What type of fan is most commonly used in ducted air conditioning systems?
AI Explanation
The correct answer is B) Centrifugal fan.
Centrifugal fans are the most commonly used type of fan in ducted air conditioning systems. This is because centrifugal fans are well-suited for the high-pressure requirements of air conditioning ductwork, as they can generate the necessary airflow and static pressure to move air effectively through the system.
The other options, such as propeller fans (A), vane-axial fans (C), and tube-axial fans (D), are not as commonly used in ducted air conditioning systems, as they are generally better suited for lower-pressure applications or have design characteristics that make them less efficient or effective for the specific needs of air conditioning ductwork.
