All kinds of stuff was used for refrigeration,
including sulfur dioxide and ammonia. Doubt that
they were used together. Many of the fluids were
toxic and probably one of the reasons for the
switch to freon. Of course ammonia is still used
in absorption refrigerators used in many RV's and
industry. Doesn't seem to worry most people.
