Energy performance of buildings - Ventilation for buildings - Part 15: Calculation of cooling systems (Module M4-7) - Storage
This European Standard specifies a calculation method for the energy performance of storage systems used for ventilation systems. It takes into account the energy performance of storage systems using water from phase change material (PCM) to store cooling energy. This standard presents a general method applicable to the different technologies of water-based storage systems or PCM related controls systems. It does not cover the cooling emission, distribution and generation that are covered by EN 15316 2, EN 15316 3 and EN 16798-13 respectively.
The standard covers typically hourly time steps but can be adapted to different time steps accordingly with the scenarios used for energy use and energy delivered or to bin method.
A simplified method is provided for monthly or annual time step.
This standard does not cover:
- the cooling emission, distribution and generation systems; or
- sizing or inspection of such storage systems.
Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in prEN ISO 52000 1:2015.
NOTE 1 In prCEN ISO/TR 52000 2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation.
NOTE 2 The modules represent EPB standards, although one EPB standard might cover more than one module and one module might be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Tables A.1 and B.1.

Energetische Bewertung von Gebäuden - Lüftung von Gebäuden - Teil 15: Berechnung von Kühlsystemen (Modul M4-7) - Speicherung
Diese Europäische Norm legt ein Verfahren zur Berechnung der Gesamtenergieeffizienz von für Lüftungs-anlagen genutzten Speichersystemen fest. Sie berücksichtigt dabei die Gesamtenergieeffizienz von Speicher¬systemen, bei denen Wasser als Phasenwechselmaterial (PCM, en: phase change material) genutzt wird, um Kühlenergie zu speichern. Diese Norm stellt ein allgemeines Verfahren vor, das auf verschiedene Technologien von wasserbasierten Speichersystemen oder PCM bezogene Kontrollsysteme angewandt werden kann. Sie deckt nicht die Kälteemission, Verteilung und Erzeugung ab; diese werden jeweils von EN 15316 2, EN 15316 3 und EN 16798 13 abgedeckt.
Die Norm deckt typischerweise den stündlichen Zeitschritt ab, kann jedoch entsprechend den für den Energieverbrauch und die zugeführte Energie genutzten Szenarios an andere Zeitschritte oder an den Temperaturklassenansatz (Bin Methode) angepasst werden.
Für den monatlichen oder jährlichen Zeitschritt ist ein vereinfachtes Verfahren dargestellt.
Diese Norm behandelt nicht:
— Kälteemissions , Verteilungs und Erzeugungssysteme; oder
— die Bemessung oder Inspektion derartiger Speichersysteme.
Tabelle 1 zeigt die relative Position dieser Norm innerhalb des EPB Normenpakets im Kontext der in EN ISO 52000 1:2017 dargelegten modularen Struktur.
ANMERKUNG 1 In CEN ISO/TR 52000 2 findet sich die gleiche Tabelle mit den Nummern (für jedes Modul) der jeweiligen EPB Normen und den dazugehörigen technischen Berichten, die bereits veröffentlicht wurden oder sich in der Erarbeitung befinden.
ANMERKUNG 2 Die Module repräsentieren EPB Normen, auch wenn eine EPB Norm ggf. mehr als ein Modul abdeckt und ein Modul durch mehr als eine EPB Norm abgedeckt werden kann, etwa jeweils durch ein vereinfachtes und ein detailliertes Verfahren. Siehe auch Abschnitt 2 und Tabellen A.1 und B.1
Performance énergétique des bâtiments - Ventilation des bâtiments - Partie 15 : Calcul des systèmes de refroidissement (Module M4-7) - Stockage
La présente Norme européenne spécifie une méthode de calcul de la performance énergétique des systèmes de stockage utilisés pour les systèmes de ventilation. Elle prend en compte la performance énergétique des systèmes de stockage utilisant l'eau des matériaux à changement de phase (MCP) pour stocker de l'énergie de refroidissement. La présente norme présente une méthode générale, applicable aux différentes technologies des systèmes de stockage utilisant l’eau ou des systèmes de régulation relatifs aux matériaux à changement de phase.

NOTE 1 The value of QC;sto;in can be positive or negative. In the negative case, the generation system is required to extract from the storage (charging mode). Recoverable heat QC;sto,ls,rbl is the recoverable heat for heating in the calculation interval. NOTE 2 This value could be negative as the temperature of the storage unit can be lower than the ambient temperature. 6.2 Calculation time interval and calculation period The method described in the following clauses are suitable for the following calculation time steps: — hourly (6.4.3); — monthly (6.5); and — yearly (6.5). For this method, the output time step is the same as the input time step. This method does not take into account any dynamic effect (the transformation is based only on the variation of enthalpy in the storage within the time step, without delay in the storage or release of heat). If the input data are available with a shorter time step than the output: — the sum is taken proportionally with extensive properties like energy; and — the time averaged value is taken for intensive properties like temperature. 6.3 Calculation period The length of the calculation period, also depending on the calculation interval (e.g. month, hour), is given in EN ISO 52000-1, (M1-9).
