Description of the DEMO: To reach a high level of sustainability and resilient cooling goals, EEV application, full parallel system design, and defrost optimisation are promising technologies.
With the recent update of the eco-design domestic energy labelling system (A-G labels), the average energy consumption in the domestic refrigerator market is projected to decrease by up to 30% by 2025. To contribute to this goal, Demo 13 explores innovative technologies and control strategies to enhance household refrigerator energy efficiency. The demonstrator integrates multiple advancements:
Prototype evaluations have confirmed a 10% reduction in energy consumption, with ongoing refinements targeting even greater efficiency. These results are crucial for designing high-energy-efficiency class refrigerators in line with updated regulatory requirements.
