They do, at least below 31C. Above that it's supercritical CO2. Cheap
paintball tanks are all liquid CO2, and valves and hardware are easy to
get IIRC. The critical pressure is around 75 PSI, so it's pretty easy
to handle.

Where was Phil all this time anyway ?

He sounds kind of like Trump in his attitude of knowing everything
about all things audio.

Why not ?

Don't top post.

Phil doesn't sound in the least like Trump, not least because he comes pretty close to actually knowing everything about a lot of audio stuff - he doesn't say much about digital audio, so "all things audio" isn't entirely fair.

Trump's problem is that he hasn't got the attention span to sit through briefings that are long enough to tell him as much as he needs to know, which - combined with excessive self-belief - encourages him to get on with doing something, when that something is frequently ill-advised (because he wouldn't sit still long enough to absorb proper advice).

The CO2 triple point of CO2 is at 5 atm and -57 C.

You need at least 50 atm to have liquid CO2 at room temperatures.



CO2 tanks used by welders are 5000 Lb test tanks typically filled
to 3000 psi. That is 204 atmospheres.

CO2 is not used for cooling because it is a deadly gas that has no
stink indicators put into it like the flammables have...

Your ignorance knows no bounds. The atmosphere is 0.04% CO2. If it were a deadly gas we would already be dead. If it is in high proportions, high enough to reduce the O2 concentration from the normal ~20%, then it might have impacts. The same could be said for literally ANY gas.

You are likely confusing CO2 with CO which is a deadly poison. You can even be alive and breathing but if you have absorbed enough CO into your system there is nothing that can be done to remove it and you will die essentially from lack of O2. The CO has a much higher affinity for O2 and won't let it go, so you breath in as much O2 as you want and it never reaches your cells.

nitrous too because they can't be letting any of us having any fun.
There are no high pressure sealed heat pipe configurations that I
know of. Everything uses media that has low RVP and low boil point.

I liked water systems because by the time I tried it, all the years
of letting the users pipe things up were pretty messy. Now, it is a
sealed system and very easy to add making my machine quieter and
cooler at the same time. Can't mod my laptop though. I am certain
it uses heat pipe technology. I wish they made a door on the bottom
so I could blow the dust out of it in the right direction. Does not
run hot though despite being a Xeon and Quadro graphics. Of course I
need to tax it more to really test that now that I have had it a
while. I hate dust.

As I said, one of my PPoEs had a commercial environmental testing
chamber that used electric heat and open-cycle liquid CO2 cooling. It
worked fine. The amount of CO2 required was trivial.

Idiot. It is deadly. It displaces oxygen. Try taking a nice deep

the body’s breathing control system runs on the CO2 level in the lungs
so if there's increase the CO2 level it'll make you breathe harder

breathing pure CO2 will probably feel like you just held your breath
for 2 minutes

obviously if the oxygen level is low enough breathing harder won't help

Better yet close yourself

twenty minutes with you in the garage with it. That should

your relatives... because you'll be dead.

car exhaust kills you with the much more dangerous CO


.04% is NOT a 'deadly' concentration 'level'.


it is for CO

A car with a working catalytic converter and oxygen sensor, and no
exhaust leaks, doesn't produce much CO. Pre-1974 cars were much more
dangerous.

That's what I said. EVERY gas is capable of displacing oxygen. Literally EVERY GAS!!! That doesn't make it a deadly poison.

Looks like you are not capable of learning. Rather than trying to understand that you don't know something, you have to hurl insults at those who explain your mistakes.

Whatever. It's very clear to everyone, literally everyone here. You are the only person who fails to see when you are wrong.

proportions, high enough to reduce the O2 concentration from the normal ~20%, then it might have impacts. The same could be said

As I read it, CO2 can begin to show long-term toxic effects at
concentrations of as low as .5%, with short-term toxicity up in the
few-percent range. Up in the 7-10% range there's apparently a real
risk of suffocation and death even if there's adequate oxygen. It
_is_ a chemically and physiologically-active gas, so its effect on us
is more than just that of oxygen-exclusion (as you might get with
nitrogen or argon).

It's nowhere near as toxic as carbon monoxide, of course, but not as
safe as a non-reactive gas.

As to why it's not used more as a coolant... I suspect that the higher
pressures required to liquify it (as compared to the halogen-based
refrigerants commonly used) may play a part in that.

It is the CO2, becasue the CO2 is what causes the reduction of oxygen
in the combustion process that causes the rise in CO.

I know more about it tahn you do, chump.

Just as I thought, you are almost as much of a presumptuous putz as

Oh, it's toxic, all right, at about 4% (it acidifies the blood); except for Apollo 13, there's not a lot of
dangerous situations. One can use ventilation to cope with the minor annoyance.

Even oxygen is toxic, at 100%. The dose makes it toxic.

the fluorocarbon based coolants were far easier to work with. Remember
when they used dangerous ammonia as a coolant. It works very well.
Another good one is propane or butane, but BOTH are a no-go for obvious

ammonia is still used in big industrial refrigeration, here most if not
all new refrigerators and freezers use propane (R290)

Using a substance that is a gas at room temp is not a good choice IMO
