Hi,
I tested calculation the Conduction heat flux from the wall at the outsideside surface (qso) and Conduction heat flux from the wall at the inside
surface (qsi) with the coefficients of transfer given by TRnbuild but I do not
obtain same the results as TRNSYS by comperant them with QCOMI (NTYPE 19) and
QCOMO (NTYPE 19).
is what you can help me? best regards
