[TRNSYS-users] Conversion from Trnsys15 to Trnsys16

Wed Feb 4 10:24:23 PST 2009

Hello,

I’m trying
to convert Trnsys15 types to Trnsys16 types. So I followed the instructions
from the manual:

!DEC$ATRIBUTES
     DLLEXPORT::TYPE154

If(INFO(7)==-2)then

INFO(12)=15

return 1 (do I really have to use return 1?)

     end
if

If(INFO(7)==-1)then

INFO(6)=20 (value by default according to the manual)

INFO(9)=0

call SetStorageSize

call TYPECK(1,INFO,NI,NP,ND)  (IOPT=1)

call RCHECK(INFO,YCHECK,OCHECK)

return 1

    end
if

If(TIME==TIME0)then

A=PAR(1)

.              .

.              .

.              .

E=PAR(5)

OUT(1)=initial condition or 0

.

.

.

OUT(4)=initial condition or 0

    return
1

end if

If(INFO(13)>0)then

                return 1

            end if

If(INFO(8)==-1)then

                return 1

            end if

My problem
is that due to this conversion Trnsys mixes up the parameters for my type (Type154). I
used the debugger to find out where is the problem. Next, I landed on Proc.for
(I checked the parameters with quick watch, everything is ok) and from there I got to
Exec.for where beings the checking of every unit in my simulation, everything
is ok until I begin to check my type (written originally in Trnsys 15).

Proc.for(good
parameters)→ Exec.for (good parameters)→CallTypes.for (good
parameters)→TYPE00.for (good parameters)→TYPE154.for(mixed up
parameters)→Exec.for(good parameters)

Has anyone
had this problem before? Frankly I have no idea how to solve this.I've tried everything I could think of and nothing seems to be working.

Any help
shall be appreciated.

Chun Kwong,

  You have to use the correct mode of Type89 (Type89d in this case). In
TRNSYS 16, the start time is the hour of the year at the start of the
simulation (0 to start at the very beginning of the year, 1 if you want
to start on January 1 at 1AM, 744 if you want to start on February 1 at
midnight). In TRNSYS 15 it was a bit different. If you are using TRNSYS
15, let me know and I will explain in more detail.

Regards,

 David

  Dear Trnsys users.

I try to perform a simulation by specifying a simulation start time other than 0
or 1.  However, I find that the weather data read using Type89 seems to start
just from the beginning of the data file no matter what simulation start time I
have specified.  What is then the actual meaning of this start time?  If I want
to start a simulation not at the beginning of a year, what should I do?  Your
reply is highly appreciated.  Thank you!

Dear TRNSYS-users, 

Does someone know if it is possible to get the 
conductive heat flux 
through a wall directly from TRNSYS? Or is it only 
possible to consider
the total heat flux and the heat flux forom 
radiation separate and then 
subtract the first from the second. 

Thanks in advance.

Best regards

Dear users,

Does anybody knows if Trnsys 17 leads to changes in trnflow ? I’d like to get
Trnflow but I don’t want to buy a new version in just a few months…

Dear David and TRNSYS users  
Thanks again for your helpful advice.  

I think I found the reason that gives me strange results. I created a *.tm2 file of meteorological data using Meteonorm software. The created file gives the radiation in W/m^2. The component that reads this file (type109-TMY2), has by default the unit of solar radiation in kj/hrm^2. Have you got any idea about how can I change this, without changing the whole proforma (this is because the proforma has already a lot of changes that I don’t want to be change in this project). 

Is there any way to view this *.tm2 file? (maybe another software?). I connect it with type65a, in order to view some data, but it seems to be quite different in comparison to the preview results of Meteonorm. I think that this is the reason that gives me “weird” results in my simulation. 

Thank you for your helpful advices. 

Best regards,

Artemi Spanaki

Artemi,

TMY2 files are just plain text files, you can open them in 
Notepad. However, due to the format, they're difficult to read like that. Excel 
can open them and be set up to split the data fields properly, or you can just 
use a template like this one: http://sel.me.wisc.edu/trnsys/weather/tmy2.xls

Type 109 knows that the input from a TMY2 file is in W/m2, and 
converts its output for kJ/hm2, you shouldn't have to change anything for it to 
work properly. What exactly is the problem you're getting?
