1, water in the tower filler, water top-down, air bottom-up, the two flow to the opposite kind of cooling tower.
2, Countercurrent cooling tower thermal performance is good, divided into three cooling sections:
① cloth water to the top of the filler this space, this section of the water temperature is higher, so can still pass heat to the air.
② filler water and air heat exchange section. ③ filler to the Pool Space water section, water in this section is cooled called "tail effect." The water temperature in the north of China can be reduced by 1-2 ℃.
To sum up, the Countercurrent tower than the cross-flow tower in the same case, the packing volume is about 20% small, the Countercurrent Tower heat exchange process is more reasonable and high cold efficiency. 3, water distribution system is not easy to clog, water filler to keep clean not easy to aging, moisture reflux small, antifreeze ice measures easier. Multiple can be combined design, winter with the required water temperature water can be combined with a single operation or all the shutdown of the fan. 4, Construction and installation maintenance is easy, low cost, commonly used in air conditioning and industrial large, medium-sized cooling circulating water.
