摘要:
以实验的方法对采用填料塔式再生器的溶液除湿蒸发冷却空调系统的再生性能进行研究,得出了再生器热源温度在55.5 ℃工况下的传质系数和热源温度对出口参数有影响的结论.同时发现传质系数平均值约为0.32 mg/(m2·Pa·s),根据实验数据提出提高填料塔式再生器再生性能的方法.同时提出一种蓄能密度高的相变潜能蓄能模式,并在理论上对其进行定量分析,结果表明该种蓄能模式的蓄能密度一般在1 000 MJ/m3以上,这表明该蓄能方法比常规蓄能方法更为有效.
Abstract:
Regeneration performance of regenerator with packed tower structure was studied experimentally for the liquor desiccant cooling air conditioning system. The mass transfer coefficients under the operation conditions of 55.5 ℃ heating source are obtained and the influence of heating temperature on outlet parameters is shown. It’s found that the mass transfer coefficient is around 0.32 mg/(m2·Pa·s). According to the experimental results, betterment measures are concluded for the regenerator. A phase-change latent energy storage mode with high energy storage density is brought forward and analyzed in theory. It is shown that under this mode the density of energy storage is generally over 1 000 MJ/m3, which means that this energy storage method is more effective than conventional ones.
