Utility System Performance Studies
Cooling Tower Performance Assessment — Approach, Range & Heat-Rejection Efficiency Evaluation
Field-measured cooling-tower performance assessment — approach, range, water flow, fan performance and operating condition — to identify exactly where your cooling tower is underperforming and why.
What This Assessment Covers
A cooling-tower performance assessment measures how effectively the tower is rejecting heat under actual operating conditions.
It's particularly useful where condenser-water temperature is increasing, chiller kW/TR is deteriorating, cooling performance changes seasonally or the tower has not been independently assessed for an extended period.
Symptoms That Indicate Degraded Performance
- High condenser-water temperature
- Increasing chiller kW/TR
- High cooling-tower approach
- Fans operating continuously
- Reduced cooling performance
- Visible scaling or fouling
- Uneven water distribution
What You Get From the Study
Common Findings
Cooling-tower performance can deteriorate due to fill degradation, scaling, poor water distribution, inadequate airflow, fan-operation issues or changes in operating conditions. The assessment identifies which of these — or which combination — is affecting your tower and potentially the connected cooling system.
Who This Is For
Utility managers, HVAC heads and energy managers operating cooling towers for chillers, HVAC systems or industrial process cooling.
Frequently Asked Questions
Why is cooling-tower approach important?
Approach provides an indication of how effectively the tower is transferring heat under the prevailing ambient and operating conditions.
Does the assessment include the chiller?
Where relevant, the relationship between cooling-tower and chiller performance is reviewed because condenser-water conditions directly influence chiller efficiency.
Can cooling-tower fan energy be assessed?
Yes. Fan operating performance can be evaluated along with the tower's thermal performance.
Benchmark: cooling tower approach
Key indicators: Approach • Range • Wet-bulb temperature • Heat rejection
Actual performance depends on tower design, ambient conditions, water flow and operating load.
