Dual purpose vacuum desalination ?

[Externet]

Hi.

Would partial vacuum desalination or distilling produce also cooling as for 'air conditioning' ?

 

The vessel containing the liquid being distilled will get cold, right ?

Evaporation does cool the liquid, BUT for air conditioning you need <<+30°C, possibly +15°C at the liquid, and then the vapour pressure is tiny. My gut feeling is that compressing the vapour then to obtain the liquid gets costly.

 

Climatisers use to produce condensation water from the air. This water isn't very clean.
