摘要
简述R404A/CO2复叠制冷系统与CO2低温载冷剂系统,并对各系统的能效情况进行理论分析。结果表明:当蒸发温度在-30～-50℃范围内时,复叠制冷系统的能效明显高于CO2低温载冷剂系统。
R404A/CO2 cascade refrigeration system and CO2 low temperature secondary refrigerant system are simply summarized, and the EER is calculated and compared. The results show that the EER of cascade refrigeration system is higher than that of CO2 low temperature secondary refrigerant system at the evaporation temperature from - 30 ℃ to -50 ℃.
