The Sci. Engr. Heat-Vent- AC
Interesting Threads Collection

Sci.engr.heat-vent-ac is a Usenet group which came on-line in May of 1995, for the purpose of providing a forum for people in HVAC/R related fields to discuss technology, ideas, questions, problems, theories, concepts, etc. Here are some of the discussions !

Any topic lines you see here that are not yet 'linked' are waiting for some kind soul to write an article, or start a good thread in the group ! Any topic lines you don't see listed are waiting for the same thing, so go ahead and start a discussion ! :~)
