Harry Rosin

from Wikipedia, the free encyclopedia

Harry Rosin (* 1943 ) is a German medic. As a senior researcher at the Institute of Hygiene Dortmund he developed together with Hans Preisendanz between 1989 and 1992, a CFC - and HFC -free refrigeration unit for refrigerators .

Life

Rosin studied medicine , was approved in 1968 and received his doctorate in Hamburg in 1970 . In 1975 he completed his habilitation and received the Venia legendi for microbiology and virology at the Heinrich Heine University in Düsseldorf . From 1979 he worked there as a professor of microbiology and virology. From 1987 to 1988 he was acting as acting representative of the chair for medicine, microbiology and virology. In 1989, Rosin took over the management of the Institute for Medical Microbiology and Virology at the University of Dortmund and was director of the facility in Moorenstrasse until its dissolution in 2000.

Rosin tried to find a less questionable substitute for the refrigerants CFC and PFC. He took the view that the HFC patented by DuPont , which was supposed to replace CFCs, interfered in a dangerous manner with the citric acid cycle and thus posed a major threat to the biosphere. Together with Preisendanz, Rosin succeeded in finding a halogen-free refrigerant mixture from several hydrocarbons . However, the household appliance industry showed little interest in the new process and stuck to conventional refrigerants.

Together with Greenpeace , after the end of the GDR , it was possible to implement the “ Dortmund mix ” with the VEB DKK Scharfenstein, the later Foron , which tried to assert itself on the German market as a whole. In 1993 Foron Hausgeräte GmbH was awarded the German Environment Prize for the implementation of the coolant application. After the market launch of the first “Greenfreeze” eco refrigerator from Foron, most refrigerator manufacturers developed similar systems.

Together with the toxicologist Otmar Wassermann , Rosin worked on a new recycling process for plastics and electronic scrap . The so-called cryo-recycling for material recycling by Rosin has not yet been implemented in a pilot plant.

Rosin lives in Erkrath today .

Honors

In 2000, Rosin and Preisendanz received the Federal Cross of Merit for the implementation of CFC-free cooling technology.
