Closed water cooling tower absorbing heat when the water evaporates to cool the cooled liquid. The cooling performance of a closed circuit cooling tower depends on the ambient wet bulb temperature.Below is two type of closed cooling tower:
1.Cross flow closed type cooling tower
In cross-flow cooing tower,water falling vertical from top tower,outside air via filler horizontal,water fall across the airstream.Advantage as following:
(1) Low power consumption,excellent of performance of heat exchange.
(2) Compact structure,Space Saving,less investment of infrastructure.
(3) Low water loss,economic advantages of using recycled water for cooling.
2.Counter flow closed type cooling tower
In counter-flow tower design, the flow of the air is in the opposite direction of the spray water.
(1) Few cooling blind area,high thermal efficiency.
(2) Design of equipment is compact,automatic digital display,easy to operation and maintain.
(3) The tank of cooling tower adopts closed loop, eliminate clutters go into the tower body to produce spraying blocked;
