Selection of an air Handling Unit is a time
consuming procedure for any professional design engineer witch usually includes
among others the following :
-
Size selection based on various
variables including air flow and face velocity
-
Decision of the unit configuration
based on space dimensions as well as components required
-
Selection of all relative
components included in the unit such as Fans, Motors,
Drive-sets, Cooling/Heating coils, Recovery sections, filters,
Sound attenuators ect…
-
Fully dimensioned drawings of the
unit
-
Checks for available space in the
mechanical room either for positioning of the unit or for duct
connections.
-
And many more…
To cater for the diverse requirements of the international market,
Interklima has developed a unique AHU casing construction that
allows for many configurations and component options.
As an example, you may want a vertical standing double skin casing
with a front horizontal discharge.
This describes some of your requirements but as you go into more
detail about the filter plenum, electric heater bank and humidifier
section you start to realize the limitations of a simple paper
catalogue.
It is now much easier to choose the convenient air-handling unit
with the help of the Interklima AHU SELECTION software program
designed by the Interklima research and development engineering
department.
The Interklima AHU Selection software program is an excellent and
user-friendly tool, helping the engineers to run previously time
consuming and complicated selection procedures in only a few
minutes.
The Interklima AHU selection software program simplifies the
complexity of any given design and minimizes the time required for
its selection completion.
Some of the features of the Interklima AHU selection program are
-
Size selection through face
velocity of the air
-
Selection of cooling and heating,
water or evaporator, coils with a presentation of on/off air
conditions on the psychometric chart.
-
Using air – flow and external
static pressure, the detailed drawing of in FRONT and Plan View
can be appeared through some simple “clicks” of a p/c mouse,
which defines the components required.
-
Creation of detailed drawings with
unit configuration, marking the components to be included from a
existing list
All the main components that need to be
selected for an AHU are included in the selection procedure such as:
-
Fans (forward, backward, airfoil or
plug fans)
-
Motors (2,5,6,8 [poles single or
double speed).
-
Relative drive sets based on
airflow and total static pressure, with a presentation of the
resulting operating point on the characteristic fan curves
-
Cooling coils
-
Heating coil
-
Recovery systems (plate heat
exchangers, or thermal wheels, run around coils or
Heat pipes will be added soon.).
-
Sound attenuators (including noise
regeneration calculation).
-
Humidifiers
-
Filters
In every project, the user can
customize the general technical input such as pressure drop, outside
air conditions, inside air conditions, and coil properties. This way
there is no need to set the same parameters for every air-handling
unit separately under the same project.
Users can save any selection using a
great variety of parameters (Country - Area – City, project name or
category etc), which gives a great flexibility to recall it and have
a full statistic analysis of their work.
Results can be either printed or e –
mailed in *.PDF format.
Drawings can be reformed in *.DXF
format which allows the user, to transfer them on the mechanical
room, drawing, through AUTOCAD® . |
