| Abstract: | In this paper,a thermodynamic process for obtaining the 150K temperature range was proposed based on the mixed-refrigerant using Linder refrigerator with pre-cooling cycle.The experimental setup was established.The system performances were investigated under different composition of ternary refrigerant(R23/R14/Ar).The experimental results show that the best ratio of ternary refrigerant(R23/R14/Ar) is 0.46:0.39:0.15,the refrigerating temperature without heat loads is 150K and the cooling-down time is 85min. |
