Digital Air Volume (DAV) System (Terminal System Manager)

Carrier's Digital Air Volume (DAV) System offers completely integrated control of Air Terminal Units. Using DAV, the operation of self-contained Units or Air Handlers is automatically adjusted to meet a zone's heating and cooling requirements. The Carrier Comfort Network provides the communicating link between the HVAC equipment to maintain the DAV System's integrated system operation and performance.

Zone-Directed Control - Unlike traditional HVAC systems which push hot or cold air to a zone regardless of it's actual requirements, a DAV System enables the Air Terminals to continuously monitor space temperature and activate equipment to pull heating or cooling to a space based on zone demand, resulting in more precise comfort control, lower energy costs and extended equipment life. By providing the vital link between the temperature zone and the air source, the DAV System monitors and controls air temperature, humidity and air volume, which can dramatically improve overall indoor air quality.

System Control Strategies - The DAV System's closed loop control allows dynamic equipment response to changing space conditions, minimizing inefficiencies. This feedback enables each piece of equipment to automatically adjust its operation to effectively match the building load.

When DAV is applied to carrier equipment with Product Integrated Controls, the following control strategies may be employed to optimize the efficiency and enhance occupant comfort:
