Dies ist besonders relevant für Planer und Hersteller, die effiziente und standardisierte Lösungen für Temperaturregulierung benötigen. Ein zentraler Schwerpunkt der Norm liegt auf der thermischen Leistung, die unter standardisierten Bedingungen für Heiz- und Kaltwasseranwendungen ermittelt wird. Die Einführung detaillierter Prüfverfahren ermöglicht es, die Effizienz und Leistung von Fancoil-Einheiten präzise zu bewerten. Dies ist besonders wertvoll in der heutigen Zeit, in der Energieeffizienz und nachhaltige Gebäudetechnik im Vordergrund stehen. Zudem berücksichtigt die Norm sowohl luftfreigebende als auch luftgeführte Einheiten mit einem maximalen externen statischen Druck von 120 Pa, was ihre Anwendbarkeit in verschiedenen Installationsszenarien erhöht. Ein weiterer Vorteil dieser Norm ist die umfassende Behandlung der unterschiedlichen Lüftergeschwindigkeitssteuerungen, sei es variabel oder mehrstufig. Die Norm gewährleistet, dass alle Arten von Fancoil-Einheiten gleich behandelt werden und ermöglicht somit einen fairen Vergleich der Leistung unter identischen Prüfbedingungen. Wesentlich ist zudem, dass die EN 1397:2015 keine Lüftungsfunktionen behandelt, was für Benutzer von Bedeutung ist, die sich ausschließlich auf die Heiz- und Kühlleistung konzentrieren wollen. Die Vorgabe, frische Luftanbindungen während der Tests geschlossen zu halten, gewährleistet, dass die Prüfergebnisse ausschließlich die Komfortfunktionen der FCU widerspiegeln. Die Norm liefert auch einen klaren Rahmen zur Bestimmung der Luftstromrate, die von der Fancoil-Einheit bereitgestellt wird. Dies trägt zur Verbesserung der Systemintegration und zur Vereinfachung der Planung bei, da die bei verschiedenen Bedingungen erzielten Leistungen ebenfalls berücksichtigt werden können. Es ist wichtig zu beachten, dass die Norm nicht die Bewertung von Heiz- oder Kühlleistungen von direkt expandierenden Spulen oder von elektrischen Widerstandselementen abdeckt, und auch die akustische Leistung, die in der EN 16583 behandelt wird, nicht Teil dieser Norm ist. Daher ist die EN 1397:2015 speziell auf die thermische und lufttechnische Performance von Fancoil-Einheiten ausgerichtet. Zusammenfassend lässt sich sagen, dass die EN 1397:2015 eine wertvolle Ressource für Fachleute im Bereich der Heizungs-, Lüftungs- und Klimatechnik darstellt, die eine klare und zuverlässige Grundlage für die Bewertung und den Vergleich von hydronischen Fancoil-Einheiten bietet.
SIST EN 1397:2015은 수소 열교환기의 기초를 제공하며, 히드로닉 룸 팬 코일 유닛(FCU)의 성능을 확인하기 위한 테스트 절차에 대한 유럽 표준이다. 본 표준은 기능 면에서 냉각 또는 난방 기능을 제공하는 공장 제작된 단일 조립체인 팬 코일 유닛에 적용된다. 이는 냉각 또는 난방의 출처를 포함하지 않으며, 공기 자유 배달 및 덕트식 유닛을 포함한다. 이 표준의 강점 중 하나는 다양한 팬 속도 조절 방식을 아우르며, 변속 및 다속 방식의 팬 코일 유닛 모두에 적용될 수 있다는 점이다. 또한, 유닛의 냉각 및 난방 기능의 성능을 표준 조건에서 측정할 수 있는 방법을 제공한다. 이는 따뜻한 물 또는 차가운 물, 또는 이의 혼합물을 사용할 수 있는 상황에서 중요하다. 또한, 팬 코일 유닛이 제공하는 공기 흐름 속도 측정 방법을 포함하고 있어 사용자에게 실질적인 데이터 제공이 가능하다. 그러나 센서 직접 확장 코일에서의 난방 또는 냉방 성능의 평가, 및 전기 저항 요소에 의한 난방의 속성은 포함하지 않으므로 이러한 점도 고려할 필요가 있다. 표준은 또한 팬 코일 유닛의 소음 성능을 다루지 않으며, 이는 EN 16583에서 다루어진다. 이로 인해, 사용자는 단순히 성능 측정에 집중할 수 있다. 결론적으로, SIST EN 1397:2015 표준은 히드로닉 팬 코일 유닛의 성능을 평가하기 위한 포괄적이고 실용적인 기준을 제공하며, 냉각 및 난방 기능에 대한 명확한 시험 절차를 통해 업계 기준을 설정하는 데 기여한다.
SIST EN 1397:2015は、ハイドロニックファンコイルユニット（FCU）に関する重要な国際基準であり、冷却や加熱の性能を評価するためのテスト手順を提供しています。この標準は、工場製の単一アセンブリとして設計されたFCUに適用され、冷却源や加熱源は含まれません。これにより、設計者や技術者は特定のアプリケーションに最適なファンコイルユニットを選択する際に一貫した基準を持つことができます。 この標準の大きな強みは、様々なファン速度制御（可変速度、多段階速度）のFCUに対応している点です。これにより、異なる用途に応じた性能を確認することが可能となり、ユーザーの要求に柔軟に応えることができます。さらに、最大外部静圧が120Paまでの空気自由供給およびダクト接続型ユニットをカバーすることで、多様なインストール条件に適用可能な汎用性を提供しています。 重要な点として、SIST EN 1397:2015は、FCUの冷却および加熱機能に焦点を当てており、室内空間の熱交換機としての役割を明確にしています。この基準は、熱性能を標準条件下で定量化する方法を提供し、実際の運用条件でも使用可能なテスト手順を示しています。このことは、設計や施工の段階で冷暖房システムの性能を確保する上で非常に重要です。 ただし、換気機能や直接膨張コイルからの加熱、および電気抵抗要素からの加熱の評価は含まれておらず、これらの評価は他の基準に委ねられています。ファンコイルユニットの音響性能についてはEN 16583で取り扱われているため、音に関する要求は別の評価基準を参考にする必要があります。また、製造やフィールドテストに使用されるテストの指定は目的としていないため、この標準は製品の持続的な評価の基礎に役立つことを目的としています。 総じて、SIST EN 1397:2015は、ハイドロニックファンコイルユニットの性能を評価するための体系的かつ実践的なアプローチを提供し、冷房および暖房の分野における信頼性の高い指針となることが期待されます。これにより、業界全体での標準化が促進され、製品の品質向上に貢献するでしょう。
The EN 1397:2015 standard offers a comprehensive framework for evaluating the performance of hydronic room fan coil units (FCUs), underscoring its significance within the HVAC industry. Its scope is clearly defined, addressing factory-made assemblies designed for heating and cooling without incorporating the temperature source, making it highly relevant for manufacturers and technicians in the field. One of the standard's key strengths is its inclusive coverage of both air free delivery and air ducted units, with specifications set for a maximum external static pressure of 120 Pa. This ensures a broad application across different types of fan coil units, accommodating various design and functional needs. Furthermore, by addressing multiple fan speed controls-variable and multispeed-the EN 1397:2015 standard allows for flexible implementation in diverse operational settings. The detailed test procedures outlined in the standard enable users to accurately determine thermal performance during standardized conditions using hot or chilled water or water mixtures. This precision in testing is essential for ensuring that FCUs deliver the expected performance metrics in real-world applications. Moreover, the inclusion of guidelines for measuring air flow rates provided by the fan coil units adds another layer of practicality for users seeking to optimize HVAC systems. Importantly, the standard delineates its limitations by excluding ventilation functionalities, as well as the assessment of acoustic performance, which is covered under EN 16583. This clarity helps users grasp the specific applicability of EN 1397:2015 without confusion regarding its intended use. Overall, the EN 1397:2015 standard serves as a crucial reference point for professionals involved in the performance testing of hydronic fan coil units. Its structured approach to defining testing methods enhances the reliability of performance assessments within the HVAC sector, making it an indispensable part of product development and quality assurance processes.
La norme EN 1397:2015 se concentre sur les unités de traitement d'air fonctionnant par circulation d'eau, plus communément connues sous le nom de fan coil units (FCU). Cette norme européenne définit des procédures de test pour établir les performances de ces systèmes, qu'ils soient destinés au refroidissement ou au chauffage. Le domaine d'application de la norme est clair et précis : elle s'applique exclusivement aux unités de fan coil fabriquées en usine qui n'incluent pas la source de refroidissement ou de chauffage, ce qui permet de se concentrer sur les performances intrinsèques des unités elles-mêmes. L'un des points forts de la norme est son approche systématique pour obtenir des données de performance thermique sous des conditions standard. Cela inclut des tests pour les unités à débit d'air libre et à conduit d'air, avec une pression statique externe maximale de 120 Pa, ce qui assure une évaluation cohérente et rigoureuse de l'efficacité énergétique de ces appareils. De plus, la norme prend en compte tous les types de contrôle de vitesse de ventilateur, qu'ils soient variables ou multivitesse, ce qui renforce son applicabilité à différents types de systèmes de climatisation. La norme EN 1397:2015 est d'une grande pertinence dans le contexte actuel où l'efficacité énergétique et le confort intérieur sont des priorités croissantes dans la conception de systèmes de CVC. En se concentrant uniquement sur les fonctions de refroidissement et de chauffage, sans traiter des aspects de ventilation, elle permet aux fabricants de se focaliser sur l'optimisation des performances thermiques de leurs unités. Cela garantit que les utilisateurs finaux bénéficient de produits conformes, efficaces et adaptés à des environnements spécifiques. Il est également important de noter que les méthodes de test fournies par cette norme peuvent être adaptées pour des conditions supplémentaires, permettant une flexibilité dans l’analyse de performance. Cependant, la norme ne couvre pas certains aspects tels que la performance acoustique, qui est abordée par la norme EN 16583, ce qui limite son champ d’application à des tests de performance strictement thermiques. En somme, la norme EN 1397:2015 représente un outil essentiel pour les fabricants et les professionnels du secteur, car elle offre une méthodologie claire pour évaluer les unités de fan coil dans un cadre standardisé. Sa structure rigoureuse et son contenu ciblé font d'elle une référence incontournable pour garantir des performances optimales des systèmes de climatisation d'aujourd'hui.
