Re: [TRNSYS-users] Type 4c

Hadi,

If you have stratification enabled in your storage tank (multiple nodes), and your hot water from solar is going to the top of the tank, and your water that is going to the load is exiting from the top of the tank, then this will happen naturally.  If you want the solar hot water to go directly to the load if it’s hot enough then you’ll need to introduce a series of diverters and mixers, along with appropriate controls, to make that happen.

How can I make the tank provide the water at a temperature higher than the setpoint temperature when that is achieved by the solar system?
