Today I had the opportunity to listen to a presentation from a professor from Beijing University of Technology’s Department of Building Environment and Faculty Engineering on a new type of flat plate solar collector (for residential hot water). By using a novel collector and absorber, various tests were described when tinkering with amibeint air temperature, pressure in chambers and tank temperature -which I did not understand all of. I shared lessons Rich Seifert found out down the road.
But the diagrams were fantastic and well labeled so that the efficiencies were understood at a comprehensive level. It was a very nice presentation in that it had spec diagrams, and photos of the actual units being tested in the field. This was a nice way to explain things in theory and reality…..
The conference has been a good mixture and quite an interdisciplinary venue.
