Indus3es: test rig calibration and initial operation of an absorption heat transformer

Abstract

The absorption heat transformer is technology known for years, which heats water to high temperature from a heat supply at a medium temperature. This heat supply is usually waste heat coming from a chemical or petrochemical industry which, due to its low temperature, it is not useful any more. Around half of this waste energy can be recovered, so the installation obtains an amount of energy that, otherwise, would be thrown away. In the Indus3ES project (http://www.indus3es.eu/) , the very late developments in heat and mass transfer are used to develop a new absorption heat transformer, taking the absorption heat converter designed in the SEASE project as a reference. This thesis describes some of the di erent tasks performed during the assembly of the absorption heat transformer designed by the Institut für Energietechnik of the TU Berlin. With special focus on the installation and calibration of the measuring equipment, as well as an error propagation analysis which determines the precision of the measurements in the prototype, which shows the potential of improvement and di erent modi cations that may be interesting for the following projects performed in the department.
