Overview
EN 14511-2:2022 is the CEN standard that sets out test conditions for rating air conditioners, liquid chilling packages, heat pumps and process chillers with electrically driven compressors. It is Part 2 of the EN 14511 series and relies on Part 1 for terms and definitions. The document defines the environmental, electrical and rated operating conditions used to determine declared capacities, power input and efficiency figures required for Ecodesign and energy labelling compliance in the EU.
Key topics and requirements
- Scope of testing: Applies to units using air, water or brine as heat-transfer media and covers air-cooled and water(brine)-cooled process chillers. It includes single- and double-duct units and multisplit/modular systems.
- Environmental conditions: Specifies indoor and outdoor test envelopes (e.g., typical dry-bulb ranges such as 15 °C to 30 °C for many units) and wet-bulb requirements where applicable. Separate tables cover indoor-installed vs outdoor-installed units.
- Rating conditions: Detailed rating condition tables (Tables 3–25) prescribe inlet/outlet temperatures and test points for heating and cooling modes to determine rated capacity, power input, COP/EER and electrical consumption.
- Electrical supply: Manufacturers must declare voltage and frequency to be used during tests.
- Special cases: Rules for brine testing (use brine specified by manufacturer), evaporatively cooled condensers, calorimeter room testing (pressure equilibrium guidance, max 1.25 Pa difference) and variable-flow considerations are included.
- Regulatory alignment: Test conditions are structured to support compliance with EU regulations for ecodesign and energy labelling (referenced in the standard).
Applications - who uses it and why
- Manufacturers: To produce certified, comparable performance data and declare rated capacities and efficiencies for product literature and regulatory compliance.
- Test laboratories: To perform standardized rating tests and prepare reports that are reproducible and accepted by regulators and certification bodies.
- Regulatory authorities & certification bodies: To verify compliance with Ecodesign and Energy Labelling requirements.
- Specifiers, consultants and HVAC designers: To compare products on a like-for-like basis and select systems for building projects or industrial process cooling.
- R&D teams: For designing and validating new products against standard test conditions.

The standard EN 14511-2:2022 offers a comprehensive framework for the test conditions applicable to air conditioners, liquid chilling packages, and heat pumps that utilize electrically driven compressors. Its primary focus is on establishing a rigorous basis for performance evaluation in both space heating and cooling applications as well as in process chilling. One of the key strengths of this standard is its inclusion of multiple heat transfer media-air, water, and brine-ensuring versatility and broad applicability across various systems. By providing detailed specifications for different configurations, such as single duct and double duct units, the standard enhances the reliability of performance data declarations, which is critical for compliance with Ecodesign Regulation 206/2012 and Energy Labelling Regulation 626/2011. Furthermore, the document’s clear delineation of test conditions for both air-cooled and water/brine-cooled process chillers supports industry stakeholders in maintaining consistent evaluation metrics, thereby fostering a competitive marketplace that emphasizes energy efficiency and environmental sustainability. In summary, EN 14511-2:2022 stands as a pivotal resource for manufacturers and regulators, ensuring that performance claims are substantiated under standard conditions, which in turn promotes consumer confidence in the efficiency of air conditioners and heat pumps.

Die Norm EN 14511-2:2022 bietet eine fundierte Grundlage für die Testbedingungen von Klimaanlagen, Flüssigkeitskühleinheiten und Wärmepumpen, die elektrisch betriebene Kompressoren verwenden. Sie ist besonders relevant für die Bewertung der Leistung dieser Geräte bei der Raumheizung und -kühlung sowie für Prozesskühler. Ein herausragendes Merkmal dieser Norm ist ihre umfassende Abdeckung der Testbedingungen, die sowohl für luft- als auch wasser- oder brinetransfermedien gelten. Dies ermöglicht eine standardisierte Bewertung der Effizienz und Leistung der genannten Systeme und sorgt dafür, dass Verbraucher konsistente und vergleichbare Informationen erhalten. Darüber hinaus legt die Norm spezifische Anforderungen für die Deklaration von Leistungsdaten für Einzel- und Doppelkanaleinheiten fest, was in Übereinstimmung mit der Ökodesignverordnung 206/2012 und der Energie-Label-Verordnung 626/2011 steht. Dies zeigt die enge Verbindung zwischen der Norm und den aktuellen Regulierungen im Bereich der Energieeffizienz, die sowohl Hersteller als auch Verbraucher in ihrem Streben nach umweltfreundlicheren Lösungen unterstützen. Die Relevanz dieser Norm erstreckt sich über die bloße Einhaltung gesetzlicher Vorgaben hinaus. Sie dient als Leitfaden zur Optimierung der Produkteffizienz und zur Förderung nachhaltiger Technologien im Bereich der Klimatechnik. Die Norm unterstützt somit nicht nur die Innovation in der Branche, sondern auch das Engagement der Unternehmen für höhere Umweltstandards. Insgesamt bietet die EN 14511-2:2022 eine entscheidende Struktur zur Gewährleistung der Leistungsfähigkeit und Energieeffizienz von Klimaanlagen und verwandten Technologien und trägt damit zur Schaffung von Vertrauen bei Verbrauchern und Stakeholdern des Marktes bei.
La norme SIST EN 14511-2:2022 constitue un cadre essentiel pour l'évaluation des performances des climatiseurs, des unités de refroidissement à liquide et des pompes à chaleur à compresseurs électriquement entraînés, utilisés pour le chauffage et le refroidissement des espaces, ainsi que pour le refroidissement des processus. Son champ d'application est clairement défini et s'étend à différents types de fluides caloporteurs, y compris l'air, l'eau et le glycol. L'un des points forts de cette norme réside dans sa précision en matière de conditions d'essai. En spécifiant les conditions nécessaires pour la classification des équipements, il garantit que les données de performance déclarées sont fiables et comparables. Les utilisateurs peuvent ainsi avoir une confiance accrue dans les résultats obtenus. Un autre avantage majeur est l'alignement de la norme avec les régulations sur l'éco-conception (Règlement 206/2012) et l'étiquetage énergétique (Règlement 626/2011), ce qui renforce sa pertinence sur le marché. Cela permet non seulement de promouvoir l'efficacité énergétique, mais également d'encourager l'adoption de solutions plus durables pour le chauffage et le refroidissement.
