dear Prapapong Vangtook,
QALTL <> 0 during daytime
makes sense, since you operate your active layer during nite time
QCOMI < 0
is the energy from inside surface incl. conv to the air and I-wave
radiation to other surfaces; as long as this surface absorbs heat
-> QCOMI <0 is correct. I assume your
active wall has enough thermal storage. Why shouldn't this make sense?
Hope this helps.
Dear TRNSYS users,
I got some problem about output of a active
layer. A simulation is run by case of running
active layer in night time
and stop in day time.
The results QALTL (total energy input by fluid+gains
of active layers to zone) is zero in
daytime but QCOMI (energy from inside
surface incl, conv to the air and I-wave radiation to
other surfaces) is
still get minus value (-300 kJ/hr). otherwise in night time, QALTL is 1038
kJ/hr and QCOMI is -350 kJ/hr too. It can not possible because on day time
the room air is
vary hot (35 C) and also vary high of solar radiation on
the external wall. Please explain this
