摘　　要：近年来,随着集中空调系统的应用日益普及,空调能耗呈增长趋势。空调能耗在建筑运行能耗中占据较大的比重,一个合理的集中空调系统能够有效地降低建筑对能源的需求。为此,本文构建了集中空调冷热源系统用能特性评价指标体系。从冷/热能利用、电能利用、系统能效及碳排放特性4个方面构建了相应的评价指标,建立了包括目标层、准则层和指标层的指标综合评价体系。利用层次分析法(AHP)与客观权重赋权法(CRITIC)确定了指标权重并计算了综合用能特性分值,建立了集中空调冷热源系统用能画像。以某办公楼集中空调冷热源系统为例,得到了其夏季工况和冬季工况的用能画像结果,验证了所提方法的有效性。In recent years,with the increasing popularity of the application of central air conditioning systems,the air conditioning energy consumption is a growing trend.The air conditioning energy consumption occupies a large proportion in building operation energy consumption.A reasonable central air conditioning system can effectively reduce the building's demand for energy.For this reason,this paper builds an evaluation index system for the energy use characteristics of central air conditioning cold and heat source systems.The corresponding evaluation indexes are constructed from four aspects,namely,cold/heat energy utilization,electric energy utilization,system energy efficiency and carbon emission characteristics,and a comprehensive evaluation system of indexes is established,which includes the target layer,criterion layer and index layer.Using the analytic hierarchy process(AHP)and the criteria importance though intercriteria correlation(CRITIC),the weights of the indexes are determined and the scores of the comprehensive energy use characteristics are calculated,so as to establish the energy use portrait of the central air conditioning cold and heat source system.Taking the central air conditioning cold and heat source system of an office building as a case,the results of the energy use portrait are obtained for the summer and winter working conditions,which verifies the effectiveness of the proposed method.
