ISO 22044:2021

Overview

ISO 22044:2021 - Commercial beverage coolers - Classification, requirements and test conditions - provides a standardized framework for classification, construction requirements, and test methods for commercial beverage coolers with integral refrigeration systems. It defines types, parts, physical dimensions and performance-related terms, and sets out laboratory and field test conditions to evaluate product safety, durability, thermal performance and energy use. This standard is not applicable to remote or secondary system cabinets.

Key topics and technical requirements

• Scope and applicability

  • Applies to refrigerated cabinets designed to chill and display pre-packaged, non-perishable beverages with integral refrigeration.
  • Not applicable to remote and secondary system cabinets.

• Classification of types

  • Vertical (overall height 0.5 m to 2.2 m), semi-vertical (≤1.5 m, vertical or inclined opening), horizontal (top access).
  • Open vs closed cabinets (open: no access barrier; closed: door or lid).

• Parts and dimensions

  • Defined components: air discharge, air return, shelf, base deck, night cover, front.
  • Key metrics: net volume, gross volume, equivalent volume (Veq), total display area (TDA), load limit, load limit line, footprint, height/width/depth.
  • Example: refrigerated shelf area requires ≥125 mm vertical clearance above shelf.

• Construction and safety

  • Materials, thermal insulation, refrigerating system and electrical component requirements are specified.
  • Normative references include ISO 817 (refrigerants), ISO 5149-2 and IEC 60335 series for safety.

• Test programme

  • Tests outside and inside a controlled test room: door/lid seal and durability, dimensional checks, M-can based temperature tests, loading procedures, running-in and stable condition criteria.
  • Performance tests include water vapour condensation, lighting tests, and calculation of specific energy consumption (SEC).
  • Test reporting, marking (load limit, rating plate) and manufacturer information requirements are included.

Practical applications - who uses ISO 22044:2021

• Manufacturers developing and certifying commercial beverage coolers to meet uniform performance and safety criteria.
• Test laboratories conducting reproducible tests (M-can procedures, SEC, lighting).
• Retailers and specifiers selecting cabinets based on net volume, TDA and energy performance.
• Regulators and procurement teams ensuring compliance with energy/ecodesign requirements.
• Design and R&D teams benchmarking insulation, airflow and display designs.
