چکیده

امروزه به دلیل افزایش جمعیت، گسترش شهرها و کمبود منابع آب شیرین، کشف روش های جدید تولید آب از اهمیت بالایی برخوردار است. یکی از روش‌های نوین تولید آب شیرین در ظرفیت‌های پایین، استفاده از رطوبت هوا است که به عنوان سیستم تولید آب چگالشی شناخته می‌شود. در این تحقیق سیستم‌های تولید آب خوراکی با هدف به‌دست آوردن طول بهینه و ارزیابی پارامترهای موثر بر میزان آب تولید شده در سیستم‌های چگالشی مورد مطالعه و بررسی قرار گرفته‌اند. نتایج عددی نشان می‌دهند که در لوله‌ا‌ی به قطر 2/0 متر، در عمق نیم متری زمین و طول پانزده متر که دمای هوای ورودی 70 درجه سانتی‌گراد و رطوبت نسبی 70 درصد است، تقریبا 1/2 کیلوگرم آب در روز استحصال خواهد شد. آنالیز حساسیت بر روی پارامترهای مختلف و جنس خاک نیز انجام شده است. همچنین نتایج تحلیل نشان می‌دهد که دمای هوا و رطوبت نسبی بیش‌ترین تأثیر را بر میزان آب تولید شده دارند و به ترتیب ماسه، شن، خاک مرطوب و خاک رس بیشترین آب را تولید می‌کنند.

چکیده [English]

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.
