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.

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.

ADAP-KOOL®automatically adapts to changes in the operating environment, delivering optimized refrigeration performance and energy efficiency. They provide advanced algorithms, supervisory control and monitoring.

Danfoss has pioneered two control algorithms that help you to 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.

As food retailers look to reduce energy bills, every incremental savings counts. Increasing price competition means operating costs have an immediate impact on competitiveness and profitability—and, after staff, energy is the biggest bill most supermarkets have.
