Although CO2 operates with high pressures, it is an excellent refrigerant in terms of efficiency and environmental impact. CO2 system technology has been widely adopted in Europe, Australia and is gaining in popularity in the USA. Adapting CO2 systems in warm climates can be a challenge, however advances in technology are enabling engineers to [...]
Temperatures 0⁰C and above Traditionally CO2 has only been used in low temperature applications however Glaciem's DP-CO2 system enables it to be used efficiently in medium temperature and air conditioning applications. Temperatures -18⁰C –to -25⁰C CO2 used in applications between -18⁰C to -25⁰C demonstrates an increase in energy efficiency >20% when compared [...]
In 2017 the Australian Federal Government amended the Synthetic Greenhouse Gas Management Legislation to include the phase out of HFC refrigerants. A statutory 85 per cent phase-down of HFC imports commenced on the 1 January 2018. The phase-down will have a starting point of 8 Mt CO₂-e, based on Australia’s current demand and reduce [...]
HFO refrigerants are been developed as a replacement for HFC refrigerants. Their operating characteristics are very similar to the HFC’s they’re intended to replace. The chemical process to manufacture HFO is extremely complex raising questions about the eventual cost per Kg. There are also concerns relating to their environmental impact, as when HFO’s breakdown [...]
When installed with the appropriate safeguards, ammonia is an extremely efficient refrigerant, especially in large industrial applications. Ammonia however, is toxic and flammable and has been at the centre of a number of unfortunate incidents which have led to loss of life. This has raised serious concerns about the suitability of large charge ammonia [...]
