Working fluid flowing inside of the coils,which is enwrapped by spray water on the outside.
The heat of water is transferred by coil and become the saturated vapor when meet the water and air.
The heat is exhausted out of the tower by the tower by the top fan; water is collected back to the bottom
tank and circulates continuously. Teh spray water is cooled down via PVC radiation fin in the process
of circulation, and flows n the same direction with the fresh wind. The coil mainly takes sensible heat
travel style. The most benefit of this style is can avoid scale formation on the outside of
thecoil. And this will apply especially to dealing with high temperature fluid (e.g. 60°C) or the fluid need big
temperature difference (e.g. 60°C to 35°C).
