<div class=Section1>
<p class=MsoNormal>Does anyone have a suggestion on how to model a heat pump
chiller with chilled water coils in zone exhaust airstreams that rejects its
heat to a water loop to preheat incoming outside air to an air handling unit.
The idea is to cool the exhaust airstreams from room temperature to say 50F,
kind of normal chilled water cooling ranges for the exhaust side. The chiller
needs to be able to make say 140F hot water for preheating use. My air handling
systems are 100% outside air, it’s an older laboratory building. The heat
recovery chiller isn’t appropriate because I don’t have internal
loads requiring mechanical cooling in the winter, the 100% outside air pretty
much takes care of those. Any experience or suggestion anyone might have would
be appreciated.<o:p></o:p></p>
