Dear users,
I am finding that energy balance issues with type 362. I find that the energy balance does not sum zero in some conditions, I have tooled around finding that the following conditions cause the error>
·
Variable supply temperature.
·
Step signal on mass flow control signal (flow goes from 0 to full), the energy balance fails on first time steps after “ON” signal or first time steps after “OFF”.
I feel there is a convergence problem that does not appear on the list file. Supporting this, I tried changing the “convergence tolerance”, finding less errors on the energy balance increasing it (from default 0.0001
to 0.001).
I am using type362 in trnsys17 project with a simple room modelled with type 56.
Has anyone experienced this problem? How can it be solved?
