摘　　要：介绍以工业余热为热源的单级氨水吸收式制冷机在工业制冰(蓄冷)与冷藏中的应用。初步论证了该机在生产中的性能和变化规律,用(火用)效率和当量热力系数分析了该机回收余热的经济效果,提出了实际操作过程中主要注意事项。并且用该机与压缩式制冷机进行了技术经济比较,证明其在工业余热升级利用及节能增效中所起的作用。This paper deals with the application of one stage ammonia absorption type refrigerator based on industrial waste heat recovery in industrial ice making (cold storage)and refrigeration. A preliminary assessment of its performance and variation relationship of efficiency during its operation has been given. The economic results from the use of waste heat is studied based on exergy efficiency and equivalent thermal factor.Some main precautions in the course of practical operation are also put forward.A technical and economic comparison of the said type of refrigerator with a compression type refrigerator demonstrates that the former has some advantages in respect of industrial waste heat utilization and energy earing.
