OK, should have looked some more, a guy has patented the process:

He uses solar to boil ammonia from ammonia water during the day, to separate out and store up liquid ammonia, then at night he releases the liquid ammonia to perform the refrigeration part by the ammonia turning to gas. Then he runs the gaseous ammonia through water to recover it/absorb it (forming ammonia water) and store it, then the cycle repeats the next day.
