标准摘要
[中文适用范围]： 本部分IEC 62862规定了大型线性菲涅耳集热器的特性和测试方法的要求。 本文件涵盖了线性菲涅耳集热器的光学和热性能测定，以及集热器单轴跟踪系统的跟踪精度。此测试方法仅适用于户外测试。 本文件适用于根据附录A配备制造商提供的太阳跟踪机制的线性菲涅耳集热器。 本文件中的测试方法不适用于任何在流体发生相变的操作条件下的集热器。尽管本文件的原理也可应用于相变集热器，但所需的传感器（焓、流量、温度）未在本文件中描述。 本文件适用于整个集热器现场或作为最小测试单元连接到主管道（流向、回流）的单个集热器串（回路），覆盖整个温度范围。 [外文原描述]： IEC 62862-5-2:2022 specifies the requirements and the test methods for the characterization of a large-size linear Fresnel collector. This document covers the determination of optical and thermal performance of linear Fresnel collectors, and the tracking accuracy of the collector one-axis tracking system. This test method is for outdoor testing only. This document applies to linear Fresnel collectors according to Annex A equipped with the manufacturer-supplied sun tracking mechanism. This document applies to the whole collector field in-situ or as a minimum unit to be tested to an individual collector string (loop) connected to the main piping (flow, return flow) to and from a heat sink, covering the full temperature range of the field.
