[TRNSYS-users] NTYPE 906: Energy balance for surfaces

[王洋 <wanghongyang1767@gmail.com>]

Dear all,

    I have some questions about NTYPE 906: Energy balance for surfaces:

   1. Please see the ATTACHED.
      
      Based on the Manual, B6_BAL should be always 0, but here i think its calculation is wrong. B6_BAL isn't  -8.180E-13, it should be 2.683E-03, so it's not 0, PLEASE tell me some possible reasons about it. 
     1_B6_BAL  = -   1_B6_DQWALLdt-   1_B6_QCOMI+   1_B6_QCOMO+   1_B6_QRADGI+    1_B6_QRADGO-    1_B6_QALG 

      -8.180E-13     -3.838E+03      2.683E-03     -3.838E+03      0.000E+00      0.000E+00      0.000E+00
2. B6_DQWALLdt in Manual is change of internal energy of surface, but it's a little abstract. Here I only used the heatings in TRNBUILD, no other internal gains. PLEASE give me some examples about change of internal energy of surface. Is it energy Generation of Wall etc.? Why here is  minus (-3.838E+03)? What's difference between  B6_DQWALLdt and B6_QCOMO? Why here they are the same? Is there some reasons?

3. I think B6_QCOMI is some heat flux enter into inside of wall such as the heat from the heatings of indoor and the solar radiation, Is it right?   B6_QCOMO is heat loss from the wall outside, Is it right? If wrong, PLEASE tell me what are their meaning.

Thanks!

Hi,

 

seems like you hit a limit for the generation of the transfer function coefficients.

Please check if the roof is defined correctly.

Betreff: [TRNSYS-users] Strange error

Dear TRNSYS users:

 

I am working on a model created buy TRNSYS 3d plugin in google sketchup for couple of months. Everyday I add  something to it or modify some parameters in it. Today, I have just changed the roof type in the building type 56 and tried to run it again but I have received the following error:

 

 

Visual Fortran run-time error

 

fortrtl:severe(64):input conversion error, unit 56, file C:\.....building.trn 

Image PC Routine Source DFORRT.DLL  02014C49 Unknown  Unknown Unknown

 

 

Anybody has an idea to solve the issue?

 

Thank you.

I`m doing a dynamic simulation of buildings in TRNSYS, during the simulation gave the following error ... as you can see in the picture.

And also, I would like to send me a PDF about connection.

I await your response.

thanks.
