Energy consumption all over the world is increasing rapidly and there is pressing need to develop ways to conserve energy for future generation. The conventional refrigeration system consumes very large amount of power (about 1.5 KW). Also for cooling, Evaporative coolers are the better option. The cost of Evaporative coolers is low and also it consumes less power than that of AC. The main drawback of Evaporative cooler is that the air supplies by it has very large amount of Humidity. Due to which when an individual sits in the air of evaporative coolers, he fills stickiness on his body which is not comfortable condition. So this project work involves the design and manufacturing of the “evaporation cooling air cooler cooling with dehumidification and heating” which will not increase the humidity of air. It will maintain the room at comfort conditions by using the silica gel to reduce the humidity of air. This cooler will work in both the season winter and summer. In winter season, cooling module is stop and heating module is on, so that air is heated by heater and it will ultimately increase the temperature of air. In summer season, cooling module is on and heating module is off, it will ultimately decrease the temperature of air up to 10°C. In summer season silica gel is also be used to reduce the humidity of air. After manufacturing this air cooler efficiency is measured by various performance measuring devices and instruments. Here thermometer and hygrometer are used to measure the temperature of air and humidity of air.
