Diese Europäische Norm legt die Nennbedingungen, Toleranzen und die Darstellung der Leistungsdaten des Herstellers für Verflüssigungssätze für die Kälteanwendung mit Verdichtern des Verdrängertyps fest. Dazu gehören einstufige Verdichter sowie ein und zweistufige Verdichter mit eingebauten Einrichtungen zur Unterkühlung von Flüssigkeiten. Dies ist notwendig, damit ein Vergleich von unterschiedlichen Verflüssigungssätzen durchgeführt werden kann. Die Daten beziehen sich auf die Kälteleistung und die Leistungsaufnahme und umfassen Anforderungen an die Teillastleistung, sofern zutreffend.

General Information

Overview
EN 13215:2016+A1:2020 (CEN) specifies the rating conditions, tolerances and the presentation of manufacturer’s performance data for condensing units for refrigeration that use positive-displacement compressors. It covers single-stage compressors and single- or two-stage compressors with integrated fluid subcooling. The standard ensures consistent, comparable data for refrigerating capacity and power absorbed, and includes requirements for part‑load performance and calculation of seasonal energy performance ratio (SEPR).
Key topics and requirements
- Scope and purpose: Standardizes how manufacturers present performance data so different condensing units can be compared reliably.
- Rated parameters: Defines parameters for presentation (refrigerant, suction temperature or superheat, condensing unit inlet conditions) and requires declaration of the data source for thermodynamic properties.
- Performance data presentation: Data may be published in tabular or graphical form and must cover standard reference points and the allowable working range only.
- Part‑load performance: Requires part‑load data for units with capacity control:
- All control steps for units with 2–4 steps (e.g., multiple compressors, multi-speed motors).
- Maximum, minimum and at least one intermediate point for units with >4 steps or variable capacity (e.g., variable-speed drives).
- Testing basis: Published performance shall be based on tests performed in accordance with EN 13771‑2:2017.
- Correction factors: Provides correction factors and methods to recalculate performance for different superheat and compressor speeds.
- Tolerances and accuracy: Specifies tolerances for published vs actual performance to ensure fair comparison.
- SEPR and evaporating temperature: Includes Annex A (calculation of SEPR) and Annex B (determination of evaporating temperature for refrigerant mixtures), and requires declaration of which evaporating temperature definition is used (dew point, mean temperature, etc.).
- Compatibility and compliance: Annex ZA links the standard to eco‑design requirements (Commission Regulation (EU) No 2015/1095).
Applications
- Creating manufacturer datasheets and catalogs for condensing units with consistent, machine- and buyer‑friendly performance metrics.
- Enabling comparative selection of condensing units for commercial refrigeration, cold rooms, process cooling and industrial applications.
- Supporting compliance with EU ecodesign rules by providing SEPR and part‑load performance data.
- Guiding test laboratories and R&D teams on the presentation and correction of measured performance.
Who uses this standard
- Manufacturers of condensing units and compressors
- Test laboratories and certification bodies
- System designers and specifiers for refrigeration installations
- Procurement and energy managers comparing equipment efficiency
- Regulatory bodies and compliance engineers (ecodesign)

EN 13215:2016+A1:2020は、冷却用の凝縮ユニットの性能データに関して、評価条件、許容差、及びメーカーのパフォーマンスデータの提示方法を定めたヨーロッパ標準です。この標準は、正圧縮型コンプレッサーを用いた冷却システムに特に焦点を当てており、単段および二段のコンプレッサーが含まれ、流体のサブ冷却手段が統合されていることが条件とされています。 この標準の最大の強みは、異なる凝縮ユニットを比較可能にする情報を提供する点です。具体的には、冷却能力や吸収電力に関するデータが含まれており、必要に応じて部分負荷性能に関する要求事項も示されています。これにより、業界内での性能評価が容易になり、消費者が選択を行う際の基準としても機能します。 また、EN 13215:2016+A1:2020は、製造業者が提供する性能データの一貫性と信頼性を保証するためのフレームワークを提供しています。この標準によって、製品の品質管理が強化され、市場での競争力を高めることが可能になります。さらに、冷却システムの効率性を改善するためのガイドラインとしても役立ち、持続可能な技術の推進に寄与しています。 このように、EN 13215:2016+A1:2020は、冷却業界における重要な基準として、製品の性能評価における透明性を向上させ、今後の技術革新においても基盤となる標準です。
The standard EN 13215:2016+A1:2020 serves as a comprehensive framework for the rating conditions, tolerances, and presentation of manufacturer's performance data specifically for condensing units for refrigeration. This European Standard focuses on condensing units equipped with positive-displacement type compressors, which encompass both single stage and multi-stage systems that incorporate an integrated means of fluid subcooling. One of the key strengths of this standard is its structured approach to defining the necessary rating conditions that facilitate uniformity in performance assessments across different condensing units. By establishing standardized methodologies for measuring refrigerating capacity and the power absorbed, EN 13215 ensures that manufacturers can present their performance data in a consistent manner, thereby enabling meaningful comparisons for end-users and industry stakeholders. The inclusion of part-load performance requirements underscores the standard's relevance to real-world applications, as it acknowledges the operational variations encountered in refrigeration systems. This aspect allows for a more comprehensive evaluation of the units' efficiency and effectiveness under different operational circumstances, which is critical for optimizing performance and energy consumption. Furthermore, the standard's focus on tolerances aids in minimizing discrepancies in reported performance data, thus fostering greater transparency and trust among manufacturers, distributors, and consumers. By adhering to the criteria outlined in EN 13215, manufacturers can ensure that their performance claims are substantiated and reliable, which is vital in today's competitive marketplace. In summary, EN 13215:2016+A1:2020 is a vital standard that enhances the uniformity, reliability, and clarity of performance data for condensing units in refrigeration, paving the way for improved decision-making and efficiency within the sector.
EN 13215:2016+A1:2020 표준은 냉동용 응축 장치의 성능 데이터를 평가하기 위한 필수적인 기준을 제공합니다. 이 문서는 양압식 압축기를 사용하는 응축 장치의 평가 조건, 공차 및 제조업체 성능 데이터의 제시에 대한 내용을 다루고 있습니다. 특히, 단일 단계 압축기 및 유체 서브 냉각 기능이 통합된 단일 및 이단계 압축기에 적용됩니다. 이러한 설계는 다양한 응축 장치를 비교할 수 있도록 하여, 사용자에게 적절한 선택을 할 수 있는 기회를 제공합니다. 이 표준의 강점 중 하나는 냉각 능력 및 흡수 전력에 대한 데이터 요구사항을 명확히 하고 있는 점입니다. 또한, 해당 표준은 부분 부하 성능 요건을 포함하여 다양한 운영 조건에서도 안정적인 성능 평가를 가능하게 합니다. 이러한 세부 사항은 제조업체들이 보다 투명하게 성능 데이터를 제시할 수 있도록 하여, 소비자가 선택 시에 실질적인 정보를 제공받을 수 있도록 돕습니다. EN 13215:2016+A1:2020은 또한 유럽 내 냉동 장치 표준화의 중요성을 강조하며, 냉동 기술의 발전과 경쟁력을 결정짓는 요인으로 작용합니다. 이에 따라, 이 표준은 해당 분야의 기업들에게 매우 중요한 문서로 자리 잡고 있으며, 냉동용 응축 장치의 성능 비교를 위한 객관적이고 신뢰할 수 있는 기준을 제공합니다. 이러한 점에서, EN 13215:2016+A1:2020 표준은 현재 냉동 기술 산업에서 필수 불가결한 요소라고 할 수 있습니다.
