I think the best way to cool the hot air is with an a/c coil and a fan to cool it inside the frig, you just need to take care not to drill holes in frig refrigeration tubing or electrical wiring on your frig.

Heat transfer will take place from hot air flowing through the coil, from coil to water and then being removed from water to inside of frig and so on, but will only work to a degree, water will heat up and stop the cooling proccess, you could use ice to supplement cooling, but again this will only work to some degree. air compressor, a hair dryer with a water bottle, manual hand or foot pumps, a large bag, or manually blowing up. This is just an example I found on the internet. Most of you guys will be running compressors not much beyond volume needed to run your plasma cutters. Just thinking out loud here.because I need to address the same issue one of these days.Ī/C coils most of the time are tested at 300 psi, just a coil of copper tubing will hold the pressure you have, what you could do is, make a tank to fit inside your frig, that a coil of copper tubing will fit into and will hold water. Another easy way to dry the air is just running piping with some drop legs. When you weren't using air, the fridge could continue churning away to reduce the temperature of the water reservoir, and then when you needed air again, you would have a 'reservoir' of cooling capacity built up in the cold liquid. The bucket of liquid could also serve as a heat sink or 'shock absorber' to help the fridge 'catch up' with the compressor when you weren't using air, and vice-versa. (I would put the compressed-air coil below the evaporator coil, so that the convection of the warm water coming off the hot coil would help circulate the water into the cold coil.) I wonder whether you could somehow modify the small fridge so that the evaporator coil in the fridge and the compressed air coil that you want to remove heat from were in more intimate contact with something that would make heat transfer between the two coils faster.maybe put a large bucket of water or anti-freeze into the fridge, and submerge both the evaporator coil and the compressed-air coil into that liquid.
