Why refrigerants are a hot climate issue

By Vaidehi Shah

Australian companies can save billions on energy bills and cut cooling-related emissions by half if they switch away from synthetic hydrofluorocarbon (HFC) refrigerants to natural ones such as carbon dioxide and ammonia, said industry leaders on Tuesday.

Refrigerants are fluids that absorb and release heat in heating, ventilation, air conditioning and refrigeration (HVACR) systems used in homes, commercial buildings and industrial facilities across the world.

Speaking at the Australian Refrigeration Association’s (ARA) HVACR Energy Efficiency Seminar at the Australian Technology Park in Sydney, ARA president Tim Edwards told the 40-strong audience that “natural (refrigerants) are better in every way and yet, synthetics continue to dominate the industry”.

The most recent study on this by the Australian Department of the Environment in 2012 shows that about 43,500 tonnes of synthetic refrigerants such as HFCs or hydroflurochlorocarbons, or HCFCs, are stored in refrigeration and air conditioning equipment in the country. This volume of stored gas is known as a gas bank.
