Hello World!

I am trying to simulate a thermal solar energy system which is coupled with acummulation tanks for storage and absorption chiller for cooling loads in summer season and heater units for winter season in EnergyPlus.

However, I cannot find the Hot Water Storage System. As I found an answer for a problem which looks like my case, it is said that Boiler can be used as Hot Water Storage system with setting the heater capacity as zero.

However I need 2 Inlet and 2 Outlet Component (as heat exchanger), 1 inlet and outlet serves to heating the water inside the tank like a heating coil; the other inlet and outlet serves to demand side.

How can I add an acummulation tank into my model?

Thanks

The water heaters can also be used as storage tanks. Both the WaterHeater:Mixed and WaterHeater:Stratified have 2 sets of inlet/outlet nodes. The flow through these nodes will be used to calculate the resulting tank temperature.

WaterHeater:Mixed,
 A14, \field Use Side Inlet Node Name
 A15, \field Use Side Outlet Node Name
 A16, \field Source Side Inlet Node Name
 A17, \field Source Side Outlet Node Name

WaterHeater:Stratified,
 A16, \field Use Side Inlet Node Name
 A17, \field Use Side Outlet Node Name
 A18, \field Source Side Inlet Node Name
 A19, \field Source Side Outlet Node Name
