摘　　要：目前CO2在超临界、跨临界和亚临界范围都有应用,现在99%的低温制冷系统可以由NH3/CO2复叠式低温制冷系统完成,事实上任何蒸发温度高于-55℃的系统都可以采用CO2。本文将讨论CO2制冷剂的优点、缺点,以及CO2在食品加工和冷藏业中应用前景。CO2 as a natural refrigerant can be used in hypercritical, transcritical and subcritical in recent studies. It is convinced that 99% of all low temperature refrigeration duties may be done with CO2/NH3 cascade systems, and any other application requiting temparaturcs down to -55℃ could be done CO2. Here we will deal with the advantages, disadvantages and primise of CO2 refrigerant in the industrial food processing and cold storage industries.
