ice storage in openstudio does not change results

edit

thanks for your suggestions. I added it. I have read all the thread, a few are having the same problem as mine and have no solution.

Aha - most examples I see have the ice storage in parallel; you have it in series here. Unless control is setup properly, flow always goes through the chiller. Try adding in parallel.

I tried the parrallel way too, do I just put the ice storage under the chiller? Or I added another chiller in parallel to the existing chiller and but the ice storage downstream? I see the E+ example file did it this way and only let one chiller one at the same time to represent one chiller with two chiller modeled.

I think you want one chiller and one tank, in parallel. Also - what are the units of tank capacity? Maybe its too small?

I tried similar configuration with the E+ example file but the openstudio just wont turn on the ice storage. I put a CHW setpoint manager right after the chiller to make it produce low temp CHW (w/ glycol)to charge ice storage but it ignore the setpoint manager..
