摘要
根据室内热环境人体舒适性具有的不绝对、模糊的特点,研制出了一种多变量模糊舒适度评价仪表.仪表以室内空气的温度、相对湿度、流速为输入变量,以模糊综合评判方法为原理,以ADμC812单片机为硬件电路核心,给出了各影响因素的权重系数及各语言变量语言值的化分,对于温度、相对湿度影响因素具有耦合关系问题,通过不同温度区间采用不同的权重系数及不同的语言值的化分的方法解决,能够实现数据采集,运算合成及解耦合,得出评价结论的功能,实验结果表明:该仪表具有较高的可信度,是对室内热环境舒适性作出评价的一种有效工具.
A multi-variable comfort index fuzzy evaluation instrument was developed according to non-absolute and fuzzy features of indoor thermal environment human comfort index. Based on fuzzy evaluation method and using single-chip-unit ADμC812 as hardware core, the instrument adopts indoor temperature, relative humidity and flow rate as input variables. The weight of every affecting factors and partition of every linguistic variable were given. The coupling of temperature and relative humidity was resolved through adopting different weights and partition on linguistic variable in different temperature domains. The instrument can realize such functions as data collection, operation synthesis, decoupling and calculating evaluation value. Test results indicate that its evaluation has higher reliability. It is an effective tool to evaluate indoor thermal comfort index and has wider application prospect.
