[TRNSYS-users] RE : Type157 w/schedules

[keilholz, werner]

Dear Yoshihiko,
 
When you are coupling an existing COMIS project with a TRNSYS project, only the TRNSYS time loop is executed when the simulation is run from the TRNSYS project. Therefore, schedules defined in COMIS will not be executed. (They are only executed when you run the COMIS project using 'Edit Air Flow network' when right-clicking on type 157). 
 
If you wish to open and close windows in the air flow network (or change fan speeds, etc.), you have to use and additional input to type 157. These additional inputs already exist in your project : they are called 
'Actual Factor for links with schedules-N'
(where N is the number of the link in the COMIS air flow network definition).
 
So now you only have to connect these inputs to a schedule defined in TRNSYS (not in COMIS). For example, you can use a forcing function (Utilities/Forcing Function/General/Type14h) to define the schedule. Then connect the output of type 14 to the input of type 157. 
 
The meaning of the value depends of the component used in the COMIS airflow network for link N : an opening factor (0..1) for windows, a fan speed for fans, etc. (see COMIS User Guide in 
.\Trnsys16\Studio\Lib\comis-demo\Documentation
 
or if you have COMIS in 
\comis32\Documentation
 
Hope this helps,
 
Werner

Dear TRNSYS Users,

I'm trying to simulate about cross-ventilated building
with TRNSYS 16.01.0003 and COMIS 3.2.

I would like you to teach me how to set the opening and shutting schedule of windows
in the Coupled Project (TRNSYS-COMIS).

In the COMIS stand alone, the schedule work normally.
However, it does not work in the Coupled Project, windows are always opened...
