WATER USE FROM THE CONDENSATION PROCESS OF AIR CONDITIONING APPLIANCES IN A PUBLIC BUILDING

Abstract

In the twentieth century it was common to have reports in the technical literature that water was a finite good. However, the reality is that in several states, water supply is threatened by both quantity and quality problems. The use of water from the condensation process of air conditioners can reduce the use of drinking water for less noble purposes. The present paper has the objective of evaluating the use of water from the air conditioning drains in the Center of Management of Physical Space of the Federal University of Goiás for non potable purposes. It was evaluated split air conditioning of 12,000 and 60,000 BTUs in the dry and rainy seasons in the years of 2015 and 2016. In the physico-chemical analyzes of the samples the parameters were evaluated: total alkalinity, carbonate, hydroxide, alkalinity, chlorides, carbon dioxide , copper, conductivity, hardness, sulfur, iron, taste and odor, apparent color, consumed oxygen, pH, dissolved solids and turbidity as recommended by the Standart Methods for Examination of Water and Wastewater of the America Water Works Association and the and the Environmental Sanitation Technology Company of São Paulo. The volume of water produced in the dry and rainy seasons was 1,591 and 2,713.96 l / month, respectively. The monthly financial savings are still small, and the result of the laboratory analysis of the physical-chemical parameters made it impossible to use them for drinking purposes.
