摘　　要：目的建立新型的相变储能电热地板采暖系统，分析系统的热舒适性和移峰填谷效率．方法采用DSC差示扫描量热计法选取最佳相变材料，建立电加热相变储能电热地板采暖系统，利用数据采集系统采集采暖期内系统和室内外空气的温度变化等重要参数，统计分析．结果相变储能电热地板采暖系统具有与普通地板采暖系统相似的室内空间温度场分布规律，人体热舒适性好，在夜间低谷电时期加热相变材料蓄热。用于白天供热，移峰填谷效率为53％～67％．结论采用相变储能电热地板采暖系统方式的房间内温度场分布增强了人体的热舒适性．系统可利用廉价低谷电储存热能。在峰平时段释放热量，有效实现移峰填谷．对提高人们生活质量，满足舒适性与实现建筑可持续发展有积极意义．The article is to find a new type of system, which is the phase-change heat-storage electric heating floor system, and analyze the heat comfort and the efficiency of established diverting peak power into low system. The method of DSC is used to select the best phase change material for heating floor system, and the phase-change heat-storage electric heating floor system is established. Some important parameters are gathered and analyzed by making use of the system of collecting data such as temperature change of the system and indoor air and outdoor air. The phase-change heat-storage electric heating floor system and the common heating floor system have similar distribution of indoor＇ s temperature to make people fell very comfortable. It can be possible to efficiently divert daytime electricity heat load to the period of time of low electrical charge at nights, the efficiency of diverting peak power into low is very obvious and reach 53 % -- 67 %. The temperature is evenly distributed in the room with phase-change heat-storage electric heating floor System, and the room＇s capability of heat comfort is better. The system uses the cheap electricity in vale time to deposit heat and releases it on apex time and can really achieve the purpose of diverting peak power into low, and it has also attached significance to improving the life quality and realizing the continual development of architecture.
