Flow control strategies are used to regulate the air delivery of fans according to system demand, thereby improving energy efficiency and reducing power consumption. One of the most common methods is throttling using dampers or valves. Although simple and inexpensive, this method reduces airflow by creating resistance, which leads to energy losses and lower overall efficiency. Variable Frequency Drives (VFDs) are one of the most effective flow control strategies. By varying the speed of the fan motor, VFDs adjust airflow to match actual requirements. Since fan power
