Before digging into the secret of Danfoss adaptive defrost, let’s first take a look at the most common methods of defrosting refrigerated display cases, and why they’re necessary.

Use this list to learn what goes into making an efficient walk-in cooler or freezer.

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.

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.

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.

The heat reclaim potential depends on the climate conditions, and so far CO₂ refrigeration with heat reclaim has mostly been applied in colder climates. Read more.
