[TRNSYS-users] parametric table with type 56

[Diego A. Arias]

Dear Christophe:

The energy balance on a zone is given by:
BAL_ENERGY = -DQAIRdt + QHEAT - QCOOL + QINF + QVENT + QCOUP + QTRANS + 
QGINT + QWGAIN + QSOLGAIN
BAL_ENERGY should be always 0.

You can get many of these values using the optional outputs (NTYPES):
DQAIRdt --> DQAIR (NTYPE8)
QHEAT --> QHEAT (NTYPE30)
QCOOL--> QCOOL (NTYPE31)
QINF   --> QINF (NTYPE4)
QVENT --> QVENT (NTYPE5)
QCOUP --> QCOUP(NTYPE6)
QGINT -->  QGCONV(NTYPE7) + QGRAD(NTYPE13)
QWGAIN --> QTWG (NTYPE76)
QSOLGAIN --> QTABSI (NTYPE14) + QTABSO(NTYPE15)

The only variable that is not given as an optional output is QTRANS. 
But, as you have all of the other variables, it can be calculated from 
the energy balance.
Please let me know if this helps.
Best regards,

Diego
