CO₂ in food retail

The supermarket aktiv & irma in Oldenburg, Germany, has pressed the start-button to a solution enabling it to store and generate electricity. The grocery store’s manager calls it a leap forward in energy supply. Danfoss and SMA have helped make it happen. Learn how.

A stronger environmental profile and energy savings of approx. 30% from a cooling solution that can be expanded as needed. These are the results so far for Danish organic food company Aarstiderne. Since Q1 2018, the company’s facilities at Barritskov, Denmark, have relied on a CO₂ cooling system with Danfoss components delivered by refrigeration installer company JF Køleteknik A/S.

How can refrigeration professionals comply with the EU F-gas regulation? What technologies can be used to make the transition to compliant refrigerants? And how can professionals specify, install, service, and use these solutions? Innovation and new approaches require know-how, and Danfoss is offering extensive, user-centric content that builds know-how through training, education, and the sharing of knowledge with the company’s partners, customers, and other stakeholders such as policymakers on several platforms.

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.

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.
