Paper Title
Performance Evaluation of Porous Clay-Tube Air Cooler in Comparison with Conventional Evaporative Air Cooling System
  Kkailash Patidar,  Kapil Nahar

Now a day due to energy crisis and increasing demand along with its harmful effect to environment, there is urgent need of energy saving in air cooling systems. Although, evaporative cooling is well known technique from long time providing best results with applicability in number of areas such as, in residential, commercial, agricultural, and institutional buildings to industrial applications. However, Direct evaporation systems lead to increased humidity causing a number of ailments like whereas indirect systems suffer from loss in efficiency. Keeping these points in view, this paper describes the development of a test setup and performance evaluation of a clay tube air cooler. This system may also be used as an enthalpy exchanger depending upon the characteristics of prevailing air. Water in the tank is made to drip at a controlled rate into the porous clay pipes that allow capillary action. A thin layer of water formed on the surface of clay pipes is used to exchange sensible and latent heat with the current of outdoor air. The water circulating pump which is a primary component of any evaporating cooling system is absolutely not required in this system. This system is highly efficient can save up to 30-40% of high-grade electrical energy and 50% of the water in comparison to conventional evaporative air cooler. This paper covers performance evaluation of the system in terms three response parameters i.e. Dry bulb temperature (DBT), Wet bulb temperature (WBT) and Relative Humidity (RH).

Keywords- Evaporative system, clay pipes, DBT, WBT, RH.
