Title: Improving Cooling Tower Performance Through Proper Operation and Maintenance
To review basic cooling tower operations, the necessary maintenance needed to minimize common deficiencies and the associated impacts on thermal performance.
• Review the basic types of cooling towers and how they operate
• Discuss suggested maintenance and deficiencies that can occur in a cooling tower over time.
• Explain thermal characteristics of a cooling tower and the impact poor operations or deficiencies will have on tower performance.
This presentation will review the overall lifecycle of a cooling tower from a mechanical perspective. There are different types of cooling towers ranging from field erected fiberglass towers to factory assembled steel towers. These will be explored and explained in how they are applied in the marketplace. The basic operation of a cooling tower will be broken down and each subsystem reviewed to give the audience a summary of basic cooling tower operations. This will allow for detailed explanations of cooling tower components and how they contribute to the overall cooling tower performance. Both the initial design of a tower and the after-market upgrades will be reviewed. Recommended annual maintenance and the associated deficiencies that commonly develop over time will be discussed in combination with the implications of water treatment issues. Variability in tower configurations, fill types, and material selection will be presented as well as the impacts these have on tower operation and life expectancy. In closing, cooling Tower performance will be reviewed and the associated impact of deferred maintenance and known mechanical deficiencies will be explained from the perspective of lost cooling tower capacity and efficiency. Understanding the mechanical and operational impacts is critical when consulting customers on cooling tower operation.
