Low-GWP refrigeration using carbon dioxide
CO₂ is fast becoming the preferred refrigerant in Food Retail applications and Danfoss is leading the way towards the adoption of CO₂. With the implementation of refrigerant regulations like the Kigali amendment to the Montreal Protocol (Global) and F-gas regulative (Europe), the quest for alternative solutions is accelerating even further and CO₂ is now recognized as the most viable and efficient solution among natural refrigerants in Food Retail applications.
Danfoss has pioneered CO₂ technologies for both trans-critical and sub-critical systems for more than ten years and has gained valuable experience from thousands of installations all over the world. The many installations have proved that CO₂ can be applied in supermarkets enabling both environmentally friendly and energy saving systems in all types of stores.

Russia’s first transcritical CO₂ hypermarket
In Voskresensk, Russian retailer Magnit has opened the first hypermarket in Russia using a transcritical booster refrigeration system with carbon dioxide (CO₂) — an eco-friendly and natural refrigerant.
Italy's largest hypermarket opts for CO₂ refrigeration
The use of transcritical CO₂ refrigeration in warm climates has been a hot topic for many years. In Milan, the 10,000 m2 brand new Iper market is a pioneer in transcritical CO₂ refrigeration systems using ejector technology to enhance efficiency in temperatures up to 38 °C.
A case study on ejector efficiency based on four test sites
The F-gas regulation in Europe and similar legislation in other parts of the world push for low-GWP solutions in food retail refrigeration. CO₂ is proving to be one of the most efficient low-GWP refrigerants thanks to the unique properties of the gas combined with technological discoveries that pave the way for optimum utilization of these properties.
CO₂ energy efficiency in supermarkets
Interest in carbon dioxide (CO₂) as a refrigerant in food retail applications has never been more intense than it is today and as such, there has been a lot of discussion with regards to the energy efficiency of these systems. The energy discussion is focused on two factors: climate change performance and financial justification.
What’s your response to refrigerant legislation?
All over the world, the phase-down of conventional HFCs in food retail applications has become the center of attention in the effort to combat climate change. Most recently, at the meetings of the parties under the Montreal protocol in Dubai where qualitative global phase-down of HFCs was agreed with a target of quantifying the details in 2016.
Making the case for CO₂ refrigeration in warm climates
In this article, we will explore the pros and cons of different solutions for CO₂ refrigeration in warmer climates – from basic cascade systems to the advanced ejector technology.
