摘　　要：为研究地板下送风式相变蓄热电采暖系统的热性能,有效利用夜间廉价电并提高室内环境的热舒适性,建立了分析此系统热性能的理论模型,并得到了实验数据的验证。藉此模型分析了一些重要因素对其热性能的影响,探讨了系统的热设计和控制方法。通过控制此系统的送风扇启停可保持室温在舒适区内,模拟计算了其在北京地区和其他一些采暖地区整个冬季的使用效果,结果验证了此系统的可行性。A model of analyzing the thermal performance of a new kind of under-floor electric heating system with shapestabilized PCM plates and air supply （for effectively using electricity at night and improving indoor thermal comfort） was developed. The model was verified by the experimental data. According to the model, the effects of various factors on the thermal performance of the heating system was analyzed. The results show that the indoor temperature in Beijing and other area can be controlled in the comfort range by starting and stopping air-supply fans during the whole heating season.
