<p class="MsoNormal"><span style="color:#1F497D">When I model thermal storage, I
typically set up equipment controls to control when the Ice tank will be
charging and discharging. In the discharge sequence, if you set the chiller to
sequence 2, the ice storage tank will be discharged first. At the bottom of the
equipment controls screen, you can input the correct thermal storage
information.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">After I create the equipment
controls, I typically create a load management for the cooling equipment which
tells the equipment when to charge and when to discharge. You will have to
create a FLAG schedule for the load management equipment control.<o:p></o:p></span></p>

<p class="MsoNormal">Hi, everyone :<o:p></o:p></p>
<p class="MsoNormal">When I finished a thermal storage system, I found the
thermal Storage can¡¯t be control by ¡°Equipment control¡± list.
Like the illustration below, the list only content Chillers on the loops. <o:p></o:p></p>
<p class="MsoNormal">What I want is to make sure the Thermal Storage energy
should be used by control, at most of the cases it should be used first, but on
the warmest day , It should be used at 3~5PM to prevent the main chiller
can¡¯t deal with the cooling load.<o:p></o:p></p>
<p class="MsoNormal">Who can take some light on this ? Any suggestion should be
appreciated.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you very much.<o:p></o:p></p>
