摘要：

R41 was selected to substitute for R23 in an auto-cascade refrigeration cycle with a rectifying column at-60℃.Performance comparisons and analyses were conducted when R1234ze(E)was selected as the less volatile component.An experimental apparatus was designed and established to compare the performances of R23/R1234ze(E)and R41/R1234ze(E)in the system.Both theoretical and experimental results showed that when adopting R1234ze(E)as the less volatile component, COP values decreased slightly and the compression work per unit volume decreased by 1/3-1/2 after the substitution of R41 for R23.Besides, the refrigeration capacity per unit volume also decreased slightly, but the refrigeration capacity per unit mass showed an obvious increase, which would result in significant refrigerant charge reduction.More importantly, the reduction in GWP of R41 would bring obvious environmental protection effect. © All Right Reserved.
