| Abstract: | 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 ℃. |
