Ok, now i understand the concept abit.

But should i put the copper tubing at the front or the back or both ? which is better choice ?

What if i juz circulate the water without the ice, usually it will produce what temperature?

If with ice, whats the standard temperature it can reach?

[...] a DIY air conditioning system. For a less complicated version, just stick a bowl of ice in front of a fan so the ice cools [...]

This is quite common in India. http://www.nahataelectricals.com/pcat-gifs/products-small/air-cooler-cyclone2.jpg
You just fill the bin with water and u get the room cooled in no time.

What the hell do you need an air conditioner for up in Canadia, eh?

Of course – which is why when I used this I slept in my bedroom, not in the kitchen next to the fridge. This is a heat pump, and where you pump heat from and where you pump it to are up to you!

You do know the heat generated by your fridge to make the ice is the same as the cool you get out of the ice right?

If I were to try and use an old fridge as an AC I would put the fridge outside and use some flexible insulated ductwork to circulate air in/out of the fridge. What I would say is that if you hit some yard sales or craigslist you can pick up a window unit for about as much as the junk you are going to use trying to make one of these contraptions

Hi Billy – The most efficient way to construct this would be to use a radiator/heater core or similar. Copper tubing works, but only transfers a fraction of the heat. If you look around at surplus stores or similar you can find a radiator for less than the price of copper tubing.

Geoff,
So, I made it and it kind of blows cool air. It’s not the best construction. Maybe that’s the problem. You can see pictures of it here: http://www.billyhollis.blogspot.com

I’m wondering if a swamp cooler would work better? If not, I’ll stick to this and re-work it until it’s right.
