Air Purification And Cooling System Using Titanium Dioxide Nanofluid: A Review

Abstract

By passing the outside polluted air through the honeycomb filter via titanium dioxide nanofluid as well as using the heat transfer properties of titanium dioxide for cooling of this filtered air. The ultraviolet (UV) rays serving as the exciter for the photocatalytic effect which helps the Titanium oxide for the reduction of air pollutants and enhancing the air quality. Atmospheric deposition of pollutants is a major challenge for the environmental governance and management of different depositions could be harmful especially in the air. The main objective is to illustrate the latest achievements in terms of the use of titanium dioxide to neutralize pollutants like NOx, SOx, CO, specks of dust, and aromatic substances. The various concentration of titanium dioxide in the water is checked to see best suitable concentration ranging from 3% to 5% weight concentrations and the particle size of nanometer based on availability and cost, which will range from 40nm to 50 nm. By experimenting with various concentrations of Titanium dioxide in water achieves different results depending upon the external environment. Hence using polluted air as input achieves filtered, clean as well as cooled air.
