研究如何使用计算机模拟来确定窗框U形因子。对窗框性能的计算机模拟值和七种不同窗户的详细测试进行了详细比较。然后使用相同的计算机模拟技术确定代表性的框架U型系数，涵盖所有窗户材料类型和操作风格。声明这些结果将用于扩展1993年ASHRAE手册-基础第27章的表5（以前的表13）。关键词:模型，计算，计算机，性能，窗口，窗框，透射率，比较，测试。单位:双引文:研讨会，ASHRAE交易1993，第99卷，pt。1.

Examines the use of computer simulation to determine window frame U-factors. Makes s detailed comparison between computer-simulated values of window frame performance and detailed testing for seven different windows. Then uses the same computer simulation technique to determine representative frame U-factors covering the full range of window material types and operating styles. States these results will be used to expand Table 5 (previously Table 13) of chapter 27 of the1993 ASHRAE Handbook - Fundamentals.KEYWORDS: Models, calculating, computers, performance, windows, window frames, transmittance, comparing, testing.Units: Dual
