To effectively evaluate the performance of chiller selection options in regional energy systems,this study establishes an energy consumption and life cycle cost(LCC)assessment methodology for chillers.Using this approach,the paper analyzes and compares the host unit selection schemes for a specific regional energy station.The results demonstrate that multiple factors influence chiller performance in district cooling projects.Single-criterion evaluations fail to reflect the comprehensive performance of chillers,making the LCC-based assessment method essential.The study reveals that annual depreciation costs account for approximately 12％of the total life cycle costs,while annual operating expenses constitute about 88％.Since operating costs are directly correlated with chiller performance,greater emphasis should be placed on equipment performance parameters during the selection process.These findings provide theoretical support for the comprehensive performance comparison of chillers in regional energy stations and offer significant reference value for decision-making in related engineering projects.
