The test-bed of low temperature cabinet which type is SRL-CD2075HA has been set up.And the laboratory devices and testing process was introduced. The results show that R290 plays a better performance than R404A in the cabinet freezer system. The power consumeption of R290 is lower than that of R404A by 13.8% at most, and the charge amount of R290 is only 41.7% of R404A. The cooling rate of R290 is slightly upgraded than R404A, and the cost of R290 is much cheaper. It also accords with the international safe standards in low temperature cabinet through the safety analysis. Keywords R290 ；R404A ；low temperature cabinet 中。但由于R502 中含有R115 ，作为一种环境破坏 0 前言
