建立一个太阳能蓄能通风系统的理论模型,以计算该系统白天蓄热量和夜间通风量。以昆明市气象参数为依据,分析了采用相变材料的相变温度分别为38、44、50、63 ℃时,该系统通风量与烟囱倾角的变化关系。计算结果表明,对于不同相变材料,无论在何倾角下,他们的蓄热量大小趋势都是一致的,即相变温度越高,蓄热量越小。综合考虑通风量和通风时长2种因素,系统最佳倾角应该为45°,而最佳相变材料应为38 ℃十四烷酰。
A mathematical model of solar energy storage ventilation system was built in order to calculate the heat storage during daytime and the ventilation rate during nighttime. Based on meteorological parameters of Kunming in China
phase change materials(PCM) were used at the temperature of 38 ℃
44 ℃
50 ℃ and 63 ℃ respectively to search the relationship between ventilation volume and the angle of chimney. The modeling calculation results show that for different phase change materials
and in any angle
the trend of heat accumulation is consistent
namely heat accumulation is smaller with a higher phase change temperature. Considering both the average hourly ventilation volume and the duration
the best angle of this system should be 45°
and the best phase change material should be 38 ℃ myristoyl.
