My mother had one of those, probably in the early 50s. When it was
replaced by a more modern unit, it was moved to the back porch and used in
the summer to cool melons and stuff. I guess this was high tech for the
back porch -- the neighbors had an ice box on theirs for similar uses.

I think those were ammonia-water absorption cycle refrigerators. I
seem to recall its making little gurgling noises from time to time.
