3 Compressors, are they good?

[metro.cl]

Hey guys, i'm able to get 3 compressors for free and i'm thinking of manking a phase change cooling system (1 or 2 or 3 stages?).

Now the first step is to knopw if any of the compressors are OK to be used, here are the pictures.

They are all working in refrigerators right now that are about to get thrown away because i got a new one.

i would use the first one. it is about 1/5 Hp, but dont expect very low temperatures...

forgot it made in Brazil :-)

Thanks Marvin maybe i'll just look around for a better one 1HP should be good enough right?

You can't expect anything from the 2 last compressors, they have too weak motors (can't go >150w input) so if you can cool down ~180w (assuming they aren't new), that would be good, and with those compressors don't expect to go <-15°C with this capacity.

You can't make a cascade out of them, even for a chipset cooler
