Well I was bored out of my skull and for some reason house cleaning wasn't going to cut it, So I figured I'd finish a project that I had procrastinated away for dam well 5 years! (Ya I'm a pro at putting things off)
So a brief over view: The main reason I decided to build one was to re-use old R-12 from fridges as there are plenty about, but my conscious killed that Idea I just can't murder our environment like that by allowing the gas to be put into another system, I'll let the HVAC guys take it to be destroyed (Thats what we do in BC any old R-12 is incinerated and destroyed) how ever during a recent move the guys killed my chiller, and I been getting more R-22 charged systems. With my chiller damaged and scoring some Ac's I figured about time to make a system to both recover it and mediocrey recondition it by removing oil and other such things from it.
The design concept: By using an old green propane tank as the intake separater it leaves plenty of space for it to suck in liquid, and any who do home brewing knows the idea of distillation it works the same for refrigerant! We boil the refrigerant off leaving the waste oil inside the tank to be disposed of. Using an oil sep on the compressors discharge we can prevent the compressor oil from getting back into the refrigerant being recovered, and by using a cap the refrigerant being recovered will all so cool the compressor!
So after recovering the refrigerant, I set it up so it sucks in liquid, distills it, then puts it back in the tank in a continuous cycle, Oh with a F/D in-between the tank and machine of course on the suction side.
Now for the picies!
