When operating duct systems, what must be monitored to ensure safety and compliance?

Monitoring temperature limits in duct systems is crucial for several reasons. First, temperature affects the efficiency of the HVAC system; if temperatures exceed certain thresholds, it can lead to equipment malfunction, energy waste, and reduced comfort levels.

Additionally, elevated temperatures can pose safety risks, including the potential for thermal damage to the duct materials or associated components. For example, certain materials used in ductwork can degrade or become hazardous if exposed to temperatures that exceed their ratings.

Moreover, maintaining proper temperature limits helps ensure compliance with building codes and regulations, which often specify temperature thresholds to prevent issues like condensation, which can lead to mold growth or structural damage.

While monitoring air velocity, duct material types, and installation procedures is also important, temperature monitoring has a direct impact on the safety of operation and efficiency of the system, making it a primary focus in ensuring compliance within duct systems.
