A Comprehensive Data Base for Estimating Clothing Insulation 估算服装隔热性能的综合数据库
ASHRAE标准55-1981和ASHRAE手册第8章--1981基本原则规定了大多数人在不同的服装隔热和代谢活动水平下可以接受的热环境条件。这些文件的使用者有必要确定哪些类型的衣服提供不同程度的绝缘。本研究的目的是(1)扩展目前室内环境中常用服装和服装套装的绝缘(clo)值数据库;(2)开发和比较不同的估计服装绝缘的方法。在气候控制室内,使用一个站立的电加热人体模型,测量了115件不同服装和60个代表性服装的clo值。回归分析用于将许多变量与服装和整体隔热性能联系起来。此外,还开发了一种新的计算机模型,用于计算局部和全身热量损失(或衣物隔热)。 确定并讨论了预测方程和模型的相对精度。单位:SICitation:ASHRAE Transactions,1985年,第91卷,pt。你好,檀香山2A
ASHRAE Standard 55-1981and Chapter 8 of ASHRAEHandbook--1981 Fundamentalsspecify the environmental conditions that are thermally acceptable to most people at different levels of clothing insulation and metabolic activity. It is necessary for users of these documents to determine what types of clothing provide different amounts of insulation. The purpose of this study was (1) to expand the current data base of insulation (clo) values for garments and clothing ensembles commonly worn in indoor environments and (2) to develop and compare different methods for estimating clothing insulation. The clo values of 115 different garments and 60 representative ensembles were measured using a standing, electrically heated manikin in a climate-controlled chamber. Regression analysis was used to relate a number of variables to garment and ensemble insulation. A new computer model, which calculates local and total body heat loss (or clothing insulation), was developed also. The relative accuracy of the predictive equations and model was determined and discussed.Units: SI
