Top information about Cooling Towers

A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers, rely solely on air to cool the working fluid to near the dry-bulb air temperature.

The crossflow cooling tower belongs to the family of mechanical drift cooling towers in which the upward flow of the air cools down the hot water raining down from the hot water basin at the top onto the cold water water basin at the bottom. see more

The Counterflow Cooling Tower

The counterflow cooling tower is a type of cooling tower designs that offers the maximum thermal performance for its area of occupation. The fill media is horizontally installed beneath the hot water distribution basin, and the cooling process is carried out as the air passes through the fill absorbing the heat from the water flowing down the fill.

In a counterflow design, the air flow is directly opposite to the water flow. Air flow first enters an open area beneath 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. see more

Crossflow vs Counterflow Cooling Towers

Data center thermal optimization is a comprehensive package of facility improvement measures—from the cooling tower to the rack—which optimizes primary/secondary cooling cycles and white space. It applies intelligence about the density of IT workloads to regulate the cooling within a data center.

Comparing crossflow vs counterflow cooling towers is a common thing to do when choosing between cooling towers for a specific application. The most apparent distinction between crossflow towers and counterflow towers is that the airflow is perpendicularly contacted with the process water in the fill in the former while it comes into contact with the process water stream in the opposite direction for the latter.
