First my Logic
When the Sun is out, that is when the largest quantity of air conditioning is nessisary. (in california, texas , etc)
so
if a solar system that was supplimental (verses grid tie) was able to run some sort of air conditioning, it would be a way to use the power, without the need for batteries as much.
Discount all Swamp coolers for this discussion, swamp cooler is not an option, due to increased humidity, mold mildew, and etc etc . they are highly efficient, and excelent naturality to them (water earth etc).
air conditioning is a very high power consumption device, and impractical for smaller solar systems to try and run say a compressor.
but the compressor on high tonnage devices doesnt nessisarily run the entire time.
i could run a smaller air conditioner
i could run a small refrigerator, and have the coils outside
i could create a huge propane fridge using solar concentrators (see idea i had at half baked)
or
i could run a weird peltier cooling wall.
and that is what i chose to test, because i can test it in the SMALL
the disadvantages of peltier, low efficiency, slow operation
if i look at the low efficiency of it, i also have to analize the low efficiency of a Motor, the compressor system, power generation, and line loss via the power company. so mabey adding all that in the compressor systems might not be so hot after all. even if they ARE hot :-)
the peltier ends up pumping 2x as much heat as it draws out
heat exchange with it is 3MM from eachother, unlike with the pipes that can be used in a compressor system to move the exchange further from its source.
the compressors are either whole house, a waste if your not IN the whole house, or much lower efficiency window models. even a window model can use 1500+Watts, and only need to run in cycles.
a peltier system could run as a constant, as soon as the sun to operate it came out.
even though the AC is not needed as much till later in the afternoon.
so i am testing SMALL, very very small, then if the tests have any usefull validity, i would try that larger. but i am thinking both small and large at the same time :-( how different it would be at large.
if a house was built with a heatsync WALLs in it, so to speak, it could be designed as a 100% PASSIVE heat pump system. have enough heatsink, and a LOW enough flow of heat exchange, and there would not NEED to be fans. Fans are still practical at .9a for a fan, to motivate 9A of exchange, but they still add noise and power consumption.
so a slow running, totally passive peltier exchange system. got it?
Now with the QUESTION.
is chimmney convection so effective that a OPEN to the air passive heat sync would be cooled more when its in a verticle tunnel?
assume that there is NO wind, just the convection from the heat of JUST the heatsink.
if i put a chimney around a heat sync and its in a computer, that is great, it moves it OUT of the computer, but in this case, the heat is already outside so to speak, and i would just want to increase the passing of heat to the outside.
by Blocking the thing into a chimmney i am reducing exposure , possibly HEATING it instead. but if convection (heat rising) is so almighty powerfull, would it be possible to enclose or block flow, and actually INCREASE it through convection.
