Structure of KMB <Closed> type Cooling Tower
Design concept-wise, the closed cooling tower is the opposite
of the open type in the sense
that circulating water never contacts ambient air during cooling process. There
are two independent
sources of water used for the closed type tower : Circulating water and spray
water.
Circulating water runs only inside a totally enclosed copper tube while spray
water runs down through.
infill. In this system, spray water cools circulating water running inside the
copper tube circuit without
contacting with each other directly.
In this way water never gets concentrated due to the fact that no evaporation
takes place in the tube.
Based on this fact, the equipment such as chiller is totally protected against
scale, and time & cost for
maintenance can be minimized.
In the region under low W.B. temperature (about 8℃), closed-type cooling
tower can be connected to
main cooling equipment directly to function as “COLD WATER GENERATOR” such
as chiller.
This system is called “free-cooling” and it greatly contributes to
energy-saving.
| Heat exchanger : (Coil & fillings) | Seamless phosphorus dioxide copper tube is used for the
circuit, and the filling" pieces are loaded at each individual stage to maximize cooling efficiencies. |
