Re: Doors
Eduardo,
Can anyone suggest me which is the best way to model an "INTERZONE" DOOR
in trnsys: 1) user-defined adjacent wall - made of wood, for example; or
2) user-defined window - again, made of wood, etc...
In most cases, the solar radiation transmitted through a door (because
it has a window or because it's open) can be safely neglected, so I have
seen many users choosing to model doors as adjacent walls.
If you want to take into account the solar radiation transmitted through
that window, you have to use an adjacent window. This will also allow
you to model a door that is sometimes open (the Window ID in Type 56 can
be a time-varying input). But the window model in Type 56 does not have
any thermal mass.
So I think that you have to ask yourself: "do I want to keep the thermal
mass of the door, or do I want to take into account some transmitted
solar radiation?". And I would think that in most cases your choice will
hardly have an effect on the simulation.
Kind regards,
Michaël Kummert
PS: Note that in both cases you have to define the airflow across the
door using "COUPLING" mass flowrates calculated outside Type 56. Even if
you use the "open window" included in the German window library, Type 56
does not calculate any airflow internally.
