<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Does anyone in DOE2 Land know how to get DOE2.1E to allow the
chilled water coil leaving air temperature to be 35 degrees F for special space
dehumidification requirements? I’ve specified in PLANT input a hermetic
centrifugal chiller with a cooling tower to deliver 32 degree (the minimum
allowed) chilled water. I’ve specified no piping losses in PLANT, and
a coil bypass factor of 0.01 with a blow-through fan and a chilled water coil water-side
delta-t of 7 degrees (the minimum allowed) in SYSTEMS. Also, DOE2.1Ev132 will
not allow me to specify a coil chilled water supply temperature below 35
degrees under any circumstances that I know of. Then the code requires at
least a 6 degree coil water-to-air temperature differential, which limits me to
a 41 degrees F coil leaving air temperature. I know that glycol chillers
can go lower than 32 degrees, chilled water can be delivered at below 35 degrees
and beefier coils can beat a 6 degree differential, but can DOE2 be coaxed somehow
to simulate these extremes?<o:p></o:p></span></font></p>
