Abstarct: In recent decades many scientific works have been carried out to accomplish new solutions to improve and achieve new resources. One of these new resources is the water vapor content of moist air. The objective of this study is to analyze retrieval and extracting liquid water from atmospheric water vapor as a new source of fresh water. A comparison of this method with desalination is carried out, too. Different ways are known to extract liquid water from vapor. Cool surface is one of the simplest methods making it feasible to implement the whole system not only in coastal area but also in arid zones.
In recent studies fresh water production mostly has been considered as by-product of air conditioning processes or analyzed by weather condition taken into account only. In this work a gas compression refrigeration cycle is designed and the results of its performance are analyzed with the approach of product amount and energy intensity in different climate conditions. Despite of many previous studies it has been tried to provide more real working conditions and many simplifier assumptions has been avoided. A case study is carried out baxse on the climate that fits ambient temperature and humidity intervals of systems best performance. The results show that a residential size of this system can produce average amount of fresh water. Economic analysis shows that this system can compete with current desalination methods. Although energy intensity is high, having considerable environmental advantages this system can play an important role in future of fresh water supply demanded by societies suffering from water scarcity.
