AC

[richard bies <bies@domain.elided>]

Suppose the discussion over suspension tuning peters-out -- we need a new
controversy....

As the AC evaporator cools the stream of air over it, the conventional
wisdom is that really cool air will result only if already cooled air is
recirculated....

HOWEVER

These things have a lot of glass, and it is not at all uncommon that the
air in a parked car will be much hotter than the outside air...

Thus it seems to me that the most rapid cooling will result if outside air
is used until the internal temperature goes below the outside ambient.
(And if it is really hot and sunny, it may never get there, even if
internal air is vented...)
