Peltier cooler efficiency calculation.

In this episode we discuss peltier coefficient of performance efficiency this video series was made in response to the many youtube tec peltier efficiency. 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. Peltier thermoelectric cooler module calculator calculate the thermoelectric peltier cooling module that is best for your application. Tetechnology designs and manufactures the highest quality thermoelectric coolers cold plates liquid coolers and thermoelectric coolers.

For comparison purposes a typical thermoelectric peltier cooler has a carnot efficiency of about 5 8. 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. 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. Thus the 5 6 amp 8 2 volt cooler is selected because between these two potential tecs its qmax 30 watts is closest to the optimum qmax 36 watts.

Lead wire external metalization options. Such an instrument is also called a. For this example let us assume maximum efficiency is desired. Tec controllers are used for thermoelectric cooling and heating in combination with peltier elements.

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. If i tec increases from 0 62 a to 0 8 a the heatsink will warm up by approximately 8 c and overwhelm the effect of additional peltier heat transport. 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.

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. The effect is even stronger in circuits containing dissimilar semiconductors.
