What is the maximum temperature for air conducted through flexible air ducts and connectors?

The maximum temperature for air conducted through flexible air ducts and connectors is established to ensure safety and effectiveness in HVAC systems. In this context, the correct answer is 121°C.

This temperature limit is important because exceeding it can lead to degradation of the materials used in the flexible ducts, potentially causing them to weaken or fail. Additionally, higher temperatures can increase the risk of fire hazards and may affect the overall performance of the air distribution system. Maintaining air temperatures within prescribed limits helps ensure efficiency and longevity in HVAC operations, while also adhering to the safety guidelines set forth in mechanical codes.

Recognizing these temperature limits is crucial for HVAC professionals to make informed choices regarding materials and design, thus ensuring compliance with industry standards and the safety of both the system and the occupants it serves.
