Dear Experts.
We get convergence
problem in Type 56. According to our investigation source of
error is sudden increase of ventilation flow in our schedule
and ventilation air temperature about 3 K lower then room
air temperature.
We would like to keep
this control schedule and the same time avoid convergence
problem.
So far we have increase
indoor air heat capacity in zones (five times), it help a
bit.
Do you have any other
ideas what we could do?
Should we change
something in Control Cards?
Best,
Karol
