Karl Petzold (thermodynamics)

from Wikipedia, the free encyclopedia

Karl Petzold (born April 27, 1926 in Zwickau - Planitz ; † March 14, 2006 in Dresden ) was a German thermodynamicist , university professor and founder of the scientific field of building climatology .

Life

Karl Petzold completed his schooling in 1946 (interrupted by the use of flak helpers and a serious war injury from 1943 to 1945) with the Abitur. He studied mechanical engineering in Dresden, his professional career led him via Agfa Wolfen to the Institute for Air and Refrigeration Technology in Dresden. There he did his doctorate and wrote his publication "On the development and future tasks of air conditioning technology".

The TU Dresden appointed him in 1968 to succeed Professor Arpad Kussmann (1902–1996), the head of the Institute for Technical Building Hygiene and Building Services . In the almost 25 years that followed, he published over 200 articles, mainly in the magazine “Luft und Kältetechnik” from the institute of the same name, supervised forty doctoral students and several projects for industry.

Petzold founded the research and teaching area of ​​building climatology, which he headed as institute director at the Technical University of Dresden from 1972 to 1992. It solved numerous building climate problems and their practical calculation. The focus of his work was the transport of energy and materials in buildings. He pursued the goal of climate-friendly building, including hygienic and economic constraints, with a focus on free air conditioning , especially in the "summer", as well as energy-economical problems, heating energy requirements, economically and energetically optimal thermal protection, as well as the ventilation-related coupling of external components.

Petzold already included the gray energies in his optimization process.
