喷水室典型空气处理过程中空气流速的实验研究

针对纺织厂空调系统的核心-喷水室,研究喷水室内处理空气的冷却减湿和等焓加湿两个典型热湿交换过程。提出Re准数对传热传质有显著作用,而Re数的大小取决于流体速度。通过实验研究当空气流速从3m/s提高到5m/s时对喷水室热湿交换性能的影响,从而确定空气流动速度因素对两个热湿交换效率的影响趋势。根据拟合的数学曲线,总结出当空气的流动速度提高后,热湿交换效率相应提高。从而推动高速喷水室在实际工程中的应用。

The Research on velocity of air in typical handling processes in air-washer room

This article studied the two typical heat and mass transfer processes,the cooling dehumidification and the isenthalpic humidification in the core part of textile mill air-conditioning system i.e.the spray type air washer room.This paper demonstrates that the Reynolds number(Re),which is determined by the velocity of air flow,plays an important part in heat and mass transfer process.By doing research on the heat and mass transfer efficiency when the velocity of air flow changes from 3m/s to 5m/s,and the analysis of experimental data and diagram,we can get the conclusion that the heat and mass transfer efficiency goes up when the air velocity increases.This will benefit the improvement and application of the air conditioning system with spray type air washer of high air velocity.
