There are two general types of duct systems: single-duct and dual-duct. Each type can be used in both constant- and variable-flow applications.

Dampers direct and control airflow through the air distribution system. They can also be installed in certain fire-rated walls or floors for life-safety to prevent the migration of fire and smoke. These motorized units are typically controlled by the fire-alarm system but recent advances in the reliability of direct-digital-control (DDC) systems have allowed the HVAC …

Coils are heat exchangers that transfer energy between the supply-air stream and the energy-transport medium: water, steam, or refrigerant. Most coils are made of copper tubing arranged in rows, specifically designed for the amount of energy transfer required. They may be bare tubes when differential temperatures are high, or have extended fins
Fans move air by pushing it with impellers (blades) powered by a motor. Pushing the air increases pressure which is measured in inches of water. As the air is pressurized, it is heated by friction as it passes through the fan. More heat is added if the fan motor is located in the air stream. …
