Abstract

This paper presents the performance analysis of a new evaporative cooling pad material ''Luffa'', or luffa, sponges which are produced from long, thin gourds and are much harder and more abrasive than sea sponges. Most often, luffa sponges are used for scrubbing and exfoliating dead skin. Often seen for sale in stores in the form of back brushes exfoliating mitts, luffa sponges also make ideal scrubbers for pots, pans and surfaces, such as the counter tops. The luffa sponges is an amazing versatile, no-fuss plant that is relatively easy to grow in warm climates [1]. A test tunnel is constructed for this particular work and the behavior of this new evaporative cooling pad material is analyzed while changing of three parameters. Air velocity, water flow rate and the bad thickness. Inlet and outlet air characteristics are recorded with time and transit variation of thermo-physical properties of air is then evaluated from the measured data and heat and mass transfer equations. Cooling effectiveness, heat transfer coefficient, mass transfer coefficient and accordingly Nusslet and sSherwod numbers are obtained and compared each time. This new bad materials offers the lowest pressure drop among other materials (<10N/m2) with high effectiveness(94%). Because of better performance, lower costs and easy availability of this new bad material. Using it as wetted media may enhance the scope of using this material in domestic and commerical evaporative cooling systems for sustainable development.
