<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=784223614-24032004>What
front end are you using to insulate you from having to deal with text at the
BDL level? Our office has been using Visual DOE for about 7 years now
and the central plant editor allows you to specify a closed cooling
tower. Anyway, I did a quick sample run specifying a low efficiency (as
noted by the high approach) closed tower and the BDL text the program wrote
looks something like what I have below. If your GUI front end doesn't
allow a closed tower, you might have to roll up your sleeves and insert
similar text into the input file. Make sure to change parameters as
appropriate.</SPAN></FONT></DIV>

<DIV><SPAN class=151510117-18032004><FONT face=Arial color=#0000ff
size=2>I have become a big fan of the hourly output report capabilities of
DOE-2 for presentation purposes, troubleshooting, and to handle situations
such as yours where I'm not aware of how to approach the solution within
DOE-2.</FONT></SPAN></DIV>

<DIV><SPAN class=151510117-18032004><FONT face=Arial color=#0000ff
size=2>You could probably run an hourly report to export systems tons
load, CHW supply temperature, and any other variables you might need (CHW
pump kW, condenser pump kW, lighting kW, etc.) and dump the 8760 hours of
data into an Excel file. Based on your CHW pump kW, you might want
to add a column to account for pump heat to give you total cooling load
seen by the chiller.</FONT></SPAN></DIV>
<DIV><SPAN class=151510117-18032004><FONT face=Arial color=#0000ff
size=2></FONT></SPAN> </DIV>
<DIV><SPAN class=151510117-18032004><FONT face=Arial color=#0000ff
size=2>Then you need to add 3 columns to calculate from the DOE chiller
curve coefficients the multiplier for capacity based on CHW and CW temp.
(I assume you have a good idea of the variation in river water temp. by
season), multiplier for EIR based on the water temperatures, and
EIR-FPLR. The product of these three values should give you the
hourly EIR. Add another column so that based on the total tons
cooling load, you can then calculate chiller kW from the hourly
EIR.</FONT></SPAN></DIV>

concept to set up and should give you the results you desire. If

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Unfortunately I am using Doe2.1E, where I
cannot schedule loop temperatures. BTW, is it possible to write a
custom function to access the PLANT? It does look like I can
only use custom functions to modify computations in Loads and Systems.

<DIV><FONT face=Arial size=2>Any ideas?</FONT></DIV>

<DIV><FONT face=Arial size=2>Konstantin,</FONT></DIV>
<DIV><FONT face=Arial size=2>Not 100% sure, but I think you should be
able to schedule the loop temperature. Create day/week/year
schedules and input the appropriate variation in river water temp, use
that for loop temp.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I know you can do this for ground source
loop temperature for a WLHP system, so it should be applicable to CW
loop.</FONT></DIV>

<DIV><FONT face=Arial size=2>Hello,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am working on a project that
considers utilizing river water instead of a conventional cooling
tower condenser water. Does anyone have an idea how could this
be simulated in DOE2.1? (Basically, somehow I need to reset entering
condenser water temperature to that of a river
water).</FONT></DIV>
