棉纺织车间的热舒适性研究

Research on thermal comfort in cotton textile workshop

以国家标准和相关热舒适研究为基础,调查了棉纺织车间的热舒适情况。测试了相关热舒适参数,计算出棉纺织车间的预测平均热感觉指数(PMV)和预计不满意者的百分比(PPD),分别与热感觉投票(TSV)值和热满意度投票(TS)结果进行对比,以判断PMV-PPD指标体系在棉纺织车间的适用情况。对棉纺织车间来说,计算的PMV值以及调查的TSV值均远远高于国家标准和国际标准要求的热舒适范围。考虑到国内纺织车间的实际情况,如果使用PMV-PPD指标体系来描述棉纺织车间的热环境,则应适当调宽PMV的要求范围,建议棉纺织车间的PMV应能满足-0.5<PMV<2。

The thermal comfort of the cotton textile workshop was researched based on national standards and related thermal comfort study. The thermal comfort parameters were measured to derive the predicted mean vote（ PMV） and predicted percentage dissatisfied（ PPD）. Comparison of the PMV and thermal sensation vote（ TSV）,PPD and thermal satisfaction（ TS） show applicability of PMV-PPD system to thermal comfort in cotton textile workshop. For cotton textile workshop,the PMV value and the TSV value are much higher than the required ranges of related national standards and international standards.Considering the actual condition of Chinese textile workshop,the required PMV value should be extended when the PMV-PPD system to describe the thermal environment of textile workshop. The PMV range of textile workshop is suggested as：- 0. 5 〈 PMV 〈 2.
