Modelling a thermoelectric heat exchanger

In this paper thermoelectric device models are developed using an experimental test rig and modeling methods based on least-square estimation. These devices are able to use electrical energy to cause thermal energy to flow faster than or against the normal thermal gradient. These devices are finding increased usage in industry, and also in more complex control-related tasks that require accurate models. While physical modeling is possible, in more complex configurations this can be difficult and alternate methods, such as system identification methods based on experimental data can be used more effectively.
