CFD ANALYSIS OF A DE-HUMIDIFIER UNIT

Drinking water is vital and in ever increasing demand. The desire for hygienic water is an incentive to produce and maintain it at the desired level for domestic use. Drinking water, in addition to providing the body with the water it needs, contains minerals and essential elements for the body, the lack of some of which can sometimes cause various diseases, for example, fluoride deficiency. In addition to various chemicals, various microorganisms are also found in water, some of which are pathogenic and cause many losses if not treated properly (Mohammadi, A, ۲۰۱۲). Based on the results of experiments on water in the air (air humidity) compared to other methods, it’s quality is physically odorless and its pH is within the threshold. It should be noted that due to the lack of some elements, it almost has a very low hardness, which is compensated by adding the required elements (Bahrami, S et al, ۲۰۱۵) . Therefore, it can be concluded that water in the air is one of the most suitable types of water for human use. The important issue here is the existence of abundant natural water reservoirs in the form of water vapor in the world. In the hydrological cycle, all water vapor from solar energy radiation is not converted into precipitation (atmospheric precipitation), but part of the water vapor is not converted into precipitation due to low density and is scattered in space visible or invisible. The important question now is how to put this potential force into action. In recent years, scientists have been able to collect fog and high humidity and convert them to fresh water using simple physical laws (Bazargan, M et al, ۲۰۱۴)
