Abstract

Air conditioning has become a vital part of our day to day lives, but with the current cooling solutions there are concerns regarding to high energy consumption and emission of dangerous gases depleting the ozone layer. An evaporative cooling system (ECS) is considered as one of the oldest and low-cost cooling systems. However, the temperature drop in ECS is low and hence in this work, a three-stage cooling system was developed and tested for its performance.

This system consists of indirect and direct evaporative cooling system.  The combination of indirect and direct ECS reduces the dry bulb temperature significantly.  The experimental results show that the temperature drop in two stage is higher than the single stage. It is also observed that the energy consumed by this system is low as compared to conventionally used HVAC system. From this work, we conclude that the multistage evaporative cooling system can be used as an alternative to the HVAC system for commercial and industrial applications.
