Abstract: The energy consumption evaluation indexes of fan units and pipe network system are obtained by referring to national standards and setting up a subtarget set of energy consumption evaluation,AHP analytic hierarchy process was used to analyze and compare the factors affecting energy consumption, and EXCEL software was used to deal with them. The influence degree of each factor on energy consumption was obtained, namely the weight of each factor.Using fuzzy mathematics,combining with the weight of all the factors obtained,evaluate the energy consumption for fan unit and pipe network system.Verified by examples,the system is in excellent condition,and it is consistent with the actual situation.

Key words: Fan unit, Energy consumption evaluation, Analytic hierarchy process, Membership function, Fuzzy mathematics

摘要： 参考国家标准，选取风机机组与管网系统能耗评价指标，建立了能耗评价子目标集，利用AHP层次分析法，对影响能耗的各因素进行了分析比较，并利用EXCEL软件对其进行处理，得到了各因素对能耗的影响程度即各因素所占的权重。根据隶属度函数及公式计算、专家评分得到判断矩阵，根据模糊数学原理，结合所得到的各因素所占权重，对风机机组与管网系统进行了能耗评价。通过实例进行验证的结果表明，此次验证的系统处于非常好的状态，与实际状况相符。
