A Multi Stage Study of Thermoelectric Device Based on Semi-conductor Materials
The present work dedicated to the study and analysis of a multi stage study of thermoelectric cooler based on hydrogen liquefier. For this purpose, the Seebeck and Peltier effect are used for simulate thermoelectric cooler. The energy equation has been used under the following conditions for prediction the efficiency of hydrogen liquefier. The properties of semi-conductor materials corresponding of cryogenics process were defined. A multi stage process has been proposed for decrease cold temperature of cold exchanger. The obtained results, including power and coefficient of performance are presented and discussed.
