低谷电蓄能供暖系统分析与应用

Analysis and application of heating control strategy of off-peak electricity heating system

电采暖作为集中供暖的补充方式,可用于建筑物独立采暖,具有污染少,设备占地空间小、方便易调节的特点。基于电蓄能的按需供暖策略,本文开发了一套低谷电蓄能供暖控制系统,可实现夜间蓄热、白天供热与补热。该系统在800m2示范场地的运行数据显示,与集中供暖相比,节省用户供暖费用88.12%,减少温室气体排放64.89%。

As a supplementary heating mode, electric heating can be used independently for buildings heating with less air environment pollution, less area occupation and convenient in maintenance and operation. An energy storage heating system （ESHS） using off-peak electric based on the on-demand heating strategy has been developed. It can realize the heating strategy and supplementary heating strategy at valley time and daytime. An ESHS has been applied in an 800 m2 building in Beijing. The data shows that comparing with the traditional central heating system, the ESHS saves the heating fees by 88.12, reduces the emission of greenhouse gases by 64.89%.
