Using the Hardware-in-the-Loop concept for energetic evaluation of heat generators

Abstract

Currently available energetic evaluation methods for heat pump and micro-CHP systems lead to results which partly deviate strongly from field measurements. A new evaluation method based on the Hardware-in-the-Loop concept was therefore developed and tested in a research project. The method employs representative days. A procedure for determining the representative days is presented. The functionality of the concept could be proven in a round robin test and the energetic key figures can be confirmed by values from field measurements values.
