In this study, three transient environmental conditions consisting of one high-temperature phase within two low-temperature phases were developed, thus creating a temperature rise followed by a temperature fall. Twenty-four subjects (including 12 males and 12 females) were recruited and they underwent all three test scenarios. Skin temperature on seven body parts were measured during the whole period of the experiment. Besides, thermal sensation was investigated at specific moments by questionnaires. Thermal sensation models including PMV model, Fiala model and the Chinese model were applied to predict subjects' thermal sensation with comparisons carried out among them. Results show that most predicated thermal sensation by Chinese model lies within the range of 0.5 scale of the observed sensation vote, and it agrees best with the observed thermal sensation in transient thermal environment than PMV and Fiala model. Further studies should be carried out to improve performance of Chinese model for temperature alterations between "very hot" to "hot" environment, for prediction error in the temperature-fall situation of C5 (37-32°C) was over 0.5 scale.
在本研究中,构建了由两个低温阶段中的一个高温阶段组成的三种瞬态环境条件,从而形成先升温后降温的情况。招募了24名受试者(包括12名男性和12名女性),他们经历了所有三种测试场景。在实验全过程中测量了七个身体部位的皮肤温度。此外,在特定时刻通过问卷调查对热感觉进行了调查。应用包括PMV模型、菲阿拉模型和中国模型在内的热感觉模型来预测受试者的热感觉,并对它们进行了比较。结果表明,中国模型预测的大多数热感觉落在观察到的感觉投票的0.5刻度范围内,并且在瞬态热环境中,它与观察到的热感觉的一致性比PMV模型和菲阿拉模型更好。对于“非常热”到“热”环境之间的温度变化,应进一步开展研究以提高中国模型的性能,因为在C5(37 - 32°C)降温情况下的预测误差超过了0.5刻度。
