Modified AC Unit

I was referring to the air flow for the ac, nothing to do with the fridge part of the video.

He's comparing apples to oranges with the dollar store fan. it isn't designed to push air through a heat exchanger, or the louvers in the A/C shroud.

Gordon I know that comment, is suppose to be sarcasm
But it makes no sense
The first part of that video is about creating more air flow, by opening up the rear of the A/C,

The second part is making the fridge work using solid state Peltier cooling units, to have a fridge in his shop
Those Peltier devices are not cheap, although less expensive than a new fridge

No dollar store clip on fans for cooling, is Mention anywhere in the video

I don't see any connection to you comment

So a dollar store clip on fan, and the blower in my air conditioner are the same?
