Success story made at the General Enrique Mosconi International Airport in Argentina.
By Johnson Controls
Considered a strategic airport in the Patagonian region and being among the busiest, general Enrique Mosconi International Airport, acts as an Area Control Center (ACC) in Comodoro Rivadavia, province of Chubut, Argentine Republic covering from the south of Viedma and Bariloche, including Antarctica.
It owes its name to Enrique Mosconi, who was an Argentine military and civil engineer, known mainly for having been a pioneer in the organization of oil exploration and exploitation in Argentina, as well as an ideologue and first president of the state company Yacimientos Petrolíferos Fiscales.
The new Comodoro Rivadavia terminal is the first in Argentina certified under the international LEED standard of sustainable architecture, and allows the simultaneous operation of up to four flights; This new building has 6,000 square meters, 3 luggage belts, 12 check-in counters, 2 sleeves, international pre-boarding and cabotage sectors that will operate simultaneously, service area and subsoil of technical cores.
During the bidding process of the different technologies involved for this new terminal, the company Elecris S.R.L. was awarded the supply and commissioning of the control systems and BMS (Building Management System) of the airport. Elecris S.R.L., as ABCS (Authorized Specialist for Building Control) of Johnson Controls, developed the project under the Facility Explorer brand.
Breaking the schemes
The great challenge of this facility is to be able to control and operate the systems that serve the airport efficiently and allow to reach the efficiency levels required by the LEED regulations, for its Ground Floor with an effective area of 3750 m2 and its Upper Floor with an effective area of 2750 m².
To carry out the control and monitoring of the systems, Elecris SRL installed the Johnson Controls Facility Explorer BMS solution, with a distributed architecture, having an FX-Server installed on a client server, connected to the same Ethernet backbone of the FX80 Supervisor. Downstream, at the field level, a series of FX-PCG programmable field controllers are installed with FX-PCX expansions located on two control boards, to which signals from sensors located in the field, contacts of electrical panels and in turn start equipment start commands arrive.
All drivers are connected to the FX80; it is equipped with six communication ports: 4 dedicated to Bacnet MS/TP Fieldbus, and the rest to integrations via Modbus RTU.
In the FX-Server reside the histories, schedules, alarms and graphic screens, functioning in turn as a Web Server, allowing access to the user through Web Browser from any PC that is on the same network.
Results
With the intelligent control system that was installed throughout the Airport, it will be possible to control and monitor the different variables for their best performance; each operator tracks the system through the screens and generates histories and alarms according to the parameters of the system.
On the home screen, the operator accesses the Energy, Lighting, Air Conditioning, VRF (Variable Refrigerant Flow), Fire, Sleeve and Services systems. All systems are divided by floors, this facilitates the operator's movement over the different menus and submenus of each system.
On the other hand, for the monitoring and control of carbon dioxide levels in the air conditioning, the operator can visualize these parameters in each area from different floor views of the airport. The system also allows access to the operation data of each HVAC equipment to see its operation modes, alarms and make set-point changes.
With this innovative system, the states of the main and sectional switches, voltages, failures are visualized; also having access to the Power Multimeters, transfer PLC, etc. and the physical location of the main lighting boards and also accessing the lighting command boards. It has all the data of the commands and states of the different elements that compose it.
The essential airport systems installed are as follows:
1. HVAC System:
• Rooftop Units.
• VRF System
• UpS and system room equipment
• Ventilations.
• Air curtains
• CO2 measurements in environments.
• Temperature and humidity measurements in environments.
2. Lighting system:
• Lighting (on/off) in sectional lighting boards.
• Measurement of light intensity level in environment.
3. Power system:
• Measurement of electrical parameters.
• Electrical transfers group/network of the distribution board. Integration with transfer PLC via Modbus.
• Switch states and temperatures of electrical transformers.
• Medium voltage cells, switches and disconnector states, integration with energy mulimeters.
• Integration of generator sets via Modbus.
• Integration of UPS via Modbus.
4. Ancillary systems:
• Elevators, monitoring of states and failures.
• Escalator, monitoring of statuses and failures.
• Drinking water, condition monitoring and failures of pressurizing pumps, cistern level.
• Sewage and rainwater pumps, monitoring of operating status.
• Integration with the fire detection system.
• Passenger Sleeves.
• Baggage belts
