Abstract
A single compressed and four-stage segregating auto-cascade refrigeration system was developed in this paper, the temperature of the liquid coolant in the tank with 5L could reach 150K. Cooling process after throttling was analyzed, and the effect of the different proportion of the refrigerants was also pointed out. Experimental results show that it takes nearly 4 hours and 12 minutes to realize the temperature drop of secondary refrigerant in the tank from 290K(15°C) to 150K, and that the lowest temperature could reach -120°C and the refrigeration capacity was about 7 W.
