Thermoelectric Cooler Power Efficiency

Because of the peltier effect these coolers have less moving parts which means they require less power than a compressor cooler would. A peltier cooler heater or thermoelectric heat pump is a solid state active heat pump which transfers heat from one side of the device to the other with consumption of electrical energy depending on the direction of the current. The efficiency of a peltier element application depends on the coefficient of performance cop which depends on the operating point the thermal design and the tec controller supply type.
