SUMMARY • Smart Airport • The Passenger • The Comfort • PCA System • Smart PCA
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. SERVICE IMPROVEMENT AIRPORT MANAGEMENT ANALYSIS OF INFORMATION ENERGY SAVING ISO 50001 - Energy management
ThePassenger The Passenger, the most important airport user Thousands of passengers are using these services daily to move around for business, for work, for pleasure Heavy Baggage Large Queue Suffer for Tiredness Races along the hall “AVOID DISCOMFORT”
ThePassenger Our main goal is to supply the best passenger experience The PassengerSATISFACTION 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 HVACdesign engineers.
TheComfort Factors influencing thermal comfort • Air temperature • Operative temperature • Relative humidity • Metabolic rate • Clothing insulation • Mean radiant temperature • Air speed
TheComfort 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.
TheComfort • Passenger Comfort in Boarding Bridges • The last step before boarding the aircraft (Stress) • High Solar radiation • High gradient of temperature (infiltrations) • Air speed
TheComfort • Passenger Comfort inside the Aircraft • Maintain constant the same level of passenger Comfort between boarding and disembarking. • High OccupancyLatent Capacity High Humidity • ANSI/ASHRAE Standard 161-2007 Air Quality within Commercial Aircraft Cabin Pressure Air temperature Humidity Air Speed Ventilation Ozone Bleed Air contaminant Monitoring Addressing Contamination Events Measurements for specific Variables

PCA system • 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 Losses Distribution 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 istsof 4 components: Occupancyloads Conductionloads Solarloads Electricalloads 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 PCA system
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
SMART PCA Smart PCA CONTROL • Must be able to manage all internal parameters for supply really that is demanded. • Must be able to manage all external parameters that are taking part of the system: • Airport Building Management System • Maintenance systems • Passenger Boarding Bridges • Flexible Hose retriever • Pits system • 400Hz • Visual Docking Guidance
SAMART BLOWER SYSTEM • Measure and guarantee the correct supplied airflow. • Reduce the energy consumption • Adapt itself to the installation losses
SMART PCA SMART COMPRESSIVE SYSTEM • Guarantee the Cooling Capacity demanded by the system. • Flexible components for adjusting itself to the demand. • Inverter compressors with oil level management integrated. • EC Axial fans • Electronic expansion valve. • Improve efficiency (Save Energy). • Improve the reliability. Directive2009/28/CE ENERGIA RENOVABLE
SMART PCA SMART PCA MAINTENANCE • Failure analysis • Electrical consumption measurement • High Reliability design for a long life time • Ramp VISOR PRO: Maintenance Supervision Software • 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
