That should be OK. It's very similar to the commercial phase-change units.
It uses R-134A though, which is fine, but maybe you could find one with another refrigerant? Danfoss doesn't seem to have one. |

Thanks for the fast reply bigben2k
What's wrong with the R-134A stuff? Is it a good idea to have the compressor run off your PS? Or is an AC version better? No difference? I was also looking at this article. Is this typical of how to build a water chiller? |

There's nothing wrong with R-134A.
R-12 or R-22 would perform better, but R-134A is probably a lot easier to get, heck even at Wall-Wart! |

That is a weak litle compressor, I think vapochills use it.Don't waste your time with it, it wouldn't chill water good at all.
An a/c compressor will do much much better yes, but they are a bit noisy and big.Refrigerator compressors are what you wan't. R134a is a lousy refrigerant, it has a high boiling point and it doesn't have a great heat capacity.Propane is of course the best refrigerant to use if you can't get something like R22.R12 is a lousy refrigerant also. Propane is like the overclockers dream.

Actually no I don't like propane that much, I would much rather have R12.But the fact is, propane is a very cheap and easy refrigerant to get that perform extremely well.It has a low boiling point, and performs very well.
It performs much much better than R134a and R12, but not R22.
