<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Has anyone ever looked at or designed a system where the
cooling tower was used for heat recovery? i.e. in most cases the exhaust from
the building is routed via an energy or heat recovery unit for energy recovery
and in the process the incoming outside air is tempered. This exhaust air could
be routed to the cooling tower air supply stream. The exhaust from the building
is nominally at 75 deg F and 50% RH which would make the cooling tower operate
efficiently during the summer. The downside to this is that it would not work
during the winter and also the exhaust air flow is generally a lot smaller than
the cooling tower cfm. Not sure if there are any code restrictions to this sort
of thing. <o:p></o:p></span></font></p>
