Evaporative Cooling By Using Different Porous Materials
Abstract: The method of evaporative cooling involves raising the air temperature by causing water vapour in an airstream to evaporate. Waterneeds the latent heat of vaporisation to evaporate, and this heat is produced by ambient air and a drop in air temperature. A porousmedium is necessary for both direct and indirect evaporative cooling in order to allow heat and mass transfer between the medium'swater and the air moving through it, or …
