Design and Testing of Cooling Jacket using Peltier Plate

With the increasing rate of air pollution in whole world, the duration of summer season is increasing day by day and with the passage of time the daytime temperature is also increasing. Now it is becoming very difficult to work under the sunlight in hot summer days therefore, we proposed an idea of a cooling jacket which consists of peltier plate along with heat sinks and small DC fans, whenever current passes through the Peltier plate it produces cooling and fan circulates the cold air inside the jacket. Solar strip is attached on the upper layer of jacket to power up the system and the peltier current control circuitry is controlled using lilypad arduino. The goal is achieved successfully, maintaining the inside temperature of jacket within the range of 25-30°C with outside temperature around 35-45°C.
