goal

- Will be used to chill water(with additives to lower freezing point, like windshield washer fluid and antifreeze) for a watercooling setup

the parts

- Whirlpool dual loop? i think(it has 4 pipes on it, 2 copper, 2 steel) 1/4 HP compressor never used. Drained lots of fluid out of it(oily).

- Im going to use coils of copper pipe for the condensor and evaporator. Each will be inclosed in PVC pipe, which will be sealed. The pipes of the evaporator/condensor will be routed out through holes in the side(which will be sealed with epoxy). Barbs will also be in place, which will allow water to circulate through it all. This means water will take heat away from the condensor, and water passed over the evaporator will be cooled.

- Water to cool the condensor will be brought cooled by a bong.

- need thick walled tubing with small ID for cap tube

what i need to know.

- Why the F*** are there 2 steel pipes and 2 copper pipes on my compressor? is it a dual loop(one for fridge, one for freezer?)or something else?

- Length of capillary tube and ID

- What refrigerant and how to put it in the system(needed valves etc). I am thinking propane. A pound costs around around $2 here. In addition the valve for my torch head, uses a flare fitting, so it should be easy to connect to copper pipe fo r putting into the loop.

- What oil to use. Putting it in the system should be fairly simple. I just need to know where to get it, and how much to put in, and what kind it needs to be.

- How to prevent refrigerant from stagnating(pooling up) in the loop.

- Do i have to use a vacuum pump? i dont need the absolute lowest tempatures since too low would freeze the liquid im trying to cool.

- How to cycle the compressor to prevent freezing my liquid(and extend the life of the compressor).

thnx...
