【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。更多还原

【Abstract】 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 requiring temperatures down to -55℃ can be used CO2.Here we will deal with the advantages,disadvantages and promise of CO2 refrigerant in the industrial food processing and cold storage industries.更多还原
