摘　　要：提出了一种利用定形相变材料蓄存夜间廉价电热,并能控制放热速率的地板下送风式相变蓄热电采暖系统。可有效利用夜间廉价电并提高室内环境热舒适性,搭建了应用此采暖系统的实验房间,测量了系统和室内空气的温度变化,分析了此采暖方式的使用效果。结果表明,该系统蓄放热性能较好。白天的电热负荷全部转移到夜间低谷电价时段,白天供热量可借送风量调节,冬季采用该系统供暖可满足热舒适的要求。A new kind of under-floor electric heating system with shape-stabilized phase change material （PCM） plates with air supply was put forward. The system can charge heat by using cheap nighttime electricity and discharge the heat stored at daytime, and may adjust the air flow rate to control the indoor thermal comfort degree. A prototype room with this system was built. The temperatures of the system and the indoor air were measured. The thermal performance of the system was analyzed. The results showed that the system can perform well and control the indoor thermal comfort degree effectively.
