BS EN 12831-3:2017描述了计算电池所需功率和存储容量的方法 家用热水系统（DHW）的尺寸标注。适用范围包括直接用水 加热器（无存储容量和相对较大的有效加热功率）到更大的存储空间 具有相对较小的加热功率和较大存储容量的系统。本欧洲标准适用于以下储水系统:以最小混合区为特征的储水系统（如分层储水箱） 或带有外部热交换器的储罐）:这些系统在本标准中被指定为 “充电存储系统”；带有明显混合区的储水箱热水器和温水储水箱（例如 DHW储罐（带内部热交换器），在本标准中被指定为“混合储存” 系统”； 并且有不同的用途。该范围还包括确定家用热水器能源需求的标准化方法 水本欧洲标准涵盖了建筑物的生活热水需求。DHW系统的能源需求计算适用于住宅和非住宅 建筑，建筑或建筑分区。图1显示了本标准在环境保护局标准集合中的相对位置 EN ISO 52000-1中规定的模块化结构。注1:在CEN ISO/TR 52000-2中，可以找到相同的表格，每个模块的 已发布或正在编制的相关EPB标准和随附技术报告。注2:模块代表EPB标准，尽管一个EPB标准可能涵盖多个模块 一个模块可能包含在多个EPB标准中，例如简化和详细的方法 分别地另见第2条和表A.1和B.1。表1显示了本标准在EPB标准包中的相对位置。 参考参考:EN ISO 5200 00 00-1:1:2017 ISO 5200 00 00-1:2017年EN 50404040:2015年EN 12816-16-4-4-4-4-4:2017 7-4-3-4-4-4-4-4-4-4-4-4-4-4-4-4-4:2017 7 7-7 7-7 7-7-7-12-12-12-12-12-12-12-12-12-12-12-7-7-7-7-7-7-7-7-7-12-12-12-12-12-12-12-7-12-7-12-12-12-12-7-7-7-12-7-7-12-7-7-7-12-12-12-7-12-12-7-12-12-7-7-12-7-7-12-7-12-7-12-12-12-7-7-7-7-2017EN 15378-3:2017EN15316-5:2017EN 15316-4-2:2017购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS EN 12831-3:2017 describes a method to calculate the power and the storage volume required for the dimensioning of domestic hot water systems (DHW). The applicability ranges from direct water heaters (no storage volume and a comparatively large effective heating power) to larger storage systems with a comparatively small heating power and large storage volumes.This European Standard is applicable to the following water storage systems:storage systems characterized by a minimal mixing zone, (such as stratified charging storage tanks or storage tanks with external heat exchangers): these systems are nominated in this standard as "charging storage systems";storage tank water heaters and warm water storage tanks with a pronounced mixing zone (such as DHW storage tanks with internal heat exchangers), nominated in this standard as "mixed storage systems"; and for different uses.The Scope also includes standardization methods for determining the energy need for domestic hot water. This European Standard covers the domestic hot water needs in buildings.The calculation of the energy needs for DHW-Systems applies to residential and non-residential buildings, a building or a zone of a building.Figure 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 EN ISO 52000-1.NOTE 1 In CEN 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 may cover more than one module and one module may 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.Table 1 shows the relative position of this standard within the EPB package of standards.Cross References:EN ISO 52000-1:2017ISO 52000-1:2017EN 50440:2015EN 12897:2016 EN 15316-4-3CEN ISO/TR 52000-2EN 15316-3:2017EN 15378-1:2017EN 13203-2:2015EN 806-3:2006EN 15316-4-8:2017EN 15316-4-10:2017EN 15316-1:2017EN 15316-4-4:2017EN 12831-1:2017EN 15316-4-5:2017EN 15316-4-3:2017ISO/TR 52000-2:2017EN 15316-4-1:2017EN 15316-2:2017CEN/TR 12831-4:2017EN 15459-1:2017EN 15378-3:2017EN 15316-5:2017EN 15316-4-2:2017All current amendments available at time of purchase are included with the purchase of this document.
