显热蓄热式电暖器供暖室内温度场的实验研究

Experiment on Indoor Temperature Field of Sensible Thermal Storage Electric Heater

基于人工气候室内温度场的实验研究,搭建了较高密度测点的温度场测试试验台,对室内水平、垂直方向上的温度随时间的变化规律以及室外温度及蓄热时间对气候室温度场的影响进行研究。实验结果表明,显热蓄热式电暖器供暖下室内水平温度梯度较小,但头脚温差大;室外温度越高,蓄热时间越长,电暖器保持其高温状态的能力也越长。采用多种数据处理方法对数据进行分析比较,结果表明,中位值方法更能反映出局部区域的温度状况。

On the basis of the experimental study of artificial climate indoor temperature field,the temperature field test bench of high density measuring point was built,the change rules of indoor temperature in the horizontal and vertical directions along with time were investigated,and the effect of outdoor temperature and heat storage time on the temperature field in the climate chamber was studied.The results show that the horizontal temperature gradient was small,but the air temperature difference between head and foot was large.The higher the outdoor temperature and the longer the heat storage time,the greater the ability of the electric heater to maintain its high temperature state.The data were analyzed and compared by various data processing methods.The results show that the median value method reflected the temperature of the local area better.
