Using Freon?

Captain Helghas · 03-10-06, 01:29 PM

I found a source of Freon. Not the new stuff we put in cars which is supposed to be environmentally friendly, no I mean 1970s "Screw the Aquafer" Freon. Would this be worthwhile in a WC setup? What kind of modifications or hazard management do you suppose would be necessary?

If you used freon, you'd be in extreme cooling.

You couldn't use freon in anything that even slightly resembled a standard water-cooling loop. Freon is used in a phase/change system such as an air-conditioner, water-cooler or fridge. The systems are so completely different that you wouldn't likely use 'any' component from a WC loop in a phase-change system... besides axial fans... on the condensor... I guess... shrug.

The point is... it's a TOTALLY different world. Freon cools in a pressure environment. Water-cooling loops are (relatively speaking) pressure-free. If you wanted to design a freon-based P/C system, awesome. Go for it. The extreme cooling guys will be a much better help than we water-cooling guys... I don't even know if freon is a commonly used coolant in our market. I have no idea.

From what I understand, using Mercury would be even more (*screams) EXXTREEEEMMME, lol.

Mecury would just be like water, but with mecury instead, and ignoring the fact that it'd kill your pump and probably corrode, it wouldn't work as well. You could boast that a leak would requre hazmat thought

Freon is the best for PhaseChange coolers... ecpecially the old stuff.

Thanks guys. You probably saved me a month of heartache.

I do believe refridgerant (freon) is a gas at room temp and greater. The way it works in a refridgeration system is that it is compressed. As a result of the high pressure, the gas turns into a liquid, and also cools down. When the cold liquid is warmed back up, it returns to gas form, and the cycle goes on. Refridgerant isn't a magically cold substance, it is just engineered to have the appropriate boiling/condensing properties for use in refridgeration systems.

Actually, it warms up when compressed. The bulk of this warming happens as it changes to liquid and the heat that was keeping the molecules in a gaseous state goes to raise the temperature. This produces temperatures well over ambient and aids heat transfer to the air.

When the liquid depressurizes, it boils and turns back to a gas. It takes quite a bit of heat to change a liquid at its boiling point to a gas at the same temperature. All this heat has to come from the refrigerant itself, and because it has no more heat as a gas than it did as a liquid, the temperature drops drastically.

But yes, Freon is definitely a gas at room temperature and pressure.

You'd be better off if you could use N2 from a university tank. It should require much less pressure to keep as a liquid at room temp. If I remember correctly those tanks were ~25-30 psi.
