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!
