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:
Using the Carrier Comfort Network or the PIC front end in your DAV application provides easy access to valuable system information:
