Análise quantitativa da vazão da água condensada em aparelhos condicionadores de ar para fins não potáveis

Abstract

The population increase responsible for the growing demand for drinking water, linked to pollution and the irrational use of water, results in a scenario in which water scarcity is present globally, especially in regions with low precipitation and dry climate. Seeking to reduce the consumption of drinking water for less noble uses, to reduce the pressure under the water reservoirs, and to combat the water scarcity, the concept of rational use of water arises. Based on the principles of minimization, separation and reuse, this concept brings with it the suggestion of the use of alternative sources of water, one of them is the condensed water coming from air conditioners. The operation of air conditioners causes water condensation, and this effluent, mostly, is neglected. The present work was realized out with the objective of investigating and analyzing the factors that influence the flow of water generated by condensation in the air conditioners. Bibliographical and documentary researches were realized out, the volumes generated by the equipaments were collected, and the quantitative analysis of the flow of the condensed water was done. The results showed significant flow rates ranging from 0,6 to 5,14 l/s in single devices, it is possible to delineate a mathematical model to estimate the flow of this alternative water source, which allows the feasibility analysis of its use for non potable purposes, such as the washing of the floor, flushing and irrigation.
