摘　　要：供暖领域用电能供暖替代传统燃煤供暖方式,是减少雾霾的主要措施之一.将电锅炉和地源热泵技术等进行集成,基于能耗及经济成本等因素,建立分析模型,并通过调研数据对分析模型进行验证,分析电锅炉以及热泵在不同性能曲线(COP)的联合使用的运行策略,寻找最优的运行方案是实现电能替代效益的关键步骤.基于系统模型以及优化目标,借助计算机辅助编程,通过坐标轮换法,对模型进行分析和计算,得出采用地源热泵作为主供暖设施,电锅炉作为辅助供暖设施的是目前电能供暖综合最佳解决方案.As one of the main measures to disperse haze,electric heating systems will replace the traditional coal-fired heating systems in the field of heat supply.Integrating electric boilers and ground source heat pump,the analysis model based on energy consumption,economic costs and other factors is built.The analysis model is validated via the survey data and the co-running strategies of electric boilers and ground source heat pump in different COP are evaluated in order to find the optimal solution.These are the key steps for efficiency evaluation of alternative energy.Based on the system model and optimization goal,the coordinate rotation method is used to analyze and calculate the model through computer-aided programming.The best solution of electric supply is to use ground source heat pumps as the main heating facilities and electric boilers as an auxiliaries.
