本文用实验方法研究了以低位余热蒸汽为热源的双级氨水吸收式制冷机的性能,初步得到了其变化规律,并介绍了该机在冷库与冷饮生产中推广应用情况。最后,将实验装置在设计工况下的各项性能指标与国外文献记录的数值进行了对比,同时将吸收式制冷机与压缩式制冷机作了初步的经济比较。 In this paper, the performance of two-stage ammonia water absorption chiller with low residual heat steam as heat source was studied experimentally, and its variation was preliminarily obtained. The application and popularization of this machine in the production of cold storage and cold drinks were introduced. Finally, the experimental device in the design conditions of the performance indicators and foreign literature compared the value of records, while the absorption chiller and compression chiller made a preliminary economic comparison.
