基于层次分析理论的住宅供暖末端择优方法研究

Selection method of residential heating terminal units based on analytic hierarchy process

利用层次分析理论从经济性、热舒适性等6个方面建立了住宅供暖末端综合评价模型。采用全寿命周期成本理论给出了供暖末端经济性评价方法。对不同供暖末端房间的热环境进行数值模拟,得到不同室内设计温度下末端房间的PMV-PPD值,作为热舒适性评价的依据。通过调研,得出不同末端在美观性、可靠性、空间占用、室内声环境指标下的评价结果,以及不同气候区、城市/农村、不同收入水平情况下,6个评价指标间的权重关系。对供暖工程案例分析发现,供暖末端综合评价模型能为选择适宜的末端方案提供依据。

Based on the analytic hierarchy process （AHP） theory, establishes a comprehensive evaluation model of residential heating terminal units from six aspects of economy, thermal comfort and so on. Presents the economic evaluation method of heating terminal units based on the theory of life cycle cost. Numerically simulates the thermal environment in the rooms with different heating terminal units, obtains the PMV-PPD values of heating terminal unit rooms at different indoor design temperatures as the basis of thermal comfort evaluation. Through the investigation and research, concludes the evaluation results of different heating terminal units in the aspects of aesthetic, reliability, space occupancy, indoor sound environment indicators, and the weights of the six evaluation indexes in different climate areas, cities and rural areas as well as different income levels. Based on the case study of heating projects, the result shows that the comprehensive evaluation model of heating terminals can provide a basis for the selection of the optimal terminal program.
