Numerical examination of water production by underground condensation system

Water production by underground condensation is a low-capacity water-gathering technology for hot, humid climates. Hot, humid air is routed to subterranean pipes where it is progressively cooled and the vapor within the pipes appears as water droplets on the pipe surface. The goal of this paper is to quantify the amount of water extracted in the condensation system of humid and hot air. The water produced from humid air in buried pipes in the ground at a 0.5 m depth with different lengths is evaluated using MATLAB software, and optimal pipe length is established. Numerical findings show that water production is about 1 kilogram per day. It has been investigated how air temperature, pipe material, soil temperature, air humidity, and input speed influence underground condensation water production. It has been determined that 20 meters is the optimal length of the pipe. According to studies, Sandstone soil can produce 86%more water than other types of soil. It is also revealed that copper pipes could improve efficiency by 31%. The impact of effective factors on the efficiency of the condensation system, such as intake air temperature and humidity, inlet air velocity, and soil temperature, has also been assessed.
