[TRNSYS-users] Heat exchangers network modelling problem



Hi all,

 

I’m modelling a system using a network of heat exchangers for heat recovery purposes (see attached picture).

 

Heat exchanger calculations seems to be repeated many times for a given time-step and their temperatures re-calculated within the same time-step while other components on that model are not updated until the next time step (as it should be). Problem observed at the exchanger is leading to wrong temperature calculations. From our understanding types should be only be called once every time-step, furthermore heat exchangers network should be re-calculated taking the temperature from connecting models. Is there any option or any idea to bring light on this problem?

 

Kinds regards
