The new automatic ventilation controller (AVC) from Arens International coordinates
the ventilation of multiple rooms or zones by simultaneously controlling up to
eight additional zone controllers.
The Arens automatic ventilation controller works by sending signals to
windows to open or close depending upon factors such as the season, time of
day, rain, wind speed and internal and external temperatures. Offering one of
the highest levels of functionality in the Arens range of ventilation
controllers, the new AVC can be integrated with building management systems.
Some of the key benefits of Arens automatic ventilation controllers include
providing automatic natural ventilation, while also allowing occupants to
manually operate windows in each room; operating characteristics adaptable to
season, day of week, hours of the day or even school term dates; and ability to
be integrated with building management systems or other control systems within
the building such as HVAC, fire, security and lighting.
AVCs are used for natural ventilation in different types of buildings
and operate on the basis of information gathered from the wind, rain, and internal
and external temperature sensors to open or close windows and maximise occupant
comfort. An AVC allows night purging to be programmed for hot air to escape
from the building and be replaced by cooler air during pre-set hours of the
The Arens automatic ventilation controller can be integrated with HVAC
systems to signal the windows to close when the HVAC system begins to operate.
Similarly, when integrated with fire alarm systems, the AVC will open or close
windows on receiving a fire signal. The AVC can also be integrated with
security and REED switch systems to trigger the alarm if the windows are
operated when the security system is on.
Arens automatic ventilation controllers can be adapted to suit the needs
of specific project requirements and applications. For instance, operating
characteristics are fully adaptable according to the season, day or time; features
such as night purging, sensor limits, actuator stroke, hours of operation and
integration can all be configured to suit the project; the AVC can operate
independent of, or be integrated with a building management system; and the
controller can be installed in various building types such as office buildings,
schools, universities, community centres/halls and aged care centres.
Arens automatic ventilation controllers have been installed at Padua
College, Tyabb Campus; Arbourlea Children’s and Family Centre, Cranbourne North;
Kilvington Grammar Middle School, Ormond; and Parkdale Intergenerational
Community Hub, Parkdale.
