摘要
以电热膜采暖系统为主要研究对象,通过人工气候室进行实验测试,分析该采暖系统蓄放热特性,并结合电散热器采暖系统进行室内热环境与人员热舒适性进行对比。实验表明:电热膜采暖系统电热膜采暖系统在升温期时室内空气温度的变化滞后电热膜层温度变化30 min,在稳定期时室内温度波动约为3℃。电散热器采暖系统可比电热膜采暖系统提前50 min让室内温度达到18.0℃,但电散热器采暖系统垂直温度梯度为1.6℃/m远大于电热膜采暖系统垂直温度梯度的-0.4℃/m。在相同的热舒适性条件下,电热膜采暖系统中室内温度可比电散热器采暖系统中降低0.5℃。本实验结论可为严寒地区电热膜采暖系统运行提供一定的依据。
Taking the electric heating film heating system as the main research object,the experimental test was carried out through the artificial climate chamber to analyze the heat storage and release characteristics of the heating system,and the electric radiator heating system was used to compare the indoor thermal environment with the thermal comfort of personnel.The results show that the temperature of the indoor air temperature in the heating film heating system is lagging behind the temperature of the electric heating layer for 30 min,and the indoor temperature fluctuation is about 3℃during the steady period;the electric radiator heating system can compare with the electric heating film heating.The system temperature is 18.0℃50 minutes ahead of time,but the vertical temperature gradient of the electric radiator heating system is 1.6℃/m,which is much larger than-0.4℃/m of the vertical temperature gradient of the heating film heating system;under the same thermal comfort conditions,The indoor temperature in the electric heating system can be reduced by 0.5℃compared to the electric radiator heating system.It is concluded that this experiment can provide a certain basis for the operation of electric heating film heating system in severe cold area.
