Fan arrays have long been a staple in the air movement industry. They offer a solution for replacing aging fans, particularly in spaces where large fan or motor replacements are not feasible. Fan arrays are also critical in mission-critical applications where redundancy is essential.
However, despite their advantages, traditional fan arrays present several challenges. These include the complexity of installation and control systems, as well as the lack of certified testing for airflow performance, sound, and vibration.
The presentation will also provide an overview of the design, fabrication, and commissioning of a large AMCA flow measurement tunnel for fan arrays. The industry needs and specifications will be discussed, along with flexibility requirements to cover a range of fan array test configurations. A unique control logic for fan arrays, developed for this application, will be reviewed, allowing the tunnel to operate over a broad range of flow rates up to 70,000 CFM.
