What type of system delivers a constant temperature using low-velocity ductwork?

A constant air-volume system is designed to deliver a consistent airflow to a space, which allows it to maintain a uniform temperature. This system operates by delivering a fixed volume of air to the conditioned space regardless of the temperature demands. The low-velocity ductwork used in this system is beneficial for several reasons, including reduced noise levels and the ability to minimize energy consumption while still effectively distributing air throughout the space.

The system functions by regulating the temperature of a constant volume of air, which means that the heating or cooling capacity is modulated based on the thermal needs of the space. This ensures that the temperature remains stable and comfortable for occupants. In contrast, other systems, like variable-air-volume systems, adjust the airflow based on varying temperature needs, making them less suited for maintaining a constant temperature.

In other systems, such as dual-duct systems and terminal reheat systems, the approach to temperature control typically involves more complexities and variations in airflow, thereby making the constant air-volume system the most straightforward method for delivering a stable temperature using low-velocity ductwork.
