The dry cooler has only the circulation pump, then two variable speed fans which modulate to maintain return water temp. Initially I figured out how to add a second chiller to the loop, and make it run only below the designated OAT using Equipment Controls and Load management I seem to see the savings (using a default EIR of nearly zero for testing purposes) . I am hopeful that I can then create a custom performance curve for this dry cooler, basing the energy consumption on load and OAT. Alternately if that is too complicated, I think OAT would be a reasonable backup plan. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Does anyone have any guidance on creating such a performance curve in this situation?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks<o:p></o:p></p><p class=MsoNormal>Laura<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
