摘要
自行复叠制冷循环以其结构简单、可靠性高、适应性强等特点 ,在能源、生物、医学和生命科学等领域得到了日益广泛的重视和应用。针对一个改进的自行复叠制冷循环 ,建立了该制冷循环的实验台 ,进行了不同配比的二元混合工质和三元混合工质的自行复叠制冷循环性能实验 ,得出了改进自行复叠制冷循环的降温特性图以及性能系数COP和制冷量与制冷温度的关系。
The Auto Refrigeration Cascade(ARC)system is widely applied in the fields of energy,biomaterial storage and cryosurgery due to its simple structure,reliable performance and low cost An experimental apparatus on the new ARC system,which uses binary and ternary refrigerant,is set up The system performances are investigated under different composition of binary refrigerant,and the cooling curves and relationships among temperature of refrigeration,refrigerating capacity and COP are acquired Finally,the comparison of performance parameters under steady operation is carried out
