Cycle of Concentration Explained

Understanding the cycle of concentration is vital for HVAC professionals working with boilers and cooling towers. This key concept directly impacts water treatment, system efficiency, and operational costs.

What is Cycle of Concentration?

In simple terms, the cycle of concentration (CoC) refers to the ratio of dissolved solids, typically measured by chlorides, in the water of a system compared to the incoming makeup water. Specifically, in a boiler system, it is the ratio of chlorides in the boiler water to those in the feedwater. For cooling towers, it is the ratio of chlorides in the recirculating water to those in the makeup water.

Importance of Cycle of Concentration

Maintaining the correct cycle of concentration is critical for several reasons:

• Water Treatment Efficiency: A higher cycle of concentration allows for better efficiency in water treatment processes. By recycling more of the water and reducing the quantity of makeup water, HVAC systems can minimize the chemical treatment needed, thus lowering operational costs.
• Corrosion Reduction: Elevated levels of chlorides can lead to increased corrosion potential within pipes and equipment. Understanding and managing the cycle of concentration helps protect HVAC systems and extends their lifespan.
• Environmental Impact: By optimizing the use of water and chemicals, professionals can significantly reduce the environmental footprint of HVAC operations, aligning with sustainability goals.

Calculating Cycle of Concentration

To calculate the cycle of concentration, HVAC professionals can use the following formula:

CoC = Chlorides in system water / Chlorides in makeup water

Regular monitoring and analysis of both boiler water and cooling tower water are necessary to ensure the ratios remain within optimal ranges.

Best Practices

To effectively manage cycle of concentration in your HVAC systems, consider these best practices:

• Implement regular water testing to monitor chloride levels.
• Utilize automated controls to manage makeup water and recirculating water efficiently.
• Work with water treatment specialists to ensure the right chemicals are used to maintain water quality.

Conclusion

In conclusion, a solid understanding of the cycle of concentration is essential for HVAC professionals involved in boiler and cooling tower operations. By monitoring and optimizing this crucial ratio, you can enhance system performance, reduce costs, and contribute to environmental sustainability.
