门窗的热性能. 用太阳模拟器测定太阳能得热系数

[中文适用范围]： 本文件规定了完整门窗太阳得热系数的测量方法。 本文件适用于 a) 具有各种类型的玻璃窗（玻璃或塑料；单层或多层玻璃窗；有或没有低辐射率涂层，以及充满空气或其他气体的空间）的门窗，b) 具有不透明面板的门窗，c)具有各种类型的框架（木质、塑料、金属，带或不带隔热层或任何材料组合），d）具有各种类型的遮阳装置（百叶窗、屏幕、薄膜或任何具有遮阳效果的附件），e）具有各种类型主动式太阳能开窗系统[建筑一体化光伏系统（BIPV）或建筑一体化太阳能集热器（BIST）]。 本文件不包括以下内容： a) 建筑构件（如屋檐、套墙等）的遮阳效果； b) 室内外漏风引起的热量传递； c) 双窗和连体窗空气空间的通风； d) 窗框或门框与建筑围护结构其余部分之间的折口或接缝处的热桥效应。 本文件不适用于以下情况： a) 非垂直窗户； b) 幕墙； c) 工业、商业和车库门。 [外文原描述]： ISO 19467:2017 specifies a method to measure the solar heat gain coefficient of complete windows and doors. ISO 19467:2017 applies to windows and doors a) with various types of glazing (glass or plastic; single or multiple glazing; with or without low emissivity coatings, and with spaces filled with air or other gases), b) with opaque panels, c) with various types of frames (wood, plastic, metallic with and without thermal barrier or any combination of materials), d) with various types of shading devices (blind, screen, film or any attachment with shading effects), e) with various types of active solar fenestration systems [building-integrated PV systems (BIPV) or building-integrated solar thermal collectors (BIST)]. ISO 19467:2017 does not include the following: a) shading effects of building elements (e.g. eaves, sleeve wall, etc.); b) heat transfer caused by air leakage between indoors and outdoors; c) ventilation of air spaces in double and coupled windows; d) thermal bridge effects at the rebate or joint between the window or door frame and the rest of the building envelope. ISO 19467:2017 does not apply to the following: a) non-vertical windows; b) curtain walls; c) industrial, commercial and garage doors.
