无填料热源塔冬季吸热量分析

Analysis of heat absorption of non-packed heat source tower in winter

利用搭建的无填料热源塔实验平台实验,分析空气温度、相对湿度、溶液入口温度、气水比对热源塔吸热量的影响,对吸热量中的潜热吸热量和显热吸热量进行对比。结果表明:空气温度升高,溶液总吸热量增大但潜热吸热量减小;总换热量和潜热换热量随着相对湿度增高而增大,相对湿度较低时会抑制潜热换热量;气水比升高,热源塔吸热量增加;溶液入口温度升高,潜热吸热量和显热吸热量同时减少。

Using the non-packed heat source tower platform to carry out the experiment,the heat absorption of the heat source tower was study under the different air dry-bulb temperatures,relative humidity,air-water ratio,solution inlet temperatures.Comparing and analyzing the proportion between latent heat and sensible heat.The results show as the temperature increases,the total heat absorbed by the solution increases while the latent heat decreases,the heat absorbed by the solution increase with the air-water ratio increase,the total heat and latent heat transfer increased with the increase of relative humidity.When the relative humidity was low,the latent heat exchange capacity was inhibited.With the inlet solution temperature increase,both the latent heat and sensible heat decrease.
