7-Eleven Kuala Lumpur
Case Study
This project was a conversion from HCFC-22. It involved a Topaire air-cooled split unit. Energy savings are reportedly 24% over the conventional, synthetic-based system.
Commercial / Industrial Air Conditioning
Commercial air-conditioning usually relies on the use of large chillers to distribute cooled water around a building. Cool technologies used in commercial air-conditioning usually involve ammonia for larger chillers and hydrocarbons and carbon dioxide for smaller chillers.
A combination of energy efficiency measures and natural refrigerants
could reduce total global emissions from air-conditioning by 40%-60%.
ABN Amro
Case Study
The Dutch bank ABN Amro, uses a CO2 system to cool 15 high-performance servers at the data centre of its London branch. To provide a controlled climate for this hardware, the manufacturer, Star Refrigeration, designed and built a low-energy-consumption CO2 refrigeration system in 2006 to generate a total output of 300 kW. The carbon dioxide is recondensed with water at 6C via an indirect chilling cycle. The cooling is handled by ventilator units on the back of the server cabinets, where the carbon dioxide evaporates at 14C and absorbs the heat siphoned off by the fans. CO2 is reportedly well suited for IT climate control as it does not conduct electricity, helping to increase safety.

Angel Square
Case Study
In 2012, The Co-operative UK opened its headquarters in Manchester, UK, complete with the largest propane chiller to be installed in a commercial building in the country. The Angel Square complex features eight 650 kW water-cooled water chillers using R290, and achieved the highest possible ˜outstanding” accreditation under the BREEAM rating for sustainable building.
Ansell Co., Ltd.
Case Study
Ansell Co., Ltd. in Thailand is recording enery savings of 19.4% as a result of its conversion from an HCFC-22-based cooling system to 2 hydrocarbon split-systems. The system reportedly has a payback period of 12 months.
APEX Circuit (Thailand) Co., Ltd.
Case Study
APEX Circuit Co., Ltd., a circuit-board design and manufacturing company in Thailand, has reported energy savings of 13.2% as a result of its conversion from an HCFC-22-based system to 3 split-unit hydrocarbon-based systems manufactured by Trane.
Asahi Brewery
Case Study
Asahi Brewery aims to reach zero absolute greenhouse gas emissions by 2050. Their natural refrigerant journey began in 1999 with the installation of a co-generation energy system at their Nagoya plant, using ammonia absorption for air-conditioning and hydrocarbons for the beer vending machines. The company saved 400 million yen a year from the resultant energy savings.
