[Bldg-sim] thermal labyrinth/passive air cooling

[Peter Alspach]

check the archives for this list - this has come up before. I believe
there might be a TRNSYS model for these?

Subject: [Bldg-sim] thermal labyrinth/passive air cooling

Apologies for cross posting, however I wonder if someone here can help
me:

I'm investigating the potential for thermal labyrinth cooling in a
desert climate such as New Mexico.  Although I haven't looked in detail
at the weather data, I imagine the diurnal range would be sufficient to
provide cool enough night air to dissipate the heat accumulated within
the mass of the labyrinth walls during the day.  At least that's the
idea.  I'm not sure about the best way to prove the effectiveness - does
anyone have experience of design and modelling such a system?  It would
be great if you could give me any suggestion or pointers to further
information and/or design guidance.

In addition I wonder if there are any existing buildings you know of
that utilise such a technique.  It would be great if I could find some
case studies demonstrating successful application of thermal labyrinths
for passive pre-cooling of supply air in hot/desert climates.

Thanks for your help,

Nick
