热调节暖体假人在着装舒适性评价中的应用现状

为丰富暖体假人评价服装热湿舒适性的测评参数，基于对恒皮温、恒热流、热舒适3 种模式的原理及应用分析指出，有必要将体温调节模型引入假人系统，弥补常见模式无法模拟人体热调节的缺陷。以Fiala 模型为例，分析了生物热方程为基础的被动系统、包含四大热调节机制的主动系统构成及热调节假人系统的耦合机制。结合预测平均投票值及加州大学伯克利分校热感觉模型等，热调节假人可实现对人体稳态及瞬态热感觉的预测，从人体角度评价服装舒适性。对比热调节数值假人和暖体假人，前者灵活性更强，但需要考虑的因素过多，模拟准确性低于后者。

Application status of thermoregulatory mode in clothing comfort evaluation with thermal manikin

In order to expand evaluation system of thermal manikin, considering the application status of conventional modes including constant skin temperature, constant heat flux and thermal comfort, it indicates that it has great necessity to integrate human thermoregulatory system into thermal manikin. In doing so, the shortcoming incapability of simulating human thermal regulation could be offset. Taking Fiala model as an example, the controlled system based on bio-heat equation and controlling system with four regulation mechanisms were analyzed. Combined with predicted mean vote (PMV), University of Clifornia of Berkeley ( UCB) and other subjective thermal sensation models, thermoregulatory manikins could make predictions of both steady and transient thermal sensations, and evaluate comfort from the perspective of human beings. By comparisons between thermoregulatory numerical manikins and thermoregulatory manikins, it is concluded that the former has better flexibility, but has more influencing factors. Therefore, the latter has better accuracy.
