<DIV><FONT face=Arial size=2>Here is another problem. How can I approach

<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

<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. If you'd like to discuss
further, feel free to call me.</FONT></SPAN></DIV>

<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.
</FONT></DIV>
<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>
