摘要
测试了真空管内温升速率随时间的变化关系,通过错时开启真空管吸收太阳能的时间,消除了光照强度随时间波动的影响,获得了真空管内水的升温速率随水温变化的关系。研究结果对大型的用真空管给建筑集热供暖的工程设计具有重要的参考意义。
Determine the temperature increasing rate changing with the passing time in the vacuum tube. Start up vacuum tube absorbing solar energy successively at interval time to eliminate the light intensity fluctuation with the passing time, and establish the relationship of heating water rate changing with the water temperature in the vacuum tube. The determination results are of important reference significance to the engineering design for heating building with the vacuum tube thermal collectors.
