储热水箱是太阳能集热系统中的重要部件,储热水箱的分层特性直接影响太阳能集热系统的效率和热水出水量。本文研究了一种新型的储热水箱,在1.60 L/min和4.87 L/min两种流量下,得到了储热水箱出水过程温度分布和水箱各温度测点温度、分层数、斜温层厚度、混合数的变化趋势。新型的分层器在两种流量下均具有较好的分层效果,1.60 L/min流量下的分层效果相较于4.87 L/min流量下分层效果更好。
The hot water storage tank is an important component in the solar energy heat collecting system. The stratification of the hot water storage tank directly affects the efficiency of the solar heat collecting system and the hot water output. In this paper, a new type of hot water storage tank was researched. The temperature distribution of the hot water storage tank and the temperature at each temperature of the water tank at the flow rates of 1.60 L / min and 4.87 L / min were obtained. The number of stratification, Temperature layer thickness, the number of changes in the mixed trend. The new stratifier has good stratification effect at both flows, and the stratification at 1.60 L / min is better than the stratification at 4.87 L / min.
