| Abstract: | To obtain a convenient and reliable method for research at-80℃,a two-stage cascade refrigerating cycle cooling equipment was designed and set up.The R404A and R23 were used as refrigerants in the two stages respectively.The experimental results indicate that the cooling equipment can provide refrigerating output at-80℃ stably.The structure of this two-stage cascade refrigerating cycle cooling equipment was simple,and it will have a better application such ascryo-medicine.The test result was analyzed based on reasonable predigestion,and the improved measure was proposed. |
