利用层次分析法,引入供热系统的能量转换效率ECC指标,建立了供热方式的能耗、经济和环境3个指标准则层,以供热3E为决策目标进行综合评价。另外,利用供热系统总经济费用进行评分比较,总经济费用包括能源消耗所征收的能源税、环境排放所征收的环境税和供热系统的综合年费用。计算结果表明,层次分析法用来评价供热系统具有科学性和综合性,可进一步用于各种供热方式组合的城市供热系统评价。
Analytic Hierarchy Process (AHP), the energy conversion efficiency (ECC) index of heating system is introduced to establish the three criteria of energy consumption, economy and environment for heating mode, and the comprehensive evaluation of heating 3E is made. In addition, the total economic costs of the heating system are scored for comparison. The total economic costs include energy tax levied on energy consumption, environmental taxes levied on environmental emissions, and the comprehensive annual cost of the heating system. The calculation results show that AHP is used to evaluate the heating system is scientific and comprehensive, and can be further used for the evaluation of urban heating system with a combination of heating modes.
