<div dir="ltr">Dear eQuest users,<br><div><br>I need help in thermal storage modelling. The issue which I have faced is: <br> <br>The
project have 4 chiller (2200 TR each). To reduce peak load in day time,
I have modeled thermal storage of 8000 TR-h (95 MBTU) with charging and
discharging rate at 11.9 MBTU/h and 12 MBTU/h. To size each chiller
capacity, I modeled chillers as autosize in both case (with and without
thermal storage).<br><br>When there is no thermal storage the
chiller sizing is 2386 TR each (4 chiller) with zero unmet hours and
When I modeled thermal storage and a chiller dedicated to thermal
storage and other three are working as supporting to thermal storage.
The chiller size in this case are 3 chillers of 3496 TR and one chiller
of 1026 TR and 5467 unmet hours.<br><br><br>I am following
procedure as mentioned in tutorial (attached). However, I got unmet hours and
higher cooling tonnage than without thermal storage case.<br><br>Please help me to sort out this problem. <br><br>Regards,<br>Mayank Bhatnagar<br>Energy Analyst</div></div>
