[TRNSYS-users] Convergence problem between trnsys immersed heat exchanger input & heat input computed between inlet & outlet connection

[Usman Ijaz Dar]

I am currently using Trnsys storage tank Type 60 with immersed heat exchanger connected to a heat source. My question is related to energy imbalance between the heat exchanger which is computed inside the storage tank model and energy input computed by different in heat exchanger inlet and outlet. In my case, I am running the heat exchanger at high flow rates i.e. 600 l/h which is reasonably high and no convergence warning occurs related to internal routine of heat exchanger T_o. Could you please explain the imbalance ?
