Abstract: | The performances of refrigerants used in cascade refrigeration system was analysized and compared in this work. R404A/R508B was chosen as the refrigerant of ultra low temperature refrigeratore based on the above comparing work. An experimental apparatus of cascade refrigeration system was set up. The experimental results showed that the temperature of ultra low temperature refrigerator using R404A/R508B as refrigerant could drop to -82℃ within 6 hours. The system ran well and stably, which could meet the requirements of refrigeration of ultra low temperature refrigerator. |
