New cooling idea?

[Zebadiah]

Hi guys! First off, I've only got a general idea of how this works...I was thinking of how extreme it is to go with refrigerant cooling because there is alot of extra stuff to keep the condensation off your components. So here is some questions,

 

Does the pressure of the gas affect the temperature? If so, can regulating the pressure increase or decrease the temperature by a good margin? 

 

Does the type of gas affect the temperature very much? 

 

Could you do a build that regulates the the pressure and  stays between say 20-30c so you don't have the condensation?  Maybe having it to switch between 1 stage to 2? 

 

There is the case that has the compressor in the bottom that Linus did a build on which went to sub 0 I think? Surely a smaller compressor means higher temps to reach that 20-30c?

 

Thoughts? Ideas? Correct me if I'm wrong? Is it already out there?

Type of gas does affect the temperature since the temperature at which it evaporates is fixed.

 

If you want to stay at 20-30 it makes no sense using a compressor in the first place, watercooling with an oversized radiator will do that just fine.

If you really want to keep everything close to 0c, you would probably find it easier to use a household refrigerator system (using HFC-134a (1,1,1,2-Tetrafluoroethane)). The system is relatively easy to maintain once it's built & runs at a reasonably low pressure. Make no mistake though, building this system won't be without risk!...

as long as yer above dew point, condensation won't happen unless atmospheric pressure increase

what is the dew point? i heard even blowing ac at it can cause condensation over time. that's when cold meats hot right?

The temperature at which water in the air condenses in the current conditions (air humidity).
