Hi Otto,
your method is very illustrative. However, my project seems still not to work.
I have set the equipment control and load management based on your method, and the load management flag is also been set. The problem is that the charging chiller does not work at night, which is set in my schedule! While the cooling tower works at night! I cannot figure out why it is the result. How do you think the problem may be in?
thanks

Joey,

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.

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.

If anyone has a better or more detailed technique of modeling thermal storage please add to the conversation.

Hi, everyone :

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.

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.

Who can take some light on this ? Any suggestion should be appreciated.

Thank you very much.

Joey.
