imagine if you will, a cracked up concrete slab. up here, we have permafrost. during the summer the gound out on the land thaws to a depth of approx. 1-2 ft.
in town where we have the water and sewer mains, the ground will thaw to about 1-2 ft below the mains, this is in the heat wave of summer (21 c or 72 f). the land is basically a big frozen sponge. except of course where we apply heat to the ground whether its through the pipes, or a concrete slab.
think about it like a big concrete raft in the swamp, during a heat wave. it gets all cracked up.
somebody came up with the idea of keeping the ground under concrete slabs frozen. even during the heat wave of summer. now the slabs don't crack.
horizontal steel pipe is laid in the ground prior to pouring the slab. i'm not sure how the pipes are connected together to the cooling towers or what the btu cap. are. is for liquid carbon dioxide, but it must be dam cold, eh.
cooler than the drool on a polor bear's tool.
upon near completion of the building being constructed, the cooling towers are installed.
the cooling tower is a vertical steel pipe with a bunch of steel fins. kinda looks like a bull rush on steroids.
the vertical and the horizontal are connected together. the horizontal is then fill with liquid CO2, then its sealed up.
the idea is: the liquid CO2 absorbs the heat. it turns into a gas and travels up to the cooling tower whereby it releases the heat, forms back into a drop of liquid CO2, then travels back down the tower back to the horizontal pipe!
almost sounds like a perpetual motion machine.
i heard this once: within every problem, lies it's own solution.
one of the big train company's up here called VIA, i'm sure you heard of them also uses the "thermal syphon". they have a line that runs up to churchill, manitoba. that's the end of the world for most people except us of course.
northern manitoba is also a big swamp and i guess they have had problems in the past with the rail line and and the "big sponge".
they installed thermal syphons under the problem areas of the line, no more problem.
hey jc, if a person lived in a really hot area, would nitrogen be better instead of CO2?
but to work the air temperature has to be below the ground temps is that correct?
