摘要
针对矿井的高温现象,分析了矿工热舒适性的影响因素,归纳出常用均匀环境下热舒适性评价方法,如预测平均热感觉评价PMV、预测不满意百分比PPD、平均辐射温度MRT、有效温度ET和标准有效温度SET,紧接着描述了几种非均匀环境下人体热舒适性评价指标,分别为加权PMV、等效均匀温度EHT、当量温度评价指标EQT、局部热感觉TSV,总结出在非均匀热环境的高温矿井中,可采用加权PMV指标用于矿工的热舒适性评价。
According to the high temperature phenomenon of the mine,the influencing factors of the thermal comfort of the miners are analyzed,and the evaluation methods of the thermal comfort in the commonly used uniform environment are summarized.For example,the average thermal sensory evaluation of PMV,the predicted dissatisfaction percentage PPD,the average radiation temperature MRT,the effective temperature ET and the standard effective temperature SET.Then,the evaluation criteria of human thermal comfort in several nonuniform environments are described as weighted PMV,equivalent uniform temperature EHT,equivalent temperature evaluation index EQT,and local thermal sensory TSV,and summed up in nonuniform Thermal environment of high temperature mines,the use of weighted PMV indicators for miners thermal comfort evaluation.
