Supermarket refrigeration must protect food quality while controlling energy, cost and carbon impact. Defrost sits at the center of that challenge. It ranks among the most energy-intensive processes in store operations, yet many systems still rely on blind timers or end-defrost temperature methods. These approaches often run too long, overheat display cases and put unnecessary stress on products, equipment and energy budgets.
Isabel Janke and Paolo Chiaramonte will present a practical control innovation that changes how defrost cycles end. Instead of guessing when ice has cleared, the algorithm detects the exact point when ice disappears from the evaporator. It tracks real-time thermodynamic behavior and identifies the transition from latent heat exchange, when ice melts, back to sen ...
