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<o:p></o:p></span></p></div></div></div><br clear="both">
