IEC 62862-5-2:20 22规定了大型线性菲涅耳收集器表征的要求和测试方法。 本文件涵盖了线性菲涅耳收集器的光学和热性能的测定，以及收集器单轴跟踪系统的跟踪精度。本试验方法仅用于室外试验。 本文件适用于根据附录A配备制造商提供的太阳跟踪机构的线性菲涅耳收集器。 本文件适用于现场的整个集热器现场，或作为最小单元测试单个集热器串（回路），该集热器串连接到进出散热器的主管道（流动、回流），涵盖了现场的整个温度范围。

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.
