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。
At present, CO2 is used in supercritical, transcritical and subcritical ranges. Now 99% of the cryogenic refrigeration systems can be completed by the NH3 / CO2 cascade cryogenic refrigeration system. In fact, any system with an evaporation temperature higher than -55 ℃ Using CO2. This article will discuss the advantages and disadvantages of CO2 refrigerants as well as their potential applications in food processing and refrigeration.
