Peltier effect

Physics

The change in temperature produced at a junction between two dissimilar metals or semiconductors when an electric current passes through the junction. The direction of the current determines whether the temperature rises or falls. The first metals to be investigated were bismuth and copper; if the current flows from bismuth to copper the temperature rises. If the current is reversed the temperature falls. The effect was discovered in 1834 by the French physicist Jean Charles Athanase Peltier (1785–1845) and has been used recently for small-scale refrigeration. Compare Seebeck effect.

Chemical Engineering

A thermoelectric cooling effect used in small-scale refrigeration units. It involves a solid-state heat pump that transfers heat from one side of the device to the other through the consumption of electricity. The thermoelectric cooling effect is created between the junction of two different types of conducting materials. The device can also be used for heating. It is named after French physicist Jean Charles Athanase Peltier (1785–1845) who discovered the effect in 1834.
