It is an odourless, colourless fluid that is heavier than air and which has been used as a refrigerant for over a century. Even though CO<sub>2<\/sub>\u00a0is necessary for life on earth, it is also a Greenhouse Gas (GHG) that can modify the environment if its concentration in the atmosphere increases significantly. This refrigerant is classified by the RSIF as \u201cSafety Class = A1\u201d, i.e., it is \u201c<strong>non-flammable<\/strong>\u201d and has a \u201c<strong>low toxicity<\/strong>\u201d.<\/p><p>CO<sub>2<\/sub>\u00a0was used as an early refrigerant before freons, but it quickly fell out of use due to its more complex technology. It has excellent thermo-physical properties, although it poses difficulties due to its low critical temperature value (30.978\u00b0C) and its high pressures. It has a much higher volumetric capacity than conventional refrigerants.\u00a0<strong>When used for refrigeration applications at ambient temperatures below approx. 25\u00b0C, it performs at the subcritical cycle, while it performs at the transcritical cycle at higher temperatures.<\/strong>\u00a0It is worth mentioning that, in the case of transcritical systems, work efficiency rates similar to those of conventional fluids require the use of complex cycles (parallel compressor, mechanical subcooling, ejectors, etc.).<\/p><p><strong>This gas has a high thermal conductivity and a high density in its gaseous phase, leading to a good transfer of heat in evaporators, condensers and gas coolers;<\/strong>\u00a0therefore, these properties allow smaller units to be selected when compared to those using CFC, HCFC and HFC.
