Best practice Policymaking: The Australian Refrigeration Association stirs up the Federal Department of the Environment
The Australian Refrigeration Association (ARA) is preparing its third submission to the Federal Department of the Environment regarding the Review of the Ozone Protection and Synthetic Greenhouse Gases Management Act (OPSGG MA). In its previous 2 submissions, ARA was supported by over 70 of the leading cooling and refrigeration organizations. Now ARA is calling upon the public to show its support for the third submission. The submissions focuses on the reduced use of hydrofluorocarbon (HFC) refrigerants. ARA estimates that the transition to natural refrigerants may reduce the cost of HVACR services in Australia by up to $10 B per annum, and reduce national GHG emissions by 7%. ARA is encouraging individuals to write a unique response about why they believe the Federal Department of Environment should prioritize this thematic. The key recommendations include: Banning the use of HFC’s in new vapour compression systems with a charge >5 kg by 2025. Compulsory use of low GWP refrigerants in all new vapour compression systems with a charge <0.150 kg by 2025. The introduction of a series of mechanisms to deliver minimum energy efficiency benchmarking, skills based refrigeration licensing (as opposed to refrigerant based licensing), alignment of WH&S legislation making state and federal WH&S legislation nationally consistent. …
Best practice Product: Ice by night, air-conditioning by day: the TSU-C/D ice thermal storage
The TSU-C/D ice thermal storage unit by the Baltimore Aircoil Company (BAC) provides a constant near-freezing water (1-2 °C) supply for applications such as food processing, breweries and dairies at the lowest first cost. The external melt system of the TSU-C/D unit stores cooling as ice when cooling demand and/or energy rates are low (mostly overnight), and releases cooling for air-conditioning when cooling demand and/or energy rates are high (usually daytime). As the TSU-C/D forms ice overnight when electricity costs are cheapest and condensing temperatures are lowest, operational costs as well as the carbon footprint are lowered. As with all BAC cooling towers, the TSU-C/D model is independently certified by the Cooling Technology Institute (CTI), hereby ensuring that published thermal capacities reflect actual thermal performance. This eliminates the need for customers to perform costly individual cooling tower testing. …
Best practice Product: Save water with the new HXI-HXV closed circuit cooling tower!
The patented flow control system of the HXI – HXV hybrid closed circuit cooling tower by the Baltimore Aircoil Company (BAC) is the ideal solution for medium to large heating, ventilation, and air conditioning (HVAC) and industrial applications. Unparalleled water and cost savings, adaptability to dry, adiabatic or combined wet-dry operation as well as no plume discharge make the HXI – HXV hybrid closed circuit cooling tower by the Baltimore Aircoil Company (BAC) ideal for a range of applications. The patented intelligent flow control system with a 3-way valve allows customers to remarkably reduce annual water consumption (by up to 70%). Depending on local water costs, the flow control system alone can pay for the HXI – HVX hybrid unit in as little as two years. As with all BAC cooling towers, the HXI – HXV model is independently certified by the Cooling Technology Institute (CTI), hereby ensuring that published thermal capacities reflect actual thermal performance. This eliminates the need for customers to perform costly individual cooling tower testing. …

The energy regulator will be the Department of Petroleum and Energy. …
Best practice Product: Open-drive screw compressors for ammonia application
Bitzer’s open-drive screw compressor series OSKA is ideal for use in large-scale commercial and industrial ammonia refrigeration and air conditioning systems. With a high cooling capacity, the OSKA series may be used on its own or in parallel operation with several compressors and shared oil separator in industrial applications. The combination of open compressor and external standard motors make the series exceptionally flexible and allows operation at different supply voltages. A significant improvement to the new series is the separation between the refrigerant circuit and electrical drive, greatly facilitating maintenance and repair. Further improvements include large volume flows of up to 1,015 m3/h at 2,900 revolutions per minute, integrated control electronics and an optimized slider concept for seamlessly adjustable capacity control. …
Best practice Product: Reciprocating compressor for subcritical CO2 application
Bitzer’s OCTAGON SL series of semi hermetic reciprocating compressors have cooling capacities ranging from 2.7 and 80 kW (–35° C/–5° C) for different subcritical applications. Bitzer’s CO2 compressors have been boasting with an efficient suction gas-cooled motor, high-quality valve plates, wear-resistant drive gears as well as adjustable capacity control since 1988. The OCTAGON SL compressor series offers improved energy efficiency, and the application limits were pushed to a higher condensing temperature whilst the admissible pressure load was expanded on the high and low-pressure side (53/30 bar). …
Best practice Success story: Air conditioning for world’s largest female-only university in Saudi Arabia
CAREL’s evaporative ChillBooster accommodates comfortable learning conditions in the world’s largest female-only university, the Princess Nora bint Abdulrahman University in Riyadh, Saudi Arabia. The ChillBooster is an evaporative cooler which cools air and lowers its average condensing pressure before the air is used by the condensing units such as chillers or dry coolers. Spontaneous evaporation is favored by the atomization of water in micrometric droplets, reducing the thermal energy required for evaporation from the surrounding air. Having opened in May 2011, the Princess Nora bint Abdulrahman University has a capacity of 50,000 students and hugely promotes female education. The ChillBooster guarantees a higher absorption ratio and less hygiene problems compared to the appliances typically used in such situations. …
