Gas-fired sorption appliances for heating and/or cooling with a net heat input not exceeding 70 kW - Part 2: Safety

Edition date: 2026-10-21
In Force
Available languages: French, English
Summary: 1.1 Scope of EN 12309 series Appliances covered by this EN 12309 series include one or a combination of the following: - gas fired sorption chiller; - gas fired sorption chiller/heater; - gas fired sorption heat pump. This EN 12309 series applies to appliances only when used for space heating and cooling with or without heat recovery. This EN 12309 series applies to appliances having flue gas systems of type B and C (according to EN 1749:2020) and to appliances designed for outdoor installations, including type A. EN 12309 does not apply to air conditioners, it only applies to appliances having: - integral burners under the control of fully automatic burner control systems; - closed system refrigerant circuits in which the refrigerant does not come into direct contact with the water or air to be cooled or heated; — mechanical means to assist transportation of the combustion air and/or the flue gas. The above appliances can have one or more primary or secondary functions (i.e. heat recovery - see definitions in EN 12309-1:2023). In the case of packaged units (consisting of several parts), the standard applies only to those designed and supplied as a complete package. The appliances having their condenser cooled by air and by the evaporation of external additional water are not covered by this document. Installations used for heating and/or cooling of industrial processes are not within the scope of these standards. NOTE All the symbols given in this text are used regardless of the language used. 1.2 Scope of this document This document deals with the safety of gas-driven sorption appliances for heating and/or cooling having net heat input not exceeding 70 kW as defined in EN 12309-1:2023. It only applies to appliances: 1) where the temperature of the water does not exceed 105 °C during normal operation; 2) where the maximum operating pressure in the water circuit does not exceed 6 bar; 3) types B12, B13, B22, B23, C12, C13, C32, C33 and C63; 4) for outdoor installations, including type A appliances. This document does not include specific requirements on surface temperatures of external parts particular to children and elderly people.

1.1 Domaine d’application de la série EN 12309 Les appareils concernés par cette série EN 12309 englobent les appareils comportant une ou plusieurs des unités suivantes: — groupe refroidisseur à sorption fonctionnant au gaz; — groupe refroidisseur/réchauffeur à sorption fonctionnant au gaz; — pompe à chaleur à sorption fonctionnant au gaz. La série EN 12309 s’applique aux appareils conçus pour être utilisés uniquement pour le chauffage et le refroidissement de locaux avec ou sans récupération de chaleur. La série EN 12309 s’applique aux appareils comportant des systèmes d’évacuation des gaz de combustion de types B et C (conformément à l’EN 1749:2020) et aux appareils conçus pour les installations extérieures, notamment ceux du type A. L’EN 12309 ne s’applique pas aux climatiseurs, elle s’applique uniquement aux appareils comportant: — des brûleurs intégrés sous le contrôle de systèmes de commande automatique; — des circuits fermés de fluide frigorigène dans lesquels le fluide frigorigène n’est pas au contact de l’eau ou de l’air à refroidir ou à chauffer; — des moyens mécaniques pour l’alimentation en air de combustion et/ou l’évacuation des produits de combustion. Les appareils susmentionnés peuvent présenter une ou plusieurs fonctions primaires ou secondaires (c’est à dire récupération de chaleur, voir les définitions dans l’EN 12309 1:2023). Dans le cas des appareils fournis prêts à l’emploi (constitués de plusieurs éléments), la norme ne s’applique qu’à ceux conçus et fournis sous forme d’ensemble complet. Le présent document ne couvre pas les appareils ayant leur condenseur refroidi par air et par évaporation d’eau d’un circuit supplémentaire externe. Ces normes ne s’appliquent pas aux installations utilisées pour le chauffage et/ou le refroidissement des procédés industriels. NOTE Tous les symboles spécifiés dans le présent document sont utilisés, quelle que soit la langue utilisée. 1.2 Domaine d’application de ce document Ce document traite de la sécurité des appareils à sorption fonctionnant au gaz pour le chauffage et/ou le refroidissement de débit calorifique sur PCI inférieur ou égal à 70 kW, tel que défini dans l’EN 12309 1:2023. Elle ne s’applique qu’aux appareils: 1) dont la température de l’eau ne dépasse pas 105 °C en fonctionnement normal; 2) dont la pression maximale de service dans le circuit d’eau ne dépasse pas 6 bar; 3) des types B12, B13, B22, B23, C12, C13, C32, C33 et C63; 4) conçus pour les installations extérieures, y compris les appareils du type A. Le présent document ne contient pas d’exigences spécifiques concernant les températures de surface des parties externes, en particulier pour les enfants et les personnes âgées.

1.1 Anwendungsbereich der Normenreihe EN 12309 Geräte, die von dieser Normenreihe EN 12309 abgedeckt werden, beinhalten eine oder eine Kombination der folgenden Funktionen:  gasbefeuertes Sorptionskühlgerät;  gasbefeuertes Sorptionskühl-/-heizgerät;  gasbefeuerte Sorptionswärmepumpe. Diese Normenreihe EN 12309 gilt ausschließlich für Geräte für die Raumheizung und -kühlung mit oder ohne Wärmerückgewinnung. Diese Normenreihe EN 12309 gilt für Geräte mit Abgassystemen der Bauart B und Bauart C (nach EN 1749:2020) sowie für Geräte zur Installation im Freien, einschließlich Bauart A. EN 12309 ist nicht für Klimageräte anwendbar, sondern gilt ausschließlich für Geräte mit:  integrierten Brennern, gesteuert mittels Feuerungsautomaten;  geschlossenen Kühlkreisläufen, in denen das Kühlmittel nicht direkt mit dem/der zu kühlenden oder zu erwärmenden Wasser oder Luft in Berührung kommt;  mechanischen Einrichtungen zur Unterstützung der Verbrennungsluftzufuhr und/oder Abgasabführung. Die vorstehenden Geräte können eine oder mehrere Primär- oder Sekundärfunktion(en) aufweisen (d. h. Wärmerückgewinnung — siehe Begriffe nach EN 12309 1:2023). Bei (aus mehreren Teilen bestehenden) Verpackungseinheiten gilt die vorliegende Norm nur, wenn diese Einheiten als vollständige Baugruppe ausgelegt und geliefert werden. Dieses Dokument behandelt nicht Geräte, deren Kondensator mit Luft und durch Verdampfung von zusätzlichem Wasser auf der Außenseite gekühlt wird. Anlagen für Heizung und/oder Kühlung industrieller Prozesse fallen nicht in den Anwendungsbereich dieser Normen. ANMERKUNG Sämtliche in diesem Text angegebenen Symbole werden unabhängig von der jeweiligen verwendeten Sprache angewendet. 1.2 Anwendungsbereich dieses Teils 2 von EN 12309 Dieser Teil von EN 12309 behandelt die Sicherheit von gasbefeuerten Sorptions-Geräten für Heizung und/oder Kühlung mit einer Nennwärmebelastung nicht über 70 kW, wie in EN 12309 1:2023 festgelegt. Er gilt ausschließlich für Geräte: 1) bei denen die Wassertemperatur während des Normalbetriebs 105 °C nicht überschreitet; 2) bei denen der Höchstbetriebsdruck im Wasserkreislauf 6 bar nicht überschreitet; 3) der Bauarten B12, B13, B22, B23, C12, C13, C32, C33 und C63; 4) für Installationen im Freien, einschließlich Geräten der Bauart A.
