The drivers to change in commercial refrigeration and the solutions.

1. PROVIDING NATURAL
REFRIGERATION SOLUTIONS FOR
AUSTRALIAN INDUSTRY

2. Why The Need
for change?

3. “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.

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

5. The refrigeration
industry is
adapting to this
change.

6. • Only uses Natural
substances as a
refrigerant
1
• Typical GWP of 1
• ( R404a= 3922)
2
• Less expensive average
$7 kg3
Natural Benefits over HFC Systems

7. Energy Efficient
Future Proof

8. Our Objectives

9. Typical solution using a Advansor CO2 Transcritical Booster
System

10. Small HC chilled water ? system on
a flower farm

11. Innovative Scan Pack Low charge NH3
System

12. WHAT ARE THE
ISSUES ?

13. • 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

14. Case examples
• Typical installations
• Large Supermarket
• Large/Medium
• Smaller convenience store

15. Case Study • ‘Big Box’ Store (Typical)

– Smaller pipework saves materials AND labour
• Further possible savings with a holistic
building approach

26. 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

27. 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
