loosly.. they are both heat exchangers.

cause i know i could go elaborate setups and stuff and this may be more work but i was thinking in just running cold, icy water through one with a fan to cool the air.
People involved in my last thread about making air cons (hence why i put it in outhouse and not tech) will probably think we finished the conversation but i am lazy and poor and couldn't be stuffed buying or piping or wiring, whatever, a "real" air con system for my house (as i still live at home and prob won't be here much longer)
I was thinking in building a portable system with a foam esky filled with ice a copper or some sort pipe running through it (as i guess it will have to run coolant or the IC will rust) and a small pump to keep cold water flowing through the IC with a small fan (computer maybe) having keeping air flowing through the IC.
The point in this setup is that i will not have to purchase anything as i have it all lying around here now. i could freeze Chinese containers with water to make ice blocks to fill the esky with and keep it cool.

To transfer large amounts of heat (from the air, to cool it down) you need a large temperature differece, or a phase change. the system you mention will not work as well as an evaporative air conditioner for example, but might take the "edge" off the hot air.

i am not wanting to climate control or anything, just make things a little cooler, i am aware that this will not perform as well as a standard system but it will do something, even to leave it in a room for a while to work without anyone in there, or i could stand in the airflow if it gets bad, but yeah i am not wanting crazy results just something little

what you're proposing is how many large building cooling systems work - they chill down water, pipe that down to various floors, then use the cool water to chill air flows.
they obviously do it on a much larger scale and many (like the shitbox thing i work in on George Street) have very cold water and produce such cold air that it has to mixed with outside air to lift it to a non-freezing tempreture.
downside is that you need a lot of cold water - hence the energy bill (or cooling effort) to chill down the water is significant. fwiw, i asked about keeping the air on for a weekend on my floor of a 24story building and was told that they'd need one of two chiller plants running and the bill would be $hundreds. fuck that.
anyway, i digress... if you had a large mass of waterthat you kept cool then using a recirculating might work - but your talking about something the size of hot water system.
The cheapest thing i could thing of would be a large keg(s) of water in a fridge that feeds a radiator infront of a fan - circulate the water from the radiator to/from the keg. The larger the volume of water in the fridge, the better. You could use a cheap garden waterfall pump to circulate the water.

well i have a petier (i think thats how its spelt, those thermalcoupler things) esky i built. but that pulls 10A at 12V and needs to be left on so it draws a bit of power. i reckon a bit of ice should do the trick ok, then if need be i can go more dramatic when its needed.
I though thats how air cons sorta work, cept they use gas not water.

peltier...
i made a fridge out of an esky.
trust me these things arent that great.. it takes the chill and a little more off room temp in the esky... i havent done full testing as the old man doesnt trust it in the house.
here it is.
the unit - not exactly small or efficent but needs more testing.
the bottom of the peltier and the fan to get the air moving.
massive heat sink too cool the negative side of the peltier.
the bridge rectifier - used to converted power to dc i think. the system was meant to run from a 12v dc power from sig lighter in car. but had to make this to convert the barstard.
the power supply i used to run the thing - its a tad over kill but works well.
all this cost me around $60 if i remember right. and i made this as a school project in yr 11 a year ago.
peltiers are a waste of time unless you get a decent sized one.
there only good to cool computers down.

that's a cool cooler dude...guess it can save you trips to the fridge to fetch some beer, if ya put the cans in there.

yeah theres imperfections as the peltier setup was meant to be for cooling water in a polistirine container. i modded and adjusted it to fit to the cooler. if i want it to work properly ill change it.
"ndgcpr" hope this helps you out with some of your things.

what you could think about doing is getting and old intercooler and plugging one end and filling it with urea fertilizer and water. presto, an endothermic reaction that will absorb a decent amount of heat.
then all you need to do is strap the IC to the front of your pedestil fan.
though, expect ASIO to roll up at your doorstep after you go to your local ag shop and buy 50kg of urea

Read the whole thing michael. i don't want to stuff around installing stuff in walls and whatever else is involved in adding actual air con as i don't intend to stay here much longer.
Anyway pics of my peltier efforts, i used foam eskies cause its easyer to work with and you get them free from the local store, just ask for a "broccoli esky".
Anyway it uses 2 4 amp peltiers (thus the large load it presents on a transformer) and a aluminum "skeleton" to transfer the cool, it take about an hour to cool the metal but then it should be ok, i haven't really had a big enough trans to test it properly, but i ran it driving to the coast, an it was just getting cool when i got there 
The side (this is on both sides.)
And the inside to move the cool around, it also lets you fill the bottom with some water to help transfer.
