I would recommend that you send your project to your TRNSYS distributor for direct assistance. You have set your infiltration rates in TRNBuild as constant values (independent of windspeed and direction) for all three of your zones. However, your simulation couples the Type56 thermal model with TRNFlow. In most circumstances, TRNFlow would calculate the infiltration rate and it may be that the constant values that you are specifying (and then switching off) are actually being ignored because of the TRNFlow integration. I am afraid I do not have TRNFlow installed so I cannot check.

Dear all,
I got the result of QINF which are the same when the infiltration is on or off. I think TNRSYS's results are questionable. Why I turn off the infiltration, is there still having QINF?
And when the walls are massless or massive, the result of QINF which are the same, it's 190.73 kJ all the time not only turning on the infiltration but also turning off it; not only massless but also massive.
Please see the ATTACHED and explain them! Thanks! These programs are turning on the INFILTRATION, you can turn off the INFILTRATION. The both results of TYPE 46 linking to QINF are 190.73 kJ one day.
But I calculated QINF one day by hand, the result is more than 190.73 kJ. Q=CairM(Tindoor-Toutdoor)=1.004*( 52*24*1.2)*(20-10)=14976 kJ, where Cair=1.004 kJ/kgK, M=V*Dair=52 m3/h*24h*1.2 kg/m3
I think my calculation is right. I think TNRSYS's results are questionable.
Many thanks!

Subject: Re: [TRNSYS-users] Collectors in Series
Fernando,
You are correct on the flowrates - the collectors in series need to be
scaled down accordingly. I just did a simple simulation with two in series
using Type1 and compared it to 1 with the same total area in parallel and
got nominal results (greater outlet temperatures in series, the useful
energy gain is very similar, yet slightly greater losses in series). I can
send you the project upon your request.
Best regards,
Matt Duffy

Subject:[TRNSYS-users] Collectors in Series
Thanks Matt, hello Felix
I'm still doing some proving. Maybe we should just change the flow rate
"manually".For two collectors in series it would be the same as for just
one, in
this case is clear that we are getting another results.
100 m2 in parallel, flow rate 10000 l/h
25m2+25m2+25m2+25m2 flow rate 2500 l/h
Mit freundlichen Grüßen

Subject: [TRNSYS-users] 64 Bit Fortran Compiler and Multi-Thread CPU's
Does anyone have experience with a 64 Bit Fortran Compiler? I have installed Compaq Visual Fortran Professional Edition for Win 32 x86 Systems V6.6. It is not stable on the three 64 bit systems I have installed it on. I must attempt to load the program multiple times. Usually when I load the program it instantly quits. I would like to take advantage of my 64 bit system and recompile TRNSYS with a 64 Bit compiler. On the TESS website and in the forums there is a brief note on this subject. However the link that is provided to an Intel site with a 64 bit compiler is broken. I have googled 654 bit compliers with little success. I have very limited experience with Fortran, so I may not be using the best search terms.
Also I am running a second generation I7 Quad core with two threads per core. When I run a simulation in the Studio only one thread per core is being used. Is there a way to set the Studio to run on all 8 threads? I set the priority to High (Real Time Setting Could not be Applied), and I set the affinity to all 8 threads. Thanks!

Subject: Re: [TRNSYS-users] TESS library examples two types couldn't run
Dear Chelsea,
You are going to need to determine what the types are errors are that you are receiving when you try to run the simulation, or elaborate on why they cannot run. When you run your *.tpf simulation, there are a few files that are created: the deck file (*.dck, the TRNSYS input file), the log file (*.log), and the listing file (*.lst). The log and the listing file should have the information about your errors. Or, there is an icon on the lower left side of the Simulation Studio, called the "Result File"; you may also click on that to access the log information.
I would recommend upgrading to TRNSYS v17 and TESS Libraries 17 as there are many new, useful additions including the slab-on-grade component with the Google Sketchup plugin, new radiant slab models, and the basement model as well.
Best regards,
Matt Duffy

Hello, Matt:
Thank you for your reply.
But currently I'm using the TRNSYS version16.01.0003. I tried Type 705 and Type 712 in my computer, and also in another computer which is also same TRNSYS version and Windows 7, both of them couldn't run, and Type 705.lst file even doesn't exist.
So do you think this is the TESS version problem, do I need to update the TESS library?
Thank you,
Chelsea

Dear Chelsea,
I was able to run those without any problems in TRNSYS 16.1. Please check the listing (*.lst) or log (*.log) file for more information about your errors.
Those components are from the previous TESS Libraries 2.x. I strongly suggest contacting your local TRNSYS distributor to obtain the upgrade to TESS Libraries 17.01 and TRNSYS 17.00.0019.
Best regards,
Matt Duffy

Could you please try TESS models/studio projects/ground coupling library/Type 705 and Type 712?
They are radiant slab with embedded pipes.
These two examples can not run in my computer, and my computer has Windows 7.
Thank you,

Subject: [TRNSYS-users] TRNFLOW'S large openig and Ventilation in TRNBUILD
Dear all,
I have a queation about TRNFLOW'S large openig and Ventilation in TRNBUILD:
If I defined TRNFLOW'S large openig and Ventilation in TRNBUILD,
How can both of them work? Can they both have influences on each other? What does the QVENT include? Only Ventilation in TRNBUILD or both of them? What does the FLVSZ include? Only TRNFLOW'S large openig's Ventilation?
Many thanks!

Hello,
when I add a wall I have to specify the layers that make up the wall, and for each new layer Trnsys requires three quantities: conductivity, capacity and density.
Now, the capacity is expressed in KJ/(Kg K), but for the layers of wall I have the thermal conductivity (expressed in W/m²·K) instead of the capacity as required by the program.
There is a way to correlate this two quantities so that I can enter the thermal conductivity instead of the capacity?
Thanks in advance

Subject: [TRNSYS-users] Type 15-2_Simulation start time
Dear Trnsys users,
I am using Type 15-2 and i am using a simulation timestep of 3 min. If the
simulation start time is 0 hr, everything works out fine. But once i change
the simulation starttime to 2000 hours i get the following error
massage_"unable to correctly read from the supplied data file-please check
the file and re-run the simulation". This massage refers to Type 15-2.
If I then change the simulation time step to 1 hour and re run the
simulation, no error occurs.
So what can I do to if I want a simulation time step within the range of 1-5
min?
Many thanks in advance
Felix

As usual, TRNSYS users’ day wants to be a space for sharing experiences in the use of our tool where to explain, ask and exchange ideas, works, what to do and what not to. This time two different things will be introduced. First of all, the presentation of new version of TRNSYS, 17th, with its main new features, especially it’s Sketch up plug-in, with a demo. And, also new, the idea of having a technologically focused workshop: we ask you to present your works on
solar thermal coupled with DHC, heat pumps and/or seasonal storage,
and also DHC and seasonal storage by itself.
The aim is to have a technical meeting focused on systems simulation useful for the 44th and 45th IEA Tasks work that will have their meeting in Barcelona the same weeks. We hope this effort will be useful for all.
