供热节能评价体系及节能量建模研究

Research on energy-saving evaluation system for heat-supply and the establishment of energy-saving quantity evaluation model

我国供热领域普遍存在高耗低效、热舒适性差的问题,作为促进和实现供热节能的有效手段,节能评价指标体系的建立与评价办法的研究成为亟待解决的重要课题。针对目前节能评价研究多注重定性分析,缺乏科学可行的量化评价问题,借助物联网技术,建立以能耗基准模型为基石,以能耗修正系数为约束量的建筑物供热节能量评价模型。结合某高校历年的供热能耗数据,验证该模型的评价结果稳定可靠,为节能成效的科学评价奠定了理论基础,为供热行业的合同能源管理提供有力支撑。

There exists a universal phenomenon in the field of heatsupply,that is high consumption with low efficiency and poor thermal environment. As an effective means to promote and achieve energy saving,research on the establishment of evaluation index system and evaluation methods has become an important issue to be solved. According to the problem that currently studies of energy-saving assessment mostly focus on qualitative analysis rather than quantitative analysis,resulting in the lack of scientific and feasible quantitative evaluation theory,with the aid of the Internet of things,based on the benchmark model of energy consumption,under the constraint of energy consumption correction,a energy-saving quantitative evaluation model of buildings heat-supply system was proposed. Combined with energy consumption data of a university,the conclusions showed the reliability and superiority of the revised model,which finally provided a powerful theoretical support for the scientific evaluation of energy-saving effect and Energy Management Contracting.
