Abstract

Thermal-electrical circuit modeling is a well-established technique for the quantification of power dissipation in electronic devices and optimizing cooling means, but rarely used in building construction and facility energy management. In contrary to pure numerical simulations, equivalent circuit methods allow the derivation of useful formulas and rules of thumb. In most cases, modeling using electro-thermal analogy is limited to stationary considerations. The recent paper is understood as a short follow up of an earlier publication on the use of non-linear equivalent circuit techniques, extending the models by dynamic behavior and distributed parameters. We present refinements of the modeling framework. Also, the time and cost efficient use of commercially available electrical network simulation software is discussed.
