Abstract
The performance parameters of a single compressed and four-stage segregating auto-cascade refrigeration system were developed in this study. The temperature of the cryogenic tank went down relatively slow with the evaporating temperature and the refrigerant temperature for W. When the state of system is steady, the suction pressure of the compressor is 0.3 MPa, the discharge pressure is decreased slowly. When the temperature of cryogenic tank is below zero 118°C, the discharge pressure is 1.34 MPa. The lowest temperature could reach-18°C and the refrigeration capacity was about 7 W.
