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.

ACA is the carbon management certification for airports.

The Passenger

The Passenger, the most important airport user

Thousands of passengers are using these services daily to move around for business, for work, for pleasure

“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

Passenger Comfort in Boarding Bridges The last step before boarding the aircraft (Stress) High Solar radiation High gradient of temperature (infiltrations) Air speed

The Comfort

Passenger Comfort inside the Aircraft Maintain constant the same level of passenger Comfort between boarding and disembarking. High Occupancy Latent Capacity High Humidity

Energy Balance

Aircraft Heat Loads (kW)Internal Loads caused by Occupancy, Conduction,

Solar and Electrical loads.Depending on the inlet TºC it determines the airflow

LossesDistribution losses such

as ducts, hoses…)

PCA Capacity (kW)Net Cooling Capacity: the unit has to reduce the temperature from

the ambient air to supply the same airflow at the

required outlet temperature

The heat load in an aircraft cons ists of 4 components:

Occupancy loadsConduction loadsSolar loadsElectrical loads

PCA system

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.

Manage the systems during the operation.• Adjustment depending on the external factors• Analyze Consumptions and costs • Optimize the system for improvement the

performance.• Improve the Reliability of the system

Availability (Ai) Availability is in fact the probability that a

component will be available for operate in a determinate time. Taking in consideration the unavailability time due to its proper faults.

CONCLUSION

CIAT SMART SOLUTION The CIAT Smart PCA has been developed for

covering the most airports exigencies.

The CIAT Smart PCA is able to adapt itself to the demand increasing the features, increasing the efficiency, increasing the reliability and reducing the pay off.

The CIAT Smart PCA guarantee the Passenger Comfort inside the Aircraft
