The new OpenStudio version has the option to incorporate Ice Storage in HVAC systems , i need to know if anyone has used this option and integrated into an existing building model?

Did you have a specific question about how to use it? It can be added in the GUI to the supply side of a plant loop by dragging it in fro the library. If you need guidance in adding it using a measure I can help with that as well.

Hello David,Thank you very much for the response i am using a default Secondary School Model 90.1-2010-SecondarySchool-ASHRAE 169-2006-5A and need to insert the ice-storage unit into it. If you could direct me into incorporate that i would be thankful. I was looking for a suitable measure as well but did not find one as yet.

Hello David , following up on the question...is there a suitable measure to be applied as ice-storage into a pre-determined building as in the example i have mentioned above?

The major issue is that whether the current ice storage model is equipped with its own chiller or the cooling plant loop should be changed further to accommodate a chiller and complementary bypass system ?.

Here is minimal ruby code required to add this object to the model.

chilled_plant = model.getChillerElectricEIRs.first.plantLoop.get
thermal_storage = OpenStudio::Model::ThermalStorageIceDetailed.new(model)
chilled_plant.addSupplyBranchForComponent(thermal_storage)

And here is what the model objects look like after it is made.

Dear @David Goldwasser, the OS layout seems a little bit misleading to me. Does it really work like this? because I cannot think of a proper loop for the ice storage charging cycle. Another issue that bothers me is that E+ available ice storage loops are somehow different from commercial ones. Isn't the propose of the E+ simulation further assessment of existing models?

Regards
