size=2>I have a CDQ taking in 100% Outdoor Air, and providing this air to
two air handling units. There is both a heat recovery enthalpy wheel and a water
side economizer in the CDQ and when these are applied, in the month's of
March, April, and November, my simulation outputs large (seemingly
random) spikes in Total system supply air flow rate (cfm) for the CDQ and
in-turn the ventilation fans providing the power. But when I disconnect these
two devices I get nice results. Would <SPAN

be?</FONT></SPAN></DIV></DIV>
