Any of the existing models would represent a major simplification in
studying this system. My recommendation would be to create a new
component that models the configuration that you are studying; with
TRNSYS 16 the hardest part will be to formulate the governing
equations.  There are also firms out there that can create models
for you based on your specifications (TESS, TRANSSOLAR to name a
few).  Good luck with your project!
