Revision history [back]

Hello,

I have been looking around the forum trying to figure out how to set up hot water thermal storage. I am working on a simulation for a greenhouse that uses a hot water radiant floor. The hot water is supplied by a boiler. So I have currently put together a plant loop using a boiler, HW setpoint manager, low temp radiant var flow object, and a variable speed pump. This is very similar to what the actual system is.

However, the greenhouse also has a very large hot water storage tank. Hot water can be stored there in case not all of the hot water is required at a certain time to heat the greenhouse, or if the greenhouse operator wants to run the boiler to get CO2 off the stack and pump that into the greenhouse for the plants while the hot water gets stored in the tank for later use.

I am wonder how I would go about doing this. I see from the HVAC System Requests and Priorities spreadsheet that a Thermal Storage - Hot Water Storage object exists but I do not see it in OpenStudio. I am currently using OS 1.9.0.

So far I have tried using water heaters on the demand side of the loop with the boiler on the supply side but that hasn't worked.

I'm grateful for any suggestions and help. Does anyone know if maybe the Thermal Storage Hot Water Storage object has been developed but not yet released?

Thank you.
