摘　　要：从低温制冷剂的发展背景、环境影响、性能、安全性及成本等5个方面着手,比较目前在用或者将在低温冷柜中应用的几种制冷剂R22,R404A,R290和CO2在上述几个方面各自的特点。结果表明,R290将是一种用于低温冷柜的很有潜力的制冷剂。Mainly analyzes some refrigerants from five aspects, such as the low-temperature refrigerants development background, the environmental impact, the performance, the safety and the costs. Mainly compares the refrigerants which were or being used in the low-temperature cabinet freezers, such as R22, R404A, R290, CO2. The comparison results show that R290 will be a potential refrigerant in the low-temperature cabinet freezers.
