GB/T 4271-2000 in English

《GB/T 4271-2000平板型太阳集热器热性能试验方法》由TC20（全国能源基础与管理标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准规定了平板型太阳集热器稳态和准稳态热性能的试验方法及计算程序。试验方法包括在室外自然太阳辐照下的试验和在室内模拟太阳辐照下的试验。本标准适用于带压力降、有玻璃盖板、传热工质为液体的平板型太阳集热器。本标准不适用于储热器与集热器为一体的储热式太阳集热器，也不适用于未装有玻璃盖板的和跟踪聚焦的太阳集热器。

Scope

This standard specifies the test methods and calculation procedures for the steady-state and quasi-steady-state thermal performance of flat-plate solar collectors. The test methods include tests under outdoor natural solar radiation and indoor tests under simulated solar radiation. This standard applies to flat-plate solar collectors with pressure drop, glass cover, and liquid heat transfer medium (hereinafter referred to as solar collectors or collectors). This standard does not apply to thermal storage solar collectors where the heat storage and collector are integrated, nor does it apply to solar collectors that are not equipped with glass cover plates and track focus.
