摘要

液体冷媒融霜是一种新型的融霜方法。介绍了液体冷媒融霜实验装置，研究了在不同负荷不同库温下的融霜过程，从库温、融霜时间、制冷系统运行状态等方面分析了液体冷媒除霜系统对冷库的影响。实验结果表明:冷媒融霜可通过高压液体制冷剂与冰霜的热交换过程得到过冷来回收冰霜冷量。在被融霜蒸发器停止融霜后切换的瞬间，库温有较大幅度的上升。无负荷实验库温高于-5℃时，融霜过程库温依旧降低，说明液体冷媒方案可以用于制冷过程不能停止的速冻装置上。

Abstract

Hot liquid defrosting is a new method of defrosting. This paper introduces experimental facilities on hot liquid defrosting.The influence of hot liquid defrosting on cold storage was analysed through the aspects of cold storage temperature

defrosting -time and the working condition of refrigeration system. The results show that hot liquid defrosting can recover cold energy by heat transfer between high-pressure liquid refrigerant and frost. After the defrosting process

temperature in cold storage increases considerably. The temperature still reduces during the defrosting process under no-load experimental conditions when the temperature is higher than -5 degree at the beginning of the experiment

which implies that the hot liquid defrosting program can be applied to the quick-freezing device.
