Advanced Ergonomic Technologies - AET Flexible Space
AET are leading experts in commercial office
underfloor air conditioning systems, having advised and overseen the
installation of over 25 million square feet throughout the world in a
wide variety of climatic conditions. The Hiross Flexible Space System, a
modular, standardised system has been the clear UK market leader for a
number of years and has a proven track record in use. With today’s
emphasis on reducing energy usage wherever possible, AET have now added
an all-air free cooling underfloor system called PleinAir to their
range. This variable air volume system includes a ground breaking
modulating damper to overcome the problem of the lack of air circulation
traditionally associated with VAV systems.
What is Hiross AET Underfloor Air Conditioning?
-
Sometimes called UFAD, underfloor air
distribution utilises the space beneath raised access flooring
(plenum), very often, but not exclusively in commercial office
operations
-
Air is supplied at floor level & may return
either through the floor or at high level
-
Underfloor air conditioning is most definitely
not a displacement system
Why Choose Underfloor Air Conditioning?
-
Only a very small increase in the space for the
distribution of power, data & telephones beneath the raised access
floor is necessary for inclusion of air distribution, so making more
efficient use of the building’s volume
-
Height saving over ceiling based systems either
in refurbishment or new construction because of the reduced need or
even abolition of ceiling ducting
-
Comfort levels are high with easy resolution of
any draught or overheating issues
-
Flexibility is ensured as air delivery is made
through easily relocatable raised access floor panels
-
Tax advantages are realised as the floor system
may be classed as Plant & Equipment, so attracting improved Capital
Allowances
-
Floor-based components are easily to fit
retrospectively in Shell & Core scenarios, so saving initial capital
expenditure
-
Architectural freedom in the ceiling is
guaranteed if there is no need for ceiling ducting
Operation of the Hiross Flexible Space System
-
Floor standing, super quiet air handling units
serve zones of 100-300m²
-
Silicone coated baffle material separates the
supply & return plena
-
Treated air is delivered into the supply plenum
-
Fan-assisted terminals supply air from the plenum
into the space above
-
They are connected only by power & data cabling –
there are no ducts
-
Local control may be tempered by centrally set
parameters
-
Adjacent users may control both airflow &
temperature
-
The system also facilitates central monitoring &
control
-
Spent air is drawn back into the return plenum
through grilles in the floor
-
Optional ceiling-return systems are available
-
Fresh air is introduced into the return air path
-
Air is cooled or warmed at the AHU by water
delivered from central plant
-
Riser requirements are minimal
-
Remote control optional
-
Anodised aluminium grilles are rectangular in
shape
Operation of the PleinAir System
-
Pressurised air may be supplied to the plenum by
central plant or local air handling units
-
100% free cooling using central station air
handling units
-
Air is returned at high level
-
In cooling mode, passive tile units (PTUs)
deliver air into the workspace
-
PTUs have unique time modulated air damper for
excellent throw
-
In heating mode, a fan-powered hot water or
electrical unit heats recirculated office air
-
Options for cooling only or heating/cooling PTUs
available
-
Wide variety of grille configurations, colours &
shapes
-
Both Variable and Constant volume tile units are
available
-
Local PTU control is an option
-
PTU connected only by power & data cabling –
there may be minimal ductwork in the plenum
-
Bacnet IP controls
AET would be delighted to discuss the comparisons and
advantages of either the Flexible Space or PleinAir systems for your
project.
