Abstract: Monitoring airflows through fan arrays and adjusting fan speeds during air handling system operations to dynamically provide and/or maintain balanced discharge airflows. An air handling system controller utilizes fan speed and airflow data values of each fan array to determine whether a fan speed setpoint of the fans of a fan array should be increased or decreased in order to balance the airflow through each fan array. When an increase or decrease in the fan speed setpoint is required, the controller adjusts the fan speeds accordingly. Monitoring airflows through fan arrays and adjusting fan speeds during air handling system operations to dynamically provide and/or maintain balanced discharge airflows. An air handling system controller utilizes fan speed and airflow data values of each fan array to determine ...more ...less
