Thermoelectric Cooler Power Efficiency

Advantages of thermoelectric wine coolers.

Thermoelectric cooler power efficiency. 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. 5 100 hp 5 640 watts hp 15 efficiency of thermoelectric material 13 2 volts 181 amps available for. Because of the peltier effect these coolers have less moving parts which means they require less power than a compressor cooler would. 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.

For many years the main three semiconductors known to have both low thermal conductivity and high power factor were bismuth telluride bi 2 te 3 lead telluride pbte and silicon germanium sige. The efficiency of a given material to produce a thermoelectric power is governed by its figure of merit zt s 2 σt κ. Such an instrument is also called a. Thermoelectric wine coolers are more efficient at cool and use less electricity.

The principles of thermoelectric devices are reviewed and strategies for increasing the efficiency of novel materials are explored. If a unit was built to capture as much heat as possible say 50 of that. Tec controllers are used for thermoelectric cooling and heating in combination with peltier elements.
