EN 12309-6:2014 표준은 난방 및/또는 냉각을 위한 가스 연료 기반 흡수 장치의 계절 성능 계산 방법을 명시합니다. 이 표준은 정격 열 입력이 70 kW를 초과하지 않는 장치에 해당하며, 가스 연료 기반 흡수 칠러, 가스 연료 기반 흡수 칠러/히터 및 가스 연료 기반 흡수 히트 펌프를 포함합니다. 따라서 이 표준의 적용 범위는 다양한 가스 연료 기반 장치의 설계 및 설치에 중요한 기초를 제공합니다. EN 12309-6의 강점은 시스템 에너지 효율성 계산을 위한 공통된 기준을 제공함으로써, 여러 장치의 에너지 성능을 비교하고 최적화할 수 있도록 한다는 점입니다. 특히, 단일 및 이중 기능 장치의 냉각 및 난방 모드에서의 성능을 계산하는 방법이 명시되어, 사용자가 보다 신뢰할 수 있는 성능 데이터를 기반으로 의사결정을 할 수 있게 돕습니다. 이러한 기준은 특히 건물 내 특정 히트 펌프 시스템의 에너지 효율성을 계산하는 과정에서 매우 유용합니다. 또한, 표준은 B형과 C형 배기 가스 시스템을 갖춘 장치와 야외 설치를 위한 장치에 엄격히 적용되며, 완전 패키지로 설계되고 공급된 장치에만 적용됩니다. 이는 설치의 일관성을 유지하고 안전성을 보장하는 데 기여합니다. 또한 EN 12309는 통합 연소기와 완전 자동 연소기 제어 시스템을 사용하는 냉매 회로 같은 특정 시스템에만 적용되므로, 사용자는 더욱 정확한 기술적 요건을 이해할 수 있게 됩니다. 결론적으로, EN 12309-6:2014 표준은 가스 연료 기반 흡수 장치의 계절 성능 평가에 있어 필수적인 기준을 제공하며, 이를 통해 사용자와 제조업체는 기기 성능을 효율적으로 관리하고 최적화할 수 있는 기회를 제공합니다.
The EN 12309-6:2014 standard offers a comprehensive framework for evaluating the seasonal performance of gas-fired sorption appliances designed for heating and/or cooling applications. Covering appliances with a net heat input not exceeding 70 kW, this standard delineates the scope specifically to gas-fired sorption chillers, chiller/heaters, and heat pumps, while clarifying excluded appliances, such as traditional air conditioners. The strength of EN 12309-6 lies in its detailed methodologies for calculating seasonal performance metrics, particularly in terms of reference seasonal performances for both heating and cooling modes. This is particularly relevant for professionals who seek to ensure energy efficiency in HVAC systems, as it provides critical guidance for calculating energy efficiency in heating mode as per the requirements set forth in EN 15316-4-2. The standard's focus on appliances featuring integral burners with fully automated control systems, alongside closed refrigerant circuits, emphasizes a commitment to safety and efficiency. By not applying to systems that rely solely on air-cooled condensers, it upholds stringent criteria for operational parameters. Additionally, the inclusion of guidelines for bivalent and monovalent appliance configurations addresses a vital aspect of modern HVAC applications. EN 12309-6's clear specifications and definitions bolster its applicability and significance in the industry, making it a crucial reference for manufacturers, engineers, and energy assessors involved in the design and evaluation of gas-fired sorption appliances. Overall, the standard effectively balances rigor with practical relevance, solidifying its role as an essential tool in the pursuit of energy-efficient appliance technologies.
Die Norm EN 12309-6:2014 ist von zentraler Bedeutung für die Berechnung der saisonalen Leistungen von gasbetriebenen Sorptionsgeräten zur Heiz- und Kühltechnik mit einer Netto-Wärmeleistung von maximal 70 kW. Ihre Stärken liegen in der klaren Definition des Anwendungsbereichs und der robusten Methodik zur Berechnung der saisonalen Leistungen, die sowohl für monovalente als auch bivalente Geräte anwendbar ist. Die Norm schafft eine einheitliche Basis für die Bewertung der energetischen Effizienz von Heiz- und Kühlgeräten, was für die Optimierung von Systemen in modernen Gebäuden von entscheidender Bedeutung ist. Durch die Fokussierung auf Geräte mit integrierten Brennern, die durch vollautomatische Brennsteuerungen geregelt werden, und geschlossenen Kältemittelkreisläufen bietet die Norm klare Richtlinien für die Entwicklung und den Einsatz neuer Technologien. Besondere Beachtung finden hierin auch Anforderungen an die Abgasführung, die für Typ B und Typ C konzipiert sind, sowie die Regelungen für Außeninstallationen, wodurch die Anwendungen in vielfältigen Umgebungen gefördert werden. Die Norm legt zudem fest, dass sie nicht für Klimaanlagen gilt, sondern sich auf die spezifischen Geräte konzentriert, die einer klaren Definition folgen und die Effizienz von Heizsystemen deutlich steigern können. Die Methodik zur Berechnung von saisonalen Leistungen sorgt dafür, dass die Ergebnisse der Energieeffizienz für gasbetriebene Sorptionsgeräte verlässlich und nachvollziehbar sind. Insgesamt stellt EN 12309-6:2014 eine wertvolle Ressource dar, um die Leistung von Heiz- und Kühlgeräten zu bewerten, und trägt damit zur Förderung des umweltfreundlichen Einsatzes von Energie in Gebäuden bei. Die enge Anbindung an andere Normen, wie zum Beispiel EN 15316-4-2, stärkt die Relevanz dieser Norm und erleichtert Fachleuten die Implementierung und Anwendung in der Praxis.
La norme EN 12309-6:2014 offre une structure précise pour le calcul des performances saisonnières des appareils à sorption à gaz, utilisés pour le chauffage et/ou la climatisation, avec une puissance thermique nette ne dépassant pas 70 kW. Cette norme couvre une large gamme d'appareils, y compris les refroidisseurs à sorption à gaz, les refroidisseurs/chauffages à sorption à gaz et les pompes à chaleur à sorption à gaz, démontrant ainsi sa pertinence dans le domaine des technologies de gestion de l'énergie. Parmi les points forts de la norme, il convient de souligner son approche systématique pour le calcul des performances saisonnières, qui s'applique aux appareils à fonctions monovalentes et bivalentes. Ce cadre méthodologique permet non seulement de standardiser les techniques de calcul, mais aussi de garantir une cohérence dans l'évaluation de l'efficacité énergétique, conformément aux exigences de la norme EN 15316-4-2. Cela souligne l'importance de l'EN 12309-6 dans l'optimisation de la performance énergétique des systèmes dans les bâtiments. De plus, le fait que cette norme s'applique spécifiquement aux appareils avec des systèmes de gaz de combustion de type B et C, ainsi qu'aux installations destinées à l'extérieur, en fait un outil précieux pour les professionnels de l'industrie qui cherchent à respecter les réglementations en matière de sécurité et d'efficacité énergétique. Toutefois, il est essentiel de noter que la norme n'inclut pas les climatiseurs traditionnels, ce qui permet de cibler plus efficacement les appareils à sorption dédiés. En résumé, la norme EN 12309-6:2014 se révèle être une référence pertinente et complète pour le secteur des appareils de chauffage et de climatisation à sorption à gaz. Elle contribue à l'établissement de pratiques standardisées et d'une évaluation précise des performances énergétiques, renforçant ainsi l'importance croissante des solutions énergétiques durables dans le secteur.
EN 12309-6:2014は、70 kW以下の正味熱入力を持つガス焚き吸収機器による暖房および冷却のための季節性能の計算方法を明確に定義する非常に重要な標準です。この規格は、ガス焚き吸収冷却器や、ガス焚き吸収冷却器/暖房器、ガス焚き吸収熱ポンプなどの機器に適用されることが明記されており、特にスペース暖房や冷却、または冷蔵に向けて設計された機器を対象としています。 この標準の強みは、その明確な適用範囲にあります。例えば、EN 12309は、熱回収の有無にかかわらず、特定の要件に従ったフルオーギスシステムを持つ機器に焦点を当てています。また、完全自動バーナー制御システムに基づく内部バーナーや、冷却・加熱される水や空気と直接接触しない密閉式冷媒回路を有する機器が適用対象になります。そのため、ガス焚き吸収機器の特性を正確に理解し、効率を計算するための充分な基盤を提供しています。 さらに、この文書は、季節的な性能の計算方法に特化しており、モノバレント及びバイバレント機器の冷却及び暖房モードにおける季節的性能を評価するための指針を提供します。特に、建物における特定の熱ポンプシステムの暖房モードにおけるエネルギー効率計算のための出発点としての役割を果たします。 全体として、EN 12309-6:2014は、ガス焚き吸収機器の効率的な運用を促進するために不可欠な要素を提供しており、実用性と技術的整合性を兼ね備えています。特に、エネルギー効率の最適化が求められている現代において、この標準はますますその重要性を増しています。
