直冷两门冰箱应对新欧标冷冻能力提升研究

Research on Freezing Capacity of New Energy Efficiency Standards for ManualDefrost Refrigerators-freezer

本文结合冰箱新欧标测试方法和生态指令要求,针对载体BCD-250直冷两门冰箱冷冻能力存在的问题,从标准测试、制冷系统配置和控制系统进行改进。结果表明:优化冷冻负载分布,改进冷藏蒸发器配置和增加冷藏补偿加热器的方式可满足新欧标对冷冻能力的高标准要求。

This work combines the new European standard test method for refrigerators and the requirements of the ecological directives to improve the problems of the freezing capacity of the BCD-250 Manual Defrost Refrigeratorsfreezer from standard testing,refrigeration system configuration and control system.The results show that optimizing the freezing load distribution,improving the configuration of the refrigerated evaporator,and adding a refrigerated compensation heater can meet the high standard requirements of the new European standard for freezing capacity.
