Dr.-Ing. Sebastian Herrmann, from the Technical Thermodynamics Division in the Faculty of Mechanical Engineering, presented a lecture at the conference of the "American Society of Heating, Refrigerating, and Air-Conditioning Engineers” (ASHRAE) in Chicago (USA), presented the results of the research project he led in the field of the transport properties—viscosity and thermal conductivity—of humid air.
In addition to the project leader, Prof. Dr.-Ing. habil. Hans-Joachim Kretzschmar—also from the Technical Thermodynamics Division—scientists from the University of Rostock and the University of Maryland (USA), as well as an ASHRAE expert in the field of humid air. Among other things, the algorithms developed in the project were used to recalculate tables and diagrams for the next edition of the “ASHRAE Handbook of Fundamentals,” the standard reference work for calculations in the fields of heating, refrigeration, and air conditioning. This project is already the second research project conducted by the Technical Thermodynamics Department on behalf of ASHRAE.
Another important aspect of the conference participation was the collaboration of Prof. Kretzschmar and Dr. Herrmann on a current research project aimed at developing a new ASHRAE standard for calculating the thermodynamic properties of humid air.
Furthermore, at the ASHRAE Winter Conference in Chicago, Prof. Kretzschmar and Dr. Herrmann presented software for calculating the thermodynamic and transport properties of humid air, which was developed at Zittau/Görlitz University of Applied Sciences.
Following the conference, further details of the joint research projects were discussed with experts from the University of Maryland and ASHRAE.
