Summer is here and thanks to global warming it’s going to be a hot one. Some of you might have a great air conditioning system in your pad. You may even have one with fancy digital controls and the such. A lot of you however don’t, leaving you with nothing to fall back on other than a system of beer, fans and standing in from of the fridge.
However there is hope, with this simple guide you can build your own DIY AC. Oh Science, is there anything you CAN’T do?

this is what i need - i mean, exactly what i need. too poor to purchase ac but too hot to do anything at all between like 10am - 6pm. anyone know how often you'd have to refill the cooler?

Love the A/C idea. Going to have to try that if mine ever breaks down. Good idea =)

Couldn't this lead to legionnaire's disease? I thought that those little bacterial buggers loved to live in ACs of this type. Maybe I'm wrong, I'm not a doctor or an AC engineer! Cheers

Try hooking up a $10 submersible water pump, no gravity needed and you can run the water right back to your cooler :)

There are problems with this method: It wastes water, its temporary, if you drain the water at our foundation that's bad. The comment about using a pump is very good though. Maybe I'll try that sometime.

Okay - Where do you get the ice? If it's from your freezer then you are wasting energy and get no net gain - your freezer cools using a heat pump - so for every piece of ice you pull out of it, it must pump heat into your living space. An AC unit on the other hand pumps all that heat outside. If you get your ice from the store then you must drive there, wasting gas. There is no net gain here. As for the dude who asked about Legionnaire's disease - this one is a closed system - it's not a swamp cooler which drips water onto a substrate and relies on evaporative cooling so no - no legionnaire's disease with this one. Just disease of stupidity, which I suppose is what leads to anyone thinking this is a good idea.

Might I suggest that your local library likely has air conditioning & that anyone who thinks this "air conditioner" is a good idea needs to go hang out at said library until they understand physics a bit better.

for all you physics 'GENIUSES'....this is a primitive way of creating a localized cool zone...ie;...in front of the fan...not purported to be whole house central air...go chill your hard workin brains...they are overheating...oh btw one real problem is condensate that will collect on copper cooling coil...
Better AC

Better way of doing it that is free to chill the water. Using copper tubing dig a shallow ditch and bury it under ground run the vinyl tubing through a window or something too hook up to your home made radiator use an inline pump.

Have you heard of a geothermal heat pump ? It will save you money on your AC system and its even eco-friendly! Lucas http://earthfriendlyconstruction.net

this is silly - it's assuming a constant supply of water being dumped outside? you could get the same effect (albiet slower cooling, but the ice would last longer and you would get more from it) by just leaving the cooler of ice sitting in your room.
