Thermoelectric refrigeration is a thermoelectric-based refrigeration method. Two different metal wires (two conductors are a P-type semiconductor and an N-type semiconductor respectively) are connected with each other to form a closed circuit, and when the two connection points are placed at two positions with different temperatures respectively, a potential difference, namely contact electromotive force, is generated between the two connection points. While a current flows in the closed circuit. Conversely, a closed circuit formed by connecting two different wires to each other is energized with direct current, which results in two connection points of different temperatures. When direct current is applied, one of the connection points is heated and the other connection point is cooled. This is the peltier effect, also known as the thermoelectric phenomenon. The production cold end is the refrigeration space we need.
