浅谈湿式空冷器

Preliminary Discussion on the Wet Air Cooler

直接空冷空调器在夏季高温天气下出力受阻,这不仅影响其制冷量,而且对其安全运行也存在重大隐患。针对以上问题,可采用湿式空冷器降低空气侧入口温度,从而改善空冷器的换热效果,提高机组运行的经济性和安全性,对直接空冷机具有推广应用价值。介绍了不同类型的湿式空冷器传热原理及其工作流程,通过焓湿图表示出直接空冷器和不同类型湿式空冷器的传热过程,并进行分析对比得到不同类型湿式空冷器的优缺点,指出了不同类型湿式空冷器适用情况。

The output of air conditioning is blocked for high temperature in summer, which not only affects the refrigeration capacity, but also hides danger to its safe operation; aiming at these problems, the wet air cooler can be used on the air side for reducing entrance temperature, so as to improve the heat transfer effect of air cooler, the economy and the high security of the unit operation;it’s valuable for popu-larization and application of direct air cooling. Heat transfer principle and working process of different types of wet air cooler are described through psychrometric chart showing the heat transfer process of direct air cooling unit and different types of wet air cooler; the advantages and disadvantages of different types of wet air cooler are compared, presenting the applicable condition of different types of wet air coolers.
