What is a true statement about the operation of induced draft cooling towers?

The statement that it is more economical to operate two fans at low speed than one fan at high speed is accurate and reflects an understanding of energy efficiency and operational cost management in cooling towers. Operating two fans at low speed can enhance the system's efficiency by distributing the workload across both fans, which results in lower energy consumption compared to running a single fan at high speed. This method also reduces wear and tear on the fans, prolonging their life and further contributing to cost savings over time. Additionally, using two fans can improve overall system reliability and allow for better temperature control within the cooling tower, enhancing its performance.

Maintaining a lower speed operation may also lead to lower noise levels, contributing to a more favorable working environment. The operational dynamics of induced draft cooling towers benefit from this rationale, ensuring effective circulation of air and cooling without incurring unnecessary energy costs.
