FAQ – Reducing Energy Consumption in Refrigerated Display Cabinets

Refrigerated display cabinets, including devices with direct sales functions (such as showcases and refrigerated cabinets in stores), consume a significant amount of energy. Therefore, they are central to EU regulations concerning ecodesign and energy efficiency. Compliance with current regulations not only ensures the legality of selling and using these devices but also helps reduce operational costs and CO₂ emissions.

1. Install Cold Store Doors – “Closing” Open Refrigerated Display Cabinets

For open refrigerated display cabinets, the simplest step yielding the greatest energy savings is installing refrigerated doors. This “closing” of the cabinet (known as a retrofit) can reduce energy consumption by up to 50%.

Regulatory and Normative Dimension:

• According to Commission Regulation (EU) 2019/2024, refrigerated display cabinets with direct sales functions must meet a specific Energy Efficiency Index (EEI). Installing doors significantly improves this index.​
• Since September 1, 2023, stricter EEI thresholds apply (e.g., EEI ≤ 80 for most devices), making door installation necessary to maintain compliance.​
• This action also supports the objectives of the Energy Efficiency Directive (2023/1791/EU) – the obligation for large enterprises (e.g., retail chains) to reduce final energy consumption by 1.49% annually.​
• It also aligns with circular economy principles – modernization instead of replacing the entire device.​

It’s worth noting that retrofit solutions are available as compatible door systems that can be easily integrated into existing equipment without the need for replacement.

2. Use Components Compliant with Ecodesign – Not Just an Obligation, but Real Savings

According to Regulation (EU) 2019/2024, all commercial refrigeration equipment with direct sales functions must meet a specific EEI level. Since 2023, stricter requirements apply (e.g., EEI ≤ 80 for most cabinets). This necessitates the use of more energy-efficient components, including:

• Electric motors of at least IE3 class (in accordance with Regulation (EU) 2019/1781 and EN 60034-30-1),​
• EC (electronically commutated) fans and fan motors – with higher efficiency and lower energy consumption, compliant with EN ISO 12759 and Regulation (EU) 327/2011 / 2024/1834,​
• Condensers and refrigeration units with high COP, compliant with PN-EN 13215,​
• Compressors certified according to PN-EN 12900, allowing easy comparison of their performance and optimization of consumption.​

3. Use High-Efficiency LED Lighting

In refrigerated display cabinets, LEDs not only enhance product presentation but also impact electricity consumption. Therefore, they must comply with:

• Regulation 2019/2020 (ecodesign for light sources) – requirements concerning efficiency (lm/W) and flicker limitations,​
• EN 62471 – photobiological safety,​
• EN 60598 / EN 60335 – requirements for luminaires and power supplies.​

Modern LED modules and power supplies with energy efficiency certifications (e.g., Class VI) allow for energy consumption reduction compared to traditional fluorescent lighting.

4. Maintain Sealing – Gaskets, Doors, Hygiene

Often overlooked, door gaskets and insulation play a crucial role in maintaining temperature and reducing energy losses.

• Gaskets must be tested for aging (EN 14285), durability, and tightness,​
• Glass doors compliant with EN 12150 and EN 12600 ensure safety and good insulation properties,​
• Components in contact with food must comply with EU Regulation 1935/2004 and hygiene standards (e.g., EN 1672-2),​
• Use of self-closing hinges to prevent doors from being left open.​

IMPORTANT! Regular maintenance (cleaning the condenser, gaskets, checking for leaks) can reduce electricity consumption by several percent and prevent potential failures.
