本文件适用于生产生活热水的太阳能燃气设备。它适用于作为单个单元销售的系统或完全指定的系统: -气体热输入不超过70千瓦； -热水储罐容量不超过500升； -配备至少一个太阳能集热器； -就太阳能液压回路而言，被视为强制循环系统（定义符合EN ISO 9488:1999）。 附录E（规范性附录）中描述了本文件涵盖的设备。 根据EN ISO 9488:1999给出的定义，本文件不适用于热虹吸管或整体收集器储罐系统。 注:原则上，热虹吸式太阳能预热系统和整体收集器储罐预热系统的能耗也可根据本文件进行评估。为此目的，一个合适的程序是，根据ISO 9459，使用数值系统模型和热太阳能系统性能参数，在本标准规定的参考条件下，计算从热太阳能系统抽取的生活热水的温度水平- 5.根据从仓库取出的热水的温度水平，确定燃气器具的能耗。可通过计算或根据FprEN 13203 2:2022进行试验，并使用从仓库中取出的热水温度代替冷水入口温度来进行测定。 本文件不用于评估以下性能: -太阳能集热器，应符合EN 12975-1:2006+A1:2010和EN 12975-2:2006； -应符合EN 12976的热太阳能系统和组件- 1:2021和EN 12976-2:2019。 FprEN 13203-1:2021从定性和定量的角度阐述了为选定的各种用途提供生活热水的性能。它还提供了向用户展示信息的功能。 本文件阐述了一种评估太阳能支持设备的能源性能的方法。它规定了每个家庭热水使用、厨房、淋浴、浴缸以及这些的组合的几个每日水龙头周期，以及相应的测试程序，包括有关可用太阳辐射的信息。 它可以比较不同燃气设备的能源性能，并与用户的需求相匹配。

This document is applicable to solar supported gas-fired appliances producing domestic hot water. It applies to a system marketed as single unit or a fully specified system that: - has a gas heat input not exceeding 70 kW; - has a hot water storage tank capacity not exceeding 500 l; - is equipped with at least one solar collector; - is, with regard to the solar hydraulic circuit, considered as a forced circulation system (definition according to EN ISO 9488:1999). The appliances covered by this document are described in Annex E (normative). This document does not apply to thermo-siphon or integral collector storage tank systems according to definitions given by EN ISO 9488:1999. NOTE In principle, the energy consumption of thermo-siphon solar preheat systems and integral collector storage tank preheat systems can also be assessed based on this document. One appropriate procedure for that purpose is to calculate the temperature level of the domestic hot water withdrawn from the thermal solar system for the reference conditions specified in this standard by using the numerical system model and the thermal solar system performance parameters according to ISO 9459-5. Based on the temperature level of the hot water withdrawn from the store the energy consumption of the gas appliance is determined. This determination can either be done by means of calculations or by performing a test according to EN 13203 2:2022 and using instead of the cold water inlet temperature the hot water temperature withdrawn from the store. This document is not intended to assess the performance: - of the solar collector(s), which should comply with EN 12975-1:2006+A1:2010 and EN 12975-2:2006; - of thermal solar systems and components, which should comply with EN 12976-1:2021 and EN 12976-2:2019. EN 13203-1:2015 sets out in qualitative and quantitative terms the performance in delivery of domestic hot water for a selected variety of uses. It also gives a presenting the information to the user. The present document sets out a method for assessing the energy performance of a solar supported appliance. It specifies a few daily tapping cycles for each domestic hot water use, kitchen, shower, bath and a combination of these, together with corresponding test procedures including information about the available solar radiation. It enables the energy performances of different gas-fired appliances to be compared and matched to the needs of the user.
