基于实际数据的换热站能效评价方法的开发与研究

Development and Research on Energy Performance Assessment Method of Heat-Exchanging Stations Based on Real Data

本文对北京市近150座换热站进行了调研,并以实际调研数据为基础,采用多元线性回归的方法建立了换热站能耗预测模型,并检验了模型的准确性。同时,利用美国energy-star的能耗基准方法开发了换热站能效评价体系,并利用评价体系对实际案例进行了应用和示范。该换热站能效评价方法对于换热站的节能改造有十分重要的指导意义。

This paper establishes prediction models for multiple heat-exchanging stations by means of multiple linear regression based on nearly 150 real research data and determines the optimal model. The heat-exchanging station thermal efficiency evaluation system is developed by referring to the United States ＂energy-star＂ method and this system is applied and demonstrated in practical cases.
