Case studies
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.
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.
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.
