家用电冰箱制冷系统启动过程研究

Study of Start-up Process of Refrigeration Systemfor Household Refrigerator

本文简要介绍了家用电冰箱制冷系统启动过程的试验研究与动态模拟分析方法及其结果。揭示了启动过程的压力、温度、工质质量分布和热力过程能量损失等变化规律。指出了启动过程存在无冷量输出期的主要原因；提出了电冰箱制冷系统提高动态响应能力和减少能量消耗的技术措施。

This paper briefly introduces the methods and results of experimental study and dynamic simulation of start-up process for household refrigerator. The variational laws of the pressure、temperature、refrigerant distribution and energy loss are revealed in this process. At the same time , the main reasoris why exists non-cold export period are discussed. The tech- nology measures improving dynamic response ability and reducing power consumption have also been put forward.
