Can a home made AC unit be run through a mini fridge? Answered

when making an air conditioning unit, would it be possible to run the system through the inside of a mini-fridge, rather than a bucket of ice? maybe drill some holes and put the system inside, in a little bin of water.


No, the power output of a mini-fridge is a tiny fraction of an AC unit, and even Nfarrow's suggestion has a considerable cooling capacity from his ice supply. A mini-fridge is unlikely to offer even 60 W of effective cooling, and you still have to dump the energy from the hot side like Frollard says.

You could - but you have to remember the cold in the fridge is all the heat being pumped out the back of the fridge - you need to situate the fridge outside, or you just pump the heat around your own house.
