Hmmmm.  The 2007 (26th Edition) of the ACGIH manual said to "avoid" heat wheels.  And the 2010 (27th Edition) included the even stronger prohibition I quoted in a previous post.  So if there is some rule promulgated in 2011, I'd love to know about it.  I find it hard to talk LEED-besotted architects out of the wheels and would love to have another reference.

There is a new (January, 2011) restriction against using heat wheels to recover heat from exhaust generated by chemical hoods. I don't have the reference handy but will send it to you tomorrow.
