Thermoelectric Refrigeration System

A thermoelectric refrigerator, also known as a thermoelectric cooler module or Peltier cooler, is an electric component made of semi-conductors that acts as a tiny heat pump. When a thermoelectric cooler module is powered by a low voltage direct current power source, heat is transferred from one side to the other. As a result, one module face will be cooled while the opposite face is heated at the same time. The same fundamental laws of thermodynamics govern both thermoelectric and mechanical refrigerators, and both refrigeration systems, despite their vastly different appearances, operate on the same principles.
