灯暖浴霸环境下浴室人员热感觉研究

Research about Thermal Sensation of Experimenters under the Environment Heated by Bathroom Master

为了解夏热冬冷地区冬季灯暖浴霸的使用效果和人员在浴霸环境下的局部及整体热感觉,进行了浴霸环境下浴室人员热感觉研究。测定了浴室的环境参数,利用PMV模型计算预测投票值,并与人员实际热感觉投票值进行了对比分析。结果表明:浴霸开启后,浴室中垂直温度梯度增大,PMV值增大。人员整体热感觉始终大于0,除头部热感觉变化不大外,各部位热感觉变化趋势相似,且暖灯开启盏数越多,整体和局部热感觉投票值越大。通过回归分析得出,头部,手臂和腿部对整体热感觉的影响较为显著;浴霸可以满足人员想要改善浴室中寒冷感的需求;PMV模型无法准确预测该环境下人员的热感觉。

The research on the thermal sensation of people in the bathroom master environment was carried out to research the function of bathroom master and localized and overall thermal sensation of human body in winter of hot-summer and cold-winter area. After the environmental properties measured, the predicted mean vote was calculated by PMV model and compared with the practical thermal sensation vote value. Results show that: the vertical temperature gradient and PMV index increase after turning on the bathroom master;the overall thermal sensation is always greater than 0, except thermal sensation of the head does not change a lot, the trend of thermal sensation of all parts is similar,and the overall and localized thermal sensation vote values increase as more lamps are turned on;through regression analysis, the influence of head, arm and leg on the overall thermal sensation is more significant;bathroom master can meet the needs of improving the cold sensation in the bathroom;PMV model can not accurately predict the thermal sensation in this environment, and how to modify it remains to be considered.
