IIR documentSummary
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.
