Fan Systems IV: Improving System Efficiency

Problems such as unusually high operating and maintenance costs, poor airflow delivery, surges or noise or wear on the electrical components can be caused by oversized fans, poor system design, poor balancing or leakage, or wasteful airflow control practices. Often, users are only concerned with initial cost, accepting the lowest bid for a component, while ignoring system efficiency. To achieve optimum fan system economics, users should select equipment based on life-cycle economics and operate and maintain the equipment for peak performance. This course helps define opportunities to improve fan system performance by identifying common fan problems. We'll also uncover why a highly efficient fan system is not merely a system with an energy-efficient motor.
