[AT] OOOPS - Do as I say not as I do - now rambling off topic

[Larry D. Goss]

Is there a large commercial building constructed anywhere today that
doesn't have an energy recovery drum incorporated in the air handler?
That's a similar concept to what you're talking about, Charlie.  

Come to think about it, I worked in a modern building in West Virginia
that didn't have a central air handler.  It had around 50 three-phase
heat pumps mounted in the plenums.  One day a squirrel chewed through
some insulation, shorted out one leg of the power, and about half of the
motors locked up before we could get the HVAC systems shut down.  The
telltale stench of burned varnish off the motor windings stayed in the
building for weeks.

I have toyed with the idea of placing a long coil of plastic pipe in a
coil 
about 10 feet in the ground with insulated and filtered air shafts
coming to 
the surface from each end of the coil.  Then using some sort of air to
air 
heat exchanger.  That is just a thought at this point.  I haven't tried
to 
actually figure it out.

I actually like oil heat.  Fuel is getting fairly pricey there is always

fuel oil available in one form or another even if you have to buy diesel

fuel with the road tax on it.  The new high efficiency oil furnaces (and
gas 
too for that matter) have a very high conversion rate and some of them
even 
to the point that they use pvc pipe for an exhaust stack.  They can be
run 
on a small generator in the case of power outages.

By the way Spencer seems to have a 15k limit on messages these days so
we 
need to start cropping off the previous messages some.

Funny thing is that I never saw the first and part of the second
sentence of 
Roger's message until I read it in Al's reply.  Somehow it was cut out
when 
it came to me from the list.  I figured it out but I had to read
..before... 
the lines.  grins.
