Abstract

Nowadays, due to population growth, urban development and lack of fresh (drinking) water resources, the discovery of new ways of water production is of great importance. One of the new methods of producing the drinking (fresh) water at low capacities is the use of air humidity, which is known as condensed water production system. In the present research, drinking water production systems have been studied with the aim of obtaining the optimal length and evaluating the parameters affecting the amount of water produced in condensed systems. The obtained results show that 2.1 Kg water/day will be approximately extracted with considering D=0.2 m,y=0.5 m,L=15m,T_i=70 ℃,H_r=70 %. Sensitivity analysis has been also performed on various parameters and soil type. The obtained results of this analysis also show that air temperature and relative humidity have the greatest effect on the amount of produced water, and also sand, gravel, wet soil and clay produce the highest amount of water respectively. So, this research work may be beneficial and useful for human comfort and convenience. Finally, suitable and good results are obtained by the proposed method.
