counter flow cooling tower design, the air flow is opposite to the water flow. Air flow enters to an open area under the fill media, and is then drawn up vertically. The water is sprayed through pressurized nozzles near the top of the tower, and then flows downward through the fill, opposite to the air flow.
some of Advantages of the counter flow cooling tower design:
- Spray water distribution makes the tower more freeze-resistant.
- Breakup of water in spray makes heat transfer more efficient.
Few disadvantages of the counter flow cooling tower design:
- Typically higher initial and long-term cost, primarily due to pump requirements.
- Difficult to use variable water flow, as spray characteristics may be negatively affected.
