Re: [TRNSYS-users] solar domestic hot water example diverter



Benjamin,
 It is not clear from your email which example you are starting from or which diverting valve component you are referring to. If you are referring to the example in ..\Trnsys17\Examples\ then I would suggest that you look at the documentation for Type11 whose algorithms are explained in the Type11 section of the 04-MathematicalReference. If you are speaking of a different example or if you are trying to use the tempering valve controller in the TESS Controls library (Type953) then again I would refer you to the documentation of that component. It can be found in ..\Trnsys17\Tess Models\Documentation\02-ControlsLibraryMathematicalReference.pdf

Thanks Jeff, but how is the contral signal decided how is it calculated so the portion of cold water with the hot water.

 

Best regards,

It's a tempering valve to limit the temperature of the water being delivered to the load.  A portion of the  cool mains water bypasses the tank and mixes back in with the hot water leaving the tank.

Dear sir/madam,

 

I am trying to make my own design of a building integrated hybrid photovoltaic system for on a skyscraper. Now you already provide a  solar domestic hot water system so I decided to use that as basic and change mine with the help of this one. But one thing I don’t understand is how the diverter works. You have your load profile and then you let It go through the diverter, who seperates it into two flow one to the tee piece and one to the tank. Me is not totally clear how it is decided when it goes to the tank or when to the Tee Piece. I found out about the control signal but I monitored this one as well but did not understand how it is calculated because the formula in the small description is wrong.

 

I hope someone can help me and I don’t understand why the diverter is needed. Why will the load profile not go directly to the tank I expected that is was actually a control signal or data line but here is looks a flow.

 

I hope to hear from you soon.

 

Best regards,

 

Benjamin Stobbe
