摘要
冬季热风供暖房间由于空调系统参数的不合理以及热空气的上浮,工作区温度往往达不到要求。为提高热舒适,一个有效措施是开启办公室吊扇来驱使贴附在房间顶棚位置的热空气向下运动。本实验针对上海某办公室,研究了不同工况吊扇开启前后室内垂直方向不同高度测点温度的变化。实验结果表明:吊扇开启后工作区温度明显升高,室内温度梯度减小,热量利用率大幅提升,节能效果显著。
Because of the unsuitable parameters of air conditioning system and floating of hot air,the temperature of occupied space usually cannot meet the requirement in a hot air heating room.An effective method to improve thermal comfort is opening the ceiling fans,so that roof-attachment hot air can be driven downward.The present experiment discussed the variation of vertical temperature under different operation conditions,which was measured in an actual office in Shanghai.Experimental results showed that the temperature in occupied space rose obviously and temperature gradient reduced.It meant that coefficient of utilization promoted greatly and energy-saving effect was significant.
