摘要
一个典型工业制冷装置被选为研究对象。其全年的压缩机运行规律被分析。系统运行压缩机的制冷量与全部压缩机制冷量的比值被定义为部分负荷率。分析发现,该对象30%负荷率占全年运行时间的66.4%。根据部分负荷规律,提出了若干压缩机优化配置的措施以提高全年运行效率。一个工程实例分析揭示,压缩机的优化配置不仅可以减少运行成本,而且可以减少工业制冷系统的初投资。
A typical industrial refrigerating plant is selected for analysis.The operational regulation of the compressors over an annual period is determined.The ratio between refrigerating capacity of the operating compressors and total compressor capacity is calculated and defined as the part-load ratio of the plant.It is found that the plant was operating at 30%part-load for 66.4%of the annual operating time.Some measures for optimal configuration of compressors based on part-load are proposed to improve annual energy efficiency.A case study further reveals that optimal configuration of compressors will not only decrease operational costs,but also decrease capital investment requirements of the plant.
