WHAT ARE THE ISSUES ?
![Page 13: Ian tuena (1) nrc presentation hpe2016](https://reader033.vdocumento.com/reader033/viewer/2022042723/587da7531a28ab22148b7fa7/html5/thumbnails/13.jpg)
• 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

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
![Page 26: Ian tuena (1) nrc presentation hpe2016](https://reader033.vdocumento.com/reader033/viewer/2022042723/587da7531a28ab22148b7fa7/html5/thumbnails/26.jpg)
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
