<div dir="ltr"><p class="MsoNormal"><b>Hi,</b></p><p class="MsoNormal"><br></p>
<p class="MsoNormal">Our working project has One (1) central chiller plant (4
nos. of chiller + 4 nos. primary & secondary pump + 4 Cooling Tower) which
is serving to the both phase 1 & phase 2 area…whereas currently we are
working on the phase2 model.</p>
<p class="MsoNormal"><br></p><p class="MsoNormal">Hence our question is-<b>What capacity & efficiency to be
consider for modelling phase2 chillers, pump & cooling tower in E-quest?</b></p><p class="MsoNormal"><br></p>
<p class="MsoNormal">As per the USGBC guidelines for the <b>treatment of district
cooling</b>, we need to calculate average efficiency. So can anyone guide us on <b>how
to calculate the average efficiency? </b></p><p class="MsoNormal"><b><br></b></p>
<p class="MsoNormal">However the same guidelines suggest to consider the <b>default
efficiencies</b> in case of unavailability of average <a href="http://efficiency.it">efficiency.it</a> says COP of 4.4
for the total cooling plant average efficiency (including cooling towers &
primary pumps).<b>Can anyone guide us on how to take it (default efficiency) into account for all the
system while modelling in Equest?</b></p><p class="MsoNormal"><b><br></b></p><p class="MsoNormal"><b><br></b></p><p class="MsoNormal"><b>Regards,</b></p><p class="MsoNormal"><b>Vishal</b></p><p class="MsoNormal"></p></div>
