摘　　要：太阳能光热的充分利用是发挥可再生能源价值的有效途径。通过对建筑中太阳能光热和市电耦合的相变蓄能地板的供暖情况进行实验分析。结果表明:同时加热5 h,普通房间较相变房间室温温升较快,但冷却相同时间发现相变房间的温度更高;相变房间的垂直温差更小,温差最大仅为1.05℃,平均垂直温差为0.32℃,平均垂直温差远小于人体所能感知的温度变化最小值。总体而言相变房间升温过程相对缓慢,保温效果更好,能延长保温时间,房间热舒适性也相对更加良好。The full utilization of solar energy is an effective way to bring the value of renewable energy into full play.The heating condition of phase change energy storage floor coupled with solar heat and electricity is analyzed experimentally.The results show that the room temperature of the ordinary room rises faster than that of the room with phase change after simultaneous heating for 5 h,but the room temperature of the room with phase change is higher during the same cooling time.The vertical temperature difference in the phase change room is smaller,with the maximum temperature difference of 1.05℃and the average vertical temperature difference of 0.32℃,which is far less than the minimum temperature change perceived by human body.In general,the temperature rise process of phase change room is relatively slow,the insulation effect is better,the insulation time can be extended,and the thermal comfort of the room is relatively better.
