Globus had an ambitious target: to open the new 25,000 square meter hypermarket using transcritical CO₂ for its refrigeration and heating. Danfoss helped KrioFrost—a Moscow-based refrigeration equipment producer and installer—to equip Globus’ huge new store in the Moscow suburb of Salaryevo with the company’s first transcritical CO₂ booster refrigeration system.

As part of the luxury shopping mall Paseo La Galeria, Danfoss has supplied a refrigeration control system for the supermarket “Superseis”, including systems management for better energy efficiency in the food refrigeration application.

The use of transcritical CO₂ refrigeration in warm climates has been a hot topic for years. In Milan, the brand new 10,000 m² Iper market is a pioneer in CO₂ refrigeration using ejector technology to enhance efficiency in temperatures up to 38 °C.

The F-gas regulation in Europe and similar legislation in other parts of the world push for low-GWP solutions in food retail refrigeration

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.

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.
