Thermal solar systems and components - Custom built systems - Part 4: Performance test methods for solar combistores
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 combisystems. However, the thermal performance of all other thermal stores with water as a storage medium (e.g. for heat pump systems) can be also assessed according to the test methods specified in this document.
This document applies to combistores with a nominal volume up to 3 000 l and without integrated burner.
NOTE This document is extensively based on references to EN 12977 3:2012.
Thermische Solaranlagen und ihre Bauteile - Kundenspezifisch gefertigte Anlagen - Teil 4: Leistungsprüfung von Warmwasserspeichern für Solaranlagen zur Trinkwassererwärmung und Raumheizung (Kombispeicher)
Diese Europäische Norm legt Prüfverfahren für die Beschreibung der Leistung von Warmwasserspeichern (im Folgenden Speicher genannt) fest, die zur Verwendung in kleinen kundenspezifisch gefertigten Solaranla¬gen nach EN 12977-1 bestimmt sind.
Die nach dem vorliegenden Dokument geprüften Speicher werden häufig in solaren Kombianlagen eingesetzt. Jedoch kann auch die thermische Leistung aller anderen Wärmespeicher, bei denen Wasser als Speicher¬medium zum Einsatz kommt (z. B. Wärmepumpenanlagen), nach den in diesem Dokument festgelegten Prüf¬verfahren bewertet werden.
Das vorliegende Dokument gilt für Kombispeicher mit einem Nennvolumen von bis zu 3 000 l ohne integrier¬ten Brenner.
ANMERKUNG Das vorliegende Dokument nimmt weitgehend Bezug auf EN 12977 3:2011.
Installations solaires thermiques et leurs composants - Installations assemblées à façon - Partie 4: Méthodes d'essai de performances des dispositifs de stockage combinés pour installations de chauffage solaires
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 indiqué
dans l’EN 12977-1.
Les dispositifs de stockage soumis à essai conformément au présent document sont couramment utilisés dans les
installations solaires combinées. Cependant, la performance thermique de tous les autres dispositifs de stockage
thermiques utilisant de l’eau comme support de stockage (par exemple pour des installations de pompe à chaleur)
peut également être évaluée conformément aux méthodes d’essai spécifiées dans le présent document.
Le présent document s’applique aux dispositifs de stockage combinés ayant un volume nominal jusqu’à 3000 litres
et sans brûleur intégré.
NOTE Le présent document est principalement basé sur les références de l’EN 12977-3:2012.
Toplotni sončni sistemi in sestavni deli - Neserijsko izdelani sistemi - 4. del: Preskusne metode delovanja sončnih zbiralnikov
Ta evropski standard določa preskusne metode za delovanje hranilnikov, ki so namenjeni za uporabo v majhnih neserijsko izdelanih sistemih iz standarda EN 12977-1. Hranilniki, ki se preskušajo v skladu s tem dokumentom, se običajno uporabljajo v sončnih kombiniranih sistemih. Vendar se lahko na podlagi preskusnih metod iz tega dokumenta oceni tudi toplotna učinkovitost vseh drugih hranilnikov toplote, ki kot sredstvo shranjevanja uporabljajo vodo (npr. za sisteme toplotnih črpalk). Ta dokument se uporablja za kombinirane hranilnike z nominalno prostornino do 3000 l in brez vgrajenega gorilnika.

NOTE 3 For additional information about the test methods for the performance characterisation of stores see EN 12977-3 and [1] in Bibliography.
For symbols and abbreviations, refer to EN 12977-3:2012. 5 Store classification Solar combistores are classified by distinction between different charge and discharge modes. Five groups are defined as shown in Table 1. SIST EN 12977-4:2012
NOTE 1 All stores may have one or more additional electrical heating elements. NOTE 2 Stores that can be charged or discharged directly and indirectly (e.g. a store of a space heating system with an internal heat exchanger for the preparation of domestic hot water) can belong to more than one group. In this case, the appropriate test procedures or the assignment to one of the groups respectively, should be chosen depending on its mode of operation. 6 Laboratory store testing 6.1 Requirements on the testing stand 6.1.1 General The hot water store shall be tested separately from the whole solar system on a store-testing stand. The testing stand configuration shall be determined by the classification of the combistores as described in Clause 5. An example of a representative hydraulic testing stand configuration is shown in EN 12977-3:2012, Figure 1 and Figure 2. An appropriate test facility consists of two charge loops as shown in EN 12977-3:2012, Figure 1 and two discharge loops as shown in EN 12977-3:2012, Figure 2. 6.1.2 Measuring data and measuring procedure The requirements specified in EN 12977-3:2012, 6.1.2 shall be fulfilled. 6.2 Installation of the store 6.2.1 Mounting The store shall be mounted on the testing stand according to the manufacturer's instructions. The temperature sensors used for measuring the inlet and outlet temperatures of the fluid used for charging and discharging the storage device, shall be placed as near as possible at least 200 mm to the inlet and outlet connections of the storage device. The installation of the temperature sensors inside the pipes shall be done according to approved methods of measuring temperatures. If there is/are more than one pair of charging and/or discharging inlet or outlet connections, then only one may be connected to the testing stand (at the same time) while the other(s) shall be closed. The pipes between the store and the temperature sensors shall be insulated according to EN 12828. SIST EN 12977-4:2012
Connections of the store which do not lead to the charge or discharge circuit of the testing stand shall be closed, and not connected heat exchangers shall be filled up with water.
