Design and Development of Portable air cooler

In convention Air cooler, the outside air comes in contact with the water on the cooling pads. This outside air gives latent heat of vaporization to the water. Due to this water evaporates and that vapor get mix with the air the humidity of air has been increased. This increase in the humidity reduces the Human comfort, the chances of bacteria, viruses have been increased sandal so this condition is not suitable human comfort and to asthmas patient. So, we modified an Air Cooler, which will not increase the percentage of humidity in the air. The aim of this project is to develop portable Air Cooler which will not increase the humidity of the air as in case of Conventional Air Cooler. Air Cooler is an appliance that keeping the atmosphere cold. The basic concept is to make the indirect contact of water and air which goes out of the cooler for giving comfort. This project is to design and develop a low-cost portable air cooler as compared to Air conditioning system which can be used in Cars trucks and vehicles without A/C, house and office. Key Words: Indirect evaporative cooling, portable air cooler, fan
