摘　　要：针对器官保存箱在转运过程中冷保存时间不足的问题,搭建了一套可为储冷介质间歇性补充冷量的微型蒸汽压缩式制冷系统,进行了实验系统稳定性测试及在2±3℃、2±4℃、1.5±4.5℃三种不同温度控制区间下的升降温测试。结果表明:在48 h稳定性测试中,储冷盒水温维持在-1.1~4.4℃,器官容器室水温维持在2.6~4.5℃;相比2±3℃,实验系统采用2±4℃、1.5±4.5℃的温度控制区间在单位降温时间上具有更长的升温时间。In order to solve the problem of insufficient cold storage time of organ storage box in the process of transport, a micro vapor compression refrigeration system for intermittently replenish cold capacity of cold storage medium was built in this research. The stability of the experimental system and the rising/cooling temperature tests under three different temperature control ranges of 2 ± 3 ℃, 2 ± 4 ℃ and 1.5 ± 4.5 ℃ were carried out. The results show that the temperature of the cold storage box is maintained at-1.1~4.4 ℃ and the temperature of the organ container is maintained at 2.6~4.5 ℃ during the 48 h stability test. Compared with 2±3 ℃, the temperature control interval of 2±4 ℃ and 1.5±4.5 ℃ in the experimental system has a longer temperature rising time per unit cooling time.
