AIRAH Awards finalists – Excellence in Refrigeration

In the lead-up to the AIRAH Awards gala dinner on November 15, HVAC&R News is profiling finalists in some of the different categories.

The AIRAH Awards recognise excellence and achievement within HVAC&R, with initial nominations coming from those working within the industry. Click here to see all the finalists for the 2018 awards.

For the first time, the AIRAH Awards includes an Excellence in Refrigeration category. This award recognises excellence in the retrofit or upgrade to existing refrigeration systems or the development of new systems. It also commends outstanding work in service delivery. Products are not eligible in this category and nominated projects must have been commissioned within the past three years.

The finalists for 2018 are:


Cold Logic – Coopers Brewery

Coopers new facility at Regency Park in Adelaide represents the single biggest investment in the company’s 155-year history and is considered the most technically advanced maltings in the world. Getting the refrigeration right was, understandably, vital. Cold Logic achieved this by bringing a state-of-the-art ammonia refrigeration system capable of providing 3600kWr of chilled water to various stages of the malting process.

“The system was integrated with the overall maltings plant control system provided by Coopers and significant time was spent optimising following commissioning to achieve the best possible energy efficiency and robustness available,” says Dr Michael Riese from Cold Logic. “During the installation phase, extensive communication and planning together with the main parties ensured a seamless build process.”


Glaciem Cooling – The Bend Motorsport Park

The Bend Motorsport Park in South Australia demonstrates a significant advancement in refrigeration technology, combining thermal energy storage (TES) and R744 (CO2) systems with unique features.

The TES system uses a newly developed phase change material (PCM) that freezers and melts at -6°C, enabling cooling of between 0–2°C. The new coil design and dynamic melt system incorporated in the TES tank increases the thermal efficiency of the PCM, allowing more than 85 per cent of the latent heat stored to be extracted. The charging of the PCM is controlled by a cloud-based forecasting algorithm.

The R744 system has been integrated with indirect cooling technology. It is the result of extensive R&D carried out by Glaciem in conjunction with the Barbara Hardy Institute at UniSA.


Heatcraft + Goff’s Refrigeration – Optus Stadium

This project in Perth encompassed the design, engineering and installation of leading refrigeration technologies to service Optus Stadium’s extensive cold chain requirements. Equipment specifications evolved throughout the project, adding complexity and requiring Heatcraft Australia and Goff’s Refrigeration to adapt and accommodate. They overcame project challenges with a national approach, harnessing the full strength of the Heatcraft technical and sales support team.

“Optus Stadium features the latest innovation in design, construction and technology and has made its mark as one of Australia’s top sporting and entertainment venues,” says Heatcraft’s Elizabeth Paparo, Affil.AIRAH. “The project team demonstrated excellence in refrigeration delivering an entirely customised solution designed to achieve TEWI reductions of 48 per cent and energy savings of 3 per cent compared to conventional refrigeration system design.”
