Thermal solar systems and components - Custom built systems - Part 3: Performance test methods for solar water heater stores
This European Standard specifies test methods for the performance characterization of stores which are intended for use in small custom built systems as specified in EN 12977 1.
Stores tested according to this document are commonly used in solar hot water systems. However, the thermal performance of all other thermal stores with water as a storage medium can also be assessed according to the test methods specified in this document.
The document applies to stores with a nominal volume between 50 l and 3 000 l.
This document does not apply to combistores. Performance test methods for solar combistores are specified in EN 12977 4.
Thermische Solaranlagen und ihre Bauteile - Kundenspezifisch gefertigte Anlagen - Teil 3: Leistungsprüfung von Warmwasserspeichern für Solaranlagen
Diese Europäische Norm legt Prüfverfahren für die Beschreibung der Leistung von Warmwasserspeichern (im
Folgenden Speicher genannt) fest, die zur Verwendung in kleinen kundenspezifisch gefertigten Solaranlagen
nach EN 12977-1 bestimmt sind.
Die nach dem vorliegenden Dokument geprüften Speicher werden häufig in solaren Warmwasseranlagen
verwendet. Jedoch kann auch die thermische Leistung aller anderen Wärmespeicher, bei denen Wasser als
Speichermedium zum Einsatz kommt nach den in diesem Dokument festgelegten Prüfverfahren bewertet
werden.
Dieses Dokument gilt für Speicher mit einem Nennvolumen zwischen 50 l und 3 000 l.
Dieses Dokument gilt nicht für Kombispeicher. Die Verfahren zur Leistungsprüfung von Solar-Kombispeichern
sind in EN 12977-4 festgelegt.
Installations solaires thermiques et leurs composants - Installations assemblées à façon - Partie 3: Méthodes d'essai des performances des dispositifs de stockage des installations de chauffage solaire de l'eau
La présente Norme européenne spécifie des méthodes d'essai pour la caractérisation des performances des
dispositifs de stockage destinés à être utilisés dans de petites installations assemblées à façon, comme
spécifié dans l’EN 12977-1.
Les dispositifs de stockage soumis à essai conformément au présent document sont couramment utilisés
dans les installations solaires de production d'eau chaude. Toutefois, les performances thermiques de tous
les autres dispositifs de stockage thermique où l’eau est utilisée comme milieu de stockage peuvent
également être évaluées conformément aux méthodes d’essai spécifiées dans le présent document.
Le document s’applique aux dispositifs de stockage dont le volume nominal est compris entre 50 l et 3 000 l.
Le présent document ne s’applique pas aux dispositifs de stockage combinés. Les méthodes d’essai relatives
aux performances des dispositifs de stockage combinés sont spécifiées dans l’EN 12977-4.
Toplotni sončni sistemi in sestavni deli - Neserijsko izdelani sistemi - 3. del: Določanje preskusnih metod za hranilnike toplote, ogrevane s soncem
Ta evropski standard določa preskusne metode za delovanje hranilnikov, ki so namenjeni za uporabo v majhnih neserijsko izdelanih sistemih iz standarda FprEN 12977-1. Hranilniki, ki se preskušajo v skladu s tem dokumentom, se običajno uporabljajo za sončne toplovodne sisteme. Vendar se lahko na podlagi preskusnih metod iz tega dokumenta oceni tudi toplotna učinkovitost vseh drugih hranilnikov toplote, ki kot sredstvo shranjevanja uporabljajo vodo. Dokument se uporablja za hranilnike z nominalno prostornino od 50 do 3000 l. Ta dokument se ne uporablja za kombinirane hranilnike. Preskusne metode za delovanje sončnih kombiniranih hranilnikov so določene v standardu FprEN 12977-4.
