Air-conditioning based on Peltier Effect

Wasif Qamar

An attempt has been made to develop an air conditioning system based on the thermoelectric effect which can work on a smaller scale more efficiently than the existing systems based on the same principle (The Peltier Effect). It has got an effective new concept for the desired effect. In this system, heat is extracted from one side of a Peltier module generally termed as the cold side of the same and the extracted heat is supplied to another side of the Peltier module (Cold Side) under the action of the Peltier effect. The cold side so formed is used to cool the water so that the water can absorb heat when circulated through the copper tube winding placed in front of the main fan, this ultimately enables the main fan to deliver cold air. Similarly, by reversing the polarity of the current being provided to the Peltier module one can convert the cold side of the module to the hot side and vice-versa, in this way one can get cold and hot air as per the requirement.
