Abstract   Steam compressed refrigeration system may be divided ammonia refrigeration system and freon
refrigeration system according to used differant refrigerants. Refrigeration system’s property, construction and
application extent are differant because of being used differant refrigerants.This essay tries to compare the difference
between Ammonia refrigeration system and freon refrigeration system to help to select and decide suitable refrigeration
system.
