Thermal modelling and performance evaluation of a low-grade heat-driven sorption-based atmospheric water generator under various weather conditions
Abstract Drinking water is scarce in many regions of the world despite the omnipresence of water in the form of vapour in large quantities in the atmosphere. Currently, majority of water harvesters use vapour compression refrigeration cycle, which is inefficient. Thus, to reduce electrical energy co...

| 520 | |a Abstract Drinking water is scarce in many regions of the world despite the omnipresence of water in the form of vapour in large quantities in the atmosphere. Currently, majority of water harvesters use vapour compression refrigeration cycle, which is inefficient. Thus, to reduce electrical energy consumption, the idea proposed in this study is to use a sorption-based atmospheric water generator (AWG) which works on low-grade heat energy. The key component of the proposed AWG is a desiccant-coated fin tube heat exchanger (DCFTHX) which humidifies and heats the air to such an extent that the vapour present in the air can be condensed by simply bringing it in thermal contact with a surface at atmospheric temperature. Thermodynamic modelling of the proposed AWG is first presented, followed by a systematic study under various weather conditions ranging from temperatures of 6 °C to 40 °C and specific humidity from 0.004 to 0.22 kg kg d.a.−1. Results indicate that water can be produced even for specific humidity of 4 kg kg d.a.−1 (near zero dew point temperature) if the ambient temperature is low (10 °C), at regeneration temperatures of 60 and 70 °C. The highest rate of water extraction and the highest yield is 10.9 g $ s^{−1} $ and 62.2 kg $ kWh^{−1} $, respectively, under ambient conditions of 26 °C and 0.02 kg kg d.a.−1. Under the winter (when the absolute humidity is at its lowest) weather conditions of Dubai, as much as 39.3 kg of water can be produced per kWh, which translates to only 0.59 cents per kg water produced. | ||

Abstract Drinking water is scarce in many regions of the world despite the omnipresence of water in the form of vapour in large quantities in the atmosphere. Currently, majority of water harvesters use vapour compression refrigeration cycle, which is inefficient. Thus, to reduce electrical energy consumption, the idea proposed in this study is to use a sorption-based atmospheric water generator (AWG) which works on low-grade heat energy. The key component of the proposed AWG is a desiccant-coated fin tube heat exchanger (DCFTHX) which humidifies and heats the air to such an extent that the vapour present in the air can be condensed by simply bringing it in thermal contact with a surface at atmospheric temperature. Thermodynamic modelling of the proposed AWG is first presented, followed by a systematic study under various weather conditions ranging from temperatures of 6 °C to 40 °C and specific humidity from 0.004 to 0.22 kg kg d.a.−1. Results indicate that water can be produced even for specific humidity of 4 kg kg d.a.−1 (near zero dew point temperature) if the ambient temperature is low (10 °C), at regeneration temperatures of 60 and 70 °C. The highest rate of water extraction and the highest yield is 10.9 g $ s^{−1} $ and 62.2 kg $ kWh^{−1} $, respectively, under ambient conditions of 26 °C and 0.02 kg kg d.a.−1.

Currently, majority of water harvesters use vapour compression refrigeration cycle, which is inefficient. Thus, to reduce electrical energy consumption, the idea proposed in this study is to use a sorption-based atmospheric water generator (AWG) which works on low-grade heat energy. The key component of the proposed AWG is a desiccant-coated fin tube heat exchanger (DCFTHX) which humidifies and heats the air to such an extent that the vapour present in the air can be condensed by simply bringing it in thermal contact with a surface at atmospheric temperature. Thermodynamic modelling of the proposed AWG is first presented, followed by a systematic study under various weather conditions ranging from temperatures of 6 °C to 40 °C and specific humidity from 0.004 to 0.22 kg kg d.a.−1. Results indicate that water can be produced even for specific humidity of 4 kg kg d.a.−1 (near zero dew point temperature) if the ambient temperature is low (10 °C), at regeneration temperatures of 60 and 70 °C. The highest rate of water extraction and the highest yield is 10.9 g $ s^{−1} $ and 62.2 kg $ kWh^{−1} $, respectively, under ambient conditions of 26 °C and 0.02 kg kg d.a.−1. Under the winter (when the absolute humidity is at its lowest) weather conditions of Dubai, as much as 39.3 kg of water can be produced per kWh, which translates to only 0.59 cents per kg water produced.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Atmospheric water generator</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Atmospheric water harvester</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Desiccant-coated heat exchanger</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Thermal modelling</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Internally cooled and heated fin tube heat exchanger</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Punnoose, Emma Mariam</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jagirdar, Mrinal K.</subfield><subfield code="e">verfasserin</subfield><subfield code="0">(orcid)0000-0002-6393-5781</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of thermal analysis and calorimetry</subfield><subfield code="d">Springer International Publishing, 1969</subfield><subfield code="g">149(2024), 13 vom: 15.

Thermal modelling and performance evaluation of a low-grade heat-driven sorption-based atmospheric water generator under various weather conditions |
| abstract |
Abstract Drinking water is scarce in many regions of the world despite the omnipresence of water in the form of vapour in large quantities in the atmosphere. Currently, majority of water harvesters use vapour compression refrigeration cycle, which is inefficient. Thus, to reduce electrical energy consumption, the idea proposed in this study is to use a sorption-based atmospheric water generator (AWG) which works on low-grade heat energy. The key component of the proposed AWG is a desiccant-coated fin tube heat exchanger (DCFTHX) which humidifies and heats the air to such an extent that the vapour present in the air can be condensed by simply bringing it in thermal contact with a surface at atmospheric temperature. Thermodynamic modelling of the proposed AWG is first presented, followed by a systematic study under various weather conditions ranging from temperatures of 6 °C to 40 °C and specific humidity from 0.004 to 0.22 kg kg d.a.−1. Results indicate that water can be produced even for specific humidity of 4 kg kg d.a.−1 (near zero dew point temperature) if the ambient temperature is low (10 °C), at regeneration temperatures of 60 and 70 °C. The highest rate of water extraction and the highest yield is 10.9 g $ s^{−1} $ and 62.2 kg $ kWh^{−1} $, respectively, under ambient conditions of 26 °C and 0.02 kg kg d.a.−1. Under the winter (when the absolute humidity is at its lowest) weather conditions of Dubai, as much as 39.3 kg of water can be produced per kWh, which translates to only 0.59 cents per kg water produced. © Akadémiai Kiadó, Budapest, Hungary 2024.

Under the winter (when the absolute humidity is at its lowest) weather conditions of Dubai, as much as 39.3 kg of water can be produced per kWh, which translates to only 0.59 cents per kg water produced.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Atmospheric water generator</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Atmospheric water harvester</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Desiccant-coated heat exchanger</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Thermal modelling</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Internally cooled and heated fin tube heat exchanger</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Punnoose, Emma Mariam</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jagirdar, Mrinal K.</subfield><subfield code="e">verfasserin</subfield><subfield code="0">(orcid)0000-0002-6393-5781</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of thermal analysis and calorimetry</subfield><subfield code="d">Springer International Publishing, 1969</subfield><subfield code="g">149(2024), 13 vom: 15.
