EFFECT OF THERMOELECTRIC MODULE ON AIR TEMPERATURE: A EXPERIMENTAL STUDY

A thermoelectric (TE) module, also called a thermoelectric cooler or Peltier cooler, is a semiconductor-based electronic component that functions as a small heat pump. By applying a low voltage DC power to a TE module, heat will be moved through the module from one side to the other. One module face, therefore, will be cooled while the opposite face is simultaneously heated. It is important to note that this phenomenon may be reversed whereby a change in the polarity (plus and minus) of the applied DC voltage will cause heat to be moved in the opposite direction. Consequently, a thermoelectric module maybe used for both heating and cooling thereby making it highly suitable for precise temperature control applications. A thermoelectric module can also be used for power generation. In this mode, a temperature differential applied across the module will generate a current. The intake is heated using thermo electric module. Its purpose is to heat the air at most by using less energy. Different arrangements of modules will be made to check the effect at different positions. The inlet conditions like velocity and temperatures are measured and so the outlet. In this work it is proposed to analyze the effect of air velocity on temperature profile. The temperature is measured using thermocouple. A thermoelectric device for measuring temperature, consisting of two wires of different metals connected at two points, a voltage being developed between the two junctions in proportion to the temperature difference
