La norme EN ISO 9806:2017, intitulée "Énergie solaire - Capteurs solaires thermiques - Méthodes d'essai", constitue un document fondamental pour les professionnels du secteur des énergies renouvelables. Son champ d'application est clairement défini et englobe des méthodes d'essai essentielles pour évaluer la durabilité, la fiabilité, la sécurité et la performance thermique des capteurs solaires à fluide. Cette norme est applicable à une vaste gamme de capteurs, notamment les capteurs solaires pour le chauffage de fluides, les capteurs de chauffage d'air, ainsi que les systèmes hybrides qui fournissent à la fois de la chaleur et de l'électricité. L'un des points forts de la norme ISO 9806:2017 est sa capacité à être utilisée tant pour des tests en laboratoire que pour des tests in situ, garantissant ainsi que les collecteurs solaires sont adaptés à une variété d'applications réelles. Cette flexibilité est cruciale pour les fabricants et les installateurs qui souhaitent assurer la qualité et la performance de leurs produits dans des conditions de fonctionnement variées. Un autre atout majeur de cette norme réside dans sa pertinence pour les technologies solaires modernes, tel que l'inclusion de capteurs utilisant des sources d'énergie externes pour un fonctionnement normal et/ou des objectifs de sécurité. Cela reflète l'évolution du secteur vers des solutions plus intégrées et plus sûres, et permet une évaluation complète des dispositifs utilisés dans le cadre de la transition énergétique. Cependant, il est à noter que la norme ne couvre pas les aspects de sécurité électrique ou d'autres propriétés spécifiques liées à la production d'électricité. De plus, elle n'est pas applicable aux dispositifs pour lesquels une unité de stockage thermique est intégralement liée au processus de collecte, ce qui pourrait limiter son utilisation dans certains systèmes de stockage d'énergie thermique. Dans l'ensemble, la norme EN ISO 9806:2017 est essentielle pour s'assurer que les collecteurs solaires thermiques répondent à des critères rigoristes de performance et de sécurité, contribuant ainsi à la fiabilité et à l'acceptation croissante des technologies solaires sur le marché. Son adoption par les acteurs de l'industrie est un gage de qualité qui renforce la confiance des consommateurs et favorise le développement durable dans le secteur de l'énergie solaire.
Die EN ISO 9806:2017 ist ein bedeutendes Dokument, das die Prüfmethoden zur Bewertung der Haltbarkeit, Zuverlässigkeit, Sicherheit und thermischen Leistung von thermischen Solarkollektoren detailliert festlegt. Der Umfang dieses Standards ist weitreichend und umfasst verschiedene Typen von fluideheizenden Solarkollektoren, darunter Luftheizkessel und hybride Kollektoren, die sowohl Wärme als auch elektrische Energie erzeugen. Dies macht die Norm besonders relevant für die wachsende Branche der Solarenergie, die zunehmend auf innovative Lösungen setzt. Ein herausragendes Merkmal der EN ISO 9806:2017 ist die Möglichkeit, die beschriebenen Testmethoden sowohl im Labor als auch vor Ort anzuwenden. Dadurch wird sichergestellt, dass die Ergebnisse unter unterschiedlichen Bedingungen und nicht nur in kontrollierten Umgebungen geprüft werden können, was die Aussagekraft und Anwendbarkeit der Prüfungen erhöht. Die Norm ist von besonderer Bedeutung für Hersteller und Betreiber von Solarkollektoren, da sie durch die standardisierten Prüfmethoden eine objektive Grundlage zur Beurteilung der Leistung und Sicherheit bietet. Die Einhaltung der Norm ermöglicht es den Unternehmen, ihre Produkte effizienter zu vermarkten und das Vertrauen der Verbraucher in die Qualität und Sicherheit der Kollektoren zu stärken. Ein weiterer Vorteil der EN ISO 9806:2017 ist, dass sie den großen Bereich der solarthermischen Technologien adressiert, während sie gleichzeitig spezifische Vorgaben für die Nutzung externer Energiequellen für den normalen Betrieb und Sicherheitszwecke beschreibt. Dies fördert die Integration solcher Kollektoren in moderne Systeme und unterstützt die Entwicklung nachhaltiger Energielösungen. Es ist jedoch zu beachten, dass die Norm nicht auf Geräte anwendbar ist, bei denen eine thermische Speichereinheit integraler Bestandteil ist und der Sammelprozess nicht vom Speicherprozess getrennt werden kann. Dies limitiert den Anwendungsbereich der Norm und sollte von Nutzern und Herstellern in Betracht gezogen werden. Insgesamt bietet die EN ISO 9806:2017 eine unverzichtbare Grundlage für die Entwicklung, den Test und die Vermarktung von solaren Heizsystemen und stärkt die Relevanz der Solarenergie in der heutigen energiepolitischen Landschaft.
SIST EN ISO 9806:2018は、太陽エネルギーに関する重要な基準であり、主に液体加熱用太陽集熱器の耐久性、信頼性、安全性および熱性能を評価するための試験方法を定めています。この基準は、実験室での試験や現地での試験の両方に適用できるため、実践的な使用において非常に有用です。 この標準の強みは、流体加熱用及び空気加熱用の太陽集熱器、熱と電力を同時に生成するハイブリッド太陽集熱器、さらには正常運転や安全目的のために外部エネルギーを使用する太陽集熱器に対応している点です。この広範な適用範囲により、様々な技術的ニーズに応じた試験が可能になります。 また、ISO 9806:2017は、電力生成に直接関連する特定の特性や電気安全性の側面を網羅していないことを明確にしており、これにより、試験対象の明確な線引きが行われています。さらに、熱貯蔵装置が集熱器の構成要素として不可分である場合、この基準は適用されないことが規定されており、集熱性能測定の正確性を確保しています。 このように、SIST EN ISO 9806:2018は、太陽熱集熱器の性能評価に関する信頼性の高い基準であり、エネルギー効率や持続可能な開発における重要な役割を果たすことが期待されます。太陽エネルギーの利用推進に対する関連性は高く、今後の技術革新に貢献するスタンダードとして位置付けられています。
The EN ISO 9806:2017 standard is a comprehensive document that outlines test methods for evaluating the durability, reliability, safety, and thermal performance of fluid heating solar collectors. This standard's scope covers a diverse range of solar collector types, including fluid heating solar collectors, air heating solar collectors, and hybrid solar collectors that co-generate heat and electrical power. This inclusivity ensures that it meets the needs of various stakeholders involved in solar thermal technologies. One of the significant strengths of ISO 9806:2017 is its applicability to both laboratory testing and in situ testing environments. This dual approach allows for the assessment of solar collectors under controlled conditions as well as real-world scenarios, thereby providing a robust validation of performance metrics. The standard ensures that manufacturers and users can trust the results from these tests, leading to better decision-making in the deployment and use of solar thermal systems. Moreover, the standard defines clear methodologies for the assessment of critical aspects such as safety and thermal performance, which are vital for the operational integrity of solar collectors. However, it is pertinent to note that the standard does not cover electrical safety aspects, nor does it address specific properties associated with electric power generation. This focus on thermal performance is precisely aligned with the standard's aim and makes it particularly relevant for entities involved in thermal solar energy applications. While ISO 9806:2017 does not include collectors that integrate thermal storage units to a degree where collection and storage processes cannot be measured separately, this clarification helps maintain a focused scope. It ensures that the test methods provided are tailored for those systems where distinct thermal performance metrics can be achieved, thereby enhancing the reliability of rating and comparison across different models. Overall, EN ISO 9806:2017 represents a significant reference in the solar energy sector, advancing the understanding and measurement of solar thermal collectors. Its comprehensive test methods provide essential guidelines that support manufacturers and stakeholders in ensuring high-quality, reliable, and efficient solar collector systems.
SIST EN ISO 9806:2018 표준은 태양 에너지와 관련하여 열 수집기의 내구성, 신뢰성, 안전성 및 열 성능을 평가하기 위한 테스트 방법을 규정하고 있습니다. 이 표준은 실험실 테스트 및 현장 테스트 모두에 적용 가능하다는 점에서 매우 유용하며, 다양한 유형의 유체 가열 태양열 수집기에 대한 포괄적인 적용 범위를 제공합니다. 이 표준의 강점 중 하나는 공기 가열 태양열 수집기 및 열과 전력을 동시에 생성하는 하이브리드 태양열 수집기와 같은 다양한 수집기 유형에 적용될 수 있다는 점입니다. 또한, 외부 전원 소스를 사용하는 태양열 수집기에 대해서도 안전한 운영과 기타 일반적인 목적을 위한 지침을 제공하므로, 실제 설비에서의 다양성에 대한 적절한 대응력을 보여줍니다. ISO 9806:2017은 태양열 수집기의 성능 측정을 위한 테스트 방법을 정의하고 있지만, 전기 안전성이나 전력 생산과 직접 관련된 특정 속성은 다루지 않습니다. 이로 인해 사용자들은 전력 관련 안전성을 별도로 고려해야 하며, 이러한 구분은 이 표준이 다루는 범위를 명확히 하여 더욱 전문적인 적용을 가능하게 합니다. 결론적으로, SIST EN ISO 9806:2018 표준은 태양열 수집기의 성능 평가에 있어 중요한 기준을 제공하며, 그 적용 범위와 실용성을 통해 태양 에너지 분야의 기술 발전에 기여하는 바가 큽니다. 이 표준은 특히 태양열 시스템을 설계하고 검증하는 데 있어 필수적이며, 사용자 및 제조업체에게 명확하고 신뢰할 수 있는 기초 자료를 제공합니다.
