摘  要  蒸汽壓縮式制冷系統(tǒng)按采用的工質(zhì)不同，可分為氨制冷系統(tǒng)、氟制冷系統(tǒng)。由于采用的工質(zhì)不同，制冷系統(tǒng)的特性、
構(gòu)造及應用范圍亦不同。此文試圖對氨制冷系統(tǒng)與氟制冷系統(tǒng)的異同進行分析比較，以利制冷系統(tǒng)的選擇和決策。
關鍵詞  氨制冷系統(tǒng)  氟制冷系統(tǒng)  選擇和決策

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.
