Abstract
For a five-star hotel in Shanghai City,three configuration options for water chillers are proposed,and research and analysis are conducted from multiple dimensions such as economic cost,operation adjustment performance,and technical energy efficiency indicators.By comparing important indicators such as investment cost,operation energy consumption,and adjustment performance,the advantages and disadvantages of each option are comprehensively evaluated.The results show that scheme two has a relatively high initial investment,but it has outstanding performance in full-load range energy efficiency adaptation,adjustment accuracy,and operation flexibility.Scheme one,although technologically mature and with a moderate initial investment,has the weakest adjustment performance and is only suitable for scenarios with stable loads and mainly high loads.Scheme three has a low initial investment and good adjustment flexibility,but is only suitable for low-load scenarios with lower requirements for energy efficiency and accuracy,and has a relatively low overall energy efficiency performance.关键词
