【Abstract】 This paper analyses the characteristics of some hydrocarbons (R290, RC270, R1270,R600a), R152a and their mixtures. Being compared with R12, the mixtures of R152a/R290,R152a/RC270, R290/R600a have good performance in the refrigerating system and they can be better as substitutes for R12 with high energy efficiency and environmental friendliness.
