Background
Today, with the information technology changing day by day, large data centers are developing at a high speed under the background of new capital construction. The uninterrupted operation of the data center for 7x24 hours undoubtedly puts higher requirements on a counter-flow cooling tower (water cooling system).
The conventional counter-flow cooling tower sprays cooling water downwards from the upper part of the counter-flow cooling tower, cooling tower air inlet upwards from the lower part of the counter-flow cooling tower, the downward cooling water and the upward cooling tower air inlet achieve counter-flow (counter flow), heat exchange (direct heat exchange and evaporative heat exchange) between the cooling water and the cooling tower air inlet is carried out for cooling, and the cooled cooling water is directly supplied to a water-cooled refrigerator for use.
In summer, especially in extreme weather of high temperature and high humidity, the inlet air (outdoor air) of the cooling tower has high humidity (reduced evaporation heat exchange efficiency) and small temperature difference with the cooling water of the conventional counter-flow cooling tower (reduced direct heat exchange efficiency), so that the heat exchange capacity of the counter-flow cooling tower is reduced and the heat exchange is insufficient. The temperature of the cooling water outlet of the counter-flow cooling tower is increased, which causes the reduction of the cooling efficiency and the increase of the energy consumption of the water-cooling refrigerating machine.
