How would you design an ammonia system.... in space
Looks like another requirement to be an astronaut is to be an ammonia tech.

After reading this article I was wondering how one would build an ammonia refrigeration system in space.
How would you deal with the fact of no gravity, all the liquid would not sit at the bottom of the High pressure receiver, and the pumps would not have sufficient NPSH.
Or how would you condense without wet bulb or even an atmosphere to reject heat to.
