mixed flow series closed cooling tower

Mixed flow series closed cooling tower 

closed circuit cooling towers are routinely selected for numberous commercial and industrial process cooling applications.

 some examples include:

water-source heat pumps

self contained cooling units

chillers

free cooling applications

data centers

hybrid evaporative/ dry cooling 

cooling special fluids

compressor jacket cooling , intercooling, aftercooling

machine jacket cooling

induction furnaces

consolidating mutiple loads into a single cooling unit

Advantages:

1. protect process fluids from contamination

2. maximize system efficiency by reducing fouling and scaling tendencies

3. reduce system energy costs

4. reduce system maintenance costs

5. reduce installed cost and space requirements

process principle

working fliud is flowing inside the coils which is enwrapped by the spray water outside. The heat of water is conducted by coil and become the saturated wapor when meet the water and the air.  The heat is exhausted out of the tower by the fan and the water is collected back to the water tank for recirculating. The spray water is cooled down when pass the PVC fills  in the circulating process and flows with the same direction with the fresh air and the coil mainly cooled by sensible heat conduction. so this type cooling tower is widely used for high temperature cooling media.
