Ice box air conditioner

Step 3 Enjoy

Fill the container with ice. Or ice cream, if you like that vanilla aroma in the air :)

The temperature transfer happens at the surface of the ice, so the more surface, the colder the air will get. Ice cubes makes really great cold air, but melt fast. A solid block of ice doesn't get you that cool air, but can last for hours.

Hope this can save your summer too!

construction of vent isnt necessary. cut a slit and tilt upward. also instead of ice you must replace use ice packs or capped plastic bottles of ice. modern ice packs stay frozen much longer than water. will work much better than a solid block because more frozen surface is exposed. i knew a guy who would do this and pour rock salt over the ice. i dont know how much cooler that would make the air but i would think it would be a bit cooler.

Adding salt to the water will make the ice taking longer to melt. Perhaps it alters the melting point, I guess. And one should try for as larger surface as possible, by putting the ice in smaller bottles rather than in just a big one.
Also, force the air to travel as much over the ice (ice containers, ice cubes) as possible, before letting it come out to the room.
I've just read these in other comments, somewhere here.

Well good instructable! This will be handy for the summer, and yup it looks professional ; ) I'll spray mine silver, to add to to that effect

This is good one! Very simple and im sure very effective... I'm going to make a scaled up version using a box fan and plastic bins and maybe even some cloth that would absorb the water that the iced melted into.. Then it will take advantage of evaporation as well!
