[TRNSYS-users] Simulation of solar cooling system with solar collectors mounted on external wall

Chun Kwong,
If you have solar collectors that are truly integrated with the facade
of your building then you will need to define the building wall on which
the collectors are mounted as a BOUNDARY wall with a user defined
outside surface temperature and you will need to define a Type56 output
for either the inside surface temperature or for the energy transfered
out through the outside surface of that wall (QCOMO); which output you
need depends on your collector model. You then need a collector model
that takes either the energy conducted through its back side or the
inside surface temp of the wall and which calculates the temperature of
the interface between the wall and the collector. I believe that there
are some models like that in the TESS Green Building Library.
Kind regards,
david
