<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I have a need to simulate the
performance of a hypothetical fluid cooler applied to a condenser of a
distillation process. I am trying to determine the energy consumption that is
being avoided by the installation of heat exchangers that are effectively
serving the condensing function. I have data to determine actual hourly values
of heat rejection (BTU/hr), fluid (not water) temperatures and flow rates and
should be able to obtain hourly weather data for the period corresponding to the
data. I can get design values for the fluid cooler from a vendor. I only need to
determine the energy consumed by the fluid cooler – no other building energy is
of interest. I am thinking I may be able to do this in eQuest, assigning a
process load to the fluid cooler after developing a schedule from the data I
have and putting a meter on the fluid cooler. My concerns are that the fluid is
not water (I have been unsuccessful in the past specifying non-H2O cooling
fluids) and that the temperatures (cooling from 235 degF to 200 degF) may be out
of range for the algorithms. Anyone see any flaws in this approach before I
propose it?<o:p></o:p></SPAN></FONT></P>
