The process was used in the Apollo missions to cool the LM and the EVA suits. Water ran through a porous metal block exposed to the vacuum. Water first sublimated, then an ice crust. Turning water into vapor needs a lot of energy, thus the method is very effective.

The method is still used with EVA suits.
