What is a common characteristic of a properly designed duct system?

A properly designed duct system is characterized by its ability to minimize air turbulence. When a duct system is designed effectively, it maintains smooth airflow that ensures air is distributed evenly throughout the space being conditioned. Turbulence can lead to inefficiencies in airflow and result in uneven heating or cooling, which is contrary to the goal of an HVAC system. By reducing turbulence, the system enhances energy efficiency, improves comfort levels, and can lead to quieter operation.

Minimizing turbulence involves various design considerations such as using appropriate duct sizes, ensuring smooth transitions between different duct sections, and avoiding sharp bends that could disrupt the airflow. In a well-designed duct system, the airflow is streamlined, promoting better overall performance and longevity of the HVAC system components.

The other factors mentioned, like maximizing static pressure or reducing duct size, may not necessarily lead to an optimal system performance and might introduce complications such as decreased airflow efficiency or increased energy consumption.
