Gas-fired domestic appliances producing hot water - Part 4: Assessment of energy consumption of gas combined heat and power appliances (mCHP) producing hot water and electricity
This document is applicable to gas-fired mCHP appliances producing domestic hot water and electricity. The electricity is generated in a process linked to the production of useful heat.
It applies to a mCHP appliances marketed as single unit or as a package fully specified by a manufacturer that have:
- a gas heat input not exceeding 400 kW;
- an electrical output not exceeding 50 kW;
- a hot water storage capacity (if any) not exceeding 2 000 l.
EN 13203-1:2015 sets out in qualitative and quantitative terms the performance in delivery of domestic hot water for a variety of uses. It also gives a system for presenting the information to the user.
The present document sets out a method for assessing the energy performance of gas fired mCHP appliances. It defines several daily tapping cycles for each domestic hot water use, kitchen, shower, bath and a combination of these, together with corresponding test procedures, enabling the energy performances of different gas-fired appliances to be compared and matched to the needs of the user.
When the mCHP generator does not supply domestic hot water in the summer period, the present standard is not applicable. EN 13203-2:2022 is used for performance assessment of these generators.
Gasgeräte für die häusliche Warmwasserbereitung - Teil 4: Bewertung des Energieverbrauchs von Gas-Kraft-Wärme-Kopplungsgeräten (µKWK), die Warmwasser und Strom erzeugen
Dieses Dokument ist auf gasbefeuerte Geräte mit Mikro-Kraft-Wärme-Kopplung (µKWK-Geräte) anwendbar, die sanitäres Warmwasser und elektrische Energie bereitstellen. Die elektrische Energie wird in einem Prozess erzeugt, der mit der Bereitstellung von Nutzwärme verbunden ist.
Es gilt für µKWK-Geräte, die als einzelne Einheit oder als vom Hersteller umfassend beschriebenes System vertrieben werden und die:
— eine Gaswärmebelastung von höchstens 400 kW haben,
— eine elektrische Leistung von 50 kW nicht überschreiten und
— ein Warmwasser-Speichervolumen (sofern vorhanden) von höchstens 2 000 l haben.
EN 13203 1:2015 legt mehrere qualitative und quantitative Leistungsstufen für die sanitäre Warmwasserbereitung für eine Auswahl von Benutzungsarten fest. Sie enthält zudem ein System zur Bereitstellung von Informationen für den Nutzer.
Das vorliegende Dokument legt ein Verfahren zur Bewertung des Energieverhaltens von gasbefeuerten µKWK-Geräten fest. Es legt mehrere tägliche Zapfprogramme für jede häusliche Warmwasserverwendung in der Küche, zum Duschen und Baden sowie für Kombinationen dieser Verwendungsarten und die entsprechenden Prüfverfahren fest, mit denen sich das Energieverhalten unterschiedlicher gasbefeuerter Geräte vergleichen und auf die Bedürfnisse des Nutzers ausrichten lässt.
Wenn der µKWK-Generator im Sommer kein sanitäres Warmwasser liefert, ist diese Norm nicht anwendbar. EN 13203 2:2022 dient zur Bewertung der Leistung dieser Generatoren.
Appareils domestiques produisant de l’eau chaude sanitaire utilisant les combustibles gazeux - Partie 4 : Évaluation de la consommation énergétique des appareils à gaz de production combinée de chaleur et d’électricité (mCHP) produisant de l’eau chaude et de l’électricité
Le présent document s’applique aux appareils de micro-cogénération utilisant des combustibles gazeux pour produire de l’eau chaude sanitaire et de l’électricité. L’électricité est produite par un procédé permettant la valorisation d’une énergie thermique.
Il s’applique aux appareils de micro-cogénération commercialisés comme une seule unité ou comme un produit combiné entièrement spécifié par le fabricant, qui ont :
- un débit calorifique de gaz inférieur ou égal à 400 kW ;
- une puissance électrique inférieure ou égale à 50 kW ;
- une capacité de stockage en eau chaude (le cas échéant) inférieure ou égale à 2 000 l.
L’EN 13203 1:2015 définit en termes qualitatifs et quantitatifs la performance en puisage d’eau chaude sanitaire pour une variété d’usages. Elle fournit également un système pour présenter les informations à l’utilisateur.
Le présent document définit une méthode pour déterminer les performances énergétiques des appareils de micro-cogénération utilisant des combustibles gazeux. Il définit plusieurs cycles de puisage journaliers pour l’usage d’eau chaude sanitaire, cuisine, douche, bain et une combinaison de ces derniers, ainsi que les modes opératoires d’essai correspondants, afin de pouvoir comparer les performances énergétiques des différents appareils utilisant les combustibles gazeux et de les adapter aux besoins de l’utilisateur.
La présente norme n’est pas applicable lorsque le micro-cogénérateur (mCHP) ne fournit pas d’eau chaude sanitaire en période estivale. L’EN 13203-2:2022 est utilisée pour déterminer les performances de ces générateurs.
