Leading
ventilation manufacturer Airflow Developments has added Variable Air
Volume (VAV) dampers to its Duplexvent range of commercial Mechanical
Ventilation with Heat Recovery (MVHR) units. The VAV systems
constantly monitor the air volume supplied and share this information
with the ventilation unit. As such, the systems ensure optimum air
quality and comfort by allowing the ventilation to respond
effectively to the demands of each area of the building.
Commercial
buildings such as offices, schools, hospitals and retail environments
should utilise Mechanical Ventilation with Heat Recovery (MVHR)
technology to protect the building fabric, as well as ensure
occupants are benefitting from healthy, fresh air and a comfortable
indoor climate.
However,
with many centralised MVHR systems the ventilation rate remains the
same in each room regardless of changes in occupancy levels,
temperature or humidity. This means that constant human intervention
is needed to deliver the correct air flow at the required system
pressure.
Variable
Air Volume (VAV) dampers offer a solution because they control the
flow of air to each zone of the building in response to changes in
demand. This helps to maintain a consistently high quality indoor air
environment. The
VAV dampers fitted to the Duplexvent range constantly monitor the air
volume passing through the system and send this information to the
centralised ventilation unit.
The
communication between each damper and the central unit allows the
MVHR system to increase or decrease the flow rate quickly and
efficiently based on the demand. When used in conjunction with
humidity or CO2
sensors, these dampers can automatically adjust the ventilation based
on the usage or occupancy of that room, independent of the other
areas within the building. Airflow’s VAV system also provides the
option of manual adjustment for applications where the user requires
a level of control.
“Indoor
air quality is increasingly being recognised as a key factor for
health and wellbeing but the reality is that ventilation requirements
can vary significantly across different areas of a building and at
different times of the day,” said Krzysztof Kwarciak, Category
Product Manager at Airflow Developments. “The latest development to
our Duplexvent range, the VAV dampers system, ensure our MVHR units
can respond swiftly and effectively to these changes in demand.”
