That's because of the potential interaction between the metal of the heat exchanger and the solutes in the working fluid. Newer & better stuff nowadays, they no longer have to be held perfectly level. The issue now is that the exhaust has to be vented. They do work better if level, though. DSK they work on the basis of Ammonia cooling. See http://www.nh3tech.org/absorption.html |
