标准摘要
[中文适用范围]： 本国际标准规定了一种评估太阳能热水器年度能源性能的方法，该方法结合了组件性能的测试结果和数学模型，以确定在指定天气和负载条件下的年度负载周期任务性能。该程序适用于带有整体备份或预热进入常规储罐或瞬时热水器的太阳能热水器，以及整体集热器储罐热水器。本国际标准中规定的系统运行要求仅用于确定家用热水器的年度性能评级。本国际标准中没有产品设计和运行要求。 [外文原描述]： ISO 9459-4:2013 specifies a method of evaluating the annual energy performance of solar water heaters using a combination of test results for component performance and a mathematical model to determine an annual load cycle task performance under specified weather and load conditions. The procedure is applicable to solar water heaters with integral backup or preheating into a conventional storage or instantaneous water heater and to integral collector storage water heaters. System operating requirements specified in ISO 9459-4:2013 are for the purpose of determining an annual performance rating for domestic water heaters. There are no product design or operation requirements in ISO 9459-4:2013.
