基于能效模拟的高效制冷机房系统指标研究
摘要：
针对福建省需要兼顾夏热冬冷和夏热冬暖2个气候分区的特点,建立了办公、商业、医疗3类典型建筑模型,通过全年逐时负荷模拟与能效分析,构建了分区分级的能效指标体系。运用k均值聚类算法进行数据分析对比,确定了福建省高效制冷机房一星级至三星级的能效限定值,一星级能效指标与国家标准持平,二星级、三星级略高于国家标准。
Abstract：
This study focuses on the characteristics of two climatic zones of hot summer and cold winter and hot summer and warm winter for Fujian Province, establishes three typical building models of office, commercial, and medical buildings, performs annual hourly load simulation and energy efficiency analysis, and establishes a zoning and hierarchical energy efficiency indicator system. The k-means clustering algorithm is used to analyse and compare the data, and the energy efficiency limit values for one-star to three-star high-efficiency refrigeration rooms in Fujian Province are determined. The one-star energy efficiency indicator is the same as that in the national standard, and the two-star and three-star energy efficiency indicators are slightly higher than those in the national standard.
