摘　　要：CO_2制冷系统的运行效率与蒸发温度直接相关,蒸发温度越低,CO_2制冷系统的经济性越明显。本文结合实际工程案例对相同条件下的CO_2复叠制冷系统与单级和双级压缩的氨直接冷却系统的能耗进行了对比分析。CO2 refrigeration system efficiency is directly related to evaporation temperature, the lower evaporation temperature, the higher system efficiency. In this paper, the energy consumption of the CO2 cascade refrigeration system and the energy consumption of single-stage and two-stage compressed ammonia direct refrigeration system is compared under the same conditions with the actual engineering case.

关 键 词：CO2 复叠制冷系统 能耗
