150a of the desiccant circuit 120. The desiccant 150a is configured to absorb or adsorb water vapour contained in the air, as known in the art. In some examples, the desiccant 150a is a wet desiccant. The desiccant 150a may be a dry desiccant, such as silica gel, configured to adsorbs moisture from air, or a wet desiccant, which is a liquid hygroscopic material such as a lithium chloride solution configured to absorb moisture from air brought into contact with the wet desiccant. In some examples the wet desiccant is a concentrated saline solution. The efficiency of the desiccant 150a to absorb water vapour may be controlled by controlling its temperature, as desiccant temperature affects the rate of moisture uptake.

[0050] In one example, the desiccant circuit 120 further comprises a heating device 150b configured to heat the desiccant 150a such that the absorbed water is evaporated into humid air in a regeneration process. The regeneration process may thus be controlled by controlling the temperature of the heating device 150b, such that moisture release is balanced with energy usage. After the absorbed water has been evaporated into humid air, the humid air is conveyed to a cooling component. In some examples, the cooling component is the condenser 140 of the cooling condensation circuit 110, to which the humid air may be conveyed via operation of the valve 180. In some examples, the surrounding environment is used as the cooling component, as the water vapour released from the heated desiccant 150a will be at a higher temperature than the surrounding environment. Therefore, as the warm water vapour comes into contact with a cooling surface in the surrounding environment, heat will be transferred to the cooler environment such that the temperature of the water vapour is lowered to its dew point, causing the water vapour to condense into liquid water. By condensing the moisture contained in the humid air using a cooling component, water is generated by the desiccant circuit 120 and subsequently collected in a storage tank of the hybrid AWG system 100.

[0051] In some examples, the hybrid AWG system 100 further comprises a compressor 190b and a heat exchanger 190a positioned downstream of the condenser 140 and the desiccant 150a, configured to transfer heat from heat generating components of the hybrid AWG system 100. The compressor 190b uses a coolant gas to absorb heat from the heat generating components and then transports the heat to the heat exchanger 190a, where the heat is dissipated. By effectively transporting heat, the compressor 190b and heat exchanger 190a enable efficient operation of both the cooling condensation circuit 110 and the desiccant circuit 120.

[0052] In one example, the hybrid AWG system 100 further comprises a heat recovery system (not shown) configured to recover heat generated by components of the cooling condensation circuit 110 and / or the desiccant circuit 120. The heat recovery system increases the efficiency of the hybrid AWG system 100 by capturing and utilizing waste heat generated by components of the hybrid AWG system 100, for example the condenser 140 or the compressor 190a. The recovered heat may then be used for the regeneration process of the desiccant 150a. This reduces the need for operating the heating device 150b and thus increases energy efficiency of the hybrid AWG system 100. If the recovered heat is not needed to regenerate the desiccant 150a, it can be stored for later use or released into ambient air in order to optimize cooling processes of the hybrid AWG system 100 during warmer conditions.

[0053] The hybrid AWG system 100 further comprises a control system 170 comprising processing circuitry 175. The control system 170 is communicatively coupled (not shown) to the components of the hybrid AWG system 100, allowing the control system 170 to control operation of the hybrid AWG system 100 and its components. For example, the control system 170 is configured to control the first and second air intakes 130a, 130b to be in an opened, closed or partially opened position, to control the cooling capacity of the condenser 140, to control the amount of heat provided by the heating device 150b, to control the speed and power of the at least one fan 160, to control the valve 180 to be in an opened, closed or partially opened position, and / or to control the operation of the heat exchanger 190a and the compressor 190b. The modes of operation of the hybrid AWG system 100 by means of the control system 170 will be discussed in more detail in relation to FIG. 2.

[0054] The control system 170 may further be communicatively coupled to systems configured to provide various forms of input data to the control system 170. Thesystems may be internal or external to the hybrid AWG system 100. In one example, the control system 170 is coupled to a sensor system of the hybrid AWG system 100. The sensor system is configured to acquire sensor data relating to one or more parameters affecting operation of the cooling condensation circuit 110 and / or the desiccant circuit 120, and to provide the acquired sensor data to the control system 170. For example, the sensor data may relate to properties of the ambient air. In one example, the control system 170 is coupled to a monitoring system configured to provide input data relating to the operation of the hybrid AWG system 100, for example a current rate of water generation of the AWG system 100. In one example, the control system 170 is coupled to an external system configured to provide input data relating current and forecast weather. The various input data acquired by the control system 170 will be discussed in more detail in relation to FIG. 3.

[0055] The control system 170 may be communicatively coupled to various components and systems in any suitable way, for example via a circuit or any other wired, wireless, or network connection known in the art. Furthermore, the communicative coupling may be implemented as a direct connection between the control system 170 and the component(s) or system(s), or may be implemented as a connection via one or more intermediate entities.

[0056] Based on the acquired data, the control system 170 determines control parameters for each of the cooling condensation circuit 110 and the desiccant circuit 120. The control system 170 is further configured to control operation of each of the cooling condensation circuit 110 and the desiccant circuit 120 based on the determined control parameters. The control parameters may include, for example, one or more of a position of the first and / or second air intake 130a, 130b (e.g. a percentage to which the respective intake is open), a cooling capacity of the condenser 140, an amount of heat provided by the heating device 150b (e.g. percentage activation of the heating device 150b), a speed and / or power of the at least one fan 160, a position of the valve 180 (e.g. a percentage to which the valve 180 is open), a percentage activation of a compressor cycle of the compressor 190b, and a percentage activation of a coolant flow in the compressor 190b.

[0057] FIG. 2 is a schematic view of the different modes of operation of the hybrid AWG system 100. As discussed above, the hybrid AWG system 100 may be operated to extract water from air using the cooling condensation circuit 110 only, the desiccantcircuit 120 only, or each of the cooling condensation circuit 110 and the desiccant circuit 120 in combination. The mode of operation that is activated may be controlled by controlling each of the first and second air intakes 130a, 130b to be opened, closed or partially opened, such that ambient air is allowed to enter either the cooling condensation circuit 110 only, the desiccant circuit 120 only, or both circuits simultaneously.

[0058] In a first mode of operation, the control system 170 is configured to cause the cooling condensation circuit 110 and the desiccant circuit 120 to operate simultaneously. This is achieved by controlling each of the first and second air intakes 130a, 130b to be at least partially opened (e.g. fully opened), such that an airflow is enabled into each of the first and second air intakes 130a, 130b when the at least one fan 160 is operated. As discussed above, the least one fan 160 is suitable for causing ambient air to enter the first air intake 130a and the second air intake 130b. In this way, an airflow 210 will enter the first air intake 130a and an airflow 220 will enter the second air intake 130b.

[0059] In the condensation circuit 110, the airflow 210 will be conveyed through the first air intake 130a to the condenser 140 by means of which the temperature of the airflow 210 is cooled below its dew point, causing moisture contained in the air to condense into liquid form. In the desiccant circuit 120, the airflow 220 will be conveyed through the second air intake 130b to the desiccant 150a, by means of which moisture contained in the air will be absorbed, such that it may be regenerated through heating and subsequently condensed into liquid water.

[0060] In examples wherein the hybrid AWG system 100 comprises a separate fan 160a, 160b for each circuit, airflow 210 is drawn into the first air intake 130a and through the cooling condensation circuit 110 by operation of fan 160a. Airflow 220 is drawn into the second air intake 130b and through the desiccant circuit 120 by operation of fan 160b, which is shown as airflow 220a in FIG. 2.

[0061] In an embodiment wherein the hybrid AWG system 100 comprises a single fan 160, an airflow is drawn through each of the cooling condensation circuit 110 and the desiccant circuit 120 by operation of the single fan 160. As discussed above, the least one fan 160 is suitable for causing ambient air to enter the first air intake 130a and the second air intake 130b. In this case, airflow 210 is drawn into the first air intake 130a and through the cooling condensation circuit 110 by operation of fan 160, similarto when fan 160a is operated as described above. Airflow 220 is drawn into the second air intake 130b, through the desiccant 150 and further through valve 180, which has been controlled to be at least partially opened. Valve 180 thereby enables the airflow 220 to be conveyed through the desiccant circuit 120 by the fan 160. In some examples, airflow 220 is conveyed through the valve 180 and into an outlet conduit shared with the cooling condensation circuit 110, which is shown as airflow 220c in FIG. 2. In some examples, airflow 220 is conveyed through the valve 180 and through the condenser 140 of the cooling condensation circuit 110, which is shown as airflow 220b in FIG. 2. By use of valve 180, the single fan 160 is thus enabled to draw air through both the cooling condensation circuit 110 and the desiccant circuit 120.

[0062] As discussed above, the control system 170 is configured to control operation of each of the cooling condensation circuit 110 and the desiccant circuit 120 based on determined control parameters. In particular, the control system 170 may be configured to control a degree to which each of the cooling condensation circuit 110 and the desiccant circuit 120 operate based on the determined control parameters. This may be achieved by controlling the degree to which each of the first and second air intakes 130a, 130b are opened, and thereby the amount of air conveyed into each of the cooling condensation circuit 110 and the desiccant circuit 120. Further, in the case where a single fan 160 is used as discussed above, the degree to which the valve 180 is opened may be controlled to determine how much airflow is enabled through the desiccant circuit 120.

[0063] The control system 170 may further control the degree to which each of the circuits 110, 120 operate by controlling parameters relating to the respective active components of the respective circuits 110, 120. For example, the control system 170 may control the cooling power of the condenser 140 of the cooling condensation circuit 110, or the heat applied to the desiccant 150a of the desiccant circuit 120 during regeneration by the heating device 150b. In this way, the degree to which each circuit 110, 120 contributes to the generation of water by the hybrid AWG system 100 is controlled based on the determined control parameters. For example, by increasing the cooling capacity of the condenser 140, the cooling condensation circuit 110 is controlled to condense more water, and by increasing the heat provided by the heating device 150b, the desiccant circuit 120 is controlled to regenerate more water vapour.

[0064] Operating the cooling condensation circuit 110 and the desiccant circuit 120 simultaneously may be an option if, for example, acquired data indicate that an increase in water production rate is needed to meet a growing demand, while the current climatic conditions allow both the cooling condensation circuit 110 and the desiccant circuit 120 to operate efficiently. In this way, simultaneous operation of the cooling condensation circuit 110 and the desiccant circuit 120 can boost water production to meet spikes in demand.

[0065] In a second mode of operation, the control system 170 is configured to cause operation of the cooling condensation circuit 110 only, based on the determined control parameters. In examples wherein the hybrid AWG system 100 comprises a single fan 160, this is achieved by controlling the first air intake 130a to be in an at least partially opened position such that airflow 210 is enabled into the first air intake 130a and through the cooling condensation circuit 110, while an airflow through the desiccant circuit 120 is prevented by controlling the second air intake 130b to be in a closed position, and / or controlling the valve 180 between the desiccant circuit 120 and the cooling condensation circuit 110 to be closed. As such, even though the least one fan 160 is suitable for causing ambient air to enter the first air intake 130a and the second air intake 130b, it will not do so when the second air intake 130b is closed. In examples wherein the hybrid AWG system 100 comprises a separate fan 160a, 160b for each circuit, the second fan 160b may not be operated.

[0066] In the second mode of operation, the control system 170 may further control the operation of the cooling condensation circuit 110 by controlling the degree to which the first air intake 130a is opened, the cooling power of the condenser 140, and the operation of the at least one fan 160. In this way, the operation of the cooling condensation circuit 110 to generate water from air may be controlled based on the determined control parameters.

[0067] Operating the cooling condensation circuit 110 only may be an option if, for example, acquired sensor data indicate that the ambient air has a high relative humidity and a relatively low temperature. These conditions allow the cooling condensation circuit 110 to efficiently generate water, while they are less appropriate for the desiccant circuit 120.

[0068] In a third mode of operation, the control system 170 is configured to cause operation of the desiccant circuit 120 only, based on the determined controlparameters. In examples wherein the hybrid AWG system 100 comprises a single fan 160, this is achieved by controlling the first air intake 130a to be in a closed position, such that an airflow through the cooling condensation circuit 110 is prevented, while the second air intake 130b and the valve 180 are controlled to be in an at least partially opened position, such that airflow 220 is enabled into the second air intake 130b, through the valve 180, and further conveyed either as airflow 220c into an outlet conduit shared with the cooling condensation circuit 110 or as airflow 220b through the condenser 140 of the cooling condensation circuit 110, as discussed above. It is noted that conveying airflow 220b or 220c through conduits or components shared with the cooling condensation circuit 110 in this way is not considered to involve operating the cooling condensation circuit 110. As such, even though the least one fan 160 is suitable for causing ambient air to enter the first air intake 130a and the second air intake 130b, it will not do so when the first air intake 130a is closed. In examples wherein the hybrid AWG system 100 comprises a separate fan 160a, 160b for each circuit, the first fan 160a may not be operated.

[0069] In the third mode of operation, the control system 170 may further control the operation of the desiccant circuit 120 by controlling the degree to which the second air intake 130b and optionally the valve 180 is opened, and the amount of heat provided by the heating device 150b to heat the desiccant 150a during regeneration. In this way, the operation of the desiccant circuit 120 to generate water from air is controlled based on the determined control parameters.

[0070] Operating the desiccant circuit 110 only may be an option if for example acquired sensor data indicate that the ambient air has a low relative humidity and a high temperature. These conditions allow the desiccant circuit 120 to efficiently generate water, while they are less appropriate for the cooling condensation circuit 110. As discussed above, in some examples, operation of the desiccant circuit 120 may comprise feeding air through the condenser 140. In such embodiments, if the first air intake 130a is controlled to be in a closed position, the cooling condensation circuit 110 is not considered to be operational, even though the condenser 140 is in use. In these examples, the control system 170 may further control the cooling power of the condenser 140 to extract water from the humid air.

[0071] By provision of the control system 170, the hybrid AWG system 100 is enabled to dynamically switch between operation of the cooling condensation circuit110 and the desiccant circuit 120 or to combine the two, depending on which mode of operation is most suitable for current conditions. In this way, improved water extraction is enabled while the usability of the hybrid AWG system 100 across diverse climates is enhanced.

[0072] FIG. 3 is a schematic view of a control architecture 300 of the hybrid AWG system 100, according to an example. The control architecture 300 comprises a control system 310 comprising processing circuitry, configured to control a hybrid AWG system, such as the hybrid AWG system 100, and its mode of operation, as discussed in relation to FIG. 2. The control system 310 may correspond to the control system 170 described in relation to FIG. 1.

[0073] The control system 310 is configured to control operation of the hybrid AWG system 100 by acquiring input data relating to one or more parameters affecting operation of the cooling condensation circuit 110 and / or the desiccant circuit 120, determine control parameters 360 based on the acquired data, and control operation of the cooling condensation circuit 110 and / or the desiccant circuit 120 based on the respective determined control parameters 360. As discussed above, the control parameters 360 may include, for example, one or more of a position of the first and / or second air intake 130a, 130b (e.g. a percentage to which the respective intake is open), a cooling capacity of the condenser 140, an amount of heat provided by the heating device 150b (e.g. percentage activation of the heating device 150b), a speed and / or power of the at least one fan 160, a position of the valve 180 (e.g. a percentage to which the valve 180 is open), a percentage activation of a compressor cycle of the compressor 190b, and a percentage activation of a coolant flow in the compressor 190b

[0074] As discussed in relation to FIG. 1 , the control system 310 may be communicatively coupled to one or more systems configured to provide the input data to the control system 310. In one example, the control system 310 is coupled to a sensor system 330. The sensor system 330 is configured to acquire sensor data relating to one or more parameters affecting operation of the cooling condensation circuit 110 and / or the desiccant circuit 120. The sensor data may relate to parameters internal or external to the hybrid AWG system 100.

[0075] For example, external sensor data may relate to at least one of an ambient temperature, an ambient air humidity, and an atmospheric pressure. As discussedabove, these parameters will affect the ability of the cooling condensation circuit 110 and the desiccant circuit 120 to extract water from the ambient air, and may thus be used by the control system 310 to determine the degree to which each circuit should be operated.

[0076] Internal sensor data may relate to parameters of the air that has entered the hybrid AWG system 100 through at least one of the first and second air intake 130a, 130b. For example, internal sensor data may relate to at least one of a temperature, a humidity and a flow rate of the air inside the hybrid AWG system 100. Temperature data may be used by the control system 310 to determine appropriate (e.g. optimal) control parameters for the condenser 140 too cool the air to its dew point, or to determine appropriate (e.g. optimal) control parameters for the heating device 150b of the desiccant circuit 120. This ensures efficient water extraction while minimizing energy consumption. Air humidity data provide feedback on the moisture content of the air during different stages inside the hybrid AWG system 100, for example after desiccant absorption or before cooling. The humidity data thus helps the control system 310 to determine e.g. if adjustments to the desiccant regeneration or the cooling process are needed. Flow rate data provide information relating to the rate at which air moves through the hybrid AWG system 100. It allows the control system 310 to adjust e.g. operation of the at least one fan 160 or the degree to which the air intakes 130a, 130b and the valve 180 are opened, to achieve an air flow rate which ensures sufficient contact time between the air and the condenser or the desiccant, thereby optimizing moisture extraction while balancing energy use.

[0077] Internal sensor data may further relate to components of the hybrid AWG system 100. For example, internal sensor data may relate to at least one of a temperature of one or more components of the hybrid AWG system 100, a speed of the at least one fan 160, a water content of the desiccant 150a, a water flow rate inside the hybrid AWG system 100, and a current level of water in a tank of the hybrid AWG system 100. Temperature data enables the control system 310 to adjust heating or cooling processes as needed for increased water generation. Fan speed data allows the control system 310 to regulate the speed and volume of the airflow, to optimize the amount of air that is draw into to air intakes 130a, 130b, and the amount of time that the air is in contact with the desiccant 150a or condenser 140, thereby balancing water extraction rates with energy efficiency. The water content of the desiccant 150aenables the control system 310 to determine when regeneration is needed, and water level data helps the control system 310 manage the overall operation of the hybrid AWG system 100, such as interrupting water production when the tank is full.

[0078] In one example, the control system 310 is coupled to a monitoring system 340 configured to provide input data relating to internal performance metrics of the hybrid AWG system 100. For example, monitoring system 340 may provide data relating to at least one of a current and / or historic rate of water generation of the AWG system 100, a current and / or historic power usage of the hybrid AWG system 100 and a current and / or historic water demand from the hybrid AWG system 100.

[0079] This input data from the monitoring system 340 may be used by the control system 310 to balance supply and demand and optimize efficiency. For example, a rate of water generation may be monitored to adjust operation of the components of the hybrid AWG system 100 if the rate of water generation drops below a threshold. Power usage data may be used by the control system 310 to determine control parameters 360 which achieve a balance between power usage and water output. Water demand data may be used by the control system 310 to control operations such that water production aligns with consumption. For example, during periods of high demand, the control system 310 can prioritize processes that maximize water output, while during low demand it can conserve energy by reducing operation of certain components.

[0080] In one example, the control system 310 is coupled to an external system 350 configured to provide current and forecast weather data. This input data may be used by the control system 310 to optimize operation of the hybrid AWG system 100 based on current weather conditions as well as adapt to expected changes in weather. For example, the control system 310 may determine control parameters 360 based on current humidity levels, temperature levels and wind patterns, or adapt the control parameters 360 based on forecasted weather data. In this way, the control system 310 enables efficient operation of the hybrid AWG system 100 even under changing climatic conditions.

[0081] The control system 310 may use the input data provided by the sensor system 330, the monitoring system 340, and the external system 350 to generate a prediction of at least one of a future water demand, a future power usage, and future weather conditions, and to determine control parameters 360 based on the prediction.In this way, the control system 310 can determine which mode of operation to run based on at least one of a projected water demand, power usage and weather condition.

[0082] In one example, the control system 310 may be configured to determine the control parameters 360 based on an objective. The objective may be one or more of optimising water production, reducing cost of operation, and reducing energy consumption. In one example, the control parameters 360 further comprise a timeframe for operating the cooling condensation circuit 110 and / or the desiccant circuit 120 based on the objective. For example, if weather conditions are expected to become appropriate for operation of the desiccant circuit 120, the control system 310 may determine control parameters 360 to switch from a simultaneous operation of the cooling condensation circuit 110 and the desiccant circuit 120 to operating the desiccant circuit 120 only at a certain point in time. In the case that water demand is expected to be low while power usage is expected to be high for a duration of time, the control system 310 may determine control parameters 360 that cause the hybrid AWG system 100 to be put on standby until conditions for efficiently generating water improve.

[0083] The control parameters 360 may be continuously and / or periodically updated such that the control system 310 continuously determines the appropriate (e.g. optimal) operation of the hybrid AWG system 100 in order to both meet customer demands and to maximize energy efficiency in all weather conditions.

[0084] In some examples, the control system 310 is configured to determine control parameters 360 for the hybrid AWG system 100 using an artificial intelligence approach such as a machine learning algorithm 320. The machine learning algorithm 320 may be any known machine learning algorithm suitable for determining operational parameters based in input data. The machine learning algorithm may be trained, for example, on historical input data, such as environmental conditions, and corresponding outputs, such as water generation rates and energy consumption. During the training process, the machine learning algorithm learns to identify patterns and correlations in the training data. In this way, the machine learning algorithm 320 (or other artificial intelligence approaches) can identify patterns and relationships that influence the efficiency of the hybrid AWG system 100 and predict which control parameters 360 are appropriate for balancing water demand, energy usage and waterproduction efficiency. The machine learning algorithm 320 is employed by the control system 310 to process the various input data acquired from the sensor system 330, the monitoring system 340, and the external system 350. The machine learning algorithm 320 will continuously learns from new input data and create a model based on its current location, such that the system is enabled to adapt dynamically to varying conditions and demands.

[0085] The hybrid AWG system 100 of the embodiments described above takes advantage of the benefits provided by both cooling condensation technology and desiccant technology and allows water to be generated across a wide range of climatic conditions as well as during varying climatic conditions.

[0086] FIG.4 is a flow chart of a method 400 according to an example. The method 400 is for generating water from air using hybrid atmospheric water generation, AWG, system, such as the hybrid AWG system 100, wherein the hybrid AWG system 100 comprises a cooling condensation circuit 110 comprising a first air intake 130a and a condenser 140 configured to extract water from ambient air, a desiccant circuit 120 comprising a second air intake 130b and a desiccant 150a configured to absorb water from ambient air, and at least one fan 160 for causing the ambient air to enter the first air intake 130a and the second air intake 130b. The method may be implemented by processing circuitry of a control system, such as control system 170 described in relation to FIG. 1 or control system 310 described in relation to FIG. 3.

[0087] At 402 data relating to one or more parameters affecting operation of the cooling condensation circuit 110 and the desiccant circuit 120 is acquired. As discussed in relation to FIGs. 1 and 3, the control system may be communicatively coupled to one or more systems configured to provide the data to the control system.

[0088] In one example, the parameters comprise sensor data, for example relating to properties of the ambient air or the air inside the hybrid AWG system 100. In another example, the parameters comprise properties of the components of the hybrid AWG system 100, such as the temperature of one or more components. The parameters may also relate to internal performance metrics of the hybrid AWG system 100, for example a current and / or historic rate of water generation, a current and / or historic power usage and a current and / or historic water demand from the hybrid AWG system 100. In one example, the parameters relate to current and forecast weather data. In some examples, the method comprises predicting a future rate of water generation,power usage and water demand from the hybrid AWG system 100 as well as forecasting weather data, based on the acquired data.

[0089] By acquiring the various forms of input data relating to parameters affecting operation of the cooling condensation circuit 110 and the desiccant circuit 120, the method enables the hybrid AWG system 100 to be operated based on this data in subsequent steps of the method.

[0090] At 404, control parameters 360 for each of the cooling condensation circuit 110 and the desiccant circuit 120 are determined based on the acquired data. The control parameters 360 enable controlling a mode of operation of the hybrid AWG system 100, as discussed in relation to FIG. 2, by controlling the airflow into the hybrid AWG system 100 and operation of the various components.

[0091] In one example, the control parameters 360 are determined based on an objective, such as optimising water production, reducing cost of operation and reducing energy consumption. In one example, the control parameters 360 further comprise a timeframe for operating the cooling condensation circuit 110 and / or the desiccant circuit 120 based on the objective. The method may further comprise continuously and / or periodically updating the control parameters 360 in order to provide improved operation of the hybrid AWG system 100 based on the acquired data. In one example, the method comprises determining the control parameters 360 using an artificial intelligence approach such as a machine learning algorithm 320. In some examples, the method comprises determining the control parameters 360 to balance water demand, energy usage and water production efficiency.

[0092] At 406, operation of each of the cooling condensation circuit 110 and the desiccant circuit 120 is controlled based on the respective determined control parameters 360. For example, the hybrid AWG system 100 may be controlled to operate the cooling condensation circuit 110 only, the desiccant circuit 120 only, or both circuits simultaneously. The degree to which each circuit is operated may also be controlled, as discussed above.

[0093] The hybrid AWG system 100 and method 400 of the present disclosure enable water to be efficiently generated from humid air across a wide range of climatic conditions as well as during varying climatic conditions, by combining a cooling condensation circuit and a desiccant circuit into one system. In this way, the benefits provided by each circuit are taken advantage of and the hybrid AWG system is enabledto dynamically adapting to varying conditions and demands, such that a reliable and efficient water production is ensured.
