WinTADS
WinTADS AHU works from basic
principles and rules allowing 'custom' air
handling units to be designed. Standard unit
sizes may be entered, but height, width and
length can be varied in steps to a minimum of
one millimetre. The system displays information
allowing the operator to make the optimum
selection based on the job's individual
requirements. McQuay International has used
Computair software for a number of years to
design their Vision, rooftop and energy
recovery units.
The operator builds up the air
handler pictorially using colour coded icons
which illustrate whether the information
concerning the component has been entered or
the component has been selected. The system
error checks all entries to ensure a viable
unit has been designed. Complex designs such as
double deck, side by side and bypass units are
catered for.
The component selections are
calculated from fundamentals. Psychrometric
validation and prediction is included and a
chart showing the conditions through the whole
unit can be displayed. Where possible,
equipment vendors own selection methods are
utilised to ensure complete technical and
financial compatibility. The system calculates
the performance, cost, weight, length and air
pressure drop for each component, all of which
can be displayed using the Quick View
facility.
Once designed, the unit can be
sectioned for transportation or site access by
using the scale representation. By this stage
the complete make up of the unit is determined
and a utility is included to allow the operator
to view the panel and mullion layout. Material
costing and labour times are also derived from
fundamentals giving the engineer vital
information during the design stage.
The software is generated using
C++ and is compatible with all Windows®
operating systems after Windows® 95. All the
hard copy outputs are generated with Microsoft®
Word® utilising the flexibility of a word
processor together with the capability of
personalising a document.
The benefits of computerisation
are well known - speed of response, accuracy,
reproducibility, reduced overheads and an
increased attention to detail. Great care is
taken with the software to ensure that these
benefits are not at the expense of commercial
acumen and flexibility of design.
