“…The experimental data were extracted from reference (Suryaningsih & Nurhilal, 2016) where and atmospheric water generator (AWG) was used for freshwater recovery directly from the moisture content of water vapor from the air. It appears from the results depicted in Figure 18 that the model and experimental data obtained after reference (Suryaningsih & Nurhilal, 2016) are in fair agreement. However, some discrepancies exit between the model prediction and experimental data This could be ascribed to the different assumptions and relationships used in the model to calculate the water productivity.…”

Solar energy has many useful applications, particularly, for generation of electricity for rural areas. Solar energy has significant advantages including environmentally friendly, noise and pollution free, also considered as renewable energy and maintenance is not an issue in remote areas (Abdullahi et al., 2017). This reference also reported that the solar radiation is affected by both mean air temperature and relative humidity. Suryaningsih and Nurhilal (2016) developed an Atmospheric Water Generator (AWG) prototype based on Thermo-electric cooler (TEC) suitable renewable energy resource. Computational Fluid Dynamics (CFD) was utilized to optimize the design process Some parameters such as temperature, moisture content, air flow, pressure,

“…Atmospheric water generation has become increasingly popular in the developing world where potable water is scarce and electricity production is limited [1][2][3][4][5][6]. In these climates, Thermoelectric Coolers (TECs) are commonly used as they provide a feasible and sustainable solution to the growing demands of the inhabitants [3][4][5][7][8][9]. In response to the dwindling of fresh water supplies due to climate change, many countries are researching alternate solutions for potable water production.…”

Water is, arguably, Earth's most valuable and vital resource. Devices that extract water from the atmosphere have been intensely researched as a means of harvesting potable water in environments where it is otherwise scarce. One such device is a Thermoelectric Cooler (TEC); a device that utilises the Peltier effect to cool a system. TECs are a promising solution for atmospheric water generation (AWG) over their competitors due to their simplicity and refrigeration capabilities. Despite these advantages, TECs are still considered mostly inefficient as they demand relatively high costs and energy consumption. This meta-analysis focuses on optimising the efficiency of small-scale Peltier devices. It explores the means of optimising the liquid cooled heat sink by using a specific flow field microchannel configuration such that less pumping power is required to push the coolant and more energy can be saved. A combination of optimal operating current of the Peltier device and of a novel flow liquid-cooled microchannel heatsink configuration with bifurcated fins using Galinstan as a coolant promises a significant increase in water production per unit of energy consumption for the AWG system.

Found in some specific scenarios, drinking water is hard for people to get, such as during expeditions and scientific investigations. First, a novel water generator with only two thermoelectric coolers (Model A) is designed for extracting water from atmospheric vapor and then experimentally studied under a small inlet air flow rate. The impact of operating conditions on surface temperatures of cold/hot sides and water yield are investigated, including the air flow rate and humidity. Alternately, to determine the super performance of Model A, a comparative experiment between Model A and a reference model (Model B) is carried out. The results suggest that both the cold/hot temperature and water yield in Model A increases with the humidity and air flow rate rising. Seen in comparisons of Model A and Model B, it is found that, at an air humidity of 90% and air flow rate of 30 m3/h, the total water yield was increased by 43.4% and the corresponding value reached the maximum increment of 66.7% at an air humidity of 60% and air flow rate of 30 m3/h. These features demonstrate the advantage of Model A especially in low air humidity compared to Model B.
