Overview

EN 14511-2:2022/FprA1 (CEN) defines test conditions used to rate air conditioners, liquid chilling packages, heat pumps for space heating and cooling, and process chillers with electrically driven compressors. The document applies to units using air, water or brine as heat transfer media and sets the conditions for declared performance data used for regulatory compliance and energy labelling.

This draft amendment (prA1) to Part 2 updates rating footnotes to address maximum flow rate handling in the referenced test tables. The standard supports consistent, reproducible performance declarations for both single duct and double duct units and aligns with EU Ecodesign (Regulation 206/2012) and Energy Labelling (Regulation 626/2011) requirements.

Key Topics

• Scope and applicability: Ratings for air-cooled, water/brine-cooled units and process chillers; electrically driven compressors; space heating/cooling and process applications.
• Test conditions: Standardised inlet/outlet temperatures, flow-rate handling and test arrangements to ensure comparable performance data across products.
• Performance declaration: Conditions under which manufacturers declare capacities, efficiencies and other performance metrics for Ecodesign and energy labelling.
• Amendment prA1 (February 2024): Clarifies that if a calculated flow rate exceeds a unit's maximum flow rate, the maximum flow rate shall be used together with the specified inlet or outlet temperature in the appropriate tables.
• Regulatory relationship: Informative Annex ZA links the standard to relevant EU legislation; the standard was prepared under a standardization request from the European Commission.

Applications

This standard is used by:

• Manufacturers preparing declared performance data for product fiche and energy labels.
• Test laboratories conducting type and rating tests for air conditioners, liquid chilling packages, heat pumps and process chillers.
• Certification bodies and regulators verifying compliance with Ecodesign and Energy Labelling rules.
• Specifiers and consultants comparing equipment performance for HVAC and process cooling projects.

Practical benefits include:

• Consistent rating methodology that improves comparability of equipment across markets.
• Clear guidance on flow-rate limits, reducing ambiguity when actual system flows exceed equipment limits.
• Support for regulatory compliance, streamlining the path to market within EU member states.

Related Standards

• EN 14511-1 (requirements and definitions) - scope linkage noted in EN 14511-2.
• EN 14511-3 and EN 14511-4 (additional parts covering measurement and performance reporting).
• Relevant Ecodesign and Energy Labelling regulations: Regulation 206/2012 and Regulation 626/2011 (as referenced for declared data).

For further details consult the full EN 14511-2:2022/prA1 document published by CEN/TC 113. The amendment is published in the three official languages (EN/FR/DE) and includes informative guidance on interaction with EU legislation.
