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>

Re: [BLDG-SIM] Closed circuit cooling tower in

<DIV><FONT face=Arial size=2>Thanks to everybody for helping with my river
water cooling problem. I found that using hourly output and programming
excell spreadsheet was the way to go.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Here is another problem. How can I
approach modeling a closed circuit cooling tower in

<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>

<DIV><SPAN class=151510117-18032004><FONT face=Arial color=#0000ff
size=2>It 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.

<DIV><FONT face=Arial size=2>Unfortunately I am using Doe2.1E, where I

<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>I am working on a project that
considers utilizing river water instead of a conventional cooling

this be simulated in DOE2.1? (Basically, somehow I need to reset
entering condenser water temperature to that of a river
water).</FONT></DIV>
