At what branch pressure would maximum heating occur to the damper motor?

• A. 10 psig
• B. 13 psig
• C. 15 psig
• D. 20 psig

Answer: (B)

The correct choice is 13 psig because this level of branch pressure is typically where the system is optimized to deliver maximum energy to the damper motor without causing excess heating. In control systems, particularly those involving dampers and motors, there's a relationship between pressure, flow, and the power delivered to the actuator. Each damper motor is designed to operate efficiently within a specific pressure range, with 13 psig being the ideal point where it achieves the best balance of performance and energy consumption. Operating at this pressure allows for adequate force to be exerted by the motor to adjust the dampers effectively, while minimizing the risk of overheating due to excessive pressure. Higher pressures, such as 15 psig or 20 psig, may lead to increased energy consumption and potential overheating, as the motor may be subjected to greater stresses than it was designed to manage continuously. Therefore, while the motor can handle various pressures, 13 psig is optimized for ensuring maximum heating efficiency without jeopardizing the longevity and reliability of the damper motor.
