Abstract

The increasing demand for clean water and the diminishing supply of clean water sources can result in a clean water crisis. Air is a ubiquitous, inexpensive, and clean water source. Using Atmospheric Water Generators (AWG), the water contained in the air can be extracted. This study's objective was to determine the effect of inlet air temperature and air heater power variations on tool performance and PAWG condensate water production at a condenser angle of 75 degrees. The procedure utilized is experimental on three PAWG boxes. Each box has a distinct temperature at its entrance. The variation of inlet air temperature is accomplished by heating the air before it enters the box with an air heater; the applied power variations are 0.484 Watt, 0.964 Watt, and 1.702 Watt. The results demonstrated that variations in air heater power and inlet air temperature affected system performance and condensate water production. Maximum water discharge and PAWG performance were achieved when the air heating power was 0.48 watts and the water discharge was 1.166 milli liters per hour. At 0.0084 ml/h/W, the PSys system performance had the highest value. The variable air heating power of 0.946 Watt represents the utmost COP value of PAWG. This power variable has a high temperature difference and influences the COP value at high levels.

Abstract

Passive solar desalination is a process of reducing the salt content of salt water to produce fresh water by utilizing solar heat. In recent years, interfacial heating has been proposed as an alternative to evaporation by creating localized heat on the water surface. Charcoal is an absorbent, heat storage, and wettability material, so the evaporation process not only occurs on the surface of seawater but also on the surface of the charcoal, which results from this wettability. The height of the charcoal indicates the distance the steam travels to reach the glass surface for the condensation process, thereby speeding up evaporation. The experiment was carried out in 4 single-slope-type basins using tubes filled with charcoal as high as 30, 40, and 50 mm for 8 hours in the sun. The results showed that adding heat-absorbing material to the basin was able to accelerate seawater to reach its boiling point so that it could evaporate. The temperature and humidity in each basin also have a similar changing trend where temperature is strongly influenced by solar radiation. The use of charcoal can also increase the rate of convection and evaporation heat transfer in the basin, as well as the maximum efficiency in basin 4 with an efficiency value of 56.40%, basin 2 at 53.17%, basin 3 at 51.62%, and basin 1 44.17%. Efficiency is obtained from the desalination efficiency equation, namely the ratio of the latent heat of vaporization to the solar energy entering the system
