Re: [TRNSYS-users] TRNSYS-users Digest, Vol 89, Issue 19

Hello Dakhli,

very briefly:
You need a table of operation points from your machine. It must consist of values for - Fraction of design load (=FLOW_CHW(i)*CP_CHW(i)*(TCHW_IN(i)-TCHW_SET(i))/DesignCapacity) 
- Chilled water setpoint
- Entering Chilled Water Temperature
- Inlet Hot Water Temperature
covering the range you want to simulate.
Additionally, you need to calculate the two values for these operation points TRNSYS will receive from the performance map: 
Fraction of rated capacity (=Capacity(i)/DesignCapacity)
Fract. Of Design Energy Input (=Q_Hot_Water(i)*Design_COP/DesignCapacity)
All values with an "(i)" are values specific for that single operation point.
You can have a look at the source code of the type, there it all becomes... clear.
Imho, this type is unessecarly complicated and the map is tricky to set up. Have a look at the documentation and the source code and If you need further assistance, let me know. 

Best regards,
Jochen

hi everybody,

well, i am beginner with trnsys. I tried the example of the EES calling
function but it's not working!
i asked some other people and it's the same for them!! do you have idea
about it ?
otherwise, do you advice me to work with type107 instead of EES ? I need to
make the modeling
of the solar cooling system for a building under Tunisian climate (it's a
Bachelor thesis, so there's a pressure of time)

best regards.

PS: Thank you for clarification Mr. Jochen.

Subject: [TRNSYS-users] run simulation (use new component)
Dear Sirs,

I am a beginner user of TRNSYS so I am not sure if I use it in the right
way. I want to use a new component which I receive but even though I copy
paste the *.dll file of the PCM component to the exe folder of TRNSYS and
the *.tmf to the proformas still have an error which says that " A TYPE was
called in the TRNSYS input file but was either not linked into trndll.dll
or was not found in an external dll. A dummy subroutine was called in its
place. Please link the TYPE or remove it from the input file".
Thank you.

Regards,
Eva

**

The user-created DLL's don't go in the Exe folder.  They go in the correct
spot in the UserLib directory (depends on whether the DLL was created as a
release version DLL or a debug-version DLL).

Dear Dakhli,

type107 is a performance map type, i.e. you have to supply a table with
(steady state) operatingg conditions from which the type takes its current
performance (including interpolation).
When you use a calling function like calling EES, you have your chiller
modelled in a different environment (here the Engineering Equation Solver).
There you can have for example an advanced physical model, which might be
hard or impossible to program in sequential fortran code as used for TRNSYS.

Best regards,
Jochen

Hi everybody,

i read some articles and i found that some people are using type107 in the
modelling of the machine
and some others are using the calling function of EES. So, what's the
difference between them ?

cordially,

Subject: [TRNSYS-users] External data files for heat pump&  absorbtion
chiller
Dear all,

I need to use a water to water ground heat pump (type 668) and absorbtion
chiller in my simulations. It seems to be very difficult to find product
catalogues that include the information required in the external data
files. Could someone with experience please tell me which manufacturers do
provide this kind of information and perhaps send me a link. The only
catalogue data file that I was able to for water to water heat pump was
this one from Carrier:
