Saw a couple of ads about this new construction of tube for aircon/refrig systems and wondered if anyone has been using it yet and what are their experiences with it.
AFAIK, these two metals have different co-efficients of expansion, so will expand/contract to differing lengths when heated/cooled. And that constant stress going on during the life of a system, repeatedly expanding and contracting, must take it's toll before too long.
And if used on an air heat-exchanger, doesn't the ali tarnish in a different way to copper and reduce heat transfer?
Guess it's a bit early to answer these questions but maybe someone already has come up against it(?)
