Abstract
Every year electricity gets more and more expensive. The electric energy is produced by different sources like hydroelectric power plants, thermal energy power plants, nuclear power plants, etc. The application uses the electric energy and does the work. All the work done is not utilized, some of work gets wasted. So the ways to avoid the wastage must be found out. There are different ways to recover from the energy crisis.
In a water cooler, water is cooled with the help of electric energy. Most of the time the cold water gets wasted in varying amounts. So indirectly the electric energy gets wasted. This energy must be saved.
This project deals with designing and developing a working model of heat exchanger. A heat exchanger is a piece of equipment built for efficient heat transfer from one medium to another with or without direct contact between the working fluids. This heat exchanger is used to minimize the energy consumption of water coolers. Main objective of the project is pre-cooling of filtered water by using drain water as a cooling medium. This heat exchanger is fitted externally to the water cooler without changing any internal setup of the water cooler. Thus without use of any external work this Heat Exchanger works successfully and required results are obtained.
