Re: [VAC] Dry Ice Air Conditioning

["Dr. Gerald N. Johnson" <geraldj@xxxxxxxx>]

I suspect its nothing more than a container to hold dry ice (solid
carbon dioxide, very cold) and to vent the CO2 to the outdoors while
letting interior air pass by the container and be chilled. It might be
just small pieces of dry ice in the living area, but one has to vent
carefully to keep from running out of oxygen for breathing.

I kept a chunk of dry ice in my mom's refrigerator overnight while I was
in high school to have it for a snow making experiment and it froze
practically everything in the refrigerator, even the eggs. Just a couple
pounds of dry ice did that.
