【摘要】 随着我国城市规模的不断扩大以及人们对于居住环境要求的不断增高，而世界能源，尤其是我国能源形势十分紧张，如何节约能源，提高能源的使用率是我们应该研究的主题和趋势。我国的供热能耗占了北方全部能耗的将近20%，节能潜力十分巨大，因此推行供热系统改革，提高城市集中供热系统能源的有效利用率，具有重要的节能和环保意义。本文主要研究热源对多热源供热系统节能性的影响，并且利用模糊数学的方法对多热源供热系统进行评价分析，并编制了系统的评价软件。通过分析多热源供热系统的组成以及其优点，说明采用多热源供热系统的必要性。并从供热系统的组成：热源、热网和热用户着手介绍了多热源供热系统的节能方法。本文主要根据具体的例子，计算分析了热源容量和热源位置对于多热源供热系统节能性的影响，并且利用模糊数学的方法，对多热源供热系统建立数学模型，从多热源供热系统的节能性、经济性、安全性和环保性对该系统进行分析评价，并使用Visual Basic6.0程序简单编写多热源供热系统的评价分析软件，给出该多热源供热系统的评价值以及评价结论。更多还原

【Abstract】 With the expansion of our country and the increasing requirements of people for a livingenvironment, the situation of world’s energy, especially our country is very nervous. How tosave energy and improve the efficiency of energy is the themes and trends we should research.Our heating energy consumption is nearly20%of all the energy, and the energy savingpotential is very large.So pushing the heating system reform and improving the efficiency ofthe urban centralized heat supply system has the important meaning of energy saving andenvironment protection.This paper mainly studies the heat source’s effect of energy saving for themulti-heat-source heating system, and use the fuzzy mathematics method to estimate andanalyse the multi-heat-source heating system. At last compile a software to judge of thesystem.Through the analysis of the multi-heat-source heating system composition and itsadvantages, explain the necessity of the multi-heat-source heating system,and introduce theenergy saving methods of the multi-heat-source heating system from the heating systemcomposition: heat source, heating and hot users. In this paper, according to specific examples,calculate and analyse the affect of heat capacity and heat source to energy saving of themulti-heat-source heating system. And utilize the fuzzy mathematics to constitute themathematical model of the multi-heat-source heating system. Estimate and analyse themulti-heat-source heating system from energy saving,economy, safety and environmentalprotection. Use the Visual Basic6.0program to compile a simple analysis softwarein order togiven the value and evaluation conclusion of the multi-heat-source heating system.更多还原
