[TRNSYS-users] How to best model zones in zones?

   We have dealt with some similar cases where there is a large 
refrigerated box in the middle of a much larger zone. We simply define 
two zones with the walls of the refrigerated box enclosure being set as 
ADJACENT walls that separate the enclosure space from the larger zone 
volume. This means that you cannot do the detailed radiation exchange 
model in the larger zone (since it is no longer convex).
Kind regards,
