Hi indika – Running a loop of liquid nitrogen might be possible but would be rather impractical in my opinion. Pumping will be near impossible with retail parts, and the liquid nitrogen will quickly boil off unless you create some sort of pressurized loop – at which point you’ve almost made a real air conditioner!

You might be able to pour a small amount into a gravity fed tube that the fan then blows over, but it would be more of a “one shot deal” if you will and more useful for a demo rather than practical use.

It’s possible, but if done in the manner you describe, would actually lead to the room heating up due to inefficiencies of the fridge!

A fridge does not magically make cold, it pumps heat away from it’s interior insulated chamber – so the heat must go somewhere. That’s why the back of your fridge is always nice and toasty.

You could possibly modify it heavily so that the heat could be pumped outside via a window (like an air conditioner) but unless you’re familiar with working with pressurized gases it will likely be rather dangerous.

I was wondering about this….

If a old fridge or freezer can be found / salvaged, do you think it would be possible to utilise the cooler on these to run a DIY air con?

I was thinking if a small fridge can be burthcered a fan could be incorporated into the frame and the door removed.

Any thoughts on this?

Hi Yoni – the water should be cold (or else it isn’t going to cool much), but how you cool it it up to you. Using ice or a cold water feed appear to be the two primary choices.

Hi.
I don’t sure i understand.
Is there anything that makes the water cold? or that is a thing i should care of by putting ice in it?

Thanks!

Dear Sir .We are lucky to get your design about ice airconditioner in the web,because we are going to use yr idea for our seaside camping site in Galang island, a small island near Singapore but don’t hv electricity. We hope yr idea will be very useful, because
our island is hot, but the the scenery is very beautiful,Thank You

Sincerely Yours
