[esp-r] Re: heating/cooling control in two different zones but in one model

[Pueltz, Gunter]

Dear Monika,
 
you should define a (may be identical) zone control function for every zone,
which you want to control.
Afterwards you can link each control function ONCE to it´s corresponding
zone ....
 
This will work in ESP -r because I did it several times and succeeded .....
 
Best Regards,
Gunter

Subject: [esp-r] heating/cooling control in two different zones but in one
model


Dear all,
 
did anyone have experience with the zone controller "basic controller for
heating/cooling" in two different zones but in one model?

 

My model consists of three zones: one zone has no control and in the other
two zones I would like to fix the temperature and humidity (different values
in both zones). The three zones are coupled with an air flow network.

If I used only for one zone a "basic controller for heating/cooling" and fix
the temperature and humidity, the simulation runs. But when I control the
second zone with a second "basic controller for heating/cooling" and fixed
temperature/humidity, either,  the simulation fails with following text:

 

mzpst1: problem with flux assignments

 

Did anyone know the problem? What can I do?

 

Best regards

Monika
