标准摘要
[中文适用范围]： ISO 22975的本部分适用于测定在家用热水系统或联合循环系统的典型条件下运行的通风平板集热器的选择性太阳能吸收器的长期性能和使用寿命。 ISO 22975 的这一部分根据其光学性能的变化指定了太阳能吸收器的失效标准。 考虑的光学特性是太阳吸收率和热发射率。 ISO 22975 的这一部分规定了耐久性测试的方法，重点是耐高温、吸收体表面的水凝结以及高湿度和二氧化硫含量的空气。 [外文原描述]： ISO 22975-3:2014 is applicable to the determination of the long term behaviour and service life of selective solar absorbers for use in vented flat plate solar collectors working under conditions corresponding to that in a typical solar domestic hot water system or combisystem. ISO 22975-3:2014 specifies a failure criterion of a solar absorber based on changes in optical performance of the absorber. The optical properties of interest are solar absorptance and thermal emittance. ISO 22975-3:2014 specifies durability testing procedures focused on resistance to high temperatures and condensation of water on the absorber surface as well as high humidity in the presence of sulfur dioxide.
