Heat Recovery Unit hooked up with AC

[wulianlian]

I am a college student doing a report on AC hot water heat recovery
systems. Several AC professionals and alternative energy specialist
tell me that in the 80's they recommended and installed many of these
heat recovery units, but they no longer recommend them or install
very many. They said that modern AC units make heat recovery less
beneficial and can, in some cases, create problems with the AC
systems. After looking into the question, I am having difficulty
understanding what are the problems with the heat recovery systems as
an add-on to modern AC units. Can some of you AC professionals out
there please point out some of the specific problems as you understand them?

Are you talking about recovering the waste heat during cooling cycles?
