So if I wanted to recycle an old refrigerator to turn into a chilling solution for 30 gallons of glycol, what would I do? First off I don't want to stick a tank of glycol inside the refrigerator. I'd rather construct a copper coil evaporater that is submerged directly I to the glycol. The tank building isn't so rough, neither is the march pump to circulate glycol, nor the pid and electric wiring. It's really understanding the refrigerant line and how to remove/ fill it with freon. But I don't know whAT to do to salvage parts off of the fridge.
First I'd imagine that I'd have to install a T-valve fitting into the refrigerant line to recover the freon. But how? Then I'd like to sever the refrigerant line, run 20 feet of copper line through bulkhead fittings into my tank( 20 feet? Or how would I calculate the length of the evaporator) and reattach, vacate air out of the lines, add refrigerant (to who knows what pressure), voilà! So i'm needing some help. Thanks for any replies!
