Evaluation Index System Of Suitability For Direct Conversion Of Electric Heating In Northern Villages And Towns

In recent years,thanks to the government’s strong support for clean energy heating,many electric heating demonstration villages have emerged across the country.However,due to the differences in the natural historical environment and living habits between villages and towns,the choices of electric heating methods are different,and the heating effect and the satisfaction of the residents are also different.How to improve the comprehensive benefits of electric heating in villages and towns,and realize the electric heating reform that the villagers are satisfied with is particularly important.Based on the above-mentioned problems,this article evaluates and analyzes the suitability of direct electric heating conversion in northern villages and towns,and makes theoretical contributions to the development and promotion of direct electric heating conversion in northern villages and towns.First of all,according to the scientific and reasonable construction principle,this paper selects and optimizes the evaluation index set for the suitability of direct conversion of electric heating in northern villages and towns from three aspects: field investigation,literature theoretical research and expert consultation,and establishes a hierarchical structure,and then draws 6 primary indicators and 25 secondary indicators.Secondly,in order to determine the weight of each indicator,this paper adopts the group analytic method and the Delphi method,and gathers a number of people who have at least 3 years of work experience in the heating-related field and have the title of engineer or associate professor or above in the field of electric heating in villages and towns.The expert’s effective questionnaire and the MATLAB language were used for calculation,and a complete evaluation index system for the suitability of electric heating direct conversion heating in northern villages and towns was obtained.The results point out that the economic index accounts for the highest proportion(0.3159)in the suitability evaluation index system for direct conversion of electric heating in northern villages and towns,and the highest proportion of initial investment(0.4206)among the three secondary indicators under the economic index.This result also truly reflects the actual needs of village and town residents.Finally,the suitability of electric heating in Zhujiayao Village,Shanxi Province(Electric Heating Film Demonstration Village)and Fanbao Village,Henan Province(Regenerative Electric Heater Demonstration Village)is quantitatively evaluated by the gray whitening weight cluster evaluation model.In order to facilitate the calculation,the model is programmed in MATLAB language to form software with operating interface.The two villages were inspected on the ground in terms of natural environment,natural resources,building and heating.Then,using self-made software to analyze the suitability evaluation category of heating.The results indicated that:(1)The suitability evaluation result of direct conversion heating in Zhujiayao Village is "suitable"(2)The suitability evaluation result of direct conversion heating in Fanbao Village is "slightly suitable".
