Description

一种体感温度测量方法
技术领域
本发明公开了一种体感温度测量方法,具体地说是一种通过测量空气的温度、湿度和风速等参数,考虑了人在运动前后结合风速、湿度的体感温度会有较大变化,所以本方法适用于人在多种场景下的体感温度测量,以便调整使室内环境使之处于一种舒适的状态。
背景技术
目前,一般的体感测量方法只考虑到空气温度、湿度和风速等因素的综合影响,有的方法则结合了光照强度与辐射强度。这些测量方法有的过于复杂不方便测量计算,有的过于简单,数据偏离人体实际体感温度较多,结果不准确,当室内使用这些方法得出的体感温度值来调控环境,往往无法将室内环境调整至一种使人感觉舒适的状态。
发明内容
本发明的目的在于避免现有技术的不足,从而提供一种计算方式简单,结果准确的体感温度测量方法。
本发明的体感温度测量方法,其特征是按照下述方式进行的:
(1)测量所处环境的空气流速V;
(2)计算得出风速指数V0: V0=1.76+1.4V0.75
其中1.76为风速的常量,1.4V0.75为空气流速在室内流通的增量值。
(3)测量特定时间范围内的人体运动量S和个人运动量标准Sn、所处环境的空气相对湿度H;
(4)根据S与Sn的大小关系计算推导出运动变量St
1)S>Sn ,St=0.75
2)S=Sn ,St=0.5
3)S<Sn ,St=0.25
4)S = 0 ,St=0
(5)计算推导出运动指数S0: S0=0.75*St*(1-H/100)/2*(V-1)/5
其中0.75为运动常量。
(6)测量所处环境的空气温度T;
(7)计算体感温度Tper: Tper=37-(37-T)/(0.68-0.0014H+1/V0-S0)-0.29T*(1-H/100)
其中37为人体温度常量。
附图说明
图1是本发明的测量计算流程图。
具体实施方式
1.一种体感温度测量方法,其特征在于是按照下述方式进行的:
(1)测量所处环境的空气流速V;
(2)计算得出风速指数V0: V0=1.76+1.4V0.75
其中1.76为风速的常量,1.4V0.75为空气流速在室内流通的增量值。
(3)测量特定时间范围内的人体运动量S和个人运动量标准Sn、所处环境的空气相对湿度H;
(4)根据S与Sn的大小关系计算推导出运动变量St: 1)S>Sn ,St=0.75
2)S=Sn,St=0.5
3)0<S<Sn,St=0.25
4)S=0,St=0
(5)计算推导出运动指数S0: S0=0.75*St*(1-H/100)/2*(V-1)/5
其中0.75为运动常量。
(6)测量所处环境的空气温度T;
(7)计算体感温度Tper: Tper=37-(37-T)/(0.68-0.0014H+1/V0-S0)-0.29T*(1-H/100)
其中37为人体温度常量。
其中个人运动量标准是根据个人的身体状况分为少量运动、适量运动和大量运动三个标准,人在运动过后产生出汗现象,根据不同人群的出汗多少,将运动变量St取为小于1的四个等级的修正值,除个别人群外,修正后的体感温度更贴近真实体感温度。
人体运动过后会产生出汗现象,空气流动会加快皮肤表面汗液的蒸发,使体感温度Tper降低,当空气相对湿度H增大,空气流速v对体感温度的影响会减小,以室内环境空气温度28℃,相对湿度40%,空气流速0.3米/秒,在少量运动时,体感温度为:风速指数:V0=1.76+1.4*0.30.75=2.3275
运动指数:S0=0.75*0.25*(1-40/100)/2*(0.3-1)/5=-0.0079
Tper=37-(37-28)/(0.68-0.0014*40+1/2.3275+0.0079)-0.29*28*(1-40/100)
=23.6℃
即体感温度为23.6℃,远低于室内环境空气温度,当室内环境相对湿度H增加到90%,体感温度Tper增大到27℃,这个结果与室内人的感觉完全相同,即风速较小的时候,运动后的人的体感温度会高出没有运动的人的体感温度,当风速变大,运动后的人的体感温度会随着风速的变大而减小,甚至低于没有运动的人的体感温度,但随着湿度的增加,风速对体感温度的影响减小,这个结果符合人体的正常感受。
