[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
