EN 50465:2015

Gas appliances - Combined heat and power appliance of nominal heat input inferior or equal to 70 kW

This European Standard specifies the requirements and test methods for the construction, safety, fitness for purpose, rational use of energy and the marking of a micro combined heat and power appliance; (hereafter referred to as “mCHP appliance”). This European Standard applies to mCHP appliances of types B22, B23, B32, B33, B52, B53, C1, C3, C42, C43 C52, C53, C62, C63, C82, C83 and C9 based on the classifications of CEN/TR 1749: – that use one or more supplied gases of the three gas families at the pressures stated in EN 437, – where the temperature of the heat transfer fluid of the heating system (heating water circuit) does not exceed 105 ºC during normal operation, – where the maximum operating pressure in the - heating water circuit does not exceed 6 bar, - domestic hot water circuit (if installed) does not exceed 10 bar, – which are either intended to be installed indoors or outdoors in a partially protected place, – which are intended to produce hot water either by the instantaneous or storage principle, – which have a maximum heat input (based on net calorific value) not exceeding 70 kW, – which are designed for sealed or open water systems. NOTE 1 For applications where the maximum allowable water temperature exceeds 110 ºC or where volume multiplied by maximum allowable pressure exceeds 50 bar litres, further requirements may be necessary to comply with the essential requirements of Directive 97/23/EC (Pressure Equipment Directive (PED)). NOTE 2 For mCHP appliances with constructions that might not be fully covered by this European Standard or by another specific standard, the risk associated with the alternative construction will be assessed. NOTE 3 This EN includes formulae and methods intended to produce values required by implementation measures of the ErP Directive 2009/125/EC and Labelling Directive 2010/30/EU. NOTE 4 EN 13203-4 will specify the assessment of energy consumption for domestic hot water production of gas combined heat and power appliances (mCHP). This European Standard does not contain the requirements necessary for appliance capable of producing electrical energy without using the thermal energy. This European Standard does not cover all the requirements for mCHP appliances that are intended to be connected to gas grids where the quality of the distributed gas is likely to vary to a large extent over the lifetime of the appliance (see Annex DD).

Gasgeräte - Geräte zur Kraft-Wärme-Kopplung mit einer Nennwärmebelastung kleiner oder gleich 70 kW

Dieser Entwurf legt die Anforderungen und Prüfmethoden für den Bau, die Sicherheit, die Gebrauchstauglichkeit und den rationellen Energieeinsatz und die Kennzeichnung von Mikro-Kraft-Wärme-Kopplungsanlagen (ab hier als µKWK-Anlage bezeichnet). Dieser Entwurf gilt bei µKWK-Anlagen der Typen B22, B23, B32, B33, B52, B53, C1, C3, C4, C5, C6, und C8, wie in CEN/TR 1749 spezifiziert, – die ein oder mehr Verbrennungsgase der drei Gasfamilien bei den in EN 437 angegebenen Drücken verwenden – bei welchen die Temperatur des Wärmetauschermediums 105 °C bei Nennbetrieb nicht überschreitet. – bei welchen der maximale Betriebsdruck im • Heizwasserkreislauf 6 bar nicht überschreitet, • häuslichen Warmwasserkreislauf (falls installiert) maximal 10 bar beträgt. – die unter bestimmten Umständen Kondensation hervorrufen können; – die vom Hersteller als Brennwertgerät bezeichnet werden; – die vorgesehen sind für den Einbau in teilweise geschützte Räume; – die vorgesehen sind um Warmwasser entweder durch Durchlauf- oder Speicherprinzip zu erzeugen; – die eine maximale Wärmebelastung (bezogen auf Brennwert)von 70 kW nicht überschreiten; – die für abgedichtete oder offene Wassersysteme konstruiert sind; ANMERKUNG 1 Anwendungen, deren maximal erlaubte Temperatur 110 °C überschreitet, oder bei denen das Volumen multipliziert mit dem maximal erlaubten Druck 50 bar•liter übersteigt, können weitere Anforderungen nach sich ziehen, um den notwendigen Anforderungen der Direktive 97/23/EC (Pressure Equipment Directive (PED)) zu genügen. ANMERKUNG 2 Für µKWK-Geräte mit einer Bauart, die nicht vollständig durch diese Norm oder eine andere spezielle Norm abgedeckt sind, muss das Risiko durch die alternative Bauart abgeschätzt werden. Dieser Entwurf gilt nur für Typenprüfungen. Dieser Entwurf enthält keine Anforderungen an Geräte, die elektrische Energie ohne Nutzung der thermischen Energie erzeugen.
