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>

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

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

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>

might end up being a big spreadsheet, but it's really simple in concept to
set up and should give you the results you desire. If you'd like to

<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>
