This guide explains how cross flow fans and axial fans work in HVAC systems, covering their design, airflow patterns and common applications in air conditioners, condensers, cooling towers and fan coil units. While fan selection depends on airflow and pressure requirements, system performance ultimately relies on the quality of the components inside them.
