Smart Airport

Airports are, like living beings, in constant movement,
adapting their facilities and creating new services
according to the needs of their passengers.


Airports function to meet the needs of passenger mobility.
The objective is to offer the passenger the best experience
during their journey.
Smart Airport

Smart Airport: Existing airports have to interconnect
their systems, to be able to adapt and respond to
specific requirements at any time.

Thousands of passengers are using
these services daily to move around

“AVOID DISCOMFORT”
The Passenger
Our main goal is to supply the best passenger experience
The Passenger SATISFACTION produces Passenger LOYALTY.
A comfortable atmosphere from
the Terminal to the Aircraft is
necessary for an enjoyable journey.
The Comfort
Thermal comfort is the state of mind that expresses
satisfaction with the thermal environment and is assessed by
subjective evaluation (ANSI/ASHRAE Standard 55).
Maintaining this standard of thermal comfort for occupants of
buildings or other enclosures is one of the important goals of
HVAC design engineers.

The Comfort
GLOBAL COMFORT: From arrival to departures
Due to the fact that all airport zones are different in volume,
use and occupancy… to achieve a sense of comfort in all
areas, combined with low energy consumption, it is necessary
to have smart air conditioning with high versatility and
accurate measures of control.
The Comfort

The heat load in an aircraft cons ists of 4 components:
Occupancy loads
Conduction loads
Solar loads
Electrical loads

What cooling air do we need ?
Psensible (Kw)= Qm x C x (aircraft inlet T° - cabin T°)
with:
- Qm = mass air flow in Kg/s
(Note: In PCA business, most of the time the flow is in Kg/min)
- C = specific heat of air: 1 KJ/(kg x °C)
- Aircraft inlet Temperature °C
(Note: unit discharge T° + loss or gain of T° in the ducting),
- Cabin Temperature °C
SMART PCA
SMART PCA: An air conditioning unit for maintain the quality
of the air inside the aircraft cabin interrelating external
parameters such as Aircraft model, environmental conditions,
installation and specific airport characteristics.
