Re: [TRNSYS-users] Trnsys 17 coupling Contam: multipliers



Moises,
If you are working with TRNSYS 17 then that is good! Trnsys17 has a more logical way of dealing with those multipliers. Essentially the control signals that open or close a certain path become inputs to the model. Please refer to the Type97 description in the 04-Mathematical Reference manual for instructions on how to pass your control variables to Type97; some manual editing of the *.air file is necessary but it is also pretty straight forward.
Kind regards,
David

Hi,

I am trying to simulate a mechanical system with variable section air intakes using Trnsys + Contam (Type97). I want to define the variation of the section through "multipliers."

The problem is that when I work with TRNSYS 17, the "multipliers" don't appear. Am I doing something wrong?

In the example "CombinedThermalAirflow" there are no "multipliers" and in the example "CombinedThermalAirflow_AHU" there is only one "multiplier" and there four paths. When I modify this last file, this "multiplier" disappears. If I work with the same files in TRNSYS 16, the "multipliers" work, but I can't simulate the mechanical ventilation systems.

Can anyone help me?

Thanks,

Moises Odriozola.
