基于层次分析法模型对农村热源方案的前景分析

Prospect Analysis of Rural Heat Source Scheme Based on Analytic Hierarchy Process Model

在当今政策和能源结构的基础上,采用层次分析法,以经济型、对环境的影响、适用性、技术性为准则层,对生物质锅炉、燃煤锅炉、地源热泵在农村公共建筑的前景性进行了综合评价分析,结果表明:三种热源中,生物质锅炉在当前农村最具有发展前景性,若是地源热泵克服其三大难题——初投资过高、地埋管占空间过大、地热换热器全年的热平衡,也将在农村会有广阔的发展前景。

Based on today's policy and energy structure,this paper adopts the analytic hierarchy process,which is based on economic,environmental impact,applicability and technicality.Biomass boilers,coal-fired boilers and ground-source heat pumps are used in rural areas.The comprehensive evaluation of the prospects shows that among the three heat sources,biomass boilers have the most promising prospects in the current rural areas.If the ground source heat pump overcomes its three major problems–the initial investment is too high,and the buried pipe takes up space.The thermal balance of large and geothermal heat exchangers throughout the year will also have broad prospects for development in rural areas.
