电加热相变材料蓄热地板采暖的热性能模拟

为消除电采暖引起的电网峰谷差并降低采暖运行费用，该文提出了一种带有相变材料潜热贮能板的地板电采暖系统，并建立了分析此系统热性能的地板和房间理论模型，对给定的电加热相变蓄热地板采暖房间，模拟了室内空气温度和地面温度的变化，藉此分析了我国几个气候地区冬季该系统的应用效果，结果证明此采暖方式在使房间热负荷不大的建筑和气候条件下，基本能满足人的热舒适性要求，有较好的应用前景。

SIMULATION OF THERMAL PERFORMANCE OF UNDER-FLOOR ELECTRIC HEATING SYSTEM WITH LATENT HEAT THERMAL ENERGY STORAGE PLATE

A structure of under~floor electric heating system with latent heat thermal storage plate was presented.Such system is capable of applying the electricity at night that may be much cheaper than that at daytime to heat the occupied space so that the electric tariff may be lower a lot and the electric load at daytime may not increase.A theoretical model of analyzing the thermal performance of a room applying such system in winter was developed. By modeling and simulation,the indoor air and floor temperature of the room was calculated for a certain room in different climate regions,which testified the feasibility of the heating mode.
