At what temperature should ducting be insulated?

• A. Over 20℃
• B. Over 30℃
• C. Over 40℃
• D. Over 50℃

Answer: (C)

Ducting should be insulated when it is operating at a temperature exceeding 40℃. Insulating ductwork is essential to maintain energy efficiency and prevent heat loss or gain, as well as to protect personnel from burns or hazards associated with high temperatures. When ducting exceeds this temperature threshold, the insulation helps reduce heat transfer to the surrounding environment, which is particularly important in systems where energy efficiency is a priority. Insulation also helps to minimize condensation on the duct's surface, which can occur when warm air comes into contact with cold surfaces. Maintaining a temperature below 40℃ in the ducting prevents condensation-related issues and the potential for mold or corrosion. In summary, insulating ducting above 40℃ is crucial for energy conservation, operational efficiency, and safety within power engineering systems.
