摘　　要：以一实际冻结间的冷风机为研究对象,介绍了辅助热氨融霜的实验装置,对实验结果进行分析研究:与热氨融霜相比,其优势在于保证制冷系统连续工作,提高装置的日产量,具有制冷效率高,食品冻结速度增大等优点。An experimental device about assistanl defrosting for hot ammonia was proposed in this paper, based on an air-cooler in actual frozen room. The analysis on experimental resuh shows that： make sure the refrigerating system running uninterrupted, increase the output every day, have higher refrigerating efficiency and great frozen rate compared with hot ammonia defrosting.

关 键 词：冻结间 融霜 制冷效率 冻结速度
