[TRNSYS-users] Changing properties of air in a single room?

[David Bradley]

Alasdair,
  I would recommend using an actual tank model; there are three 
vertically cylindrical tank models in the TRNSYS standard library, one 
of which allows the volume of liquid in the tank to vary with time. 
There are horizontally and vertically cylindrical, spherical, and 
rectangular models in the TESS Library. It is a bit harder to deal with 
open tanks; the best bet there might be to look at using the Transsolar 
pool model although it neglects energy loss from the sides of the pool.
regards,
  david
