Remove R12 from an broken compressor ?
 

Hi!

I found this "old" compressor(a danfoss from 1990) laying around on my familys newly bought hotel ( yes we are the odd kind of people that live in wierd places)
When i first saw it i thought to myself. i WANT that radiator!
But then i came to think.. what about the coolant inside ? is it as bad for me as an angry cobra ? i dont want to risk my health because of this.

I really dont give a flying **** about the enviroment... so... is it dangerous to cut the lines ? for me myself and I.
A label says it uses r12 coolant.. some kind of freon isn´t it ?

i thought i should ask you guys before i get myself into trouble :)

There are several hazards to discharging freon yourself. Just take the whole rig down to an Auto service shop and have them discharge it (if there is anything left in it!) with their freon recycling equipment......then flush the remaining mineral oil out of the coil with a light detergent. Should be ready to use.

WTH? try and see if the compressor still works! if it does you got yourself the beginnings of a phase change system!!! yay!
but its pretty old, 92 you say? Danfos you say?
I would run it on something like, a hot coffe pot and see if it works ok ;)

R12 is non hazardous, but escaping freon may cause cold burns as it'll be very cold from the pressure change.

THanx alot guys !
I think i will get myself my hacksaw and start hacking it to pieces :)

so it is a complete setup, radiator, compressor, evaporator, or what?

do you know how powerful the compressor is? It mightn't be powerful enough for an athlon, or at least a heavily overclocked athlon

Just thought I would mention that the danfoss compressor is used in the vapochills, but they changed the freon from R-12 to R134a. R-12 is what the danfoss's were originally designed for, but environmental concerns made them change to the less efficent R-134a. If this unit still runs and still has a charge you can make a very powerful vapochill substitute out of it.

I was thinking the same thing as you, but i dont have the techical skills for it i think....

the unit was used to cool 2(!) MASSIVE restaurant fridges... so i think that it is sufficent to cool a little tbird or 2... :)

two massive resturant fridges, I guess you need to check the model number on that danfoss, the BD35 or the BD50 would be good for cooling a cpu anything bigger might not be such a good idea.

why isn´t it ?:D

I guess I could freeze over the whole goddamn room with it :) but hell i´d be getting great temps before that :)

isnt it there a way to throttle down the power of it ?
i dunno im not into phase change stuff :)

would it be possible to throttle it down with a resistor? so instead of 12v, it runs on 8v or something

you still havn't told me the model number. So I really can't give any suggestions, yes you can use a resistor to reduce the motor speed, but if its a large as your suggesting, it would take a very large resistor.

Grep

we are not talking 12v ... this is of course a 230v unit.

230volts, thats entirely different matter, most likely its 3 phase AC and no resistor is going to slow this baby down. AC powered motors speed can not be changed, they operate by locking the rotor to the line frequency or some multiple of it. Ok if your really determined it can be done, but its cheaper to buy an entire new motor. As a cpu cooler I would skip on this, its way to big, pulls way to much power and would turn your rig into a giant ice cube. Now that you have this giant ice cube, you turn it on and it begins to melt from the inside, since the outside is kept freezing by the big compressor the inside is in liquid due to the heat generated by the cpu and video card etc. So now your running your system in very cold water. Hmmm! this doesn't seem to be a real good idea, but look on the brite side, you don't have to worry about condensation.

hm.. after some concideration img going to rip apart the unit ant just take tha "radiator" from it.

230V isn't 3-phase usually, that's normally 415V, 230V is standard single-phase household supply

how big is the rad on it?

hm... about .... 30cm*40 cm ... dunno how thick but about 6-7cm ....
