Surface Temperatures of Window Specimens: Infrared Thermography Laboratory Measurements 窗户样品的表面温度:红外热成像实验室测量
给出了三种不同窗户试件的热侧表面的温度分布数据。将样本放置在温暖和寒冷的环境室之间,在两种不同的冬季加热标准设计条件下稳定运行。美国供暖、制冷和空调工程师协会(ASHRAE)的温度条件分别为21.1°C(70°F)和-17.8°C(0°F),在热侧和冷侧。国际标准组织(ISO)的温度条件分别为20.0°C(68.0°F)和0.0°C(32.0°F)。使用具有外部参考技术的红外热成像系统、穿越点红外温度计和热电偶编制表面温度图。红外技术允许对表面温度进行详细、非侵入性映射。 绘制了沿窗口试样中心线的垂直分布的表面温度数据。本研究旨在提高和检查计算机模拟预测窗产品冷凝阻力的准确性。为校准传输标准收集的数据表明,窗口间隙外的对流效应对于预测表面温度非常重要。单位:双引证:研讨会论文,大西洋城,2002年
Temperature distribution data are presented for the warm-side surface of three different window specimens. The specimens were placed between warm and cold environmental chambers that were operated in steady state at two different standard design conditions for winter heating. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) temperature conditions were 21.1°C (70°F) and -17.8°C (0°F) on the warm and cold sides, respectively. The International Standards Organization (ISO) temperature conditions were 20.0°C (68.0°F) and 0.0°C (32.0°F) on the warm and cold sides, respectively. Surface temperature maps were compiled using an infrared thermographic system with an external referencing technique, a traversing point infrared thermometer, and thermocouples. The infrared techniques allow detailed, nonintrusive mapping of surface temperatures. Surface temperature data are plotted for the vertical distribution along the centerline of the window specimen. This study was conducted to improve and check the accuracy of computer simulations for predicting the condensation resistance of window products. Data collected for a calibrated transfer standard showed that convective effects outside the window gap are important for predicting surface temperatures.Units: Dual
