Steril-Aire EmittersTM are helping Auckland International Airport achieve its energy saving and sustainability policies

In 2009 a detailed energy audit of the international terminal building revealed some significant cost and carbon savings could be achieved with a simple payback of less than two years. Over the next twelve to eighteen months an energy efficiency programme will see technologies installed including:

‘UV C cleaning of coils improving the efficiency of the whole heating, ventilation and air conditioning system’

The combined impact of the technologies will achieve a reduction of energy costs of over 20% and a reduction in Auckland Airport's total carbon footprint of over 10%.

standard feature and those that do not have it may be upgraded.

Operationally the main difference between MLAT and ADS-B is that MLAT is limited in range and will generally be used within a control zone or terminal airspace. Coverage for ADS-B, on the other hand, can range up to 250NM and only one ground station is required because the aircraft position is derived from the aircraft’s GNSS data. In essence the two technologies complement each other.

There is no intention to amend controlled airspace to require the carriage of ADS-B capable systems at this time however it is something that is worth considering if a new aircraft is being imported.

MLAT and ADS-B work in mountainous areas because of the multiple ground stations that the aircraft data can be sent to. The ground stations are positioned to minimise any shielding by mountain peaks. The new installations can be deployed with minimal environmental impact, solar-powered if necessary, and are capable of withstanding extreme environmental conditions.

Air Traffic Controllers will be able to provide pilots with more accurate and timely traffic information and confirm that pilots are where they say they are. Advantages for the pilots are greater ATC efficiency and aircraft position confirmation.

Surveillance is a word usually associated with being audited or

undergoing spot checks by a regulator. Some adjustment in perception may be required as the word is becoming commonplace when talking about airspace and Air Traffic Control. It is being used to describe the surveillance carried out by the new technologies that directly assist the pilot rather than just inform the Air Traffic Controller.

This shift in emphasis (form traditional radar systems) began with transponders, or Secondary Surveillance Radar (SSR). Collision avoidance systems are another example as is the use of ADS-B for aircraft to be able to ‘talk’ to each other to exchange position and track information.

THERE’S A STRANGE BLUE LIGHT IN THE PLANT ROOMS! Martin Fryer, Auckland International Airport

On 11th May 2010 Auckland Airport, in conjunction with Steril-Aire and Econ-Air installed a trial Ultra Violet C (UVC) sterilization system into an airhandling unit. The Steril-Aire emitters bathe the face of the coil in UVC light, keeping the coil free of bio-film and mould, which enables the system to run at its utmost efficiency, reducing energy costs, maintenance costs and improving indoor air quality.

The technology is new to New Zealand airports but is widely used in sterile applications such as hospitals and laboratories. The installation is just one recommendation, from a detailed energy audit undertaken in 2009, being implemented by Auckland Airport over the next eighteen months.

Martin Fryer, Sustainability Advisor (pictured) said “This is a real win-win for Auckland Airport, reduced energy costs, reduced carbon footprint and improved air quality for our passengers and tenants. This project is part of a much wider energy efficiency programme that should see Auckland Airport save over 20% in energy costs and could reduce our total carbon footprint by over 10%”

The trial will last for two months and then the technology will be rolled out across the entire international terminal.

AHU T2-6 Study Results

Product Technology Overview

Steril-Aires world leading UVC technology provides multiple benefits with a short return on investment.

Energy Saving:

The biofilms that build up on the cooling and heating exchange plates (or fins) inhibit the heat transfer process and reduce the airflow.

Steril-Aire’s EmittersTM destroy these biofilms restoring and maintaining coils to their `as new’ performance and efficiency. Typical savings are 15-20% but 30-40% savings have been achieved.

Maintenance Savings:

By destroying the biofilm and organic build up on the cooling coils Steril-Aires EmittersTM eliminate the need for manual cleaning and chemical usage. Coils, drain pans and plenums stay free of mould and bacteria.

Duct cleaning can also be eliminated (depending on the severity of contamination) as the cooling coils and drain pans are the food source for the mould that grows downstream in the duct work. The high output UVC EmittersTM destroy the food source so the mould in the duct work starves and dies.

Other maintenance benefits include free flowing drain pans and drain lines (no slime/algae build up) and removal of odours caused by the mould growing in the ducts and also odours created within the building.

Health:

Steril-Aire’s EmittersTM will eliminate up to 99.9% of airborne viruses and bacteria and other microbes, significantly improving indoor air quality (IAQ). Provide staff and passengers protection against future pandemics. Steril-Aires high output UVC is very effective against viruses such as flu strains, SARS, pneumonia, TB (incl new super strains recorded around Australasia) and the common cold. Reduced allergy and asthma symptoms triggered by biofilm and mould. Independent studies have shown 60% reductions in Hospital Acquired Infections, 50% reduction in school staff absenteeism and improved productivity when using Steril-Aire UVC Emitters.



Sustainability:

This can be achieved in many ways with the use of Steril-Aires EmittersTM:

Sterilises the condensate water from the drain pans allowing it to be recycled at a high quality level. An example is to use as make-up water in cooling towers, resulting in a reduction in water and chemical consumption.

Reducing chemicals used within the building

Reduce Ozone created within the building from photo copiers, furniture etc

Extending the life of the air conditioning equipment by restoring and keeping components and interior surfaces clean and free of mould and organics containing moisture causing corrosion and degredation.

A simple effective way of reducing carbon footprint with so many other benefits.

Study Objectives To show significant performance improvements:

Visual difference in cleanliness of cooling/heating coils and drain pans

Efficiency improvement from better coil heat transfer resulting in a 10-20% energy reduction

Improved Indoor Air Quality

Reduction in mould growth within system

Produce clean condensate water suitable for recycling

Return on Investment in under 2-Years

Tests to be conducted before and after UVC installation:

Wet and Dry Bulb temperatures before and after cooling coil

Heating/Cooling coil pressure drop

Airflow/velocity readings

Coil and drain pan surface contact plates

Photos (Pre and Post UVC)

Using the above data, AHU manufacturers design performance and basic HVAC guidelines from ASHRAE/AIRAH we can calculate efficiency improvements.



AHU T2-6 Test Results Manufacturer: York YCC 50 X 60 7100 l/s Pre Testing Date: 26/04/10 Post Testing Date: 19/07/10

Testing for AHU-T2-6 included:

AHU entering and leaving Temperature (wet and dry bulb) using data loggers

Airflow at AHU supply duct sample points using a Hot Wire anemometer. Readings taken as a mean average over 30 seconds at each point (filters removed).

Pressure drop across the cooling coil using a Magnehelic gauge (filters removed).

Rodac contact plates used for checking before and after microbial counts on cooling coils and drain pans.

Each testing period is carried out with the system at 100%. Chilled water valve at 100% open. Outside air dampers closed and return air 100% open. Note: Heating Coil is bolted directly onto the Cooling coil. There is no access to Cooling Coil air off side or Heating Coil air on side for manual cleaning.

Cooling Coil Pressure drop:

Coil Pressure Drop Reduction 20%

The reduction in static pressure shows that the UVC is destroying the build-up of biofilm between the Heating and Cooling fins. Less restriction means more airflow and better heat transfer.
