Frédéry,
the TrnsysConstants file is in the ..\Trnsys16\SourceCode\Kernel
directory. The process for recompiling the DLL depends on which
compiler you are using. The two most likely are the Compaq Visual
Fortran compiler or the Intel Visual Fortran compiler. If you do not
have a Fortran compiler then you will need to ask your distributor to
create a TRNDll.dll with a higher limit on the number of equations for
you.
Kind regards,
David

Dear trnsys users,
I'm simulating an energetic concept on trnsys simulation studio and
i've this error message:
"TRNSYS message 14; the trnsys processor has reported an error while
trying to process EQUATIONS and CONSTANTS in the provided TRNSYS input
file. The maximum allowable number of constants + equations has been
exceeded. Either reduce the number of equations and constants in the
input file or increase the limit on the number of equations and
constants. If the limit is to be increased, the variable nMaxEquations
should be modified in the TrnsysConstants file. The TRNSYS source code
will then have to be re-compiled and a new TRNSYS dynamic link librairy
created."
I cannot reduce the number of equations and constants otherwise my
model is false. How can i re-compiled my TRNSYS source code and is
there any risk in doing that ? Furthermore, where can i find the
Trnsysconstants file ?
Thanks for your answer.
Best Regards.
Frédéry.

Subject: [TRNSYS-users] Runtime error using Type155 Matlab Calling
Dear all,
I wrote some some small
programs in matlab using .m files. I then coupled these .m files with
Trnsys16 Studio using the type155 component. They work fine
individually, but when i try to make them comunicate, linking outputs
from one of them to inputs of another one, i receive this error message:
"Runtime error!
Program: C:\Program
Files\Trnsys16\Exe\TRNExe.exe
This application has
requested the Runtime to terminate it in an unusual way."
On the other end,
liniking the Type155 with a different component, as the weather data
reading and processing Type109, doesn't give me the same problem.
Can anyone help me to solve
this problem?
Thank a lot in advance
Best regards
Giacomo

Giorgos,
I would stay with Type753 (heating coil) and Type508 (cooling coil)
if indeed that is how the building is being heated and cooled. I am not
sure how you are controlling the system but I would recommend putting
the zones into temperature level control and adding a thermostat that
turns on and off the flow to each coil depending on the temperature of
the zone (instead of calculating a zone load and then somehow imposing
that on the coils. You may also need to use some diverting valves
(Type11) to control whether the water from your heat pump is going to
the heating or the cooling coil.
Kind regards,
David

Dear all
I am new user in trnsys and I
try to
simulate o ground source heat pump system connected to o 7 zone
building (type
56), in order to study the interrelation between ground, HP (water to
water), fan coil and building.
My question is what type of
fan coil I must
used in order to meet the heating and cooling demand?
Until now I tried to solve
this
problem by using type 753 and 508 simultaneously, but it is difficult
to controlled
it!
Is the right way to use of
water to air
heat pump (type 505), as fan coil or you have any other idea about
this
problem ?
