could store 2.6 kg of R22 or R13B1/R152a (65/35 wt.%) mixture if completely
filled.This extra amount of refrigerant in the receiver during steady-state operations
resulted in a total system charge that would overfill the accumulator during cyclic
operation.This large mass fraction shift to the higher mass fraction of R13B1 resulted
in a large volumetric capacity by increasing the suction vapor density.Indeed this
option enhances the control over the mass fraction shift by adding one more degree
of freedom in terms of refrigerant storage,resulting in a 14 and 2% capacity and
COP increase,respectively,at the –8.3°C rating point.

答案和解析
资料来源:mulroy和迪迪翁,1986年.
可存储二点六千克的R22的或r13b1/r152a ( 35分之65小波变换.% )的混合物,如果完全
填补.这,这笔额外的制冷剂在接收期间稳定状态行动
产生了一个总系统负责将overfill蓄电池在循环
运作.这个大质量分数转移到较高的质量分数,导致r13b1
在一个大的容积,增加吸蒸气密度.事实上,这
选项增强了控制权转移的质量分数,加入一更多学位
自由而言,制冷剂的储存,导致在一个14日和2 %的能力和
缔约方会议的增加,分别在-8.3 ° C的评价点.
