High efficiency cooling solution with CO2 as a refrigerant for supermarkets in all climate zones

With the EU’s F-Gas Regulation’s HFC phase-down and global warming potential (GWP) limit of 2500 as of 2020 in new stationary refrigeration systems, high GWP refrigerants such as the HFC R-404A have come increasingly under pressure. In addition, in several European countries, HFC refrigeration systems are subject to high taxes, which are often based on the GWP of the refrigerant. One of the main areas of application of such high GWP refrigerants are supermarkets. For that reason, there is a high penetration of CO2 as a refrigerant in this particular market segment. However, to be attractive in all climate zones, the CO2 technology needs to overcome the challenges of the “CO2 efficiency equator line”, meaning that energy efficiency must also be ensured in countries where the average temperature exceeds 15°C.

  • Carrier CO2OLtec® Evo, a transcritical CO2 refrigeration system designed with patented modulating ejector technology and a CO2 pump
  • CO2 as a non-flammable and non-ozone depleting refrigerant with a GWP of just 1 (compared to for example R-404A which has a GWP of 3922)
  • Performant in any type of climate and adaptable to all types of installations, both for commercial and industrial applications, from 50 to 1,300 kW MT
  • Possibility to choose optional features / modules to further increase the energy efficiency and fulfil other functions such as heat recovery, heat pump and air-conditioning operation.

  • High efficiency solution reducing annual energy consumption by 30% compared to an average 2012/2013 store
  • Reduction of the operational cost due to energy savings
  • Long-term sustainable low GWP refrigerant solution which is not targeted by the HFC phase-down
