PROVIDING NATURAL REFRIGERATION SOLUTIONS FOR

AUSTRALIAN INDUSTRY

Why The Need for change?

“The era of procrastination, of half measures, of soothing and baffling expedience of delays, is coming to its close. In its place we are entering a period of consequences.” Winston Churchill.

The world is moving toward a more sustainable future driven by the concept of climate change, increasing energy costs and renewable energy.

The refrigeration industry is adapting to this change.

• Only uses Natural substances as a refrigerant

1

• Typical GWP of 1 • ( R404a= 3922) 2

• Less expensive average $7 kg 3

Natural Benefits over HFC Systems

Energy Efficient Future Proof

Our Objectives • Technology

– Leading Edge – Advansor are #1 in Europe – Scan Pack NH3 Low charge Proven Track record in Australia – We are buying proven systems

• Training – NRC to provide Advansor training to customer staff – NRC to promote Training in Natural refrigerant systems – Hydro carbon Ammonia CO2

• Policies – Meeting current and predicted future legislation

• (i.e. COP21 Climate Conference in Paris)

• Benefits – Very good energy savings – end user has “Green Credentials”

WHAT ARE THE ISSUES ?

• Poor knowledge within the Consulting and Engineering Fraternity

within Australia for Natural Refrigerant Solutions

• Poor Options offered to end users further training and technical

education is required ie: Bangarang Sydney

• Lack of skilled staff for initial commissioning and ongoing

maintenance for new plant

• Conflicting and restrictive State and Federal regulations

• Lazy solutions provide poor outcomes

• Poor Understanding by state emergency response providers

Case examples

• Typical installations • Large Supermarket • Large/Medium • Smaller convenience store

Case Study • ‘Big Box’ Store (Typical)

• Annual Simulation performed

• Location: Melbourne • Equipment Ambient

Design Temp.: 43°C • Parallel Compresson

Transcritical CO2 system provides Est.

– 5.7% Energy Savings as compared to Standard Transcritical Booster System

– 20.4% Energy Savings as compared to R134a/CO2 Cascade System

Simulations for Australian Cities

• Energy Savings Projections • Parallel Transcritical vs. R134a/CO2 Cascade

– Melbourne – 20.4 to 21.0% – Sydney – 7.1 to 9.3% – Brisbane – 3.0 to 5.7% – Adelaide – 14.4 to 14.8% – Canberra – 23 to 23.5% – Perth – 9.2 to 10.6% – Darwin – 1.5 to 2.8%

Further Possible Savings

• Est. 6-8% Savings with Adiabatic Cooling on Gas Cooler

• Savings on initial investment (‘1st Cost’) – Cheaper refrigerant – Only 1 Rack – Smaller pipework saves materials AND labour

• Further possible savings with a holistic building approach

A Holistic Approach to Retailers

• Ability to provide hot water reclaim due to efficient use of higher condensing temperatures – Heating Hot Water – Domestic Hot Water

• High cost saving by applying store comfort cooling – Chilled Water Cooling – NH3 solutions – Hydrocarbon solutions

• Smart control systems at both trading floor and plant utilized to best advantage

Distinct advantages of Good design

• Lower Energy costs • Future Proof • Lower Maintenance costs • Better whole of Life costs • Socially responsible • You make the transition ONCE
