EnergyPlus desperatley needs a condenser water thermal energy storage object

[lincolnharmer]

When trying to design an all-electric building HVAC system, condenser water thermal storage is an attractive option. See this recent ASHRAE article for reference: October2021_12-27_Gill (1).pdf

Currently E+ doesn't have a thermal storage object which can be added to a condenser water loop as far as I know. Perhaps the chilled water thermal storage object can be used as a work around?

what about trying a user defined plant component?

where is that object documented? I couldn't find it in the input/output reference

[lincolnharmer]

sorry, I found it

[lincolnharmer]

thanks! this looks a like a possible avenue. This could be impleented in OpenStudio but I will need to add the WaterUse:Storage object via an E+ measure as that isn't supported by OpenStudio directly yet.

Also, the WaterHeater:* objects can be used for storage. See example files HeatRecovery*.idf. The water heater objects can be a simple storage tank by setting the heater capacity to zero.

thanks, I didn't realize we could use the waterheater objects like this but that makes a lot of sense.
