CO2 : HVAC applications in commercial buildings
Oatmill Cinema Complex, located in Mount Gambier, South Australia, is a typical example of a commercial building with ageing HVAC infrastructure. The HVAC equipment is over 20 years old and operates on ozone depleting refrigerant, R22. The high operating and maintenance cost of the HVAC equipment has led the owners to refit the HVAC plant.
For HVAC end users, replacing aging R22 equipment is a daunting task as many of the options offer no real future proofing. In Australia, the use of carbon dioxide (R744) systems has generally been confined to supermarket, food process and cold storage applications. Its application in commercial building HVAC has always been deemed unrealistic. The Oatmill Cinema project aims to demonstrate that R744 is a real, viable option for replacing aging R22 HVAC equipment – not only offering longevity, but also substantial operational savings of up to 40 per cent.
