Hi all,

is there a template available to prepare the modeling of large scale
building projects?
My template is fine for up to 15 zones, but I am looking for something of
50 zones (including 3 floors) or more ...

Thanks,

wang

Subject: Re: [TRNSYS-users] online plotter in CombiSys
 Shuai,
  The *** syntax is a special code recognized by the TRNSYS input file
processor to mean "append the name of the input file onto the specified
extension"

before modification of the input file, you should find files called
combisys.ou1, combiSys.ou2, etc.

  By deleting one of the three asterisks the processor now thinks that the
output file names should be:

**.ou1, **.ou2. It will no longer append the name of the input file onto
the specified extension.
Best,
 David

Dear all,

 I downloaded  Combisys demo and found it is pretty easy to use as an
education tool
to show the basic operation of solar combi-system.
I even discussed with some students in my lesson about the content of trd
file,
sth like: how the data transfer between types, and how to add our cities
into the demo to extend its function,
and how to add some solar collector types they obtained from google to the
demo.
To be honest, I can feel they really like this demo.
One of them asked me a question about how to output the results of two
online plotters in the system.
Actually, the system, described in combisys.trd demo file, contains:

 a. 2 online plotters: unit 41, type 65, output file: Assign ***.ou1
                              unit 45, type 65, output file: Assign ***.ou2
They are mainly used for showing the operation information of the system.
In the original content of combisys.trd file, they are set "no need to
output result file", just used as two "monitors".

 b. Unit 51, Type 24, Monthly Integrator + Unit 52, Type 25, Printer
they can be considered as two partners, and work together to output file:
 Assign ***.out

 c. Unit 50 Type 28 Simulation Summary
output file: Assign ***.sum

 The thing is
we remove the "*" before the output statement "Assign ***.ou1" and ou2 in
the related groups of online plotters, so that the demo can output these
two result  files.
however, we found no data is in the ou1 and ou2 file, they are blank.
and other output files works.

 So, we did some assumption analysis ( actually, it likes a simple brain
storm ) about why it happens:
a.  no data are calculated out by demo: that is not true, because online
plotter works very, both of them. all the performance curves are shown
every calculation step.
b. online plotters only show the results, not record the data into output
file:

 we thought that is also not true. The script regarding the online plotter
is shown below:

 *|[OL2|
*
*
Unit 45 Type 65 Online plotter
*
Parameters 10   ! Here shows 10 parameters of type 65, OFF=0 means display
online; LU=-1 , we guess it is means logical unit =-1?
*

SolFrac
*
*
Labels 5
*
kJ %
Energy
Percentage
Integrated
*
Assign ***.ou2 22 ! here we just remove the header sign "*".
*
*|]

 c. this online plotter is type 65c, means a online plotter without file:
 because "assign" statement has already been contained, so it seems not to
be a right answer.
d.  the post-processing will erase the data in the ou1 and ou2 files: that
is a interesting idea from one student,  but we checked the "out"  folder,
bat and txt file did not support this assumption.

 In a summary, we have no idea about why two output files-ou1 and ou2 are
blank.
Thus, I send this email to all of you for a help.
Any comments and advise will be helpful to us.

 Thanks,

Subject: Re: [TRNSYS-users] Type 927, Number of specified flows
 Richard,
  It is important to clarify that the data file for Type927 required at
least two *values *of source and load flow rates in order for the TRNSYS
kernel routine that reads the data file to interpolate correctly. A
modification has been made to TRNSYS 17.1 that allows users to specify only
one value for any of the "independent variables" if they so choose.

  The easiest thing to do in Trnsys17.0.x and earlier is simply to copy the
data for the flow rates that you do have and paste it for another
(arbitrary) flow rate. Essentially this just indicates in the data file
that there is no performance dependence on a changing flow rate. Probably
not a great assumption but at least the simulation would run.

Kind regards,
 David

 Hi.****

Is it necessary to specify three load and source flows in the external file
of type 927? Because it seems like it should be possible to only have two
but when I try to simulate I get two errors ****

*“The referenced Unit has a bad parameter value.*

*Reported information  : Parameter # 11, Reported Problem: There must be at
least two source flow rates.” *

The problem is that I have specified two load and source flows.****

Has anyone encountered this problem?****
