Case studies
A busy Danish supermarket reduced its annual heating bill by 89.7% and its CO₂ footprint by 6.7 tons a year by making use of the waste heat from its refrigeration system.
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.
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.
Danfoss offers a complete portfolio of gas and liquid ejectors that provide significant benefits in CO2 refrigeration applications. Here we take a closer look at these offerings: the Multi Ejector Low Pressure (LP), the Multi Ejector High Pressure (HP), and the Liquid Ejector (LE). All three ejector products are only available as a complete Multi Ejector Solution™ where the ejector is bundled with the AK-PC 782A pack controller to provide the robust system controls necessary for efficient and reliable operation.
Danfoss has pioneered two control algorithms that help you achieve this balance. The Minimum Stable Superheat (MSS) algorithm has been an important part of the Danfoss ADAP-KOOL® offering for years and is still the ideal choice for adaptive evaporator control for dry expansion. Now Danfoss introduces the next generation: Adaptive Liquid Control (ALC).
Intelligent control solutions are important for achieving reliable, optimized operation and realizing financial savings and environmental
benefits in your transcritical CO2 refrigeration solution.

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.
Around the world, there is little doubt that CO2 is fast becoming food retailers’ refrigerant of choice. At Danfoss alone, we’re currently seeing supermarkets switching to CO2 refrigeration systems at a rate of around 10,000 a year—and that number is growing fast.
When you stop and think about it, it’s a little strange that supermarkets usually pay to heat their premises and water while their refrigeration system works overtime to move heat energy outside.
If you work in facilities or energy management for a food retailer, change is something you handle every day. When the way we live, work, or shop changes, new food retail technology is close behind.
In the last few years, supermarkets have made great advances in energy efficiency—reducing both overhead and their environmental impact.
Reducing energy use is valuable, and always will be. But there’s another side to reducing energy costs. Increasingly, the biggest potential saving isn’t only in using less energy; it’s in optimizing how it’s used, and when.
Many new kinds of store facility technologies promise to help. Big data, automation, and the Internet of Things (IoT) all have the potential to save food retailers time, money, and energy, while preventing food waste.
