It has been known for many years that reversible thermoelectric effects can be detected in a circuit consisting of junctions of two dissimilar materials having their junctions at different temperatures. The Peltier effect relates to the fact that heat must be exchanged by the junctions with the surroundings if the .unctions are maintained at different temperatures in the presence of a current flowing through the circuit. The amount of heat exchanged with surroundings changes with the change in the direction of the current. Because of this behavior, the junctions can be designed to add or to remove heat from the surrounding.
