Peltier Cooler Efficiency Calculation

Tetechnology designs and manufactures the highest quality thermoelectric coolers cold plates liquid coolers and thermoelectric coolers.

Peltier cooler efficiency calculation. For this example let us assume maximum efficiency is desired. Peltier thermoelectric cooler module calculator calculate the thermoelectric peltier cooling module that is best for your application. 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. Thermoelectric cooling uses the peltier effect to create a heat flux at the junction of two different types of materials.

Peltier effect the cooling of one junction and the heating of the other when electric current is maintained in a circuit of material consisting of two dissimilar conductors. Such an instrument is also called a. Lead wire external metalization options. Tec controllers are used for thermoelectric cooling and heating in combination with peltier elements.

When the second law of thermodynamics states that not all the energy supplied to a cooler can be used to cool the carnot efficiency sets the limiting value on the fraction of the energy which can be so used. Iso 9001 certified. Consequently t1 will move in the wrong. For comparison purposes a typical thermoelectric peltier cooler has a carnot efficiency of about 5 8.

In a circuit consisting of a battery joined by two pieces of copper wire to a length of bismuth wire a temperature rise occurs at the junction. Video peltier module cooling the peltier effect the following video shows taking the peltier module from the above water dispenser and doing this peltier cooling efficiency test. It has the additonal feature of showing a little water being turned to ice while sitting on the peltier module for just a few minutes. All three points are discussed in this article.

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. In this episode we discuss peltier coefficient of performance efficiency this video series was made in response to the many youtube tec peltier efficiency.
